Jan. 31, 2013 A team of scientists from Canada, Thailand and Morocco have found that DHEA-S may prevent neurocognitive impairment that affects a significant percentage of AIDS patients. In a report appearing in the February 2013 issue of The FASEB Journal, they describe how a network of steroid molecules found in the brain, termed "neurosteroids," is disrupted during HIV infection leading to brain damage. This suggests that treatment with one of these steroid molecules, called DHEA-S, may offset the disruption caused by the virus to prevent or reduce brain damage. "From these studies, we have gained a better understanding of how HIV injures the brain during AIDS, together with developing a new treatment approach for the resulting neurological disabilities arising from HIV/AIDS," said Christopher Power, M.D., co-author of this study from the Department of Medicine at the Medical Research Centre at the University of Alberta in Edmonton, Canada. To make their discovery, Power and colleagues initially found that neurosteroid enzyme levels were suppressed in the brains of people with HIV/AIDS and that a neurosteroid molecule, DHEA-S, prevented damage to cultured brain cells (neurons) caused by HIV. Then, using an animal model of AIDS, they showed that treatment with DHEA-S prevented … Continue reading
