Dementia: A Clinical and EEG Study of 274 Patients Over the Age of 60

Abstract

The purpose of the investigation was the assessment of dementia from a clinical and EEG viewpoint in patients aged 60 and over, resident in a mental hospital containing a high proportion of elderly long-stay persons. All patients of suitable age were examined irrespective of diagnosis, provided that this was technically possible and, if alive, they were re-examined three years later, in the hope that a longitudinal study would give additional information as suggested by Rosemanet al.(1952) and Sheridanet al.(1955).
