What kind of test is an EEG?

An EEG, or electroencephalogram, is specifically designed to measure electrical activity in the brain. This test records the brain's electrical signals through electrodes placed on the scalp, providing vital information about brain function. By analyzing these electrical impulses, healthcare professionals can diagnose various neurological conditions, such as epilepsy, sleep disorders, and other brain-related issues. The focus of an EEG is entirely on brain activity, making the option regarding brain wave testing the most accurate description of what an EEG entails.
