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

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

Yes, a referral from your family physician or another specialist is almost always required to see a Neurologist like Dr. Nikneshan 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. Nikneshan 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.

How does Dr. Nikneshan manage Parkinson's disease?

Management of Parkinson's disease is aimed at controlling symptoms and improving quality of life. This typically involves medications that increase dopamine levels in the brain (like levodopa) or mimic its effects. Other medications can help with non-motor symptoms. Dr. Nikneshan will also emphasize the importance of exercise, physical therapy, occupational therapy, and speech therapy. For some patients with advanced Parkinson's disease, Deep Brain Stimulation (DBS) surgery may be an option. Care is highly individualized.

What does a Neurologist do for stroke patients?

For acute ischemic stroke, neurologists in a hospital setting are involved in rapid diagnosis and administration of time-sensitive treatments like thrombolysis (clot-busting medication) or coordinating endovascular thrombectomy. After a stroke or TIA (transient ischemic attack), a neurologist like Dr. Nikneshan focuses on identifying the cause and implementing strategies for secondary prevention to reduce the risk of future strokes. This includes managing risk factors like high blood pressure, diabetes, high cholesterol, atrial fibrillation, and recommending antiplatelet or anticoagulant medications and lifestyle changes.
