Arachidonic acid protects against Alzheimer’s disease

Arachidonic acid diet attenuates brain Aβ deposition in Tg2576 mice.

Because of its ability to form brain plaques, the amyloid β-protein is believed to play a key role in the development of Alzheimer's disease. This study evaluated the effects of arachidonic acid, an omega-6 fatty acid, on the deposition of amyloid β-proteins in the brain. For 9 months, mice were treated with a diet containing arachidonic acid. The results showed that the treatment with arachidonic acid prevented amyloid β-protein deposition in the brain. Further details can be found in the study.
