As each people differ in their genes and lifestyle, the importance of these causes also differ from individual to individual in increasing or decreasing the risk factors that develop Alzheimer’s disease.

Changes in the brain due to age:

The disease, commonly found in older people, is due to age-related changes that take place in the brain, which may damage neurons and lead to Alzheimer’s.

Genes are also one of Alzheimer’s causes. Many early cases of Alzheimer’s are familial Alzheimer’s disease, which is caused by changes in one of three known genes inherited from a parent. The studies have also shown that the presence of the apolipoprotein E gene affects a person’s chances of the disease.

Habits such as non-smoking, less consumption of alcohol, active social life, and healthy diet have all decreased the chances of getting the disease while heart problems, obesity, blood pressure have increased the chances.

The studies have proved that there are no strict dimensions as to know what causes Alzheimer’s.
