1. Obesity from high-sugar and high-fat foods impairs memory and learning. Essentially, when these foods impair the brain (specifically the hippocampus) they fuel overeating creating a vicious cycle. This helps confirm previous links between middle-age obesity and the increased risk of Alzheimer’s disease and other dementias later.
2. Brain training has been shown to help breast cancer-related memory loss and mental slowness. A study from Indiana University found that brain training helped processing speed and memory performance for breast cancer survivors who had undergone chemo.
3. A new study out of Weill Cornell Medical College has shown that when a threat hits a teen's brain, they can't make the fear disappear like adults can. This ability is called fear extinction learning, and researchers believe that teens' lack of fear extinction learning may be what causes much of the anxiety and stress so often present during the teen years. In fact, one of the researchers said that anxiety disorders tend to spike during or just before adolescence.
4. According to Alex Schelgel, a brain researcher and author of a new paper in the Aug. 2012 issue of Journal of Cognitive Neuroscience, the adult brain can learn new things just like younger brains. Schelgel studied the brains of 27 Dartmouth students while they took a Chinese language course. He found actual changes in the structure of their brains.
5. You memory distorts an event every time you recall it. A new study shows that your brain changes in ways that can distort the next attempt at recall. In fact, your recall can get progressively less accurate to the point that your memory is untrue!
