If your baby has a sudden convulsion and rolls his eyes, consider it a convulsive seizure. First of all, let the child be quiet, and try to take the lateral position of the head to prevent suffocation due to convulsions. After the convulsions stop, the child should be sent to the pediatric department of the nearest hospital as soon as possible, and the head MRI, 24-hour EEG and blood tests are needed to clarify the cause of the convulsions. If there is a fever, the possibility of febrile convulsions, viral encephalitis and septic meningitis is more likely.
