A man with confusion and signs of a brain injury actually had an extremely rare condition diagnosed in just 50 people over the past century. The damage extended into his corpus callosum, a C-shaped bundle of nerve fibers in the brain that connects the left and right hemispheres. A man in Ireland was diagnosed with alien hand syndrome, an extremely rare condition in which a person's hand moves on its own uncontrollably. The affected hand, usually the left one, also doesn't have sensation and cannot feel anything it touches. The above CT scan image shows damage to the man's brain tissue, likely due to a stroke.
