This study is the first to use reporting sources close to the subject to examine mood and personality changes in patients with left- (LH) and right-hemisphere (RH) stroke lesions. Ss (29 with RH lesions, 27 with LH lesions, and 14 with bilateral lesions) together with their significant others, were assessed approximately 2 weeks poststroke. Depression was one of the major types of emotional change regardless of lesion site. Other emotional concomitants included increased indifference, inappropriate behavior, and pragnosia (defective social communication style). A significant three-way interaction indicated that, during the acute stroke phase, the syndrome of depression and other mood and personality changes in LH patients significantly differentiated them from their RH counterparts. Specific patterns of changes from premorbid to poststroke status are discussed in terms of their theoretical, clinical, and research implications.
