The most common genetic risk factor for Alzheimer’s disease (AD) disrupts the blood brain barrier, impeding oxygen and nutrient flow to the brain and exposing the brain to systemic toxins, according to a recent investigation led by scientists from the University of Rochester Center for Neurodegenerative and Vascular Brain Disorders [1].
Study Suggests Sleep Detoxes the Brain
A good night’s rest may literally clear the mind. Using mice, researchers showed for the first time that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. These results suggest a new role for sleep in health and disease. The study was funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the NIH.
Q&A: Is “Wheat Flour” Whole Wheat, And Why Does It Matter?
Question: Is whole wheat considered a whole grain? As I understand it, foods with a low glycemic index are supposed to leave you feeling fuller, take longer to digest, and have health benefits. I thought whole grains were supposed to do those things too, but I’ve also read on the Internet that there’s no difference between wheat flour and white flour. What’s the truth?
Berries May Help Prevent Age-Related Decline of Brain Function
With humans living longer than ever before, diseases associated with aging are becoming a major focus of medical research. Neurodegenerative diseases, such as Alzheimer’s disease, are a major source of concern to aging adults. This is because such diseases not only lead to death, they do so through a particularly frightening route that includes loss of independence, memory, function, and personality. All adults experience a decline in certain aspects of brain function as they age. Memory, speed of cognition, and reasoning are among the functions most affected [1]. The effects of aging on cognition appear to be due to atrophy of brain tissue in particular regions, especially the prefrontal cortex and parietal cortex [2], as well as decreased neurotransmitter levels.
