Physical exercise for Alzheimer's disease prevention
Exercise has been associated with a reduced incidence of Alzheimer's disease. There are a number of theories that attempt to explain this association, but so far it is not scientifically clear how or why physical activity plays a role in reducing the chances of getting Alzheimer's disease. Studies have not pointed to a particular fitness method that is more effective than other fitness methods for Alzheimer's disease prevention.
The current recommendation is to maintain regular and consistent physical activity. Activities such as walking, swimming, biking, jogging and moderate athletic activity seem to provide the same benefit in Alzheimer's prevention as more physically demanding competitive sports. However, exercise that is associated with head injuries has been found to contribute to psychosocial problems and may worsen Alzheimer’s disease.
Risk factor modification for Alzheimer's disease prevention
Medical management of the known risk factors for Alzheimer's disease is the preventative approach with the strongest evidence. Medical conditions such as hypertension, diabetes, heart disease and stroke are considered contributors to the development of Alzheimer's disease. Prevention of these conditions requires scheduled medical examinations with a doctor who may order screening tests if there is concern that needs deeper investigation. Often, prescription medication may be necessary to treat underlying medical conditions and to prevent them from worsening.
