Are consultations and treatments with Dr. Sun, a Neurologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations with a licensed Neurologist like Dr. Sun, as well as many diagnostic tests (e.g., EEG, EMG, review of MRI/CT scans), are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor or another specialist is in place. Coverage for specific medications, especially newer biologic therapies for conditions like MS or migraine, can vary by provincial formularies and may require special authorization. Some specialized procedures or devices may also have specific coverage criteria. It's always best to discuss coverage specifics with Dr. Sun's office or Ontario Health Insurance Plan (OHIP).

Do I need a referral to see Dr. Sun, a Neurologist?

Yes, a referral from your family physician or another specialist is almost always required to see a Neurologist like Dr. Sun for assessment or treatment of a neurological condition. This ensures your care is coordinated, that preliminary investigations may have been done, and that you are directed to the most appropriate specialist for your specific symptoms or suspected diagnosis.

How are migraines typically managed by a Neurologist?

Migraine management is multifaceted. Dr. Sun will work with you to identify triggers, discuss lifestyle modifications (diet, sleep, stress management), and recommend acute treatments to stop a migraine when it occurs (e.g., triptans, CGRP antagonists). For frequent or severe migraines, preventive treatments may be prescribed, which can include oral medications, botulinum toxin (Botox) injections, or newer CGRP monoclonal antibodies. A personalized treatment plan is key.

What can I expect at my first appointment with Dr. Sun?

Your first appointment with Dr. Sun will likely be quite thorough. She will take a detailed medical history, including your current symptoms, past illnesses, family history of neurological conditions, and any medications you are taking. A comprehensive neurological examination will be performed, which assesses things like your mental status, cranial nerves (vision, hearing, facial movement), strength, coordination, reflexes, and sensation. Based on this, Dr. Sun may discuss potential diagnoses, order further tests (like an MRI, EEG, or blood work), or suggest initial treatment options. Bring a list of your medications and any relevant medical records or imaging reports if you have them.

What is Multiple Sclerosis (MS) and how is it treated?

Multiple Sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (brain and spinal cord), leading to a variety of neurological symptoms. Treatment focuses on managing acute relapses (often with corticosteroids), slowing disease progression with disease-modifying therapies (DMTs), and managing symptoms (like fatigue, spasticity, pain, bladder problems). Dr. Sun can provide a comprehensive overview of MS and develop a personalized treatment plan based on your specific type of MS and disease activity.

What are the treatment options for epilepsy?

The primary treatment for epilepsy is anti-seizure medication (ASM), formerly known as anti-epileptic drugs (AEDs). There are many different ASMs available, and the choice depends on the type of seizures, epilepsy syndrome, age, other medical conditions, and potential side effects. For some individuals whose seizures are not controlled by medication (drug-resistant epilepsy), other options may include dietary therapies (like the ketogenic diet), neurostimulation devices (like Vagus Nerve Stimulation - VNS), or epilepsy surgery. Dr. Sun can discuss the most appropriate treatment pathway.
