The Well, the Mentally Ill, the Old and the Old Old: a Community Survey of Elderly Persons in London

Abstract
A random sample of 396 elderly people living at home in the Greater London community was interviewed by psychiatrists using standardised assessments. The sample was divided into the old (aged 65–74) and the old/old (aged 75 and over). The proportions with mental illness were identified and excluded from the sample in order to allow comparison of mentally normal elderly persons between these age groups. Surprisingly few differences emerge. No difference in educational attainment appeared, but there was a small diminution (P < 0.01) in intellectual function to clinical testing, in the old/old. Leisure interests were maintained and high level life satisfaction, health and happiness were claimed.
