Media coverage about the crossword and dementia is completely black and white: crosswords are either the brain’s secret weapon or they’re a gigantic waste of time.

He methodically and religiously worked his way through each one, from the crossword to the jumble to the cryptoquip, a substitution cipher that asks solvers to decode clues and figure out the pun.Įxtroverted and spontaneous Murray, a successful businessman and local politician, also had his morning routine: coffee with lots of sugar oatmeal and tinkering on one of his many writing projects, such as a loosely autobiographical musical about a traveling salesman.
