An irreversible, chronic neurodegenerative disease, Alzheimer’s destroys brain cells and disrupts an individual’s thinking ability as well as memory. It is named after Dr. Alois Alzheimer who had first identified the disease in 1906. A fatal disease, Alzheimer’s affects every aspect of the patient’s life, changing the way they think, feel and act. While scientists haven’t been able to identify its exact causes, they do have a fair idea of their most common symptoms and risk factors of Alzheimer’s disease. An active, healthy lifestyle and good eating habits can reduce the chances of Alzheimer’s disease.
