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. Gagné-Brosseau 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. Gagné-Brosseau can discuss the most appropriate treatment pathway.

When should I consider seeing a Neurologist?

You should consider seeing a Neurologist if you experience persistent or concerning symptoms such as: severe or frequent headaches (especially if new or different), chronic dizziness or vertigo, numbness or tingling in your limbs, unexplained weakness, seizures or blackouts, memory problems or cognitive decline, difficulties with movement or coordination (like tremors or unsteady gait), or significant changes in vision not explained by eye problems.
