Hysteria isn't that frightening.
It's a cognitive disorder of the central nervous system often caused by intense emotions like extreme joy or sorrow, major life events, or suggestion and autosuggestion.
This condition can generally be treated effectively with subsequent psychological counseling and therapy, leading to a good recovery.
A well-known example is the character Fan Jin from a famous Chinese story. His descent into madness after learning he'd passed the imperial examinations is a classic case of a hysterical episode.
It wasn't too surprising that the child, after being frightened last night, woke up this morning with hysteria.
But epilepsy is an entirely different matter. It's an extremely tricky condition.
It's a chronic disease where sudden, abnormal electrical discharges from brain neurons cause temporary cerebral dysfunction.
