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.
In this simplified brain circuit, damage to orexin-secreting neurons in the hypothalamus can lead to inhibition of motor neurons, thus lowering muscle tone.. Cataplexy is considered secondary when it is due to specific lesions in the brain that cause a depletion of the hypocretin neurotransmitter.
It refers to the patient's body showing resistance to being moved. Alteration of an individual's posture is similar to bending a warm candle. [5] Waxy flexibility often develops with other symptoms of catatonia, including: Immobility: showing no signs of motion [6] Posturing: holding in an inappropriate body position for an extended period of ...
In the ICD-11, catatonia is defined as a syndrome of primarily psychomotor disturbances that is characterized by the simultaneous occurrence of several symptoms such as stupor, catalepsy, waxy flexibility, mutism, negativism, posturing, mannerisms, stereotypies, psychomotor agitation, grimacing, echolalia, and echopraxia. Catatonia may occur in ...
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.
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]
Autistic catatonia is a term used to describe the occurrence of catatonia in autistic people. [1] Catatonia is a complex behavioral syndrome typically characterized by immobility, withdrawal, abnormal movements, and abnormal behaviors.
