Causes of Alzheimer’s Disease
Author: Mitamins TeamScientists do not yet fully understand what causes
Alzheimer's disease. Most likely there isn't one single cause, but several factors that affect each person differently. Age is certainly the most important known risk factor for Alzheimer's. The number of people with the disease doubles every 5 years beyond age 65.
Family history is another risk factor. Scientists believe that genetics may play a role in many Alzheimer's cases. For example, early-onset familial Alzheimer's disease, a rare form of Alzheimer's that usually occurs between the ages of 30 and 60, is inherited. The most common form of Alzheimer's is late-onset Alzheimer's, which occurs later in life, with no clear family history shown by patients.
However, several risk factor genes may interact with each other, and with non-genetic factors, to cause the disease. The only risk factor gene identified so far for late-onset Alzheimer's is a protein called apolipoprotein E (ApoE). Although everyone has Apo3, only about 15 percent of people have a form that increases the risk of Alzheimer's. It is likely that other genes may cause Alzheimer's, whilst some help prevent its onset, but they remain undiscovered.
Alzheimer's disease causes a general decrease in function for certain areas of the pain that control thinking, communication, and behavior. Some of the deterioration may be related to a loss of chemical messengers (neurotransmitters) in the /pain - acetylcholine, in particular - that allow nerve cells in the pain to work properly.
Some studies have recommended that zinc or aluminum could help in the
treatment of Alzheimer's disease symptoms, although more research is needed. Experts agree both zinc and aluminum play crucial roles in our diet, in improving memory and /pain function.
Scientists are looking at three stages
Family history
For a few families, there is a exact relationship between family history and Alzheimer's disease. While for others, a family history of Alzheimer's disease puts them at greater risk than someone with no family history.
The external environment
The cause of Alzheimer's disease may be in our environment -- possibly a little in the water, soil or air.
The internal environment
Alzheimer's disease may be caused by something within the body. It could be a slow virus, an difference of chemicals or a problem with the immune system.
