Certain genes increase the risk of developing Alzheimer's disease. The side effects of the most common of these genes, apolipoprotein E, may be evident as early as in childhood, a study finds.
Genetic risks are just one of the factors that may increase or decrease a person's chances of developing Alzheimer's disease (AD), along with age and family history.
While the symptoms of the rarer early-onset AD - representing less than 5 percent of people with the disease - can appear from the age of 30, the symptoms of the more common type, late-onset AD, is apparent over the age of 65.
This study, published in the online issue of Neurology, finds that the effects of the AD gene apolipoprotein E (APOE) may possibly be seen before the age of 20.
