McGill University researchers found that brain training exercises can boost production of acetylcholine, a chemical crucial for memory and attention. The INHANCE trial studied 92 healthy adults aged 65 and older for 10 weeks. Participants using BrainHQ exercises showed a 2.3% increase in acetylcholine production in the anterior cingulate cortex, a brain region vital for learning and memory. Those playing entertainment games showed no significant change. “I’ve always believed that there are things that you can do that have a positive impact on brain health,” said senior author Dr. Etienne de Villers-Sidani from The Neuro at McGill. “Now I’m even more sure with what we’re seeing, that [brain training] has a profound impact on the health of key brain chemical systems.” (Story URL)
