The benefits of cognitive training in older people may last as long as a decade, according to a study in the Journal of the American Geriatrics Society.
In 2007 a large federally sponsored study found improvements in people (average age 74) who had undergone 10 training sessions over 6 weeks for memory, reasoning or speed of mental processing, plus four booster sessions, compared to a no-training group. Even five years later, people who got training of any kind showed less decline in those cognitive skills.
Ten years have now passed, and the new study found that some of the benefits have persisted. People in the training groups reported less difficulty with daily tasks than the no-training group. Training in reasoning and speed-of-processing had residual effects, but not the memory training.
