determining the prevalence of attention deficit hyperactivity disorder (adhd) in patients with bipolar disorder type i (bid) within their remission phase

background: there have been several studies conducted on the relationship between bipolar mood disorder and attention deficit hyperactivity disorder ( adhd) during the recent years, and in most of them the rate of this association had been estimated as 22-90% and had been reported as noticeable. the goal of this study is to determine the prevalence of adhd in patients with bipolar mood disorder type i (bid). materials and methods: in this cross-sectional study, 152 patients with bid that were referred to psychiatric clinic of tehran psychiatric institute for a better observation and treatment were included. two questionnaires, wender’s for childhood adhd and conner’s’ for adulthood adhd were filled by the patients. results: 102 patients (67%) were males and 50 were females. the average age of patients at the time of our study (with the minimum of 17 and maximum of 76) was 33.5±10.9. the prevalence of adhd in our patients was 11.8%. 46 people (30.9%) had a history of childhood adhd. 21 persons had adult adhd from whom only 3 ones mentioned a history of childhood adhd (which means 18 people of our adulthood adhd had no history of childhood adhd). conclusion: since some treatments lead to improvement of adhd and worsening of bid, investigations on their correlations and their alternative treatments seemed to be necessary. this study showed a significant correlation between adhd and bid, which was similar to the results of other studies in this field.
