Spinal cord stimulation restores movement in the arms of stroke patients with locomotion problems, researchers report. The treatment has the potential to improve the quality of life for those who suffer arm paralysis following a stroke.
A genetic predisposition to oral health problems increased the risk of white matter hyperintensities and was associated with a 43% increase in microstructural damage in the brain. The study adds to the growing body of evidence connecting poor oral health to an increased risk of neurological disorders.
Transplanting intestinal epithelial stem cells from healthy donors reduced stroke-induced mortality, decreased the volume of dead brain tissue and gut leakiness, and prevented stroke-induced cognitive decline.
Those who exercise either early or late in the morning were 11% and 16% respectively at a lower risk of coronary artery disease. Those who exercise later in the morning were 17% less likely to have a stroke than those in the control group.
