Ever wake up to your partner yelling, laughing, or even throwing punches in their sleep? Scientists now say acting out your dreams could be an early sign of dementia. A new study found that people with REM sleep behavior disorder (iRBD) tend to have a slow but steady decline in memory and attention—even if they don’t develop full-blown dementia. Bonus fact: women seem to handle it better than men. Sleepwalking, but make it science! #Health #MentalHealth #SleepScience
