[Physical Activity and Mental Health in the Elderly].

Physical Activity and Mental Health in the Elderly The aging process is closely linked to physiological changes. These physiological changes may lead to an increased vulnerability for developing somatic and mental disorders. Reduced physical activity/sedentary behaviour can enhance this process. In contrast, physical training and sports counteract this process, in particular in the elderly, who may thus gain or maintain a younger biological age. Physical fitness is associated with better mental health in the elderly. Sports and physical activity over the course of life have shown to be of preventive value concerning the development of depression and dementia in old age. Also late-life depression and cognitive impairment (MCI, mild cognitive impairment) can be improved by regular, continuous physical exercise. Some data furthermore suggest that even patients with dementia benefit from physical exercise, especially on behalf of the behavioural and psychic symptoms of dementia (BPSD).
