(CBS)- There is growing evidence that obesity raises the risk of dementia. Now a study in the British Medical Journal finds that when a person is overweight is key. Researchers studied the records of thousands of obese hospital patients. For people in their thirties the risk of developing dementia was more than three times higher than for people of normal weight. The risk was lower for patients who became obese at a later age.
(CBS)- A major clinical trial could change the way doctors treat depression. A study in Jama Psychiatry finds a combination of cognitive therapy and antidepressant medication is most effective for treating severe, non chronic depression. Researchers say patients are 30 percent more likely to recover when treated with that combined approach compared to those who only take antidepressants.
(CBS)- Exercise may protect older women from developing an irregular heartbeat. Researchers at Stanford University studied the exercise patterns for thousands of women between the ages of 50 and 79. Those who were the most physically active cut their risk for atrial fibrillation by 10 percent. Their level of exercise was the equivalent of walking briskly for 30 minutes, six days a week.
