Abstract
Introduction The WHO would increase diagnosis and treatment of viral hepatitis in the world by 2030, based on the high efficacy of direct-acting-antivirals against HCV, extended vaccination programs in HBC, and epidemiological data. Diagnostic of HCV/HBV infection has been simplified by point-of-care (POC) devices (cheap/easy-to-use/interprete/qick-results), detecting anti-HCV-antibodies or HBV-antigen in capillary blood at the patients´site. The current seroprevalence of viral hepatitis B/C in general population in Spain is 0.5%/1% and would be higher (3-17%) in people with severe-mental-disorder due to risk factors and traditionally less access to health care. Objectives To design a screening protocol for HCV eradication and HBV-detection, and risk factors among severe-mental-disorder patients in a CommunityMentalHealthCenter. To guarantee equal access to viral hepatitis screening and therapy among this population. Methods Outpatients visited along one-year who accepts participate. Using POC-device for qualitative detection of anti-HCV-antibodies (Quickview-of-Lumiquick-Diagnostics®)/HBsAG (Abbott-Rapid-Diagnostics®). Socio-demographic data; mental disorder(ICD-10); HCV/HBV risk-factors; Neurotoxicity-scale (mood/cognition/sleep/gastrointestinal/sickness/motor); SF-12; Patient-satisfaction. Subjects with positive HCV/HBV POC-test will have a on-site venopuncture to assess hemograme/liver tests, and HCV-RNA (Cobas-TaqMan-RocheDiagnostics)/HBsAg-ELISA (Atellica-Siemens). In positive HCV-RNA (active infection) the psychiatric-team will inform the hepatology-team for non-invasive liver fibrosis assessment and DAA prescription. The patient will receive 8-12-weeks on-site treatment, and assessed (Neurotoxicity/SF-12).HCV cure will be confirmed by HCV-RNA in blood. Chronic-cases will be managed at Hepatology-Unit. Results We will present the results of the implementation of the programme and their ability to detect viral-hepatitis-positive cases among patients with severe-mental-disorders and to treat them effectively. Conclusions Our results may support the generalisation of the programme in among CMHC’s. Disclosure No significant relationships.

Association of childhood trauma and genetic variability of CRH-BP and FKBP5 genes with suicidal behavior in bipolar patients. J Affect Disord 2019; 255:15-22. [PMID: 31195252 DOI: 10.1016/j.jad.2019.05.014] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 05/03/2019] [Accepted: 05/07/2019] [Indexed: 11/26/2022]
Abstract
BACKGROUND Around 8% of bipolar disorder (BD) patients die by suicide every year, accounting for the highest rate among the psychiatric population. Suicidal behavior (SB) is mediated by an intertwining system of extrinsic and intrinsic factors. Childhood trauma (CT) and gene variants of the stress-management hypothalamic-pituitary-adrenal (HPA) axis have been reported as risk factors for SB. The aim of this study was to elucidate the association of CT and HPA axis genetic variants with SB. METHODS 135 BD patients were recruited for clinical assessment of CT and SB by means of the Childhood Trauma Questionnaire (CTQ) and the Columbia Suicide Severity Rating Scale (C-SSRS), respectively. A total of 28 single nucleotide polymorphisms (SNPs) from 8 HPA axis genes (POMC, NR3C2, CRH-BP, NR3C1, FKBP5, CRHR2, CRHR1, and MC2R) were genotyped. RESULTS The analyses showed an association of total CTQ score (p = 0.003), emotional abuse (p = 0.001), sexual abuse (p = 0.005) and emotional neglect (p = 0.005) with SB. CRH-BP rs7728378-C carriers (p = 0.004; OR = 3.05), FKBP5 rs3777747-AA (p = 0.039; OR = 0.34) and FKBP5 rs2766533-GG genotypes (p = 0.001; OR = 2.93) were associated with SB although only rs2766533 survived multiple test correction. No gene-environment interaction was found. LIMITATIONS The relatively small sample size limits the statistical power to detect smaller environmental and genetic effects. Cross-sectional data collection in psychometric assessments can yield biased data. CONCLUSIONS The present study characterizes novel SB risk factors and replicates previous findings in BD patients. CT and variability in CRH-BP and FKBP5 genes should be further studied for a better understanding of SB and ultimately help in suicide prevention.

Abstract
OBJECTIVE The main aims of this study were to examine the differences in the Emotional Intelligence (EI), the emotional domain of social cognition (SC), between euthymic patients with bipolar disorder (BD) and healthy controls (HC) and to evaluate the contribution of sociodemographic, clinical, and neuropsychological variables to EI. METHODS We recruited 202 patients with BD and 50 HC. EI was evaluated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). The sociodemographic, clinical, and neurocognitive variables that showed a significant association with EI were entered into hierarchical multiple regression analysis. RESULTS BD patients obtained significantly lower scores compared to HC in the Emotional Intelligence Quotient (EIQ) and in the Understanding Emotions branch score. The best fitting model for the variables associated with EI in the patients group was a linear combination of gender, estimated IQ, family history of affective diagnosis, and executive function. The model, including these previous variables, explained up to 27.6% of the observed variance (R2 = 0.276, F = 16.406, P < 0.001). CONCLUSIONS The identification of variables associated with deficit in EI, such as male gender, lower estimated IQ, family history of affective diagnosis. and lower executive function performance, may help in selecting treatment targets to improve SC, and especially EI, in patients with BD.

Association between completed suicide and bipolar disorder: A systematic review of the literature. J Affect Disord 2019; 242:111-122. [PMID: 30173059 DOI: 10.1016/j.jad.2018.08.054] [Citation(s) in RCA: 125] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Revised: 07/25/2018] [Accepted: 08/12/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Completed suicide is a major cause of death in bipolar disorder (BD) patients. OBJECTIVE The aim of this paper is to provide an overall review of the existing literature of completed suicide in BD patients, including clinical and genetic data DATA SOURCES: We performed a systematic review of English and non-English articles published on MEDLINE/PubMed, PsycInfo and Cochrane database (1970-2017). Additional studies were identified by contacting clinical experts, searching bibliographies, major textbooks and website of World Health Organization. Initially we did a broad search for the association of bipolar disorder and suicide and we were narrowing the search in terms included "bipolar disorder" and "completed suicide". STUDY SELECTION Inclusion criteria were articles about completed suicide in patients with BD. Articles exclusively focusing on suicide attempts and suicidal behaviour have been excluded. We used PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) consensus for drafting this systematic review. RESULTS The initial search generated 2806 articles and a total of 61 meeting our inclusion criteria. We reviewed epidemiological data, genetic factors, risk factors and treatment of completed suicide in BD. Suicide rates in BD vary between studies but our analyses show that they are approximately 20-30-fold greater than in general population. The highest risk of successful suicide was observed in BD-II subjects. The heritability of completed suicide is about 40% and some genes related to major neurotransmitter systems have been associated with suicide. Lithium is the only treatment that has shown anti-suicide potential. LIMITATIONS The most important limitation of the present review is the limited existing literature on completed suicide in BD. CONCLUSIONS BD patients are at high risk for suicide. It is possible to identify some factors related to completed suicide, such as early onset, family history of suicide among first-degree relatives, previous attempted suicides, comorbidities and treatment. However it is necessary to promote research on this serious health problem.

Characterizing decision-making and reward processing in bipolar disorder: A cluster analysis. Eur Neuropsychopharmacol 2018; 28:863-874. [PMID: 29807846 DOI: 10.1016/j.euroneuro.2018.04.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 03/22/2018] [Accepted: 04/30/2018] [Indexed: 11/25/2022]
Abstract
The presence of abnormalities in emotional decision-making and reward processing among bipolar patients (BP) has been well rehearsed. These disturbances are not limited to acute phases and are common even during remission. In recent years, the existence of discrete cognitive profiles in this psychiatric population has been replicated. However, emotional decision making and reward processing domains have barely been studied. Therefore, our aim was to explore the existence of different profiles on the aforementioned cognitive dimensions in BP. The sample consisted of 126 euthymic BP. Main sociodemographic, clinical, functioning, and neurocognitive variables were gathered. A hierarchical-clustering technique was used to identify discrete neurocognitive profiles based on the performance in the Iowa Gambling Task. Afterward, the resulting clusters were compared using ANOVA or Chi-squared Test, as appropriate. Evidence for the existence of three different profiles was provided. Cluster 1 was mainly characterized by poor decision ability. Cluster 2 presented the lowest sensitivity to punishment. Finally, cluster 3 presented the best decision-making ability and the highest levels of punishment sensitivity. Comparison between the three clusters indicated that cluster 2 was the most functionally impaired group. The poorest outcomes in attention, executive function domains, and social cognition were also observed within the same group. In conclusion, similarly to that observed in "cold cognitive" domains, our results suggest the existence of three discrete cognitive profiles concerning emotional decision making and reward processing. Amongst all the indexes explored, low punishment sensitivity emerge as a potential correlate of poorer cognitive and functional outcomes in bipolar disorder.

Abstract
OBJECTIVE Our aim was to analyse sociodemographic and clinical differences between non-suicidal (NS) bipolar patients (BP), BP reporting only suicidal ideation (SI) and BP suicide attempters according to Columbia-Suicide Severity Rating Scale (C-SRSS) criteria. Secondarily, we also investigated whether the C-SRSS Intensity Scale was associated with emergence of suicidal behaviour (SB). METHOD A total of 215 euthymic bipolar out-patients were recruited. Semistructured interviews including the C-SRSS were used to assess sociodemographic and clinical data. Patients were grouped according to C-SRSS criteria: patients who scored ≤1 on the Severity Scale were classified as NS. The remaining patients were grouped into two groups: 'patients with history of SI' and 'patients with history of SI and SB' according to whether they did or did not have a past actual suicide attempt respectively. RESULTS Patients from the three groups differed in illness onset, diagnosis, number of episodes and admissions, family history, comorbidities, rapid cycling and medication, as well as level of education, functioning, impulsivity and temperamental profile. CONCLUSION Our results suggest that increased impulsivity, higher rates of psychiatric admissions and a reported poor controllability of SI significantly increased the risk for suicidal acts among patients presenting SI.

Abstract
OBJECTIVE To identify risk factors associated with suicide of patients with schizophrenia and provide clinical recommendations, which integrate research findings into a consensus based on clinical experience and evidence. METHOD A task force formed of experts and clinicians iteratively developed consensus through serial revisions using the Delphi method. Initial survey items were based on systematic literature review published up to June 2013. RESULTS Various risk factors were reported to be implicated in suicide in schizophrenia. Our findings indicate that suicide risk in schizophrenia is mainly related to affective symptoms, history of a suicide attempt and number of psychiatric admissions. Other risk factors identified are given by younger age, closeness to illness onset, older age at illness onset, male sex, substance abuse and period during or following psychiatric discharge. Integrating the evidence and the experience of the task force members, a consensus was reached on 14 clinical recommendations. CONCLUSION Identification of risk factors for suicide in individuals diagnosed with schizophrenia is imperative to improve clinical management and develop strategies to reduce the incidence of suicide in this population. This study provides the critical overview of available data and clinical recommendations on recognition and management of the above-mentioned risk factors.

Abstract
Bipolar patients (BP) are at high risk of suicide. Causal factors underlying suicidal behavior are still unclear. However, it has been shown that lithium has antisuicidal properties. Genes involved in its putative mechanism of action such as the phosphoinositol and the Wnt/β-catenine pathways could be considered candidates for suicidal behavior (SB). Our aim was to investigate the association of the IMPA1 and 2, INPP1, GSK3α and β genes with suicidal behavior in BP. 199 BP were recruited. Polymorphisms at the IMPA1 (rs915, rs1058401 and rs2268432) and IMPA2 (rs66938, rs1020294, rs1250171 and rs630110), INPP1 (rs3791809, rs4853694 and 909270), GSK3α (rs3745233) and GSK3β (rs334558, rs1732170 and rs11921360) genes were genotyped. All patients were grouped and compared according to the presence or not of history of SB (defined as the presence of at least one previous suicidal attempt). Single SNP analyses showed that suicide attempters had higher frequencies of AA genotype of the rs669838-IMPA2 and GG genotype of the rs4853694-INPP1gene compared to non-attempters. Results also revealed that T-allele carriers of the rs1732170-GSK3β gene and A-allele carriers of the rs11921360-GSK3β gene had a higher risk for attempting suicide. Haplotype analysis showed that attempters had lower frequencies of A:A haplotype (rs4853694:rs909270) at the INPP1 gene. Higher frequencies of the C:A haplotype and lower frequencies of the A:C haplotype at the GSK-3β gene (rs1732170:rs11921360) were also found to be associated to SB in BP. Therefore, our results suggest that genetic variability at IMPA2, INPP1 and GSK3β genes is associated with the emergence of SB in BP.

Impulsivity and functional impairment in bipolar disorder. J Affect Disord 2012; 136:491-7. [PMID: 22129768 DOI: 10.1016/j.jad.2011.10.044] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2011] [Revised: 10/31/2011] [Accepted: 10/31/2011] [Indexed: 10/14/2022]
Abstract
BACKGROUND Impulsivity is substantially higher in bipolar patients (BP) and may be associated with a more severe course of illness, but no studies have so far examined the relationship between impulsivity and functional outcome in BP. Our goal was to investigate the functional impact of trait-impulsivity in BP. METHODS 138 euthymic BP were recruited. All patients were assessed using an interview based on the Structured Clinical Interview for DSM Disorders (SCID). The Functioning Assessment Short Test (FAST) and the Barratt Impulsiveness Scale (BIS-11) were used to assess functional outcome and impulsivity, respectively. Seven multiple linear regressions, with each individual FAST subscale scores and overall FAST score as dependant variables, were conducted in order to evaluate the predictive role of trait-impulsivity on functional outcome. RESULTS After a multiple linear regression model, with the FAST total score as dependent variable, we found that depressive symptoms (β=1.580; p<0.001), number of hospitalizations (β=0.837; p=0.019) and impulsivity (β=0.319; p=0.004) were independently associated with overall functional impairment (F=6.854, df=9, p<0.001, adjusted R2=0.311). LIMITATIONS The cross-sectional design of the study. CONCLUSIONS Our results indicate that impulsivity, as well as depressive symptoms and the number of hospitalizations, is associated with overall functional impairment in BP. The assessment and treatment of impulsivity may be useful in improving functional outcome in BP.

Abstract
OBJECTIVE To describe the impact of tobacco, alcohol and cannabis on metabolic profile and cardiovascular risk in bipolar patients. METHOD Naturalistic, cross-sectional, multicenter Spanish study. Current use of tobacco, alcohol and cannabis was determined based on patient self-reports. Metabolic syndrome was defined using the National Health and Nutrition Examination Survey 1999-2000 and the American Heart Association/National Heart, Lung and Blood Institute criteria, and cardiovascular risk using the Framingham and the Systematic Coronary Risk Evaluation functions. RESULTS Mean age was 46.6 years, 49% were male. Substance use: 51% tobacco, 13% alcohol and 12.5% cannabis. Patients who reported consuming any substance were significantly younger and a higher proportion was male. After controlling for confounding factors, tobacco was a risk factor for coronary heart disease (CHD) (unstandardized linear regression coefficient 3.47, 95% confidence interval 1.85-5.10). CONCLUSION Substance use, mainly tobacco, was common in bipolar patients. Tobacco use negatively impacted CHD risk.

Abstract
INTRODUCTION Our aim was to evaluate treatment safety, tolerability, efficacy and compliance of long-acting injectable risperidone (LAIR) as maintenance treatment in a bipolar and schizoaffective inpatients sample with torpid course due to poor compliance to oral therapy. METHODS 22 inpatients, 14 with a diagnosis of bipolar disorder and 8 with a diagnosis of schizoaffective disorder, were included in this study. They were treated with LAIR, 1 dose every 14 days, and were evaluated for 40 weeks with the Young Mania Rating Scale (YMRS), Hamilton Scale for Depression (HAM-D), UKU-Side Effect Rating Scale and Clinical Global Impression Severity of Illness scales (CGI). RESULTS Average YMRS scores were reduced significantly from 10.5 at baseline interview to 2.5 at week 40 (p < 0.001). HAM-D and UKU scales did not reach a statistically significant reduction. CGI-S scores were reduced from 3.8 at baseline to 1.5 at week 40 (p < 0.001). CONCLUSIONS LAIR could be an effective maintenance therapy for bipolar and schizoaffective patients with poor compliance to oral treatment.

Abstract
BACKGROUND The long-term efficacy of psychological interventions for bipolar disorders has not been tested. AIMS This study assessed the efficacy of group psychoeducation to prevent recurrences and to reduce time spent ill for people with bipolar disorders. METHOD A randomised controlled trial with masked outcome assessment comparing group psychoeducation and non-structured group intervention during 5-year follow-up. One hundred and twenty people with bipolar disorders were included in the study and 99 completed 5-year follow-up. Time to any recurrence, number of recurrences, total number of days spent ill, frequency and length of hospitalisations were the main outcome measures. RESULTS At the 5-year follow-up, time to any recurrence was longer for the psychoeducation group (log rank=9.953, P<0.002). The psychoeducation group had fewer recurrences (3.86 v. 8.37, F=23.6, P<0.0001) of any type and they spent less time acutely ill (154 v. 586 days, F=31.66, P=0.0001). The median number of days of hospitalisation per hospitalised participant was also lower for the psychoeducation group (45 v. 30, F=4.26, P=0.047). CONCLUSIONS Six-month group psychoeducation has long-lasting prophylactic effects in individuals with bipolar disorders. Group psychoeducation is the first psychological intervention showing such a long-term maintained efficacy in people with bipolar disorders.

Abstract
OBJECTIVE Only a few studies have examined specifically the neuropsychological performance of schizoaffective patients. METHOD The sample consisted of 34 euthymic DSM-IV schizoaffective patients, who were compared with 41 euthymic bipolar patients without history of psychotic symptoms and 35 healthy controls. Euthymia was defined by a score of 6 or less at the Young Mania Rating Scale and a score of 8 or less at the Hamilton Depression Rating Scale for at least 6 months. Patients were compared with several clinical, occupational, and neuropsychological variables such as executive function, attention, verbal and visual memory and the two groups were contrasted with 35 healthy controls on cognitive performance. The three groups were compared using mancova after checking the potential role of several co-variables. RESULTS Schizoaffective patients showed greater impairment than controls and bipolar patients, in several domains, including verbal memory, executive function, and attentional measures. Bipolar patients without history of psychosis performed similar to the controls except for verbal fluency. CONCLUSION Schizoaffective disorder carries more neurocognitive impairment than non-psychotic bipolar disorder and more occupational difficulties.

Abstract
BACKGROUND Identifying and modifying burdensome aspects might reduce the level of burden and their negative effects both on caregivers and patients' outcome. Most studies evaluate acutely ill patients, whereas the most relevant problems may be related to subthreshold symptoms and long-term outcome. The aims of the present study were to assess caregiver's subjective burden, to analyse which were the most burdensome aspects for caregivers and to study which variables could explain the caregiver's subjective burden. METHODS Caregivers of 86 euthymic bipolar patients completed the subjective burden subscale from an adapted version of the Social Behaviour Assessment Schedule. RESULTS Caregivers showed a moderate level of subjective burden. The highest levels of distress were reported regarding the patient's behaviour; the most distressing behaviours were hyperactivity, irritability, sadness and withdrawal. Regarding the patient's role performance, the most worrying aspects were those associated with the patient's work or study and social relationships. Regarding adverse effects on others, caregivers were especially distressed by the way the illness had affected their emotional health and their life in general. Poorer social and occupational functioning, an episode in the last 2 years, history of rapid cycling and the caregiver being responsible for medication intake explained a quarter of the variance of the caregiver's subjective burden. LIMITATIONS This was a cross-sectional study focused only on primary caregivers, there was no control group of non-bipolar patients. CONCLUSIONS This study provides relevant data concerning the burden of caregivers of stable bipolar patients, pointing at potential targets for psychosocial interventions.

Abstract
BACKGROUND In clinical practice, bipolar patients complain of cognitive deficits such as attentional or memory disturbances. The main aim of this study was to determine whether subjective cognitive complaints were associated with objective neuropsychological impairments. METHOD Sixty euthymic bipolar patients were assessed through a neuropsychological battery. A structured clinical interview was used to determine subjective cognitive complaints in patients. Thirty healthy controls were also included in the study in order to compare the neuropsychological performance among groups. RESULTS Bipolar patients with a higher number of episodes, especially the number of mixed episodes, longer duration of the illness and the onset of the illness at an earlier age showed more subjective complaints. Furthermore, bipolar patients with subjective complaints showed lower scores in several cognitive measures related to attention, memory and executive function compared with the control group. Nevertheless, patients without complaints also performed less well than controls in some neuropsychological measures. CONCLUSION Bipolar patients who were aware of cognitive deficits were more chronic, had presented more previous episodes, especially mixed type, and their illness had started at an earlier age compared with patients who did not complain about cognitive problems. Moreover, patients with good cognitive insight also had a poorer social and occupational functioning as well as a poorer neuropsychological performance. However, the bipolar group without complaints also obtained lower scores in several tests compared with healthy controls. Cognitive status of bipolar patients should be routinely assessed, regardless of the patients awareness about their cognitive deficits.

Abstract
BACKGROUND Environmental stress has an important role in the course of bipolar disorder. Some findings have shown that family beliefs about the illness could predict family burden, and this burden could influence the outcome of bipolar disorder. To the best of our knowledge, there is scant information about the effects of family intervention on the caregiver's burden in bipolar disorder. The aim of this study was to assess the effects of psychoeducational family intervention on bipolar patients' caregivers, including the assessment of the caregiver's burden. METHODS 45 medicated euthymic bipolar outpatients were randomized into an experimental and a control group. Relatives of patients from the experimental group received 12 psychoeducational, 90-min sessions about bipolar disorder and coping skills. The caregivers' knowledge of bipolar disorder, the relationship subscales of the Family Environment Scale, and the family burden subscales from an adapted version of the Social Behavior Assessment Schedule were assessed for both caregiver groups before and after the intervention. RESULTS Psycho-educated caregivers significantly improved their knowledge of bipolar disorder and reduced both the subjective burden and the caregiver's belief about the link between the objective burden and the patient. No significant differences were found in the objective burden nor in the family relationship subscales. CONCLUSIONS These preliminary results suggest that psychoeducational intervention on caregivers of bipolar patients may improve the caregiver's knowledge of the illness, reduce their distress or subjective burden and alter their beliefs about the link between the disruptions in their life and the patient's illness.

Abstract
OBJECTIVE Cognitive impairment in bipolar disorder may be a stable characteristic of the illness, although discrepancies have emerged with regard to what dysfunctions remain during remission periods. The aim of this study was to ascertain whether euthymic bipolar patients would show impairment in verbal learning and memory and in executive functions compared with healthy controls. Secondly, to establish if there was a relationship between clinical data and neuropsychological performance. METHODS Forty euthymic bipolar patients were compared with 30 healthy controls through a battery of neuropsychological tests assessing estimated premorbid IQ, attention, verbal learning and memory, and frontal executive functioning. The effect of subsyndromal symptomatology was controlled. RESULTS Remitted bipolar patients performed worse than controls in several measures of memory and executive function, after controlling for the effect of subclinical symptomatology, age and premorbid IQ. Verbal memory impairment was related to global assessment of function scores, as well as to a longer duration of illness, a higher number of manic episodes, and prior psychotic symptoms. CONCLUSIONS Results provide evidence of neuropsychological impairment in euthymic bipolar patients, after controlling for the effect of subsyndromal depressive symptoms, suggesting verbal memory and executive dysfunctions. Cognitive impairment seems to be related to a worse clinical course and poor functional outcome.

Abstract
INTRODUCTION Recent studies have suggested that the presence of persistent cognitive dysfunctions in bipolar patients is not restricted to acute episodes, but they persist even during remission states. Nevertheless, there are several methodological pitfalls in most studies, such as unclear remission criteria, diagnostic heterogeneity or small sample sizes. PATIENTS AND METHODS Several domains of cognitive function were examined in 30 depressed bipolar patients [DSM-IV criteria for major depression, Hamilton Depression Scale (HDRS) > or =17] and 30 euthymic bipolar patients (at least 6 months of remission, HDRS < or =8 and Young Mania Rating Scale, YMRS < or =6). Psychosocial functioning was assessed through General Assessment of Functioning. RESULTS The two groups showed a similar pattern of neuropsychological performance. However, the depressed group was significantly impaired on the Controlled Oral Word Association Test, FAS (COWAT), a measure of verbal fluency, compared with the euthymic group. On the other hand, functional outcome in euthymic patients was related to verbal fluency, even after controlling for residual depressive symptoms. CONCLUSIONS Neuropsychological performance was similar in both groups, except for verbal fluency, which was lower in the depressed group. Poor verbal fluency was related to a poor social outcome in euthymic patients. Further research including longitudinal designs aimed at evaluating changes in cognition in these patients is warranted.

Abstract
INTRODUCTION This study analyzes the effectiveness and safety of lamotrigine in the treatment of bipolar II disorder. Patients and methods. Seventeen patients with DSM-IV bipolar II disorder with a history of poor response to lithium or other mood-stabilizers gave their consent to be treated with lamotrigine. Th ey we re followed-up for 6 months and assessed with the Young Mania Scale (YMRS), Hamilton Depression Rating Scale (HDRS-17) and the modified version of the Global Clinic Impresion Scale for Bipolar Disorder ( CG I-BP-M). RESULTS Twelve patients completed the study. Three patients dropped out due to side effects (two because of mild rash, which vanished after treatment was discontinued and one because of vomiting) and two due to lack of efficacy. The mean dose of lamotrigine for patients completing the study was 202.1 64.4 mg/day. There was a significant improvement in HDRS-17 scores (p= 0.004) and the depressive (p=0.002) and overall (p= 0.002) subscales of the CGI-BP-M. CONCLUSIONS This study confirms previous findings concerning the antidepressant profile of lamotrigine and its potential effectiveness in bipolar II disorder.

Abstract
Many neuroimaging investigations report structural differences in subjects with bipolar disorder; however, conflicting results are common in the limited number of available investigations. Thus, the structural correlates of bipolar disorders remain poorly understood. The authors reviewed the early investigations using computed tomography and examined gross structural differences, such as cerebral atrophy, ventricular enlargement, or cerebellar atrophy. Many of these investigations report significant differences in these features compared with controls, whereas others found no such differences. More recent magnetic resonance imaging (MRI) investigations have employed increasingly sophisticated imaging and research methodologies, allowing for the quantitative examination of specific brain regions. Because neuropsychological and functional studies suggest abnormalities in frontal, temporal and subcortical regions, many investigators have focused their MRI neuromorphometric studies on these temporal limbic structures. However, the number of investigations examining each of these regions remains small, and conflicting results continue to be reported. It seems clear that for many brain regions, the structural changes from normal may be subtle, and that the differences in the reported studies may be due to differences in research methodologies between studies and across centers.

Abstract
OBJECTIVES To ascertain the clinical implications of psychiatric comorbidity in the course and outcome of bipolar I patients. METHODS One hundred and twenty-nine bipolar I outpatients in remission [Young Mania Rating Scale (Y-MRS) < 7, Hamilton Depression Rating Scale (HDRS) < 9] were assessed by means of the Structured Clinical Interview for DSM-III-R axis I and axis II (SCID-I and SCID-II) in order to detect all possible psychiatric comorbid diagnoses. The sample was split according to the presence of psychiatric comorbidity and the groups were compared. RESULTS Psychiatric comorbidity was detected in 31% of the sample. A higher number of mixed features, depressive episodes and suicide attempts and a predominance of depressive onset amongst comorbid bipolar patients were the most relevant differences between the two groups. CONCLUSIONS There is an association between depression, suicidality and comorbidity in bipolar I disorder. As comorbidity had a clear relevance in the course and outcome of bipolar illness, this issue should be specifically assessed in clinical practice.

Abstract
BACKGROUND Recent studies have reported that differences in cognitive performance between schizophrenic and bipolar patients seem to be smaller than expected. Patients with schizophrenia have consistently shown frontal executive dysfunctions, but studies regarding executive abilities in bipolar patients are scarce and discrepant. As executive function has been associated with psychosocial functioning in schizophrenia, we wanted to investigate if such a relationship is also present in bipolar disorder and the differences between the two groups. METHODS Executive function was assessed in 49 euthymic (at least 6 months in remission, Hamilton Depression Rating Scale < or = 8 and Young Mania Rating Scale < or = 6) bipolar and in 49 schizophrenic, residual-type (with at least 1 year without acute exacerbation and predominant negative symptomatology) patients, by the Wisconsin Card Sorting Test (WCST), FAS Test (COWAT) and Trail Making Test. Baseline clinical and psychosocial variables were controlled and psychopathology evaluated by means of the Positive and Negative Syndrome Scale (PANSS). RESULTS The two groups showed a similar pattern of cognitive deficits in tests of executive function, except for the number of categories achieved in the WCST, which was significantly lower in the schizophrenic group (F = 7.26; p = 0.009). Functional outcome was predicted by the negative syndrome (PANSSN) and perseverative errors (WCST) in schizophrenic patients, and general psychopathology (PANSSG) was the best predictor of functional outcome in the bipolar group. CONCLUSION Executive function was a good predictor of functional outcome in the schizophrenic group, whereas clinical variables were more predictive of the bipolar one. Patterns of cognitive disturbances in tasks of executive function are similar in both groups but quantitatively more marked in schizophrenia.

Abstract
BACKGROUND Although genetic and biological factors are crucial in the pathophysiology of bipolar disorder, the importance of psychosocial and familial factors in triggering or mitigating relapses warrants the implementation of psychotherapeutic interventions. The authors review and criticize the role of family intervention in bipolar disorder. METHODS The main computerized databases (Medline, Psychological Abstracts, Current Contents) have been searched for the terms 'family intervention', 'family management', 'family therapy', 'psychotherapy', 'psychoeducation' and 'bipolar disorder'. RESULTS Some studies have associated high expressed emotion in relatives and poorer outcome in bipolar disorder. Studies on families of bipolar patients seem to support that family intervention as adjunctive therapy to pharmacological treatment may reduce the number of relapses and hospitalizations, improving familial, occupational and social functioning. However, controlled studies are scarce and most of them have a great number of methodological pitfalls such as small sample size, uncontrolled pharmacological treatment, absence of long follow-up and biased populations, among others. CONCLUSIONS Both bipolar patients and their relatives could benefit from family intervention as adjunctive treatment to pharmacotherapy. Nevertheless, it would be necessary to design further investigations avoiding some of the limitations listed above, and controlling additionally for psychopathology in family members, and the influence of life events. It would be important to distinguish between causes and effects, studying which factors are involved in family attitudes and determining whether the interactive patterns are variable or stable according to the clinical state of the patient. Finally, it would be useful to design viable, effective and measurable interventions for the accurate delimitation of the role of family intervention in the treatment of bipolar disorder.

Abstract
BACKGROUND Since treatment approaches thought to be useful for mania are presumably suitable for hypomania as well, little systematic research has been done on the treatment of hypomanic episodes and their long-term outcome. As systematic trials have shown that the atypical antipsychotic risperidone may be effective and safe in the treatment of acute mania, we decided to conduct an open-label study of its effectiveness and tolerability in hypomania associated with bipolar II. METHODS Forty-four DSM-IV bipolar II patients with Young Mania Rating Scale (YMRS) scores above 7 were included and followed-up for 6 months. Efficacy was measured by means of the YMRS and the Clinical Global Impression for Bipolar Disorder (CGI-BD). Treatment-emergent depression was measured by the Hamilton Depression Rating Scale (HDRS-17), and the Udvalg for Kliniske Undersøgelser (UKU) subscale was used for neurological/extrapyramidal side-effects. RESULTS Thirty-four patients completed the trial. The mean dose of risperidone at endpoint was 2.8 mg/day. Last observation-carried-forward analysis showed significant reduction of YMRS scores from the first week of treatment, which continued until the endpoint (P<0.0001). At 6-month follow-up, 60% of patients were assymptomatic according to the CGI. The 32% who received risperidone in monotherapy seemed to respond equally well. Risperidone, as used in this study, appeared to be most protective against hypomanic than depressive recurrences. Nine patients (12%) had a depressive relapse during 6-month follow-up, one patient (2%) had an hypomanic relapse and another (2%) had both. No patients developed tardive dyskinesia during the duration of the study. Although most patients received risperidone in combination with standard mood-stabilizers, only three patients discontinued risperidone because of other side-effects. LIMITATIONS In the absence of a placebo arm, it is uncertain to what extent the foregoing results could be ascribed to spontaneous remission of bipolar II disorder. CONCLUSIONS Risperidone, either in combination with mood-stabilizers or alone was well-tolerated in bipolar II patients, who presented in a hypomanic state, and appeared efficacious. Further controlled research on the role of atypical antipsychotics in the treatment of less-than-manic forms of bipolar illness is warranted.

Abstract
The aim of this study was to estimate the long-term effectiveness of olanzapine as adjunctive therapy in patients with bipolar disorder who exhibited an inadequate response to mood stabilizers. Twenty-three Research Diagnostic Criteria (RDC) patients with bipolar I and II were assessed by means of the Schedule for Affective Disorders and Schizophrenia and entered if they gave their consent to participate. All of them had experienced frequent relapses, residual subsyndromal symptoms, and inadequate responses to other drugs, such as lithium, valproate, or carbamazepine. While maintaining other drugs, they all received open-label, increasing doses of olanzapine, until achieving clinical response. Other drugs were maintained. The patients were assessed several consecutive times from baseline to the endpoint with the Clinical Global Impressions (CGI) scale for use in bipolar illness. Records of recurrences, hospitalizations, and side effects were also collected. The last-observation-carried-forward analysis showed that there was a significant reduction of CGI scores after the introduction of olanzapine, either in manic symptoms (p = 0.0015), depressive symptoms (p = 0.0063), or global symptoms (p = 0.0003). The most frequent adverse events were somnolence (17%) and weight gain (13%). The mean dose of olanzapine at the end of the 43-week follow-up was 8.1 mg/day. Olanzapine may be a useful medication for the long-term adjunctive treatment of patients with bipolar disorder who exhibit a poor response to mood stabilizers, such as lithium, valproate, or carbamazepine. These results suggest mood-stablizing properties of olanzapine.

Abstract
BACKGROUND The goal of this study was to assess the efficacy and safety of risperidone in bipolar and schizoaffective disorders. METHOD 541 patients entered this open, multicenter, 6-month study. Patients were entered provided that they fulfilled DSM-IV criteria for bipolar disorder or schizoaffective disorder, bipolar type, during a manic, hypomanic, mixed, or depressive episode. Risperidone was added to any previous mood-stabilizing medication that the patients were taking. Efficacy was assessed with the Young Mania Rating Scale (YMRS), the Hamilton Rating Scale for Depression (HAM-D), the Positive and Negative Syndrome Scale (PANSS), and the Clinical Global Impressions scale (CGI). Extrapyramidal symptoms (EPS) were assessed using the UKU Side Effect Rating Scale. RESULTS 430 patients completed the study. Addition of risperidone produced highly significant improvements (p < .0001) on the YMRS and HAM-D at both 6 weeks and 6 months and on the CGI and the scales of the PANSS at both 4 weeks and 6 months. There was a significant reduction in UKU total and subscale scores at 6 months. The mean dose of risperidone was 3.9 mg/day. There was no single case of new-emergent tardive dyskinesia, and there was a very low incidence of exacerbation of mania within the first 6 weeks (2%). Adverse events were few and mostly mild. the most frequent being EPS and weight gain. CONCLUSION This large study provides additional evidence that risperidone is effective and well tolerated when combined with mood stabilizers in the treatment of bipolar disorder and schizoaffective disorder, bipolar type. Previous concerns about exacerbation of manic symptoms were not confirmed.

Abstract
Bipolar patients with a rapid cycling clinical course constitute an interesting sub-group for studies focused on the pathophysiology of the disorder, since several switches can be studied by the investigators in a short period of time. At present, functional neuroimaging techniques, as SPECT and PET, may be used for the neurobiological study of affective disorders. Few longitudinal functional neuroimaging studies assessing the different phases of bipolar disorder have been carried out. However, the published data suggest an asymmetrical temporal lobe dysfunction in depressive and manic phases of bipolar depression. Further studies with larger samples of patients are needed in order to improve our knowledge of the pathophysiology of bipolar disorder.

Abstract
BACKGROUND An adequate therapy for psychotic disorders needs to be effective against mood as well as psychotic symptoms. Analyses of data from clinical trials of risperidone in schizophrenia and small open-label studies in mania suggest that risperidone may have this broad efficacy profile. We present data on a 6-week trial of risperidone for the treatment of schizoaffective disorder that was part of a larger, 6-month surveillance study of patients with affective disorders. METHOD One hundred two patients suffering from schizoaffective disorder (DSM-IV or ICD-10) entered the trial. Inclusion criteria consisted of a current DSM-IV diagnosis of schizoaffective disorder, bipolar type; DSM-IV manic or mixed psychotic episode; and a Young Mania Rating Scale (YMRS) score > 7 for a mixed episode (> 20 for a manic episode). Assessments included the YMRS, the Positive and Negative Syndrome Scale (PANSS), the Hamilton Rating Scale for Depression (HAM-D), the 4-item Clinical Global Impressions (CGI) scale, and the UKU Side Effect Rating Scale subscale for neurologic side effects. For patients entering the study, open-label risperidone therapy was added to their existing regimens of mood-stabilizing treatments. Other antipsychotic drugs were not allowed. RESULTS Ninety-five patients completed the 6-week trial. At week 6, the mean +/- SD dose of risperidone was 4.7+/-2.5 mg/day. The mean scores on the assessment scales at baseline and week 6 (unless otherwise stated) were as follows: YMRS, 22.7 and 4.7, an improvement of 18.0 points (p < .0001); PANSS (at baseline and week 4), 74.1 and 54.2, an improvement of 19.9 points (p < .0001); HAM-D, 14.0 and 7.4, an improvement of 6.6 points (p < .0001); CGI (at baseline and week 4), 2.6 and 1.7, an improvement of 0.9 points (p < .0001). At week 4, most patients had shown improvement in symptom severity, and 9.3% were completely symptom-free. There were no statistically significant differences between baseline and week 4 in the severity of extrapyramidal symptoms as measured by the UKU. Risperidone was well tolerated; side effects were few and generally mild. CONCLUSION The results to date with risperidone indicate that it may have both antipsychotic and mood-stabilizing properties. Despite the limitations of the open-label design, the results indicate that risperidone is a safe and effective therapy in combination with mood-stabilizers for the treatment of patients with manic, hypomanic, and depressive symptoms of mixed episodes in schizoaffective disorder, bipolar type.

Abstract
The clinical case report of a patient who underwent an endoscopic third ventriculostomy for the treatment of a slit ventricle syndrome is presented. After surgery the patient developed a severe complication consisting of an organic personality disorder, characterised by impulsiveness, physical heteroaggressiveness, binge eating, hypersomnia and impairment of memory, and frontal-executive functions.A frontal lobe lesion may explain some of the symptoms presented, such as the uncontrolled impulses, the aggressive behaviour, and even the binge eating. However, a longitudinal neuropsychological evaluation showed a severe deficit in immediate memory and difficulties in planning and consolidation of newly learned information, which may be best related to damage in the frontal basal structures of the brain: the fornix and its connection to the hippocampus and the mamillary bodies. Postoperative MR images confirmed the clinical hypothesis. The emergence of such a severe organic personality disorder and cognitive disturbances as a psychiatric complication of an endoscopic third ventriculostomy has not, it seems, been previously reported elsewhere. Clinicians should take these possible complications into account when recommending this so-called minimally invasive neuroendoscopic procedure.

Abstract
The validity and nosologic status of schizoaffective disorder is still a controversial issue. This study was conducted to analyze the demographic, clinical and prognostic variables that determine the validity of the diagnosis of schizoaffective disorder bipolar type. We analyzed and compared 138 outpatients: 67 with type I bipolar disorder, 34 with schizoaffective disorder bipolar type and 37 with schizophrenia. They were all diagnosed following research diagnostic criteria and assessed according to the Schedule for Affective Disorders and Schizophrenia. Schizoaffective unipolar patients were excluded. The results reaffirmed that, from the standpoints of demographics, clinical features and prognosis, schizoaffective disorders bipolar type can be classified as a phenotypic form at an intermediate point between bipolar I disorder and schizophrenia. These results emphasize the importance of longitudinal follow-up in the diagnosis and assessment of psychotic syndromes. Although cross-sectional symptoms were closer to the schizophrenia spectrum, the course of the illness resembled more that of bipolar patients, resulting in an intermediate outcome.

Abstract
Viability, efficacy against Penicillium expansum on Golden Delicious apples, and storage stability of freeze-dried Candida sake strain CPA-1 were studied. The effect of several protective agents and rehydration media was investigated in the freeze drying of C. sake. Skimmed milk at 10% concentration was a good rehydration medium for all protectants tested. In general, good viability results were obtained when the same solution was used as a protectant and as a rehydration medium. The best survival was obtained when C. sake cells were protected with 10% lactose + 10% skimmed milk and rehydrated with skimmed milk (85% viability). The potential for biocontrol of the best freeze-dried treatments against P. expansum on apples was compared with that of fresh cells. Freeze-dried treatments at 1 x 10(7) CFU/ml reduced the incidence of decay by 45 to 66%. The best biocontrol effect was obtained with cells that had been freeze dried using 10% lactose + 10% skimmed milk as a protectant and 1% peptone as a rehydration medium, with a 66% reduction in rot incidence. However, in all treatments, the efficacy of freeze-dried cells was significantly lower than fresh cells. The stability of freeze-dried samples decreased during storage and was influenced by storage temperature. In the best treatment, storage of C. sake cells for 60 days at 4 degrees C resulte in final concentrations of 2.5 x 10(8) CFU/ml, which was a 10-fold reduction in relation to the initial starting concentration of cells prior to freeze drying.

Abstract
The effects of freezing method, freeze drying process, and the use of protective agents on the viability of the biocontrol yeast Candida sake were studied. Freezing at -20 degrees C was the best method to preserve the viability of C. sake cells after freeze drying using 10% skim milk as a protectant (28.9% survival). Liquid nitrogen freezing caused the highest level of damage to the cells with viability < 10%. Different concentrations of exogenous substances including sugars, polyols, polymers and nitrogen compounds were tested either alone or in combination with skim milk. There was little or no effect when additives were used at 1% concentration. Galactose, raffinose and sodium glutamate at 10% were the best protective agents tested alone but the viability of freeze-dried C. sake cells was always < 20%. Survival of yeast cells was increased from 0.2% to 30-40% by using appropriate protective media containing combinations of skim milk and other protectants such as 5% or 10% lactose or glucose, and 10% fructose or sucrose.

Abstract
The pharmacological treatment of serious mental disorders in the pregnancy, supposes a clinical dare by the possible repercussions on the fetus and the pregnancy: theratogenesis, perinatal syndrome or postnatal sequels in the development. The electroconvulsive therapy (ECT) as much takes implicit a minimum risk for the mother as for the fetus and therefore, it must be located in the highest positions of the therapeutic decision trees. In the present article, are reviewed the consequences of the pharmacological treatment and the ECT in the serious mental disorders during the pregnancy. Is referenced to all of the pharmacological groups and with respect to the ECT: their indications, counterindications, complications and technical procedures advisables. Finally is reviewed the guide line for each syndromical group of psychiatric diseases.

INTRODUCTION The aim of this study was to analyze the effectiveness of gabapentin administration to bipolar patients who had an incomplete response to other mood stabilizers. SUBJECTS AND METHODS Twenty-two RDC bipolar 1 and II patients were assessed by means of the SADS and entered if they gave their consent to participate. All them had suffered from frequent relapses, subsyndromal features (mostly depressive) and incomplete response to other drugs. They all received open-label increasing doses of gabapentin until clinical response. The patients were assessed through the CGI-BP and a specific questionnaire at baseline and at 12 weeks of follow-up. RESULTS Six out of the 22 patients dropped out for various reasons (four because of relapse, one because of side effects and one more because of poor compliance). Eight of the 16 patients that completed the 12-week follow-up showed at least two stages of improvement in the CGI. Using the last observation-carried forward analysis, the improvement was statistically significant for the depression subscale, and apparently related to social functioning, irritability and anxiety. Only one patient dropped out because of intolerance (mild rash). The mean dose of gabapentin was 1,310 mg/day. CONCLUSION Gabapentin may be a useful drug for the add-on treatment of bipolar patients with poor response to other mood stabilizers. Gabapentin may improve depressive residual symptoms such as irritability, social withdrawal or anxiety. These results should be confirmed in randomized clinical trials.

Abstract
The validity and reliability of the diagnosis of bipolar II disorder has been questioned by means of comorbidity with nonaffective disorders, including substance abuse, personality disorders, and anxiety disorders. This study examined the comorbid diagnosis of a sample of bipolar II patients, comparing patients with comorbidity and those with "pure" bipolar II disorder. Forty Research Diagnostic Criteria (RDC) bipolar II patients were assessed by means of the Schedule for Affective Disorders and Schizophrenia, Lifetime Version (SADS-L) and Structured Clinical Interview for DSM-III-R axis I (SCID-II) for personality disorders. Patients fulfilling RDC criteria for any psychiatric disorder (except personality disorders) or DSM-IV criteria for any personality disorder were compared with patients without comorbidity. For practical reasons, cyclothymia was not considered as a comorbid diagnosis. Half of the sample had lifetime comorbidity with other psychiatric disorders, mainly personality disorders (33%), substance abuse or dependence (21%), and anxiety disorders (8%). However, only the rates of suicidal ideation (74% v 24%, chi square [chi2] = 9.03, P = .003) and suicide attempts (45% v 5%, chi2 = 8.53, P = .003) were significantly different between patients with and without comorbidity. In summary, although the rates of comorbidity are relatively high in bipolar II disorder, most clinical and course variables are strikingly similar in patients with and without comorbidity except for suicidal behavior, suggesting that comorbidity does not reduce the validity of the diagnosis of bipolar II disorder.

Abstract
BACKGROUND Noncompliance with medication is a very common feature among bipolar patients. Rates of poor compliance may reach 64% for bipolar disorders, and noncompliance is the most frequent cause of recurrence. Knowledge of the clinical factors associated with noncompliance would enhance clinical management and the design of strategies to achieve a better outcome for bipolar patients. Although most patients withdraw from medication during maintenance treatment, compliance studies in euthymic bipolar samples are scarce. METHOD Compliance treatment and its clinical correlates were assessed at the end of 2-year follow-up in 200 patients meeting Research Diagnostic Criteria for bipolar I or bipolar II disorder by means of compliance-focused interviews, measurements of plasma concentrations of mood stabilizers, and 2 structured interviews: the Schedule for Affective Disorders and Schizophrenia and the Structured Clinical Interview for DSM-III-R Axis II disorders. Well-compliant patients and poorly compliant patients were compared with respect to several clinical and treatment variables. RESULTS The rate of mildly and poorly compliant patients was close to 40%. Comorbidity with personality disorders was strongly associated with poor compliance. Poorly compliant patients had a higher number of previous hospitalizations, but reported fewer previous episodes. The type of treatment was not associated with compliance. CONCLUSION Clinical factors, especially comorbidity with personality disorders, are more relevant for treatment compliance than other issues such as the nature of pharmacologic treatment. Compliant patients may have a better outcome in terms of number of hospitalizations, but not necessarily with respect to the number of episodes. Bipolar patients, especially those with personality disorders, should be monitored for treatment compliance.

[Long-term effects of the treatment with risperidone versus conventional neuroleptics on the neuropsychological performance of euthymic bipolar patients].

Abstract
INTRODUCTION An increasing number of studies point to the persistence of cognitive deficits in a subpopulation of euthymic bipolar disorders. Atypical antipsychotics represent an interesting alternative treatment compared with conventional neuroleptics, because the former might cause lesser affection of cognitive functions. The objective of this study was to establish, for euthymic bipolar patients who need long-term antipsychotic treatment, the neuropsychological and outcome (occupational functioning) differences between the patients treated with risperidone and the patients treated with conventional neuroleptics. SUBJECTS AND METHOD A sample of twenty RDC bipolar I and II patients were assessed by means of the SADS. All of them were euthymic (HDRS < 8; YMRS < 6) for at least 6 months and treated with antipsychotics. Patients who received risperidone (N = 11) were compared with patients who received conventional neuroleptics (N = 9) with respect to their neuropsychological profile. RESULTS There were significant differences in Trail Making Test-part B (p = 0.038) and in occupational outcome (p = 0.024), favouring patients who were treated with risperidone. There were no significant differences in other neuropsychological tests, but the patients treated with risperidone tended to score higher in most measures of cognitive performance. CONCLUSIONS Among bipolar patients who need long-term antipsychotic treatment for preventing relapses, patients who receive risperidone show more cognitive flexibility and better occupational adaptation than patients treated with conventional neuroleptics.

Abstract
In this review we comment the results of functional neuroimaging works of emotions on normal population and some parallelisms with the emotional changes of bipolar disorder correlated with their functional neuroimaging. Initially we refer the emotional ontogenetical development of human brain based on regional cerebral sanguineous flow evolution (FSC). Secondly we describe the differences of FSC between the externally generated emotions versus internally; between positive versus negative emotions and the correlation between FSC and some facial expressions. When FSC of bipolar disorder is compared with normal emotions on general population, we observe that temporal cortex, the prefrontal medial and insular anterior cortex, change their perfusion with the switch or the change of emotional expression. It is possible to determine if the findings obtained in samples of healthy subjects and bipolar patients converge in a dimensional model, or if on the contrary they support the categorical hypotheses, moving the emotional aspects to a second term on bipolar disorder.

Abstract
Although cognitive dysfunctions in psychosis have classically been associated with schizophrenia, there is clinical evidence that some bipolar patients show cognitive disturbances either during acute phases or in remission periods. The authors critically review the data on cognitive impairment in bipolar disorder. The main computerized databases (Medline, Psychological Abstracts, Current Contents) have been consulted crossing the terms 'cognitive deficits', 'neuropsychology', 'intellectual impairment', 'mania', 'depression' and 'bipolar disorder'. Changes in the fluency of thought and speech, learning and memory impairment, and disturbances in associational patterns and attentional processes are as fundamental to depression and mania as are changes in mood and behavior. Moreover, a significant number of bipolar patients show persistent cognitive deficits during remission from affective symptoms. However, there are several methodological pitfalls in most studies such as unclear remission criteria, diagnostic heterogeneity, small sample sizes, absence of longitudinal assessment, practice effect and poor control of the influence of pharmacological treatment. Most studies point at the presence of diffuse cognitive dysfunction during the acute phases of bipolar illness. Most of these deficits seem to remit during periods of euthymia, but some of them may persist in approximately one third of bipolar patients. Methodological limitations warrant further research in order to clear up the relationship between neuropsychological functioning and clinical, demographic and treatment variables in bipolar disorder.

Abstract
BACKGROUND Dysregulation of corticotropin (ACTH) and cortisol response after corticotropin-releasing hormone (CRH) stimulation has been reported in bipolar patients. Most findings involve the pathophysiology of the depressive phase of the illness and its prediction. However, the possible predictive value of the CRH challenge test with respect to manic episodes remains unknown. METHODS The ACTH and free cortisol response to the injection of 100 microg of synthetic human CRH and plasma cortisol-binding globulin levels were measured in 42 lithium-treated patients suffering from Research Diagnostic Criteria bipolar I disorder in remission, and 21 age- and sex-matched normal controls. A 1-year follow-up was conducted to assess any possible relationship between outcome and the hormonal response. RESULTS Bipolar patients showed higher baseline and peak ACTH concentrations than control subjects. A higher area under ACTH concentration curve after CRH stimulation predicted manic/hypomanic relapse within 6 months by multiple regression analysis. CONCLUSION Bipolar patients in remission show mild abnormalities in ACTH levels before and after CRH stimulation. CRH challenge may be a potentially good predictor of manic or hypomanic relapse in remitted bipolar patients.

Abstract
The pharmacological treatment of serious mental disorders in the pregnancy, supposes a clinical dare by the possible repercussions on the fetus and the pregnancy: theratogenesis, perinatal syndrome or postnative sequels in the development. The electroconvulsive therapy (ECT) as much takes implicit a minimum risk for the mother as for the fetus and therefore, it must be located in the highest positions of the therapeutic decision trees. In the present article, are reviewed the consequences of the pharmacological treatment and the ECT in the serious mental disorders during the pregnancy. Is referenced to all of the pharmacological groups and with respect to the ECT: their indications, counterindications, complications and technical procedures advisables. Finally is reviewed the guide line for each syndromical group of psychiatric diseases.
