EEG

What is an EEG Test Procedure?

The EEG test procedure measures tiny electrical signals produced by your brain's nerve cells using small metal discs called electrodes placed on your scalp. These signals appear as wavy lines on a computer screen, helping doctors identify abnormal patterns that might indicate seizures or other brain issues. It's completely painless and typically takes 30 to 60 minutes, making it a quick way to gain valuable insights into brain function.

A simple explanation for patients

Think of an EEG as taking a picture of your brain's electrical chatter. Electrodes on your head pick up these signals like tiny microphones, showing doctors if everything is working normally or if there are any unusual patterns.

Why is an EEG Procedure Needed?

Doctors recommend an EEG when you experience unexplained seizures, confusion, memory problems, or sleep disturbances. It helps pinpoint epilepsy, evaluate brain injuries, or monitor conditions like dementia. Early detection through EEG can lead to better treatment plans and improved quality of life.

Common Reasons and Conditions Evaluated

• Suspected epilepsy or seizure disorders.
• Evaluation of unexplained fainting or confusion.
• Monitoring brain activity during sleep disorders.
• Assessment after head injury or stroke.
• Checking the effectiveness of seizure medications.

Different Types of EEG

Several types of EEG exist to capture brain activity under various conditions. Routine EEGs are standard for quick assessments, while others provide deeper insights for complex cases.

• Routine EEG: 20-40 minutes of recording while awake and relaxed.
• Sleep EEG: Captures brain waves during natural or induced sleep.
• Ambulatory EEG: Portable device worn for 24-72 hours at home.
• Video EEG: Combines EEG with video to correlate behaviour with brain activity.
• Invasive EEG: Electrodes placed inside the skull for precise localisation.

Indications for EEG Test Procedure

Candidates include anyone with symptoms suggesting abnormal brain electrical activity, from children with first seizures to adults with cognitive changes.

• First-time seizures or recurrent episodes.
• Spells of staring, confusion, or unusual behaviours.
• Sleep problems affecting daytime function.
• Follow-up for epilepsy treatment effectiveness.
• Pre-surgical evaluation for epilepsy surgery candidates.

Who Should Avoid or Delay Types of EEG?

EEG is safe for nearly everyone, but certain situations require precautions.

• Scalp infections or open wounds at electrode sites.
• Severe anxiety about the procedure (sedation available).
• Recent hair treatments are affecting electrode adhesion.

Preparing for EEG Procedure

• Wash hair thoroughly; avoid gels, sprays, or oils.
• Avoid caffeine for 8 hours before a routine EEG.
• Bring a list of current medications and medical history.
• Plan for sleep deprivation if a sleep EEG is requested.
• Arrange transport if sedation will be used.
• Wear comfortable clothing for extended monitoring.

What Will Happen During the EEG Test Procedure?

You'll relax in a comfortable reclining chair while a technician gently measures your head and applies electrodes using a mild abrasive paste for clear signals. The room stays quiet and dimly lit as the recording begins, with occasional tasks like deep breathing or watching flashing lights to provoke brain responses.

Step-by-Step Breakdown

• The technician measures the head and marks 16-25 electrode positions.
• Skin is prepped with abrasive cream, and conductive gel is applied.
• Electrodes secured with paste or cap; impedance checked.
• Recording starts; eyes open/close, hyperventilation, photic stimulation.
• Sleep recording if needed; video monitoring for behaviour correlation.
• Session ends; electrodes removed easily with warm water.

Recovery After EEG Procedure

No recovery needed; resume normal activities immediately unless sedated. Some gel residue washes out easily at home. Results discussed within days, guiding next treatment steps.

Risks & Complications

Extremely safe with no radiation. Rare minor skin irritation from the paste resolves quickly. Sedation risks are minimal when used appropriately.

Benefits of Types of EEG

Provides crucial diagnostic information without surgery, guides medication choices, monitors treatment, and localises seizure foci precisely.
