Most experts don't routinely recommend genetic testing for late-onset Alzheimer's. In some instances of early-onset Alzheimer's, however, genetic testing may be helpful. Usually, health care providers don't test for APOE genes. The results can't fully predict who will get Alzheimer's disease.

Genetic testing for Alzheimer's disease. Genetic tests are not routinely used in clinical settings to diagnose or predict the risk of developing Alzheimer's or a related dementia. In some cases, if a person has symptoms at an early age with a strong family history of Alzheimer's, a neurologist or other medical specialist may order a genetic

Yes, genetic factors for Alzheimer's disease have been identified. The ε4 variant in the APOE gene is the most common genetic variant associated with an increased risk of late-onset Alzheimer's disease. Having one copy of the ε4 allele increases risk 3-fold, and two copies of ε4 increases risk 8- to 12-fold.

Who should consider genetic testing. We don't routinely recommend genetic testing for late-onset Alzheimer's disease because it has many causes and is unlikely to be due to variants in single genes. However, testing for early-onset Alzheimer's disease may be helpful depending on your family history and if you develop symptoms at an early age.
