The cause of Alzheimer's is the slowly progressing destruction of nerve cells in the brain. In reality it is natural to loose a certain number of nerve cells during ageing but this loss occurs much more rapidly in people suffering from Alzheimer's disease. As a result the brain of the patient does not function normally. In some cases the disease is caused by genetic mutations. In these cases symptoms usually occur before the age of 60 and take act rapidly. All presently known mutations are a result of an overproduction of a protein, which destroys the nerve cells. In most cases the exact cause remains unsolved. Each person is at risk of developing this disease.
Several genetic factors are known to increase the possibility. These include a normal modification of the gene Apolipoprotein E that encourages the deposit of the destructive protein. The probability of developing Alzheimer's disease increases with age. Alzheimer's is a disease that affects your brain causing you to forget things and effectually make you insane. In the early stages memory loss becomes more noticeable, concentrating and paying attention becomes more difficult, which leads to difficulties in understanding written material. Also another symptom would be misplacing or losing valuable items. Alzheimer's affects nearly 25% of people over eighty. .
With Alzheimer's also comes disorientation in familiar surroundings, changes in personality and judgment. Alzheimer's is a serious disease with three phases, mild, moderate, and severe. When the disease hits the moderate peak the victim will begin to forget recent events and some details of their normal personal lives, followed with trouble speaking, difficulty planning meals and dressing, along with disorientation, agitation, anxiety, suspiciousness, confusing day and night, and forgetting friends and relatives. A common thing to happen with Alzheimer's is people wandering off and getting lost.
