Name of the Procedure:

Electroencephalogram with video (VEEG), review of data, technical description by EEG technologist, each increment of 12-26 hours; unmonitored

Summary

A Video Electroencephalogram (VEEG) is a diagnostic procedure that records electrical activity in the brain while also capturing video footage. This allows for a comprehensive review of both brain electrical patterns and physical behavior, aiding in the diagnosis of neurological conditions. The data is recorded over a 12-26 hour period and reviewed later by a qualified EEG technologist.

Purpose

The VEEG procedure is primarily used to diagnose and monitor seizure disorders, unexplained episodes, or other neurological conditions. Its main goal is to correlate brain electrical activity with physical behaviors or events to assist in formulating a precise diagnosis and treatment plan.

Indications

• Unexplained seizures or episodes
• Suspected epilepsy
• Monitoring of known seizure disorders
• Assessment of unexplained neurological symptoms

Preparation

• Patients may be asked to wash their hair and refrain from using hair products before the test.
• Instructions may include continuing, adjusting, or stopping certain medications.
• Patients might be asked to stay awake for part of the night before the procedure to increase the likelihood of recording seizure activity.

Procedure Description

1. Electrode Placement: Small, flat metal discs (electrodes) are placed on the scalp using a special adhesive.
2. Video Recording Setup: A camera is positioned to record the patient’s movements and behaviors during the procedure.
3. Data Recording: The EEG equipment records the brain's electrical activity continuously over 12-26 hours.
4. Monitoring: Although the procedure is unmonitored, the data is stored for later review.
5. Technologist Review: An experienced EEG technologist reviews the recorded data and video footage to identify any abnormal activity.

Duration

The VEEG procedure typically requires continuous data collection over a period of 12 to 26 hours.

Setting

The procedure is performed in a controlled medical environment such as a hospital or specialized outpatient clinic equipped with EEG and video recording technology.

Personnel

• EEG Technologists: Responsible for setting up the equipment, placing electrodes, and later reviewing the data.
• Neurologists: May provide oversight and interpret the findings.

Risks and Complications

• Skin irritation or discomfort from the electrodes.
• Rare risk of allergic reactions to adhesive materials.
• In very rare cases, during the recording period, a seizure might occur, requiring immediate medical attention.

Benefits

• Provides a comprehensive correlation between brain electrical activity and physical behavior.
• Helps in accurate diagnosis and treatment planning for seizure disorders.
• Non-invasive and highly detailed diagnostic method.

Recovery

• No specific recovery time; normal activities can be resumed immediately after the procedure.
• Patients may need to remove any remaining adhesive from their scalp.
• Follow-up appointments may be scheduled to discuss the results with a neurologist.

Alternatives

• Standard EEG without video monitoring, which is less comprehensive.
• Ambulatory EEG that allows patients to go home with the recording device.
• Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scans, which provide structural images but not electrical activity.

Patient Experience

During the procedure, patients can move around and engage in normal activities within the monitored area. They might feel some initial discomfort due to the electrodes and adhesive. Post-procedure, there should be minimal to no physical discomfort, and normal activities can be resumed promptly. Pain or discomfort is generally not associated with this procedure.
