Word puzzles such as crosswords finally get some proof of yielding better brain function in later life. Researchers at the University of Exeter Medical School and Kings College London conducted a large-scale, robust online study that used the CogTrack and PROTECT online cognitive test systems to assess core aspects of brain function. The research finds that the more regularly participants puzzled, the better they performed on tasks assessing attention, reasoning and memory. In fact, the puzzlers had brain function equivalent to ten years younger than their age on tests of grammatical reasoning speed and short term memory accuracy. More than 22,000 healthy people aged between 50 and 96 participated the study. While researchers cannot yet say that crosswords give you a sharper brain, the research suggests that encouraging people to start playing word games regularly might improve their brain function. The research reveals a definite link between word puzzles, like crosswords, and memory and thinking skills, and researchers plan to pursue further research to determine how regular puzzle-working directly improves these skills.
