Evidence of neurobiologic differences between bipolar subtypes

December 3, 2012

Taiwanese researchers have found differences in fronto-limbic metabolism and executive function between patients with bipolar disorder (BD) I and II.

In the study, 34 right-handed patients with remitted BD (17 each with BD I and BD II) undergoing treatment and 17 healthy individuals were assessed using fluorodeoxyglucose positron emission tomography (PET) and neuropsychological tests of attention, memory, and executive function.
