Catalepsy (from Greek κατάληψις "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.
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. 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.
Symptoms include: 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.
St. Teresa of Avila experienced a prolonged bout of catalepsy that began in 1539. This episode was precipitated by the stress she was suffering 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.
In Eugène Sue's The Mysteries of Paris, the villain Jacques Ferrand experiences a fit described as cataleptic in his final confrontation with Rodolphe, blinded by lamplight and hallucinating with visions of his fantasized Cecily.
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 (recreation of Jeffery Dahmer's life story) facing a lifetime sentence—uses shamanistic techniques to induce catalepsy, and, convincingly appearing deceased, is able to escape prison.
In Émile Zola's short story "La Mort d'Olivier Becaille" ("The Death of Olivier Becaille"), the title character is buried alive and notes that "I must have fallen into one of those cataleptic states that I had read of".
In Philip K. Dick's novel Now Wait for Last Year, Kathy Sweetscent becomes immobilized by withdrawal from JJ-180, an alien (and highly addictive) drug. "My God, Kathy thought as she stood gazing down at the record by her feet. I can't free myself; I'm going to remain here, and they'll find me like this and know something's terribly wrong. This is catalepsy!"
In film and television
In the soap opera La Traición, the main character, Hugo De Medina, has catalepsy. Later in the telenovela, it is revealed that his daughter, Aurora, has the same illness.
In Chavo del Ocho, the main character, El Chavo, would have cataleptic-like fits if frightened, where he would curl as if sitting down in a chair and become stiff. However, he could be healed by being splashed with water.
In two Star Trek: Deep Space Nine episodes, "Statistical Probabilities" and "Chrysalis", the character Sarina Douglas, a genetically-enhanced human woman, exhibits cataleptic symptoms. In "Chrysalis", Dr. Bashir promises to do everything he can to cure her of the disorder, and is ultimately successful.
In Isle of the Dead (1945), Katherine Emery's character suffers from a multitude of illness' that render her almost incapable of caring for herself. Of these many illness' she is subject to catatonic trances which inevitably lead to her demise.
