Dr. Jean-Sébastien Langlais addresses a wide range of neurological conditions, including:
Common Neurological Symptoms (Requiring Evaluation)
- Dizziness, Vertigo & Balance Problems: Sensations of spinning, unsteadiness, or lightheadedness that may indicate an underlying neurological issue.
- Seizures or Episodes of Loss of Consciousness: Events involving abnormal electrical brain activity or unexplained blackouts requiring neurological assessment.
- Memory Loss & Cognitive Changes: Difficulties with memory, concentration, language, or problem-solving that interfere with daily life.
Neuromuscular Diseases
- Peripheral Neuropathy (e.g., Diabetic, Chemotherapy-induced, Idiopathic): Damage to or disease affecting nerves, which may impair sensation, movement, gland or organ function, or other aspects of health.
- Amyotrophic Lateral Sclerosis (ALS) / Motor Neuron Disease: A progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord, leading to muscle weakness and paralysis.
- Guillain-Barré Syndrome (GBS): A rare neurological disorder in which the body's immune system mistakenly attacks part of its peripheral nervous system.
Cognitive Disorders & Dementia
- Vascular Dementia: Dementia caused by reduced blood flow to the brain, often due to stroke or a series of small strokes.
- Frontotemporal Dementia (FTD): A group of disorders that primarily affect the frontal and temporal lobes of the brain, leading to changes in personality, behavior, and language.
- Lewy Body Dementia: A type of progressive dementia that leads to a decline in thinking, reasoning and independent function, often with visual hallucinations and parkinsonian features.
This list is not exhaustive. For personalized advice regarding your specific neurological concerns, please consult with Dr. Jean-Sébastien Langlais.
- Management of General Neurological Conditions: Ongoing care for a variety of common neurological issues, including follow-up, medication management, and lifestyle counseling.
- Electroencephalography (EEG) - Performance & Interpretation: Recording and analysis of electrical activity in the brain, primarily used to diagnose epilepsy, seizures, and other brain disorders.
- Interpretation of Neurological Imaging (MRI, CT scans): Expert review and interpretation of brain and spinal cord imaging to aid in the diagnosis of neurological conditions.
- Electromyography (EMG) & Nerve Conduction Studies (NCS) - Performance & Interpretation: Diagnostic tests to assess the health of muscles and the nerve cells that control them (motor neurons), helping diagnose nerve damage, muscle diseases, and radiculopathies.
- Second Opinion Consultations for Neurological Disorders: Providing expert second opinions on complex neurological diagnoses and proposed treatment plans to ensure informed patient decision-making.
- Lumbar Puncture (Spinal Tap) - Performance or Referral & Interpretation: Procedure to collect cerebrospinal fluid for diagnostic testing of conditions like meningitis, encephalitis, MS, or certain neurological infections.
- Intraoperative Neurophysiological Monitoring (IONM) - Consultation/Oversight: Monitoring of nervous system function during surgeries that pose a risk to neurological structures.

- Are consultations and treatments with Dr. Langlais, a Neurologist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?
- Medically necessary consultations with a licensed Neurologist like Dr. Langlais, as well as many diagnostic tests (e.g., EEG, EMG, review of MRI/CT scans), are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC 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. Langlais's office or Régie de l'assurance maladie du Québec (RAMQ).
- Do I need a referral to see Dr. Langlais, a Neurologist?
- Yes, a referral from your family physician or another specialist is almost always required to see a Neurologist like Dr. Langlais 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.
- 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. Langlais will determine which tests, if any, are appropriate for your situation.
- 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. Your family doctor can evaluate your symptoms and refer you to a neurologist like Dr. Langlais if needed.
- What can I expect at my first appointment with Dr. Langlais?
- Your first appointment with Dr. Langlais will likely be quite thorough. He 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. Langlais 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.
- How does Dr. Langlais 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. Langlais 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.
