Video-EEG monitoring, standard protocol, 20 min

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. 20-minute 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

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 20 minutes. In some cases, the doctor may ask the patient to perform specific tasks or actions to assess brain activity in various states.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

20-minute 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

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.

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.
