Question
A 4-year-old and 3-month-old child is unable to walk independently, can only crawl, cannot speak, and cannot recognize people. On the 7th day of life, a severe neonatal jaundice was discovered with a bilirubin index of 490, fever of 37.5 degrees Celsius. The child was hospitalized for blue light treatment without blood transfusion. The jaundice subsided three days later. At 20 months old, the child underwent four sessions of pediatric rehabilitation therapy, but the effects were not significant, and the treatment was stopped. Magnetic resonance imaging revealed an imbalance in the ratio of white matter to gray matter in the brain. Epilepsy appeared at the age of 2.5 years, with each seizure lasting a few seconds and occurring 2 to 3 times every 2 to 3 months. The child received some treatment. In the past two months, the seizures have become particularly severe, and sodium valproate, an antiepileptic drug, has been started. However, seizures still occur; is it necessary to switch to other antiepileptic medications?
