[PMID: 37993977 DOI: 10.1080/13854046.2023.2283937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 11/09/2023] [Indexed: 11/24/2023]
Abstract
Objective: Cognitive, mood, and behavioral changes are common among persons with epilepsy (PWE), resulting in a complex neuropsychological presentation. Women with epilepsy (WWE) represent a distinct cohort within the broader epilepsy population due to sex and gender-specific factors impacting epilepsy semiology and treatment. However, unique neuropsychological profiles among WWE have not been established. This narrative review aims to further define neuropsychological correlates in WWE and promote meaningful discussion related to enhancing the provision of neuropsychological care within this clinical population. Method: Current literature in PWE examining differences in cognitive function, mental health, and quality of life (QoL) between women and men was critically reviewed, emphasizing considerations for neuropsychological practice. Results: WWE demonstrate a preservation of verbal learning and memory compared to men both pre- and post-surgically, with sex-based, neurobiological mechanisms likely contributing to this association. WWE also have elevated risk for affective disorder psychopathology, suicidality, and traumatic experiences. Epidemiology related to psychotic and bipolar spectrum disorders is less clear, and findings are mixed regarding sex-specific behavioral side effects of antiseizure and psychotropic medication. Finally, hormonal and obstetric factors are highlighted as important contributors to neuropsychological symptoms in WWE, with elevated risk for low QoL and increased stigma associated with greater medical and psychiatric comorbidities compared to men. Conclusions: While emerging literature has begun to characterize the neuropsychological presentation of WWE, future research is needed to define sex and gender differences in neuropsychological sequalae among PWE to ensure consistency and quality of care for WWE.

Cichoń L, Janas-Kozik M, Chełmecka E, Wilczyński KM, Jelonek I, Rybakowski JK. Does the clinical picture of bipolar disorder in the pediatric population depend on sex? J Affect Disord 2024; 363:501-506. [PMID: 39029674 DOI: 10.1016/j.jad.2024.07.071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 07/02/2024] [Accepted: 07/14/2024] [Indexed: 07/21/2024]
Abstract
BACKGROUND In the current literature the influence of sex on the clinical presentation of the bipolar disorder (BD) in adults has been indicated. It was of the interest whether such a phenomenon is also present in the pediatric population. METHODS The authors collected retrospective clinical data in 288 patients hospitalized on the psychiatry ward aged 10-17 years; 80.2 % females and 19.8 % males. RESULTS No sex differences were observed in the age of onset, the time from the onset of symptoms to the diagnosis of BD, the number of symptoms during hospital stay, or family history of psychiatric disorder (U Mann-Whitney's p > 0.05). In males the most frequently recorded first episode of BD was mania or hypomania (51 %), and in females, a depressive episode (51 %). The main reason for the hospitalization in boys was episodes of mania (63 %), then mixed episodes (30 %), and depression (7 %). Whereas girls were most often hospitalized due to mixed episodes (52 %), less frequently depression (22 %), and mania (26 %). Co-morbid psychiatric disorders were found more often in boys than in girls (63 % vs 45 %; χ2p-value>0.05). The co-occurrence of the dissocial personality, borderline, tic disorders, pervasive developmental disorders and hyperkinetic disorders was different in both sexes. LIMITATIONS The main limitations of the study are the very high proportion of female subjects and the retrospective character of the study. CONCLUSIONS It seems that the clinical presentation of BD in the pediatric population can somewhat depend on the sex of the patients.

Abstract
Rapid-eye movement (REM) sleep deprivation (SD) can induce manic-like behaviors including hyperlocomotion. On the other hand, crocin (one of the main compounds of Crocus sativus L. or Saffron) may be beneficial in the improvement of mental and cognitive dysfunctions. Also, crocin can restore the deleterious effects of SD on mental and cognitive processes. In this study, we investigated the effect of REM SD on female rats' behaviors including depression- and anxiety-like behaviors, locomotion, pain perception, and obsessive-compulsive-like behavior, and also, the potential effect of crocin on REM SD effects. We used female rats because evidence on the role of REM SD in modulating psychological and behavioral functions of female (but not male) rats is limited. REM SD was induced for 14 days (6h/day), and crocin (25, 50, and 75 mg/kg) was injected intraperitoneally. Open field test, forced swim test, hot plate test, and marble burying test were used to assess rats' behaviors. The results showed REM SD-induced manic-like behavior (hyperlocomotion). Also, REM SD rats showed decreased anxiety- and depression-like behavior, pain subthreshold (the duration it takes for the rat to feel pain), and showed obsessive compulsive-like behavior. However, crocin at all doses partially or fully reversed REM SD-induced behavioral changes. In conclusion, our results suggested the possible comorbidity of OCD and REM SD-induced manic-like behavior in female rats or the potential role of REM SD in the etiology of OCD, although more studies are needed. In contrast, crocin can be a possible therapeutic choice for decreasing manic-like behaviors.

Sex Differences Among Older Adults With Bipolar Disorder: Results From the Global Aging & Geriatric Experiments in Bipolar Disorder (GAGE-BD) Project. Am J Geriatr Psychiatry 2024; 32:326-338.

Abstract
OBJECTIVE Sex-specific research in adult bipolar disorder (BD) is sparse and even more so among those with older age bipolar disorder (OABD). Knowledge about sex differences across the bipolar lifespan is urgently needed to target and improve treatment. To address this gap, the current study examined sex differences in the domains of clinical presentation, general functioning, and mood symptoms among individuals with OABD. METHODS This Global Aging & Geriatric Experiments in Bipolar Disorder (GAGE-BD) study used data from 19 international studies including BD patients aged ≥50 years (N = 1,185: 645 women, 540 men).A comparison of mood symptoms between women and men was conducted initially using two-tailed t tests and then accounting for systematic differences between the contributing cohorts by performing generalized linear mixed models (GLMMs). Associations between sex and other clinical characteristics were examined using GLMM including: age, BD subtype, rapid cycling, psychiatric hospitalization, lifetime psychiatric comorbidity, and physical health comorbidity, with study cohort as a random intercept. RESULTS Regarding depressive mood symptoms, women had higher scores on anxiety and hypochondriasis items. Female sex was associated with more psychiatric hospitalizations and male sex with lifetime substance abuse disorders. CONCLUSION Our findings show important clinical sex differences and provide support that older age women experience a more severe course of BD, with higher rates of psychiatric hospitalization. The reasons for this may be biological, psychological, or social. These differences as well as underlying mechanisms should be a focus for healthcare professionals and need to be studied further.

Abstract
Bipolar disorder (BD) is worldwide a prevalent mental illness and a leading risk factor for suicide. Over the past three decades, it has been discovered that sex differences exist throughout the entire panorama of BD, but the etiologic regions and mechanisms that generate such differences remain poorly characterized. Available evidence indicates that the dorsolateral prefrontal cortex (DLPFC), a critical region that controls higher-order cognitive processing and mood, exhibits biological disparities between male and female patients with psychiatric disorders, which are highly correlated with the co-occurrence of psychotic symptoms. This review addresses the sex differences in BD concerning epidemiology, cognitive impairments, clinical manifestations, neuroimaging, and laboratory abnormalities. It also provides strong evidence linking DLPFC to the etiopathogenesis of these sex differences. We emphasize the importance of identifying gene signatures using human brain transcriptomics, which can depict sexually different variations, explain sex-biased symptomatic features, and provide novel targets for sex-specific therapeutics.

Abstract
The aim of this study was to examine the parenting characteristics of young patients with bipolar disorder (BD) and explore the sex differences. The parental rearing pattern of young patients with BD was measured and compared with the healthy control of young adults. The EMBU scale was used to assess parental rearing patterns. Patients with BD reported significantly higher scores in the punishment and severity index, as well as of the rejection and denial index, but lower scores in the warmth & affectionate index in the paternal rearing pattern, compared with healthy controls. In addition, patients scored higher on the punishment and severity index and rejection and patterns index in maternal rearing patterns. More importantly, we found significant sex differences in maternal rearing patterns (pBonferroni < 0.05). Specifically, in the maternal rearing patterns, male patients had higher scores on the favoring index than male controls, whereas female patients had lower scores on the warmth & affectionate index than female controls. This study shows significant differences in parental rearing patterns between patients and control subjects. Male patients were overprotective by their mothers and female patients were overlooked by their mothers during upbringing.

Abstract
Introduction Bipolar Affective Disorder (BPAD) merits careful consideration within the medical and healthcare communities, researchers, and policymakers. This is due to its substantial disability burden, elevated prevalence of co-morbidities, heightened lifetime risk of suicidality, and a significant treatment gap. This article focuses on the lifetime and current prevalence, correlates, co-morbidities, associated disabilities, socio-economic impact, and treatment gap for BPAD in the adult population of the National Mental Health Survey (NMHS) 2016. Materials and Methods The NMHS 2016 was a nationally representative study conducted across 12 Indian states between 2014 and 2016. A multi-stage, stratified, random cluster sampling technique based on probability proportionate to size at each stage was used. The diagnosis of BPAD was based on Mini-International Neuropsychiatric Interview 6.0.0. Sheehan's Disability Scale was used to assess the disability. Results A total of 34,802 adults were interviewed. The overall weighted prevalence of BPAD was 0.3% [95% confidence interval (CI): 0.29-0.31] for current and 0.5% (95% CI: 0.49-0.51) for lifetime diagnosis. Male gender [odds ratio (OR) 1.56] and residence in urban metropolitans (OR 2.43) had a significantly higher risk of a lifetime diagnosis of BPAD. Substantial cross-sectional co-morbidities were noted as per MINI 6.0.0 with the diagnosis of current BPAD such as tobacco use disorder (33.3%), other substance use disorders (14.6%), and anxiety disorders (10.4%). Two-thirds of persons with current BPAD reported disability of varying severity at work (63%), social (59.3%), and family life (63%). The treatment gap for current BPAD was 70.4%. Conclusion Most individuals with current BPAD reported moderate-severe disability. There were substantial co-morbidities and a large treatment gap. These warrant concentrated efforts from policymakers in devising effective strategies.

Abstract
A remarkable feature of the brain is its sexual dimorphism. Sexual dimorphism in brain structure and function is associated with clinical implications documented previously in healthy individuals but also in those who suffer from various brain disorders. Sex-based differences concerning some features such as the risk, prevalence, age of onset, and symptomatology have been confirmed in a range of neurological and neuropsychiatric diseases. The mechanisms responsible for the establishment of sex-based differences between men and women are not fully understood. The present paper provides up-to-date data on sex-related dissimilarities observed in brain disorders and highlights the most relevant features that differ between males and females. The topic is very important as the recognition of disparities between the sexes might allow for the identification of therapeutic targets and pharmacological approaches for intractable neurological and neuropsychiatric disorders.

Abstract
Abstract
Background
Physical activity has been proposed to be beneficial for the symptomatic control of bipolar disorder, but the duration of the effects, sex-specific mechanisms, and impact of exercise intensity are not known.
Method
With an observational study design, we followed skiers and age and sex-matched non-skiers from the general population to investigate if participation in a long-distance cross-country ski race (Vasaloppet) was associated with a lower risk of getting diagnosed with bipolar disorder. Using the Swedish population and patient registries, skiers in Vasaloppet and age and sex-matched non-skiers from the general population were analyzed for any diagnosis of bipolar disorder after participation in the race. Additionally, we used finishing time of the ski race as a proxy for intensity levels to investigate if exercise intensity impacts the risk of bipolar disorder among the physically active skiers.
Results
Previous participation in a long distance ski race (n = 197,685, median age 36 years, 38% women) was associated with a lower incidence of newly diagnosed bipolar compared to an age and sex-matched general population (n = 197,684) during the up to 21 years follow-up (adjusted hazard ratio, HR = 0.48). The finishing time of the race did not significantly impact the risk of bipolar disorder in men. Among women, high performance (measured as the finishing time to complete the race, a proxy for higher exercise dose) was associated with an increased risk of bipolar disorder compared to slower skiing women (HR = 2.07).
Conclusions
Our results confirm that a physically active lifestyle is associated with a lower risk of developing bipolar disorder. Yet, to elucidate the direction of causality in this relationship requires complementary study designs. And the influence of physical performance level on the risk of bipolar disorder warrants further examinations among women.

Abstract
Prevalence of mental disorders, including major depressive disorder (MDD), bipolar disorder (BD) and schizophrenia (SZ) are increasing at alarming rates in our societies. Growing evidence points toward major sex differences in these conditions, and high rates of treatment resistance support the need to consider novel biological mechanisms outside of neuronal function to gain mechanistic insights that could lead to innovative therapies. Blood-brain barrier alterations have been reported in MDD, BD and SZ. Here, we provide an overview of sex-specific immune, endocrine, vascular and transcriptional-mediated changes that could affect neurovascular integrity and possibly contribute to the pathogenesis of mental disorders. We also identify pitfalls in current literature and highlight promising vascular biomarkers. Better understanding of how these adaptations can contribute to mental health status is essential not only in the context of MDD, BD and SZ but also cardiovascular diseases and stroke which are associated with higher prevalence of these conditions.

Abstract
OBJECTIVE The Bipolar Depression Rating Scale (BDRS) is a structured rating scale designed to assess depressive and mixed symptoms in bipolar disorder (BD). Previous studies evaluating the scale have been performed on small samples or on patients in a depressive phase, but not on patients in a mixed or manic phase. This study evaluated the Persian version of the BDRS regarding its factor structure, reliability, and validity in a large sample of Iranian women with BD in a depressive or mixed/manic phase. METHODS Three-hundred and one female BD inpatients completed the BDRS, the Beck Depression Inventory-II (BDI-II), the Hamilton Depression Rating Scale (HDRS), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Young Mania Rating Scale (YMRS). RESULTS The BDRS demonstrated a three-factor structure with good reliability. The BDRS and its psychological and somatic symptom clusters had stronger correlations with other measures of depressive symptoms than a measure of mania. The BDRS mixed symptom cluster also had a stronger correlation with a measure of mania than other measures of depression, supporting the scales' convergent and discriminant validity. CONCLUSIONS The BDRS demonstrated psychometric validity in assessing depressive and mixed symptoms in Iranian women with BD in a depressive or mixed/manic phase.KEY POINTSThe Bipolar Depression Rating Scale (BDRS) was validated in Iranian women with BD.The BDRS showed a three-factor structure, similar to the original validation.The BDRS had good reliability based on Omega and test-retest coefficients.The findings provided evidence for the convergent and discriminant validity of the BDRS.

Bipolar Disord 2022; 24:185-194. [PMID: 34263997 DOI: 10.1111/bdi.13116] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 05/20/2021] [Accepted: 07/02/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE Brain-derived neurotrophic factor (BDNF) rs6265 single-nucleotide polymorphism has been associated with bipolar disorder (BD), and with brain structure among adults with BD. We set out to investigate the association of the BDNF rs6265 Met allele with neurostructural phenotypes in youth BD. METHODS Caucasian youth (N = 99; 13-20 years; n = 56 BD, n = 43 age and sex-matched healthy controls) underwent 3-Tesla Magnetic Resonance Imaging and genotyping for BDNF rs6265. Region of interest (ROI) analyses of the ventromedial prefrontal cortex (vmPFC), anterior cingulate cortex (ACC), and hippocampus were complemented by vertex-wise analyses examining cortical thickness, surface area (SA) and volume. Multivariable models included the main effects of diagnosis and gene, and a diagnosis-by-genotype interaction term, controlling for age, sex, and intracranial volume. RESULTS There were no significant gene main effects or diagnosis-by-gene interaction effects in ROI analyses. The vertex-wise analysis yielded a significant gene main effect whereby Met allele carriers had greater middle temporal gyrus SA (p = 0.001) and supramarginal gyrus volume (p = 0.03) than Val/Val individuals. Significant interaction effects were found on lateral occipital lobe SA (p = 0.03), whereby the Met allele was associated with increased SA in BD only. Interaction effects were also found on postcentral gyrus SA (p = 0.049) and supramarginal gyrus SA (p = 0.04), with smaller SA in BD Met carriers versus healthy control Met carriers. CONCLUSION These findings suggest that BDNF rs6265 is differentially associated with regional SA in youth BD. Further investigation is warranted to evaluate whether BDNF protein levels mediate the observed effects, and to evaluate rs6265-related developmental changes.

Abstract
OBJECTIVE To examine gender disparities in the diagnosis of bipolar disorder (BD) within a privately insured population in the United States and investigate potential contributing factors for these gender differences. METHODS This retrospective cohort study utilized 2005-2017 claims data from the MarketScan® Commercial Claims and Encounters database. The study cohort included subjects, aged 10-64 years, who had a minimum of 1-year continuous insurance coverage and no record of a BD diagnosis before cohort entry. We examined the gender difference in BD diagnosis rate, overall and by subgroups. We then used Cox regression models to evaluate the gender effect on time to first BD diagnosis, and the potential moderators of gender effect. RESULTS The study cohort consisted of 97,193,443 subjects; 0.45% of subjects were diagnosed with BDs after cohort entry with males having a lower diagnosis rate than females (0.36% vs. 0.54%). The Cox regression analysis indicated that males were less likely to be diagnosed with BDs (unadjusted Hazard Ratio, HR [95% CI]: 0.69 [0.68-0.69]) and gender difference remained significant after adjusting for demographics, comorbidity and healthcare utilizations (adjusted HR [95% CI]: 0.77 [0.76-0.77]). Gender disparity was consistently strong among most age groups, but varied in other demographic subgroups. CONCLUSIONS Even though the prevalence of BDs is approximately equal between genders in the general population, our study found a much lower diagnosis rate in men compared to women for a privately insured U.S. POPULATION Future studies aimed at identifying and understanding the barriers to diagnosis of BDs in men are warranted.

Abstract
BACKGROUND While males are more likely diagnosed with cannabis use disorder (CUD), females are more susceptible to developing and maintaining CUD. Yet, for both sexes, CUD is associated with high rates of comorbid mental illness (MI). OBJECTIVES To identify and compare sex differences in the prevalence of comorbid CUD amongst individuals with/without MIs. METHODS This systematic review generated pooled odds ratios (OR) and 95% confidence intervals (CI) from 37 studies (including clinical trials, cohort, and case-control studies) among individuals with and without MIs, quantifying sex differences in rates of comorbid CUD. A meta-analysis was also completed. RESULTS In the CUD-only group, males were twice as likely to have CUD than females (OR = 2.0, CI = 1.9-2.1). Among MIs, males were more likely than females to have CUD comorbid with schizophrenia (OR ~2.6, CI = 2.5-2.7) and other psychotic, mood, and substance use disorders (1> OR <2.2, CI = 0.7-2.6). The reverse association (females > males) was observed for anxiety disorders and antisocial personality disorder (OR = 0.8, CI = 0.7-1.0). Among females, MIs increased the likelihood of having CUD, except for psychotic disorders and depression. A meta-analysis was inconclusive due to high heterogeneity across studies. Thus, comparisons across MI groups were not possible. CONCLUSION While males are more likely to be diagnosed with CUD, there are important sex differences in the prevalence of CUD across MI diagnoses that should be taken into account when approaching CUD prevention and determining treatment efficacy.

Abstract
The objectives of this study were to determine whether gender differences exist in how social support, and different types of support, impact psychological distress among Canadian adults with bipolar I and bipolar II disorder (BD), to examine whether females and males with BD differ in their perceived levels of support and distress compared to females and males without BD, and to investigate whether females and males with BD perceive different levels of support and distress. Using a cross-sectional, national datafile, 281 females and 282 males (20-64 years) who reported being diagnosed with BD were investigated using the Social Provisions Scale (SPS) and the Kessler Psychological Distress Scale (K10). It was found that females and males with BD had significantly lower SPS scores and significantly higher K10 scores than females and males without BD, females with BD perceive significantly higher overall support, as well as higher attachment and guidance compared to males with BD, and support in the form of social integration and was associated with decreased psychological distress for both males and females with BD. Furthermore, reassurance of worth was an additional predictor of decreased distress for males, while guidance was an additional predictor of decreased distress for females. Despite the limitations, which include self-reported diagnosis of BD and potential exclusion of those who are not diagnosed but have BD, these findings suggest that different types of social support may serve as protective factors for psychological distress among females and males with BD.

Abstract
The clinical features and course of bipolar disorder differ between women and men; however, studies are limited in Indian population. The objective of this study was to identify gender differences in patients with bipolar disorder. This was a cross-sectional, hospital-based observational study conducted over a period of 25 months. The sample consisted of 110 males and 90 females with a diagnosis of bipolar disorder according to ICD-10 Diagnostic Criteria for Research. Socio-demographic and clinical details were collected using semi-structured proforma. All patients were evaluated on Mini International Neuropsychiatric Interview Plus, Presumptive Stressful Life Events Scale and Clinical Global Impression. Sample consisted of 55% men and 45% women. The total number of episodes was similar between genders, however, the number of manic episodes (p = 0.004) was significantly more in males and the number of depressive (p = 0.003) and mixed episodes (p = 0.018) were significantly more in females. Majority of males had first episode of mania, whereas, first episode in females were mostly depressive (p < 0.001). Comorbid physical disorders were seen in 61.1% females and 40% males. Bipolar disorder subtype, episode types and number varied across gender. Co-morbid hypothyroidism, migraine, and obesity are seen more often in women and substance use was higher in men.

Abstract
While research has identified alterations in dorsolateral prefrontal cortical function as a key factor to the etiology of bipolar disorder, few studies have uncovered robust changes in protein signal transduction pathways in this disorder. Given the direct relevance of protein-based expressional alterations to cellular functions and because many of the key regulatory mechanisms for the disease pathogenesis likely include alterations in protein activity rather than changes in expression alone, the identification of alterations in discrete signal transduction pathways in bipolar disorder would have broad implications for understanding the disease pathophysiology. As prior microarray data point to a previously unrecognized involvement of the RhoA network in bipolar disorder, here we investigate the protein expression and activity of key components of a RhoA signal transduction pathway in dorsolateral prefrontal cortical homogenates from subjects with bipolar disorder. The results of this investigation implicate overactivation of prefrontal cortical RhoA signaling in specific subtypes of bipolar disorder. The specificity of these findings is demonstrated by a lack of comparable changes in schizophrenia; however, our findings do identify convergence between both disorders at the level of activity-mediated actin cytoskeletal regulation. These findings have implications for understanding the altered cortical synaptic connectivity of bipolar disorder.

Abstract
BACKGROUND The clinical and epidemiological features of bipolar disorder (BD) between females and males have many differences. The association between brain function and gender in BD is unknown. This research aimed to investigate the association between brain function and gender in BD by using amplitude of low-frequency fluctuations (ALFFs). METHODS Ninety-eight patients (49 females and 49 males) with BD and 171 matched healthy controls (HCs, 89 females and 82 males) were recruited for resting-state functional magnetic resonance imaging. ALFF was used to estimate brain function. RESULTS A main effect of diagnosis in ALFF was observed in the dorsal lateral prefrontal cortex (DLPFC), ventral prefrontal cortex (VPFC), caudate and occipital lobe. A main effect of gender in ALFF was found in the right VPFC, DLPFC, thalamus, and occipital lobe. A main effect of diagnosis gender interaction in ALFF was observed in the left DLPFC. Analyses of two-sample t-test indicated that male patients with BD had increased ALFF in the right hippocampus, right amygdala, left caudate, and left DLPFC, and decreased ALFF in the occipital lobe compared with male HC. Female patients with BD demonstrated increased ALFF in the right VPFC and right DLPFC compared with female HC. Male patients with BD exhibited increased ALFF in the right VPFC and left DLPFC and decreased ALFF in the occipital lobe compared with female patients with BD. LIMITATIONS This study did not consider the effect of medications and emotional states on brain activity. CONCLUSIONS Results suggested gender differences in the dysfunctions of the cortico-limbic neural system in BD.

Abstract
OBJECTIVES This multicentric study from India aimed to evaluate the long term course and outcome of bipolar disorder (BD). METHOD Seven hundred and seventy-three participants diagnosed with BD, attending 14 outpatient clinic centers across the country, were evaluated using the National Institute of Mental Health- Retrospective Life Charts to assess the long term course of BD. RESULTS The mean age of onset of the first episode of illness of the study sample was 26.3 (8.54) years, and mean duration of illness at the time of assessment was 233.05 (94.55) months. In terms of the total number of lifetime episodes, the mean number of manic episodes (mean: 3.68; SD: 4.75) exceeded the mean number of depressive episodes (mean: 3.36; SD: 5.51). The mean numbers of total lifetime episodes were 8.58 (10.6%). When the number of episodes per year was computed, the mean number of manic episodes per year exceeded that of the mean number of depressive episodes. Compared to females, a higher proportion of males had a history of comorbid substance dependence. LIMITATIONS The course was assessed retrospectively and the study was limited to participants attending the outpatient clinics. CONCLUSIONS The course of BD in India differs from that described from developed countries in the form of a number of manic episodes exceeding the depressive episodes.

Abstract
Bipolar disorder (BD) differs in its clinical presentation in females compared to males. A number of clinical characteristics have been associated with BD in females: more rapid cycling and mixed features; higher number of depressive episodes; and a higher prevalence of BD type II. There is a strong link between BD and risk for postpartum mood episodes, and a substantial percentage of females with BD experience premenstrual mood worsening of varying degrees of severity. Females with premenstrual dysphoric disorder (PMDD)-the most severe form of premenstrual disturbances-comorbid with BD appear to have a more complex course of illness, including increased psychiatric comorbidities, earlier onset of BD, and greater number of mood episodes. Importantly, there may be a link between puberty and the onset of BD in females with comorbid PMDD and BD, marked by a shortened gap between the onset of BD and menarche. In terms of neurobiology, comorbid BD and PMDD may have unique structural and functional neural correlates. Treatment of BD comorbid with PMDD poses challenges, as the first line treatment of PMDD in the general population is selective serotonin reuptake inhibitors, which produce risk of treatment-emergent manic symptoms. Here, we review current literature concerning the clinical presentation, illness burden, and unique neurobiology of BD comorbid with PMDD. We additionally discuss obstacles faced in symptom tracking, and management of these comorbid disorders.

Abstract
OBJECTIVES Studies suggest that men and women have different vulnerabilities to a number of substance use disorders (SUDs). We examined whether differences between women and men with opioid use disorder (OUD) are significantly different from those without OUD for selected sociodemographic and health outcomes. METHODS We used a cross-sectional survey design using data from 2012 to 2013 National Epidemiological Survey on Alcohol and Related Conditions Wave III, which surveyed nationally representative samples of non-institutionalized adults (n = 36,309 unweighted). Past-year OUD and other behavioral co-morbidities were defined using DSM-5 criteria. In bivariate analyses, we investigated sex differences in socio-demographic factors, behavioral co-morbidities, pain, and health-related quality of life (HRQOL) between women and men with past-year OUD, and then those without past-year OUD. We further used logistic regression analyses to evaluate interactions between effect of sex and past-year OUD status on behavioral co-morbidities, pain, and HRQOL. RESULTS When extrapolated, about 2.1 million US adults met diagnostic criteria for past-year OUD. Women with OUD had a higher likelihood of having several past-year psychiatric disorders, and a lower likelihood of having any past-year SUDs compared to male counterparts. However, similar relationships were observed among those without OUD and significant interaction effects were not found on behavioral co-morbidities, pain, and HRQOL, indicating that general sex differences are not specific to OUD. CONCLUSIONS Although sex differences are not specific to OUD, concurrent disorders are not uncommon among women, as well as men, with OUD. There is a need to treat concurrent behavioral health conditions from a multimorbidity perspective in the treatment of OUD in both sexes.

Abstract
BACKGROUND Despite evidence of gender differences in bipolar disorder characteristics and comorbidity, there is little research on the differences in treatment and service use between men and women with bipolar disorder. AIMS To use routine data to describe specialist mental health service contact for bipolar disorder, including in-patient, community and support service contacts; to compare clinical characteristics and mental health service use between men and women in contact with secondary services for bipolar disorder. METHOD Cross-sectional analysis of mental health patients with bipolar disorder in New Zealand, based on complete national routine health data. RESULTS A total of 3639 individuals were in contact with specialist mental health services with a current diagnosis of bipolar disorder in 2015. Of these 58% were women and 46% were aged 45 and over. The 1-year prevalence rate of bipolar disorder leading to contact with specialist mental health services was 1.56 (95% CI 1.50-1.63) per 100 000 women and 1.20 (95% CI 1.14-1.26) per 100 000 men. Rates of bipolar disorder leading to service contact were 30% higher in women than men (rate ratio 1.30, 95% CI 1.22-1.39). The majority (68%) had a diagnosis of bipolar I disorder. Women were more likely to receive only out-patient treatment and have comorbid anxiety whereas more men had substance use disorder, were convicted for crimes when unwell, received compulsory treatment orders and received in-patient treatment. CONCLUSIONS Although the prevalence of bipolar disorder is equal between men and women in the population, women were more likely to have contact with specialist services for bipolar disorder but had a lower intensity of service interaction.

Effects of job stress on symptoms of bipolar spectrum disorder in an electronic parts manufacturing company. Ann Occup Environ Med 2020; 32:e25.

Abstract
Background Mental illness is known to be caused by genetic, biological, and environmental risk factors. Although previous studies have established the link between mental illness and job stress, most of them are limited to major depression disorder. Therefore, this study examined the relationship between job stress and bipolar spectrum disorder (BSD). Methods This is a cross-sectional study based on a survey conducted in April 2017 at an electronic parts manufacturing company in Busan. In a total of 441 workers, the degree of BSD was identified using the Korean version of the Mood Disorder Questionnaire, and the degree of job stress was identified using the Korean Occupational Stress Scale Short Form. This study also identified general characteristics of workers and job-related factors. The χ2 test and Fisher's exact test was conducted to determine the differences among the variables, based on BSD. Multiple logistic regression analysis was conducted to determine the influence of independent variables on BSD. Results Cross-analysis showed significant differences between the BSD high-risk and low-risk groups regarding age, sex, occupation, smoking, problem drinking, job stress total score, occupational climate, and major depression disorder symptom. In addition, the significant differences between the BSD high-risk and low-risk groups about job stress were observed in terms of job demand, job insecurity, and occupational climate. A multiple logistic regression analysis revealed that the high-risk group in the job stress group had a higher effect on BSD than the low-risk group (odds ratio [OR]: 2.32, 95% confidence interval [CI]: 1.10–4.88). Among the categories of job stress, high-risk groups in 3 areas—job demand (OR: 2.56, 95% CI: 1.27–5.17), job insecurity (OR: 4.42, 95% CI: 1.19–16.42), and occupational climate (OR: 2.55, 95% CI: 1.29–5.05)—were more likely to have an impact on BSD than the low-risk groups. Conclusions This study demonstrated that the high-risk groups of job stress total score, job demand, job insecurity, and occupational climate had a more significant effect on BSD than the low-risk groups. As workers with BSD may have difficulties in their work and personal lives, there is a need to manage job stress to prevention of BSD.

Abstract
BACKGROUND Oral antipsychotic (AP) medications are frequently prescribed to people with bipolar I disorder (BD-I). A cross-sectional online survey examined the experiences of people living with BD-I with a history of recent AP use. METHODS Adults with self-reported physician-diagnosed BD-I (N = 200) who received oral APs during the prior year completed a survey on AP-related experiences, including side effects and their perceived burden on social functioning, adherence, and work. Items also assessed preferences for trade-offs (balancing symptom management and side effects) when considering a hypothetical new AP. The perceived impact of specific, prevalent side effects on adherence, work, and preferences for a hypothetical AP were also examined. Analyses were descriptive. RESULTS The survey sample had a mean age of 43.2 (SD = 12.4) years, was 60% female, and 31% nonwhite. Almost all participants (98%) had experienced AP side effects. Common self-reported side effects were feeling drowsy or tired (83%), lack of emotion (79%), anxiety (79%), dry mouth (76%), and weight gain (76%). Weight gain was cited as the most bothersome side effect, rated by most participants (68%) as "very" or "extremely bothersome." Nearly half of participants (49%) reported that AP side effects negatively impacted their job performance; almost all (92%) reported that side effects - most commonly anxiety and lack of emotion - negatively impacted social relationships (e.g., family or romantic partners). The most commonly-reported reason for stopping AP use was dislike of side effects (48%). Side effects most likely to lead to stopping or taking less of AP treatment included "feeling like a 'zombie'" (29%), feeling drowsy or tired (25%), and weight gain (24%). When considering a hypothetical new AP, the most common side effects participants wanted to avoid included AP-induced anxiety (50%), weight gain (48%), and "feeling like a 'zombie'" (47%). CONCLUSIONS Side effects of APs were both common and bothersome, and impacted social functioning, adherence, and work. Findings highlight the prevailing unmet need for new APs with more favorable benefit-risk profiles.

Abstract
Many neuropsychiatric disorders exhibit differences in prevalence, age of onset, symptoms or course of illness between males and females. For the most part, the origins of these differences are not well understood. In this article, we provide an overview of sex differences in psychiatric disorders including autism spectrum disorder (ASD), attention deficit/hyperactivity disorder (ADHD), anxiety, depression, alcohol and substance abuse, schizophrenia, eating disorders and risk of suicide. We discuss both genetic and nongenetic mechanisms that have been hypothesized to underlie these differences, including ascertainment bias, environmental stressors, X‐ or Y‐linked risk loci, and differential liability thresholds in males and females. We then review the use of twin, family and genome‐wide association approaches to study potential genetic mechanisms of sex differences and the extent to which these designs have been employed in studies of psychiatric disorders. We describe the utility of genetic epidemiologic study designs, including classical twin and family studies, large‐scale studies of population registries, derived recurrence risks, and molecular genetic analyses of genome‐wide variation that may enhance our understanding sex differences in neuropsychiatric disorders.

Abstract
AbstractAims:To assess the comorbidity rates of alcohol use disorders (AUDs) in bipolar disorder (BD) and to explore possible sources of heterogeneity.Methods:Studies were identified through database searches. Meta-analytic techniques were employed to aggregate data on lifetime comorbidity and to explore possible sources of heterogeneity. Funnel plots were used to detect publication bias.Results:In clinical studies, AUDs affected more than one in three subjects with BD. Significant heterogeneity was found, which was largely explained by the geographical location of study populations and gender ratio of participants. AUDs affected more than one in five women and two in five men.Conclusion:AUDs are highly prevalent in BD. Our study revealed a substantial heterogeneity across studies. Further research including control groups is needed. Patients with BD should be assessed for current and previous AUDs.

Critical Predictors for the Early Detection of Conversion From Unipolar Major Depressive Disorder to Bipolar Disorder: Nationwide Population-Based Retrospective Cohort Study. JMIR Med Inform 2020; 8:e14278.

Abstract
BACKGROUND Unipolar major depressive disorder (MDD) and bipolar disorder are two major mood disorders. The two disorders have different treatment strategies and prognoses. However, bipolar disorder may begin with depression and could be diagnosed as MDD in the initial stage, which may later contribute to treatment failure. Previous studies indicated that a high proportion of patients diagnosed with MDD will develop bipolar disorder over time. This kind of hidden bipolar disorder may contribute to the treatment resistance observed in patients with MDD. OBJECTIVE In this population-based study, our aim was to investigate the rate and risk factors of a diagnostic change from unipolar MDD to bipolar disorder during a 10-year follow-up. Furthermore, a risk stratification model was developed for MDD-to-bipolar disorder conversion. METHODS We conducted a retrospective cohort study involving patients who were newly diagnosed with MDD between January 1, 2000, and December 31, 2004, by using the Taiwan National Health Insurance Research Database. All patients with depression were observed until (1) diagnosis of bipolar disorder by a psychiatrist, (2) death, or (3) December 31, 2013. All patients with depression were divided into the following two groups, according to whether bipolar disorder was diagnosed during the follow-up period: converted group and nonconverted group. Six groups of variables within the first 6 months of enrollment, including personal characteristics, physical comorbidities, psychiatric comorbidities, health care usage behaviors, disorder severity, and psychotropic use, were extracted and were included in a classification and regression tree (CART) analysis to generate a risk stratification model for MDD-to-bipolar disorder conversion. RESULTS Our study enrolled 2820 patients with MDD. During the follow-up period, 536 patients were diagnosed with bipolar disorder (conversion rate=19.0%). The CART method identified five variables (kinds of antipsychotics used within the first 6 months of enrollment, kinds of antidepressants used within the first 6 months of enrollment, total psychiatric outpatient visits, kinds of benzodiazepines used within one visit, and use of mood stabilizers) as significant predictors of the risk of bipolar disorder conversion. This risk CART was able to stratify patients into high-, medium-, and low-risk groups with regard to bipolar disorder conversion. In the high-risk group, 61.5%-100% of patients with depression eventually developed bipolar disorder. On the other hand, in the low-risk group, only 6.4%-14.3% of patients with depression developed bipolar disorder. CONCLUSIONS The CART method identified five variables as significant predictors of bipolar disorder conversion. In a simple two- to four-step process, these variables permit the identification of patients with low, intermediate, or high risk of bipolar disorder conversion. The developed model can be applied to routine clinical practice for the early diagnosis of bipolar disorder.

Abstract
OBJECTIVES Acute mania is a serious medical condition that impacts men and women equally. Longtime presentation of manic symptoms is sex-dependent; however, little is known about acute symptoms of mania. The objective of this study is to track and compare acute manic symptoms for sex differences during inpatient hospitalization. METHODS All patients with bipolar mania admitted to a large university hospital between January and October 2017 were invited to participate in this longitudinal naturalistic follow-up study. Manic (YMRS), depressive (MADRS), and psychotic (PAS) symptoms were tracked daily from admission to discharge. RESULTS The total YMRS scores decreased significantly overtime (p < .0001) in both male (n = 34) and female (n = 23) patients (p = .7). However, male patients scored significantly higher in sexual interest (p = .01), disruptive and aggressive behavior (p = .01), and appearance (p < .001) while females had better insight into their illness (p = .01). Males and females received similar doses of lithium (p = .1), but males received significantly higher doses of valproic acid (VPA) in comparison with females (p = .003). However, plasma lithium and VPA concentrations at discharge were not significantly different between sexes. CONCLUSION Our results show sex differences in the progression of certain domains of manic symptoms in a cohort of 23 female and 34 male patients admitted to a large academic center in Turkey. Males, in this sample, exhibited more sexual interest, disruptive and aggressive behaviors, better grooming, and less insight compared to females. While these results are concordant with our preclinical findings and with anecdotal clinical observations, replication in larger samples is needed.

Abstract
OBJECTIVE The possible presence of gender-related differences in patients with bipolar disorder (BD) may have diagnostic and therapeutic implications. This multicenter study aimed to investigate gender differences in BD in the largest Italian database collected to date, on behalf of the Italian Chapter of the International Society of Bipolar Disorders. METHODS A total of 1674 patients (males: n = 714; females: n = 960) from different psychiatric departments were compared according to gender on demographic/clinical variables. Owing to the large number of variables statistically related to the dependent variable (gender) at the univariate analyses, preliminary multiple logistic regression analyses were performed. A final multivariable logistic regression was then performed, considering gender as the dependent variable and statistically significant demographic/clinical characteristics as independent variables. RESULTS The results of the final multivariable logistic regression analysis with previous statistically significant demographic and clinical variables were the following: female gender was less frequently associated with employment (odds ratio [OR] = 0.7, P < 0.01), lifetime single marital status (OR = 0.45, P < 0.01), and substance abuse in the last year (OR = 0.35, P < 0.01), whereas it was more frequently associated with a major number of lifetime major depressive episodes (OR = 1.78, P < 0.01) and psychiatric visits in the last year (OR = 1.38, P = 0.01). CONCLUSION Few significant differences were found between genders in BD, particularly for those clinical features that are associated with poor prognosis (substance abuse for males and number of depressive episodes for females). Transcultural studies are needed to identify cultural versus illness-related variables possibly explaining the different clinical presentation of BD in relation to gender.

The comorbidity of eating disorders in bipolar disorder and associated clinical correlates characterised by emotion dysregulation and impulsivity: A systematic review.

Abstract
BACKGROUND Individuals with bipolar disorder (BD) have an increased risk of developing eating disorders (ED) or disordered eating symptoms compared to the general population. Eating pathology characterised by binge and/or purge symptomatology are the most common to develop in BD, yet the underlying aetiological mechanisms are relatively unknown. Theoretical models of BD-ED comorbidity suggest that shared pathophysiological factors, including emotion dysregulation and impulsivity may contribute to the development of binge/purge eating pathology in BD. METHOD A systematic search was conducted to assess two research questions: 1. What are the prevalence or incidence rates of different ED in BD? 2. Are clinical correlates hallmarked by emotion dysregulation and/or impulsivity (alcohol/substance use disorders, mood instability and suicidality) significantly elevated in BD with ED (BD-ED) groups compared to BD only? RESULTS Any type of lifetime or current ED ranged from 1.9% to 33.3% in BD. Type of BD diagnosis did not appear to significantly impact likelihood of ED development. Alcohol use disorder, mood instability and suicidality were significantly higher in BD-ED compared to BD only. LIMITATIONS Potential biases within the selected studies; impacting generalisability of results and comparability between studies. Varying treatment interventions (including medications) may confound results and comparability between studies. Assessment of binge eating varied, also limiting comparability. CONCLUSION Eating pathology may occur comorbidly with BD due to shared underlying pathophysiological features. This could have significant implications for future interventions; both psychopharmacological and psychotherapeutic. More comprehensive investigations are required to identify the functionality of dysregulated emotion and impulsivity in the development of eating pathology in BD.

Abstract
In this review, we describe the sex differences in prevalence, onset, symptom profiles, and disease outcome that are evident in schizophrenia, bipolar disorder, and post-traumatic stress disorder. Women with schizophrenia tend to exhibit less disease impairment than men. By contrast, women with post-traumatic stress disorder are more affected than men. The most likely candidates to explain these sex differences are gonadal hormones. This review details the clinical evidence that oestradiol and progesterone are dysregulated in these psychiatric disorders. Notably, existing data on oestradiol, and to a lesser extent, progesterone, suggest that low levels of these hormones may increase the risk of disease development and worsen symptom severity. We argue that future studies require a more inclusive, considered analysis of gonadal steroid hormones and the intricacies of the interactions between them, with methodological rigour applied, to enhance our understanding of the roles of steroid hormones in psychiatric disorders.

Cingulate abnormalities in bipolar disorder relate to gender and outcome: a region-based morphometry study [corrected]. Eur Arch Psychiatry Clin Neurosci 2019; 269:777-784. [PMID: 29594394 DOI: 10.1007/s00406-018-0887-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2017] [Accepted: 03/16/2018] [Indexed: 12/22/2022]
Abstract
Structural magnetic resonance imaging (MRI) studies reported gray matter (GM) loss in bipolar disorder (BD) in cingulate cortices, key regions subserving emotional regulation and cognitive functions in humans. The aim of this study was to further explore cingulate GM volumes in a sizeable group of BD patients with respect to healthy controls, particularly investigating the impact of gender and clinical variables. 39 BD patients (mean Age = 48.6 ± 9.7, 15 males and 24 females) and 39 demographically matched healthy subjects (mean Age = 47.9 ± 9.1, 15 males and 24 females) underwent a 1.5T MRI scan. GM volumes within the cingulate cortex were manually detected, including anterior and posterior regions. BD patients had decreased left anterior cingulate volumes compared with healthy controls (F = 6.7, p = 0.01). Additionally, a significant gender effect was observed, with male patients showing reduced left anterior cingulate cortex (ACC) volumes compared to healthy controls (F = 5.1, p = 0.03). Furthermore, a significant inverse correlation between right ACC volumes and number of hospitalizations were found in the whole group of BD patients (r = - 0.51, p = 0.04) and in male BD patients (r = - 0.88, p = 0.04). Finally, no statistically significant correlations were observed in female BD patients. Our findings further confirm the putative role of the ACC in the pathophysiology of BD. Interestingly, this study also suggested the presence of gender-specific GM volume reductions in ACC in BD, which may also be associated to poor outcome.

[PMID: 31177046 DOI: 10.1016/j.jad.2019.05.052] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Revised: 04/03/2019] [Accepted: 05/27/2019] [Indexed: 02/09/2023]
Abstract
BACKGROUND The influence of gender on bipolar disorder is controversial and it is unclear if inpatient care differs between men and women. Here, we investigate for gender differences in the inpatient length of stay for Swedes admitted for bipolar disorder and explore other factors that could explain any observed association. METHODS Admission data were extracted from the Swedish National Patient Register and included all patients first admitted to a psychiatric inpatient unit with a bipolar disorder diagnosis, circa 2005-2014. Patients were then retrospectively followed for subsequent hospitalizations. Diagnostic subtypes were categorized by ICD-10 clusters: depressive, depressive with psychotic features, manic, manic with psychotic features, mixed, and other. Psychotropic therapies preceding the corresponding admissions were attained from the Prescribed Drug Register. Mixed-effects zero-truncated negative binomial regressions were employed to model the length of stay per admission. RESULTS Analysis included 39,653 admissions by 16,271 inpatients (60.0% women). Overall, when compared to men, women spent 7.5% (95% CI: 4.2-11.0%, p < 0.001) extra days hospitalized per admission. However, upon adjusting for candidate confounders, including the bipolar subtype, and selected comorbidities and psychotropics, the association weakened wherein women then spent 3.7% (95% CI: 0.1-6.9%, p = 0.028) extra days hospitalized per admission. LIMITATIONS The integrity of register data can be variable and the adherence to outpatient dispensed psychotropics could not be validated. CONCLUSION Although the influence of gender on the bipolar disorder inpatient length of stay is evident, other factors attenuate and better explain this crude observation.

Abstract
BACKGROUND Partners of patients with bipolar affective disorder (BPAD) have problems with their marital life. Identification of these problems is important to develop strategies to solve them for improving quality of life. AIMS To identify marital distress and problem areas in their marital life among the partners of patients with BPAD. MATERIALS AND METHODS A cross-sectional descriptive design was used to collect data from 125 participants, 59 males and 66 females, who were partners of patients with BPAD. The study was done in outpatient clinics of Community Mental Health Clinics of District Mental Health Program. Tools used for data collection included a semi-structured interview schedule to collect socio-personal data of partners of patients with BPAD and clinical data of the patient, Couple Satisfaction Index (CSI), and Problem Areas Questionnaire (PAQ). Purposive sampling technique was used. RESULTS Majority of the participants (male - 55.9%, female -54.5%) expressed marital distress on CSI. Handling family finances and career/job decisions were the most problematic areas for male participants, whereas household tasks, handling finances, and career/job decisions were the most problematic areas for female participants. CONCLUSION A significant proportion of spouses of BPAD patients have marital distress in important areas of life, with a potential for long-term consequences in their lives.

Traits related to bipolar disorder are associated with an increased post-illumination pupil response. Psychiatry Res 2019; 278:35-41.

Abstract
Mood states in bipolar disorder appear to be closely linked to changes in sleep and circadian function. It has been suggested that hypersensitivity of the circadian system to light may be a trait vulnerability for bipolar disorder. Healthy persons with emotional-behavioural traits associated with bipolar disorder also appear to exhibit problems with circadian rhythms, which may be associated with individual differences in light sensitivity. This study investigated the melanopsin-driven post-illumination pupil response (PIPR) in relation to emotional-behavioural traits associated with bipolar disorder (measured with the General Behavior Inventory) in a non-clinical group (n = 61). An increased PIPR was associated with increased bipolar disorder-related traits. Specifically, the hypomania scale of the General Behavior Inventory was associated with an increased post-blue PIPR. Further, both the full hypomania and shortened '7 Up' scales were significantly predicted by PIPR, after age, sex and depressive traits were controlled. These findings suggest that increased sensitivity to light may be a risk factor for mood problems in the general population, and support the idea that hypersensitivity to light is a trait vulnerability for, rather than symptom of, bipolar disorder.

Abstract
Twin- and family studies have shown variations in the heritability estimates of bipolar disorder (BPD). The current study uses an updated statistical methodology for heritability estimation in BPD by taking available time of follow-up into account while controlling for co-variates. We identified monozygotic and dizygotic same and different sex twins with BPD (n = 804) or unaffected from BPD (n = 91,604) from the Swedish Twin Register and the National Patient Register. We applied structural equational modeling with inversed probability weighting to estimate the heritability, taking into account censoring and truncation of data. Sex-limitation models were constructed to analyze qualitative or quantitative sex-differences in BPD. Heritability for BPD was 60.4% (95% Confidence Interval: 50.3-70.5) after age, sex, left-hand truncation and censoring of the data was taken into account. A larger proportion of females were affected from BPD (females 62.2%; males 37.8%, p < 0.001), but no sex-difference in BPD heritability was found, nor any sex-specific genetic effects. We demonstrated a robust 60% heritability for BPD with no evidence of sex-specific genetic effects on disease liability.

Abstract
Some women affected by mood disorders experience mood instability during the premenstrual phase. Assuming that fluctuations in drug serum levels may contribute to the worsening of mood symptoms, we carried out a systematic review of available studies that investigated changes in lithium and valproate levels in relation to menstrual phases. We selected five studies; four of which assessed menstrual fluctuations in lithium serum levels and one in valproate levels. Study samples included women in their fertile age affected by bipolar disorder, epilepsy as well as healthy ones. Preliminary results showed a close relationship between cyclic premenstrual exacerbation of affective symptoms and a significant decrease in lithium levels during the luteal phase, despite stable oral doses, in bipolar women. In healthy women, lithium levels were influenced by neither menstrual cycle phases nor oral contraceptives use. Valproate serum levels in epileptic women showed a small, nonsignificant decline during the mid-luteal phase. Pharmacokinetic sex differences in adsorption, volume distribution, hepatic metabolism, and renal excretion of mood stabilizers have been supposed to partly explain such menstrual serum level fluctuations. A better understanding in this field could help to counteract the distress related to premenstrual phase, improving therapeutic management of mood disorders in women.

Abstract
This study aimed to estimate the gender differences, family size and fertility rate among patients with Bipolar disorder (BD). 219 patients diagnosed with BD, who were married for at least 3 years and aged more than 25 years were assessed clinically for the course of illness as per the NIMH-life chart. Fertility and infertility were assessed based on the information on number of living children, abortions and medical termination of pregnancies. Significantly higher proportion of male patients had comorbid substance dependence while females had significantly higher prevalence of physical comorbidity. Additionally, female participants reported significantly higher mean number of depressive episodes per year of illness and suicidal attempts. When marriage was considered as a life event and its association with onset or relapse of illness was evaluated, about one-fourth (23.3%) of the study sample reported relapse of illness at the time of marriage or immediately following the marriage. About one-fourth (24.7%) of the couple with one of the partner having bipolar disorder had no living children even after four years of their marriage. To conclude, this study suggests that there are certain gender differences with regard to the clinical profile and longitudinal course of illness of BD.

Abstract
Brain disorders and mental diseases, in particular, are common and considered as a top global health challenge for the twenty-first century. Interestingly, women suffer more frequently from mental disorders than men. Moreover, women may respond to psychotropic drugs differently than men, and, through their lifespan, they endure sex-orientated social stressors. In this chapter, we present how women may differ in the development and manifestation of mental health issues and how they differ from men in pharmacokinetics and pharmacodynamics. We discuss issues in clinical trials regarding women participation, issues in the use of psychotropic medications in pregnancy, and challenges that psychiatry faces as a result of the wider use of contraceptives, of childbearing at older age, and of menopause. Such issues, among others, demand further women-oriented psychiatric research that can improve the care for women during the course of their lives. Indeed, despite all these known sex differences, psychiatry for both men and women patients uses the same approach. Thereby, a modified paradigm for women's psychiatry, which takes into account all these differences, emerges as a necessity, and psychiatric research should take more vigorously into account sex differences.

Abstract
Clinical and epidemiological research suggests that behavioral addictions (BA) are associated with a wide range of psychiatric disorders. However, the relationship between BA and bipolar disorders (BD) has not been thoroughly explored. The aim of this systematic review was to critically summarize and evaluate the current available evidence regarding a possible association between BA and BD. A systematic review of major electronic databases according to PRISMA guidelines was conducted from inception to 31st December 2017. We sought quantitative studies data concerning prevalence of comorbidity, features and treatment related to BA-BD comorbidity. Data were narratively synthesized. Of the 1250 studies returned from the search, a total of 28 articles were included in this review. BA may be overrepresented in BD samples, and the other way around. Pathological gambling and kleptomania were the most prevalent conditions followed by compulsive buying, compulsive sexual behavior and internet addiction. BA was also associated with other mood disorders, anxiety disorders and substance use disorder. BD-BA comorbidity was related with more severe course of illness. Studies on treatment strategies for BD-BA comorbidity are rather limited; only one randomized controlled trial that fulfilled inclusion criteria was identified. Methodological heterogeneity in terms of design and results among studies was found. BD-BA commonly co-occurs although there is a need for rigorous studies. Routine screening and adequate assessment may be helpful in BD patients to identify individuals at risk for BA and to effectively manage the complex consequences associated with BA-BD comorbidity.

Abstract
Men and women often experience different symptoms or rates of occurrence for a variety of mood disorders. Many of the symptoms of mood disorders overlap with autoimmune disorders, which also have a higher prevalence in women. There is a growing interest in exploring the immune system to provide biomarkers for diagnosis of mood disorders, along with new targets for developing treatments. This review examines known sex differences in the immune system and their relationship to mood disorders. We focus on immune alterations associated with unipolar depression, bipolar depression, and anxiety disorders. We describe work from both basic and clinical research examining potential immune mechanisms thought to contribute to stress susceptibility and associated mood disorders. We propose that sex and age are important, intertwined factors that need to be included in future experimental designs if we are going to harness the power of the immune system to develop a new wave of treatments for mood disorders.

Abstract
BACKGROUND In the last decades, there has been increasing interest in investigating the role of the vermis in bipolar disorder (BD), especially because of its involvement in cognitive processes. The main aims of this study were to explore the integrity of the vermis and elucidate the role of demographic and clinical variables on vermis volumes in BD patients, stratified according to gender. METHODS T1-weighted images were obtained for 38 BD patients and 38 healthy controls using a 1.5-T MRI scanner. Images were analyzed with a PC workstation with BRAINS2 software on a Linux system. Anatomical regions were traced manually from a blinded operator, with respect to subject identity and other clinical variables. RESULTS The direct comparison between the 2 groups showed no significant gray matter differences in vermis volumes. Interestingly, vermis volumes were significantly inversely associated with chronological age and age of BD onset, particularly in male subjects. CONCLUSIONS Our study provides evidence of the impact of aging on the vermis in BD, potentially related to earlier and faster gender-related neurodegenerative phenomena occurring during the progression of the disease.

Abstract
OBJECTIVE The aim of our study is to determine the difference between the bipolar disorder, unipolar disorder and control groups in terms of maladaptive schemes and childhood trauma. METHODS Two groups of patients under monitoring with a diagnosis of bipolar or unipolar disorder and one group of healthy controls were enrolled in this study. Each group consisted of 60 subjects. The Young Mania Rating Scale and Beck Depression Inventory were used to confirm that patients were in remission. The Childhood Trauma Questionnaire and Young Schema Questionnaire-Short Form 3 were used to identify childhood traumas and early maladaptive schemas. RESULTS In bipolar disorder, a positive, low power correlation was observed between the vulnerability to threats schema and emotional, physical and sexual abuse. In the unipolar disorder group, there was a positive, low power correlation between the emotional inhibition, failure, approval seeking, dependence, abandonment and defectiveness schemas and social isolation, and a positive, moderate correlation between social isolation and emotional abuse. CONCLUSIONS Individuals with bipolar disorder suffered greater childhood trauma compared to subjects with unipolar disorder and healthy individuals. Greater maladaptive schema activation were present in individuals with bipolar disorder compared to those with unipolar disorder and healthy individuals.

Psychiatry Res 2018; 261:517-521. [PMID: 29395874 DOI: 10.1016/j.psychres.2017.12.061] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Revised: 12/16/2017] [Accepted: 12/30/2017] [Indexed: 11/26/2022]
Abstract
Mental disorders may confer a high risk of traumatic brain injury, but only rare studies have investigated mood disorders. This nationwide cohort study compared the risk of traumatic brain injury in patients with and without bipolar disorder. We compared 1017 patients with bipolar disorder who received inpatient treatment and 9080 compared patients. The annual incidence rate of traumatic brain injury was calculated as the number of new cases divided by the total number of person-years in the available records. The incidence of subsequent traumatic brain injury was significantly higher in the bipolar group than in control group. The adjusted hazard ratio for those with multiple hospitalizations was higher than the counterpart. Except for patients in the 50-59-year age group, those in all other age groups had higher risks of traumatic brain injury. Our findings reveal a higher risk of traumatic brain injury in patients with bipolar disorder. Patients with recurrent hospitalization and multiple psychotropic use had an increased risk of traumatic brain injury. Age may modify the risk of traumatic brain injury, with a higher risk in middle-aged patients.

[PMID: 28810176 DOI: 10.1016/j.jad.2017.08.007] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2017] [Revised: 07/11/2017] [Accepted: 08/09/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND The influence of gender on inpatient treatment patterns in bipolar patients is unclear. The aim of this study is to examine whether differences in length of stay and frequency of inpatient episodes, according to ICD-10 bipolar disorder (BD)-subgroups, exist between men and women. METHODS All episodes of a manic (F31.0-2), depressive (F31.3-5) or mixed (F31.6) subtype of BD during an inpatient stay in an Austrian hospital in the period of 2001-2014 were included in this study. Data on episodes was provided by the national statistics agency. Weekly admission rates per 100,000 people were calculated by directly age-standardized rates. RESULTS The database comprised 60,607 admissions (35.8% men). The number of inpatient episodes was significantly higher (p < 0.001) in women in all BD subgroups. Average length of stay in manic (p < 0.001) and depressive (p < 0.001) episodes was shorter in women compared to men. No difference could be found for mixed episodes. LIMITATIONS Only aggregated patient data and no single case histories were available for this study. CONCLUSIONS The current study reveals relevant gender differences regarding inpatient treatment patterns, as women were overrepresented in all BD-subgroups. Despite equal life time prevalence, severe mood episodes lead more often to hospitalisations in women. There is a high necessity to further research the underlying causes of these findings.
