Dr. David Kwok Wai Chan

Dr. David Chan addresses a wide range of neurological conditions, including:

Common Neurological Symptoms (Requiring Evaluation)

• Memory Loss & Cognitive Changes: Difficulties with memory, concentration, language, or problem-solving that interfere with daily life.
• Persistent or Severe Headaches / Migraines: Head pain that is frequent, debilitating, or associated with other neurological symptoms like aura or nausea.
• Dizziness, Vertigo & Balance Problems: Sensations of spinning, unsteadiness, or lightheadedness that may indicate an underlying neurological issue.

Headache Disorders

• Cluster Headache: Intensely painful headaches that occur in cyclical patterns or cluster periods, one of the most severe types of pain known.
• Trigeminal Neuralgia & Other Facial Pain Syndromes: Chronic pain conditions affecting the trigeminal nerve, causing severe facial pain.
• Migraine (with or without Aura): A type of headache that can cause severe throbbing pain or a pulsing sensation, often accompanied by nausea, vomiting, and sensitivity to light and sound.

Cognitive Disorders & Dementia

• 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.
• Vascular Dementia: Dementia caused by reduced blood flow to the brain, often due to stroke or a series of small strokes.
• Mild Cognitive Impairment (MCI): An intermediate stage between the expected cognitive decline of normal aging and the more serious decline of dementia.

This list is not exhaustive. For personalized advice regarding your specific neurological concerns, please consult with Dr. David Chan.

• Comprehensive Neurological Consultation & Examination: In-depth evaluation of symptoms related to the brain, spinal cord, nerves, and muscles, including detailed medical history, neurological examination, and diagnostic planning.
• 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.
• Evoked Potential Studies (Visual, Auditory, Somatosensory): Tests that measure the electrical activity in the brain in response to stimulation of sight, sound, or touch, often used in diagnosing MS and other conditions.
• 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.
• 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.

Note: This list provides a general overview. Treatment plans are individualized. Discuss with Dr. Chan for care relevant to your needs.

All medical services are provided in accordance with the standards of practice set by the College of Physicians and Surgeons of Ontario (CPSO) and relevant neurological care guidelines. Contact the clinic regarding new patient intake and referral processes.

Are consultations and treatments with Dr. Chan, a Neurologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations with a licensed Neurologist like Dr. Chan, as well as many diagnostic tests (e.g., EEG, EMG, review of MRI/CT scans), are generally covered by Ontario Health Insurance Plan (OHIP) in ON 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. Chan's office or Ontario Health Insurance Plan (OHIP).

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

Yes, a referral from your family physician or another specialist is almost always required to see a Neurologist like Dr. Chan 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 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. Chan can provide a comprehensive overview of MS and develop a personalized treatment plan based on your specific type of MS and disease activity.

What can I expect at my first appointment with Dr. Chan?

Your first appointment with Dr. Chan 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. Chan 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.

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. Chan will determine which tests, if any, are appropriate for your situation.
