RESUMO

BACKGROUND: Although a large variety of antidepressants agents (AD) with different mechanisms of action are available, no significant differences in efficacy and safety have been shown. However, there have been few attempts to incorporate data on subjective experiences under different AD. METHOD: We conducted a qualitative and quantitative analysis of the posts from the website www.askapatient.com from different AD. We reviewed a random sample of 1000 posts. RESULT: After applying the inclusion and exclusion criteria, we included a final sample of 450 posts, 50 on each of the most used AD: sertraline, citalopram, paroxetine, escitalopram, fluoxetine, venlafaxine, duloxetine, mirtazapine, and bupropion. Bupropion, citalopram, and venlafaxine had the higher overall satisfaction ratings. Sertraline, paroxetine, and fluoxetine had high reports of emotional blunting, while bupropion very few. Overall satisfaction with AD treatment was inversely associated with the presence of the following side-effects: suicidality, irritability, emotional blunting, cognitive disturbances, and withdrawal symptoms. After adjusting for confounders, only emotional blunting was shown to be more frequently reported by users of serotonergic agents, as compared to non-serotoninergic agents. CONCLUSION: This research points out that the subjective experience of patients under treatment should be taken into consideration when selecting an AD as differences between agents were evident. In contrast to the more frequent treatment decisions, users might prefer receiving a non-serotoninergic agent over a serotonergic one due to their lower propensity to produce emotional blunting.

RESUMO

In low- and middle-income countries, there is an increase in the percentage of aging population similar to or greater than that of high-income countries (World Population Ageing 1950-2050, UN, 2001). The emerging health and economical challenges due to these demographic changes will have to be addressed by their health systems. In this context, an adequate training of available human resources in geriatric psychiatry/psychogeriatrics (GP/PG) should be an essential step to meet those challenges.

RESUMO

This letter is written in response to a review recently published in the journal. The aim is to highlight a potential methodological limitation common to many studies comparing bipolar patients with few previous episodes versus those with multiple episodes, and in which the results are interpreted as indicating the longitudinal course of the illness.

RESUMO

The aim of this study was to assess the long-term functional outcome of patients with bipolar disorder (BD). At baseline and after a follow-up period of at least 48 months, three measures of functioning were administered: psychosocial functioning (GAF), employment status (full-time, part-time, and unemployment/disability), and a self-reported measure of functional recovery. At baseline, patients with more than five previous affective episodes exhibited poorer outcomes on all measures of functioning than patients with less than five previous episodes. However, along a mean follow-up period of 77 months, measures of functioning tended to remain stable or improved slightly. These results highlight the limitation of studies comparing measures of functioning between patients with many and few episodes to evaluate functional outcome. Likewise, these preliminary results do not support the hypothesis that functional outcome deteriorates over the course of BD.

RESUMO

BACKGROUND: Behavioral and emotional adverse events induced by drugs commonly prescribed to patients with bipolar disorders are of paramount importance to clinical practice and research. However, no reviews on the topic have been published so far. METHODS: An extensive search was performed. Reports were reviewed if they described behavioral side effects related to pharmacological treatments for bipolar disorders in healthy subjects or patients with different neuropsychiatric disorders. For this review, lithium, antipsychotics, anticonvulsants and selective serotonin reuptake inhibitors were included. RESULTS: Apathy or emotional blunting, diminished sexual desire, and inability to cry were reported to be associated with exposure to selective serotonin reuptake inhibitors. Neuroleptic-induced deficit syndrome/emotional detachment and obsessive-compulsive symptomatology and decision-making modifications. A lithium-related amotivational syndrome was also reported in the literature. Furthermore, hypersexuality and obsessive-compulsive symptoms have been noted in subjects treated with lamotrigine. LIMITATIONS: Primary studies on drug-related adverse events are scant so far and most of the data currently available derive from case reports. Moreover, most of the evidence reviewed is based on studies performed on healthy subjects and patients with neuropsychiatric conditions other than bipolar disorders. DISCUSSION: There is a remarkable dearth of data on behavioral adverse events of pharmacological treatment for bipolar disorders. However, the pieces of evidence available at present, though scant and scattered, suggest that different behavioral adverse events may be related to pharmacological treatment for these disorders. The implications of these findings for research and management of patients with mood disorders are discussed.

RESUMO

The aim of this study was to investigate sexual health and sexual risk behaviors for sexually transmitted infections (STI) among women with bipolar disorder (BDW). Sixty-three euthymic women diagnosed with bipolar disorder type I, II or not otherwise specified were included and matched with a control group of 63 healthy women. Demographic and clinical data, structured sexual health measures and extensive assessment of sexual risk behavior were obtained and compared between groups. BDW had casual partners, were in non-monogamous sexual partnerships and had sex with partners with unknown HIV condition more frequently than healthy control women. History of two or more STI was more frequent among BDW. Inclusion of sexual behavior risk assessment among BDW in treatment is necessary to better identify those women with higher risk for STI and to take measures to improve their sexual health.

RESUMO

Abstract Background In recent years, growing interest in the neuropsychology of bipolar disorder has emerged, giving rise to the accumulation of a robust body of evidence on this topic and to several related questions. Objective To provide a state-of-the-art overview of the neuropsychological profile of bipolar disorder. Method A thorough literature search was performed. Published research evidence was summarized and organized along three key pathways: findings from cross-sectional studies of cognition in bipolar patients, cognitive heterogeneity among affected subjects, and trajectory of neuropsychological deficits. Results At least two thirds of bipolar patients display neuropsychological deficits, even in euthymia. Although bipolar disorder was found to be associated with an increased risk of dementia, data from elderly subjects and longitudinal research do not support a worsening of cognitive performance over time. Discussion Cognitive dysfunctions are part of the clinical conceptualization of bipolar illness. However, they may not be present in all affected subjects and their course appears to be stable in most cases. Available evidence may be highlighting the fact that bipolar disorder is characterized by remarkable heterogeneity regarding cognitive outcomes. Different variables may be related to such heterogeneity and should be the focus of therapeutic approaches and further research.

RESUMO

BACKGROUND: The aim of this study was to investigate reproductive health and level of planning of pregnancies among women with bipolar disorder (BDW). METHODS: 63 euthymic women, with bipolar disorder type I, II or not otherwise specified diagnosis, were included and were matched with a control group of 63 healthy women. Demographic and clinical data, structured reproductive health measures and planning level of pregnancies were obtained and compared between groups. RESULTS: Lower level of planning of pregnancies and higher frequency of unplanned pregnancies were found among BDW. Women with bipolar disorder reported history of voluntary interruption of pregnancies more frequent than women from control group. Current reproductive health care showed no differences between groups. LIMITATIONS: Data based on self-report of participants and retrospective nature of some collected measures may be affected by information bias. The pregnancy planning measure has not been validated in this population before. Demographic and clinical characteristics of the sample study limit generalization of these findings. CONCLUSIONS: Adverse reproductive events, as unplanned pregnancies and elective interruption of pregnancies, may be more frequent among BDW. Clinician must be aware of the reproductive health during treatment of young BDW and take measures to improve better family planning access.

RESUMO

OBJECTIVE: Social cognition has been shown to be affected in bipolar disorders, even during euthymia. However, the social cognitive profile of this group of disorders remains to be ascertained, given that such a broad neuropsychological construct has not been systematically examined in bipolar subjects across different tasks. The aim of this study was to quantify the magnitude of patient-control differences for distinct social cognition assessment instruments: the Hinting Task, the Eyes Test, Faux Pas, the Mayer-Salovey-Caruso Emotional Intelligence Test, and emotional labeling using visual stimuli. METHOD: Effect sizes were extracted from studies chosen according to more stringent criteria than previously used in systematic reviews on the topic and pooled by means of meta-analytical procedures. RESULTS: No significant patient-control differences were found for the recognition of three basic emotions (happiness, sadness, and anger). Small but significant effect sizes favoring healthy controls (Hedges׳ g<0.5) were noted for emotional intelligence, the Hinting Task, the Eyes Test, and the recognition of fear, disgust, and surprise. A medium effect size (Hedges' g=0.58) was noted for the Faux Pas Test. LIMITATIONS: The possible effects of other neurocognitive impairments on social cognitive performance could not be explored. CONCLUSION: On average, small-to-moderate differences may exist between euthymic bipolar disorder subjects and healthy controls regarding social cognitive performance, with mental state decoding being more preserved than mental state reasoning. The influence of clinical and neurocognitive variables, which may play an important role in the social cognitive outcomes of these patients, deserves further clarification.

RESUMO

Although bipolar disorder is highly disabling, data from different regions of the world agree on the finding that there is a prolonged diagnostic delay in affected people. Among the main factors that could explain this phenomenon are contemporary conceptualizations of bipolar disorder and diagnostic criteria of the DSM-IV. Moreover, in recent years it has been cautioned about the risk of overdiagnosis of this disorder. In this context, the new edition of the DSM is presented. The modifications included in the DSM-5 regarding the diagnosis of bipolar disorder are described in this paper. Likewise, the practical implications of these changes are discussed.

RESUMO

OBJECTIVE: Persistent cognitive deficits in bipolar disorder represent a major impediment to functional adjustment, but their static or progressive nature remains to be ascertained. The aim of this study was to synthesize findings from longitudinal research in order to examine the trajectory of cognitive impairment in bipolar disorder. METHOD: A literature search was conducted through online databases covering the period between January 1990 and February 2014. Two approaches were undertaken. First, the results of longitudinal studies including neuropsychological assessment of stable bipolar patients at baseline and after a follow-up period of at least one year were meta-analyzed so as to obtain overall test-retest effect sizes for neurocognitive domains. Second, meta-analysis was restricted to longitudinal studies of bipolar patients including a control group. Patients' and controls' overall test-retest effect sizes were compared. RESULTS: Bipolar patients' performance on 14 cognitive measures remained stable after a mean follow-up period of 4.62 years. When meta-analysis was restricted to controlled studies, no patient-control differences were found regarding longitudinal cognitive outcomes. LIMITATIONS: Test-retest differences for medication variables and mood state could not be controlled. Sufficient data were not available to investigate a wider array of neuropsychological domains. Furthermore, most primary studies included relatively short test-restest intervals. CONCLUSION: To date, the available evidence from longitudinal studies is not in accordance with the hypothesis of a progressive nature of cognitive deficits in BD. The implications of this finding for further research are discussed.

RESUMO

OBJECTIVE: Neurocognitive dysfunction is considered as the main predictor of overall outcome of BD. The issue of whether neurocognitive dysfunction in BD is progressive-or not-has become critical in the effort to define staging models for these disorders. Data about cognitive dysfunction evolution are scarce and contradictory. While some studies showed a progressive pattern others have found a stable form of evolution. METHODS: Twenty four patients with BD aged 60 years or older (E-BD), 24 patients with BD aged 40 years or younger (Y-BD) and 20 healthy controls matched by the E-BD group were evaluated with traditional clinical instruments and an extensive neuropsychological battery was completed. We used ANOVA and Chi-squared for comparisons. Raw score of neurocognitive tasks was transformed to standardized Z-score from the normative data of each test to avoid the effect of age. In order to decrease the risk of type I errors, one-way multivariate analysis of variance was conducted. RESULTS: Despite having an illness duration that was 4 times longer, E-BD did not differ in terms of key cognitive domains compared to Y-BD. These data do not support the hypothesis of a progression of cognitive dysfunction due to illness chronicity.

RESUMO

OBJECTIVES: A sizeable body of work has consistently documented that a number of euthymic mixed-age bipolar disorder subjects exhibit prominent impairments in a variety of cognitive domains. By contrast, knowledge about neuropsychological functioning in elderly patients is scant, despite being necessary for the adequate treatment of this population and the understanding of illness evolution. The aim of this study was to combine findings from the available literature in order to examine the pattern and extent of cognitive deficits in euthymic late-life bipolar disorder subjects. METHODS: A literature search was conducted through the online databases PubMed, ScienceDirect, EBSCO, and Wiley-Blackwell, covering the period between January 1990 and April 2012. Effect sizes reflecting patient-control differences for 10 cognitive variables were extracted from selected investigations and combined by means of meta-analytical procedures. RESULTS: No significant patient-control differences were found for global cognitive status as assessed with the Mini-Mental State Examination and the Clock Drawing Test. Significant overall effect sizes (Hedges' g) of between 0.61 and 0.88 were noted for sustained attention, digit span (forwards and backwards), delayed recall, serial learning, cognitive flexibility, and verbal fluency (phonemic and categorical). CONCLUSIONS: The extent of cognitive dysfunction in euthymic late-life bipolar disorder subjects may be, on average, similar to that reported for remitted young adult patients. Larger effect sizes of impairment may be associated with late illness onset. Implications and future directions for research are proposed.

RESUMO

OBJECTIVE: Most neurocognitive studies have not taken into account the fact that older patients with bipolar disorder (BD) are a heterogeneous population. The main goal of this study was to compare neurocognitive performance and extrapyramidal symptoms in older patients with early-onset BD (EO-BD) and late-onset BD (LO-BD). METHODS: Euthymic older patients with EO-BD (n = 20), LO-BD (n = 20), and healthy controls (n = 20) were evaluated with traditional clinical instruments and measures of exposure to psychotropic drugs, as well as extrapyramidal symptoms. All subjects completed an extensive neuropsychological battery. RESULTS: Patients with EO-BD showed poorer performance than healthy controls in two measures of verbal memory and two measures of executive functions, whereas patients with LO-BD exhibited lower performance scores than healthy controls in almost all of the measures assessed. Impairments in the LO-BD group included even neurocognitive domains typically spared in mixed-age patients. Additionally, there was a trend toward displaying higher extrapyramidal symptoms in the LO-BD group compared with both EO-BD and healthy control groups. In both patient groups, psychosocial functioning was related with executive dysfunction and extrapyramidal symptoms. CONCLUSIONS: Patients with LO-BD may have more extensive and severe cognitive impairments, as well as higher vulnerability to extrapyramidal symptoms, compared with patients with EO-BD. Cognitive-motor disturbances may help to explain impairments in daily functioning among older patients with EO-BD and LO-BD during remission.

RESUMO

BACKGROUND: The relationship between neurocognitive impairment and clinical course in bipolar disorder (BD) is inconclusive. The aim of this study was to compare time to recurrence between patients with and without clinically significant cognitive impairment. METHODS: Seventy euthymic patients with BD were included. Based on baseline neurocognitive performance, patients were divided into those with (n=49) and those without (n=21) clinically significant cognitive impairment. Both groups of patients were prospectivelly assessed by a modified life chart method during a mean of 16.3 months. RESULTS: Patients with some cognitive domain compromised had an increased risk of suffering any recurrence (HR: 3.13; CI 95%: 1.64-5.96), hypo/manic episodes (HR: 2.42; CI 95%: 1.13-5.19), or depressive episodes (HR: 3.84, CI 95%: 1.66-8.84) compared with those patients without clinically significant cognitive impairment. These associations remained significant after adjusting for several potential counfounders such as number of previous episodes, time since last episode, clinical subtype of BD, exposure to antipsychotics, and subclinical symptoms. LIMITATIONS: We classified patients as with or without clinically significant cognitive impairment, although deficits in different cognitive domains may not be equivalent in terms of risk of recurrence. CONCLUSIONS: The results did not support the hypothesis that the experience of successive episodes is related to a progressive neurocognitive decline. On the contrary, cognitive impairment could be the cause more than the consequence of poorer clinical course. Alternatively, a specific subgroup of patients with clinically significant cognitive impairment and a progressive illness in terms of counts of recurrence and shortening of wellness intervals might explain the association showed in this study.
