Genetic Risks Of Getting Alzheimers

The onset of Alzheimer’s has minimal genetic links. A family history of Alzheimer’s can have an impact but of the two variants of Alzheimer’s the extremely rare Early Onset Alzheimer’s (FAD ) is the variant that have the strongest link to genetic influence. There are less than 200 known cases of this variant in the world so you are highly unlikely to develop the disease if a family member is a sufferer. There may be other factors in your environment that play a bigger part, but if your family member has the early onset variant, you need to know that over 50 percent of these cases are known to have been caused by genetic mutations.

Late Onset Alzheimer's, is the most common form of Alzheimer's by far, and tends to occur much later in life than FAD. That is, it can affect adults of any age, but it usually occurs after age 65.
This form Alzheimer's can affect people who may or may not have a family history of the disease.
There is currently no evidence that an inheritance of mutated genes causes Sporadic or Late Onset Alzheimer's. However, genetics does appear to play a significant role in the development of this far more common form of the disease. Naturally occurring variations in some of the genes in our systems can seem to cause the disease. Apolipoprotein E (APOE ), more specifically APOE e4 is the one to look out for. It does some useful stuff, but someone inheriting one or two copies of this particular variation needs to pay closer attention to any symptoms they develop – and should of course always do what they can to take preventive measures like exercises for both the brain and the body.
