Prevention of Alzheimer’s Disease: Theories and Approaches

Alzheimer’s is the widespread age-related disease that causes memory loss and problems with thinking and behavior. It affects older individuals and accounts for the majority of dementia cases worldwide (Alzheimer’s Association, n.d.). Researchers point that although this disease typically affects people in their advanced age, it is not a normal part of the aging process because it can develop even in people under the age of 65. Its exact cause is unknown, although it is believed that the risk factors include a family history of the condition, increasing age, head injuries, and lifestyle (NHS, 2016). Because the researchers cannot determine the cause, it is difficult to design effective prevention strategies. However, several theories and approaches still exist, and I will describe them in detail in this essay.

There is a consensus that Alzheimer’s disease is caused by the complex interaction of different factors, such as age, genetics, the lack of exercise, and certain medical conditions (Alzheimer’s Association, n.d.). Because there is no single cause explaining the onset and progression of this disease, scholars have developed different theories and recommendations as to how it can be prevented. For example, it has been proved that the majority of people diagnosed with this irreversible condition also have cardiovascular problems (Alzheimer’s Association, n.d.). Although not all people with vascular problems develop Alzheimer’s, one may suggest that the timely prevention and treatment of cardiovascular disease may help reduce the risk of having dementia. It is important to understand, though, that clinicals trials continue, so no evidence-based recommendations in this relation are available.

Furthermore, some scientists argue that it is critically important to stay active and eat healthy foods to prevent the development of Alzheimer’s (Alzheimer’s Association, n.d.). Regular physical exercises have proven to be beneficial for all organs including the brain. Physical activity improves oxygen flow and trains the muscles, thus making a person feel stronger and healthier (National Institute of Ageing, n.d.). A diet full of fruits, vegetables, and whole grains is also important because it provides the body with all necessary vitamins and minerals. The main advantage of this prevention method is that both physical exercise and dieting contribute to the better well-being and physical strength, as well as reduced risks of diabetes and cardiovascular diseases.

Mental exercises are also believed to be beneficial for older people. Studies suggest that such activities as reading and writing, learning foreign languages, participating in educational programs, playing musical instruments, etc. allow people to train their brain regularly, which improves its overall functioning (NHS, 2016). Social interaction may also be useful, so it is recommended to spend more time playing games, walking, swimming, volunteering, and doing any other type of work that involves active communication with people. One needs to emphasize that further research is needed to prove the effectiveness of these prevention methods and their role in stimulating normal brain functioning. Along with this vital research, scholars are currently exploring innovative solutions to prevent and treat the disease, such as brain implants and advanced drugs (Ferreira et al., 2015).

Thus, one may summarize that Alzheimer’s is a complex form of dementia that affects mainly older adults. There is currently no treatment to reverse or stop the progression of the disease, and available drugs can only make symptoms less severe. Because scientists still do not understand the etiology of Alzheimer’s, they cannot design evidence-based prevention strategies that would work for all population groups. However, ongoing research gradually enhances our understanding of Alzheimer’s and allows developing more effective prevention methods, such as exercising and dieting, mental and social activity, and prevention of cardiovascular diseases.
