Bipolar disorder (BD) is characterized by an alternated occurrence between acute mania episodes and depression or remission moments. The objective of this study is to analyze the information processing changes in BP (Bipolar Patients) (euthymia, depression and mania) during the oddball paradigm, focusing on the P300 component, an electric potential of the(More)
BACKGROUND There is increasing evidence that neurocognitive dysfunction is associated with the different states in Bipolar Disorder. Gamma coherence is strongly related to cognitive processes and cortico-cortical communication. This paper aims at shedding light on the relationship between cortical gamma coherence within bipolar patients and a control group(More)
The present study analyzed absolute theta power (ATP) in brain areas involved with attention in the three phase of BD while the patients performing a saccadic attention task. We hypothesized that patients in depression and mania states show a higher ATP compared to euthymic patients, since a higher ATP is indicative of attention deficit. We analyzed the(More)
OBJECTIVE To evaluate whether having general insight into bipolar disorder and its symptoms is affected by the mood state of the patient, using the Insight Scale for Affective Disorders, a hetero-application scale for people with mood disorders. METHODS Ninety-five patients with bipolar disorder were evaluated and divided into different groups according(More)
In bipolar disorder, levels of insight vary as a function of the mood state and appear to influence pharmacology compliance, quality of life, the presence of suicidal ideations, and aggressive behavior. To establish a comparison among different mood states in bipolar with regard to level of insight. Forty-eight patients were evaluated in different affective(More)
INTRODUCTION Prospective studies have shown that the course of bipolar disorder (BD) is characterized by the persistence of symptoms, predominantly depression, along most of the time. However, to our knowledge, no studies in Latin America have investigated it. OBJECTIVES To replicate international studies using a Brazilian sample to prospectively analyze(More)
Some studies have indicated that the capacity of self-assessment of affective state is more compromised during mania than during depression. In the present study, we investigated whether the reliability of self-assessment in bipolar disorder varies as a function of actual affective state (i.e., euthymia, mania, or depression). Sixty-five patients with a(More)
BACKGROUND Some studies indicate that mood self-assessment is more severely impaired in patients with bipolar disorder in a manic episode than in depression. OBJECTIVES To investigate variations in mood self-assessment in relation to current affective state in a group of individuals with bipolar disorder. METHODS A total of 165 patients with a diagnosis(More)
