Overview & Description
Electroencephalography (EEG) is a non-invasive diagnostic test that measures and records the electrical activity of the brain. Electrodes are carefully placed on the scalp to detect electrical signals produced by brain cells. The resulting waveforms provide critical information about brain function and help our neurologists identify abnormalities.
Purpose & Uses
Types of EEG Procedures
Routine EEG
A standard 20-30 minute recording performed while the patient is at rest in a comfortable environment.
Sleep EEG
Recording conducted during sleep to capture specific sleep-related neurological abnormalities.
Ambulatory EEG
A portable 24-48 hour recording designed to detect intermittent abnormalities over a longer period.
Video EEG Monitoring
Simultaneous video and EEG recording to accurately capture seizures and correlate them with clinical events.
Understanding Your Results
Normal EEG: Indicates regular, organized electrical activity in the brain.
Abnormal EEG: Reveals irregular patterns, spikes, or slowing that may indicate seizures, tumors, or other underlying conditions.
Note: All results are thoroughly interpreted by our board-certified neurologists and discussed in detail with the patient during a follow-up consultation.
Preparation Checklist
- ✓ Wash hair the night before (no conditioner, oils, or styling products)
- ✓ Avoid caffeine 12 hours before the test
- ✓ Get adequate sleep the night before
- ✓ Eat a light meal before the test (low blood sugar affects results)
- ✓ Wear comfortable, loose clothing
- ✓ Bring a list of current medications
Procedure Steps
Step 1: Positioning
Patient sits or lies down in a comfortable position.
Step 2: Electrode Placement
Electrodes are carefully placed on the scalp using a special conductive paste.
Step 3: Recording Begins
Patient is asked to relax with eyes closed while brain activity is recorded for 20-30 mins.
Step 4: Stimulation (Optional)
Various harmless stimuli (flashing lights or sounds) may be presented to check reactions.
Step 5: Completion
Electrodes are removed and the scalp is thoroughly cleaned.
