What We Do

Patients with epilepsy tend to have unprovoked seizures. While most patients can be easily helped with antiepileptic medication, about 1 in 3 people will continue to have seizures despite medications. These seizures can also get in the way of a person's everyday life and impact their function and independence. While some patients can be treated with surgery, others have few treatment options.

Some studies have shown that a special diet can reduce seizures. Often referred to as the Ketogenic diet, this is a low carbohydrate, high fat diet which has been proven to help reduce seizures in patients with epilepsy. There are many centres providing this diet for children. However, we have created the first adult epilepsy diet clinic in Ontario. In adults we sometime us a more liberal form of the ketogenic diet called the Modified Atkins Diet which is not as strict as ketogenic diet but is very efficacious. This diet has been shown to help reduce seizures in adults with various types of epilepsy (focal or generalized).

If you think this diet therapy may be right for you, please read our brochure​PDF Icon and ask your doctor to refer you to the Epilepsy Diet Clinic​.​

Tests & Services

The following investigations should be performed before you are seen at the Epilepsy Diet Clinic at TWH

  • Blood tests
  • Urinalysis
  • EKG

Previous investigations of your epilepsy including: (Unless all of your workup has been done at UHN)

  • MRI
  • EEG

Note: if you cannot complete the tests well in advance of your appointment please notify the clinic because we may need to postpone your appointment.​

How to Prepare

Please allocate 2-3 hours for the initial visit as it will likely involve review of your medical history and diet. Follow up visits can be 1-2 hours in duration depending on how you have responded to the diet and the amount of changes that need to be made.

As a tertiary care centre UHN prides itself in not just excellent clinical care but also world renowned research. From time to time you may be asked to participate in a research study. This is very important in this new and expanding field and will greatly benefit future patients. Please note that participating in research is voluntary and will not impact your care. Please let one of your team members know if you have any questions or concerns.​
