See also:CATALEPSY (from Gr. KarItNtA is, a seizure) , a See also:term applied to a See also:nervous See also:affection characterized by the sudden suspension of sensation and volition, accompanied with a See also:peculiar rigidity of the whole or of certain muscles of the See also:body . The subjects of See also:catalepsy are in most instances See also:females of highly nervous temperament . The exciting cause of an attack is usually See also:mental emotion operating either suddenly, as in the See also:case of a fright, or more gradually in the way of prolonged depression . The symptoms presented vary in different cases, and even in the same individual in different attacks . Sometimes the typical features of the disease are exhibited in a See also:state of See also:complete insensibility, together with a statue-like See also:appearance of the body which will retain any attitude it may be made to assume during the continuance of the attack . In this See also:condition the whole organic and vital functions appear to be reduced to the lowest possible limit consistent with See also:life, and to such a degree as to simulate actual See also:death . At other times considerable mental excitement will accompany the cataleptic symptoms, and the patient will sing or utter passionate exclamations during the See also:fit, being all the while quite unconscious . The attack may be of See also:short duration, passing off within a few minutes . It may, however, last for many See also:hours, and in some rare instances persist for several days; and it is conceivable that in such cases the appearances presented might be mistaken for real death, as is alleged to have occasion-ally happened . Catalepsy belongs to the class of functional nervous disorders (see MUSCLE AND See also:NERVE: See also:Pathology) in which morbid See also:physical and psychical conditions are mixed up . Al-though it is said to occur in persons in perfect See also:health, careful inquiry will usually reveal some departure from the normal state, as is shown by the greater number of the recorded cases . More particularly is this true of females, in whom some See also:form of menstrual derangement is generally found to have preceded the cataleptic affection . Catalepsy is sometimes associated with See also:epilepsy and with See also:grave forms of mental disease . In See also:ordinary cases, however, the mental phenomena See also:bear See also:close resemblance to those witnessed in See also:hysteria . In many of the subjects of catalepsy there appears to be a remarkable weakness of the will, whereby the tendency to See also:lapse into the cataleptic state is not resisted but rather in some measure encouraged, and attacks may thus be induced by the most trivial circumstances . |
