Catalepsy

Catalepsy (from Ancient Greek "seizing, grasping") is a nervous 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 (waxy flexibility), 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 (such as that recounted in Plato's Symposium) 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.
Artistic depictions
In the arts, catalepsy is often used for dramatic effect, sometimes as a plot device.
Literature
In William Shakespeare's tragedy Romeo and Juliet, the kindly Friar Laurence (in the course of a botched attempt to help the lovers) provides Juliet with a catalepsy-inducing potion so effective that Romeo tragically imagines his beloved's deathlike trance to be actual death and poisons himself in despair just before she awakens from her stupor—leading her to kill herself with his dagger upon discovering his suicide.
In Alexandre Dumas, père's novel The Count of Monte Cristo, the Abbé Faria has fits of catalepsy from time to time, before eventually dying from one.

In Edgar Allan Poe's "The Premature Burial", the narrator develops catalepsy. He fears being mistakenly declared dead and buried alive, and goes to great lengths to prevent this. In another of Poe's short stories, "The Fall of the House of Usher", Madeline Usher has catalepsy and is buried alive by her unstable brother Roderick. Catalepsy is also depicted in "Berenice", thus becoming one of the recurrent themes in Poe's fiction.
In Poppy Z. Brite's Exquisite Corpse, the main character—Comptom, a serial killer facing a lifetime sentence—uses shamanistic techniques to induce catalepsy and, convincingly appearing deceased, is able to escape prison.

This is catalepsy!"
