![]() ![]() Some of these issues can be treated with epilepsy surgery. ![]() Some seizures and epilepsies are due to irregularities within the brain tissue, such as scars, tumors or other lesions that can show up on radiologic imaging. Prolonged video-EEG monitoring uses a video camera to capture onset and characteristics of seizures simultaneously with an EEG. Prolonged EEGs: If a routine EEG is normal, diagnosing seizures may require a stay in an epilepsy monitoring unit for continuous EEG monitoring with video over several days. Clinicians can find evidence of abnormal electrical activity in the brain and figure out the type or types of seizures a patient is having, as well as the origin(s), by measuring brain waves over minutes to a couple of hours. These studies are interpreted, or “read,” by a trained neurologist. Routine EEG: Monitoring of electrical signals in the brain with electrodes (sensors) attached to the scalp is usually first performed in a specialized outpatient clinic. ![]()
