Assessment of co-morbidity of adult separation anxiety in patients with bipolar disorder

Obsessive-Compulsive Disorder as an Epiphenomenon of Comorbid Bipolar Disorder? An Updated Systematic Review

BACKGROUND

Bipolar disorder (BD) and obsessive-compulsive disorder (OCD) comorbidity is an emerging condition in psychiatry, with relevant nosological, clinical, and therapeutic implications.

METHODS

We updated our previous systematic review on epidemiology and standard diagnostic validators (including phenomenology, course of illness, heredity, biological markers, and treatment response) of BD-OCD. Relevant papers published until (and including) 15 October 2023 were identified by searching the electronic databases MEDLINE, Embase, PsychINFO, and Cochrane Library, according to the PRISMA statement (PROSPERO registration number, CRD42021267685).

RESULTS

We identified 38 new articles, which added to the previous 64 and raised the total to 102. The lifetime comorbidity prevalence ranged from 0.26 to 27.8% for BD and from 0.3 to 53.3% for OCD. The onset of the two disorders appears to be often overlapping, although the appearance of the primary disorder may influence the outcome. Compared to a single diagnosis, BD-OCD exhibited a distinct pattern of OC symptoms typically following an episodic course, occurring in up to 75% of cases (vs. 3%). Notably, these OC symptoms tended to worsen during depressive episodes (78%) and improve during manic or hypomanic episodes (64%). Similarly, a BD course appears to be chronic in individuals with BD-OCD in comparison to patients without. Additionally, individuals with BD-OCD comorbidity experienced more depressive episodes (mean of 8.9 ± 4.2) compared to those without comorbidity (mean of 4.1 ± 2.7).

CONCLUSIONS

We found a greater likelihood of antidepressant-induced manic/hypomanic episodes (60% vs. 4.1%), and mood stabilizers with antipsychotic add-ons emerging as a preferred treatment. In line with our previous work, BD-OCD comorbidity encompasses a condition of greater nosological and clinical complexity than individual disorders.

Impact of Childhood Trauma and Adult Separation Anxiety Disorder on Quality of Life in Individuals with Schizophrenia

Background

Childhood trauma and anxiety disorders are common in individuals with schizophrenia. This study aimed to investigate the effects of childhood trauma and adult separation anxiety disorder on the quality of life of individuals with schizophrenia.

Methods

This cross-sectional study included 111 individuals with schizophrenia and 85 control subjects. The separation anxiety symptom inventory (SASI), adult separation anxiety questionnaire (ASAQ), Positive and Negative Syndrome Scale (PANSS), childhood trauma questionnaire (CTQ), and World Health Organization quality of life questionnaire (WHOQoL-BREF) were administered to the participants.

Results

More individuals with schizophrenia than control subjects were unemployed and single (p<0.05). Individuals with schizophrenia scored significantly higher on the SASI, ASAQ, and CTQ (p<0.05), whereas the control subjects scored significantly higher on the WHOQoL-BREF (p<0.05). ASAQ scores had mild positive correlations with total PANSS and PANSS subscale scores, and moderate positive correlations with total CTQ, CTQ emotional subscale scores, and CTQ physical abuse subscale scores. A negative moderate correlation was found between ASAQ and total WHOQoL-BREF scores. Mediation analysis revealed that CTQ scores significantly affected total WHOQoL-BREF and ASAQ scores. The model pathway for ASAQ scores showed a significant direct and indirect effect of CTQ on the total WHOQoL-BREF scores.

Conclusion

Childhood trauma predicts adult separation anxiety disorder, which partially mediates the impact of childhood trauma on quality of life in individuals with schizophrenia. Therapeutic interventions for adult separation anxiety disorder in individuals with schizophrenia and a history of childhood trauma may help increase their quality of life.

Relationship Between Adult Separation Anxiety Disorder and Suicide in Patients with Bipolar Disorder

Life expectancy of patients with bipolar disorder (BD) is known to be shorter than the general population. Some of the premature deaths in these patients are attributed to unnatural causes such as suicide, accidents and homicides. Death due to suicide is 15 times more common in patients with GI compared to the general population. The present study aimed to investigate the comorbidity of Adult Separation Anxiety Disorder (ASAD) and the relationship between this comorbidity and suicide in patients with BD. A total of 138 outpatients with BD at remission between the ages of 18-65 years and 63 healthy controls were included in our study. All participants were administered a sociodemographic data form, Hamilton Depression Scale (HMDS), Young Mania Rating Scale (YMRS), Adult Separation Anxiety Questionnaire, and Structured Clinical Interview for Separation Anxiety Symptoms (ASAD-SCI). The age and gender of the participants did not differ significantly between the control group, the BD and BD+ASAD groups. The mean age of the participants was 42.3±11.9 years. When categorized according to gender, 42.3% of the participants were male and 57.7% were female. ASAD was detected in 46.3% of the participants. The suicide attempt rate was significantly higher in the BD and BD+ASAD groups than in the control group. The rate of suicide attempt was significantly higher in the BD+ASAD group than in the BB group. We demonstrated that the comorbidity of ASAD was associated with previous suicide attempts in patients with BD. Recognizing and treating ASAD in patients with BD may reduce suicide attempts in these patients.

Emotional and cognitive conflict resolution and disruptive mood dysregulation disorder in adolescent offspring of parents diagnosed with major depressive disorder, bipolar disorder, and matched healthy controls

AIMS

Children of parents with mood disorders have an elevated risk for various psychopathologies. In this study rate of psychopathologies among adolescent offspring of parents with major depressive (MDDoff) and bipolar disorder (BDoff), including disruptive mood dysregulation disorder (DMDD) along with the offspring ability to resolve cognitive and emotional conflicts were evaluated.

METHOD

12-16 years old children of parents with MDD (n = 31, children= 36), BP (n = 20, children = 26) and controls (n = 25, children = 28) were enrolled. Children and parents were evaluated by using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID); respectively. The parents completed the Child Behavior Checklist (CBCL)-dysregulation profile. The Stroop test-TBAG form and emotional Stroop test were given out to evaluate conflict resolution ability.

RESULTS

The most common diagnoses among the whole sample were attention deficit and hyperactivity, separation anxiety and oppositional defiant disorders. Five cases (5.5%) of lifetime DMDD were found (three from MDDoff, the rest from BDoff). Completion times for the Stroop test-TBAG form were ranked as: BDoff > MDDoff > Hoff. In the emotional Stroop test, the BDoff responded significantly later and had significantly reduced correct responses.

CONCLUSION

Rates of lifetime DMDD were similar in the MDDoff and BDoff groups. BDoff may experience greater difficulties in resolving cognitive and emotional conflicts.

Psychometric analysis of the adult separation anxiety symptom questionnaire: Item functioning and invariance across gender and time

The Adult Separation Anxiety Symptom Questionnaire (ASA-27) is the most widely used self-report assessment of adult separation anxiety (ASA). Despite its widespread use, relatively little is known about its psychometric properties, specifically whether it is unidimensional, its degree of precision (or information) across latent levels of ASA, the functioning of individual items in general and of DSM-derived versus non-DSM-derived items in particular, and whether the measure is invariant across gender and time. We addressed these issues in a sample of 509 adult women and 407 adult men from the local community participating in a longitudinal study of temperament and psychopathology in children. Two items from the ASA-27 were removed so that the measure met the item response theory (IRT) assumption of unidimensionality. Findings from a graded response model for categorical items suggested that the ASA-27 assesses ASA most reliably at moderate to high levels and that the DSM-derived items were more closely related to latent ASA than the non-DSM-derived items. Invariance tests employing single-factor confirmatory factor analysis models suggested that the measure is partially invariant across gender and time at the unique factor level, with fewer than 7% of parameters freed in both cases; this implies that the means and variances of the latent factors and differences in the observed responses are attributable to true differences in ASA. Future work should replicate these findings in a sample that includes individuals with a wider range of ASA severity and may consider removing additional items that provide little or redundant information.

Anxiety disorders anticipate the diagnosis of bipolar disorder in comorbid patients: Findings from an Italian tertiary clinic

BACKGROUND

Studies indicate bipolar disorder (BD) syndromal symptoms are commonly preceded by sub-syndromal BD symptoms, dysregulated sleep, irritability, and anxiety. We aimed to evaluate prevalence and clinical correlates of anxiety disorders (ADs) at BD onset in outpatients with versus without at least one AD at BD onset.

METHODS

246 bipolar spectrum outpatients, according to the text revision of the fourth edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM- IV-TR), attending Sacco University Hospital in Milan, were recruited and their onset and clinical features assessed retrospectively. Patients were stratified into those with versus without an AD at BD onset (w/A and wo/A), according to a semi-structured clinical interview to provide diagnoses according to (DSM- IV-TR).

RESULTS

29% of patients reported being w/A, among whom Panic Disorder (PD, in 55.6%) was the most frequent AD, and first AD occurred approximately 4 years before BD diagnosis. Patients w/A versus wo/A had higher (p < 0.05) rates of BDII and first mood episode being depression versus elevation (mania/hypomania), and lifetime rates of separation anxiety disorder, substance poly-abuse and benzodiazepine abuse. In contrast, patients wo/A had higher lifetime rates of alcohol and illicit drug use.

CONCLUSION

In this naturalistic sample, ADs, in particular PD, preceded BD in almost 1/3 of BD outpatients, and had distinctive clinical correlates. Further investigation into relationships between BD and AD at onset may enhance early BD diagnosis and treatment.

Prevalence and Associated Features of Anxiety Disorder Comorbidity in Bipolar Disorder: A Meta-Analysis and Meta-Regression Study

Objective: Bipolar disorder is highly comorbid with anxiety disorders, however current and lifetime comorbidity patterns of each anxiety disorder and their associated features are not well studied. Here, we aimed to conduct a meta-analysis and meta-regression study of current evidence. Method: We searched PubMed to access relevant articles published until September 2015, using the keywords "Bipolar disorder" or "Affective Psychosis" or "manic depressive" separately with "generalized anxiety," "panic disorder," "social phobia," "obsessive compulsive," and "anxiety." Variables for associated features and prevalence of anxiety disorders were carefully extracted. Results: Lifetime any anxiety disorder comorbidity in BD was 40.5%; panic disorder (PD) 18.1%, generalized anxiety disorder (GAD) 13.3%, social anxiety disorder (SAD) 13.5% and obsessive compulsive disorder (OCD) 9.7%. Current any anxiety disorder comorbidity in BD is 38.2%; GAD is 15.2%, PD 13.3%, SAD 11.7%, and OCD 9.9%. When studies reporting data about comorbidities in BDI or BDII were analyzed separately, lifetime any anxiety disorder comorbidity in BDI and BDII were 38% and 34%, PD was 15% and 15%, GAD was 14% and 16.6%, SAD was 8% and 13%, OCD was 8% and 10%, respectively. Current any DSM anxiety disorder comorbidity in BDI or BDII were 31% and 37%, PD was 9% and 13%, GAD was 8% and 12%, SAD was 7% and 11%, and OCD was 8% and 7%, respectively. The percentage of manic patients and age of onset of BD tended to have a significant impact on anxiety disorders. Percentage of BD I patients significantly decreased the prevalence of panic disorder and social anxiety disorder. A higher rate of substance use disorder was associated with greater BD-SAD comorbidity. History of psychotic features significantly affected current PD and GAD. Conclusions: Anxiety disorder comorbidity is high in BD with somewhat lower rates in BDI vs BDII. Age of onset, substance use disorders, and percentage of patients in a manic episode or with psychotic features influences anxiety disorder comorbidity.

Prevalence of current anxiety disorders in people with bipolar disorder during euthymia: a meta-analysis

BACKGROUND

Anxiety disorders are highly prevalent in people with bipolar disorder, but it is not clear how many have anxiety disorders even at times when they are free of major mood episodes. We aimed to establish what proportion of euthymic individuals with bipolar disorder meet diagnostic criteria for anxiety disorders.

METHOD

We performed a random-effects meta-analysis of prevalence rates of current DSM-III- and DSM-IV-defined anxiety disorders (panic disorder, agoraphobia, social anxiety disorder, generalized anxiety disorder, specific phobia, obsessive-compulsive disorder, post-traumatic stress disorder, and anxiety disorder not otherwise specified) in euthymic adults with bipolar disorder in studies published by 31 December 2015.

RESULTS

Across 10 samples with 2120 individuals with bipolar disorder, 34.7% met diagnostic criteria for one or more anxiety disorders during euthymia [95% confidence interval (CI) 23.9-45.5%]. Direct comparison of 189 euthymic individuals with bipolar disorder and 17 109 population controls across three studies showed a 4.6-fold increase (risk ratio 4.60, 95% CI 2.37-8.92, p < 0.001) in prevalence of anxiety disorders in those with bipolar disorder.

CONCLUSIONS

These findings suggest that anxiety disorders are common in people with bipolar disorder even when their mood is adequately controlled. Euthymic people with bipolar disorder should be routinely assessed for anxiety disorders and anxiety-focused treatment should be initiated if indicated.
