Happiness can be infectious, and now researchers from the University of California San Diego say they can document it. By looking at years of data collected from the Framingham Heart Study, researchers looked at self-reported happiness ratings and found out that happiness spreads among people up to three degrees removed from one another. The study found that you are 15% more likely to be happy if a direct connection is happy, 10% if a friend of a friend is happy, and 6% if it’s a friend of a friend of a friend. Sadness, too, can spread, albeit more slowly.

New insight into Alzheimer’s disease was reported by researchers at the Karolinska Institute this week. Scientists studying mouse models of the disease showed that when mice were fed with fast food products high in fat, sugar and cholesterol, they developed more “brain tangles” that lead to development of Alzheimer’s. These tangles of protein that develope in the brain are one of the hallmarks of the disease. Even though this is a mouse study, and the results may not necessarily be translated to humans, it’s yet another reason to consume less fast food and processed foods.

A Brown University study of European households finds an association between depression and the presence of mold in the home. The risk for depression increased by about 40 percent among people who lived in moldy homes, said lead research author Edmund D. Shenassa. It is as yet unclear what the relationship between the two is - does mold actually cause depression, or are depressed people more likely to not clean their homes and allow mold to grow? The U.S. government has not established general guidelines for acceptable levels of residential mold. And no study has conclusively linked mold exposure to mental health problems.

Johns Hopkins University Researchers report today that the percentage of patients who visit psychiatrists for psychotherapy (talk therapy) have declined from 44% in 1996-97 to 29% in 2004-05. They attribute this decline to an increase in use of medications as well as changes in insurance company policies - most psychiatrists receive less reimbursement dollars for a 45-minute visit than for three 15-minute visits. However, the study did not consider visits to health professionals who are not doctors but still provide talk therapy. Full story.
