EEG is done in infants when there are brain infections, trauma, and hypoxia. When infants have brain infections, trauma, hypoxia, poisoning and brain damage, twitching disorders, etc., they need to know about the EEG and have it done to aid in diagnosis. When epilepsy is suspected, EEG is needed to facilitate the diagnosis of the type of epilepsy and the observation of the efficacy after treatment. EEG is also useful for the detection of intracranial tumors, brain abscesses, viral encephalitis, septic cerebrospinal meningitis and other diseases.
