Ett tillstånd kännetecknat av övergående muskelsvaghet eller -förlamning som följd av en känslomässig reaktion eller fysisk utmattning. Kataplexi hänger ofta samman med narkolepsi. I samband med ett k ataplektiskt anfall ses en minskad muskelspänning, liknande den normala fysiologiska hypotonin vid REM-sömn.
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).
