Common Neurological Symptoms (Requiring Evaluation)

• Dizziness, Vertigo & Balance Problems: Sensations of spinning, unsteadiness, or lightheadedness that may indicate an underlying neurological issue.
• Numbness, Tingling & Weakness (Focal or Generalized): Sensory changes or loss of strength in limbs or other body parts, potentially due to nerve or muscle disorders.
• Seizures or Episodes of Loss of Consciousness: Events involving abnormal electrical brain activity or unexplained blackouts requiring neurological assessment.

Multiple Sclerosis & Demyelinating Diseases

• Transverse Myelitis: Inflammation of the spinal cord, often causing weakness, sensory changes, and autonomic dysfunction below the level of the lesion.
• Multiple Sclerosis (MS) - Relapsing-Remitting, Primary Progressive, Secondary Progressive: A chronic autoimmune disease affecting the central nervous system (brain and spinal cord) by damaging the myelin sheath.
• Acute Disseminated Encephalomyelitis (ADEM): A rare inflammatory demyelinating condition of the central nervous system, typically following an infection or vaccination.

Stroke & Cerebrovascular Diseases

• Transient Ischemic Attack (TIA) / Mini-Stroke: A temporary blockage of blood flow to the brain, often a warning sign for a future stroke.
• Ischemic Stroke: Occurs when a blood vessel supplying blood to the brain is obstructed, leading to brain cell damage.
• Carotid Artery Stenosis (Symptomatic): Narrowing of the carotid arteries in the neck, increasing stroke risk if it causes neurological symptoms.

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

• Management of General Neurological Conditions: Ongoing care for a variety of common neurological issues, including follow-up, medication management, and lifestyle counseling.
• 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.
• 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.
• 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.

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

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

Medically necessary consultations with a licensed Neurologist like Dr. Gonorazky, 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. Gonorazky's office or Ontario Health Insurance Plan (OHIP).

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

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

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. Gonorazky if needed.

How are migraines typically managed by a Neurologist?

Migraine management is multifaceted. Dr. Gonorazky 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.

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. Gonorazky 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.

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

Your first appointment with Dr. Gonorazky 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. Gonorazky 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.
