How long is an eeg test

An electroencephalogram—or EEG for short—is a diagnostic test that looks at the electrical activity in your brain. An EEG is often used to detect and evaluate epilepsy (a condition that causes frequent seizures), but may also be helpful for other conditions like brain injuries or sleep disorders.

During an EEG, your healthcare provider will attach wires and electrodes to your scalp that transmits information and brain activity to a computer.

Abnormal eeg results

Generally, a neurologist (or, a doctor who specializes in the brain and spinal cord) will order the test and review the results.

Purpose

An EEG looks at the electrical activity in the brain. A neurologist interprets EEGs and looks at patterns of brainwave activity to diagnose any potential brain abnormalities.

EEGs are most often used to evaluate and monitor seizure disorders, like epilepsy. However, your provider may also order an EEG to assess your risk or look for symptoms for the following conditions:

• Stroke
• Concussion
• Dementia
• Sleep disorders
• Syncope (loss of consciousness)
• Brain tum
