![]() It can affect completely healthy people who have never had a seizure before in their lives.Ĭataplexy can cause a mild and temporary weakness in the subject with limb failure that usually lasts a few seconds, but it can also cause complete muscle atony that can last up to 30 minutes or more and give the illusion that the patient has even died.ĭuring the cataplectic episode, the patient remains fully conscious of what is happening. and their memory or occurs randomly during the day. CataplexyĬataplexy is a generally temporary disorder that causes a loss of muscle tone usually triggered by strong emotions such as crying, laughter, joy, etc. It can therefore be considered one of the many symptoms of catatonia, but it can also occur in patients who are NOT catatonic: a catatonic has catalepsy but someone who has catalepsy is not necessarily catatonic. It can also occur in completely healthy patients as a response to extreme traumatic shock. rigidity of the body, especially of the extremities (arms and legs) Ĭatalepsy (or ‘catalepsy’) is typically found in catatonia, in patients with schizophrenia and with manic-depressive neurosis.Ĭatalepsy is also observed in the symptom picture of Parkinson’s disease, epilepsy and certain sleep disorders, such as the ‘Gélineau syndrome’ in which catalepsy is associated with narcolepsy.Catalepsy is a condition characterised by psychomotor disturbances such as: In the course of catatonia, a tendency towards passivity can also manifest itself, reaching catalepsy. by refusing food, only to eat spontaneously when they see themselves alone, or by strenuously resisting body movements.Įven the stimuli of organic functions are actively resisted: the sick do not eat although they are hungry they forcibly withhold faeces and urine and so on. They react antagonistically (negativism) to the behaviour of those around them, e.g. uninterrupted repetition of sentences (‘broken record’). ![]() mutacism: difficulty on the part of the sufferer in pronouncing labial consonants.mannerism: the use of hyperbolic, overloaded and unnatural facial and body mimicry.stupor: lack of critical cognitive function combined with a level of consciousness that leads to the patient’s partial or total inability to respond to basic stimuli, such as pain.hypokinesia: marked decrease in movements.a catatonic could drink his own urine if asked to do so) automatic obedience to even nonsensical, absurd and/or humiliating commands (e.g.waxen flexibility: the possibility of forcing the subject to assume even uncomfortable physical positions for a certain period of time, as if they were wax statues.echolalia: the echoic repetition of the last words heard uttered by others.ecopraxia: the automatic imitation of acts that are seen to be performed.attitudes that are tiring to maintain over time, remaining in static ‘statue-like’ postures for a long time.During a cataplectic attack, there is a marked reduction in muscle tone similar to the normal physiologic hypotonia that accompanies rapid eye movement sleep (SLEEP, REM). Cataplexy is frequently associated with NARCOLEPSY. (Adams et al., Principles of Neurology, 6th ed, p396)Ī condition characterized by transient weakness or paralysis of somatic musculature triggered by an emotional stimulus or physical exertion. Durante un ataque cataléptico existe una acusada reducción del tono muscular similar a la hipotonía fisiológica normal que acompaña a los movimientos oculares rápidos del sueño (SUEÑO REM). La cataplejía se asocia con frecuencia con NARCOLEPSIA. Afección caracterizada por debilidad transitoria o parálisis de la musculatura somática que se desencadena por un estímulo emocional o por un esfuerzo físico.
