Posttraumatic stress disorder and adherence to medications in survivors of strokes and transient ischemic attacks

Post traumatic stress disorder associated hypothalamic-pituitary-adrenal axis dysregulation and physical illness

Conventional human stress responses are mediated by the sympathetic adrenal medullar (SAM) axis and the hypothalamic pituitary adrenal (HPA) axis. The SAM axis mediates the immediate response to stress through norepinephrine and epinephrine while the HPA axis mediates the slow response through corticosteroids, primarily cortisol, to effect systemic changes. Post Traumatic Stress Disorder (PTSD), a psychiatric disorder that develops in a small subset of people exposed to a traumatic event, may dysregulate these systems and result in increased risk of various clinical conditions. These conditions include but are not limited to cardiovascular disease, metabolic conditions, autoimmune diseases, neurocognitive disorders, and women's health complications such as preterm birth, polycystic ovarian syndrome, and endometriosis to name a few. This review focuses on how PTSD dysregulates the HPA axis, and further, how these alterations affect the immune system and physical health outcomes.

The Management of Depression and Anxiety in Primary Care: Examining Predictors of Adherence to a Psychopharmacological Collaborative Care Management Program for Veterans

Collaborative care management (CoCM) is an evidenced based approach to psychiatric treatment in primary care, yet literature examining factors associated with program adherence is lacking. This study analyzed predictors of adherence to a CoCM model of psychopharmacological treatment of depression and anxiety in primary care by conducting a retrospective cohort analysis on Veterans referred to a large VA Medical Center's CoCM program over an 18-month period. Baseline characteristics, symptomatic assessments, and covariates of interest were collected. For the primary outcome, the association between covariates and programmatic completion were analyzed. Secondary analyses assessed improvements in psychiatric symptoms. A total of 757 Veterans with depressive or anxiety disorders were included, and 256 completed the CoCM program. Baseline covariates associated with differences in completion rates included the following: age, contact with psychology prior to referral, baseline PHQ-9, baseline GAD-7, and a number of comorbid psychiatric/substance abuse covariates. After controlling for baseline differences, age remained a significant positive predictor of completion (OR 1.019, 95% CI 1.008‒1.030) and cannabis use a significant negative predictor (OR 0.507, 95% CI 0.275‒0.934). Both early improvement in PHQ-9 (OR 1.864, 95% CI 1.210‒2.872) and GAD-7 (OR 1.762, 95% CI 1.154‒2.691) scores were positive predictors. Secondary analyses showed that programmatic completion was associated with greater reductions in psychiatric symptoms. Results identified a number of modifiable parameters associated with differences in completion rates and greater symptomatic reduction for those who complete the program. Additional studies should be conducted examining interventions to optimize CoCM programs by supporting positive predictors while minimizing negative predictors.

Eye movement desensitisation and reprocessing for survivors of life-threatening medical events

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of eye movement desensitisation and reprocessing (EMDR), a psychological intervention programme, on symptoms related to traumatic stress in survivors of life-threatening medical events.

SECONDARY OBJECTIVES

to evaluate whether the effects of EMDR differ according to the nature of the medical event (associated diagnosis or setting), measured outcome (post-traumatic stress disorder (PTSD), anxiety, depression, or quality of life), or intervention (online, face-to-face, group or individual sessions).

Association of Posttraumatic Stress Disorder and Race on Readmissions After Stroke

BACKGROUND

There is limited research on outcomes of patients with posttraumatic stress disorder (PTSD) who also develop stroke, particularly regarding racial disparities. Our goal was to determine whether PTSD is associated with the risk of hospital readmission after stroke and whether racial disparities existed.

METHODS

The analytical sample consisted of all veterans receiving care in the Veterans Health Administration who were identified as having a new stroke requiring inpatient admission based on the International Classification of Diseases codes. PTSD and comorbidities were identified using the International Classification of Diseases codes and given the date of first occurrence. The retrospective cohort data were obtained from the Veterans Affairs Corporate Data Warehouse. The main outcome was any readmission to Veterans Health Administration with a stroke diagnosis. The hypothesis that PTSD is associated with readmission after stroke was tested using Cox regression adjusted for patient characteristics including age, sex, race, PTSD, smoking status, alcohol use, and comorbidities treated as time-varying covariates.

RESULTS

Our final cohort consisted of 93 651 patients with inpatient stroke diagnosis and no prior Veterans Health Administration codes for stroke starting from 1999 with follow-up through August 6, 2022. Of these patients, 12 916 (13.8%) had comorbid PTSD. Of the final cohort, 16 896 patients (18.0%) with stroke were readmitted. Our fully adjusted model for readmission found an interaction between African American veterans and PTSD with a hazard ratio of 1.09 ([95% CI, 1.00-1.20] P=0.047). In stratified models, PTSD has a significant hazard ratio of 1.10 ([95% CI, 1.02-1.18] P=0.01) for African American but not White veterans (1.05 [95% CI, 0.99-1.11]; P=0.10).

CONCLUSIONS

Among African American veterans who experienced stroke, preexisting PTSD was associated with increased risk of readmission, which was not significant among White veterans. This study highlights the need to focus on high-risk groups to reduce readmissions after stroke.

Compliance with medical regimen among hematological cancer patients and its association with symptoms of posttraumatic stress disorder and adjustment disorder

Background

Hematological cancer patients must comply with extensive medical instructions to prevent cancer progression or relapse. Psychological comorbidities and patient characteristics have been shown to affect compliance. However, the impact of posttraumatic stress disorder (PTSD) and adjustment disorder (AjD) on compliance in cancer patients remains unclear. This study aims to evaluate compliance in hematological cancer patients more comprehensively and to investigate its association with PTSD and AjD symptomatology as well as sociodemographic and medical factors.

Methods

Hematological cancer patients were cross-sectionally assessed via validated questionnaires for PTSD (PCL-5) and AjD (ADMN-20), and three internally developed items on compliance with medical regimen, with two referring to compliance behavior and one item assessing perceived difficulties with complying. Each compliance item was analyzed descriptively. Multiple linear regression models tested the association between compliance and PTSD and AjD symptomatology, sociodemographic and medical factors.

Results

In total, 291 patients were included (response rate 58%). Nine out of ten patients reported to either never (67%) or rarely (25%) change their medical regimen. However, 8% reported to change it once in a while or often. Compliance behavior was mostly rated as very easy (36%) or easy (45%) to implement. Nevertheless, 19% perceived it to be partly difficult or difficult to follow medical regimen. Symptoms of AjD (β = 0.31, p < 0.001) were associated with more difficulties to comply. Higher compliance behavior in turn was associated with stem cell transplantation (SCT) treatment (β = -0.21, p < 0.001) and lower education (β = -0.19, p = 0.002).

Conclusion

Although most patients indicated that they comply with medical regimen, a considerable subgroup of patients indicated subjectively perceived difficulties and thus seem to require additional support in implementing medical instructions possibly through improved medical communication and patient health literacy or shared decision-making.

Delirium and Previous Psychiatric History Independently Predict Poststroke Posttraumatic Stress Disorder

OBJECTIVES

Delirium is an acute brain dysfunction that has been correlated with adverse mental health outcomes, such as depression and posttraumatic stress disorder (PTSD). However, delirium has not been studied in relation to mental health outcomes after cerebrovascular events. This study aimed to examine the incidence of PTSD after nontraumatic intracerebral hemorrhage (ICH) and identify new predictors of poststroke PTSD symptoms.

METHODS

Clinical data were collected from 205 patients diagnosed with nontraumatic ICH. Demographics and hospital course data were examined. Univariate and multivariable correlational analyses were performed to determine predictors of PTSD symptoms. PTSD symptoms were assessed using PTSD checklist-civilian version (PCL-C) scores.

RESULTS

Diagnostic criteria for a positive PTSD screen (PCL-C score ≥44) were met by 13.7%, 20.2%, and 11.6% of nontraumatic patients with ICH at 3, 6, and 12 months, respectively. On univariate analysis, younger age, female sex, unemployed, and in-hospital delirium were correlated with higher PCL-C scores. In multivariable models, younger age, female sex, unemployed, in-hospital delirium, and a previous anxiety or depression diagnosis were associated with higher PCL-C scores at different follow-up times. Modified Rankin Scale scores were also positively correlated with PCL-C scores at each time point.

CONCLUSIONS

Delirium, previous psychiatric history, younger age, female sex, and unemployment status were found to be associated with a greater degree of posthemorrhagic stroke PTSD symptoms. More significant PTSD symptoms were also correlated with greater functional impairment. A better understanding of patient susceptibility to PTSD symptoms may help providers coordinate earlier interventions.

Lifetime and Acute Stress Predict Functional Outcomes Following Stroke: Findings From the Longitudinal STRONG Study

BACKGROUND

Stroke is a sudden-onset, uncontrollable event; stroke-related stress may impede rehabilitation and recovery. Lifetime stress may sensitize patients to experiencing greater stroke-related stress and indirectly affect outcomes. We examine lifetime stress as predictor of poststroke acute stress and examine lifetime and acute stress as predictors of 3- and 12-month functional status. We also compare acute stress and baseline National Institutes of Health Stroke Scale as predictors of poststroke functional status.

METHODS

Between 2016 and 2020 the STRONG Study (Stroke, Stress, Rehabilitation, and Genetics) enrolled adults with new radiologically confirmed stroke 2 to 10 days poststroke onset at 28 acute care US hospitals. Participants were interviewed 3 times: acute admission (acute stress; Acute Stress Disorder Interview), 3 months (Fugl-Meyer Upper Extremity motor impairment [Fugl-Meyer Upper Arm Assessment; N=431], modified Rankin Scale [3 months; N=542], Stroke Impact Scale-Activities of Daily Living [3 months; N=511], Lifetime Stress Exposure Inventory), and 12 months (modified Rankin Scale, N=533; Stroke Impact Scale 3.0 Activities of Daily Living; N=485; Telephone Montreal Cognitive Assessment; N=484) poststroke. Structural equation models examined whether acute stress predicted 3- and 12-month functional outcomes, and mediated an association between lifetime stress and outcomes controlling for demographics and initial National Institutes of Health Stroke Scale. Standardized betas are reported.

RESULTS

Sample (N=763) was 19 to 95 years old (mean=63; SD=14.9); 448 (58.7%) were male. Acute stress scores ranged from 0 to 14 (mean, 3.52 [95% CI, 3.31-3.73]). Controlling for age, gender, baseline National Institutes of Health Stroke Scale, and race and ethnicity, higher lifetime stress predicted higher acute stress (β=0.18, P<0.001), which predicted lower 3-month Fugl-Meyer Upper Arm Assessment scores (β=-0.19, P<0.001), lower Stroke Impact Scale 3.0 Activities of Daily Living scores at 3 months (β=-0.21, P<0.001) and 12 months (β=-0.21, P<0.001), higher modified Rankin Scale scores at 3 months (β=0.23, P<0.001) and 12 months (β=0.22, P<0.001), and lower 12-month Telephone Montreal Cognitive Assessment scores (β=-0.20, P<0.001). Acute stress predicted 12-month tMoCA (χ2[1]=5.29, P=0.022) more strongly, 3-month and 12-month modified Rankin Scale and SIS scores as strongly (all Ps>0.18), but Fugl-Meyer scores (χ2[1]=7.01, P=0.008) less strongly than baseline National Institutes of Health Stroke Scale.

CONCLUSIONS

Lifetime stress/trauma is associated with more poststroke acute stress, which is associated with greater motor and cognitive impairment and disability 3 and 12 months poststroke. Poststroke interventions for acute stress may help mitigate stroke-related disability.

Neurologic Injury-Related Predisposing Factors of Post-Traumatic Stress Disorder: A Critical Examination

The present review aimed to identify the means through which neurologic injury can predispose individuals to Post-Traumatic Stress Disorder (PTSD). In recent years, comprehensive studies have helped to clarify which structures in the central nervous system can lead to distinct PTSD symptoms-namely, dissociative reactions or flashbacks-when damaged. Our review narrowed its focus to three common neurologic injuries, traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), and stroke. We found that in each of the three cases, individuals may be at an increased risk of developing PTSD symptoms. Beyond discussing the potential mechanisms by which neurotrauma may lead to PTSD, we summarized our current understanding of the pathophysiology of the disorder and discussed predicted associations between the limbic system and PTSD. In particular, the effect of noradrenergic neuromodulatory signaling on the hypothalamic pituitary adrenal (HPA) axis as it pertains to fear memory recall needs to be further explored to better understand its effects on limbic structures in PTSD patients. At present, altered limbic activity can be found in both neurotrauma and PTSD patients, suggesting a potential causative link. Particularly, changes in the function of the limbic system may be associated with characteristic symptoms of PTSD such as intrusive memories and acute psychological distress. Despite evidence demonstrating the correlation between neurotrauma and PTSD, a lack of PTSD prognosis exists in TBI, SAH, and stroke patients who could benefit from early treatment. It should be noted that PTSD symptoms often compound with pre-existing issues, further deteriorating health outcomes for these patients. It is ultimately our goal to clarify the relationship between neurotrauma and PTSD so that earlier diagnoses and appropriate treatment are observed in clinic.

Acute stress symptoms 1-2 weeks after stroke predict the subsequent development of post-traumatic stress symptoms: A prospective cohort study

OBJECTIVE

To date no research has examined the potential influence of acute stress symptoms (ASD) on subsequent development of post-traumatic stress disorder (PTSD) symptoms in stroke survivors. Our objective was to examine whether acute stress symptoms measured 1-2 weeks post-stroke predicted the presence of post-traumatic stress symptoms measured 6-12 weeks later.

DESIGN

Prospective within-groups study.

METHODS

Fifty four participants who completed a measure of acute stress disorder at 1-2 weeks following stroke (time 1) and 31 of these participants completed a measure of posttraumatic stress disorder 6-12 weeks later (time 2). Participants also completed measures of stroke severity, functional impairment, cognitive impairment, depression, anxiety, pre-morbid intelligence and pain across both time points.

RESULTS

Some 22% met the criteria for ASD at baseline and of those, 62.5% went on to meet the criteria for PTSD at follow-up. Meanwhile two of the seven participants (28.6%) who met the criteria for PTSD at Time 2, did not meet the ASD criteria at Time 1 (so that PTSD developed subsequently). A hierarchical multiple regression analysis indicated that the presence of acute stress symptoms at baseline was predictive of post-traumatic stress symptoms at follow-up (R2 = .26, p < .01). Less severe stroke was correlated with higher levels of post-traumatic stress symptoms at Time 2 (rho = .42, p < .01).

CONCLUSIONS

The results highlight the importance of early assessment and identification of acute stress symptoms in stroke survivors as a risk factor for subsequent PTSD. Both ASD and PTSD were prevalent and the presence of both disorders should be assessed.

Evaluation & Treatment of Psychological Effects of Stroke

Strokes are a common medical condition in the United States, including in Delaware. An under-recognized effect of stroke is the impact on mood that often occurs. Many individuals develop depression, anxiety, PTSD, and other psychological sequelae. These disorders can significantly affect their lives and their relationships. The emotional effects of stroke pose a public health problem for our residents, leading to devastating decreases in the quality of life for the patient and the family. These challenges negatively impact the community due to the associated healthcare and economic burdens. The population of the State of Delaware is growing, and the proportion of senior residents, who are also at greater risk for strokes, is also increasing. Strokes will remain an ongoing important clinical concern for our healthcare providers. Emotional changes after a stroke will occur in many Delaware residents who suffer a stroke. The emotional sequelae of stroke are under-treated. It is critical for healthcare professionals to be trained to recognize, assess, and treat the psychological disorders that can result from having a stroke. This article provides an overview of the major psychological effects of stroke, recommended assessment tools, promising treatment trends, and directions for further research. Improving our ability to detect and treat these difficult emotional challenges can facilitate effective treatment and prevention strategies and increase quality of life for stroke survivors, their loved ones, and their communities.

Skin Conductance Reactivity as a Predictor of Stroke-induced Posttraumatic Stress Disorder Symptoms: A Dimensional Approach

Background

Posttraumatic stress disorder (PTSD) symptoms can develop following acute, life-threatening medical events. This study explores a potential biomarker of PTSD risk that is novel to a medical trauma population: a noninvasive, mobile skin conductance (SC) measurement.

Methods

Participants (N=64) were enrolled in-hospital following a stroke or transient ischemic attack (TIA). Mobile measurement of SC reactivity to recalling the stroke/TIA traumatic event was conducted at hospital bedside in the days following the stroke/TIA. PTSD symptoms that developed in response to the stroke/TIA were measured at 1-month follow-up. We tested the association between SC reactivity and total 1-month PTSD symptoms, as well as PTSD symptom dimensions of fear and dysphoria.

Results

In unadjusted analyses, there were significant positive associations between in-hospital SC reactivity to recalling the stroke/TIA traumatic event and higher-order fear-related symptoms (r=.30, p=.016), as well as lower-order fear-related symptoms of anxious arousal (r=.27, p=.035) and avoidance (r=.25, p=.043) at 1 month. Associations between SC reactivity and the fear, anxious arousal, and avoidance symptom dimensions remained significant in multivariable regression models that adjusted for relevant covariates including age, gender, stroke severity, medical comorbidity, and psychosocial factors. Although there was a positive association observed between SC reactivity to recalling the stroke/TIA event and total PTSD symptom severity at 1-month follow-up, it did not reach the level of statistical significance (r=.23, p=.070). Further, no significant association was detected for dysphoria-related symptoms (r=.11, p=.393).

Conclusions

This is the first study to test the prospective association of SC reactivity with PTSD symptom development following a medical trauma. The findings indicate that mobile measures of SC reactivity may be useful for in-hospital identification of individuals at risk for fear-related PTSD symptom development following a medical event and highlight the potential mechanisms involved in the development of these symptoms following a medical event.

Effectiveness of repetitive transcranial magnetic stimulation combined with a brief exposure procedure for post-stroke posttraumatic stress disorder

The incidence of posttraumatic stress disorder (PTSD) following stroke ranges from 6.5 % to 25 %. Presently few studies have focused on its treatment. Repetitive transcranial magnetic stimulation (rTMS) is often applied as a rehabilitation method after stroke, and it also represents a novel approach to PTSD. The aim of this study was to explore the effect of rTMS (or combined with a brief stroke re-exposure) on treating post-stroke PTSD. Sixty participants with post-stroke PTSD were randomly assigned into three groups (rTMS + brief exposure group, TMS + BE; rTMS alone group, TMS; sham treatment group, ST) and received 10 sessions of treatment accordingly over two weeks. Changes in PTSD symptoms (Impact of Event Scale-Revised, IES-R) were evaluated at pre-treatment (T1), the end of the first (T2), and the end of the second treatment week (T3). At the three-month follow-up (T4), a PTSD interview and IES-R assessment were given. Results showed that from T1 to T3, IES-R (and its intrusion subscale) scores of TMS + BE group and TMS group were significantly lower than the ST group, and the effect remained at three-month follow-up. The treatment effect was comparable between TMS + BE group and TMS group at T3, however, it was better for TMS + BE group than TMS group at T2, indicating a brief exposure promotes the effect of rTMS. At follow-up, the rates of PTSD were lower in TMS + BE group and TMS group than ST group. In conclusion, rTMS can effectively treat post-stroke PTSD and the effects may be accelerated by combining a brief exposure procedure.

Psychosocial factors correlate with adherence to medications among cardiovascular outpatient clinics in Jordan

BACKGROUND

Adherence to medications is a significant element of self-care behaviors for patients with cardiovascular diseases (CVDs). Non-adherence to cardiovascular medications is the major risk for poor outcomes following any cardiac event. However, there is a lack of studies that addressed medication adherence among patients with CVDs attending outpatient clinics in Arabic countries, including Jordan. Thus, this study purposed to assess the psychosocial factors (e.g. depression, anxiety, stress, social support and self-esteem) and their correlation with adherence to medications among patients with CVDs attending outpatient clinics in Jordan.

METHODS

A total of 395 Jordanian patients attending CVDs outpatient clinics at government, military and private healthcare facilities were recruited.

RESULTS

Our study findings showed that 31.4% of the patients reported complete adherence to their medications. The proportion of psychological reactions reported by the participants was 72.1% for depressive symptoms, 62.6% for anxiety and 50.1% for stress; 79.7% had moderate and normal social support, and 44% had low self-esteem. Depression, anxiety and stress had a significant negative correlation with adherence to medications; however, self-esteem had a significant positive relationship with adherence to medications. In addition, depression, anxiety and stress were the main predictors of adherence to medications.

CONCLUSION

Our findings might aid in paving the road for designing and developing strategies and interventions to increase adherence to medications and minimize these psychosocial problems among CVD patients in outpatient clinics.

Correlates of Skin Conductance Reactivity to Stroke-Related Trauma Reminders During Hospitalization for Stroke

Objective

Although several risk factors for stroke-induced posttraumatic stress disorder (PTSD) have been identified, objective risk measures that can be detected in the acute aftermath of these events are needed. This study is the first to collect an objective measure of psychophysiological arousal-skin conductance (SC) reactivity to a trauma interview-in patients after stroke or transient ischemic attack (TIA) and investigate correlates of SC reactivity.

Methods

Mobile SC measurement during a resting baseline and standardized trauma interview was performed in-hospital in 98 individuals following stroke/TIA. We examined associations between several stroke-induced PTSD risk factors (sociodemographic, psychosocial, and medical characteristics) and SC reactivity to a trauma interview involving a free-response recalling of the stroke/TIA event.

Results

Of the sociodemographic, psychosocial, medical characteristics examined as correlates to SC reactivity to recalling the stroke/TIA event, 2 factors reflecting aspects of prior and in-hospital experience were significantly associated with this indicator of sympathetic nervous system activation. A greater cumulative trauma burden was significantly associated with greater SC reactivity (r = .23, P = .04). Additionally, individuals administered benzodiazepines in-hospital had significantly greater SC reactivity to recalling the stroke/TIA event (M = 1.51, SD = 1.52) than those who were not (M = 0.76, SD = 1.16; P = .01). Greater cumulative trauma burden remained significantly associated with greater SC reactivity when adjusting for age and in-hospital benzodiazepine administration (β=0.22, P = .04).

Conclusion

This study demonstrated that SC reactivity was related to both behavioral and psychological risk factors for PTSD after a stroke/TIA event. Additionally, we demonstrated the feasibility of a low-cost, mobile measurement of SC that can be conducted in-hospital in a novel patient population: individuals with a medical trauma. With this measure, we were able to identify those individuals with the greatest trauma-related sympathetic nervous system reactivity in the days following a medical trauma. Future research is needed to determine whether SC reactivity may be leveraged in the development of brief, noninvasive screening measures for enhancing PTSD risk prediction.

Coping Strategies and Posttraumatic Growth Following Transient Ischemic Attack: A Qualitative Study

A transient ischemic attack (TIA) is defined as a temporary neurological dysfunction due to focal brain ischemia. We aimed to identify common coping strategies and the possible occurrence of posttraumatic growth in TIA patients. Semistructured interviews were conducted with TIA patients three months after TIA. We asked the participants about possible changes in the aftermath of their TIA and their way of coping with said changes. All interviews were tape-recorded and subsequently transcribed verbatim. Thematic content analysis was performed to identify main categories and themes. Seventeen patients with a median age of 66 years completed the semistructured interviews. Qualitative content analysis revealed 332 single codes, from which the three main categories "impairments as a consequence of TIA", "coping strategies" and "posttraumatic growth" were generated. The main categories were further subdivided into seven categories and thirty-six themes. TIA patients may suffer from various physical impairments, which also involve medication side effects. Activating resources on the one hand, and avoiding negative thoughts and feelings on the other hand, were identified to be the relevant coping strategies in TIA patients. Posttraumatic growth seems to be a common phenomenon after TIA, which may have important implications for treatment and rehabilitation.

Psychometric properties of the post-traumatic stress disorder checklist for DSM-5 (PCL-5) in Chinese stroke patients

BACKGROUND

Stroke is a devastating disease and can be sufficiently traumatic to induce post-traumatic stress disorder (PTSD). Post-stroke PTSD is attracting increasing attention, but there was no study assessing the psychometric properties of the PCL-5 in stroke populations. Our study was conducted to examine the psychometric properties of the PTSD Checklist for DSM-5 (PCL-5) in Chinese stroke patients.

METHODS

This was a cross-sectional observational study conducted at our hospital. Three hundred and forty-eight Chinese stroke patients came to our hospital for outpatient service were recruited. They were instructed to complete the PCL-5 scales and were interviewed for PTSD diagnosis with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). The cutoff scores, reliability and validity of the PCL-5 were analyzed.

RESULTS

PCL-5 scores in our sample were positively skewed, suggesting low levels of PTSD symptoms. The reliability of PCL-5 was good. Exploratory and confirmatory factor analyses indicated acceptable construct validity, and confirmed the multi-dimensionality of the PCL-5. By CFA analysis, the seven-factor hybrid model demonstrated the best model fit. The PCL-5 also showed good convergent validity and discriminant validity. Receiver operating characteristic (ROC) analyses revealed a PCL-5 score of 37 achieved optimal sensitivity and specificity for detecting PTSD.

CONCLUSIONS

Our findings supported the use of PCL-5 as a psychometrically adequate measure of post-stroke PTSD in the Chinese patients.

Eye movement desensitization and reprocessing for post-stroke post-traumatic stress disorder: Case report using the three-phase approach

Medically-induced post-traumatic stress disorder (PTSD) is substantially more prevalent than PTSD in the general population. In people with stroke, it can impact as many as 23% of patients, with negative effects on mental health as well as stroke-related disability. Medically-induced PTSD may have unique features compared to other forms of PTSD, and therefore there is a pressing need to evaluate existing treatments for PTSD in this context. The current study reports on the feasibility, safety, and efficacy of Eye Movement Desensitization and Reprocessing (EMDR) for PTSD subsequent to a pontine stroke. Using a quasi-experimental case design, a 44-year-old Caucasian woman received EMDR delivered via telehealth. Self-report measures were obtained at baseline, pre-EMDR, and post-EMDR, with brief neuropsychological testing pre/post-EMDR. After 3 sessions of EMDR, the patient no longer met criteria for PTSD, and showed clinically significant reductions in depressive and generalized anxiety symptoms. With proper safety provisions, it is feasible to deliver EMDR via telehealth to alleviate post-stroke PTSD. Reduced linguistic demands of EMDR may be particularly appealing for persons with neurological disorders as compared to other trauma therapies. Further work is also needed to understand the parameters of baseline neuropsychological function that could impact response to intervention.

Supportive psychological therapy can effectively treat post-stroke post-traumatic stress disorder at the early stage

Post-traumatic stress disorder (PTSD) can develop after stroke attacks, and its rate ranges from 4 to 37% in the stroke population. Suffering from PTSD not only decreases stroke patient’s quality of life, but also relates to their non-adherence of treatment. Since strokes often recur and progress, long-term medical management is especially important. However, previous studies generally focused on the epidemiological characteristics of post-stroke PTSD, while there are literally no studies on the psychological intervention. In our study, 170 patients with a first-ever stroke during the acute phase were recruited. They were randomized into Psycho-therapy group 1 and Control group 1, and were administered with preventive intervention for PTSD or routine health education, respectively. At 2-month follow-up, PTSD symptoms were evaluated. Participants who were diagnosed with post-stroke PTSD were further randomized into Psycho-therapy group 2 and Control group 2, and received supportive therapy or routine health counseling, respectively. At 6-month follow-up (1°month after the therapy was completed), PTSD symptoms were re-evaluated. Our results showed that at 2-month, the PTSD incidence in our series was 11.69%, and the severity of stroke was the only risk factor for PTSD development. The preventive intervention was not superior to routine health education for PTSD prevention. At 6-month, results indicated the supportive therapy did have a fine effect in ameliorating symptoms for diagnosed PTSD patients, superior to routine health counseling. Thus, our study was the first to provide evidence that the supportive therapy was effective in treating post-stroke PTSD early after its diagnosis. This clinical trial was preregistered on www.chictr.org.cn (ChiCTR2100048411).

Underlying Role of Rumination-Mediated Attachment Style Plays in PTSD after TIA and Stroke

Objective: Attachment and rumination were examined as the intermediary variables on post-traumatic stress disorder and medication compliance in stroke or TIA patients. Methods: A total of 300 participants with stroke or TIA from the Second Hospital of Hebei Province were selected. Patients accomplished NIHSS, ABCD2, ECR, RSQ, and RRS on admission. After 3 months, the PCL-C and MMAS were collected. Results: In the stroke or TIA patients, the incident of PTSD was 7.7%; PTSD scores were significantly associated with attachment anxiety (r = 0.225, p < 0.01), symptom rumination (r = 0.197, p < 0.01), and obsessive thinking (r = 0.187, p < 0.01). After the Sobel test analysis and verification by the Baron and Kenny’s stepwise approach we found that ruminant mediated the relationship between attachment anxiety and PTSD; obsessive thinking mediated the relationship between attachment anxiety and PTSD. Conclusions: The relationship between attachment anxiety and PTSD was positively predicted by rumination and obsessive thinking. Adult attachment style, rumination, and PTSD scores may not predict medication compliance.

Hereditary Hemorrhagic Telangiectasia Associating Neuropsychiatric Manifestations with a Significant Impact on Disease Management-Case Report and Literature Review

(1) Background: Genetic hereditary hemorrhagic telangiectasia (HHT) is clinically diagnosed. The clinical manifestations and lack of curative therapeutic interventions may lead to mental illnesses, mainly from the depression-anxiety spectrum. (2) Methods: We report the case of a 69-year-old patient diagnosed with HHT and associated psychiatric disorders; a comprehensive literature review was performed based on relevant keywords. (3) Results: Curaçao diagnostic criteria based the HHT diagnosis in our patient case at 63 years old around the surgical interventions for a basal cell carcinoma, after multiple episodes of epistaxis beginning in childhood, but with a long symptom-free period between 20 and 45 years of age. The anxiety-depressive disorder associated with nosocomephobia resulted in a delayed diagnosis and low adherence to medical monitoring. A comprehensive literature review revealed the scarcity of publications analyzing the impact of psychiatric disorders linked to this rare condition, frequently associating behavioral disengagement as a coping strategy, psychological distress, anxiety, depression, and hopelessness. (4) Conclusions: As patients with HHT face traumatic experiences from disease-related causes as well as recurring emergency hospital visits, active monitoring for mental illnesses and psychological support should be considered as part of the initial medical approach and throughout the continuum of care.

Contributing Factors and Induced Outcomes of Psychological Stress Response in Stroke Survivors: A Systematic Review

Background

Remarkable evidence indicates that psychological stress is significantly associated with stroke. However, a uniform recommendation to identify and alleviate poststroke psychological stress responses and improve postmorbid outcomes is not currently available. Thus, this systematic review aimed to summarize the types of poststroke psychological stress, measurement tools, contributing factors, and outcomes.

Methods

This systematic review was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A literature search was conducted in PubMed, Web of Science, Embase, CNKI, WanFangData, and CQVIP from database inception to November 2021. Cross-sectional and longitudinal studies were included in this research. Quality assessment was performed based on the National Institutes of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

Results

Eighteen quantitative, peer-reviewed studies were included for analysis. Selected articles mainly investigated perceived stress and posttraumatic stress disorder after stroke. We classified the contributing factors into four categories: sociodemographic factors, clinical disease factors, psychological factors, and behavioral and lifestyle factors. The postmorbid outcomes were divided into three categories: clinical disease outcomes, psychological outcomes, and behavioral and quality of life outcomes.

Conclusions

Compared to common patients, stroke survivors with the following characteristics suffered an increased psychological stress response: younger age, the presence of caregivers, depression, unsuitable coping strategies, etc. Meanwhile, lower quality of life, worse drug compliance, worse functional independence, and more severe mental disorders were significantly associated with increased psychological stress symptoms. Further studies are required to provide more trustworthy and meaningful references for mitigating the damage caused by psychological stress after stroke.

Posttraumatic Stress Symptoms After Stroke: The Effects of Anatomy and Coping Style

BACKGROUND

Posttraumatic stress disorder (PTSD) can be triggered by life-threatening medical emergencies, such as stroke. Data suggest that up to 25% of stroke survivors will develop PTSD symptomatology, but little is known about predisposing factors. We sought to examine whether neuroimaging measures and coping styles are related to PTSD symptoms after stroke.

METHODS

Participants were survivors of first-ever, mild-moderate ischemic stroke, or transient ischemic attack from the TABASCO study (Tel Aviv Brain Acute Stroke Cohort). All participants underwent a 3T magnetic resonance imaging at baseline and were examined 6, 12, and 24 months thereafter, using neurological, neuropsychological, and functional evaluations. At baseline, coping styles were evaluated by a self-reported questionnaire. PTSD symptoms were assessed using the PTSD checklist. Data were available for 436 patients.

RESULTS

Forty-eight participants (11%) developed probable PTSD (PTSD checklist ≥44) during the first year after the stroke/transient ischemic attack. Stroke was more likely to cause PTSD than transient ischemic attack. Stroke severity, larger white matter lesion volume, and worse hippocampal connectivity were associated with PTSD severity, while infarct volume or location was not. In a multivariate analysis, high-anxious and defensive coping styles were associated with a 6.66-fold higher risk of developing poststroke PTSD ([95% CI, 2.08-21.34]; P<0.01) compared with low-anxious and repressive coping styles, after adjusting for age, education, stroke severity, brain atrophy, and depression.

CONCLUSIONS

In our cohort, PTSD was a common sequela among stroke survivors. We suggest that risk factors for PTSD development include stroke severity, white matter damage, and premorbid coping styles. Early identification of at-risk patients is key to effective treatment.

An Evidence-Based Nursing Intervention Decreases Anxiety, Depression, Sleep Quality and Somatic Symptoms of Patients with Acute Ischemic Stroke

PURPOSE

This study aimed to explore the effects of evidence-based nursing (EBN) intervention on anxiety, depression, sleep quality and somatic symptoms of patients with acute ischemic stroke (AIS).

METHODS

The eligible AIS patients were randomized into the intervention group and control group in a 1:1 ratio. Patients in both groups received routine nursing care. On the basis of routine nursing, patients in the intervention group also received EBN. Self-rating anxiety scale (SAS), self-rating depression scale (SDS), Pittsburgh Sleep Quality Index (PSQI), and the Patient Health Questionnaire-15 (PHQ-15) were used to assess patients' anxiety, depression, sleep quality, and somatic symptoms at baseline (T0) and 6 months after intervention (T1), respectively.

RESULTS

There was no difference in SAS, SDS, PSQI, and PHQ-15 scores at T0 between the 2 groups (all P > 0.05). Comparing to the control group, the intervention group had significantly lower SAS and SDS scores at T1 (P = 0.002, P < 0.001, respectively). The SAS and SDS score changes (T1-T0) were more evident in the intervention group than in the control group (all P < 0.001). No difference of PSQI or PHQ-15 score between the 2 groups was observed at T1. However, the PSQI and PHQ-15 score changes were more evident in the intervention group than in the control group (P = 0.044 and P = 0.007, respectively).

CONCLUSION

EBN invention significantly improved anxiety, depression, sleep quality and somatic symptoms of patients with AIS.

Adherence to antiretroviral therapy mediates the link between posttraumatic stress disorder symptoms and health-related quality of life

Human immunodeficiency virus is one of the trauma-inducing chronic illnesses with attendant-negative impact on health-related quality of life. Substantial literature exists on the association of posttraumatic stress disorder symptoms and health-related quality of life among people living with human immunodeficiency virus, but little is known about the pathways explaining this link. This study therefore examined the mediating role of adherence to antiretroviral therapy in the association between posttraumatic stress disorder symptoms and health-related quality of life among people living with human immunodeficiency virus. Nine hundred and sixty-nine people living with human immunodeficiency virus in Nigeria who were on antiretroviral therapy completed measures of posttraumatic stress disorder symptoms, adherence to antiretroviral therapy, and health-related quality of life. Hayes PROCESS macro for SPSS was used to analyse the data. Adherence to antiretroviral therapy mediated the association between posttraumatic stress disorder symptoms and health-related quality of life in the relationship and treatment impact domains, implying that poor adherence to antiretroviral therapy is a pathway through which posttraumatic stress disorder symptoms exert negative influence on health-related quality of life of people living with human immunodeficiency virus. Interventions aimed at reducing the impact of posttraumatic stress disorder symptoms on quality of life of people living with human immunodeficiency virus should focus on improving clients’ level of adherence to antiretroviral therapy treatment.

"Lessons Learned" Preventing Recurrent Ischemic Strokes through Secondary Prevention Programs: A Systematic Review

Recurrent ischemic strokes are a cause of significant healthcare burdens globally. Patients with uncontrolled vascular risk factors are more likely to develop recurrent ischemic strokes. This study aims to compile information gained from current secondary prevention programs. A pre-defined literature search strategy was applied to PubMed, SCOPUS, CINAHL, and Google Scholar databases, and studies from 1997 to 2020 were evaluated for quality, study aims, and outcomes. The search produced 1175 articles (1092 after duplicates were removed) and titles were screened; 55 titles were retained for the full-text analysis. Of the remaining studies, 31 were retained for assessment, five demonstrated long-term effectiveness, eight demonstrated short-term effectiveness, and 18 demonstrated no effectiveness. The successful studies utilized a variety of different techniques in the categories of physical fitness, education, and adherence to care plans to reduce the risk of recurrent strokes. The lessons we learned from the current prevention programs included (1) offer tailored care for underserved groups, (2) control blood pressure, (3) provide opportunities for medication dosage titration, (4) establish the care plan prior to discharge, (5) invest in supervised exercise programs, (6) remove barriers to accessing care in low resource settings, and (7) improve the transition of care.

Occurence of Post-Traumatic Stress Symptoms, Anxiety and Depression in the Acute Phase of Transient Ischemic Attack and Stroke

Rates of post-traumatic stress symptoms, anxiety and depression are increased in patients having experienced a transient ischemic attack (TIA) or stroke several months ago. However, data of psychiatric symptoms in the acute phase within the first days after ictus are lacking. In 20 patients with stroke and 33 patients with TIA we assessed disease severity by means of the NIHSS, levels of depression and anxiety by HADS, PTSD-like symptoms by PC-PTSD, quality of life (HrQoL) by SF-12, and coping style by brief COPE Inventory within the first 5 days after ictus. NIHSS on admission was lower in patients with TIA (0 ± 1) than in patients with stroke (3 ± 2, p < 0.001). HADS depression score was significantly higher in patients with stroke (7.0 ± 4.5) than in patients with TIA (4.9 ± 4.0). HADS anxiety score, HrQoL and coping styles were similar between TIA and stroke patients (p > 0.05). 5 and 3 of 33 TIA patients as well as 4 and 3 of 20 stroke patients had at least 11 points in the HADS anxiety and depression score respectively (p = 0.001). 2 of 33 TIA patients and 2 of 20 stroke patients had more than 2 points in the PC-PTSD (p = 0.646). We did not find consistent correlations between the NIHSS and the psychometric parameters. Within the first five days after patients having experienced a TIA or stroke PTSD-like, anxious and depressive symptoms are more common than in the general population. As the acute psychological status after ictus is predictive for psychiatric comorbidity years later physicians should pay attention and adequately treat psychiatric symptoms already in the acute phase of stroke.Trial Registration: German Clinical Trials Register, DRKS00021730, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00021730 , registered 05/19/2020- Retrospectively registered.

Effect of cohabiting partners on the development of posttraumatic stress symptoms after emergency department visits for stroke and transient ischemic attack

OBJECTIVE

Partners can be beneficial for patients experiencing stressful health events such as a stroke/transient ischemic attack (TIA). During such events, however, partners may exacerbate early distress. The present study tested whether having a cohabiting partner modified the association between patients' early perceptions of threat (e.g., feeling vulnerable, helpless) and longer-term posttraumatic stress symptoms (PTSS).

METHODS

Participants (N = 328) were drawn from an observational cohort study of patients evaluated for stroke/TIA at an urban academic hospital between 2016 and 2019. Participants self-reported emergency department (ED) threat perceptions and PTSS secondary to the stroke/TIA at three days and one month post-event.

RESULTS

Cohabiting partner status modified the association of ED threat with early PTSS. Patients with a cohabiting partner exhibited a positive association between ED threat and early PTSS, B = 0.12, p < .001; those without a cohabiting partner did not, B = 0.04, p = .067. A cohabiting partner was protective only for patients who initially reported low levels of ED threat, as patients with a cohabiting partner who reported low levels of ED threat also had lower early PTSS, B = -0.15, p = .016; at high levels of ED threat, a cohabiting partner was not protective, B = -0.02, p = .68. ED threat was associated with PTSS at one month, B = 0.42, p < .001, but cohabiting partner status did not modify the association.

CONCLUSIONS

ED threat perceptions were positively associated with early PTSS only for patients with a cohabiting partner. For patients who do not initially experience a stroke/TIA event as threatening, cohabiting partners may help patients maintain psychological equanimity.

Prevalence and influencing factors of chronic post-traumatic stress disorder in patients with myocardial infarction, transient ischemic attack (TIA) and stroke - an exploratory, descriptive study

BACKGROUND

Cardio- and cerebrovascular events such as myocardial infarction (MI), stroke and transient ischemic attack (TIA) are leading causes of death and disability and have also been associated with poor mental outcomes. In addition, cardio- and cerebrovascular events may pose the risk of experiencing a sudden traumatic occurrence of symptoms during ictus and thus contribute to high rates of PTSD as well as high rates of subsequent depression and anxiety. Moreover, MI, TIA and stroke survivors with PTSD, depressive and anxiety symptoms may have poorer health-related quality of life (HRQoL) and poorer disease prognosis than patients who do not develop psychiatric symptoms after ictus. However, data on the prevalence of PTSD, anxiety and depression, as well as the HRQoL, coping strategies and potential risk factors for development of PTSD in these patients, are rare.

METHODS

In an exploratory, descriptive study we interviewed 112 patients (54 MI, 18 TIA, 40 stroke; mean age: 69.5 years, 55.4% males) from three general physician practices and used psychometric self-assessment tools to determine the occurrence of PTSD and psychosomatic comorbidity, anxiety and depression and to assess HRQoL and coping strategies. We evaluated disease severity and compared the patient groups to each other. Moreover, we assessed psychological outcome differences between patients with or without PTSD after ictus.

RESULTS

The prevalence of PTSD after MI, TIA and stroke was 23.2%. The patients who developed PTSD had higher rates of depression, anxiety and maladaptive coping as well as reduced HRQoL. Adaptive coping was positively related to better mental HRQoL and negatively related to anxiety and depression. Disease severity of MI, TIA and stroke was not related to PTSD, depression, anxiety or physical HRQoL.

CONCLUSIONS

Experiencing MI, TIA or stroke means confronting a life-threatening event for those affected and, therefore, these can be regarded as traumatic events. Cerebral and cardiovascular events increase the risk of developing chronic PTSD with subsequent increased depression and anxiety and reduced HRQoL. These findings emphasize the need for early screening and diagnosis of PTSD in somatically ill patients, which should be followed by specialized treatment, as PTSD hampers overall (somatic) disease prognosis.

Prevalence and correlates of post-traumatic stress disorder after ischaemic stroke

Although most often considered a consequence of traumatic event, post-traumatic stress disorder (PTSD) also occurs after illness. The aim of this study was to establish prevalence of PTSD in patients with ischaemic stroke (IS) and its correlation to lesion location, degree of disability, age, gender and marital status. The study included 85 patients with IS. PTSD was diagnosed using a modified version of the PTSD Checklist Specific for a stressor (PCL-S). Depression and anxiety were assessed using Hospital Anxiety and Depression Scale (HADS). We defined stroke localisation as right cerebral hemisphere, left cerebral hemisphere, brainstem and cerebellum. Stroke severity was measured using the modified Rankin scale (mRS). Demographic information including age, gender and marital status was collected from medical history. Of the 85 patients with IS, 11 (12.9%) fulfilled PCL-S criteria for PTSD. We found a positive correlation between PTSD and higher degree of disability, P < 0.001. Patients with PTSD had lesions more frequently localised in the right cerebral hemisphere and the brainstem. We found no statistically significant correlation of PTSD with age, gender and marital status. Our results show that a significant number of IS patients develop PTSD after IS. Determining correlates of post-stroke PTSD can help to identify those at higher risk for its development. If proven by additional large sample studies, more patients can benefit from screening for the PTSD symptoms.

Neuropsychiatric Complications after Stroke

Neuropsychiatric disturbances represent a common and uniquely challenging consequence of stroke. These disorders arise at the intersection of lesion-related brain dysfunction and psychological distress related to the event and its aftermath, making it difficult to identify what symptom is a direct physiological consequence of the stroke. Depression, anxiety, fatigue, apathy, emotionalism, and anger are the most common of these syndromes, and posttraumatic stress disorder related to the stroke event has become increasingly recognized as a relevant entity. Mania, obsessive-compulsive disorder, and psychosis are less commonly encountered but potentially highly debilitating conditions that may be underrecognized. Early identification and treatment may mitigate functional impairment and improve quality of life. Evidence-based guidelines from the general population are often relied upon to guide treatment. Further research is needed to understand and tailor treatment of these disorders in the poststroke population.

Impact of peritraumatic distress on posttraumatic stress disorder symptoms at 6 months after acute coronary syndrome: a prospective cohort study

Background: Posttraumatic stress disorder (PTSD) symptoms are known to occur after acute coronary syndrome (ACS). Peritraumatic distress has been indicated as a risk factor for PTSD and can be measured by the Peritraumatic Distress Inventory (PDI). However, no studies have yet measured peritraumatic distress after ACS using the PDI to predict PTSD. Objectives: This prospective cohort study examined the impact of peritraumatic distress on PTSD symptoms at 6 months after ACS. Methods: We used the PDI to assess peritraumatic distress in patients treated for ACS at a teaching hospital in Tokyo within 7 days after percutaneous coronary intervention. They were followed up over the next 6 months and were assessed for PTSD symptoms at 6 months using the Impact of Event Scale-Revised. The association between peritraumatic distress and PTSD symptoms was examined by multiple linear regression analysis. Results: The study enrolled 101 ACS patients, and 97 completed the follow-up assessment. PDI total score was an independent predictor of PTSD symptoms after adjustment for potential covariates (beta = 0.38; p < 0.01). Limitations: The results were obtained from a single teaching hospital and assessment of PTSD symptoms was questionnaire based. Conclusion: We provide the first evidence that PDI score can predict the development of PTSD symptoms in ACS patients. Assessing peritraumatic distress after ACS with the PDI may be useful for initiating early intervention against PTSD symptoms.

Relationship between NIH stroke symptoms and post-traumatic stress disorder in patients evaluated for transient ischemic attack/stroke

OBJECTIVE

Post-traumatic stress disorder (PTSD) can develop after a life-threatening medical event. According to the enduring somatic treat (EST) model, internal somatic cues (e.g., rapid heart rate) may contribute to symptoms of stroke/TIA-induced PTSD. To address this possibility, the present study tested the association of stroke-induced disability with PTSD symptoms in patients treated for stroke or transient ischemic attack (TIA).

METHOD

Participants (n = 300) were drawn from an observational cohort study examining PTSD symptoms in patients admitted to the NewYork Presbyterian Hospital between 2015 and 2017 for a stroke/TIA. Patients self-reported acute stress symptoms in-person approximately 3 days post-stroke/TIA and PTSD symptoms via telephone one month later. Severity of stroke symptoms (i.e., stroke disability) was evaluated using the NIH Stroke Scale prior to hospital discharge.

RESULTS

Stroke disability had a significant, positive association with acute stress symptoms early post-stroke/TIA, B = 0.46, se = 0.15, p = .002, and with PTSD symptoms one month later, B = 0.56, se = 0.19, p = .003.

CONCLUSIONS

Stroke disability is positively associated with both acute distress and PTSD symptoms one month later following a stroke/TIA, supporting the hypothesis that internal somatic symptoms contribute to the development stroke/TIA-induced PTSD symptoms.

Neurological Disorders and Risk of Arrhythmia

Neurological disorders including depression, anxiety, post-traumatic stress disorder (PTSD), schizophrenia, autism and epilepsy are associated with an increased incidence of cardiovascular disorders and susceptibility to heart failure. The underlying molecular mechanisms that link neurological disorders and adverse cardiac function are poorly understood. Further, a lack of progress is likely due to a paucity of studies that investigate the relationship between neurological disorders and cardiac electrical activity in health and disease. Therefore, there is an important need to understand the spatiotemporal behavior of neurocardiac mechanisms. This can be advanced through the identification and validation of neurological and cardiac signaling pathways that may be adversely regulated. In this review we highlight how dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis, autonomic nervous system (ANS) activity and inflammation, predispose to psychiatric disorders and cardiac dysfunction. Moreover, antipsychotic and antidepressant medications increase the risk for adverse cardiac events, mostly through the block of the human ether-a-go-go-related gene (hERG), which plays a critical role in cardiac repolarization. Therefore, understanding how neurological disorders lead to adverse cardiac ion channel remodeling is likely to have significant implications for the development of effective therapeutic interventions and helps improve the rational development of targeted therapeutics with significant clinical implications.

Medications as Traumatic Reminders in Patients With Stroke/Transient Ischemic Attack-Induced Posttraumatic Stress Disorder

BACKGROUND AND PURPOSE

Posttraumatic stress disorder (PTSD) symptoms are common after stroke/transient ischemic attack (TIA) and have been associated with medication nonadherence, potentially because medications serve as traumatic reminders of the prior stroke/TIA. This study examined associations between stroke/TIA-induced PTSD and aversive cognitions toward preventive medications.

METHODS

We enrolled a cohort of patients presenting to the emergency department with suspected stroke/TIA. One month posthospitalization, we assessed PTSD symptoms specific to the index stroke/TIA using the PTSD checklist specific and asked patients how often (1) did thinking about your stroke medication make you feel nervous or anxious?; (2) did thinking about your stroke medication make you think about your risk for future strokes?; and (3) did you skip or avoid taking your stroke medication so you would not have to think about your stroke? Logistic regression models tested the association between PTSD symptoms and each aversive cognition, adjusting for age, sex, ethnicity, and depression.

RESULTS

Among 408 included patients, 11.0% had elevated PTSD symptoms. These patients were more likely to report that thinking about their stroke medication made them feel nervous or anxious (37.8% versus 9.9%, P<0.001) that thinking about their stroke medication made them think about their risk for future stroke/TIA (60.0% versus 24.0%, P<0.001), and that they skipped or avoided their stroke medication to not think about their prior stroke/TIA (11.1% versus 2.2%, P=0.009). In adjusted analyses, higher PTSD checklist specific scores were associated with increased nervousness/anxiety (odds ratio, 1.33 [95% CI, 1.18-1.50], P<0.001) and thoughts of future stroke (odds ratio, 1.27 [95% CI, 1.14-1.41], P<0.001), with a trend toward significance for skipping medications to avoid reminders of stroke (odds ratio, 1.20 [95% CI, 0.99-1.44], P=0.06).

CONCLUSIONS

Medications may serve as traumatic reminders after stroke/TIA-induced PTSD, potentially leading to medication nonadherence.

Posttraumatic Stress Disorder, Depression, Anxiety, and Persistence of Methotrexate and TNF Inhibitors in Patients with Rheumatoid Arthritis

OBJECTIVE

To examine the relationship of posttraumatic stress disorder (PTSD) with earlier treatment discontinuation and medication adherence in US veterans with rheumatoid arthritis (RA).

METHODS

Veterans Affairs (VA) administrative data (2005-2014) were used to define unique dispensing episodes of methotrexate (MTX) and tumor necrosis factor inhibitors (TNFi) for veterans with RA. Diagnosis codes were used to categorize patients into mutually exclusive groups: PTSD (with/without depression/anxiety), depression/anxiety without PTSD, and neither psychiatric diagnosis. Multivariable Cox proportional hazards models were used to evaluate associations between psychiatric diagnoses and time to disease-modifying antirheumatic drug discontinuation (lapse in refill >90 days). Multivariable logistic regression was used to examine associations of diagnoses with medication nonadherence (proportion of days covered <0.8).

RESULTS

There were 15 081 dispensing episodes of MTX and 8412 dispensing episodes of TNFi. PTSD was independently associated with a greater likelihood of earlier discontinuation of both MTX (hazard ratio [HR] 1.15 [1.10-1.21]) and TNFi (HR 1.20 [1.13-1.28]). Depression/anxiety had a comparable risk of discontinuation for both MTX (HR 1.14 [1.10-1.19]) and TNFi (HR 1.16 [1.10-1.22]). Depression/anxiety, but not PTSD, was associated with higher odds of MTX (odds ratio [OR] 1.12 [1.03-1.22]) and TNFi (OR 1.14 [1.02-1.27]) nonadherence.

CONCLUSION

Veterans with RA and comorbid PTSD, depression, or anxiety had poor persistence of MTX and TNFi therapies. These results suggest that earlier discontinuation and low adherence to therapy among patients with RA with these psychiatric comorbidities may contribute to worse disease outcomes. Mechanisms by which these comorbidities contribute to lower adherence deserve further investigation and may lead to targeted interventions to improve disease outcomes.

Post-traumatic stress disorder symptoms after respiratory insufficiency in patients with myasthenia gravis

To explore posttraumatic stress disorder symptoms (PTSD) after respiratory insufficiency in patients with myasthenia gravis (MG). The investigation was made with 134 adult patients with MG, after respiratory insufficiency, between January 2012 and January 2016 and had a return visit after one year. 134 patients finished this study and 69 patients (51.5%) had PTSD. Anxiety (HADS-A ≥ 8, HADS: Hospital Anxiety and Depression Scale) (OR 2.585,95% CI 1.102-6.061, p = 0.029), and depression (HADS-D ≥ 8) (OR 3.200, 95% CI 1.395-7.342, p = 0.006) were associated with greater probabilities of screening positive for PTSD. Gender, age, intubation, yearly income, marriage, inability to work, number of respiratory insufficiency episodes, education level, Mini-mental state examination (MMSE) (>20), ICU stays, having insurance, and MG-activities of daily living (ADL) (<9) were not significant predictors for PTSD. One year after a respiratory insufficiency episode, patients with PTSD experienced worse anxiety (p = 0.035), depressive disorder (p < 0.001), and 36-Item Short-Form Health Survey (SF-36) showed physical functioning (p = 0.042), role-physical (p = 0.013), social functioning (p = 0.040), and emotional-role (p = 0.034). But there were no differences in ADL, bodily pain, general health and vitality. PTSD in patients with MG is common after a respiratory insufficiency episode; anxiety and depression were both associated with greater probabilities of screening positive for PTSD.

Predictors of posttraumatic stress following transient ischemic attack: An observational cohort study

OBJECTIVE

Transient ischemic attack (TIA) has been reported to be frequently followed by symptoms of post-TIA posttraumatic stress disorder (post-TIA PTSD). Risk factors for post-TIA PTSD remain largely unknown. We aimed to identify predictors of post-TIA PTSD development to enable post-TIA PTSD risk assessment and inform future development of treatment and prevention interventions.

METHOD

TIA patients were examined twice for this observational cohort study. Symptoms of post-TIA PTSD, depression and anxiety were assessed shortly after TIA during in-hospital stay (T1) and three months after TIA (T2). The impact of known general PTSD risk factors (psychiatric history, peritraumatic dissociation, social support), psychological resilience factors (sense of coherence, mindfulness, attachment style) and TIA characteristics (affected circulatory territory, symptom type and duration) at T1 on post-TIA PTSD symptom severity at T2 was tested using hierarchical multiple linear regression.

RESULTS

Sixty-one patients (83.6%) completed the study at T2. Fifteen patients (24.6%) were classified as post-TIA PTSD⊕ at T2. In multiple linear regression analysis, age, sex, psychiatric history, peritraumatic dissociation and social support together explained 39.9% of variance of post-TIA posttraumatic stress symptom severity. Sense of coherence and mindfulness explained further 17.8% of variance. Clinical TIA characteristics were not associated with post-TIA PTSD.

CONCLUSIONS

Post-TIA PTSD is a common phenomenon. General PTSD risk factors can be applied for post-TIA PTSD risk assessment. Sense of coherence and mindfulness are promising target variables for post-TIA PTSD treatment and prevention interventions.

Neuropsychiatric issues after stroke: Clinical significance and therapeutic implications

A spectrum of neuropsychiatric disorders is a common complication from stroke. Neuropsychiatric disorders after stroke have negative effects on functional recovery, increasing the rate of mortality and disability of stroke survivors. Given the vital significance of maintaining physical and mental health in stroke patients, neuropsychiatric issues after stroke have raised concerns by clinicians and researchers. This mini-review focuses on the most common non-cognitive functional neuropsychiatric disorders seen after stroke, including depressive disorders, anxiety disorders, post-traumatic stress disorder, psychosis, and psychotic disorders. For each condition, the clinical performance, epidemiology, identification of the therapeutic implication, and strategies are reviewed and discussed; the main opinions and perspectives presented here are based on the latest controlled studies, meta-analysis, or updated systematic reviews. In the absence of data from controlled studies, consensus recommendations were provided accordingly.

Unmet Need for Social and Emotional Support and Lack of Recalled Screening Is Associated with Depression in the Long-Term Course After Stroke

Purpose

Details on adequate care and prevalence of depression in long-term stroke aftercare are limited. We aimed to determine long-term depression rates after stroke and to test for an association between depression and inadequate screening, socio-economic complications and lack of sub-optimal care.

Patients and Methods

In this cross-sectional study, 57 patients were re-invited into the clinic 2-3 years after stroke. Patients were interviewed about recalled screening concerning depression and unmet needs. Depression, the patient's social situation, and confounders were assessed by standardized scores.

Results

In our study, 20% (n = 11) of patients were classified as depressed by the HDRS-17 score result. However, only 36% of all patients recalled to have been previously screened for depression and only 43% of those patients also recalled out-patient screening. Patients classified as depressed reported significantly lower recalled screening rates (9% vs 43%; p = 0.036) and higher rates of self-reported unmet need with emotional problems (72% vs 18%; p < 0.001). Depression in our study was further associated with a worse socio-economic situation, fewer social contacts, unmet needs with regard to emotional problems and higher rates of recommendations to apply for additional social support.

Conclusion

Our data suggest that systematic out-patient screening for depression is lacking in stroke aftercare. Furthermore, the high rate of unmet emotional needs, the poor socio-economic situation and the higher rates of recommendations for social counselling and application for benefits suggest an undersupply of care in the out-patient setting that is more prominent in patients with depression and warrants further studies to investigate the underlying causes.

Interventions for posttraumatic stress disorder symptoms induced by medical events: A systematic review

OBJECTIVE

Medical events such as myocardial infarction and cancer diagnosis can induce symptoms of posttraumatic stress disorder (PTSD). The optimal treatment of PTSD symptoms in this context is unknown.

METHODS

A literature search of 6 biomedical electronic databases was conducted from database inception to November 2018. Studies were eligible if they used a randomized design and evaluated the effect of treatments on medical event-induced PTSD symptoms in adults. A random effects model was used to pool data when two or more comparable studies were available.

RESULTS

Six trials met full inclusion criteria. Studies ranged in size from 21 to 81 patients, and included patients with PTSD induced by cardiac events, cancer, HIV, multiple sclerosis, and stem cell transplantation. All trials assessed psychological interventions. Two trials comparing a form of exposure-based cognitive behavioral therapy (CBT) with assessment-only control found that CBT resulted in lower PTSD symptoms [Hedges's g = -0.47, (95% CI -0.82 - -0.12), p = .009]. A third trial compared imaginal exposure (another form of exposure-based CBT) with an attention control and found a trend toward reduced PTSD symptoms. Three trials compared eye movement desensitization and reprocessing (EMDR) with active psychological treatments (imaginal exposure, conventional CBT, and relaxation therapy), and found that EMDR was more effective.

CONCLUSION

CBT and EMDR may be promising approaches to reducing PTSD symptoms due to medical events. However, additional trials are needed in this patient population.

Stressing Out About the Heart: A Narrative Review of the Role of Psychological Stress in Acute Cardiovascular Events

OBJECTIVES

Survivors of acute cardiovascular disease (CVD) events, such as acute coronary syndrome (ACS) and stroke, may experience significant psychological distress during and following the acute event. Long-term adverse effects may follow, including the development of posttraumatic stress disorder (PTSD), increased overall all-cause mortality, and recurrent cardiac events. The goal of this concepts paper is to describe and summarize the rates of adverse psychological outcomes, such as PTSD, following cardiovascular emergencies, to review how these psychological factors are associated with increased risk of future events and long-term health and to provide a theoretical framework for future work.

METHODS

A panel of two board-certified emergency physicians, one with a doctorate in experimental psychology, along with one PhD clinical psychologist with expertise in psychoneuroendocrinology were co-authors involved in the paper. Each author used various search strategies (e.g., PubMed, Psycinfo, Cochrane, and Google Scholar) for primary research and reviewed articles related to their section. The references were reviewed and evaluated for relevancy and included based on review by the lead authors RESULTS: A meta-analysis of 24 studies (N > 2,300) found the prevalence of ACS-induced PTSD at nearly 12%, while a meta-analysis of nine studies (N = 1,138) found that 25% of survivors of transient ischemic attack and stroke report PTSD symptoms. The presence of PTSD doubles 3-year risk of CVD/mortality risk in ACS survivors. Cardiac patients treated during periods of ED overcrowding, hallway care, and perceived poor clinician-patient communication appear at greater risk for subsequent PTSD.

CONCLUSIONS

Psychological stress is often present in patients undergoing evaluation for acute CVD events. Understanding such associations provides a foundation to appreciate the potential contribution of psychological variables on acute and long-term cardiovascular recovery, while also stimulating future areas of research and discovery.

The Association Among Medication Beliefs, Perception of Illness and Medication Adherence in Ischemic Stroke Patients: A Cross-Sectional Study in China

PURPOSE

To examine the association and the mediating effect among medication beliefs, perception of illness, and medication adherence in ischemic stroke patients.

PATIENTS AND METHODS

This is a cross-sectional study, 306 ischemic stroke patients recruited from The Second Affiliated Hospital of Harbin Medical University, China between June 2018 and October 2018. The Beliefs about Medications Questionnaire (BMQ) was used to assess a patient's beliefs about medication. The Brief Illness Perceptions Questionnaire (BIPQ) was used to rapidly determine the cognitive and emotional representation of ischemic stroke. Self-reported adherence was assessed using the Medication Adherence Report Scale (MARS). Logistic regression analysis, Pearson correlations, and mediation analysis were used to evaluate the association and mediating effects among medication beliefs, perception of illness, and medication adherence.

RESULTS

Overall, 220 (65.48%) participants were non-adherent to their ischemic stroke medications. Non-adherent patients had greater stroke severity (p = 0.031) compared to adherent patients. After adjusting for demographic characteristics, specific concern (odds ratio [OR]: 0.652, 95% confidence interval [CI]: 0.431 to 0.987, p-value [P] = 0.043), and the perception of illness (overall score) (OR: 0.964, 95% CI: 0.944 to 0.985, P = 0.001) were significantly associated with medication adherence in ischemic stroke patients. The mediation analysis showed the significant indirect effects of specific concern, general overuse, and general harm. It suggested that some impacts of medication beliefs have been mediated on medication adherence.

CONCLUSION

Perceived concern about adverse effects of medicines and perception of illness have an influential impact on self-reported medication adherence in ischemic stroke patients. To enhance adherence, patients' beliefs about medication and perceptions of their disease should be reconsidered. Future work should investigate interventions to influence patient adherence by addressing concerns about their ischemic stroke medications and the perception of the disease.

Incidence and predictors of post-traumatic stress symptoms in a cohort of patients with intracerebral hemorrhage

OBJECTIVES

Examine the incidence and predictors of PTSD symptoms in a cohort of patients with ICH.

PATIENTS AND METHODS

This study uses a prospective cohort of 108 patients with complete follow-up data including a questionnaire regarding stress symptoms (PCL-S: PTSD checklist specific for a stressor) at 3, 6, and 12 months.

RESULTS

The incidence of novel stress symptoms following ICH was approximately 6.5%. Age was negatively associated with PTSD symptoms with only trend-level significance (3 months: OR = 0.83, p = 0.087; 6 months: OR = 0.70, p = 0.015; 12 months: OR = 0.88, p =  0.087). Gender did not affect PTSD symptom development, (t = 1.34, p =  0.18). Pre-morbid functioning, initial stroke prognosis, total number of complications, and length of hospital/ICU stay were not associated with PTSD symptoms; however, each was significantly correlated with poorer functional outcomes. Yet, poorer functional outcomes were observed in those with higher reports of PTSD symptoms (r = 0.24, p = 0.01).

CONCLUSION

Functional outcomes in ICH are correlated with PTSD symptoms, however the mechanism and relationship are difficult to elucidate. Further research is needed to determine possible mechanisms by which a stroke patient may develop PTSD.

The Impact of Cardiac-induced Post-traumatic Stress Disorder Symptoms on Cardiovascular Outcomes: Design and Rationale of the Prospective Observational Reactions to Acute Care and Hospitalizations (ReACH) Study

Aims:

As many as 1 in 8 acute coronary syndrome (ACS) patients develop posttraumatic stress disorder (PTSD) due to the ACS, and ACS-induced PTSD may increase secondary cardiovascular disease (CVD) risk. However, prior studies have been small and underpowered to test plausible behavioral or biological mechanisms of the hypothesized PTSD-secondary CVD risk association. In this paper, we describe the design and methods of a large prospective observational cohort study to estimate the prognostic significance of ACS-induced PTSD, mechanisms for its association with CVD risk, and emergency department (ED) factors that may increase PTSD risk, in a cohort of patients evaluated for acute coronary syndrome (ACS) in the ED of a large, urban academic medical center.

Methods:

The Reactions to Acute Care and Hospitalization (ReACH) study follows 1,741 racially, ethnically, and socioeconomically diverse patients initially presenting to the ED with ACS symptoms. Psychosocial factors are assessed at baseline. Medication adherence is monitored by electronic pill bottle (eCAP). Participants are contacted by phone at 1-, 6-, and 12-months post-hospitalization to assess PTSD symptoms, hospital readmission, and recurrent CVD events/mortality (proactively searched and confirmed by medical records).

Conclusion:

This study will provide the most accurate estimates to date of PTSD’s association with recurrent CVD events and mortality and will test whether medication adherence mediates that association. Further, it will provide estimates of the contribution of ED and hospital factors to PTSD risk in ACS patients. If our hypotheses are supported, we will have identified PTSD as a novel target for secondary risk reduction.

Bringing close others to the emergency department for an acute coronary event is associated with increased patient perception of threat

OBJECTIVE

Relationship quality is one of the most consistent psychosocial predictors of physical and mental health. Yet, little research examines relationship types or support within the immediate context of acute health events. We tested the unexplored role that close others play in patients' experience of threat during evaluation for acute coronary syndrome (ACS) in the Emergency Department (ED), as well as the indirect effect of close others on ACS-induced posttraumatic stress disorder (PTSD).

METHOD

Participants were 871 patients evaluated for ACS at an urban academic ED (60.86 years old; 54.08% male; 56.37% Hispanic, 19.86% Black, 16.65% White). Threat perceptions were assessed in-ED and median 3 days later. ACS-induced PTSD was assessed median 41 days later using the PTSD checklist cued to a specific stressor. Non-overlapping categories were created representing close others in the ED (i.e., spouse/significant other, child), non-close others (e.g., neighbor), or no one.

RESULTS

Patients who brought close others recalled experiencing greater threat in the ED: vs. no one, b = 0.11, p = .072; vs. non-close others, b = 0.16, p = .030. There was no direct effect of close others on ACS-induced PTSD; however, recalled threat mediated the effect of close others on development of ACS-induced PTSD, ps < .05.

CONCLUSIONS

Close others were associated with recalling greater threat during ED evaluation, which predicted ACS-induced PTSD. ACS-induced PTSD is associated with medication nonadherence, event recurrence, and mortality, highlighting the need to develop a greater understanding of the impact stressful medical environments have on patients and close others.

A challenge for psychocardiology: Addressing the causes and consequences of patients' perceptions of enduring somatic threat

The enduring somatic threat (EST) model of posttraumatic stress disorder (PTSD) due to life-threatening medical events suggests that PTSD-like symptoms represent patients' sensitization to cues of ongoing threat in the body. In this article, we review research on the prevalence and consequences of such reactions in cardiovascular disease patients, discuss early tests of the EST model, and then report a new test of the EST model in 143 patients enrolled during their first acute coronary syndrome (ACS; i.e., non-ST elevation myocardial infarction or unstable angina-colloquially, "heart attack"). Invasive coronary revascularization procedures are commonly used to reduce secondary ACS risk and may reduce patients' EST, as revascularized patients often report being "cured." We assessed ACS patients' initial threat perceptions during emergency department (ED) evaluation and followed them for 1 month for PTSD symptoms (specific for ACS, by telephone). We compared PTSD symptoms in participants who were revascularized (n = 65), catheterized but not revascularized (n = 35), and medically managed (n = 43). PTSD symptoms were lower for revascularized versus medically managed participants (B = -5.32, 95% confidence interval [-9.77, -0.87]), t(98.19) = -2.37, p = .020. In a multiple regression model adjusted for clinical and psychosocial covariates, the interaction of threat perception in the ED and ACS management group was significant (greater ED threat predicted greater 1-month PTSD symptoms only in medically managed participants). These findings offer further support for the EST model and suggest that psychological interventions to preempt patients' development of EST should be considered in the hospital.

Identifying targets for cardiovascular medication adherence interventions through latent class analysis

OBJECTIVE

Reasons for nonadherence to cardiovascular medications vary widely between individuals. Yet, adherence interventions are often uniformly applied, limiting their effectiveness. This study employed latent class analysis (LCA) to identify multidimensional profiles of reasons for nonadherence to cardiovascular medications.

METHOD

Participants (N = 137; MAge = 58.8, SDAge = 11.8) were drawn from an observational study of the impact of cardiac-induced posttraumatic stress disorder (PTSD) on cardiac medication adherence in patients presenting to the emergency department with a suspected acute coronary syndrome. Demographics and depressive symptoms were assessed at baseline. Extent of nonadherence to cardiovascular medications, reasons for nonadherence, and PTSD symptoms were assessed 1 month after discharge.

RESULTS

LCA identified 3 classes of reasons for medication nonadherence: capacity (related to routine or forgetting; approximately 45% of the sample), capacity + motivation (related to routine/forgetting plus informational or psychological barriers; approximately 14% of the sample), and no clear reasons (low probability of endorsing any items; approximately 41% of the sample). Participants reporting greater nonadherence were more likely to be in the capacity + motivation or no clear reasons classes compared with the capacity class. Participants endorsing higher PTSD severity were more likely to be in the capacity + motivation or capacity classes compared with the no clear reasons class.

CONCLUSIONS

Three distinct classes of reasons for nonadherence were identified, suggesting opportunities for tailored interventions: capacity, capacity + motivation, and no clear reasons. These preliminary findings, if replicated, could aid identification of patients at risk for greater extent of medication nonadherence and inform tailored interventions to improve adherence.
