Traumatic Brain Injury
A brain injury sets off a cascade that can persist for years. We map which networks are struggling and address inflammation, energy, hormones, and rehabilitation.
What you may be noticing
Headaches that never fully leave. Light and noise that feel overwhelming. Memory that drops details, emotions that flare, ringing in the ears, sleep that will not settle, and fatigue after any effort. Digestion, blood pressure, and hormones may have shifted too. Many people with a past brain injury were told they had recovered, yet they know something changed.
Any new head injury with worsening headache, vomiting, confusion, weakness, seizure, or unequal pupils needs emergency care right away.
Why it is rarely one thing
A traumatic brain injury is more than the moment of impact. The force stretches axons and blood vessels, then triggers a metabolic cascade: an energy crisis in neurons, ion imbalance, oxidative stress, and inflammation. In some people, microglia, the immune cells of the brain, remain primed for months or years, keeping symptoms alive long after the bruise has healed. Animal research also shows that injury can slow glymphatic clearance, the waste-removal system of the brain.
Because the brain is the master system, an old injury can sit upstream of symptoms that seem unrelated. The pituitary can lower growth hormone, thyroid, or sex hormone output. The autonomic system can lose balance, affecting blood pressure, digestion, and sleep. The neck and vestibular system often take a hit at the same time. Decades later, the injury may still be the first domino.
Patterns we look for
- Neuroinflammation, microglial priming, and blood-brain barrier integrity.
- Mitochondrial function and brain energy.
- Cerebral blood flow and oxygenation.
- Pituitary function: growth hormone markers, thyroid, cortisol, and sex hormones.
- Autonomic balance: heart rate and blood pressure response on standing.
- Saccades, smooth pursuit, convergence, and vestibular findings.
- Cerebellar and frontal function, which shape coordination, attention, and emotional regulation.
- Cervical spine involvement and sleep with glymphatic clearance.
- Gut permeability, which can rise after brain injury.
- Toxic exposures from military, occupational, or home environments.
How I evaluate it
A comprehensive functional neurological exam measures eye movements in detail, balance, vestibular reflexes, coordination, cranial nerves, and autonomic responses. These findings show which networks are underperforming and how much load each can tolerate.
NeuroQuant volumetric MRI is often valuable after a brain injury, showing regional volume changes that help explain symptoms and track recovery. Functional labs may include a pituitary and hormone panel, a full thyroid panel, cortisol rhythm, fasting insulin, inflammatory markers, omega-3 index, vitamin D, ferritin, and toxicant testing when exposure history points there.
How we address it
The first phase is not detoxification. It is neurological safety.
- Regulate: autonomic and vagal practices, steady blood sugar, and sleep restoration.
- Support circulation, oxygenation, and glymphatic drainage with breathing, gentle neck mobility, and movement.
- Fuel mitochondria with a brain-supportive food plan and remove inflammatory foods and alcohol.
- Rebalance hormones and autonomic function, coordinating with endocrinology when needed.
- Rebuild with brain-based rehabilitation: smooth pursuits and saccades first, then vestibular, convergence, balance, and cognitive training. Symptoms may rise two or three points on a ten-point scale during an exercise and no further; if they climb higher, you stop, rest, and resume at a shorter duration.
- Only once the nervous system is steadier and drainage is flowing do we address deeper toxic burden.
Repetition and consistency build neuroplasticity, not intensity. An injured brain can still change, and the right inputs, in the right order, give it reason to.
