Resveratrol doubles the growth and development of neurons, in a lab animal model.

The hippocampus – the region of the brain responsible for memory, experiences structural changes that are thought to contribute to aging-related memory and mood impairments. Ashok K. Shetty, from the Texas A&M Health Science Center College of Medicine (Texas, USA), and colleagues employed a lab animal model to study the potential effects of resveratrol – an antioxidant that is found in the skin of red grapes, as well as in red wine, peanuts and some berries. Among rats given resveratrol, neurogenesis (the growth and development of neurons) approximately doubled (as compared to control rats); as well, the resveratrol-treated rats also had significantly improved microvasculature, indicating improved blood flow, and had a lower level of chronic inflammation in the hippocampus. Consequently, the team observed that spatial learning and memory improved in the resveratrol-treated rats, with the ability to make new spatial memories significantly declining among control rats at 22 to 25 months.  Observing that: “These results provide novel evidence that resveratrol treatment in late middle age is efficacious for improving memory and mood function in old age,” the study authors submit that: “Modulation of the hippocampus plasticity and suppression of chronic low-level inflammation appear to underlie the functional benefits mediated by resveratrol.”
