Concussion & Brain Injury Treatment at NeuroAxis Health

Advanced, Personalized Care for Lasting Recovery

At NeuroAxis Health, we treat post-concussion symptoms and traumatic brain injuries, supporting patients from early recovery through years after injury. Many experience dizziness, headaches, brain fog, or fatigue—and we can help.

Led by Dr. Rachman Chung, with nearly 20 years of experience, and supported by Dr. Jessica Tolentino’s expertise in neurofeedback and qEEG therapies, our program is one of the Bay Area’s most trusted neurorecovery programs. 

Using precision diagnostics and targeted neuroscience therapies, we go beyond symptom relief to address root causes. Our personalized programs aim to restore clarity, balance, and resilience, helping patients reclaim their best quality of life.

Why Concussion Subtyping Matters

Most concussion symptoms fall into one of seven clinical categories. With precise diagnostic testing, we identify the primary affected areas to create targeted therapy plans that leverage your brain’s ability to heal, strengthen, and function more efficiently.

Concussion Categories

  • Cognitive: Memory, attention, processing speed
  • Mood: Emotional regulation, anxiety, irritability
  • Oculomotor: Eye tracking, depth perception, visual processing
  • Vestibular: Dizziness, balance, sound sensitivity
  • Somatosensory: Headaches, pain, musculoskeletal and proprioceptive issues
  • Autonomic: Heart rate, blood pressure, stress responses
  • Sleep & Energy: Fatigue, sleep disruption, metabolic imbalances

By classifying concussions into these categories, we can selectively activate and strengthen impaired networks rather than relying on generic protocols.

Identifying Concussion Subtypes

The Functional Neurology Evaluation objectively measures how your brain and body systems are functioning to pinpoint the sources of your symptoms and personalize your care plan.

This evaluation examines seven key areas of brain and body function:

Brainwaves (qEEG): Identifies regions functioning too slow, too fast, or inefficiently

Cognition: Measures attention, memory, problem-solving, processing speed

Oculomotor: Evaluates eye movement control and vision pathways

Vestibular: Assesses balance and inner-ear reflexes

Somatosensory: Tests coordination, musculoskeletal, and neurological systems

Autonomic: Examines stress response, heart rate, and blood pressure

Physiology: Ordered when needed to evaluate inflammation, metabolism, or nutrition

This comprehensive evaluation provides the foundation to tailor your recovery journey specifically to your unique concussion subtype and functional profile.

Integrative Therapy Strategies

Our therapy protocols combine advanced, evidence-based treatments, including:

  • Neuromodulation – infrared light and electrical stimulation therapies to stimulate sensory-motor function, promote healing, circulation, and nerve and muscle function.
  • Neurofeedback – training brainwaves to improve sensory-motor integration and communication between networks involved with mood, sleep and cognition.
  • Biofeedback – training the brain and body to self-regulate and improve autonomic nervous system.
  • Neurorehabilitation – task-specific exercises to improve sensory processing, balance, coordination and movement.
  • Vestibular Rehabilitation – restoring stability and reducing dizziness or falls.
  • Chiropractic Care– improving joint mobility and muscle imbalances to improve posture, range of motion and movement. 
  • Lifestyle and Nutrition – to decrease inflammation, increase energy and support brain health. 

This integrated model sparks neuroplasticity, the brain’s ability to reorganize itself, helping restore lost functions or retrain healthy regions to step in where needed.

Ongoing Progress Tracking

Your care doesn’t stop at the initial evaluation. We repeat diagnostic testing at regular intervals so we can:

  • Measure your progress objectively
  • Adjust therapy intensity and focus
  • Ensure you continue moving toward meaningful recovery

Before I went to Dr Chung, I was having imbalance issues, unable to move my eyes in certain ways without causing immediate and severe neurological issues, and plagued with insomnia and night terrors. Dr Chung's treatment was literally the ONLY thing that helped improve my symptoms.

He genuinely cares about his patients' wellbeing and is even willing to work with them on financial issues. I can't recommend him enough!

Dr. Chung is the best in the city, along with his entire staff who are all so friendly, caring, and knowledgeable! I had a horrible nerve issue that was ongoing for a year post-ankle fracture surgery, and saw 5+ doctors that couldn’t diagnose or figure out why I was having the issue. At one point it was difficult to even walk or day to day activities without feeling chronic pain. Then I saw Dr. Chung, who helped me beyond addressing the root cause - and provided a holistic and long-term treatment. My treatment included advanced red-light therapy, physical therapy, chiropractor sessions, and recommendations for lifestyle changes. He’s changed my life for the better, now living pain-free and back to a very active life - so couldn’t recommend Dr. Chung and his team more!

This is a place where healing happens. My brain and I are in a much better place than when I walked through the doors 5 1/2 months ago. Dr. Chung and Dr. Jessica know how to transform the quality of life for each and every patient. My family and friends are happy to see the new me. I’m grateful that I chose NeuroAxis Health and I hope you do too.

In just a few months, Dr. Chung has made such a difference in my life. When I came to Dr. Chung about my migraines, I was at the end of my rope. I’d tried just about every preventative pharmaceutical on the market and was still having migraines multiple times a week, usually requiring triptans for relief. Within weeks of working with Dr. Chung, I was experiencing significantly fewer migraines and today I am happy to report that I’m two months headache-free. I feel better than I ever thought possible and am working with my primary care physician to taper off preventive pharmaceuticals. I know this would not have been possible without Dr. Chung and his team.

Dr. Chung has a comprehensive, innovative, and compassionate approach to diagnostics and care -- he really tried to get to the bottom of what was causing my migraines, and then designed a customized program of treatment that included neurofeedback, chiropractic adjustments, laser and electrical stimulation, and balance and visual rehab. At each step of the process, he explained the data and science behind the process, which helped engage me in the treatment. He is and his colleague, Dr. Fox, are also incredibly kind, and it is a pleasure to work with them. I am so grateful for their work.

Dr. Chung is the reason I’m a functional human again. I had 2 serious head traumas that left me severely impaired, and he helped me heal and resume cognitive and neural functions. I was a wreck! People don’t believe me when I tell them how I was after my injuries. Forever grateful to him. Super knowledgeable, kind, patient, and overall wonderful human! I recommend him to anyone & everyone who suffered a concussion. He’s the best!!

Working with Dr. Chung has been revolutionary for my traumatic brain injury. For the last few years, I have been experiencing post-concussive symptoms related to vision, balance, and coordination. I came to Dr. Chung feeling defeated and hopeless and through his in-depth assessments, he put many of the pieces together and provided personalized treatment that targets my weaknesses. He keeps all of the details in mind when creating the exercises so that nothing is overlooked or missed. He provides his treatment with the push, persistence and understanding that I need to overcome my symptoms. If you are someone who is suffering from balance, vision issues, concussions or brain injury symptoms, Dr. Chung will provide you the right help towards recovery.

Dr. Chung is everything you’d want in a practitioner; he’s kind, knowledgeable, caring and exceptional in his skills. I originally came for migraine help (and haven’t had a single migraine since my first appointment) and am excited to continue the work on this through his very holistic and comprehensive approach (adjustments, Biofeedback and more). Last week I had a serious inflammation in my knee which completely debilitated me. Just left his office with range of motion and significant less pain after he carefully and methodically worked to uncover the source of the injury and how to relieve the pain and adjust the muscles and joints. He also sent me home equipped with gentle exercises to continue the healing. I’ve seen many practitioners in my life and so far Dr. Chung stands out in all the ways that matter when choosing a doctor.
