Dr. Carlos Quenguan 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.
• Seizures or Episodes of Loss of Consciousness: Events involving abnormal electrical brain activity or unexplained blackouts requiring neurological assessment.
• Dizziness, Vertigo & Balance Problems: Sensations of spinning, unsteadiness, or lightheadedness that may indicate an underlying neurological issue.

Epilepsy & Seizure Disorders

• Refractory (Drug-Resistant) Epilepsy: Epilepsy that does not respond adequately to treatment with two or more appropriately chosen anti-seizure medications.
• Generalized Epilepsy (e.g., Tonic-Clonic, Absence Seizures): Seizures that affect both sides of the brain from the onset, leading to various types of convulsions or alterations in consciousness.
• Focal (Partial) Epilepsy (with or without secondary generalization): Seizures originating in one area of the brain, which may or may not spread to become generalized.

Neuromuscular Diseases

• Guillain-Barré Syndrome (GBS): A rare neurological disorder in which the body's immune system mistakenly attacks part of its peripheral nervous system.
• 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.
• Myasthenia Gravis: A chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body.

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

• 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.
• 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.
• 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.
• Intraoperative Neurophysiological Monitoring (IONM) - Consultation/Oversight: Monitoring of nervous system function during surgeries that pose a risk to neurological structures.
• 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.
• 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.

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

Some specialized procedures or devices may also have specific coverage criteria. It's always best to discuss coverage specifics with Dr. Quenguan's office or Ontario Health Insurance Plan (OHIP).

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

Yes, a referral from your family physician or another specialist is almost always required to see a Neurologist like Dr. Quenguan 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 does a Neurologist like Dr. Quenguan specialize in?

A Neurologist is a medical doctor who specializes in the diagnosis, treatment, and management of disorders affecting the nervous system. This includes the brain, spinal cord, peripheral nerves (nerves outside the brain and spinal cord), and muscles. He is a Neurologist specializing in disorders of the nervous system. Dr. Quenguan is trained to investigate, diagnose, and treat a wide range of neurological conditions.

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. Quenguan can discuss the most appropriate treatment pathway.

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

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. Quenguan can provide a comprehensive overview of MS and develop a personalized treatment plan based on your specific type of MS and disease activity.
