Causes



There are 2 types of causes namely **Known Causes** and **Potential Contributing Causes**.


 * __Known causes__** are: 1. Age and 2.Genetics:

Research and studies have shown that age is the single greatest risk of Alzheimer’s as 5% of the

people aged between 65 and 74 have the disease. Half of people 85 years and older are said to have

the disease. Genetics: research has shown that a child has 50/50 chance of developing Alzheimer’s if

one of the parents has it, which is a very high odd. This is mainly due to a gene that mutated inherited

from one parent. According to the American Health Assistance Foundation,5% cases of Alzheimer’s

thought to be from genetics, the symptoms usually appear between the ages of 30 to 60 years.
 * __Potential Contributing causes__:**

There are 4 potential contributing factors namely **cardiovascular disease**, **Type 2 diabetes**, stroke, high blood pressure and high cholesterol. High blood pressure can damage blood vessels in the brain and high cholesterol prevents blood to clear protein from the brain which also damages the brain. Inflammation- insulin does not convert blood sugar into energy, which causes high blood sugar in the brain that damages it. Oxidative is caused by unstable molecules or energy bonds from chemical reactions. These molecules end up seeking stability by looking for other molecules and attaching with them causing tissues and brain cells to damage thus affecting the brain. Also other factors include severe head injuries and lower education level.
 * oxidative damage** and **inflammation**. Cardiovascular disease includes things like heart disease,
