This hypothesis was evaluated by comparing the frequency and severity of depressive symptomatology in three diagnostic conditions: Alzheimer's disease (AD) (n=30) I subcortical vascular disease (SVD) (n=30), and Parkinson's disease (PD) (n=30). While AD and PD are prototypical exemplars of cortical and subcortical dementia syndromes respectively, SVD provides a test of the generality of the hypothesis as a subcortical neurodegenerative condition whose pathology is not confined to a single subcortical nucleus.

Assessment methods included the Hamilton Rating Scale for depression derived from interview with the patient's primary caregiver (HRSCG) and from interview with the patient (HRSEX), and the self-report Geriatric Depression Scale. The severity of current depressive symptomatology across the three neurodegenerative disorders followed a consistent pattern across each method of assessment.
