Long-Term Video EEG Monitoring - VEM
Long-term video EEG monitoring (VEM) is a method in which EEG recording is performed continuously for hours or days, accompanied by detailed and clear video monitoring of the patient's behaviors. The typical complaint described by the patient is observed on video while simultaneously documenting the brain's electrical activity. In epileptic patients, epilepsy classification is performed and the most appropriate treatment is selected. VEM is an indispensable investigation, particularly for patients with refractory epilepsy who are surgical candidates.

By evaluating seizure semiology, the brain region from which the seizure originates is identified, enabling surgical resection of that region. Additionally, many disorders in the differential diagnosis of epilepsy can be differentiated. Simultaneous monitoring of the video image and brain waves determines whether the complaint is an epileptic seizure, a sleep behavior disorder, or a non-epileptic psychogenic disorder. Since ECG recording is also obtained from patients, cardiac arrhythmias that can be confused with epileptic seizures are detected. Differentiating between epileptic and non-epileptic patients helps resolve cases of patients who have used medication unnecessarily for years and could not find a solution because they did not actually have epilepsy.
Long-term Video EEG Monitoring is an evaluation method performed at select centers in Turkey, particularly in Ankara.
