Study of the clinical profile of older patients with bipolar disorder in a tertiary care center in the Midwest of Brazil

Abstract

Objective: This study aimed to describe the clinical and psychiatric characteristics of older outpatients with bipolar disorder (BD), including psychiatric history (age of onset of symptoms,length of time with the illness, and number of psychiatric hospitalizations), mood state, and cognitive function. Methods: This was a cross-sectional study where clinical and demographic data were obtained by a psychiatric interview with each patient and family members as well as by a review of medical records. The sample consisted of 20 individuals aged 60 years or older with a diagnosis of BD type I according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. Descriptive data analysis was performed, with categorical variables expressed as absolute and relative frequencies. Results: No patient had manic or depressive symptoms at the time of the evaluation; 15(75.0%) had an early onset while 5 (25.0%) had a late onset of the disease. Nine patients(45.0%) showed no cognitive decline whereas 11 (55.0%) showed mild cognitive impairment. Conclusions: This study presents an understudied group of patients with BD. Considering the personal impact and burden on the health system related to this psychiatric condition, it is recommended that further studies be conducted in this area to better evaluate this growing population.
