Subarachnoid hemorrhage as a psychological trauma

Post-Intensive Care Syndrome in Neurocritical Care Patients

Post-intensive care syndrome (PICS) refers to unintended consequences of critical care that manifest as new or worsening impairments in physical functioning, cognitive ability, or mental health. As intensive care unit (ICU) survival continues to improve, PICS is becoming increasingly recognized as a public health problem. Studies that focus on PICS have typically excluded patients with acute brain injuries and chronic neurodegenerative problems. However, patients who require neurocritical care undoubtedly suffer from impairments that overlap substantially with those encompassed by PICS. A major challenge is to distinguish between impairments related to brain injury and those that occur as a consequence of critical care. The general principles for the prevention and management of PICS and multidomain impairments in patients with moderate and severe neurological injuries are similar including the ICU liberation bundle, multidisciplinary team-based care throughout the continuum of care, and increasing awareness regarding the challenges of critical care survivorship among patients, families, and multidisciplinary team members. An extension of this concept, PICS-Family (PICS-F) refers to the mental health consequences of the intensive care experience for families and loved ones of ICU survivors. A dyadic approach to ICU survivorship with an emphasis on recognizing families and caregivers that may be at risk of developing PICS-F after neurocritical care illness can help improve outcomes for ICU survivors. In this review, we will summarize our current understanding of PICS and PICS-F, emerging literature on PICS in severe acute brain injury, strategies for preventing and treating PICS, and share our recommendations for future directions.

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.

The endogenous neuropeptide calcitonin gene-related peptide after spontaneous subarachnoid hemorrhage–A potential psychoactive prognostic serum biomarker of pain-associated neuropsychological symptoms

Background

The pronociceptive neuromediator calcitonin gene-related peptide (CGRP) is associated with pain transmission and modulation. After spontaneous subarachnoid hemorrhage (sSAH), the vasodilatory CGRP is excessively released into cerebrospinal fluid (CSF) and serum and modulates psycho-behavioral function. In CSF, the hypersecretion of CGRP subacutely after good-grade sSAH was significantly correlated with an impaired health-related quality of life (hrQoL). Now, we prospectively analyzed the treatment-specific differences in the secretion of endogenous CGRP into serum after good-grade sSAH and its impact on hrQoL.

Methods

Twenty-six consecutive patients (f:m = 13:8; mean age 50.6 years) with good-grade sSAH were enrolled (drop out n = 5): n = 9 underwent endovascular aneurysm occlusion, n = 6 microsurgery, and n = 6 patients with perimesencephalic SAH received standardized intensive medical care. Plasma was drawn daily from day 1 to 10, at 3 weeks, and at the 6-month follow-up (FU). CGRP levels were determined with competitive enzyme immunoassay in duplicate serum samples. All patients underwent neuropsychological self-report assessment after the onset of sSAH (t₁: day 11–35) and at the FU (t₂).

Results

During the first 10 days, the mean CGRP levels in serum (0.470 ± 0.10 ng/ml) were significantly lower than the previously analyzed mean CGRP values in CSF (0.662 ± 0.173; p = 0.0001). The mean serum CGRP levels within the first 10 days did not differ significantly from the values at 3 weeks (p = 0.304). At 6 months, the mean serum CGRP value (0.429 ± 0.121 ng/ml) was significantly lower compared to 3 weeks (p = 0.010) and compared to the first 10 days (p = 0.026). Higher mean serum CGRP levels at 3 weeks (p = 0.001) and at 6 months (p = 0.005) correlated with a significantly poorer performance in the item pain, and, at 3 weeks, with a higher symptom burden regarding somatoform syndrome (p = 0.001) at t₂.

Conclusion

Our study reveals the first insight into the serum levels of endogenous CGRP in good-grade sSAH patients with regard to hrQoL. In serum, upregulated CGRP levels at 3 weeks and 6 months seem to be associated with a poorer mid-term hrQoL in terms of pain. In migraineurs, CGRP receptor antagonists have proven clinical efficacy. Our findings corroborate the potential capacity of CGRP in pain processing.

Delayed Leukoencephalopathy and Foreign Body Reaction After Endovascular Treatment in Patients With Intracranial Aneurysms and Aneurysmal Subarachnoid Hemorrhage-A Systematic Review of the Literature

Background: Delayed leukoencephalopathy and foreign body reaction are rare complications after endovascular treatment of intracranial aneurysms. However, cases are increasingly being described, given the rising case numbers and complexity.

Methods: Clinical presentation, differentials, diagnostics, treatment, and formerly published data were reviewed in light of available cases. A systematic search of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

Results: This article provides an extensive literature review of previously described cases, and discusses the causes and management of this rare and delayed complication by referring to 17 articles on this topic, with a total of 50 cases with sufficient data in the literature. Furthermore, we present the case of a 53-year-old female patient with subarachnoid hemorrhage from a large anterior communicating artery aneurysm with tortuous cervical vessels who was treated with endovascular coiling and has suffered delayed leukoencephalopathy 6 weeks after discharge. Diagnostics, treatment, and clinical course of this rare complication are presented on this case and based on formerly published literature. The patient timely recovered under high dose corticosteroid treatment and follow up MRI showed almost complete remission of the described lesions within 10 days in accordance with previously published data.

Conclusion: Foreign body reaction might result in delayed leukoencephalopathy, especially following complex endovascular aneurysm treatment. Early high dose followed by low dose ongoing corticosteroid treatment might result in timely remission.

Auditory outcome following aneurysmal subarachnoid haemorrhage

Auditory deficits are increasingly recognised following aneurysmal subarachnoid haemorrhage (aSAH) and are thought to be of central rather than peripheral origin. Central hearing impairment, also known as auditory processing disorder (APD), often coexists with cognitive deficits and it is thought that APD has both auditory and cognitive elements. The aim of this study was to assess auditory outcome following aSAH and its relationship with cognition. A retrospective case-controlled study design was employed with aSAH cases and matched controls identified from the UK Biobank. Auditory and cognitive outcomes were assessed using the digit triplet test (DTT) and a test of psychomotor reaction time, respectively. Best DTT score was compared between cases and controls using the t-test. A regression-based mediation analysis was performed to assess whether cognition mediated auditory outcome. 270 aSAH patients with auditory outcomes were identified with an average follow-up of 106 months. A matched control cohort of 1080 individuals was also identified. The aSAH cohort had significantly impaired best DTT scores compared to matched controls (p = 0.002). Cognition significantly mediated auditory outcome following aSAH, accounting for 9.8% of the hearing impairment after aSAH. In conclusion significant hearing impairment follows aSAH. The deficit is bilateral and non-progressive. There is a link with cognitive deficit, pointing to a central rather than peripheral source, in keeping with an auditory processing disorder. All aSAH patients should be asked about hearing difficulty at follow-up and when present it should be investigated with peripheral and central auditory assessments, as well as cognitive tests.

Behaviors of Concern after Acquired Brain Injury: The Role of Negative Emotion Recognition and Anger Misattribution

OBJECTIVE

Behavioral changes are common after acquired brain injury (ABI) and may be caused by social cognition impairments. We investigated whether impaired emotion recognition, specifically Negative Emotion Recognition (NER) and Anger Misattribution (AM), after ABI was related to behavioral problems, so-called Behaviors of Concern (BoC).

METHOD

The study included 139 participants with ABI and 129 healthy controls. BoC was measured using four scales of the Brock Adaptive Functioning Questionnaire (BAFQ): Impulsivity, Aggression, Social Monitoring, and Empathy. Both self-ratings and informant ratings of BoC were obtained. Emotion recognition was measured with the Ekman 60 Faces Test (FEEST). A NER score was composed of the summed scores on Anger, Disgust, Fear, and Sadness. An AM score was composed of the number of facial expressions wrongly recognized as Anger.

RESULTS

Total FEEST scores in ABI participants were significantly worse than in healthy controls. The effect size is moderate. Informants rated significantly more problems in Social Monitoring and Empathy than participants. Effect sizes were small. Scores on FEEST total, NER, and AM were significantly correlated to informant ratings of Social Monitoring. Correlations were weak to moderate.

CONCLUSIONS

Worse NER and more profound AM were related to more informant-rated problems in social monitoring. In addition, informants rated more problems in social monitoring and empathy than participants. This strongly suggests problems in self-awareness in ABI participants. Consequently, social cognition tests and informant ratings should be used in clinical practice to improve the detection and treatment of BoC after ABI.

Psychological distress after subarachnoid haemorrhage: A systematic review and meta-analysis

OBJECTIVE

Psychological distress is a common complication in patients after Subarachnoid haemorrhage (SAH) which often has significant impact on the prognosis. The objective of this study was to determine the pooled prevalence of anxiety symptoms and depressive symptoms in patients after SAH and identify relevant risk factors.

METHODS

The study adopted a systematic review and meta-analysis protocol. Multiple databases including EMBASE, Medline, PsychInfo, and Web of Science were searched for publications before 1st January 2020. Screening, data extraction, and quality assessment were undertaken following the PRISMA guidelines for preferred reporting of systematic reviews and meta-analysis. The random-effects model was used to calculate pooled prevalence rates. Meta-analysis was conducted using Comprehensive Meta-analysis software. The review protocol was registered on PROSPERO (CRD42020182594).

RESULTS

42 studies reporting anxiety symptoms and 64 studies reporting depressive symptoms were included. The pooled short term(<3 years) and long term(≥3 years) prevalence rates of anxiety symptoms were 31.4%(95% CI: 23.6%, 40.4%) and 40.4%(95% CI: 31.6%, 49.8%), respectively, whereas the pooled short term and long term prevalence rates of depressive symptoms were 25.2%(95%CI: 17.8%, 34.5%) and 35.8%(95%CI: 28.6%, 43.6%), respectively. Gender and pre-existing psychiatric conditions were identified as potential risk factors.

CONCLUSIONS

The high prevalence of anxiety symptoms and depressive symptoms after SAH highlights the need for appropriate assessment and management of psychological stress in patients after SAH. Further research is warranted to explore potential underlying mechanisms and to develop holistic interventions that incorporate understanding of both the biological and psychological impact of SAH.

Aneurysmal subarachnoid haemorrhage: effect of CRHR1 genotype on fatigue and depression

BACKGROUND

Emotional health disturbances are common after aneurysmal subarachnoid hemorrhage (aSAH) and their causes are largely unexplored. Corticotropin-releasing hormone receptor 1 (CRHR1) is a key factor in stress reactivity and development of mental health disturbances after adverse life-events.

METHODS

We explore the effect of CRHR1 genotype on mental health after aSAH in a retrospective cohort study. One hundred twenty-five patients have been assessed using EST-Q mental health questionnaire. Genotyping of CRHR1 single nucleotide polymorphisms (SNP-s) was performed (Rs7209436, Rs110402, Rs242924).

RESULTS

Fatigue was present in almost half of aSAH patients, depression and anxiety in one-third. There was a high prevalence of insomnia and panic complaints. Rs110402 minor allele decreased the risk of depression (OR = 0.25, p = 0.027 for homozygotes). Depression was present in 14% vs 41% in minor and major allele homozygotes, respectively. Rs110402, Rs242924 and Rs7209436 minor alleles and TAT-haplotype, formed by them, were protective against fatigue. After Bonferroni correction only the association of Rs110402 with fatigue remained statistically significant (OR = 0.21, p = 0.006 for minor allele homozygotes). Results remained statistically significant when adjusted for gender, admission state, age and time from aSAH. In multiple regression analysis occurrence of fatigue was dependent on anxiety, modified Rankin score and Rs110402 genotype (R² = 0.34, p <  0.001).

CONCLUSIONS

CRHR1 minor genotype was associated with a lower risk of fatigue and depression after aSAH. Genetic predisposition to mental health disturbances associated with negative life-events could be a risk factor for fatigue and depression after aSAH and selected patients might benefit from advanced counselling in the recovery phase.

Pre-traumatic conditions can influence cortisol levels before and after a brain injury

OBJECTIVE

Satisfactory anabolic reactions, including the activation of the hypothalamic-pituitary-adrenal (HPA) axis, are essential following severe traumatic brain injury (TBI) and aneurysmal subarachnoid hemorrhage (SAH). Many factors may influence this activation. This study aimed to investigate whether individuals who reported chronic diseases, psychosocial afflictions, or stressful events before a severe brain injury display a different pattern regarding cortisol levels retrospectively and up to three months compared with those who did not report stressful experiences.

MATERIALS AND METHODS

Fifty-five patients aged 16-68 years who were admitted to the neurointensive care unit (NICU) were included. Hair cortisol measurements offer a unique opportunity to monitor cortisol levels retrospectively and after the trauma. Hair strands were collected as soon as possible after admission to the NICU and every month until three months after the injury/insult. The participants/relatives were asked about stressful events, psychosocial afflictions and recent and chronic diseases.

RESULTS

The group who reported chronic diseases and/or stressful events before the brain injury had more than twice as high median hair cortisol levels before the brain injury compared with those who did not report stress, but the difference was not statistically significant (P = .12). Those who reported stress before the brain injury had statistically significantly lower hair cortisol values after the brain injury and they remained until three months after the injury.

CONCLUSIONS

Stressful events and/or chronic disease before brain injury might affect mobilization of adequate stress reactions following the trauma. However, the large variability in cortisol levels in these patients does not allow firm conclusions and more studies are needed.

Depression after Subarachnoid Hemorrhage: A Systematic Review

Background and Purpose

Depression is common and debilitating illness accompanying many neurological disorders including non-traumatic subarachnoid hemorrhage (SAH). The aim of this systematic review was to identify and critically appraise all published studies that have reported the frequency, severity and time course of depression after SAH, the factors associated with its development and the impact of depression on patients’ quality of life after SAH.

Methods

The PubMed database was searched for studies published in English that recruited at least 40 patients (>18 years old) after SAH who were also diagnosed with depression.

Results

Altogether 55 studies covering 6,327 patients met study entry criteria. The frequency of depression ranged from 0% to 61.7%, with a weighted proportion of 28.1%. Depression remained common even several years after the index SAH. Depression after SAH was associated with female sex, premorbid depression, anxiety, substance use disorders or any psychiatric disorders, and coping styles. Comorbid cognitive impairment, fatigue, and physical disability also increased the risk of depression. Aneurysmal SAH and infarction may be related to depression as well. Depression reduces the quality of life and life satisfaction in patients after SAH.

Conclusions

Depression is common after SAH and seems to persist. Further research is needed to clarify its time course and identify the neuroendocrine and neurochemical factors and brain circuits associated with the development of post-SAH depression. Randomized controlled treatment trials targeting SAH-related depression are warranted.

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 post-aSAH syndrome: a self-reported cluster of symptoms in patients with aneurysmal subarachnoid hemorrhage

OBJECTIVE

Although many patients recover to a good functional outcome after aneurysmal subarachnoid hemorrhage (aSAH), residual symptoms are very common and may have a large impact on the patient's daily life. The particular cluster of residual symptoms after aSAH has not previously been described in detail and there is no validated questionnaire that covers the typical problems reported after aSAH. Many of the symptoms are similar to post-concussion syndrome, which often is evaluated with the Rivermead Post-Concussion Symptoms Questionnaire (RPQ). In the present study, the authors therefore performed an exploratory use of the RPQ as a template to describe post-aSAH syndrome.

METHODS

The RPQ was administered to 128 patients in the chronic phase after aSAH along with a battery of quality-of-life questionnaires. The patients also underwent a medical examination besides cognitive and physical testing. Based on their RPQ scores, patients were dichotomized into a "syndrome" group or "recovery" group.

RESULTS

A post-aSAH syndrome was seen in 33% of the patients and their symptom burden on all RPQ subscales was significantly higher than that of patients who had recovered on all RPQ subscales. The symptom cluster consisted mainly of fatigue, cognitive problems, and emotional problems. Physical problems were less frequently reported. Patients with post-aSAH syndrome scored significantly worse on mobility and pain scores, as well as on quality-of-life questionnaires. They also had significantly poorer scores on neuropsychological tests of verbal learning, verbal short- and long-term memory, psychomotor speed, and executive functions. Whereas 36% of the patients in the recovery group were able to return to their premorbid occupational status, this was true for only 1 patient in the syndrome group.

CONCLUSIONS

Approximately one-third of aSAH patients develop a post-aSAH syndrome. These patients struggle with fatigue and cognitive and emotional problems. Patients with post-aSAH syndrome report more pain and reduced quality of life compared to patients without this cluster of residual symptoms and have larger cognitive deficits. In this sample, patients with post-aSAH syndrome were almost invariably excluded from return to work. The RPQ is a simple questionnaire covering the specter of residual symptoms after aSAH. Being able to acknowledge these patients' complaints as a defined syndrome using the RPQ should help patients to accept and cope, thereby alleviating possible secondary distress produced.

Exploratory study of the course of posttraumatic stress disorder after aneurysmal subarachnoid hemorrhage

OBJECTIVE

Posttraumatic stress disorder (PTSD) occurs often in aneurysmal subarachnoid hemorrhage (aSAH) survivors, but how PTSD develops over time post-aSAH is still unclear. We examined the course of PTSD symptoms during the first year after aSAH.

METHOD

In this prospective cohort study, the Impact of Event Scale (IES) was applied in 128 patients 3, 6 and 12 months after aSAH. Multilevel modelling was used to assess changes in levels of PTSD symptoms over time and to explore if demographic characteristics, aSAH characteristics, level of education, cognitive functioning and neuroticism are associated to the course of PTSD symptoms.

RESULTS

Multilevel analyses showed at group level no differences in the average level of PTSD symptoms between 3, 6 of 12 months post-aSAH (p = 0.22). At individual level, changes in PTSD symptoms over time were present (X² (121) = 149.73 p = 0.04). None of the factors could explain the variance in change of PTSD symptoms over time.

CONCLUSIONS

The course of PTSD appears to differ between individuals after aSAH. We found no factors that explain these differences. There is not one optimal moment in time to assess PTSD. Therefore, it is important to assess PTSD at several time points after aSAH.

In Individuals Following Aneurysmal Subarachnoid Haemorrhage, Hair Cortisol Concentrations Are Higher and More Strongly Associated with Psychological Functioning and Sleep Complaints than in Healthy Controls

BACKGROUND

Following an aneurysmal subarachnoid haemorrhage (aSAH), many patients report persistent deficits in psychological functioning, characterised by high levels of stress and symptoms of depression, low life satisfaction, along with poor sleep. Such deficits have been associated with altered saliva and serum cortisol levels due to a dysregulation of hypothalamic-pituitary-adrenal axis activity (HPA-AA). However, hair cortisol concentrations (HCCs) have not been assessed in this population, although this method allows a long-term insight into cortisol values. Therefore, the objective of this study was to compare HCCs in aSAH patients and healthy controls and to examine how HCCs are associated with perceived stress, psychological functioning, and sleep complaints.

METHODS

In this cross-sectional study, data on depressive symptoms, hypochondriacal beliefs, life satisfaction, and sleep complaints were gathered in 15 aSAH patients and 17 healthy controls. HCCs of the previous 3 months were assessed.

RESULTS

aSAH patients had significantly higher HCCs than healthy controls. In aSAH patients, higher HCCs were significantly associated with increased depressive symptoms, hypochondriacal beliefs, lower life satisfaction, and increased sleep complaints. Such significant associations were not found in healthy controls.

CONCLUSIONS

Our findings indicate that a dysregulation of HPA-AA is associated with some of the long-term impairments in psychological functioning and sleep in aSAH survivors. While the direction of association remained unclear, a dysregulated HPA-AA may be causally linked with the maintenance of poor psychological functioning and poor sleep. The overall findings should be considered in the planning of long-term treatment aimed at improving psychological functioning and sleep in aSAH patients.

Peritraumatic distress fully mediates the relationship between posttraumatic stress symptoms preoperative and three months postoperative in patients undergoing spine surgery

Background: Growing evidence shows the significance of illness and surgical procedures as traumatizing stressors. Risk factors are widely investigated in various settings and samples, using numerous measures of posttraumatic stress and posttraumatic stress disorder (PTSD). While pretrauma psychological distress is acknowledged as an influential factor, peritraumatic experiences are controversially still being discussed as relevant to the development of PTSD. Objective: In a group of patients consecutively undergoing elective spine surgery (N = 89) in a German hospital, this longitudinal study addressed the question of how pretrauma PTSD symptoms and peritrauma distress interact with one another in regard to the amount of posttrauma symptoms of PTSD. Methods: Pre- and posttrauma symptoms of PTSD as well as peritrauma distress were assessed through questionnaires one week before, one week after or three months after surgery. Results: Even though all three variables showed significant correlations with one another, mediation analysis revealed that peritrauma distress fully mediated the relationship between pre- and posttrauma PTSD symptoms. Conclusions: These results add new insights to the controversial discussion on the role peritraumatic experiences play in the development of PTSD, especially in medical settings.

[Depression and depression-related disorders after a subarachnoid hemorrhage]

Psychiatric disorders often develop after subarachnoid hemorrhage (SAH); the most frequent of them are depression and depression-related disorders (anxiety, apathy, pathological fatigue, posttraumatic stress disorder, etc.). Both biological and psychological mechanisms may underlie the development of these disorders. Depression and depression-related disorders decrease patients' quality of life and prevent the full recovery after SAH. Identification and correction of these disorders should take a prominent place in the rehabilitation of post-SAH patients. More research is needed in this area.

Patient-reported outcome measures for patients with cerebral aneurysms acquired via social media: data from a large nationwide sample

Background

With greater survival rates, patient-reported outcome measures (PROMs) among survivors of ruptured cerebral aneurysm should be an increasing concern among neurointerventionalists. Prior studies were limited in scale and generalizability. Our study aims were to (1) evaluate the validity of cerebral aneurysm PROMs obtained from social media; (2) determine the persistence of PROMs over time; and (3) determine what PROMs still exist in those with no physical impairments.

Methods

By engaging national brain aneurysm support groups and using an online questionnaire modeled after the generic EQ-5D instrument, we asked respondents to classify their health in five dimensions including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using a 3-point Likert scale.

Results

In 2 months we received 604 responses from 46 states in the USA. Our cohort of ruptured aneurysm respondents reported PROMs similar to previously published series. Over time, headache and anxiety improved while depression, level of exercise, and return to work remained unchanged. We found that memory worsened after 2 years. Among those without any physical impairment, rates of 20.6%, 14.9%, 12.6%, and 23% were seen for significant headaches, significant memory loss, significant depression, and sense of life being negatively affected, respectively.

Conclusions

Despite this novel study design, we obtained results comparable to prior studies. These results suggest that many patients with ruptured cerebral aneurysms, regardless of whether they are >2 years after the event and/or free of physical impairment, struggle with a poor quality of life. The latency, scale, and low cost of this study design may accelerate future cerebral aneurysm PROM research.
