Antioxidant intake may help prevent Alzheimer's disease, suggests study

Unlike the current set of invasive and expensive tests used to diagnose Alzheimer's disease, the oxidative markers discovered by Professor Ramassamy's research team can be detected by a blood test. These markers are found in plasma extracellular vesicles, which are pockets released by all cells in the body, including those in the brain.

The research team focused specifically on the "sporadic" Alzheimer's disease, the most common form of the disease which results primarily from the presence of the APOE4 susceptibility gene. This same form of the disease had been studied by the team for other early markers.

"By identifying oxidative markers in the blood of individuals at risk five years before the onset of the disease, we could make recommendations to slow the onset of the disease and limit the risks", scientists noted.

This breakthrough brings new hope to Alzheimer's research. Once the disease is symptomatic, it is difficult, if not impossible, to reverse it.
