Abstract

Objectives: To assess and compare demographic and diagnostic characteristics of inpatients with mood disorders in Iran. Materials and Methods: We collected the demographic, clinical, and treatment characteristics of patients, who were hospitalized during five years from April 2006 to March 2010, in Iran hospital of psychiatry, a residency training center to evaluate the general clinical picture of the disorder. Results: Overall, 95.3 of subjects had a diagnosis of bipolar I disorder (BID), 2.5 were diagnosed as bipolar II disorder (BIID) and 1.3 and 0.9 met the criteria for major depressive disorder (MDD) and bipolar not otherwise specified (NOS), respectively. Compared to patients withMDDand BIID, the onset of BID was at an earlier age (32.2 ± 1, 34.8 ± 1.5 and 29.9 ± 1.9 years old, respectively, P < 0.001). In addition, a number of admissions, mean duration of each admission and number of treatments with electro-convulsive therapy (ECT) were significantly higher in patients with BID. Conclusions: Bipolar I disorder was the most common diagnosis for inpatients with mood disorders and a more severe course in BID may indicate more severe impairments that would result in more severe disabilities. © 2016, Mazandaran University of Medical Sciences
