Most people picture a concussion as something dramatic — a hit, a knockout, an ambulance. Dr. Ken Oliver, a chiropractic neurologist who runs The Neuro Clinic, spent this conversation with Mark Anthony making the opposite case: most concussions look nothing like that. They show up instead as a headache that won't quit, a short temper that seems to come out of nowhere, or a sensitivity to light that never used to be there — and most people never trace it back to a head injury at all.
Oliver's path started with an exercise science degree from Brigham Young University, followed by chiropractic school after a period of service work for his church. It was only after graduation, he said, that he found a specialty niche within chiropractic focused specifically on neurology — and it became, in his words, his "life's passion to learn as much as I can about the brain." Today his practice works with concussions, vertigo, neuropathy, movement disorders, and behavioral conditions like ADD, dyslexia, and autism. He was direct about the boundaries of his scope: he doesn't prescribe medication or perform surgery, and treats that as a constraint that shapes his approach rather than limits what he can help with.
Key Takeaways
- The Neuro Clinic uses three objective diagnostic tools — saccadometry, computerized posturography, and videonystagmography — plus the FDA-approved EyeBox device, rather than relying on a symptom checklist alone.
- Concussion symptoms extend well beyond headaches: light and sound sensitivity, ringing in the ears, fatigue, depression, and out-of-character anger or irritability tied to frontal lobe function.
- Two simple starting-point exercises Dr. Oliver recommends: "slingshot saccades" (alternating eye and head focus between two targets) and gargling, which he says stimulates vagal nerve tone.
- He described research showing many people develop some degree of leaky gut within 30 to 60 minutes of a head injury — part of why he treats concussion recovery as a whole-body issue rather than isolating it to the brain.
- His practice runs largely cash-pay (aside from personal injury cases), and he was candid about frustrations with insurance — including the multiple medications patients must be shown to have failed before TMS therapy is even considered for coverage.
How a Concussion Actually Gets Diagnosed
Rather than working off a symptom checklist, Oliver said his office runs what he called the medical gold standard for identifying a concussed brain. Saccadometry measures fast eye movements to evaluate frontal eye field function — a window into how well the frontal lobe, which governs decision-making, impulse control, focus, and mood regulation, is actually working. That's paired with computerized posturography (a balance assessment) and videonystagmography (tracking how well the eyes follow a moving target). The newest addition to his practice, added within the past year, is the EyeBox, a device from a company called Oculogica that Oliver described as the first FDA-approved device able to help diagnose a concussion without requiring a separate baseline test. Together, he said, the testing lets his team confirm a head injury and then track the resulting cascade of symptoms: light sensitivity, sound sensitivity, headaches, ringing in the ears, depression, and fatigue among them.
"I don't prescribe medications and I don't do surgery. So if you want me to help you, I'm going to do everything I know how to do without using drugs and surgery, because oftentimes that's just not the answer."
— Dr. Ken OliverThe Symptoms Most People Never Connect to a Head Injury
One of the most overlooked concussion symptoms, Oliver said, is a sudden shift in temperament — anger, irritability, or impulsiveness that seems to appear out of nowhere. He pointed to the well-known case of Phineas Gage, the 19th-century railroad foreman whose skull was pierced by an iron rod in an explosion; Gage survived, but afterward became, in Oliver's telling, "the town pariah" because the injury had damaged his frontal lobe. When Oliver runs saccadometry and sees a frontal lobe that isn't working well, he said, that's frequently where the anger or impulsiveness is coming from — which is why he routinely asks a patient's spouse specifically about mood and irritability rather than relying only on the patient's own account, since family members often notice the change first.
He also touched on cranial nerve function connected to the autonomic nervous system, noting that dysautonomia — dysregulation of the body's automatic functions — shows up as a symptom in some post-concussion patients, though he framed it as one piece of a broader picture rather than a stand-alone diagnosis.
Two Exercises Dr. Oliver Recommends
Asked what someone could start doing before ever getting tested, Oliver offered two general exercises. The first, which he calls "slingshot saccades," involves holding your thumbs up at arm's length, focusing on one target, then shifting your eyes and head to the other target and back — a repeated exchange that he said exercises the frontal lobe through fast eye movement. The second is simpler still: gargling. Activating the muscles at the back of the throat, he said, stimulates vagal nerve tone, which supports heart and gut function and, specifically, gut motility. He was clear these are general-purpose exercises, not a treatment plan, and that his actual protocols are built around each patient's specific test results.
The Gut-Brain Connection, Cost, and Access to Care
Oliver framed concussion recovery as a whole-body issue rather than a brain-only one. He cited research showing that many people develop some degree of leaky gut within 30 to 60 minutes of a head injury, and cautioned that gut problems don't always show up as digestive symptoms — they can present as neuropathy, migraines, or vertigo instead. As he put it, referencing the opening line of a well-known anatomy text: "Page one, Gray's Anatomy — the nervous system controls every function in the human body." That's part of why he doesn't isolate treatment to a single system, and why his intake process also includes hormone testing (a dried-urine panel called a Dutch test) and food-sensitivity testing through a lab called Cyrex Laboratories, based in Phoenix.
On cost, Oliver described his practice as largely cash-based, noting the only insurance he works with directly is personal injury coverage. He was candid about his frustration with how insurance handles newer therapies — citing transcranial magnetic stimulation (TMS), which he offers for depression and anxiety, and which insurers typically won't pre-authorize until a patient has tried at least two, and sometimes four, medications first. At the time of the conversation, he described charging around $290 for an initial two-hour evaluation, noting that comparable exams elsewhere can run upward of $2,000, and that a full concussion case — testing, bloodwork, and roughly two months of rehab — has historically landed somewhere in the $2,500 to $4,000 range. He also does periodic telehealth follow-ups for patients who travel to see him in person from out of state, though hands-on chiropractic work itself can't be done remotely. Asked how to vet a doctor generally, he pointed to patient reviews, community word of mouth, and — above all — finding someone willing to take the time to look at the whole body rather than rush a visit.
