What if one of the missing pieces in concussion recovery isn't in the brain—but in the neck?
In this episode of Life After Impact, Dr. Ayla Wolf welcomes back functional neurologist Dr. John McClaren for a fascinating conversation about the hidden relationship between dysautonomia, neck dysfunction, and persistent post-concussion symptoms. Together, they explore why so many people experience dizziness when bending over, standing up, or looking overhead—and why these seemingly simple movements may reveal much deeper dysfunction within the autonomic nervous system.
Dr. McClaren shares emerging clinical observations suggesting that deep neck flexor dysfunction, restricted mobility of the anterior neck, and impaired sensory integration may play a much larger role in concussion recovery than previously recognized. The discussion also explores how breathing mechanics, vagus nerve function, glymphatic drainage, visual processing, smell, and auditory localization all interact to influence brain function and autonomic regulation.
Together, they discuss:
- Why dysautonomia has become increasingly common after concussion
- The surprising role of the deep neck flexor muscles in headaches and autonomic dysfunction
- How manual therapy may improve brain function beyond simply reducing neck pain
- The connection between breathing mechanics, airway function, and nervous system regulation
- The glymphatic system and why the neck may be critical for clearing metabolic waste from the brain
- Why visual overload, bright lights, and busy environments overwhelm the injured brain
- New approaches to visual rehabilitation using color perception and peripheral vision
- Smell retraining, auditory localization, and sensory mapping as tools for neurorehabilitation
- Why effective concussion rehabilitation requires treating the brain as an interconnected sensory network
One of the most powerful takeaways from this conversation is that concussion recovery isn't about fixing one isolated symptom. It's about helping the brain rebuild efficient communication across multiple sensory systems so that everyday activities once again become automatic instead of exhausting.
Whether you're recovering from a concussion, living with dysautonomia, or simply interested in the latest developments in functional neurology, this episode offers practical insights and exciting new ideas that may change the way you think about brain rehabilitation.
