There are many forms of clinical seizures in epilepsy, the common ones are as follows: a. Generalized tonic: clonic seizures, also known as grand mal seizures. According to the development process, they are divided into: 1. Aura phase: about half of the patients have aura, which refers to various experiences that occur in the moment before loss of consciousness. The common aura can be special sensory hallucinations, phantom smells, vertigo, general sensory limb numbness and electric sensation. 2, spastic phase: following the aura phase, followed by loss of consciousness, enter the spasmodic seizure phase. The first is the tonic seizure (tonic phase), showing a sudden scream, fall to the ground, the whole body muscle tonic, upper limbs straight or flexed, hands clenched fist, lower limbs straight, head turned to the side or backward, eyes gazing upward, lasting about a minute. 3. Sleepy period: After the convulsions stop, the patient enters a drowsy, comatose state, and then gradually wakes up. Some patients have abnormal mental behavior during the waking process, manifesting as struggling, refusal, restlessness. Second, loss of consciousness seizures: also known as petit mal seizures. There are usually the following types: 1. Simple aphasic seizures: also known as typical aphasic seizures. The clinical phenotype is a sudden onset and stoppage of consciousness, which can occur in the context of work, activity, eating and walking. 2.Complex aphasic seizures: also known as aphasic seizure automatism. In addition to episodic loss of consciousness, there may be some manifestations similar to temporal lobe automatism during the seizure, such as smacking, aimless groping, rubbing hands together, wandering and some other trigger actions. 3, myoclonic aphasic seizures: also known as myoclonic seizures. It is a brief myoclonic seizure of the eyes, face, neck, extremities or trunk, without or with a brief impairment of consciousness. 4, motor inability seizure: also known as loss of tension sudden collapse seizure. Sudden onset of transient impairment of consciousness, loss of muscle tone and posture cannot be maintained and fall down. The EEG performance is the same as that of simple aphasic seizures. Simple partial seizures: also known as limited seizures, are episodes of motor, sensory and vegetative symptoms without consciousness impairment. Complex partial seizures: also known as psychomotor seizures, are partial seizures with impaired consciousness, and most of them are in the temporal lobe, so they are also called temporal lobe seizures.
