Crosswords and computers but not social outings may ward off dementia: Aussie study

Stimulating puzzles and writing letters may increase resilience against brain pathologies, authors say

Older adults who frequently use computers, write letters and take classes have a modest yet significant lower dementia risk than those less engaged with literacy-oriented activities, Australian research shows. 

Regular active mental stimulation in the form of crosswords, card games and chess were also linked with a reduced chance of dementia, according to the Monash University-led team in Melbourne.
