It cannot be diagnosed by the examination of the brain of the living organism, but after the death of patients their autopsy show the formation of plaque and tangles. Plaques are formed between the dying cells with accumulation of the protein called β-amyloid. Tangles are formed within the neurons cells due to the disintegration of protein. So due to death of the brain cells the patient brain shrink and they contain fewer brain cells and connection as compared to the normal human being. There are several risk factors involved such as, aging, unhealthy lifestyle, family history, Down syndrome, women are more likely to develop Alzheimer than men as they live longer, obesity and heart diseases.
