Mental Health in the Elderly

Abstract

Increase in life expectancy, together with a reduction in fertility, is causing unprecedented changes in the age structure of the world population. The importance of age-related diseases, mental illness among them, is increasing – in the developed countries, some 25% of the elderly population suffer from mental disorder. This review delineates the factors – social, behavioural, physical, economic, genetic – contributing to severe forms of mental disorder, particularly Alzheimer's disease, cerebrovascular dementia and depression, and discusses recent technological advances. The interaction of physical and mental health is also discussed.
