Anorexia nervosa in old age

Anorexia Nervosa (AN) occurs in all age groups from adolescence to old age. We describe six cases which presented to an old age psychiatry service over a ten-year period. These illustrate how the effects of aging modify the clinical picture but do not alter the fundamental problem of self-inflicted low body weight. A reduction in agism and increased reporting of the condition in old age may well help in understanding the condition as a whole.
