To determine the time to remission and recurrence in patients treated for acute mania and the predictive factors associated with these outcomes.


This observational study, conducted in Turkey from April 2003 to January 2005, included patients with a DSM-IV diagnosis of bipolar I disorder, acute manic or mixed episode who were eligible to have an oral medication initiated or changed for the treatment of the episode. The patients were followed-up for 12 months.


A total of 584 patients (mean ± SD age = 33.9 ± 11.2, 55.2% outpatients) were enrolled in 53 centers. Eighty-five percent of patients had a manic episode at baseline, with a mean ± SD duration of 21.6 ± 24.4 days. The baseline mean ± SD Clinical Global Impressions scale for use in bipolar disorder and Young Mania Rating Scale (YMRS) scores were 4.9 ± 0.9 (median = 5.0) and 33.2 ± 9.3 (median = 33), respectively. 539 patients achieved remission and, of those, 141 patients had recurrence. One-year remission and recurrence rates were 99.0% and 35.7%, respectively. Mean ± SD times to remission and recurrence in descriptive statistics were 80.9 ± 73.8 (median = 50) and 159.0 ± 95.5 (median = 156) days, respectively. In Cox regression analysis, psychiatric comorbidities (p = .048), a higher YMRS score (p < .001), and a higher number of previous depressive episodes (p = .009) were statistically significant predictors of a longer time to reach remission. Index episodes of longer duration (p = .033) and mixed type (p = 0.49) were significant predictors of a shorter time to recurrence. Confounding factors like concomitant treatment, comorbidities, and lack of blinding and randomization were other limitations.


Predictors for a longer time to remission were psychiatric comorbidities, a higher YMRS score, and a higher number of previous depressive episodes. Predictors for a shorter time to recurrence were episodes of longer duration and mixed type.
