Scientists have found compelling evidence that cognitive training can boost levels of a brain chemical called acetylcholine in people aged 65 or older. A 10-week study showed that doing mental exercises for 30 minutes a day increased acetylcholine by 2.3% in the brain area involved in attention and memory.
This increase is significant, as it’s estimated that acetylcholine levels decrease by 2.5% per decade with aging. The study suggests that cognitive training may turn back the clock by about 10 years, improving thinking and memory in older adults.
The research backs earlier studies on animals and people showing that brain stimulation can increase neurotransmitters like acetylcholine. BrainHQ, a scientifically-tested cognitive program, was used to deliver mental exercises that improved attention and speed of processing.
While previous programs have shown promise, this study provides more concrete evidence of their effectiveness. The findings suggest that even small increases in acetylcholine can have a profound impact on memory and thinking in older adults, making brain training an attractive option for staving off cognitive decline.
