About Electroencephalogram
Key Highlights
-
Non-invasive and painless procedure with no radiation exposure.Provides real-time recording of brain's electrical activity.Essential tool for diagnosing epilepsy and seizure disorders.Helps evaluate brain function after injury or during sleep studies.Can assist in diagnosing conditions like encephalitis, tumors, or dementia.Safe for patients of all ages, including infants and children./ul
Who is this surgery for?
- Diagnosis and classification of epilepsy and seizure disorders.
- Evaluation of unexplained episodes of confusion, fainting, or memory loss.
- Assessment of brain function after a head injury, stroke, or brain infection.
- Diagnosis of sleep disorders like narcolepsy or sleep apnea.
- Monitoring brain activity during surgery or in critically ill patients.
- Evaluating suspected brain tumors, encephalitis, or degenerative diseases like dementia.
How to prepare
- Wash and dry hair thoroughly the night before; avoid using oils, gels, or sprays.
- Inform the neurologist about all medications, especially sedatives or anti-seizure drugs.
- Get adequate sleep the night before unless instructed otherwise for a sleep-deprived EEG.
- Avoid caffeine-containing products (coffee, tea, chocolate) for 8-12 hours prior.
- Eat a normal meal before the test to prevent low blood sugar, which can affect results.
- Bring a list of medications and any previous EEG reports if available.
Risks & possible complications
- Generally considered a very low-risk procedure with no significant complications.
- Minor skin irritation or redness at electrode sites, which resolves quickly.
- Rare allergic reaction to the electrode adhesive or gel.
- In rare cases, seizures may be intentionally provoked during the test for diagnosis.
- No risk of electric shock, as the electrodes only record activity and do not emit current.
Recovery & hospital stay
- No recovery time is needed; patients can resume normal activities immediately.
- Wash hair at home to remove any residual adhesive gel from the electrodes.
- Results are typically analyzed by a neurologist, with a follow-up appointment to discuss findings.
- No dietary or activity restrictions are required after the procedure.
- If sedatives were used, arrange for someone to drive you home.
-
Typical hospital stay: 0 days (outpatient procedure)
-
Expected recovery time: 0 days (immediate)

Reyansh Mehta is a 68-year-old retired...
Reyansh Mehta is a 68-year-old retired school principal from Mumbai, living with his daughter's family in the US. He has a history of well-controlled hypertension. For the past three months, he has experienced brief, unsettling episodes where he suddenly loses track of conversation, stares blankly for 10-15 seconds, and has a strange metallic taste in his mouth. His daughter noticed he sometimes smacks his lips during these spells. Concerned about a possible stroke or dementia, they visited a neurologist. The doctor, suspecting focal onset seizures, recommended an EEG to capture the brain's electrical activity and pinpoint any abnormal patterns. During the procedure, a technician gently measured Reyansh's head and attached small electrodes with paste. Reyansh was asked to breathe deeply and look at a flashing light, which felt strange but was not painful. He was relieved it was non-invasive. The EEG recorded several brief bursts of abnormal activity in his left temporal lobe, confirming a diagnosis of epilepsy. Reyansh was started on a low-dose anti-seizure medication. Emotionally, he moved from a place of fear and shame about 'losing his mind' to profound relief. Having a clear diagnosis and a treatable condition restored his sense of control and hope for an active retirement.
