Study Protocol-Coping With the Pandemics: What Works Best to Reduce Anxiety and Depressive Symptoms.

Background: The coronavirus disease 2019 (COVID-19) pandemic and lockdown might increase anxiety and depressive symptoms in most individuals. Health bodies recommend several coping behaviors to protect against such symptoms, but evidence on the relationship between these behaviors and symptoms mostly comes from cross-sectional studies in convenience samples. We will conduct a prospective longitudinal study of the associations between coping behaviors and subsequent anxiety and depressive symptoms during the COVID-19 pandemic in a representative sample of the Spanish general adult population. Methods: We will recruit 1,000 adult participants from all autonomous communities of Spain and with sex, age, and urbanicity distributions similar to those of their populations and assess anxiety and depressive symptoms and coping behaviors using fortnightly questionnaires and real-time methods (ecological momentary assessments) for 1 year. The fortnightly questionnaires will inquire about anxiety and depressive symptoms [General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9)] and the frequency of 10 potential coping behaviors (e.g., follow a routine) during the past 2 weeks. In addition, we will collect several variables that could confound or moderate these associations. These will include subjective well-being [International Positive and Negative Affect Schedule Short Form (I-PANAS-SF) and Satisfaction with Life Scale (SWLS)], obsessive-compulsive symptoms [Obsessive Compulsive Inventory-Revised (OCI-R)], personality and emotional intelligence [International Personality Item Pool (IPIP) and Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF)], sociodemographic factors (e.g., work status, housing-built environment), and COVID-19 pandemic-related variables (e.g., hospitalizations or limitations in social gatherings). Finally, to analyze the primary relationship between coping behaviors and subsequent anxiety and depressive symptoms, we will use autoregressive moving average (ARMA) models. Discussion: Based on the study results, we will develop evidence-based, clear, and specific recommendations on coping behaviors during the COVID-19 pandemic and lockdown. Such suggestions might eventually help health bodies or individuals to manage current or future pandemics.

Age- and gender-related differences in brain tissue microstructure revealed by multi-component T2 relaxometry.

In spite of extensive work, inconsistent findings and lack of specificity in most neuroimaging techniques used to examine age- and gender-related patterns in brain tissue microstructure indicate the need for additional research. Here, we performed the largest Multi-component T2 relaxometry cross-sectional study to date in healthy adults (N = 145, 18-60 years). Five quantitative microstructure parameters derived from various segments of the estimated T2 spectra were evaluated, allowing a more specific interpretation of results in terms of tissue microstructure. We found similar age-related myelin water fraction (MWF) patterns in men and women but we also observed differential male related results including increased MWF content in a few white matter tracts, a faster decline with age of the intra- and extra-cellular water fraction and its T2 relaxation time (i.e. steeper age related negative slopes) and a faster increase in the free and quasi-free water fraction, spanning the whole grey matter. Such results point to a sexual dimorphism in brain tissue microstructure and suggest a lesser vulnerability to age-related changes in women.

Functioning assessment short test (FAST): validity and reliability in adults with Autism Spectrum Disorder.

BACKGROUND: The assessment of functional impairment is crucial both for the diagnosis and the therapeutic approach to autism spectrum disorder (ASD). The purpose of the present study was to evaluate whether the FAST is a reliable and valid tool to assess functional impairment in adults with Level 1 ASD and to study the differences in psychosocial functioning between younger and older adults with ASD. METHODS: A case-control study was carried out in a sample of 150 participants, 71 adults with Level 1 ASD, and 79 adults without psychiatric history records. RESULTS: Results showed good psychometric properties in terms of validity and reliability. Cronbach's alpha for the total scale was .91 and the area under the curve was .98. The study also showed that adults with ASD present different profiles of functional impairment depending on their age: while younger patients present greater impairment in autonomy, older patients show more difficulties in interpersonal relationships. CONCLUSIONS: Our results support the use of the FAST in the evaluation of adaptive functioning in adults with Level 1 ASD.

Efficacy of an integrative approach for bipolar disorder: preliminary results from a randomized controlled trial.

BACKGROUND: Bipolar disorder (BD) represents one of the most therapeutically complex psychiatric disorders. The development of a feasible comprehensive psychological approach to complement pharmacotherapy to improve its clinical management is required. The main objective of the present randomized controlled trial (RCT) was to test the efficacy of a novel adjunctive treatment entitled integrative approach in patients with BD, including: psychoeducation, mindfulness training, and functional remediation. METHODS: This is a parallel two-armed, rater-blind RCT of an integrative approach plus treatment as usual (TAU), v. TAU alone. Participants were recruited at the Hospital Clinic of Barcelona and randomized to one of the two conditions. They were assessed at baseline and after finishing the intervention. The main outcome variable included changes in psychosocial functioning assessed through the Functioning Assessment Short Test (FAST). RESULTS: After finishing the treatment, the repeated-measures analyses revealed a significant group × time interaction in favor of the patients who received the integrative approach (n = 28) compared to the TAU group (n = 37) (Pillai's trace = 0.10; F(1,57) = 6.9; p = 0.01), improving the functional outcome. Significant effects were also found in two out of the six domains of the FAST, including the cognitive domain (Pillai's trace = 0.25; F(1,57) = 19.1; p < 0.001) and leisure time (Pillai's trace = 0.11; F(1,57) = 7.15; p = 0.01). Regarding the secondary outcomes, a significant group × time interaction in Hamilton Depression Rating Scale changes was detected (Pillai's trace = 0.08; F(1,62) = 5.6; p = 0.02). CONCLUSION: This preliminary study suggests that the integrative approach represents a promising cost-effective therapy to improve psychosocial functioning and residual depressive symptoms in patients suffering from BD.

The functioning assessment short test (FAST) applied to first-episode psychosis: Psychometric properties and severity thresholds.

Functional impairment is a defining feature of psychotic disorders. The Functional Assessment Short Test (FAST) is one of the most widely used instruments to measure psychosocial functioning. However, cut-offs of impairment have been well-established for bipolar disorders, but not for other clinical populations. This study aims to analyse psychometric properties of the FAST and establish their corresponding cut-off values for the different severity gradations in a first-episode of non-affective psychosis (FEP) patients. Global Assessment Functioning (GAF) and FAST ratings from 212 non-affective FEP and 204 healthy controls were analyzed. The psychometric properties of FAST (internal consistency, concurrent validity, discriminant validity, factorial analyses and sensitivity to change) were analyzed. The severity gradations of the FAST were defined by the congruence between two grading methods: linear regression analysis (LRA) and percentiles. The FAST showed strong psychometric properties. LRA with the GAF scores yielded the following equation: GAFscore= 80.83 - 0.639*FASTscore. The FAST ranges in non-affective FEP patients derived from LRA and percentiles, were as follows: 0-9 (No impairment); 10-19 (Minimal impairment); 20-34 (Mild impairment); 35-45 (Moderate impairment); 46-72 (Severe impairment). Patients with no functional impairment had a higher socioeconomic status, fewer depressive and negative symptoms, lower severity of illness and higher cognitive reserve level than the others groups. In conclusion, the FAST shows optimal psychometric properties which corroborate its applicability in FEP populations. It is a well-demonstrated valid instrument and the present cut-off scores could be implemented in clinical and research practice to assess properly the psychosocial functional outcome of non-affective FEP populations.

Effects of an integrative approach to bipolar disorders combining psychoeducation, mindfulness-based cognitive therapy and functional remediation: study protocol for a randomized controlled trial / Efectos de un abordaje integral para el trastorno bipolar combinando la psicoeducación, terapia cognitiva basada en el mindfulness y rehabilitación funcional: protocolo para un ensayo clínico controlado y aleatorizado

INTRODUCTION: Bipolar disorder is related to a high level of personal, familial, social and economic burden. There is a need for feasible adjunctive psychological interventions easy to implement in clinical practice in order to enhance aspects that medication alone cannot achieve. This study aims to evaluate the impact of a 12-session adjunctive integrative program designed for patients with bipolar disorder. METHODS: This is a single-blind prospective, randomized controlled trial involving a total of 132 outpatients with bipolar disorder who will be recruited from the Hospital Clinic of Barcelona. All participants will be randomly assigned to two arms. All the patients will receive treatment as usual (TAU) but in addition the experimental group will receive an integrative approach consisting of 12-sessions of 90 min each in which contents of psychoeducation for patients have been combined with a session for family members, and complemented with aspects related to health promotion, mindfulness training, and strategies for cognitive and functional enhancement. The whole sample will be assessed at baseline, after completion (3-months) and at 12 months from baseline regarding demographic and clinical variables, psychosocial and cognitive functioning, wellbeing and quality of life. The primary outcome measure will be improvement in psychosocial functioning. CONCLUSIONS: If the integrative approach is effective, it would allow clinicians to cover different areas that may be affected by bipolar disorder, by means of a brief intervention that can therefore be easily generalized to clinical practice

INTRODUCCIÓN: El trastorno bipolar se asocia a un nivel elevado de carga personal, familiar, social y económica. Existe la necesidad de intervenciones psicológicas complementarias factibles y fáciles de implementar en la práctica clínica para mejorar aspectos que la medicación no consigue alcanzar. Este estudio tiene como objetivo evaluar el impacto de un programa integral de 12 sesiones complementario al tratamiento farmacológico para pacientes con trastorno bipolar. MÉTODOS: Ensayo clínico aleatorizado, controlado, a simple ciego. Serán reclutados del Hospital Clínic de Barcelona 132 pacientes ambulatorios diagnosticados de trastorno bipolar. Los participantes serán asignados aleatoriamente a dos grupos. Todos los pacientes recibirán el tratamiento habitual (TAU) pero, además, el grupo experimental recibirá un abordaje integral que consistirá en 12 sesiones de 90 min en las que se han combinado los contenidos de psicoeducación para pacientes con una sesión para familiares, complementándose con aspectos relacionados con la promoción de la salud, el entrenamiento en atención plena y estrategias para la potenciación cognitiva y funcional. La muestra completa será evaluada al inicio del estudio, a los 3 meses y a los 12 meses de seguimiento respecto a variables sociodemográficas y clínicas, de funcionamiento psicosocial y cognitivo, bienestar y calidad de vida. El principal resultado esperado será la mejoría en el funcionamiento psicosocial. CONCLUSIONES: Si el abordaje integral es efectivo, permitiría a los clínicos cubrir diferentes áreas que pueden verse afectadas por el trastorno bipolar, mediante una breve intervención que, por lo tanto, puede generalizarse fácilmente a la práctica clínica

Family functioning in bipolar disorder: Characteristics, congruity between patients and relatives, and clinical correlates.

Functional improvement has become one of the aims of the treatment of bipolar disorder. However, scant attention has been given to family functioning, even though it has a role in the illness outcome and is affected by the disorder. The aims of this study were to compare family functioning reported by euthymic patients with bipolar disorder and healthy controls; explore the level of congruence in the perception of family environment between patients with bipolar disorder and their relatives; and analyse the relationship between clinical variables and family functioning. The sample comprised 82 adult euthymic subjects with bipolar disorder, 82 family caregivers of these patients and 47 healthy controls. Participants completed the Family Environment Scale. Results showed moderate correlations and a mean pattern almost identical between relatives' and patients' reported scores in family functioning subscales. There were significant differences between patients and controls, favourable for the latter, in the subscales cohesion (p<0.005), expressiveness (p=0.002), conflict (p=0.038), intellectual-cultural orientation (p=0.001), active-recreational orientation (p<0.005), and a non-significant trend in organization (p=0.064). Significant associations were found between family environment and clinical variables of severity. These findings contribute to increasing the understanding of family functioning in bipolar disorder and highlight the importance of family work.

Hyperprolactinemia and medications for bipolar disorder: systematic review of a neglected issue in clinical practice.

Drug-induced changes in serum prolactin (sPrl) levels constitute a relevant issue due to the potentially severe consequences on physical health of psychiatric patients such as sexual dysfunctions, osteoporosis and Prl-sensitive tumors. Several drugs have been associated to sPrl changes. Only antipsychotics have been extensively studied as sPrl-elevating agents in schizophrenia, but the extent to which bipolar disorder (BD) treatments affect sPrl levels is much less known. The objective of this systematic review is to summarize the evidence of the effects of drugs used in BD on Prl. This review followed the PRISMA statement. The MEDLINE/PubMed/Index Medicus, EMBASE, and Cochrane Library databases were systematically searched for articles in English appearing from any time to May 30, 2014. Twenty-six studies were included. These suggest that treatments for BD are less likely to be associated with Prl elevations, with valproate, quetiapine, lurasidone, mirtazapine, and bupropion reported not to change PRL levels significantly and lithium and aripiprazole to lower them in some studies. Taking into account the effects of the different classes of drugs on Prl may improve the care of BD patients requiring long-term pharmacotherapy. Based on the results of this review, lithium and valproate appear to be safer due to their low potential to elevate sPrL; among antipsychotics, quetiapine, lurasidone and aripiprazole appear to be similarly safe.

Predictors of functional outcome after a manic episode.

BACKGROUND: The identification of functional outcome predictors after acute episodes of bipolar disorders (BD) may allow designing appropriate treatment aiming at restoring psychosocial functioning. Our objective was to identify the best functional outcome predictors at a 6-month follow-up after an index manic episode. METHODS: We conducted a naturalistic trial (MANACOR) focusing on the global burden of BD, with special emphasis on manic episode-associated costs. We observed patients with BD seen in services of four hospitals in Catalonia (Spain).The total sample included 169 patients with chronic DSM-IV-TR BD I suffering from an acute manic episode who were followed-up for 6 months. In this subanalysis we report the results of a stepwise multiple regression conducted by entering in the model those clinical and sociodemographic variables that were identified through preliminary bivariate Pearson correlations and using total scores on the Functioning Assessment Short Test (FAST) at the 6-month follow-up as the dependent variable. RESULTS: Number of previous depressive episodes (Beta=3.25; t=3.23; p=0.002), presence of psychotic symptoms during the manic index episode (Beta=7.007; t=2.2; p=0.031) and the Body Mass Index (BMI) at baseline (Beta=0.62; t=2.09; p=0.041) were best predictors of functional outcome after a manic episode. LIMITATIONS: The main limitations of this study include the retrospective assessment of the episodes, which can be a source of bias, and the 6-month follow-up might have been too short for assessing the course of a chronic illness. CONCLUSIONS: Psychotic symptoms at index episode, number of past depressive episodes, and BMI predict worse outcome after 6 months follow-up after a manic episode, and may constitute the target of specific treatment strategies.

Risk factors for rapid cycling in bipolar disorder.

OBJECTIVES: The aim of this study was to investigate the clinical factors associated with the development of rapid cycling, as well as to elucidate the role of antidepressants. METHODS: The present study (NCT01503489) is a prospective, naturalistic cohort study conducted in a sample of 289 patients diagnosed with bipolar disorder followed and treated for up to 14 years. The patients were divided into two groups on the basis of the development of a rapid cycling course (n = 48) or no development of such a course (n = 241), and compared regarding sociodemographic, clinical, and outcome variables. RESULTS: Among the 289 patients, 48 (16.6%) developed a rapid cycling course during the follow-up. Several differences were found between the two groups, but after performing Cox regression analysis, only atypical depressive symptoms (p = 0.001), age at onset (p = 0.015), and number of suicide attempts (p = 0.030) persisted as significantly associated with the development of a rapid cycling course. CONCLUSIONS: The development of rapid cycling during the course of bipolar disorder is associated with a tendency to chronicity, with a poorer outcome, and with atypical depressive symptomatology. Our study also suggests that the development of rapid cycling is associated with a higher use of antidepressants.

Functional remediation for patients with bipolar II disorder: improvement of functioning and subsyndromal symptoms.

Recently, Functional Remediation (FR) has proven to be effective in improving the functional outcome of euthymic bipolar patients. The aim of this study was to test the efficacy of the FR program in a subsample of euthymic bipolar II patients (BPII). A post-hoc analyses were undertaken using data of 53 BPII outpatients who had participated in a multicenter, rater-blind, randomized, controlled trial exploring the efficacy of FR (n=17) as compared with a Psychoeducation group (PSY) (n=19) and a treatment as usual control group (TAU n=17). The primary outcome variable was the functional improvement defined as the mean change in the Functioning Assessment Short Test (FAST) from baseline to endpoint after the intervention. Regarding the treatment effect, data reveal a significant functional improvement from baseline to endpoint, suggestive for an interaction between program pertinence and time (pre-post). Nevertheless, Tukey׳s post-hoc test only revealed a trend in favor of a better outcome for FR when compared to the other two groups. We also found an interaction between program pertinence and time when analysing the subdepressive symptoms, with BPII patients in FR showing a significant reduction when compared to the PSY group. Our results suggest that the FR appears to be effective in improving the overall functional outcome in BPII, as well as in reducing subdepressive symptoms.

Common and specific brain responses to scenic emotional stimuli.

Processing of emotions has been an enduring topic of interest in neuroimaging research, but studies have mostly used facial emotional stimuli. The aim of this study was to determine neural networks involved in emotion processing using scenic emotional visual stimuli. One hundred and twenty photographs from the International Affective Picture System (IAPS), including ecological scenes of disgust, fear, happiness, and sadness, were presented to 40 healthy participants while they underwent functional magnetic imaging resonance (fMRI). Afterwards they evaluated the emotional content of the pictures in an offline task. The occipito-temporal cortex and the amygdala-hippocampal complex showed a non-specific emotion-related activation, which was more marked in response to negative emotions than to happiness. The temporo-parietal cortex and the ventral anterior cingulate gyrus showed deactivation, with the former being marked for all emotions except fear and the latter being most marked for disgust. The fusiform gyrus showed activation in response to disgust and deactivation in response to happiness or sadness. Brain regions involved in processing of scenic emotion therefore resemble those reported for facial expressions of emotion in that they respond to a range of different emotions, although there appears to be specificity in the intensity and direction of the response.

Risk factors for antidepressant-related switch to mania.

OBJECTIVE: Treatment of bipolar depression with antidepressants is strongly debated on the basis of the methodologically poor and insufficient data supporting their use and the widely held belief that antidepressants can induce new episodes of abnormal mood elevation or accelerate the rate of cycling. The present study aimed at identifying clinical risk factors for switch into hypomania, mania, or mixed states, within 8 weeks after introduction of an antidepressant or after increasing its dosage, in a prospective, longitudinal design. METHOD: 221 consecutive DSM-IV-TR depressed bipolar I and II disorder patients were treated with antidepressants, which were added to previously prescribed mood stabilizers and/or atypical antipsychotics. No patient was on antidepressant monotherapy. The patients were enrolled from October 2005 through January 2010. The primary outcome was the assessment of switch to mania or hypomania within 8 weeks after the introduction or dose increase of an antidepressant. Both groups were compared with analysis of variance and χ² procedures. RESULTS: Treatment-emergent affective switch was detected in 54 patients (24.4%) (switch group) while 167 patients (75.6%) (nonswitch group) did not experience a treatment-related switch. The main clinical differences significantly associated with the occurrence of an antidepressant-related switch, after performing logistic regression analysis, were higher rate of previous switches (P < .001) in the switch versus the nonswitch group, lower rate of responses to antidepressants (P < .001) in the switch versus the nonswitch group, and earlier age at onset (P = .026) in the switch versus the nonswitch group. DISCUSSION: Bipolar patients with an earlier age at onset and an illness course characterized by lower rate of response to antidepressants and higher rate of switches into mania or hypomania were found to be the ones with higher switch risk. Nevertheless, a greater number of previous antidepressant exposures was not associated with the occurrence of an antidepressant-associated switch.

Six-month functional outcome of a bipolar disorder cohort in the context of a specialized-care program.

OBJECTIVES: A marked disparity between functional recovery and symptomatic improvement has been demonstrated in bipolar disorder. However, most of the previous studies have been conducted in the United States, and there is little prospective research from Europe on this topic. The main objective of the present six-month follow-up study was to assess functioning in a sample of Spanish bipolar disorder patients following an acute episode or subsyndromal state. Additionally, we also evaluated the sensitivity to change of the Functioning Assessment Short Test (FAST). METHODS: A total of 97 bipolar disorder patients with syndromal (n = 59) or subsyndromal (n = 38) symptoms were evaluated using the 17-item Hamilton Depression Rating Scale and Young Mania Rating Scale. The FAST was the primary measure to assess multiple areas of psychosocial functioning. Functioning was evaluated at four different time periods: baseline, 21 days, three months, and six months. RESULTS: A significant improvement in global functioning was found in the whole sample over the six-month period, as indicated by a reduction of FAST total score (mean ± standard deviation) from 39.97 ± 15.10 to 30.65 ± 16.93 (F = 36.104, p = 0.0001). This was also evident in all areas of functioning studied. However, only 26.4% of remitted patients (n = 42) achieved functional recovery, while 79.6% of the total sample (N = 97) experienced clinical remission of acute symptoms. CONCLUSIONS: Although many patients presented syndromal recovery, only a minority of them achieved favorable functioning in multiple areas, even after specialized mental health care. Furthermore, the FAST scale was sensitive to detect minimal changes in functioning in both short (21 days) and long (6 months) periods, which may be relevant to the use of this scale in clinical trials.

Functional remediation for bipolar disorder.

Neurocognitive impairment constitutes a core feature of bipolar illness. The main domains affected are verbal memory, attention, and executive functions. Deficits in these areas as well as difficulties to get functional remission seem to be increased associated with illness progression. Several studies have found a strong relationship between neurocognitive impairment and low functioning in bipolar disorder, as previously reported in other illnesses such as schizophrenia. Cognitive remediation strategies, adapted from work conducted with traumatic brain injury patients and applied to patients with schizophrenia, also need to be adapted to individuals with bipolar disorders. Early intervention using functional remediation, involves neurocognitive techniques and training, but also psychoeducation on cognition-related issues and problem-solving within an ecological framework.

Gender differences in a cohort study of 604 bipolar patients: the role of predominant polarity.

BACKGROUND: Some clinical differences between gender regarding the course and outcome of bipolar disorders have already been described and some others remain still controversial. AIMS: To explore gender differences regarding clinical and socio-demographic characteristics amongst bipolar patients with particular attention to predominant polarity and depressive symptoms. METHOD: Data were collected from DSM-IV type I and II bipolar patients (n=604), resulting from the systematic follow-up of the Bipolar Disorders Program, Hospital Clinic of Barcelona, over an average follow-up of 10 years. Socio-demographic and clinical variables were collected in order to detect gender-related differences. RESULTS: Bipolar women are more likely than men to show a predominance of depressive polarity as well as a depressive onset whilst men would be more likely to suffer from comorbid substance use disorders. Women significantly have a higher lifetime prevalence of psychotic depression and a higher prevalence of axis II comorbid disorders. Bipolar women are also more likely to have a family history of suicide and a lifetime history of attempted suicide. Suicide attempts are more often violent amongst bipolar men. In a backward logistic regression model, two variables were responsible for most gender-related clinical differences: type of predominant polarity - more likely to be depressive amongst women - (B=-0.794, p=0.027, Exp(B)=0.452; CI= 0.223-0.915), alcohol abuse (B=-1.095, p=0.000, Exp(B)=2990; CI= 1.817-4.919) and cocaine abuse (B=0.784, p=0.033, Exp(B)=2.189; CI= 1.066-4.496) - more prevalent amongst men. CONCLUSION: The main characteristic featuring bipolar women is depression, both at illness onset and as a predominant polarity all along the illness course. This may have important diagnostic and therapeutic implications.

Bipolar mixed episodes and antidepressants: a cohort study of bipolar I disorder patients.

OBJECTIVES: The aim of this study was to elucidate the factors associated with the occurrence of mixed episodes, characterized by the presence of concomitant symptoms of both affective poles, during the course of illness in bipolar I disorder patients treated with an antidepressant, as well as the role of antidepressants in the course and outcome of the disorder. METHOD: We enrolled a sample of 144 patients followed for up to 20 years in the referral Barcelona Bipolar Disorder Program and compared subjects who had experienced at least one mixed episode during the follow-up (n=60) with subjects who had never experienced a mixed episode (n=84) regarding clinical variables. RESULTS: Nearly 40% of bipolar I disorder patients treated with antidepressants experienced at least one mixed episode during the course of their illness; no gender differences were found between two groups. Several differences regarding clinical variables were found between the two groups, but after performing logistic regression analysis, only suicide attempts (p<0.001), the use of serotonin norepinephrine reuptake inhibitors (p=0.041), switch rates (p=0.010), and years spent ill (p=0.022) were significantly associated with the occurrence of at least one mixed episode during follow-up. CONCLUSIONS: The occurrence of mixed episodes is associated with a tendency to chronicity, with a poorer outcome, a higher number of depressive episodes, and greater use of antidepressants, especially serotonin norepinephrine reuptake inhibitors.

Functional impairment and disability across mood states in bipolar disorder.

BACKGROUND: Bipolar disorder (BD) represents a chronic and recurrent illness that can lead to severe disruptions in family, social, and occupational functioning. The severity of mood symptomatology has been associated with functional impairment in this population. However, the majority of studies have assessed global functioning without considering specific domains. The main objective of the current study was to assess specific life domains of functioning as well as the overall functioning in patients with BD across different mood states ([hypo] mania, depression, or euthymia) compared with healthy controls by the means of a standardized scale validated for BD. METHODS: The sample included 131 subjects with BD (68 in remission, 31 hypo [manic], and 32 depressed) and 61 healthy controls. The Functioning Assessment Short Test was used to assess overall and multiple areas of functional impairment (autonomy, occupational functioning, cognitive functioning, interpersonal relationships, financial issues, and leisure time). RESULTS: The results showed significant intergroup differences; depressed patients had the lowest functioning (48.03 ± 12.38) followed by (hypo) manic patients (39.81 ± 13.99). The euthymic group showed least impairment in functioning compared with the depression and (hypo) mania groups (11.76 ± 12.73) but still displayed significant impairment when compared with the healthy control group (5.93 ± 4.43). CONCLUSIONS: This study indicates that depressive symptoms are associated with greater negative impact on psychosocial functioning than (hypo) manic symptoms. Further deficits in functioning seem to persist during remission. The results highlight the importance of aggressively treating depression and mania and the need to develop psychosocial interventions targeting to improve functional outcomes.

Psychotic versus non-psychotic bipolar II disorder.

INTRODUCTION: Psychotic symptoms in bipolar II disorder, allowed by definition only during a depressive episode, are present in a range between 3% and 45%. Little is known regarding the impact of psychotic symptoms on the clinical course of bipolar II patients. Findings from previous reports are controversial and focused specifically on bipolar I disorder. The aim of this study was to ascertain the clinical characteristics of individuals with bipolar II disorder with and without lifetime history of psychotic symptoms. METHODS: The sample consisted of 164 DSM-IV Bipolar II patients consecutively recruited from the Barcelona Bipolar Disorder Program. Patients were divided in Bipolar II patients with (N=32) and without (N=132) lifetime history of psychotic symptoms. Clinical and sociodemographic features were compared. RESULTS: Thirty-two out of 164 patients with bipolar II disorder had a history of psychosis during depression (19.5%). Bipolar II patients with a history of psychotic symptoms showed a higher number of hospitalizations than patients without such a history (p<0.001). They were also older but were less likely to have a family history of bipolar illness and any mental disorder than non-psychotic bipolar II patients. Melancholic and catatonic features were significantly more frequent in psychotic bipolar II patients (p<0.001). CONCLUSIONS: Our findings confirm that the presence of psychotic symptoms in bipolar II disorder is not rare. Psychotic bipolar II disorder may be a different phenotype from non-psychotic bipolar disorder.
