The Risk Factors of Alzheimer’s Disease

Alzheimer’s disease has affected many people around the world, but scientists are not yet understanding the causal factors of this disease. Recently, we only know that the abnormal condition in the brain cells, called as amyloid and tau which are deposited around and within brain cells, leads to Alzheimer’s symptoms.

Here are several factors that can increase the risk of Alzheimer’s disease:

1. Genetics and Family History

Genetics and family history have a role in increasing the risk of developing Alzheimer’s disease. The risk will be higher for those who have close relative such as siblings and parents who experience Alzheimer. Although genetic factor is known as one of the risk factors for Alzheimer’s disease. Scientists have not known the genetic mechanisms that cause the disease.

In some families, inheritance of a single gene is able to increase the risk of developing Alzheimer’s disease. It is better for those who have close relatives that developed Alzheimer, go to genetic counselling to get advice about the risk of Alzheimer’s disease.

2. Age

Although for about 10% of younger people are also at risk of getting Alzheimer’s disease. But the probability of developing Alzheimer’s increase as people grow older. Therefore, age factor is known as the biggest risk factor for the disease. However, research has shown that about 1 in 20 people who are under 65, have this disease.

The probability of developing Alzheimer’s symptoms will be doubled each five years after people have reached 65. But, since age is only one of the risk factors of developing Alzheimer’s disease, there are also many older people with age 90s still have good memories and never develop dementia.

This condition is related to the fact that as people grow older, the brain cells’ functions will decline which contribute to the neurons issues in the brain cells. The age – related changes in brain cells may cause inflammation, production of free radicals in brain cells, shrinking parts of the brain and so on.

3. Head Injuries

Although this claim is still need further research, but in several cases http://68.183.181.185, people who had experienced severe head injury are at higher risk of getting Alzheimer’s disease compare to those who never experienced several head trauma.

4. Poor Sleep Condition

Research has shown that the issues of poor sleep condition might be correlated to the increased risk of developing Alzheimer’s disease. Poor sleep condition or patterns are such as the difficulty of staying asleep or falling asleep.

5. Lifestyle Factors

Although this finding still needs further research, but in some cases. People with poor lifestyle have higher risk of developing Alzheimer’s disease rather than people with healthy lifestyle. Lack of exercise, smoking or regularly being exposed to smoke, and obesity are known as risk factors for Alzheimer’s disease.
