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. Siu's office or Ontario Health Insurance Plan (OHIP).

Dr. Siu 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 are common diagnostic tests in Neurology?
- Common tests ordered or interpreted by a neurologist include: Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans to visualize the brain and spinal cord; Electroencephalogram (EEG) to record brain electrical activity (often for seizures); Electromyography (EMG) and Nerve Conduction Studies (NCS) to assess nerve and muscle function; Lumbar Puncture (spinal tap) to analyze cerebrospinal fluid; and various blood tests to look for infections, inflammation, or genetic markers. Dr. Siu will determine which tests, if any, are appropriate for your situation.
- What can I expect at my first appointment with Dr. Siu?
- Your first appointment with Dr. Siu 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. Siu 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.
