Question
A three-and-a-half-year-old child is experiencing symptoms of drooling and vomiting foam, but no seizures have been observed. After consulting a doctor in Shanghai, it was indicated that the condition is hopeful for recovery, but for over a year, the child has continued to vomit foam, and the family is urgently seeking a solution.
Answer
Epilepsy is a chronic disease caused by abnormal discharge of brain neurons, characterized by recurrent episodes of symptoms, including sudden collapse, vomiting foam, clenched jaws, limb spasms, and confusion. Frequent vomiting foam is considered a symptom of simple partial seizures. The diagnosis of epilepsy usually depends on clinical symptoms and evidence of epileptic discharges found in electroencephalograms (EEGs). It is recommended to undergo EEG examination at a regular medical institution and to seek treatment as soon as possible.
