Docosahexaenoic acid may protect against the accumulation of a protein believed to be linked to Alzheimer's disease

Docosahexaenoic acid (DHA), an omega-3 fatty acid, may protect against the accumulation of a protein believed to be linked to Alzheimer's disease, according to the results of a new study published in the March 30, 2005 issue of The Journal of Neuroscience. The study used Martek DHA, which is produced from microalgae.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.
