A recent study has found that people who do puzzles and crosswords may hold off dementia for longer but experience a more rapid decline once the disease sets in. There has long been speculation that “exercising” your brain using brain training methods could protect against Alzheimer’s, but there has been hardly any evidence to back this up.
The research team were from the Rush University Medical Center in Chicago and they recruited 1,157 people aged over 65 in the early 1990s.
The study has come out with a conclusion that doing puzzles and crosswords does delay dementia, but can increase the disease once it has set in.
