- Diet and Alzheimer’s Disease
A small study published in the June 2011 issue of the Archives of Neurology suggests that a diet low in saturated fat that also emphasizes foods low on the glycemic index may help reduce the risk of Alzheimer’s disease. The investigators compared the effects of a diet high in saturated fat and simple carbohydrates with those of a diet low in saturated fats and simple carbohydrates in 20 older adults who were healthy and 29 seniors who had specific memory problems considered precursors to Alzheimer’s disease. After four weeks, they found in the healthy group that the diet high in saturated fat and simple carbs elevated substances measured in blood that indicate presymptomatic Alzheimer’s, while the diet low in saturated fats decreased cholesterol levels and other biomarkers of Alzheimer’s disease. However, the low saturated fat diet had no such beneficial effects on participants who already had memory problems. The researchers said that the different results of the healthier diet among participants with some memory problems may have been due to the diet’s short duration. - Tinted Glasses to Fight Migraines
If you have migraines preceded by a visual aura (such as flashes of light or intense patterns) special precision tinted lenses may help stave off headaches. The lenses have to be custom made for every patient, according to a researcher at Michigan State University who just published results of a small study. The research demonstrated that the specially tinted lenses helped normalize brain activity that occurs when migraine patients experience auras of patterns and light. The clinical trial included only 22 participants, 11 of whom suffered from migraines and 11 who did not. During the study, each participant was asked to wear precision lenses. By using functional magnetic resonance imaging (fMRI) the researchers were able to monitor the effects of wearing the lenses on abnormal brain activity (known as hyper-activation) that occurs with the visual patterns associated with migraines. The results showed that the migraine patients reported 70 percent less pain when wearing the special lenses. The study was published in the May 26, 2011 issue of Cephalalgia. Larger studies with more migraine patients are now needed to confirm the positive results seen in this small group. More information on treating migraines.
