It is difficult to tell the difference between Alzheimer's disease and other types of dementia, especially early in the course of the disease, according to Dr. Nick Fox and associates from The National Hospital for Neurology and Neurosurgery in London.

NEW YORK (Reuters Health) - The limit set for a cancer-causing compound found in tap water may be too high, putting women at increased risk for bladder cancer, results of a study suggest.

According to the report, women who drank tap water that contained levels of nitrates below the maximum level of 10 milligrams (mg) per liter set by the US Environmental Protection Agency (EPA) were still nearly three times more likely to develop bladder cancer compared with women who consumed much lower levels of the contaminate.

NEW YORK (Reuters Health) - Studies have suggested that stress can be harmful for people with heart disease, but a new report finds that it may actually triple their risk of death.

The researchers said their study is the largest to date to investigate the relationship between stress response and mortality in heart patients. Other studies have found that stress can contribute to heart attacks.


Childhood Food Allergy Rarely Causes Death: Study

Mon Mar 25, 2002

NEW YORK (Reuters Health) - Many parents will be relieved to learn that food allergy-related deaths in children are much more rare than they might have thought, according to the results of a study.

While fears of peanut allergies have garnered much attention in the media, the study conducted in the UK found that no young children died as a result of a peanut allergy between 1990 and 2000. However, peanut-related deaths did occur in two older children in that country--one 13-year-old and one 15-year-old.

What's more, women who stop taking hormones do lose bone density, but no more rapidly than women who never took hormones, according to the report in the March 25th issue of the Archives of Internal Medicine.
