You will be relieved to learn: A team of French researchers have used brains scans to learn the cause of “writer’s cramp” (also known as “hand dystonia”). According to a report from Health Day, the findings — just published in the scientific journal Archives of Nerurology, “although prior research had already linked writer’s cramp to problematic alterations in the gray matter in certain brain regions, the current investigation identified problems with the white matter of certain nerve pathways in brain areas that are responsible for generating motor commands.”

All together now: Oh.
