Flat Brained

Flat Brained (Flatius Branium) is a common condition where the victim goes into a nearly catatonic state and shows no signs of brain activity, unable to achieve basic cognitive thought and anything above basic involuntary muscle work. Victims tend to constantly say and do utter nonsense and continue to do such until their vital organs eventually shut down.
