Treating high blood pressure may also decrease the risk of dementia, new research suggests. The study included 774 deceased men who had high blood pressure while alive. Autopsy results showed fewer signs of dementia in the brains of men who had been treated for the condition. They had less brain shrinkage and fewer areas of brain cell death caused by mini-strokes. They also had fewer amyloid plaques and tangles, signs of Alzheimer’s disease. Treating high blood pressure can decrease the risk of strokes. But it’s unclear why treatment would prevent Alzheimer’s disease. Another surprise was that the men treated with beta-blockers had the healthiest looking brains. Beta-blockers are less effective than some other blood pressure medicines. But for those who used them brain damage was about half as severe as that for men who used other treatments.

The answers to a few questions can help doctors figure out which teens are most likely to drink alcohol at an early age, a study suggests. The study included 820 teens, ages 14 through 17. All were part of a larger study of alcoholism risk in families. They were interviewed using a standard format related to alcoholism risk. They also completed a questionnaire related to behavior. The teens were asked at what age they had their first whole drink of alcohol (such as a full can of beer). Those who said they already had a complete drink of alcohol were more likely to say their best friends drank. They were also more likely to have family members with alcohol problems. And they were more likely to have social, conduct and school problems. The journal Pediatrics published the study January 7.
