The origin and risk factors



The specific cause of Alzheimer's disease is still unknown. Among the risk factors associated with it include the environment and lifestyle, but also with more certainty, age and history of Alzheimer's disease factoring familial risk.

Age


Most people with Alzheimer's disease are over 65 years old. However, a diagnosis was made in some people in their forties or fifties. It is therefore important to refer a doctor as soon as any one or more symptoms.



Diabetes :

In recent years it is known that type 2 (adult) diabetes is a risk factor for Alzheimer's disease, largely due to the fact that the problems of blood vessels and heart problems associated with diabetes are also factors risk of Alzheimer's disease. It is also known that glucose is less well absorbed in the brain of a person with Alzheimer's disease, as is the case of diabetics whose bodies poorly assimilated glucose.

New research has shown that the inability of the brain affected by the disease may be due to the fact that it's in a diabetic Situation, even if the person is not diabetic in the ordinary sense. Indeed, it seems that in the brain of a person with Alzheimer's disease or insulin production is impaired for any reason, or brain cells become insensitive to insulin.

Down syndrome :

Most adults aged over 40 years with Down syndrome experience a deterioration of the nerve cells, symptoms similar to those of Alzheimer's disease. In these people, Alzheimer's disease usually appears around the fifties or sixties.

Mild cognitive impairment (MCI):

In DLB, the level of cognitive impairment or memory, or both, is higher than that recorded in the normal aging process, but it is not advanced enough to be able to speak of neurodegenerative disease or "Alzheimer's disease. "An estimated 85% of people who have been diagnosed with MCI will develop Alzheimer's disease within ten years, making MCI an Significant risk factor for the disease. As the researchers Trust that abnormal changes in the brain begin to produce 5 to 10 years before the appearance of visible signs of Alzheimer's disease, brain imaging could help Classify individuals with MCI most at risk of emerging the disease. Mark of DLB continues.  

Injuries to the head :

The head injuries, especially repeated concussions, are risk factors associated with later development of Alzheimer's disease.

Low levels of education :

Several studies have shown that people with less than six years of schooling are more likely to develop Alzheimer's disease. It is necessary to continue studies on the level of education as a protective factor to determine whether it is education or other education-related factors that are involved (eg, low income level).

Other risk factors :

In addition to the risk factors described above, the following have been described as risk factors for Alzheimer's disease: chronic inflammation (such as some forms of arthritis), past episodes of clinical Sadness, stroke or mini-stroke, high cholesterol, hypertension, stress, Shortage of brain exercise and obesity. There is also less convincing risk factors such as smoking, excessive alcohol and drug consumption.
