Use It or Lose It: Mind Games Help Healthy Older People Too

ScienceDaily (Mar. 27, 2012) — Cognitive training including puzzles, handicrafts and life skills are known to reduce the risk, and help slow down the progress, of dementia amongst the elderly. A new study published in BioMed Central’s open access journal BMC Medicine showed that cognitive training was able to improve reasoning, memory, language and hand eye co-ordination of healthy, older adults.

It is estimated that by 2050 the number of people over 65 years old will have increased to 1.1 billion worldwide, and that 37 million of these will suffer from dementia. Research has already shown that mental activity can reduce a person’s risk of dementia but the effect of mental training on healthy people is less well understood. To address this researchers from China have investigated the use of cognitive training as a defence against mental decline for healthy older adults who live independently.

To be recruited onto the trial participants had to be between 65 and 75 years old, and have good enough eyesight, hearing, and communication skills, to be able to complete all parts of the training. The hour long training sessions occurred twice a week, for 12 weeks, and the subjects were provided with homework. Training included a multi-approach system tackling memory, reasoning, problem solving, map reading, handicrafts, health education and exercise, or focussing on reasoning only. The effect of booster training, provided six months later, was also tested.
