We use electroencephalography (EEG) to assess brain activity and assist in the diagnosis of epilepsy and other neurological conditions.
Epilepsy is a neurological disorder characterised by unpredictable and recurrent seizures. It is the fourth most common neurological disorder, affecting nearly 65 million people worldwide. Epilepsy is usually managed with medications or surgery, and in some cases lifestyle modifications are recommended to help manage symptoms.
People living with epilepsy may face challenges with everyday activities such as driving, taking part in sports, or socialising. With proper diagnosis, management, and support from family and friends, however, those living with epilepsy can lead fulfilling and productive lives.
Diagnosis is typically made through EEG (electroencephalography), which measures the electrical activity in the brain. EEG is a crucial diagnostic tool that allows doctors to identify the type of seizure and develop the most effective treatment plan for the patient.
Epilepsy can result from a range of underlying causes, including:
A vagus nerve stimulator (VNS) is a small, implantable medical device placed under the skin in the chest area, with a wire attached to the left vagus nerve in the neck. The device delivers mild, regular electrical pulses to the vagus nerve, which carries these signals to the brain. VNS is believed to help regulate abnormal electrical activity in the brain, reducing the frequency and severity of seizures.
An EEG (electroencephalogram) measures the electrical activity of the brain by placing electrodes on the scalp. These electrodes detect and record patterns of electrical activity produced by neurons in the brain.
We strive to make healthcare accessible and convenient for you
You will be asked to lie on a bed or reclining chair while a technician applies electrodes to your scalp using a special adhesive paste. The number of electrodes typically ranges from 16 to 32. You will then be asked to relax with your eyes closed for 20-30 minutes while brain activity is recorded. During this time, you may be asked to breathe deeply or have flashing lights presented to stimulate specific brain areas.
The recording phase typically takes 20-30 minutes. Including preparation and setup, you should allow approximately one to one and a half hours for your appointment.
Yes. During the EEG you need to remain still and quiet with your eyes closed for an extended period. We make every effort to ensure you are comfortable before we begin.
For an overnight or 24-hour EEG, you will be sent home with the electrodes secured to your head and a small portable EEG device. You may continue normal daily activities while the EEG is connected. The electrodes are removed the following morning.
A neurophysiologist who specialises in interpreting EEGs will analyse the data alongside other relevant medical information and produce a detailed report for your referring doctor.
After VNS implantation, patients are scheduled for follow-up appointments with our neurophysiologist. Initially, appointments are held every 2-4 weeks to gradually increase the VNS settings. The process of reaching the optimal setting can take up to three months. Once the desired setting is achieved, patients transition to six-monthly check-ups to assess the VNS and monitor battery levels.
Potential side effects of VNS therapy may include hoarseness, throat discomfort, cough, headaches, shortness of breath, and difficulty swallowing. These are monitored closely during the adjustment phase.
