Online brain training tied to decade‑equivalent boost in cholinergic function, McGill trial finds
Heather Vogel Fact checked
A double‑blind McGill University–led clinical trial reports that 10 weeks of BrainHQ exercises increased a PET marker of cholinergic function in healthy older adults by an amount the authors say roughly offsets about a decade of age‑related decline. The peer‑reviewed study used a specialized tracer to confirm the biochemical change.
