Dementia is the result of a set of underlying pathological processes, some which are preventable. Genetic factors, age and family history are disclosed as the major non-modified risk factors while modified risk factors range from alcoholism, hypertension, and diabetes mellitus to depression. All this contribute to the development of Alzheimer’s and plausible preventive solutions are therefore obtained from these problems.
In addition, genetic vulnerability is seen to modify most of the risks associated with Alzheimer’s. Although there is insufficient evidence to cement primary prevention recommendations on dementia, physicians may advocate taking actions such as lowering cholesterol, blood pressure and homocysteine levels and controlling diabetes.
Three components of lifestyle, that is, social, mental and physical are associated with a magnificent reduction in the risk of dementia, and Alzheimer’s disease. Population based longitudinal studies have supported the hypothesis that social, cognitive and physical activity are inversely associated with the risk of dementia, Alzheimer’s disease and cognitive impairment. Physical exercise has been thought to enhance brain neurtotrophic factors and modify apoptosis. Dementia is lowered by preserving muscles mass as well as preventing falls and consequent head trauma (Kreil et. al., 2010,pp.18-19).
