Mental Workouts >

Abacus solutions trigger a flurry of mental activity and abacus-based mental calculations are a powerful mental workout. It is reasonable that the multi-sensory, multi-modal brain activity associated with doing arithmetic with an abacus, and especially doing challenging mental calculations, would have brain-boosting cognitive benefits. It's true, it does!
In Japan, the soroban has been used to help seniors maintain their cognitive function. They use the abacus to fight dementia, Alzheimer's disease, and mental-decline in the elderly.
