Adolescent catatonic epilepsy presents as a brief sudden loss of consciousness, which may be accompanied by paroxysmal muscle spasms or automatisms, with each seizure lasting 5 to 30 seconds. The disease develops in adolescence and there is no difference between males and females. 1. Transient loss of consciousness: without any signs, it manifests as a sudden stop of the ongoing activities, loss of consciousness for a short period of time, staring with both eyes, which can be maintained for tens of seconds, and no memory of what has just happened when the self regains consciousness. 2. Paroxysmal myoclonic spasms: Rhythmic, repeated and rapid contractions of the muscles, manifested by involuntary jerking of the body. 3. Automatisms: Although in an unconscious state, involuntary simple or complex movements, such as nodding and chewing, occur. If you have any of the above symptoms, please take further treatment or therapy under the guidance of your doctor.
