- Gray matter volumes in patients with bipolar disorder and their first-degree relatives(2015) NERY, Fabiano G.; GIGANTE, Alexandre Duarte; AMARAL, Jose A.; FERNANDES, Francy B. F.; BERUTTI, Mariangeles; ALMEIDA, Karla M.; CARNEIROC, Camila de Godoi; DURAN, Fabio Luis Souza; OTADUY, Maria G.; LEITE, Claudia Costa; BUSATTO, Geraldo; LAFER, BenyBipolar disorder (BD) is highly heritable. First-degree relatives of BD patient have an increased risk to develop the disease. We investigated abnormalities in gray matter (GM) volumes in healthy first-degree relatives of BD patients to identify possible brain structural endophenotypes for the disorder. 3D T1-weighted magnetic resonance images were obtained from 25 DSM-IV BD type I patients, 23 unaffected relatives, and 27 healthy controls (HC). A voxel-based morphometry protocol was used to compare differences in GM volumes between groups. BD patients presented reduced GM volumes bilaterally in the thalamus compared with HC. Relatives presented no global or regional GM differences compared with HC. Our negative results do not support the role of GM volume abnormalities as endophenotypes for BD. Thalamic volume abnormalities may be associated the pathophysiology of the disease.
