Abstract
BACKGROUND: Basal ganglia (BG) enlargement has been found in studies of adults with bipolar disorder (BPD), while the few studies of BPD youths have had mixed findings. The BG (caudate, putamen, globus pallidus, nucleus accumbens) is interconnected with limbic and prefrontal cortical structures and therefore may be implicated in BPD. METHODS: Sixty-eight youths (46 with BPD, 22 healthy controls) received neurological and psychiatric assessment, semi-structured interviews, and neuropsychological testing, followed by anatomic magnetic resonance imaging on a 1.5 Tesla scanner. After image segmentation, log BG volumes and asymmetry indices were analyzed using MANOVAs controlling for the effects of cerebral volume, age, sex, and diagnosis. These omnibus tests were followed by univariate linear regression models of each BG structure.
