What is EEG ?

Electroencephalography (EEG) is a non-invasive medical test that measures electrical activity in the brain. It involves placing small electrodes on the scalp, which detect and record the brain’s electrical signals. These signals are displayed as wavy lines on an EEG recording, known as an electroencephalogram.

EEG is used for various purposes, including:

– Diagnosing and monitoring epilepsy and other seizure disorders

– Investigating causes of unexplained periods of unconsciousness

– Diagnosing sleep disorders

– Evaluating brain function in cases of coma or brain injury

– Monitoring brain activity during surgery

The procedure is safe and typically painless, although some people may find the electrodes slightly uncomfortable. It provides valuable information about brain activity and can help guide treatment decisions for various neurological conditions.
