EEG
An electroencephalogram, or EEG, is a noninvasive test that records the brain’s electrical activity. It is commonly used to evaluate seizures, epilepsy, episodes of altered awareness, and other neurological symptoms.
At Hackensack Neurology, EEG testing helps provide important diagnostic information when brain wave activity needs to be studied more closely.
What Is an EEG?
An EEG uses small sensors placed on the scalp to measure electrical activity in the brain. The test can help identify abnormal brain wave patterns that may be associated with seizures or other neurological conditions.
Why an EEG May Be Recommended
- Evaluation of seizures or suspected epilepsy
- Episodes of staring, confusion, or loss of awareness
- Unexplained fainting or spells
- Assessment of abnormal movements
- Further neurological evaluation after certain symptoms or events
What to Expect During the Test
During an EEG, small electrodes are placed on the scalp to record brain wave activity. The test is painless and typically performed in an outpatient setting. In some cases, patients may be asked to breathe deeply or look at flashing lights during part of the study.
What the Results Can Show
- Abnormal electrical activity in the brain
- Patterns that may suggest seizures or epilepsy
- Normal or nonspecific findings that help guide further evaluation
Why This Test Matters
An EEG can provide critical information when evaluating episodes that may be neurological in origin. It helps your neurologist better understand what may be causing symptoms and whether additional testing or treatment is needed.
Schedule an Evaluation
If you have been referred for an EEG or are experiencing possible seizure-related symptoms, Hackensack Neurology offers expert neurological care supported by advanced diagnostic testing.
