According to the seizure situation can be mainly divided into grand mal, petit mal, psychomotor seizure, restrictive seizure and complex partial seizure. 1, grand mal seizures, also known as generalized seizures, half of them have aura, such as dizziness, confusion, epigastric discomfort, visual and auditory and olfactory impairment. During the seizure (spasmodic seizure), some patients first make a sharp cry, then both lose consciousness and fall, there is a general muscle tonic, respiratory arrest, head and eyes can be deviated to one side, a few seconds later there is a clonic jerk, jerk gradually aggravated, lasting several seconds, the clonic period breathing recovery, foaming at the mouth (such as tongue was bitten to appear blood foam). Some patients have urinary and fecal incontinence, general relaxation after convulsions or go into lethargy (lethargic phase), after which consciousness gradually returns. 2. Petit mal seizures, which can be brief (2 to 15 seconds) with impaired consciousness or loss of consciousness without generalized spasms. There may be multiple seizures per day, sometimes with rhythmic blinking, head bowing, straightening of the eyes, and upper limb twitching. 3. Psychomotor seizures can be characterized by sudden onset, blurred consciousness, irregular and uncoordinated movements (e.g., sucking, chewing, searching, shouting, running, struggling, etc.). The patient’s movements are unmotivated, aimless, blind, and impulsive, and the seizures last for hours or sometimes days. The patient has no memory of the seizure. 4. Restricted seizures are usually seen in patients with organic damage to the cerebral cortex and are characterized by episodic twitching or sensory abnormalities in one corner of the mouth, fingers or toes, which may spread to one side of the body. When the seizure involves both sides of the body, it can be manifested as a grand mal seizure. 5, complex partial seizures, subtype of seizures with impaired consciousness, can not recall the seizure, can also be manifested as gaze and automatic symptoms such as smacking, chewing, groping, wandering, fiddling, humming, mumbling or other symptoms and signs.
