Fun Fact: Lower Alzheimer’s Protein Levels Correlate with Life Long Brain-Stimulating Habits

The next time someone asks you to “stop playing with that puzzle or to put that book away,” tell them you are helping to stave off Alzheimer’s disease. A new study shows that older people who have life-long brain activities such as going to the library, reading books or newspapers, and writing letters or email, have lower levels of beta-amyloid in the PET scans. Beta-amyloid accumulation has been correlated with the progression of Alzheimer’s disease and this is the first time that life-long cognitive thinking has been related to a decrease in this protein. “What our data suggests is that a whole lifetime of engaging in these activities has a bigger effect than being cognitively active just in older age," said Dr. Landau.
