Performance 1: Generalized tonic-clonic seizure: grand mal seizure – Grand mal seizure, also called tonic-clonic seizure, is the most common type of seizure, accounting for about 81% of all seizures. Its performance: sudden loss of consciousness, eyes turned up, pupils dilated, teeth closed, incontinence, facial pallor or cyanosis, may have a pig’s cry (or sheep’s cry), followed by generalized tonic spasm, about a few minutes after the whole body convulsions stop naturally, spitting white foam or blood foam (when the tongue and oral mucosa bite broken), and finally muscle relaxation, the patient is comatose or drowsy, face gradually normal, and gradually awake. Expression 2: Anhedonic seizures:Each seizure lasts 2-15 seconds, not more than 1 minute, several to dozens of times a day. It occurs suddenly and ends suddenly. It is characterized by sudden interruption of speech and activity without falling, blank stare, occasional upturning, and sometimes pale face without aura. After the onset of a child’s petit mal seizure, the patient usually has no adverse reaction and can continue the original activity. Performance three: tonic seizures: sudden tonic contraction of the whole body muscles with loss of consciousness, so that the child is fixed in a certain position, but the duration is longer than myoclonus, about 5-60 seconds. It is common to see postures such as coracoacusis, neck extension, head tilt, head trunk rotation or mandatory mouth opening and eye opening. There are usually falls and postictal symptoms. Performance four: clonic seizures: rhythmic contraction of muscles throughout the body, often starting with the face, due to chewing muscle twitching, can bite the tongue and lips, gradually presenting subtle tremors in the extremities, the amplitude gradually increased and extended to the whole body, presenting intermittent flexion spasms, its frequency gradually decreases, lasting l to 3 minutes, and finally suddenly stop after a strong spasm, often accompanied by an accelerated heart rate, increased blood pressure, saliva During the seizure period, there is often an increase in heart rate, blood pressure, increased secretion of saliva and sweat, coarse breathing, foamy saliva coming out of the mouth, sometimes mixed with blood, and spitting of blood, dilated pupils, urinary incontinence, and even fecal incontinence. At this time, the pupil reflex and various deep and shallow reflexes are gone. The patient with myoclonic epilepsy may have a single twitch of the head, neck, limbs or trunk muscles, sometimes only one muscle or some muscle groups. The jerk is immediately followed by relaxation, either on one side or on both sides. Mild myoclonus affects only the head or hands. The upper extremity twitches can cause objects to be lost or thrown from the hand. In more severe cases, the whole body is affected, and the person suddenly loses balance and falls when standing. When sitting, it can jump out from where it is sitting. Therefore, such patients are often scarred on the forehead, tip of the nose, and lips of the mouth. Usually there are individual seizures once or several repeated seizures within a few seconds, more seizures when sleeping or just waking up, or even a continuous state. Myoclonic seizures are often followed by one jerk, a few seconds apart, and then several consecutive jerks. It is most likely to occur when you are about to sleep or wake up. Performance 6: Atonic seizures: Atonic seizures in epilepsy are characterized by a sudden decrease or loss of generalized muscle tone, resulting in a sudden fall. A brief atonic seizure lasts only about 1 second, and the loss of consciousness is often not obvious. An atonic seizure can last from one to several minutes, or a prolonged seizure in which the patient lies limp, stares or closes his eyes, and has no vocal or motor symptoms. Atonic seizures can be characterized by repeated and continuous dystonic falls, or prolonged loss of consciousness with loss of generalized muscle tone. Performance seven: spastic seizures: this seizure is most common in infantile spasms, manifested by the simultaneous appearance of nodding, arm extension (or elbow flexion), bending, kicking (or leg flexion) or overextension-like movements, the entire process of muscle contraction about 1 to 3 seconds, the speed of muscle contraction is slower than myoclonic seizures, longer duration, but shorter than tonic seizures. Performance 8: Complex partial seizures: seen in temporal lobe epilepsy and partial frontal lobe epilepsy, with varying degrees of impaired consciousness, often with psychiatric symptoms, often with repetitive stereotyped automatisms. Such as swallowing, chewing, lip licking, hand clapping, groping, and self-talk. Manifestation IX: Autonomic symptomatic seizures: such as epigastric discomfort, vomiting, pallor, flushing, sweating, vertical hair, dilated pupils, bowel sounds or urinary incontinence, etc. Manifestation X: Psychotic symptomatic seizures: may manifest as hallucinations, delusions, memory impairment, cognitive impairment, emotional impairment or language impairment, etc.
