� The Causes and Symptoms of Alzheimer's Disease

The actual cause of the disease is still unknown but several factors are believed to be responsible in the development of the brain disorder. The lack of neurochemical factors in the nerve cells is also one of the probable causes of this disease.

The genetics and aging problems are considered to be the main causes of Alzheimer's disease. There are approximately nine out of ten thousand people affected with this malady and it is more often in women than in men. The disease primarily occurs in older people over the age of 65. However, there is very little chance for developing Alzheimer's disease through inherited mutated genes.

The most common symptoms of the Alzheimer's are as follows:

Impaired memory and thinking: The person feels difficulty in remembering very common things like his personal information, such as his place of birth or his occupation.

Difficulty in performing familiar tasks: The person with Alzheimer's disease feels to have difficulty in performing his daily tasks i.e. eating, dressing, showering etc. A person who prepares a meal may forget to serve it or even can't remember whether he has prepared it.

Problems with communication: The person gradually feels difficulty in recalling words or understanding the meanings of common words.

Disorientation and confusion: Patients may get lost in his own familiar place. Recognizing familiar places and situations becomes impossible for them. They even can't understand simple commands or follow directions.

Poor and decreased judgment: The person feels difficulty in taking decisions. As the people affected are always in their own state of mind so they may also leave the house on a cold day without any winter garment or they may even go to the market wearing pajamas.

Misplacing and messing up with things: The person affected with A.D. usually forgets where he has kept his daily used things, such as glasses, keys, etc. The person may also mess up with things, such as breaking glasses, damaging house hold goods, etc.

Changes in behavior and personality: Patients have the tendency to swing their moods rapidly. The patients may even feel dramatic changes in their personality and can become fearful, angry, quiet, etc.

Become passive and lose interest: People generally tend to become passive and show no interest in their usual activities. Extra encouragement is required to make them become active.

Problems with abstract thinking: The person with Alzheimer's disease loves to spend lots of time alone in some lonely place and shows less interest in interacting with other members of the family. They sometimes show symptoms of abstract thinking and also even feel difficulty in recognizing numbers or understanding what to do with them.
