Alzheimer’s disease is the most common form of dementia, affecting over 3 million Americans annually. Researchers have made a breakthrough in understanding its link to cytomegalovirus (CMV), a common childhood infection.
A study published in December 2024 found that people with Alzheimer’s disease had CMV antibodies in their intestines, spinal fluid, brains, and vagus nerves. The findings suggest “complex” interactions between CMV and the body’s changes can increase the risk of developing Alzheimer’s.
CMV is common – more than half of adults have been infected by age 40. While it usually doesn’t cause issues, certain behaviors can lower its transmission risk, such as practicing good hand hygiene, avoiding contact with tears and saliva during kissing, and wearing condoms during sex.
There’s no clear answer on how to prevent Alzheimer’s disease, but lifestyle factors like regular exercise, a healthy diet, maintaining social connections, and avoiding head trauma may help reduce the risk. Consult with your doctor for personalized advice.
