Scientists discovered caffeine – the most commonly consumed stimulant in the world – increases cognitive reaction time and enhances concentration in people with attention weakening.
Caffeine is the most commonly consumed stimulant in the world – but its prospective to improve attention impairment in aging conditions, including dementia, is chiefly unfamiliar.
And so, the squad of scientists set out to define whether caffeine could have the same properties as the current licensed treatments for dementia.
They applied a blind, placebo-controlled design to sightsee whether caffeine could enhance performance on experimental and real world tasks of attention in healthy older people.
The study involved 20 healthy older participants, who completed tests over a nine-day period. Preceding the study, each of the members did not consume any caffeine for a week. The scientists then provided the participants either a caffeinated or decaffeinated tablet on alternating days.
