This has been a month of good news for two of my annoying habits.
The first is my penchant to watch sappy films from Indonesia. I lived in the country after college, and the films help me keep up my Indonesian language skills. A recent review of hundreds of dementia sufferers in India finds that dementia among speakers of multiple languages comes, on average, four years later than it does to people with dementia who are monolingual. Prior studies had found a similar phenomenon, but the new study shows that multilingualism likely postpones dementia regardless of a person’s class or formal education.
My next habit, forgive me, is singing along to musicals. A paper read this month at the Society for Neuroscience meeting in San Diego finds that when nursing home patients with Alzheimer’s disease sing along to The Sound of Music and The Wizard of Oz, they score better on measures of their cognitive abilities.
Monetary, emotional toll
The good news on dementia is a welcome tonic against some overwhelmingly frightening facts. Because we are adding, on average, at least two years to our lifespan every decade, we are all more prone to dementia. One’s chances of dementia double every five years after age 65; one of every two Americans older than 85 is afflicted with Alzheimer’s.
