Is a chronic disorder that affects mental processes. It is usually caused by a brain disease such as Alzheimer or a stroke. This causes damage to the brain cells and as these brain cells start to lose there functions the individual begins to be affected causing; low concentration, memory loss, impairment, depression and personality changes.
