High Urate May Slow Parkinson’s

People with Parkinson’s disease may get worse at a slower pace if they have high levels of a substance called urate in their blood. That’s the conclusion of a study of 800 people with mild Parkinson’s. People with high urate levels were only half as likely as others to get much worse in a two-year period. They lost fewer brain cells that produce a substance called dopamine. Therefore, they did not need medicine to replace it. Researchers are planning another study that will give patients a supplement called inosine. The body converts inosine to urate. USA Today wrote about the study April 16. It was in the journal Archives of Neurology.

Depression May Raise Risk of Alzheimer’s

People who have been depressed may be more likely to develop Alzheimer’s disease later, a study suggests. The study included 486 people, ages 60 to 90. They did not have any form of dementia when the study began. In the next 6 years, 33 developed Alzheimer’s disease. In the study group, 134 people had consulted a doctor because they felt depressed. They were 2.5 times as likely to develop Alzheimer’s as others in the study. Researchers said the cause is not clear. More research is needed. The study was published April 8 in the journal Neurology.

DASH Diet Reduces Heart Attacks, Strokes

Women who follow the healthy “DASH diet” have fewer heart attacks and strokes, a study has found. The research used 25 years of data on 88,000 women. All were part of the Nurses’ Health Study. The DASH diet is a plan designed to reduce blood pressure. It includes twice as many fruits, vegetables and grains as the average American diet. About 15,000 women in the study ate in a way similar to the DASH diet. Their heart attack rate was 24% lower than the rate for women in the study who ate typical American diets. Their stroke rate was 18% lower. The Associated Press wrote about the study April 15. It was published in the journal Archives of Internal Medicine.
