Alzheimer's Blood Test: Could It Help Slow Disease Progression?

Could Alzheimer's be predicted through a blood test?

Researchers at the Rowan University School of Osteopathic Medicine in Stratford, New Jersey identified a potential blood test that would help diagnose Alzheimer's disease--making it easier for health officials to treat and further prevent the progression of the problem. 

"There are significant benefits to early disease detection because we now know that many of the same conditions that lead to vascular disease are also significant risk factors for Alzheimer's," lead study author Dr. Robert Nagele, said in a news release. "People found to have preclinical disease can take steps to improve their vascular health, including watching their diet, exercising and managing any weight and blood pressure issues to help stave off or slow disease progression."

The blood test works by identifying thousands of antibodies that target cellular debris. Antibodies present in our body as biomarkers for certain medical conditions that may indicate disease-risk. And while each individual shows a different and unique antibody profile based on age and sex, the disease present in the body can cause several changes that reveal the specific type of condition.

Researchers are hopeful that a blood test for the illness could help with the early intervention of Alzheimer's, in some cases. There is currently no cure for the most common form of dementia--estimated to affect 1 in 3 seniors, according to the Alzheimer's Association.

Health officials recognize that the brain begins to change years before symptoms start to take surface. By detecting Alzheimer's antibodies at the preclinical stage, this would give patients an opportunity to change certain lifestyle habits that may increase risk, as well as receive treatment before symptoms appear.

"As osteopathic physicians, we constantly tell patients that a healthy lifestyle is the best medicine for preventing disease. We also know that many people tune out messages about nutrition and exercise until a health crisis gets their attention," added Jennifer Caudle, DO, assistant professor of family medicine at Rowan University. "I can't think of a single patient who wouldn't take steps to prevent the progression of Alzheimer's if they could directly affect their prognosis."

The initial onset of dementia can be slow or quite progressive, with symptoms relanging from memory loss, to behavioral changes and chronic confusion, as well as a host of other issues. If you or a loved one is noticing issues, contact your primary care physician for guidance.
