Healthcast: Obesity and Alzheimer’s disease

Doctors may be one step closer to being able to predict risk of Alzheimer’s disease. 

Researchers looked at lifestyle data and brain images of more than 1,500 adults over a seven-year period. 

Smoking and obesity were linked to lower memory retrieval as well as social and emotional behavior. 

Alcohol use and diabetes showed smaller total brain volume. 

New research suggests very premature or low birthweight babies are at a higher risk of becoming introverted and anxious as an adult. 

A British study found babies born before 32 weeks or under three pounds were more likely to avoid taking risks and showed autistic spectrum behaviors. 

According to experts, this could be an effect of both biology and overprotective parenting.
