Alzheimer’s Information: Who’s at Risk for Dementia and Alzheimer’s Disease (Part 1)
The first and most agreed upon risk is age. It’s fairly easy for doctors to agree upon this risk factor because the majority of people who have Alzheimer’s are 65 and older. Also, the chances of developing the disease almost doubles for every five years after the age of 65. Once a person reaches the ripe old age of 85, the risk factor reaches almost fifty percent. Age is one of the unpreventable causes of Alzheimer’s disease.
Genetics and family history have always been thought to play a key role in the development of Alzheimer’s. However, that may be a misguided. Researchers found that the more individuals in a family who have Alzheimer’s, naturally the greater the risk for the rest of the family members. Also, people who have either a parent or a sibling with Alzheimer’s were two to three times more susceptible to the disease. The researchers were able to find the gene that virtually guarantees that a person will have Alzheimer’s, however, the only gene that is directly responsible has been found in only a few hundred families, and accounts for a small amount of cases. This leads scientists to believe that most Alzheimer’s cases are due to both genetic and non-genetic factors.
Head injuries may play a much bigger factor than expected in the development of Alzheimer’s disease, and thankfully it is one of the controllable risks. From what researchers have gathered, there is a very strong link between a major head injury and being at risk for Alzheimer’s. This means that anyone who has played a contact sport such as football or hockey will be more susceptible to Alzheimer’s. Do not misinterpret this as meaning that everyone who’s played a sport will get Alzheimer’s. It doesn’t really matter how you damage your head, as long as it gets banged up Alzheimer’s will have a higher chance of occurring.
