Slow wave paroxysm is a kind of waveform in EEG, which can be seen in epilepsy, intracranial infection and other neurological diseases, and needs to be analyzed in combination with symptoms, signs and other auxiliary examinations. If the patient has symptoms of convulsive and spasmodic seizures, and the EEG shows slow wave paroxysm, it is necessary to be alert to the possibility of epilepsy, and the diagnosis can be clarified by improving the cranial MR and dynamic EEG. If the EEG suggests slow wave paroxysm accompanied by fever, nausea and vomiting, headache and dizziness, intracranial infection should be excluded, and lumbar puncture can be perfected to obtain cerebrospinal fluid and send it for examination to assist in the identification. If the EEG indicates slow wave bursts, it is recommended to consult a specialist in the hospital as soon as possible to check for neurological disorders to avoid delaying the condition.
