[Influence of lifestyle on neurodegenerative diseases]

Abstract

Lifestyle factors in midlife have an important influence on the risk of developing a neurodegenerative disease during later life. Data on lifestyle factors exist for Alzheimer's disease and Parkinson's disease. Continuous physical and cognitive activity, a balanced or Mediterranean diet with a high proportion of unsaturated fatty acids, the pharmacological treatment of arterial hypertension, sufficient and unfragmented sleep and possibly treatment with lipophilic statins reduce the risk of developing dementia later in life. Several studies in recent years have provided evidence that during the last decades the age-adjusted incidence of dementia has decreased. This is probably due to a healthier lifestyle and the treatment of risk factors. Continuous physical activity also decreases the likelihood of developing Parkinson's disease. Whether lifestyle factors also have an influence on the course and the progression of Alzheimer's and Parkinson's diseases in the symptomatic stages is unknown.
