Brainworm (Parelaphostrongylus tenuis) is a roundworm or nematode normally found in the venous sinuses and subdural space of the brain of white-tailed deer in eastern North America. In advanced cases, the animal often walks aimlessly or in circles, and may carry its head in a tilted position. The disease is generally progressive and terminates in death, although there may be short periods of remission when the animal appears quite normal. This is what it looks like in action. Very unfortunate...
