Functional neurology is an evolving field of healthcare that focuses on the health and performance of the nervous system. Unlike traditional neurology, which often looks for physical damage or disease, functional neurology looks at how well the brain and nerves are communicating. By identifying areas of the brain that are underperforming, practitioners use specific exercises to help the brain rewire itself and improve overall function.
Understanding the Basics of Functional Neurology
To understand functional neurology, it is helpful to think of the brain like a computer. Traditional neurology focuses on the “hardware”—looking for physical issues like tumors, lesions, or bleeding. If the hardware is intact, a traditional neurologist may find nothing wrong during a standard scan.
Functional neurology focuses on the “software.” It examines how the signals are moving through the nervous system. Even if the structure of the brain is healthy, the way it processes information can be inefficient. This inefficiency can lead to a wide range of symptoms, from balance issues to chronic pain.
The primary goal of a functional neurologist is to restore balance to the nervous system. They do this by utilizing the brain’s natural ability to change, a concept known as neuroplasticity. Through targeted stimulation, the brain can form new pathways and strengthen existing ones.
Functional Neurology vs. Traditional Neurology
While both fields deal with the nervous system, their approaches to treatment are quite different. Traditional neurology typically uses medication or surgery to treat acute conditions and diseases. This is essential for managing serious issues like strokes, epilepsy, or multiple sclerosis.
Functional neurology is generally non-invasive and drug-free. Practitioners, who are often specialized chiropractors or medical doctors, use physical and sensory exercises to treat patients. They look for subtle imbalances in how the left and right sides of the brain interact.
In many cases, functional neurology is used as a complementary therapy. It works alongside traditional medicine to help patients recover from lingering symptoms that medication alone might not address. It is a proactive approach focused on rehabilitation and optimization.
Common Conditions Addressed
Because the nervous system controls every part of the body, functional neurology can be applied to many different health concerns. Patients often seek this type of care when they feel something is “off” but standard medical tests come back normal.
- Post-Concussion Syndrome: Helping the brain recover after a head injury by retraining eye movements and balance.
- Vertigo and Dizziness: Addressing issues in the vestibular system (the inner ear and brain connection) to restore stability.
- Movement Disorders: Managing tremors or coordination issues by strengthening specific motor pathways.
- Chronic Pain: Retraining the brain’s perception of pain signals to reduce long-term discomfort.
- Childhood Developmental Disorders: Supporting children with ADHD or autism by stimulating areas of the brain responsible for focus and social interaction.
- Migraines and Headaches: Identifying triggers in the nervous system and reducing the brain’s sensitivity to those triggers.
The Role of Neuroplasticity
The foundation of functional neurology is neuroplasticity. For a long time, scientists believed the brain was fixed after childhood. We now know that the brain is dynamic and can change throughout a person’s entire life.
When a specific part of the brain is not stimulated enough, it can become weak. Functional neurologists identify these weak areas and provide targeted input—such as light, sound, or movement—to activate them. Over time, this repeated stimulation encourages the brain to build stronger connections.
This process is similar to physical therapy for a muscle. If you have a weak arm, you perform specific exercises to make it stronger. Functional neurology applies this same logic to the neurons in your brain.
What to Expect During an Initial Visit
An initial consultation with a functional neurologist is typically very thorough. Because they are looking for functional imbalances, they perform a wide variety of tests that you might not experience in a standard doctor’s office.
Comprehensive History
The practitioner will ask detailed questions about your health history, including old injuries, sleep patterns, and diet. They want to understand the total load on your nervous system.
Physical and Neurological Exams
You may undergo tests that check your reflexes, muscle strength, and sensitivity to touch. The practitioner will also look for signs of autonomic nervous system issues, such as changes in heart rate or blood pressure when you change positions.
Eye Movement Analysis
One of the most important tools in functional neurology is the study of eye movements. The way your eyes track an object or jump between points provides a direct window into how different parts of your brain are functioning. They may use specialized goggles to record these movements.
Balance and Coordination Testing
You might be asked to stand on a pressure plate (posturography) to measure your stability. These tests help the practitioner determine if your brain is accurately perceiving where your body is in space.
Common Treatment Techniques
Once the assessment is complete, the practitioner creates a personalized rehabilitation plan. These treatments are designed to be performed in the office and often continued at home.
- Gaze Stabilization: Exercises where you focus on a target while moving your head to improve the connection between your eyes and inner ear.
- Sensory Stimulation: Using specific frequencies of light or sound to activate one side of the brain more than the other.
- Vestibular Rehabilitation: Physical movements designed to treat dizziness and improve balance.
- Cognitive Tasks: Mental exercises performed simultaneously with physical movements to increase the “load” on the brain.
- Chiropractic Adjustments: Precise joint manipulations intended to send specific sensory signals to the brain.
How to Find a Qualified Practitioner
If you are interested in functional neurology, it is important to find a provider with the right credentials. Most functional neurologists are Doctors of Chiropractic (DC) who have completed extensive post-graduate training.
Look for practitioners who are board-certified by the American Chiropractic Neurology Board (ACNB). These individuals carry the title of DACNB (Diplomate of the American Chiropractic Neurology Board). This certification ensures they have met high standards of education and clinical competency in the field.
It is also helpful to ask about their experience with your specific condition. Many practitioners specialize in certain areas, such as traumatic brain injury or childhood developmental issues.
Is Functional Neurology Right for You?
Functional neurology is often a good fit for individuals who have “slipped through the cracks” of traditional medicine. If you have been told that your tests are normal but you still feel unwell, a functional approach may provide the answers you need.
However, it requires commitment. Because the goal is to rewire the brain, treatments often involve daily exercises and multiple office visits. It is a collaborative process between the patient and the provider.
Always consult with your primary care physician before starting a new type of therapy. Functional neurology should be seen as one part of a comprehensive approach to your health and well-being.
By focusing on how the brain functions rather than just its structure, functional neurology offers a unique path to recovery and performance. Whether you are recovering from an injury or simply want to sharpen your mental clarity, understanding your nervous system is a powerful step toward better health.
