This is a nice study, and confirms earlier work by Tim Salthouse (University of Virginia [1]), looking at more than a thousand people (cross-sectionally), and evaluating their cognitive function and crossword puzzling activity. At every age, people who did more crossword puzzles had better cognitive activity - but the rate of cognitive decline was identical regardless of crossword puzzle use. This was interpreted (as in the current study) as showing that people who are sharper do more crossword puzzles - but doing crossword puzzles doesn't make a person shaper or change the rate at which a person becomes less sharp.
