Catalepsy


Catalepsy is a neurological condition characterized by muscular rigidity and fixity of posture regardless of external stimuli, as well as decreased sensitivity to pain.

Signs and symptoms

Symptoms include a rigid body, rigid limbs, limbs staying in same position when moved, no response, loss of muscle control, and slowing down of bodily functions, such as breathing.

Causes

Catalepsy is a symptom of certain nervous disorders or conditions such as Parkinson's disease and epilepsy. It is also a characteristic symptom of cocaine withdrawal, as well as one of the features of catatonia. It can be caused by schizophrenia treatment with anti-psychotics, such as haloperidol, and by the anesthetic ketamine. Protein kinase A has been suggested as a mediator of cataleptic behavior. Unsuggested waxy catalepsy, sometimes accompanied by spontaneous anesthesia, is seen as an indicator of hypnotic trance. Suggested or induced rigid catalepsy, of extended limbs or even the entire body, sometimes tested with heavy weights, has been a staple of stage hypnosis shows and even academic demonstrations of hypnotism since the late 18th century, as proof of extraordinary physical abilities possible in trance states. Such demonstrations have also been performed by Asian martial artists and attributed to the pneumatic vital energy known as qi.

Historical cases

Armand D'Angour suggests that reports of Socrates, in about 429 BC, standing perfectly still for hours on end during the Athenian campaign against Potidaea while seemingly deep in thought, are "too extreme to be considered wholly a matter of rational choice," and that "it is reasonable to suppose that it was the symptom of an underlying physiological or psychological condition", such as catalepsy.
St. Teresa of Avila experienced a prolonged bout of catalepsy that began in 1539. This episode was precipitated by the stress she experienced at the Carmelite Convent of the Incarnation. Her legs became rigid, leaving her an invalid for three years. Teresa endured intermittent attacks of catalepsy from then on.
Rufina Cambaceres, an Argentine socialite, is well known in Buenos Aires for her tragic death in 1902. The 19 year-old girl experienced a bout of catalepsy on the day of her birthday, May 31, 1902. The night of her burial in the family mausoleum, the caretaker of La Recoleta Cemetery heard noises coming from her vault. He found the coffin was not in the right position, with scratch marks on the inside of the lid and the girl's face. Rufina had been buried alive. The reason for her bout of catalepsy has never been fully clarified but it is presumed that she died of suffocation after waking up.

Artistic depictions

In the arts, catalepsy is often used for dramatic effect, sometimes as a plot device.
