Summary
A McGill University study of 92 adults ages 65+ found that 10 weeks of BrainHQ cognitive training increased acetylcholine production by 2.3% in the anterior cingulate cortex, a region tied to memory, attention, and learning. Using PET scans, researchers showed that the brain-training group improved while controls who played standard games did not. The INHANCE trial is the first to link cognitive exercises to improved cholinergic function, which naturally declines with age. Experts note that adaptive, challenging tasks—not casual games—drive these benefits. Despite limitations, findings suggest targeted brain training may help older adults maintain cognitive health.
