1.The total stiffness – clonus attacks (unspecified)
It refers to the whole body muscle twitch and the attacks unconsciousness. It is common to occur after birth injury, brain injury, brain tumor, etc. The rigidity – clonus attacks can occur at any age, which is the most common type of attack of epilepsy. The typical attack can be divided into the aura period, tetanic period, clonus period and recovery period, four clinical stages. The electroencephalogram (EEG) during the attack is a typical explosive spike wave and spines – slow wave synthesis, each spine – slow wave synthesis are accompanied by muscle jumping.
2.Simple partial seizure
It indicates the corresponding symptoms responding to the functions of the certain areas, including motor, sensory, autonomic nervous and mental symptoms and related signs, which is caused by the local cerebral cortex discharge. It is divided into four groups:
(1) the patients with movement symptoms;
(2) the patients with body feeling or special feeling symptoms;
(3) the patients with autonomic nerve symptoms and relevant signs;
(4) the patients with mental symptoms.
3.The complex partial seizures
It is also called the psychomotor seizures, accompanied by disturbance of consciousness. The aura often occurs before loss of consciousness, or when it is about to lose, so patients can still recall after seizures.
4.Absence seizure (attack)
The typical characteristic is transient disturbance of consciousness, but not with aura or post attacks symptoms.
It refers to a single seizure of more than 30 minutes, or frequent epileptic seizures, which leads that the patient has not been a complete recovery while has another attack, total period is more than 30 minutes. Status epilepticus is a kind of emergency needing to be rescued.
