Based on this, Dr. Royer-Perron 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.

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.

For frequent or severe migraines, preventive treatments may be prescribed, which can include oral medications, botulinum toxin (Botox) injections, or newer CGRP monoclonal antibodies.
