How It's Caused
====Alzheimers is a very complicated disease, however scientists believe that it can be caused by gene mutations in a few chromosomes, including 1, 21, or 14, meaning it is an autosomal disorder. The strain of Azheimer's that is inherited is known as //familial Alzheimer's//, or FAD. Another strain, which is actually much more common FAD, is //sporadic Alzheimer's disease//.There are other factors including high blood pressure, head trauma, inherited by a close relative. The risk for Alzheimer's is also larger for females, and the elderly.====

What It Does
====Alzheimer's causes a deterioration of the brain and its neurons because of the buildup of certain abnormal proteins. These include: Amyloid Precursor Protein (APP) caused by a mutation in chromosome 21, Presenilin 1, caused by mutation in chromosome 14, and Presenilin 2, caused by a mutation in chromosome 1. As the brain deteriorates, it loses memories like words, names, faces, or skills. For example, they may be unable to recognize their friends and family or remember their names. Someone who used to play guitar will forget how. As the disease progresses, the victim may become forgetful, may have a wandering mind, may seem antisocial or even violent at times. They will eventually lose simple everyday skills, become incontinent, and unable to care for themselves or be independent.====
