Video-EEG monitoring with daytime recording - 4 hours
Electroencephalography (EEG) is a method used to record the brain’s electrical activity, allowing for the assessment of the functional state of various areas of the cerebral cortex and deeper brain structures. 4-hour EEG monitoring is performed to detect potential abnormalities in the brain's bioelectrical activity, such as epileptic seizures, sleep disorders, and other neurological conditions.
EEG Monitoring Procedure
During the procedure, a special cap or mesh fitted with multiple electrodes is placed on the patient's head to record electrical activity from different brain regions. The data collected is then analyzed by a neurophysiology specialist to identify any deviations from normal patterns.
EEG monitoring is a safe and non-invasive procedure that provides valuable insights into brain function and assists in diagnosing various neurological disorders.
Role of 4-Hour EEG Monitoring
4-hour EEG monitoring is an important diagnostic method that allows for extended evaluation of brain activity and identification of potential abnormalities. This extended observation enables the detection of changes in electrical brain activity over a longer period, which can support the diagnosis of various neurological disorders such as epilepsy, sleep disturbances, brain injuries, and more.
Indications for 4-Hour EEG Monitoring
4-hour EEG monitoring may be recommended in the following situations:
- Suspected epilepsy or other seizure disorders:Prolonged EEG recording allows for the detection of epileptic activity and helps diagnose various forms of epilepsy.
- Assessment after traumatic brain injury:EEG monitoring may help detect abnormalities in brain activity and monitor recovery progress following head trauma.
- Evaluation of sleep disorders:EEG monitoring is used to diagnose various sleep disorders, including sleep apnea, insomnia, and others.
- Neurological disease monitoring:Prolonged EEG recording can help evaluate brain activity in cases such as Alzheimer’s disease, Parkinson’s disease, and other neurological conditions.
Preparation for the EEG Procedure
No special preparation is required for 4-hour EEG monitoring. However, the following guidelines are recommended:
- Avoid caffeine-containing beverages (coffee, energy drinks) a few hours before the procedure, as they may influence the results.
- Wash your hair before the procedure, without using styling products or other cosmetics.
- Get sufficient sleep and rest beforehand, as fatigue may affect brain activity.
- Inform your doctor if you have any metal implants or medical devices that may interfere with the procedure.
Analysis Procedure
For EEG monitoring, special electrodes are placed on the patient’s scalp to record the brain’s electrical activity. The patient must remain relaxed and still for 4 hours. In some cases, the doctor may ask the patient to perform specific tasks or actions to assess brain activity in various states.
What is 4-Hour EEG Monitoring?
4-hour EEG monitoring is a non-invasive procedure that records the brain’s electrical activity using electrodes attached to the scalp. The electroencephalogram (EEG) captures spontaneous electrical signals generated by neurons. The continuous recording over four hours enables doctors to analyze various brain activity patterns and detect possible disorders.
This investigation is part of a comprehensive diagnostic process and is used to evaluate neurological conditions such as epilepsy, sleep disorders, brain injuries, and other brain-related dysfunctions. EEG monitoring can assist in identifying epileptic seizures, determining their type and location, and monitoring the patient’s response to medication.

IMPORTANT!
It is very important to note that the information in this section is not intended for self-diagnosis or self-treatment. In case of pain or worsening of a condition, you must consult a doctor to prescribe the necessary diagnostic investigations. Only a qualified specialist can provide an accurate diagnosis and determine the appropriate treatment.
To obtain the most accurate and consistent analysis results, it is recommended to perform all tests in the same laboratory. This is because different laboratories may use varying methods and measurement units for similar investigations.
