|
|---|---|
| Definition (NCI) | A rare disorder characterized by sudden and transient episodes of loss of muscle tone. It often follows an experience of intense emotions. It is seen in patients with narcolepsy. |
| Definition (CSP) | transient attack of weakness precipitated by emotional excitement; patient falls as if struck down. |
| Definition (MSH) | A condition characterized by transient weakness or paralysis of somatic musculature triggered by an emotional stimulus or physical exertion. Cataplexy is frequently associated with NARCOLEPSY. 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). (From Adams et al., Principles of Neurology, 6th ed, p396) |
| Definition (PSY) | Temporary loss of muscle tone or weakness following extreme emotion. |
