Mar 8, 2024 · An EEG (electroencephalogram) is a safe, painless test that measures brain activity. Your healthcare provider may order an EEG to find out why you have certain symptoms like seizures, confusion or memory loss. They may use the term EEG to describe both the test (electroencephalography) and test results (electroencephalogram).

May 29, 2024 · An electroencephalogram (EEG) is a test that measures electrical activity in the brain. This test also is called an EEG. The test uses small, metal discs called electrodes that attach to the scalp. Brain cells communicate via electrical impulses, and this activity shows up as wavy lines on an EEG recording.

Nov 9, 2021 · An EEG is a test that measures your brain waves and helps detect abnormal brain activity. The results of an EEG can be used to rule out or confirm medical conditions.

Sep 6, 2024 · EEG technology measures changes in the brain that affect cognitive ability. Learn about neurological conditions and others diagnosed with EEG.

An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During an EEG, electrodes are pasted onto your scalp. These are small metal disks with thin wires. They detect tiny electrical charges that result from the activity of your brain cells.

Aug 3, 2020 · An EEG evaluates brain function by measuring the electrical activity within the brain. It records patterns of activity during rest and in response to certain stimuli. This helps your doctor diagnose and evaluate brain disorders and conditions.

Feb 25, 2025 · An electroencephalogram (EEG) detects abnormal brain waves that cause seizures. EEG uses include diagnosing epilepsy, sleep disorders, and brain tumors.

Dec 18, 2023 · An EEG, or electroencephalogram, is a test that records the electrical signals of the brain by using small metal discs (called electrodes) that are attached to your scalp. Your brain cells...

Jul 25, 2022 · An electroencephalogram (EEG) is a noninvasive, painless test that detects unusual electrical activity in the brain. A technician attaches electrodes to your scalp to record the electrical impulses that form brain wave activity. An EEG helps doctors diagnose or evaluate brain disorders and conditions.

An EEG test measures and monitors electricity in the brain to determine what is happening during a seizure or other event. There are two types of EEG: This 30-minute test is completed in the outpatient or inpatient setting.
