The authors tested the associations of family history and personal history of depression with mood disorders among patients with Alzheimer's disease (AD; N=161). Considered individually, a positive family history and a positive personal history each conferred increased risk for depression in AD. Conjointly, neither family nor personal history accounted for a substantial amount of the variance in syndromal depression after the onset of AD. Most depressed AD patients in this sample did not have a positive family history or a previous episode of depression. Our understanding of the etiology and course of depression and dementia may be augmented with further neuropsychological and brain-imaging studies of the neuropathological substrates shared by these illnesses.
