New found hope for Alzheimer's
Previous studies had reported increased levels of arachidonic acid and related metabolites in the hippocampus, the brain part commonly affected in Alzheimer's.

According to the study published in Nature Neuroscience, as excess levels of arachidonic acid overstimulates the brain, reducing the excess levels of the fatty acid can lessen AD-related neurological impairments in mice.

The study reported that the PLA2 enzyme is responsible for controlling the brain levels of the fatty acid.

Scientists are optimistic that even the incomplete blockage of PLA2 by drugs or dieting will help lower arachidonic acid levels and therefore hamper memory deterioration and other Alzheimer's-related changes.
