Alzheimer’s disease
July 10, 2008
Alzheimer’s disease (AD) is a brain disorder. It is named after the German physician Alois Alzheimer, who first describes it, in1906. It is the most common form of dementia (brain disorder) among the older people.
Alzheimer’s disease usually begins after age 60, and risk goes up with age. While younger people also may get AD but this is less common with younger ones. About 5 percent of men and women ages 65 to 74 have AD, and nearly half of those age 85 and older may have the disease. It is important to think, however, that AD is not a normal part of aging.
Many researches conclude that about 4.5 million Americans suffer from Alzheimer’s disease. Person having AD may face some mental problems. Nerve cells die in areas of the brain that are vital to memory and other mental abilities, and connections between nerve cells are disrupted. There also are lower levels of some of the chemicals in the brain that carry messages back and forth between nerve cells. Dementia is a common disorder which is affects the person’s ability of doing daily activities.
Alzheimer’s disease begins slowly. It involves the parts of brain that control thought, memory and language. Patients of AD may forget the normal things of daily routine. As time passed symptoms get worse in those conditions. Patient can face some difficulties like reading, writing and speaking. They may forget even the minor things like combing of hair and brushing. They can suddenly aggressive or anxious. In some cases of Alzheimer’s disease patient may wander away from home. It’s different from the mild forgetfulness normally observed in older people. The person may have trouble remembering the names and faces of family members – or even who he or she is. Depression, anxiety, and paranoia often accompany these symptoms.
