As of now, Alzheimer’s is not curable. Drugs to cure Alzheimer’s are being developed all over the world, but efforts have been made until now, but the drugs have not yet been developed. The current drug discovery is still able to control the development of Alzheimer’s disease, but of course, research is being intensified on the causes of Alzheimer’s disease. Alzheimer’s disease is thought to be related to viral infections. If it is indeed related to viral infections and efforts are made to treat these viral infections, it can be prevented and treated. So now the causes of Alzheimer’s and why it occurs are also being studied in depth, and we have to look forward to the results of these studies to tell us whether or not it can be cured. Alzheimer’s disease is partly related to genetics, and the key to whether Alzheimer’s disease can be cured or not is whether it can be prevented or not. Nowadays, research has found that some dementia can be prevented by controlling one’s weight effectively, keeping one’s mood relaxed, studying actively, keeping oneself in a variety of relationships with the society, actively participating in social activities, and maintaining a moderate amount of exercise.
