EEG examination (Prague)

How does the EEG examination work and how long does it take?

During the examination, electrodes are attached to the patient's scalp to sense the brain's electrical potentials. These potentials are recorded by an electroencephalograph and displayed as waves on a monitor or paper. The examination is painless and usually takes 20 to 40 minutes. During the brain scan (EEG), the patient may be asked to perform various tasks such as opening and closing the eyes or deep breathing.

It is important to wash your hair before an EEG scan in children and adults to ensure good contact between the electrodes and the scalp. Conversely, it is not recommended to use hair products such as gels or weights.

The most common indications for EEG examination:

• Epilepsy and other seizure conditions
• Sleep disorders
• Disorders of consciousness
• Inflammations of the brain (encephalitis)
• Brain tumors
• Head injuries
• Migraines and other headaches
• Diagnosis of brain death

When to get an EEG scan?

You should seek an EEG examination if you suffer from recurrent seizures, sleep disturbances, sudden loss of consciousness, or if you suspect another neurological condition. EEG is also important for monitoring patients after head injuries or brain surgery. Do not hesitate to contact our neurology (Prague).
