A new device similar to a pacemaker has been devised that may help patients suffering from dementia and traumatic brain injuries. It sends messages to the brain when it is struggling to remember but is quiet when it feels the brain is functioning well. Devices such as this have been used in the past but only for people suffering from seizures and Parkinson’s disease. The research is funded by the Department of Defense at the cost of $70 million dollars in the hope of relieving the stress of brain injuries suffered by soldiers. Impulses sent to a portion of the brain helped in a 15% improvement of word recall. Hope is that Alzheimer’s, as well depression and anxiety may be helped by targeting different areas of the brain with electrical impulses. Test subjects who showed greater recall said that they actually felt nothing physically when the brain was stimulated by these impulses.
