Hippocampal Pyk2 regulates specific social skills: Implications for schizophrenia.

Pyk2 has been shown previously to be involved in several psychological and cognitive alterations related to stress, Huntington's disease, and Alzheimer's disease. All these disorders are accompanied by different types of impairments in sociability, which has recently been linked to improper mitochondrial function. We hypothesize that Pyk2, which regulates mitochondria, could be associated with the regulation of mitochondrial dynamics and social skills. In the present manuscript, we report that a reduction of Pyk2 levels in mouse pyramidal neurons of the hippocampus decreased social dominance and aggressivity. Furthermore, social interactions induced robust Pyk2-dependent hippocampal changes in several oxidative phosphorylation complexes. We also observed that Pyk2 levels were increased in the CA1 pyramidal neurons of schizophrenic subjects, occurring alongside changes in different direct and indirect regulators of mitochondrial function including DISC1 and Grp75. Accordingly, overexpressing Pyk2 in hippocampal CA1 pyramidal cells mimicked some specific schizophrenia-like social behaviors in mice. In summary, our results indicate that Pyk2 might play a role in regulating specific social skills likely via mitochondrial dynamics and that there might be a link between Pyk2 levels in hippocampal neurons and social disturbances in schizophrenia.

The Night and Day Challenge of Sleep Disorders and Insomnia: A Narrative Review.

This is a narrative review of sleep disorders, especially chronic insomnia, as a primary diagnosis or as a comorbid diagnosis associated with different psychiatric and organic diseases. The epidemiological evidence is reviewed, the diagnostic criteria most frequently used in clinical practice are examined, and a series of therapeutic recommendations for the correct treatment of this pathology is presented. Sleep disorders are very prevalent in the general population (one-third experiences difficulty with sleep initiation/maintenance at least once a week, and about 6-15% meet the criteria for insomnia disorders), but remain relatively poorly understood and frequently overlooked by healthcare professionals. Prevalence estimates of insomnia disorder vary between 5% and 20%. Sleep disorders co-exist with psychiatric and medical conditions with an interactive and bidirectional relationship. About 70-80% of psychiatric patients show some sleep disturbance and there is a correlation between the severity of the sleep disturbance and the severity of the psychopathology. Untreated sleep disorders increase the risk of cardiovascular events, cognitive impairment, motor vehicle accidents, obesity, diabetes, and efficiency and safety at work, leading to increased all-cause healthcare utilization and being a strong predictor of sick leave or disability pension and poor quality of life. Sleep disorders can cause drowsiness or excessive daytime sleepiness, which can lead to functional impairment in 15% of the general adult population. Sleep quality should be a routine target in the evaluation of patients with psychiatric and non-psychiatric diseases to ensure sleep health based on early diagnosis and adequate therapeutic approaches.

Impact of cognitive reserve in clinical, neurocognitive and lifestyle factors in chronic schizophrenia and early stages of schizophrenia.

INTRODUCTION: Although there is evidence that higher cognitive reserve (CR) is a protective factor and it has been related to better prognosis, there have been no studies to date that have explored the CR level and its impact in clinical, neurocognitive and lifestyle outcomes according to the stage of the disease: early stage of psychosis (ESP) or chronic schizophrenia (SCZ). MATERIAL AND METHODS: A total of 60 patients in the ESP and 225 patients with SCZ were enrolled in the study. To test the predictive capacity of CR for each diagnostic group, a logistic regression analysis was conducted. Hierarchical linear regression analyses were performed to explore the associations between CR and different outcomes. The mediation analyses were performed according to the principles of Baron and Kenny. RESULTS: Patients with SCZ showed lower CR than those in the ESP (p<0.001). CR correctly classified 79.6% of the cases (p<0.001; Exp(B)=1.062). In ESP group, CR was related to working memory (p=0.030) and negative symptoms (p=0.027). CR (t=3.925, p<0.001) and cannabis use (t=2.023, p=0.048) explained 26.7% of the variance on functioning (p=0.003). In patients with SCZ, CR predicted all cognitive domains, negative symptoms (R2=0.091, p=0.001) and functioning (R2=0.074, p=0.005). In both ESP and SCZ groups, higher CR was associated with lower body mass index and circumference. In ESP group, the effect of adherence to Mediterranean diet on functioning (p=0.037) was mediated by CR level (p=0.003). CONCLUSIONS: The implications of CR depend on the stage of the disease (ESP vs. SCZ), with a greater effect on neurocognition and negative symptoms in patients with chronic SCZ.

From gut to brain: A network model of intestinal permeability, inflammation, and psychotic symptoms in schizophrenia.

Impaired intestinal permeability has recently been suggested as a possible source of chronic inflammation in schizophrenia, but its association with specific psychopathological features remains uncertain. This study aimed to explore the interaction between intestinal permeability, inflammation, and positive and negative symptoms in schizophrenia using a network analysis approach. The study sample comprised 281 adults with schizophrenia (age 40.29 ± 13.65 years, 63.0 % males), enrolled in a cross-sectional observational study assessing intestinal permeability. We estimated the network with a Gaussian graphical model, incorporating scores from 14 individual items of the Positive and Negative Syndrome Scale (PANSS), along with body mass index (BMI), and plasma C-reactive protein (CRP) and lipopolysaccharide-binding protein (LBP) levels. We calculated strength centrality and expected influence and used bridge centrality statistics to identify the bridge nodes. Distinct but highly interconnected clusters emerged for positive and negative symptoms. The biological variables were closely associated with each other. LBP was positively linked with CRP and BMI, but only indirectly connected to psychopathology. CRP exhibited direct positive relationships with various PANSS items and bridged LBP and BMI with psychopathology. Bridge nodes included Conceptual Disorganisation (P2), Active Social Avoidance (G16), Suspiciousness/Persecution (P6), and CRP. These findings support the role of gut-derived inflammation as a mechanism underlying greater symptom severity in schizophrenia and emphasise the importance of addressing dietary habits not only to enhance physical health but also to contribute to improving psychotic symptoms.

Spanish validation of the Empirically Developed Clinical Staging Model (EmDe-5) for patients with bipolar disorder.

INTRODUCTION: Bipolar disorder (BD) has been reconceptualised as a progressive disorder that develops from mild to severe presentations. An empirical staging model - the Empirically Developed Clinical Staging Model for BD (EmDe-5) - was developed in a previous study. This study aims to further validate that model using a larger and more representative Spanish sample. MATERIAL AND METHODS: 183 BD outpatients were recruited at 11 sites in Spain. Assessment included clinical characteristics of the BD (number of hospitalisations, number of suicide attempts, comorbid personality disorders), physical health (BMI, metabolic syndrome, number of physical illnesses), cognition (SCIP), functioning (permanently disabled due to BD, FAST), and quality of life (SF-36). The CGI-S, VAS-S, and psychopharmacological treatment pattern were used as external validators. RESULTS: Ten patients (51.5%) were classified as stage 1, 33 (18%) as stage 2, 93 (508%) as stage 3, 37 (202%) as stage 4, and 10 (55%) as stage 5. All profilers, other than number of suicide attempts (p=0.311) and comorbid personality disorder (p=0.061), exhibited worse scores from stage 1 to 5. As expected, VAS-S and CGI-S scores were worse in the later stages. Regarding treatment, early stages (1-2) were associated with the use of one to three drugs while late stages (4-5) were associated with four or more drugs (p=0.002). CONCLUSIONS: We confirm the EmDe-5 staging model's construct validity. The ease of obtaining the profilers, together with the operational criteria provided to quantify them, will facilitate the use of the EmDe-5 staging model in daily clinical practice.

Meta-analysis of the effects of adjuvant drugs in co-occurring bipolar and substance use disorder.

BACKGROUND: Individuals with bipolar disorder (BD) often have co-occurring substance use disorders (SUDs), which substantially impoverish the course of illness. Despite the importance of this dual diagnosis, the evidence of the efficacy and safety of adjuvant treatments is mostly unknown. OBJECTIVE: To perform a meta-analysis to evaluate the efficacy and safety of adjuvant drugs in patients with co-occurring BD and SUD. METHODS: We searched PubMed, Scopus, and Web of Knowledge until 30th April 2022 for randomized clinical trials (RCT) evaluating the efficacy and safety of adjuvant drugs compared to placebo in patients with a dual diagnosis of BD and SUD. We meta-analyzed the effect of adjuvant drugs on general outcomes (illness severity, mania, depression, anxiety, abstinence, substance craving, substance use, gamma-GT, adherence, and adverse events) and used the results to objectively assess the quality of the evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. For completeness, we also report the specific effects of specific adjuvant drugs in patients with specific substance disorders. RESULTS: We included 15 RCT studies (9 alcohol, 3 cocaine, 2 nicotine, and 1 cannabis) comprising 628 patients allocated to treatment and 622 to placebo. There was low-quality evidence that adjuvant drugs may reduce illness severity (g=-0.25, 95% CI: -0.44, -0.06), and very-low quality evidence that they may decrease substance use (g=-0.23, 95% CI: -0.44, -0.02) and increase substance abstinence (g=0.21, 95% CI: 0.04, 0.38). DISCUSSION: There is low-quality evidence that adjuvant drugs may help reduce illness severity, probably via facilitating abstinence and lower substance use. However, the evidence is weak; thus, these results should be considered cautiously until better evidence exists.

The Impact of COVID-19 Lockdown on Adults with Major Depressive Disorder from Catalonia: A Decentralized Longitudinal Study.

The present study analyzes the effects of each containment phase of the first COVID-19 wave on depression levels in a cohort of 121 adults with a history of major depressive disorder (MDD) from Catalonia recruited from 1 November 2019, to 16 October 2020. This analysis is part of the Remote Assessment of Disease and Relapse-MDD (RADAR-MDD) study. Depression was evaluated with the Patient Health Questionnaire-8 (PHQ-8), and anxiety was evaluated with the Generalized Anxiety Disorder-7 (GAD-7). Depression's levels were explored across the phases (pre-lockdown, lockdown, and four post-lockdown phases) according to the restrictions of Spanish/Catalan governments. Then, a mixed model was fitted to estimate how depression varied over the phases. A significant rise in depression severity was found during the lockdown and phase 0 (early post-lockdown), compared with the pre-lockdown. Those with low pre-lockdown depression experienced an increase in depression severity during the "new normality", while those with high pre-lockdown depression decreased compared with the pre-lockdown. These findings suggest that COVID-19 restrictions affected the depression level depending on their pre-lockdown depression severity. Individuals with low levels of depression are more reactive to external stimuli than those with more severe depression, so the lockdown may have worse detrimental effects on them.

Intestinal permeability and low-grade chronic inflammation in schizophrenia: A multicentre study on biomarkers. Rationale, objectives, protocol and preliminary results.

BACKGROUND: Altered intestinal permeability and low-grade chronic inflammation disrupt the integrity of the blood-brain barrier (microbiota-gut-brain axis), probably playing a role in the pathophysiology of schizophrenia-spectrum disorders. However, studies assessing the microbiota-gut-brain axis are inconsistent. This article describes the rationale, objectives, protocol, and presents descriptive results for a new project. METHODS: The sample of this study came from an observational, cross-sectional and multisite study including four centers in Spain (PI17/00246) recruiting adult patients with DSM-5 schizophrenia-spectrum disorders at any stage of the disease. The aims of the project are to assess the interrelation between intestinal permeability and low-grade chronic inflammation in schizophrenia-spectrum disorders and the role of peripheral biomarkers, diet, exercise, metabolic syndrome, disease severity and functioning as well as cognition. Assessments included the following variables: (1) anthropometric, (2) intestinal permeability, diet, and physical exercise, (3) clinical and functional, (4) neuropsychological and cognitive reserve, and (5) peripheral biomarkers from blood. RESULTS: A total of 646 patients were enrolled (257, 39.7% female). Mean age was 43.2±13.6 years, illness duration 15.1±11.5 years. 55.8% consumed tobacco. Positive PANSS score was 13.68±6.55, and 20.38±8.69 in the negative symptoms. CGI was 4.16±2.22 and GAF was 60.00±14.84. CONCLUSION: The results obtained by this project are expected to contribute toward the understanding of the physiopathology of schizophrenia-spectrum disorders. This will likely aid to personalize treatments in real-world clinical practice, potentially including variables related to intestinal permeability and inflammation.

Maternity in women with schizophrenia and schizoaffective disorder.

PURPOSE: Maternity rates in women with schizophrenia have tripled in the past decades, with a current percentage similar to the general population (50-60%). However, mothers with schizophrenia present higher rates of single marital status, and social dysfunction than the general population. In addition, the incidence of unplanned pregnancy, abortions, miscarriages and obstetric complications is higher. This study aimed to describe variables related to maternity in this population. METHODS: One-hundred and ninety-two outpatient women diagnosed with schizophrenia and schizoaffective disorders were included (DSM-IV-TR criteria) in a two-site study. Psychosocial risk factors, demographic variables and clinical features were recorded in the same visit. Non-parametric tests were used in order to describe variables for likelihood offspring in psychotic women. RESULTS: One-hundred and forty-seven (76.6%) women suffered from schizophrenia and 45 (23.4%) schizoaffective disorder. Psychotic mothers used to be married/having a partner and presented a later onset of the illness (over 36 years old) compared to non-mothers. In addition, mothers generally presented pregnancy before the onset of illness. Regarding obstetric complications, around the 80% of the sample presented at least one obstetric complication. Although desire or wish of pregnancy was reported in 66.3% of the mothers, rates of planned pregnancy were 25% and only the 47.9% were currently taking care of their children with their husband/partner. CONCLUSION: Maternity rate is high in this population. This study highlights the need to promote reproductive health care for women with mental disorders and to consider their reproductive life plan. Later onset of disease and being married are potential predictors of maternity in our sample of women with a schizophrenia and schizoaffective disorders while only the half were caring their children at the moment of the evaluation.

Biopsychosocial Response to the COVID-19 Lockdown in People with Major Depressive Disorder and Multiple Sclerosis.

BACKGROUND: Changes in lifestyle, finances and work status during COVID-19 lockdowns may have led to biopsychosocial changes in people with pre-existing vulnerabilities such as Major Depressive Disorders (MDDs) and Multiple Sclerosis (MS). METHODS: Data were collected as a part of the RADAR-CNS (Remote Assessment of Disease and Relapse-Central Nervous System) program. We analyzed the following data from long-term participants in a decentralized multinational study: symptoms of depression, heart rate (HR) during the day and night; social activity; sedentary state, steps and physical activity of varying intensity. Linear mixed-effects regression analyses with repeated measures were fitted to assess the changes among three time periods (pre, during and post-lockdown) across the groups, adjusting for depression severity before the pandemic and gender. RESULTS: Participants with MDDs (N = 255) and MS (N = 214) were included in the analyses. Overall, depressive symptoms remained stable across the three periods in both groups. A lower mean HR and HR variation were observed between pre and during lockdown during the day for MDDs and during the night for MS. HR variation during rest periods also decreased between pre- and post-lockdown in both clinical conditions. We observed a reduction in physical activity for MDDs and MS upon the introduction of lockdowns. The group with MDDs exhibited a net increase in social interaction via social network apps over the three periods. CONCLUSIONS: Behavioral responses to the lockdown measured by social activity, physical activity and HR may reflect changes in stress in people with MDDs and MS. Remote technology monitoring might promptly activate an early warning of physical and social alterations in these stressful situations. Future studies must explore how stress does or does not impact depression severity.

Guía de práctica clínica para el tratamiento farmacológico y psicológico de los pacientes adultos con un trastorno del espectro esquizofrénico y un diagnóstico comórbido de trastorno por uso de sustancias / Clinical practice guideline on pharmacological and psychological management of adult patients with schizophrenia spectrum disorders and a comorbid substance use

Aunque el correcto diagnóstico y manejo de los pacientes con esquizofrenia y un diagnóstico comórbido de trastorno por uso de sustancias (TUS) determinaría una disminución de la morbilidad y mortalidad en estos pacientes, el desarrollo de estrategias terapéuticas eficientes es todavía una asignatura pendiente. Presentamos recomendaciones sobre el manejo farmacológico y psicológico de estos pacientes siguiendo la estructura PICO (Paciente-Intervención-Comparación-Outcome/resultados). Realizamos una evaluación de la calidad de los estudios y un resumen de la evidencia para cada pregunta siguiendo las recomendaciones del grupo de trabajo GRADE («Grading of Recommendations, Assessment, Development and Evaluation»).(AU)

Although correct diagnosis and management of patients with schizophrenia and a comorbid substance use disorder (SUD) would determine a decrease in morbidity and mortality in these patients, development of efficient therapeutic strategies is still pending. We present recommendations on the pharmacological and psychological management of these patients following the ‘PICO’ structure (Patient-Intervention-Comparison-Outcomes). Evaluation of the quality of studies and summary of the evidence for each question was performed following the recommendations of the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) working group.(AU)

Guía de práctica clínica para el tratamiento farmacológico y psicológico de los pacientes adultos con trastorno bipolar y un diagnóstico comórbido de trastorno por uso de sustancias / Clinical practice guideline on pharmacological and psychological management of adult patients with bipolar disorder and comorbid substance use

Esta revisión resume las intervenciones farmacológicos y psicosociales que se han realizado en trastorno bipolar (TB) y un diagnóstico comórbido de trastorno por uso de sustancias (TUS) y además proporciona recomendaciones clínicas respecto de cuáles elementos de intervención son útiles para hacer frente a los síntomas del uso de sustancias versus los síntomas de estado de ánimo en pacientes con estas afecciones concurrentes. Se utilizó la mejor evidencia de ensayos controlados aleatorizados para evaluar las opciones de tratamiento. La fuerza de las recomendaciones se describió mediante el enfoque GRADE. Muy pocos de los ensayos aleatorizados realizados hasta la fecha han proporcionado evidencia consistente para el manejo tanto de los síntomas de estado de ánimo como del uso de sustancias en pacientes con TB. No hay disponibilidad de ensayos clínicos para pacientes con TB que utilizan el cannabis. Algunos tratamientos han mostrado beneficios para los síntomas de estado de ánimo sin beneficios para el uso de alcohol o sustancias ilícitas.(AU)

This review synthesizes the pharmacological and psychosocial interventions that have been conducted in comorbid bipolar disorder (BD) and substance use disorders (SUDs) while also providing clinical recommendations about which intervention elements are helpful for addressing substance use versus mood symptoms in patients with these co-occurring conditions. The best evidence from randomized controlled trials was used to evaluate treatment options. The strength of recommendations was described using the GRADE approach. Very few of the randomized trials performed so far have provided consistent evidence for the management of both mood symptoms and substance use in patients with a BD. No clinical trials are available for bipolar patients using cannabis. Some treatments have shown benefit for mood symptoms without benefits for alcohol or illicit substance use.(AU)

Guía de práctica clínica para el tratamiento farmacológico y psicológico de los pacientes adultos con un trastorno de ansiedad y un diagnóstico comórbido de trastorno por uso de sustancias / Clinical practice guideline on pharmacological and psychological management of adult patients with an anxiety disorder and comorbid substance use

Esta revisión resume las intervenciones farmacológicos y psicosociales que han sido llevadas a cabo en trastornos de ansiedad con un diagnóstico comórbido de trastorno por uso de sustancias y además proporciona recomendaciones clínicas respecto de cuáles elementos de intervención son útiles para hacer frente a los síntomas del uso de sustancias y los síntomas de ansiedad en pacientes con estas afecciones concurrentes. Se utilizó la mejor evidencia de ensayos controlados aleatorizados para evaluar las opciones de tratamiento. La fuerza de las recomendaciones se describió mediante el enfoque GRADE. Hay ensayos clínicos disponibles únicamente para el trastorno por estrés postraumático (TEPT) y para el trastorno de ansiedad. En cuanto al diagnóstico comórbido de trastorno por uso de sustancias, todos los estudios han incluido pacientes con consumo de alcohol, ninguno de ellos ha abordado el consumo de cocaína, cannabis o nicotina. Aunque algunos tratamientos han mostrado beneficios para los síntomas de ansiedad sin beneficios para el consumo de alcohol u otras sustancias, solo se han ensayado enfoques farmacológicos limitados (sertralina, desipramina, paroxetina, buspirona, naltrexona y disulfiram).(AU)

This review synthesizes the pharmacological and psychosocial interventions that have been conducted in comorbid anxiety disorders and SUDs while also providing clinical recommendations about which intervention elements are helpful for addressing substance use versus anxiety symptoms in patients with these co-occurring conditions. The best evidence from randomized controlled trials was used to evaluate treatment options. The strength of recommendations was described using the GRADE approach. Clinical trials are only available for post-traumatic stress disorder (PTSD) and for social anxiety. Concerning the comorbid substance use, all the studies have included patients with alcohol use, none of them have dealt with cocaine, cannabis or nicotine use. Although some treatments have shown benefit for anxiety symptoms without benefits for alcohol or other substance use, only limited pharmacological approaches have been assayed (sertraline, desipramine, paroxetine, buspirone, naltrexone and disulfiram).(AU)

La evidencia actual confirma la alta comorbilidad entre el trastorno por déficit de atención con hiperactividad (TDAH) y trastorno por uso de sustancias (TUS). Esta revisión resume las intervenciones farmacológicas y psicosociales que se han evaluado en pacientes con TDAH y TUS, y ofrece recomendaciones mediante el enfoque GRADE. Nuestros resultados sugieren: 1) En pacientes con TDAH y trastorno por uso de alcohol, la atomoxetina es recomendable para reducir los síntomas de TDAH (recomendación débil) y el craving de alcohol (recomendación débil). 2) En pacientes con TDAH y trastorno por uso de cannabis, la atomoxetina es recomendable para mejorar los síntomas de TDAH (recomendación débil), no para reducir el uso de cannabis (recomendación débil). 3) En pacientes con TDAH y trastorno por uso de cocaína, el metilfenidato no es recomendable para mejorar los síntomas de TDAH o para reducir el uso de cocaína (recomendación débil). 4) En pacientes con TDAH y trastorno por uso de nicotina, es recomendable el metilfenidato para mejorar los síntomas de TDAH (recomendación débil). Los psicoestimulantes, como metilfenidato o lisdexanfetamina, no son recomendables para reducir el uso de nicotina (recomendación débil). 5) Respecto de los pacientes con TDAH y cualquier TUS, el uso de los psicoestimulantes es recomendable para mejorar los síntomas de TDAH (recomendación débil), no para reducir el uso de sustancias (recomendación débil) o para mejorar la retención del tratamiento (recomendación fuerte).(AU)

Substantial evidence has confirmed the high comorbidity between Attention-Deficit/Hyperactivity Disorder (ADHD) and a substance use disorder (SUD). This review synthesizes the pharmacological and psychosocial interventions conducted in ADHD and SUDs, and provides clinical recommendations using the GRADE approach. Our results suggest: 1) In patients with ADHD and alcohol use, atomoxetine is recommended to reduce ADHD symptoms (weak recommendation) and alcohol craving (weak recommendation). 2) In patients with ADHD and cannabis use disorder, atomoxetine is recommended to improve ADHD symptoms (weak recommendation), not to reduce cannabis use (weak recommendation). 3) In patients with ADHD and cocaine use disorder, methylphenidate is not recommended to improve ADHD symptoms or to reduce cocaine use (weak recommendation). 4) In patients with ADHD and comorbid nicotine use disorder, methylphenidate is recommended to improve ADHD symptoms (weak recommendation). Psychoestimulants, such as methylphenidate or lisdexamfetamine dimesylate, are not recommended to reduce nicotine use (weak recommendation). 5) Regarding patients with ADHD and any SUD, the use of psychostimulants is recommended to improve ADHD symptoms (weak recommendation), not to reduce substance use (weak recommendation) or to improve retention to treatment (strong recommendation).(AU)

Affective temperaments and sexual functioning in euthymic patients with bipolar disorder.

Sexual functioning in bipolar disorder (BD) is dependent on multiple clinical and demographic determinants that can eventually lead to sexual dysfunction. However, the contribution of affective temperaments remains unstudied in this population. In this cross-sectional multicentric work, we studied the impact of temperament traits on sexual functioning in 100 euthymic BD outpatients treated only with mood stabilizers with or without benzodiazepines. Temperament was evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego - Autoquestionnaire (TEMPS-A) and sexual functioning with the Changes on Sexual Functioning Questionnaire (CSFQ-14). The effect of temperament on sexual functioning was analyzed using Bayesian ordinal regression models, which included age, gender, BD type, dominant polarity, metabolic syndrome, marital status, and affective symptomatology. Our results showed that hyperthymic traits predicted a significantly higher CSFQ-14 score for global sexual functioning (OR = 1.222; 95% CI [1.073, 1.431]), desire (OR = 1.164; 95% CI [1.025, 1.357]), arousal (OR = 1.278; 95% CI: [1.083, 1.551]), and orgasm (OR = 1.182; 95% CI [1.037, 1.365]). We did not find a significant contribution for other types of temperaments. Better sexual functioning was also associated with a better quality of life. Our findings highlight the importance of temperament traits in sexual functioning in euthymic BD, which may have implications in sexual dysfunction prevention.
