Researchers are investigating this question right now. Some scientists believe genetics may play a role in AD, and genetic markers for the disease have been identified. Some people with the markers do not get the disease, while others without the markers do. Because of this variability, scientists believe that genetics may combine with other factors (such as viruses, environmental stresses, or imbalances in the immune system) to cause AD in some individuals.
