NEW YORK – Here is a look at this week’s top medical stories.

Dementia and cognitive impairment are more prevalent among seniors who live in rural settings, according to a new study published in the American Journal of Preventive Medicine. 

Researchers say education, specifically graduating from high school, appears to protect against cognitive impairment.

Nearly a third of high school seniors report using some kind of vaping device in the last year, according to an annual government survey.

The report also finds vaping and marijuana are more popular among twelfth-graders than traditional cigarettes or misused prescription pain killers.

British researchers say drinking a hot cup of tea a day could lower the risk of developing glaucoma.

The study also showed that other beverages like iced tea, soft drinks and coffee had no effect.  Glaucoma is one of the leading causes of blindness.
