Older adults who did a short brain training program were less likely to develop dementia years later. The training helped them process visual information quickly and manage tasks efficiently.

Researchers found that older adults who took part in a short brain training program were less likely to develop dementia years later. This training, called speed of processing training, teaches people to rapidly spot visual details on a computer screen and manage increasingly complex tasks in less time.

The study involved 2,802 adults aged 70-77 who were randomly assigned to one of three cognitive training groups or a control group that received no training. Those in the training groups completed up to 10 sessions lasting 60-75 minutes over five to six weeks. About half were also randomly selected to receive as many as four additional booster sessions at 11 and 35 months after the initial program.

Twenty years later, researchers analyzed long-term outcomes. Among participants who completed speed training and booster sessions, 105 out of 264 (40%) were diagnosed with dementia. In comparison, 239 out of 491 (49%) people in the control group developed dementia. That represents a 25% lower incidence in the speed training group with boosters.

The findings suggest that a fairly modest non-pharmacological intervention can have long-term effects and may help reduce rising healthcare costs.

Previous studies had shown that cognitive training improved everyday thinking skills for up to five years. After 10 years, all three training types were associated with better daily functioning. Participants who completed speed training had a 29% lower dementia incidence at the 10-year mark compared to the control group.

Why It Matters

This study is important because it shows that simple brain training can have long-term effects and may help reduce healthcare costs in India. As the Indian population ages, this information can be used to develop effective interventions to prevent dementia.
