article imageBlood test for Alzheimer's disease may hit market soon

By KJ Mullins     May 4, 2011 in Health
A study from Research Institute of the McGill University Health Centre has found that a biochemical diagnosis can identify patients with Alzheimer's disease in the early stages. The blood test could be at your doctor's office soon.
"Until now, there has been no definitive diagnostic tool for Alzheimer's, other than postmortem analysis of brain tissue," said senior author Dr. Vassilios Papadopoulos, director of the MUHC Research Institute in a press release. "Our clinical study shows that a non-invasive blood test, based on a biochemical process, may be successfully used to diagnose Alzheimer's at an early stage and differentiate it from other types of dementia."
The blood test is based on the production of a brain hormone called dehydroepiandrosterone (DHEA). When the blood samples of patients without Alzheimer's is oxidized DHEA production is promoted. However when the blood of a patient with the disease is tested there is no increase of DHEA.
This test found that even in the earliest stages of the disease a diagnosis can be made.
Finding out in the earliest stages of Alzheimer's disease can lead a patient to take part in clinical trials.
The study 'A lead study on oxidative stress-mediated dehydroepiandrosterone formation in serum' was published in the Journal of Alzheimer's Disease.
