Current Research on Genes and Alzheimer's
Learning more about the role of APOE e4 and other risk factor genes in the development of Alzheimer's disease may help scientists identify who would benefit from prevention and treatment efforts. Age, still the most important known risk factor for Alzheimer's disease, continues to be associated with the disease even when no known genetic factors are present. Alzheimer's research focusing on advancing age may help explain the role that other genes play in most cases of Alzheimer's disease.
Many Alzheimer's disease researchers are studying the genetics of Alzheimer's disease. In addition, researchers, ethicists, and healthcare providers are developing policies about the appropriate use of genetic testing and counseling for Alzheimer's disease.
