What is VEEG: An Ambulatory EEG (Amb EEG) is a safe, painless test, which will record the electrical activity produced by your brain. An Amb EEG uses a digital recording system to record brain activity for 24-72 hours while you go about your daily routine.
Why we do VEEG: Seizure Disorders and Epilepsy. Abnormal electrical activity in the brain can cause seizures. When a person has repeated seizures, this condition is called epilepsy. Diagnosis and treatment of these disorders often requires EEG / VEEG test and consultation with a neurologist.
EEG vs. VEEG: In order to diagnose patients properly with Seizure Disorder or Epilepsy, doctor would need to conduct EEG test. During this test patient must fall asleep. However, around 30% of patients are never able to do that. Hence, prolonged (24-72 hours) EEG study a.k.a. "ambulatory EEG" or "VEEG" is recommended.
