Division of Psychiatric Neuroimaging, Johns Hopkins University, Baltimore, Catonsville, Maryland
Biol Psychiatry 57:633-9. 2005..One possibility is that volumetric abnormalities are determined by disease subtype. Prior evidence suggests that psychotic (PBP) and nonpsychotic (NPBP) forms of BP are two subtypes that might differ in pathophysiology...
