Drinking too many sugary beverages like soda, may increase the risk of Alzheimer's disease. In animal studies, researchers at the University of Alabama at Birmingham fed one group of mice a regular diet, and another group a diet with 10% sugar water. The sugar-fed mice had worse learning and memory retention than the other group, and their brains had twice as many amyloid (am-uh-loid) plaque deposits, a hallmark of Alzheimer's.
Lighting Up Bipolar Disorder
Bright light therapy could help ease bipolar depression for some patients. In a recent study, published in the journal Bipolar Disorders, women were given light boxes and taught how to use them at home. Six out of the nine women showed some response, and several of them reached a full recovery from their depressive symptoms. Participants who used light therapy midday fared better than those who used it in the morning. Researchers think this may be because people with bipolar disorder are very sensitive to morning light, and using the light box too early might disrupt their circadian rhythms.
Fantasize Cravings Away
Fantasies may help banish your cravings. Australian researchers asked participants to recall different sights and smells, like the scent of freshly cut grass. The participants' cravings for chocolate were reduced by 30%, even though the treat was right in front of them. The scientists say the brain can't handle new sensory imagery and cravings at the same time, so the craving disappears.
