The purpose of this study is to look at certain structural changes in the brain in people with bipolar disorder or those with a history of Bipolar disorder.
Individuals with bipolar disorder or those with a history of bipolar disorder may have certain structural changes in their brain. The purpose of this study is to look at those changes, as well as the assessment of risk factors for bipolar disorders, involving both social and psychological aspects of behavior, age, education, marital relations, nutrition, physical activity, etc., compared with persons not having bipolar disorder. These changes in the brain will be measured by Magnetic Resonance Imaging (MRI).

Boyko DWM Hyperintensity Value >2 in Subjects Who Received Acute Treatment for Mania
Subject with acute mania were treated for 3 weeks with STEP-BD protocol using valproic acid as the primary intervention. Subject MRI's were evaluated for the presence of deep white matter hyperintensities (DWM) (\>2 on the the Boyko Classification). Boyko lesion classification system assesses DWM hyperintensities as follows: 0 = absent, 1 = punctate, 2 = rounded \<5 mm, 3 = irregular \>5 mm, 4 = confluent lesions.
Time frame: 3 weeks
Boyko DWM Hyperintensity Value >2 in Subjects Who Received Continuation Treatment
Subject were evaluated for relapse of their mood disorder and for the presence of DWM Hyperintensities (\>2 on the the Boyko Classification. Boyko lesion classification system assesses DWM hyperintensities as follows: 0 = absent, 1 = punctate, 2 = rounded \<5 mm, 3 = irregular \>5 mm, 4 = confluent lesions. Subjects were also assessed for relapse, as defined by the Montgomery-Asberg Depression Rating Scale (MADRS)and the Young Mania Rating Scale (YMRS). Relapse was defined by protocol as either a MADRS scale \>15 or a YMRS scale \>15.
Time frame: 12 months
Boyko Subcortical (SC) Hyperintensity Value >2 in Subjects Who Received Continuation Treatment
Subject were evaluated for relapse of their mood disorder and for the presence of subcortical (SC) Hyperintensities (\>2 on the the Boyko Classification). Boyko lesion classification system assesses SC hyperintensities as follows: 0 = absent, 1 = punctate, 2 = rounded \<5 mm, 3 = irregular \>5 mm, 4 = confluent lesions. Subjects were also assessed for relapse, as defined by the Montgomery-Asberg Depression Rating Scale (MADRS)and the Young Mania Rating Scale (YMRS).
Time frame: up to 12 months
fa LOFC in Subjects Who Received Continuation Treatment
As an exploratory analysis, subject MRI's were also evaluated using diffusion tensor imaging (DTI) for differences in fractional anisoptery (fa) in the Left Orbitofrontal area (LOFC). FA is a scalar value between zero and one hundred that describes the degree of anisotropy of a diffusion process. A value of zero means that the diffusion is isotropic (unrestricted in all directions). A value of one hundred means that diffusion occurs only along one axis and is fully restricted along all other directions.
