E.E.G.

E.E.G., or Electroencephalography, is a non-invasive diagnostic test used to record the electrical activity of the brain. It is an important tool for identifying various neurological conditions and understanding how the brain functions. Our EEG Department is equipped with modern digital EEG machines that capture detailed brainwave patterns, ensuring accurate diagnosis and effective treatment planning. The procedure is safe, painless, and suitable for patients of all ages, including children and elderly individuals.

What is an EEG and Why It Is Done

An EEG measures the electrical signals produced by brain cells. These signals help doctors detect abnormalities that may be causing symptoms such as seizures, headaches, dizziness, memory issues, loss of consciousness, or unusual behavior. The test is commonly used to diagnose epilepsy, sleep disorders, brain infections, head injuries, and other neurological conditions. By studying the brainwave patterns, neurologists can understand how the brain is functioning and identify any irregular activity that needs medical attention.

How the EEG Procedure Works

During the EEG procedure, small sensors called electrodes are placed gently on the scalp using a special gel. These electrodes detect electrical impulses from the brain and transmit the signals to a computer, where they are displayed as wave patterns. The patient is asked to relax, remain still, and follow simple instructions such as opening or closing the eyes or breathing deeply. In some cases, activating tests like flashing lights or sleep EEG may be performed to capture specific brain activity. The test is completely painless and usually takes 30 to 60 minutes.

Types of EEG Tests

Different types of EEG tests are conducted based on the patient’s condition and the doctor’s recommendation. A standard EEG records brain activity while the patient is awake, while a sleep EEG captures patterns during sleep to diagnose sleep-related disorders. Video EEG monitoring is used for patients with frequent seizures, combining continuous EEG recording with video observation. This helps doctors identify the exact type of seizure and the affected area of the brain, allowing for more accurate treatment.

Conditions Diagnosed Using EEG

EEG plays a vital role in diagnosing neurological conditions such as epilepsy, seizure disorders, brain inflammation, stroke, sleep disorders, and certain psychiatric conditions. It helps determine whether seizures are caused by electrical disturbances in the brain and guides doctors in choosing the right medications or treatment plans. EEG is also beneficial in assessing brain function after head injuries, during coma evaluation, and before brain surgery.

Safe, Non-Invasive and Reliable Testing

EEG is one of the safest diagnostic tests available, as it does not involve radiation, injections, or any form of discomfort. Patients can resume their regular activities immediately after the test. With modern digital technology, the recordings are highly accurate, allowing doctors to interpret even the smallest abnormalities. This reliability makes EEG an essential tool in neurological diagnosis and long-term monitoring.

Patient-Centered Care

Our team ensures a comfortable and reassuring experience for every patient undergoing EEG testing. The procedure is clearly explained beforehand, and patients are assisted at every step. For children and anxious individuals, special care is taken to keep them relaxed throughout the process. After the test, the results are reviewed by experienced neurologists who provide a clear explanation and guide patients toward appropriate treatment or further evaluation if needed.
