Video-EEG monitoring with daytime recording - 2 hours
Electroencephalography (EEG) is a method of recording the brain’s electrical activity, allowing for the assessment of the functional state of various areas of the cerebral cortex and deep brain structures. Two-hour EEG monitoring is performed to identify possible 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 in different areas of the brain. The data is recorded and analyzed by a neurophysiology specialist to identify any deviations from normal activity.
EEG monitoring is a safe and non-invasive procedure that provides valuable information about brain function and supports the diagnosis of various neurological disorders.
Purpose of Two-Hour EEG Monitoring
Two-hour EEG monitoring is an important diagnostic tool that enables the evaluation of brain activity and the detection of potential abnormalities. This extended observation period allows the recording of changes in brain electrical activity, which can assist in diagnosing conditions such as epilepsy, sleep disorders, brain injuries, and others.
Indications for Two-Hour EEG Monitoring
Two-hour EEG monitoring may be indicated in the following situations:
- Suspected epilepsy or other seizure disorders: Extended EEG recording allows detection of epileptic activity and supports the diagnosis of various forms of epilepsy.
- Evaluation after traumatic brain injury: EEG monitoring can detect abnormal brain activity and track recovery after head trauma.
- Assessment of sleep disorders: EEG is used to diagnose different types of sleep disorders, such as sleep apnea, insomnia, and others.
- Neurological disease monitoring: Prolonged EEG recording can help assess brain activity in conditions such as Alzheimer’s disease, Parkinson’s disease, and other neurological disorders.
Preparation for the EEG Procedure
No special preparation is required for two-hour EEG monitoring. However, the following recommendations should be observed:
- Avoid caffeine-containing beverages (coffee, energy drinks) a few hours before the procedure, as they may affect the results.
- Wash your hair beforehand, without using styling products or other cosmetics.
- Get a good night’s sleep and rest well before the procedure, as fatigue may influence brain activity.
- Inform your doctor of any metal implants or devices that could interfere with the procedure.
Procedure Description
For EEG monitoring, special electrodes are placed on the patient’s scalp to record brain electrical activity. The patient is required to relax and remain still for 2 hours. In some cases, the doctor may ask the patient to perform specific tasks or actions to evaluate brain activity under different conditions.
What is Two-Hour EEG Monitoring?
Two-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 the spontaneous electrical signals generated by neurons in the brain. Continuous recording over an extended period allows doctors to analyze various brain activity patterns and identify possible disorders.
This examination is part of a comprehensive diagnostic process and is used to evaluate various neurological conditions such as epilepsy, sleep disorders, brain injuries, and other brain function disorders. EEG monitoring can help detect epileptic seizures, determine the type and location of the seizure focus, and monitor the patient's response to medication.

IMPORTANT!
Este foarte important să rețineți că informațiile din această secțiune nu sunt destinate autodiagnosticării și tratamentului. În caz de durere sau exacerbare a unei boli, este necesar să consultați un medic pentru a prescrie investigații diagnostice. Doar un specialist calificat poate pune un diagnostic corect și poate determina tratamentul adecvat. Pentru obținerea celor mai precise și consistente evaluări ale rezultatelor analizelor, se recomandă efectuarea acestora în același laborator. Acest lucru se datorează faptului că diferite laboratoare pot utiliza metode și unități de măsură diferite pentru efectuarea unor investigații similare.
