There is actually very little known about what exactly causes a knockout but many agree it has to do with minor trauma to the brain stem. This usually happens when the head rotates sharply, often caused by a strike. A common misconception is that a knockout is caused by compression put on the carotid arteries in the neck restricting blood flow, but this is in fact how a choke out works.[2] A basic principle of boxing is to defend against this vulnerability by keeping both hands raised about the face.
A fighter who suffers a concussion and becomes unconscious from a strike with sufficient knockout power is referred to as having been knocked out or kayoed (KO'd). Losing balance without losing consciousness is referred to as being knocked down ("down but not out"). Repeated blows to the head are known to gradually cause permanent brain damage, with Alzheimer- or Parkinson's-like symptoms, and in severe cases may cause strokes or paralysis. This is commonly known as becoming "punch-drunk". Because of this, many physicians advise against sports involving knockouts.[3]
