When a nerve is injured, it's often hard to get it to regrow fast enough to restore function.
But now researchers say they can speed up that process, so that damaged nerves can be healed in days instead of months — at least in rats.
The scientists say they've developed a technique that reconnects the severed ends of a nerve, allowing it to begin carrying messages again very quickly. Usually, severed nerves must regrow from the point of injury — a process that can take months, if it ever happens.
After taking nearly two decades to root itself in the popular consciousness, the mysterious neurological condition Asperger’s Syndrome may soon be history - proposals for the fifth edition of the psychiatrist’s bible, The Diagnostic and Statistical Manual of Mental Disorders, or DSM five, recommend filing Aspergers under the general category of autism spectrum disorder.
