(July 15, 2009 - Insidermedicine) From Vienna - According to research presented at the International Conference on Alzheimer's Disease, physical activity may slow cognitive decline. In a study of over 3,000 people aged 70 to 79, researchers found that regular activity, such as walking 20 to 30 minutes per day, resulted in higher scores on the Modified Mini Mental State Examination. Similar benefits were still seen in those whose physical activity levels fluctuated. From California - According to research in the Archives of Ophthalmology, laser treatment for diabetic retinopathy may produce an effect that mimics glaucoma. In a study of over 120 patients, researchers found that photocoagulation may cause abnormal thinning of the retinal nerve fiber layer. This outcome may be mistaken for glaucoma, due to a loss of visual sensitivity similar to that caused by glaucomatous damage. And finally, from Copenhagen - According to research in the Journal of the American Medical Association, hormone therapy may increase the risk of ovarian cancer. In a review of ovarian cancer cases, researchers found that current hormone users had a 38% increased risk of the disease, compared with those who had never undergone hormone therapy. This was the case regardless of dose, formulation, route of administration, or duration of use. For Insidermedicine in 60, I'm Dr. Susan Sharma.
