While the exact causes of Alzheimer’s disease are not fully known or understood, as of 2015, scientists believe the disease is caused by several contributing factors including genetics, along with environmental and lifestyle factors. It is believed that age may also be a contributing factor.
Scientific research shows that changes in the brain due to age can damage neurons and contribute to the development of Alzheimer’s Disease. When caused by genetics, onset of the disease hits at an early age (between the ages of 30 and 60). Those who live active and healthy lifestyles, and possess brain-stimulating jobs, tend to be at less risk of developing Alzheimer’s Disease.
Gender, heart health and past brain injuries are also believed to play contributing roles in the development. Studies show women may run a higher risk than men. People who suffer with health issues such as high blood pressure, uncontrolled diabetes and high cholesterol levels may be more at risk than those who do not. Finally, research also shows that those who have endured a brain injury in the past are also more likely to develop Alzheimer’s Disease than those who have not. While research continues, there is no known cure for Alzheimer’s Disease.
