BATTLE DEMENTIA & ALZHEIMERS Older adults who regularly take part in word and number puzzles have sharper brains, according to the largest online study to date. The more regularly adults aged 50 and over played puzzles such as crosswords and Sudoku, the better their brain function, according to research in more than 19,000 participants, led by the University of Exeter and King's College London. Dr James Pickett, Head of Research at Alzheimer’s Society, said: This research, much like research we’ve seen in the past, suggests that regularly enjoying word and number puzzles has a positive impact on thinking skills.
