It is generally prone to onset in adolescence, far more in females than males, without obvious organic lesions, and is clearly distinguishable from diseases such as epilepsy. It generally occurs easily during major life events, such as family discord, emotional agitation, such as personality humiliation, suggestion or self-referral, and can manifest as convulsions, cramps, sudden physical paralysis, inability to move, or memory loss, as well as loud shouting, moodiness, breathing difficulties, and blindness. In this case, treatment is mainly based on psychological counseling, emotional relief, etc., but also appropriate oral small doses of anti-psychotic drugs, and serious cases can be treated by psychological intervention in a timely manner by consulting a psychological specialist.
