Alzheimer's Disease: What is it?

According to the National Institute on Aging dementia disease, Alzheimers disease is a progressive brain disorder that is the most common form of dementia. Alzheimers disease affects memory and thinking skills, and over time the disease progressively worsens. The Institute also states that the number of people with Alzheimers disease will double every five years beyond age 65.

Information provided by NIH Senior Health states that scientists have not yet fully determined what may cause Alzheimers . Probable causes may vary from one individual to another; however, it appears that increased aging is the highest risk factor for Alzheimers disease. NIH Senior Health also says that diet, exercise, chronic diseases such as heart disease and diabetes may also be components in the development of Alzheimers.

According to the Alzheimers Association at www.alz.org, it is possible for people under the age of 65 years old to develop the disease. This is known as younger-onset Alzheimers disease. The Alzheimers Association reports that an estimate of approximately 500,000 people in their middle age -- 30s 40s and 50s -- have developed Alzheimers disease or Alzheimers-type dementia.

According to NIH Senior Health, the initial symptoms of Alzheimers disease may sometimes be mistaken for characteristics associated with normal aging, such as forgetfulness or difficulty learning new things. However, if a person is struggling with memory loss and it becomes severe enough to interfere with their normal activities it may be the first sign of Alzheimers disease. NIH Senior Health points out that symptoms of Alzheimers disease vary from one individual to another and they can also be signs of another type of disorder; therefore, it is essential to consult your physician to make a proper diagnosis.
