Epilepsy is caused by abnormal discharges of neurons in the brain, and the main manifestations of epilepsy in three-year-old children are convulsions, muscle twitching and cognitive impairment. Children’s cerebral cortical function is not yet fully developed, prone to strong brain excitation, which leads to abnormal discharges of nerve cells in the brain, the child suddenly develops convulsions, muscle convulsions and even cognitive disorders, and long-term, frequent episodes of abnormal discharges can lead to brain damage and even persistent neuropsychiatric disorders. Epilepsy is a common neurological disease in childhood, with an overall prevalence of 16/100,000 to 51/100,000 in China. If epilepsy is not treated and controlled in a timely and standardized manner, it will seriously affect the growth and development, physical and mental health of the affected children, sap their will, and strike their self-esteem, causing some irreversible damage. When parents find that their children have epilepsy symptoms, it is recommended that they consult a doctor in time.
