CHICAGO — A brain region controlling whether we feel happy or sad, as well as addiction, is remodeled by chronic pain, reports a new Northwestern Medicine study. And in a significant breakthrough for the millions of Americans suffering from chronic pain, scientists have developed a new treatment strategy that restores this region and dramatically lessens pain symptoms in an animal model.The new treatment combines two FDA-approved drugs: a Parkinson’s drug, L-dopa, and a non-steroidal anti-inflammatory drug. The combined drugs target brain circuits in the nucleus accumbens and completely eliminate chronic pain behavior when administered to rodents with chronic pain. The key is administering the drugs together and shortly after an injury. As a result of the study’s findings, the scientists are pursuing a clinical trial. The treatment has the potential to prevent chronic pain if used early enough after injury, the scientists said. The study was published December 21 in Nature Neuro...

What their “lay” minds take in is that they have a child who will face struggles throughout his/her schooling and in life. Dyslexia never goes away. There is no medication to mitigate the symptoms; worse, it is an invisible disability which (if undiagnosed) subjects the sufferer to lots of misunderstanding and criticism for things over which s/he has not control. As parents research their child’s dyslexia and receive information from the experts, they come to understand many things that they want others to understand as well. Here’s 20 of them. 1. THEY READ DIFFERENTLY. The brain anatomy of a dyslexic child is different. The area that understands language operates differently than the average individual’s. The brain has to translate symbols on the page of a book (for example) into sounds. The sounds then have to be combined to make meaningful words. The parts of the brain that do...
