Alzheimer’s prevention studies in genetically at-risk individuals

Genetics & Alzheimer’s disease Scientists are still trying to determine the underlying causes of Alzheimer’s disease (AD). The hope is that one day we will be able to stop the disease from progressing or perhaps even prevent it altogether. To date, researchers have identified a number of genes that play an important role in AD. Some of these genes are simply risk factors for AD. Other genes are hereditary and will cause (with nearly 100% certainty) dementia due to AD to develop. There are two types of AD: early-onset and late-onset AD. Early-onset AD is rare, occurring in people age 60 and younger. This represents less than 5% of all...
