EEG (Electroencephalogram)

What is an EEG (Electroencephalogram)?

An EEG (Electroencephalogram) is a safe, painless test that records the brain's electrical activity using small metal discs (electrodes) placed on the scalp. The test reveals brain wave patterns and helps diagnose various neurological conditions including epilepsy, sleep disorders, brain injuries, and other abnormalities by detecting abnormal electrical signals. EEG is an essential diagnostic tool in neurology for evaluating brain function and detecting seizure disorders.

EEG Services We Offer

Routine EEG: Standard 20-30 minute recording of brain electrical activity while patient is awake and at rest. Most commonly performed to evaluate seizures, encephalopathy, and baseline brain function. Includes activation procedures like hyperventilation and photic stimulation.

Seizure Disorder Evaluation: Specialized EEG monitoring to detect seizure activity, identify seizure focus, and classify seizure types for proper management and treatment planning.

Sleep Study EEG: Extended monitoring during sleep to evaluate sleep disorders, parasomnias, and detect abnormal brain activity during sleep cycles.

Prolonged/Continuous EEG Monitoring: 24-48 hour or longer recordings in ICU or specialized unit for critically ill patients or those with frequent seizures.

Ambulatory EEG: Portable EEG monitoring system worn at home or in natural environment for extended recordings during daily activities.

Conditions Detected by EEG

• Epilepsy and Seizure Disorders
• Sleep Disorders (Sleep Apnea, Narcolepsy, REM Sleep Behavior Disorder)
• Brain Injuries and Head Trauma
• Encephalitis (Brain Inflammation)
• Dementia and Neurodegenerative Disorders
• Coma Assessment
• Brain Tumors
• Behavioral and Psychiatric Disorders
• Loss of Consciousness Assessment

What to Expect During Your EEG

• You will sit comfortably in a reclined chair or lie on an examination bed
• Small metal discs (electrodes) are attached to your scalp with conductive paste or glue
• The placement follows a standard 10-20 system for consistent electrode positioning
• Electrodes are connected to the EEG machine via wires
• You remain calm and still while the machine records brain activity
• You may be asked to open and close your eyes, breathe deeply, or watch a flickering light
• The test is painless and typically takes 30-60 minutes
• After testing, conductive paste is easily washed out with water
• Results are analyzed and interpreted by neurologists

Preparation Guidelines

• Wash your hair the night before the test (avoid conditioner and hair products)
• Wear comfortable, easy-to-remove clothing
• Avoid caffeine for 12 hours before the test if possible
• Get adequate sleep before the test (or deprivation as instructed)
• Inform us of all current medications, especially anti-seizure drugs
• Bring a list of current symptoms and medical history
• Inform staff if you have any metal implants or pacemakers
• Arrive 15 minutes early for registration and instructions
• Have a light meal 2-3 hours before the test

Advanced Features of Our EEG Services

Multi-Channel Recording: Our advanced EEG systems use 16-32+ channels with high sampling rates for precise brain activity mapping and detection of subtle abnormalities.

Digital Signal Processing: Advanced noise filtering and artifact removal techniques ensure clean, interpretable recordings with minimal interference.

Expert Neurologist Interpretation: Our specialized neurologists provide comprehensive analysis including visual interpretation, quantitative analysis, and clinical correlation.

Secure Digital Archive: All EEG recordings and reports are securely stored for easy access, comparison with previous studies, and telemedicine consultation.

Activation Procedures: We routinely perform hyperventilation and photic stimulation to provoke abnormal activity and increase diagnostic yield.
