ABSTRACT
ABSTRACT Background: Patients with Bipolar Disorder (BD) have the highest lifetime risk for suicidal behavior (SB) compared to other psychiatric disorders. Neuroimaging research provides evidence of some structural and functional abnormalities in the brain of BD suicide attempters (SA), but interpretation of these findings may represent a number of features. Objective: The purpose of this study was to evaluate the volume of the prefrontal cortex in euthymic BD type I outpatients, with and without history of SA. Methods: 36 euthymic BD I outpatients (18 with and 18 without suicide attempt history) were underwent structural MRI and total and regional gray matter volumes were assessed and compared with 22 healthy controls (HC). Results: We did not found any differences in all areas between suicidal and non-suicidal BD I patients and BD patients as a group compared to HC as well. Discussion: our findings suggest that can be a different subgroups of patients in relation to prefrontal cortex volumes according to some clinical and socio-demographic caractheristics, such as number of previous episodes and continuous use of medical psychotropic drugs that may induce neuroplasticity phenomena, which restore cerebral volume and possibly can lead to long-term euthymia state.
ABSTRACT
Objective: To identify, by means of a systematic review, the frequency with which comorbid personality disorders (PDs) have been assessed in studies of euthymic bipolar patients. Methods: PubMed, ciELO and PsychINFO databases were searched for eligible articles published between 1997 and 2013. After screening 1,249 empirical papers, two independent reviewers identified three articles evaluating the frequency of PDs in patients with bipolar disorders assessed in a state of euthymia. Results: The total sample comprised 376 euthymic bipolar patients, of whom 155 (41.2%) had at least one comorbid PD. Among them, we found 87 (23.1%) in cluster B, 55 (14.6%) in cluster C, and 25 (6.6%) in cluster A. The frequencies of PD subtypes were: borderline, 38 (10.1%); histrionic, 29 (7.7%); obsessive-compulsive, 28 (7.4%); dependent, 19 (5%); narcissistic, 17 (4.5%); schizoid, schizotypal, and avoidant, 11 patients each (2.95%); paranoid, five (1.3%); and antisocial, three (0.79%). Conclusion: The frequency of comorbid PD was high across the spectrum of euthymic bipolar patients. In this population, the most common PDs were those in cluster B, and the most frequent PD subtype was borderline, followed by histrionic and obsessive-compulsive. .

OBJETIVO: Avaliar a presença e o grau de consciência da doença na doença de Alzheimer (DA) em estágio leve e moderado. MÉTODO: Pacientes com DA leve/moderada (n=42) avaliados em corte transversal através da Escala de Avaliação do Impacto Psicossocial do Diagnóstico de Demência (APSID), Mini-Exame do Estado Mental (MEEM) e Estadiamento Clínico das Demências (CDR). RESULTADOS: No estágio leve (n=18), 66,7 por cento dos pacientes perceberam os sintomas cognitivos e os prejuízos causados na vida cotidiana. No estágio moderado (n=24), 20,8 por cento tinham consciência da doença preservada; em 45,8 por cento observou-se somente a noção sobre a presença de sintomas cognitivos; ausência total de consciência da doença foi encontrada em 33,3 por cento. CONCLUSÃO: Os dados encontrados indicam a associação entre consciência e evolução clínica da doença. Pacientes com CDR 1 reconhecem melhor os sintomas cognitivos e dificuldades de atividade de vida diária. A maioria dos pacientes com CDR 2 reconhece seus sintomas, mas não percebe a gravidade e as conseqüências nas atividades de vida diária.

Relatos de casos sobre o uso de olanzapina na doença de Huntington (DH) usaram doses variando de 10-30 mg. Este é um relato de caso de DH avaliado pela Unified Huntington Rating Scale no início e quatro meses depois com uma dose baixa de olanzapina. A paciente melhorou dos sintomas motores, psiquiátricos e nas atividades de vida diária após os quatro meses de tratamento. A resposta a baixas doses de olanzapina na DH pode ser um indicador de eficácia em casos similares. Mais estudos controlados randomizados podem avaliar apropriadamente esses achados.
