Neuropsychological deficits among older depressed patients with predominantly psychological or vegetative symptoms.
Depressed outpatients having primarily psychological or vegetative symptoms, as defined by the factor analytically developed Hamilton Depression Scale superfactors described by Rhoades and Overall (1983), were compared with similarly aged normal controls on a comprehensive neuropsychological battery. The vegetative group evidenced poorer performance than controls on several measures associated with right hemisphere functioning and on a task associated with executive functioning. In contrast, the psychological group did not significantly differ from controls on any measure, and had significantly better performance than the vegetative group on several tasks. These findings suggest that neuropsychological deficits associated with depression may be limited to those patients with primarily vegetative symptoms.
