Catalepsy (from Ancient Greek katálēpsis, κατάληψις, "seizing, grasping") is a neurological condition characterized by muscular rigidity and fixity of posture regardless of external stimuli, as well as decreased sensitivity to pain.
Cataplexy without narcolepsy is rare and the cause is unknown. The term cataplexy originates from the Greek κατά ( kata , meaning "down"), and πλῆξις ( plēxis , meaning "strike") [ 4 ] and it was first used around 1880 in German physiology literature to describe the phenomenon of tonic immobility also known as " playing possum " (in ...
Additionally, autoimmune diseases that are not exclusively neurological can cause neurological and psychiatric symptoms including catatonia. For instance, systemic lupus erythematosus can cause catatonia and is thought to do by causing inflammation in the blood vessels of the brain or possibly by the body's own antibodies damaging neurons.
Catalepsy is a nervous disorder characterized by immobility and muscular rigidity, along with a decreased sensitivity to pain. Catalepsy is considered a symptom of serious diseases of the nervous system (e.g., Parkinson's disease, Epilepsy, etc.) rather than a disease by itself. Cataleptic fits can range in duration from several minutes to weeks.

The exact cause of catatonic depression is not fully understood. [1] However, it is believed to arise from a complex interplay of genetic, biochemical, and environmental factors. Some research suggests that disturbances in neurotransmitters like dopamine and gamma-aminobutyric acid (GABA) may contribute to the development of catatonic symptoms. [2]
Cadaveric spasm, also known as postmortem spasm, instantaneous rigor mortis, cataleptic rigidity, or instantaneous rigidity, is a rare form of muscular stiffening that occurs at the moment of death and persists into the period of rigor mortis. [1]
