Convulsions are one of the common pediatric emergencies and manifest as sudden onset of generalized or localized muscle twitching, eyes rolling upward or squinting, or frequent blinking, pale or cyanotic face and lips, closed teeth, foaming at the mouth, and stiff or rhythmic twitching of the extremities. The symptomatic manifestations of sleep twitching are related to the etiology. Sleep twitches are classified as physiological and pathological. Physiological sleep twitching is a kind of rapid involuntary muscle twitching, and the body involuntarily “shakes” when falling asleep, and this phenomenon is called sleep twitching, which is a kind of general muscle twitching not controlled by will. Pathological twitching in sleep is related to the primary disease. There are many causes of convulsions, including high fever, epilepsy, intracranial infection, intracranial occupying lesions, brain developmental malformations, brain injury, cerebral hemorrhage, electrolyte disorders such as hypoglycemia and hypomagnesemia, and toxic encephalopathy. Convulsive seizures are divided into partial seizures (limited convulsions in any part of the body), generalized seizures: tonic-clonic seizures (grand mal seizures), tonic seizures, and clonic seizures. Grand mal seizures are characterized by continuous contraction of the bony iliac muscles throughout the body, apnea, foaming at the mouth, and twitching of the limbs, possibly accompanied by tongue bite and urinary incontinence. It lasts 1 to 5 minutes and falls asleep after the twitching stops. On awakening, there is headache and weakness, and there is no memory of the seizure. Children with myoclonic seizures exhibit sudden, forceful, rapid jerking of a muscle or group of muscles, some localized and some may cause twitching of one or both limbs. Parents can record a complete video for the doctor to understand the symptoms of seizures, and if necessary, perform cranial MRI, EEG and blood tests to clarify the cause and provide timely treatment.
