Catalepsy - Definition

Ask a question


Catalepsy is defined by a one-time loss of voluntary muscle contractions in the body. The position of the cataleptic is similar to that of statues. The body stops in mid-movement and is frozen in its action. Muscle contraction is involuntary in cases of catalepsy and a major tensing of the muscles then prevents changing the spontaneously adopted position. Catalepsy may be psychological particularly in the context of diseases such as schizophrenia and hysteria. It may also be neurological when caused by a brain tumor or Parkinson's, among others. Catalepsy could be artificially induced by hypnosis.
