Acute confusion / excited delerium syndrome
An acute arousal state is also called an excited delerium syndrome. It is a state of being that is usually caused by excessive drinking or drug use. Often stimulants are involved, like cocaine. The excited delerium syndrome is a life-threatening situation that requires immediate intervention by professional care providers. You can recognize it by very restless and aggressive motorically behaviour. The victim flails around and is unable to calm down. The aggression is not directed, but at random. You can’t make contact with the victim. The victim keeps fighting even when he/she is overpowered by police or security.
Because someone behaves like this, it is easy to imagine that security or police want to overpower someone by pressing him or her down or holding him/her (fixation). However, this is dangerous and can lead to death. The moment you stop someone with excited delirium syndrome, the person will only resist harder, causing the heart rate/blood pressure to continue to rise dangerously.
