Pronunciation: ih-lek-troh-en-SEFF-uh-loh-gram
A diagnostic test that records electrical activity in the brain using electrodes placed on the scalp.
Full Definition
An electroencephalogram (EEG) is a non-invasive neurological test that measures and records the electrical activity of the brain through electrodes attached to the scalp. The test produces wave patterns that help diagnose conditions such as epilepsy, sleep disorders, brain tumors, and other neurological conditions. EEGs are commonly referenced in clinical neuroscience documentation and patient records.
Usage
Usage note: Often abbreviated as EEG in clinical contexts. Do not confuse with other electro- diagnostic tests.
In Context
- "The patient's electroencephalogram showed abnormal spike-and-wave patterns consistent with temporal lobe epilepsy." — Clinical report
