Brain Injury
Chiropractic care may help brain injury survivors by reducing spinal cord tension and enhancing cerebrospinal fluid dynamics. Adjustments support reorganization of sensory-motor maps and autonomic balance, promoting faster and more coherent healing. Many case reports describe improvements in headaches, cognition, and mood in post-concussion or TBI patients.

Many case reports describe improvements in headaches, cognition, and mood in post-concussion or TBI patients, suggesting chiropractic as a promising complementary approach.
Spinal Cord Tension and the Dentate Ligament Theory
After a traumatic brain injury (TBI) or concussion, subtle misalignments in the spine can place adverse mechanical tension on the spinal cord. In chiropractic theory, this is often attributed to the dentate ligament–cord distortion hypothesis pmc.ncbi.nlm.nih.gov. The dentate ligaments are small but strong bands of connective tissue that anchor the spinal cord to the vertebrae inside the spinal canal. When the top cervical vertebrae (the atlas C1 or axis C2) are misaligned even slightly, these ligaments can tug on the spinal cord, mechanically irritating and deforming the cord pmc.ncbi.nlm.nih.gov. An atlas or axis subluxation may exert a direct physical stress on the brainstem and upper spinal cord, contributing towards nervous system dysregulation. This tension is theorized to interfere with normal nerve signal transmission, altering the tone of the nervous system by keeping it in a heightened state of stress or irritation.
Chiropractic adjustments of the upper cervical spine aim to gently realign the atlas and axis, thereby releasing this tension. By correcting the subluxation, the abnormal drag on the cord via the dentate ligaments is relieved. This can have profound effects on the patient’s nervous system. Reducing adverse cord tension may allow the neural pathways to function with less irritation, potentially calming an overactive fight-or-flight response and restoring a healthier balance to the nervous system’s activity. In fact, the original developer of the dentate ligament theory built upon earlier neurological research (notably by neurosurgeon Alf Breig) on how persistent cord stress can impair nervous system function pmc.ncbi.nlm.nih.gov. The practical implication is that a chiropractor adjusting the spine may help a brain-injured individual by literally taking pressure off the spinal cord, giving the brain and nerves a chance to operate more efficiently. This can set the stage for better healing: nerve signals between the brain and body flow more freely once tension is removed. Many patients and clinicians report that after specific adjustments, patients exhibit signs of reduced neural tension, less muscle spasticity, smoother movement, and even a calmer demeanor. Chiropractic is the ultimate form of nervous system regulation.
Enhancing Cerebrospinal Fluid (CSF) Dynamics with Chiropractic
Proper cerebrospinal fluid flow is crucial for brain health and recovery after injury. CSF circulates around the brain and spinal cord, providing cushioning, removing metabolic waste, and delivering nutrients. After head or neck trauma, however, the normal circulation of CSF can be disrupted. Swelling, inflammation, or subtle shifts in cranial and cervical alignment may lead to CSF bottlenecks or stagnation. This is significant because stagnant or obstructed CSF flow can increase intracranial pressure and impede the brain’s waste clearance mechanisms, exacerbating post-concussive symptoms like headaches and cognitive fog.
Chiropractic care has shown promise in improving CSF dynamics. Misalignment in the upper neck has been associated with CSF “stasis,” meaning the fluid isn’t moving as it should topchiropractic.co.uk. One model suggests that a misaligned atlas can partly kink or compress the narrow passageways where CSF exits the skull, leading to fluid back-up. This situation has been observed in advanced upright MRI studies. Notably, research using cinematic MRI scans by Dr. Scott Rosa and colleagues demonstrated that before an atlas correction, CSF flow can be irregular or impeded, whereas after a specific upper cervical chiropractic adjustment, CSF velocity and flow become more uniform topchiropractic.co.uk. In one such study, pre- and post-adjustment MRI scans were compared: following the chiropractic correction, the CSF flow was seen to stabilize and resume a normal rhythm, which facilitates proper drainage of toxins and delivery of nutrients in the brain topchiropractic.co.uk.
These findings align with clinical observations in conditions like multiple sclerosis, which some researchers believe can be aggravated by CSF flow abnormalities. A 2011 imaging study by Dr. Raymond Damadian (the inventor of MRI) found that patients with MS often had a history of head or neck trauma and showed visible obstructions of CSF flow on upright MRI topchiropractic.co.uk. The obstructions were associated with increased intracranial pressure and “leakage” of fluid into brain tissue, potentially causing lesions. Importantly, when those patients received gentle upper cervical adjustments, follow-up imaging showed improved CSF circulation and reductions in those pressure indicators.
For brain injury survivors, the key takeaway is that chiropractic adjustments may help restore proper fluid dynamics around the brain and cord. By realigning the neck and reducing any subtle compressive forces on the cranio-cervical junction, chiropractic care can reopen the natural pathways for CSF flow. Patients often report relief from pressure-type headaches and clearer thinking after upper cervical adjustments. This corresponds with the idea that intracranial pressure has been lowered and the brain is better “bathed” by its nourishing fluid after an adjustment. Healthy CSF flow means the brain can more effectively wash out the inflammatory byproducts of injury and get the nutrients it needs for recovery. This physiologic boost, combined with reduced mechanical cord tension, creates an internal environment more conducive to healing and neuroplasticity.
Neuroplastic Reorganization of Sensory-Motor Function with Chiropractic
One of the most exciting aspects of chiropractic care in the context of brain injuries is its potential to assist in neuroplasticity: the brain’s ability to reorganize and heal its neural networks. Traumatic brain injuries often disrupt normal communication between the body’s sensory systems and the brain’s processing centers. For example, concussed patients frequently suffer problems with balance, coordination, vision, and proprioception (body awareness), as well as cognitive difficulties. These issues stem from disorganized sensory-motor integration in the central nervous system. The brain may have trouble integrating signals from the eyes, inner ear, and neck muscles, leading to dizziness, visual disturbances, or clumsy motor control. Growing evidence suggests that spinal adjustments can produce measurable changes in the brain’s sensory-motor processing, essentially helping the brain “reset” or re-map itself more correctly. Chiropractic researchers have utilized techniques like electroencephalography (EEG) and functional MRI to study brain activity before and after spinal adjustments. In one notable study, a single session of chiropractic in subjects with neck dysfunction led to significant changes in somatosensory evoked potentials in the brain’s cortex pmc.ncbi.nlm.nih.gov. The adjustment produced a 16-20% reduction in certain EEG signal amplitudes associated with the prefrontal cortex, indicating that the brain modulated its processing of sensory input after the chiropractic intervention pmc.ncbi.nlm.nih.gov. The authors concluded that a chiropractic adjustment can alter somatosensory processing at the cortical level, particularly in areas involved in executive function and motor control pmc.ncbi.nlm.nih.gov.
Chiropractic care may help the injured brain form new, healthier connections by providing afferent input that the brain can use to rewire itself. Each spinal adjustment sends a burst of sensory information up the spinal cord to the brain. When that input comes from a properly aligned and moving spine, the brain receives clear, coherent signals about the body’s position and movement. This can stimulate neuroplastic responses where the brain starts adjusting its signaling pathways to better match the realigned body. Over time, this may support reorganization of the brain’s sensory and motor maps that were thrown off by the injury. Patients often report functional improvements such as steadier balance, sharper coordination, and even cognitive clarity after a period of chiropractic care. These subjective improvements are backed by objective studies showing that chiropractic adjustments can enhance reflexes, joint position sense, and even cortical brain processing efficiency journal.parker.edupmc.ncbi.nlm.nih.gov. In short, chiropractic care can act as a catalyst for the brain’s innate healing processes, helping it find its way back to normal function through neuroplastic change.
Restoring Autonomic Balance and Tone with Chiropractic
Beyond just sensory-motor benefits, chiropractic adjustments may also help rebalance the autonomic nervous system, which is often dysregulated after brain trauma. The autonomic nervous system controls our unconscious functions like heart rate, blood pressure, digestion, pupil dilation, and more. The nervous system has two primary modes: sympathetic (fight or flight) and parasympathetic (rest and digest). Many TBI and post-concussion patients live in a state of sympathetic dominance, meaning the stress-response branch overshadows the calming branch. This can manifest as elevated heart rate and blood pressure, poor sleep, anxiety, light sensitivity, digestive issues, and general difficulty relaxing: all common complaints after concussions cognitivefxusa.com. An overactive sympathetic tone can hinder recovery by impairing sleep and regeneration, so finding ways to shift the body back toward parasympathetic balance is critical.
Chiropractic care has demonstrated the ability to influence autonomic function, likely through its impact on the spinal cord and brainstem centers that regulate autonomic outflow. When adverse mechanical cord tension is relieved, and spinal joint receptors send healthy signals, the autonomic system can recalibrate. A dramatic example comes from a pilot randomized trial on hypertension: patients with high blood pressure and misaligned C1 vertebrae received a single precise upper cervical adjustment. The result was an average 17 point drop in systolic blood pressure in the adjusted group, compared to only a 3 point drop in the sham (placebo) group pubmed.ncbi.nlm.nih.gov. Diastolic blood pressure likewise fell ~10 points in the adjusted patients, vs. ~2 points in controls pubmed.ncbi.nlm.nih.gov. These improvements lasted for weeks. Remarkably, the lead author (a medical hypertension specialist) noted that this effect was equivalent to giving two blood-pressure medications simultaneously pubmed.ncbi.nlm.nih.gov. This study concluded that restoring atlas alignment had a profound, sustained effect on autonomic regulation of blood pressure, achieved without any drugs. The chiropractic adjustment influenced central neural circuits in the brainstem that control cardiovascular tone.
For a brain-injured individual, these implications are encouraging. Upper cervical misalignments which can occur due to whiplash or head impact might contribute to dysautonomia by irritating the brainstem (where the vagus nerve and other autonomic nuclei reside) cognitivefxusa.com. By correcting those misalignments, chiropractic may help reduce the sympathetic overdrive and allow parasympathetic (calming) activity to increase. Patients often report seemingly unrelated improvements under chiropractic care that actually point to autonomic balancing. For example: better sleep patterns, improved digestion, more stable moods, and less anxiety are common anecdotal reports from patients following chiropractic care. These reflect a shift out of chronic “fight or flight.” Indeed, preliminary research using heart rate variability (HRV), a measure of autonomic balance, shows that chiropractic adjustments tend to increase HRV, indicating a healthier balance between sympathetic and parasympathetic tone pubmed.ncbi.nlm.nih.gov.
In summary, chiropractic adjustments can patients with TBI help reset the autonomic nervous system to a more balanced state. This is critically important in brain injury recovery, as a balanced autonomic state promotes immune function, restorative sleep, and tissue healing. By addressing both the structural spinal issues and the neurological tone, chiropractic care uniquely targets an often overlooked aspect of TBI rehabilitation: it’s not just about healing the brain’s cells, but also about normalizing the environment like blood flow, CSF flow, neural tone in which the brain operates.
Case Studies: Improvements in TBI and Concussion Symptoms
While large-scale clinical trials on chiropractic for brain injuries are still forthcoming, numerous case reports and small studies have documented notable improvements in TBI and post-concussion syndrome patients under chiropractic care. These cases, published in peer-reviewed journals, provide compelling real-world examples of what is possible:
Pediatric Concussions and Chiropractic
One case involved a 13-year-old boy who had persistent post-concussion symptoms after a sports injury. He suffered from daily headaches, poor concentration in school, and severe light sensitivity (photophobia). After a thorough evaluation, a chiropractor provided care twice a week, including upper cervical specific adjustments and full-spine adjustments as needed. After four weeks (eight visits), the boy showed 80% overall improvement in his symptoms, with significant reductions in headache intensity, improved attention span, and resolution of photophobia jccponline.com. By the re-examination, his neurological exam had normalized and he was able to return to regular activities. The authors concluded this case illustrates how concussion-related headaches and cognitive symptoms may improve in patients receiving chiropractic care jccponline.com
Chiropractic for Post-Concussion Syndrome
A 14-year-old male hockey player suffered a concussion and, despite standard medical management, continued to experience an occipital headache rated 8/10 in pain, dizziness, mental fog, memory trouble, and fatigue for nearly two weeks with no improvement pubmed.ncbi.nlm.nih.gov. In a case report published in the Journal of Chiropractic Medicine, chiropractors took a multidisciplinary approach focusing on the cervical spine. They delivered gentle cervical and thoracic adjustments, myofascial release therapy for tight neck muscles, and rehabilitative exercises over the course of five treatments pubmed.ncbi.nlm.nih.gov. Impressively, after this regimen, the patient’s symptoms abated and his neurocognitive test scores (ImPACT concussion testing) improved to normal ranges pubmed.ncbi.nlm.nih.gov. He was cleared to resume playing hockey, having effectively recovered faster than expected given his lack of progress before chiropractic. This case demonstrates how a tailored chiropractic management plan can help break the logjam of post-concussion syndrome, resolving chronic symptoms and restoring function. It is also important to note how chiropractic can work effectively in conjunction with other healing modalities without side effects.
Brain injuries can also aggravate pre-existing conditions. A 23-year-old female patient had a long history of tension headaches, but after a slip-and-fall concussion, she also developed severe positional vertigo (dizziness when changing head positions) vertebralsubluxationresearch.com. Medical exams found no fracture, but she did have a notable upper cervical misalignment on X-ray. She sought upper cervical chiropractic care. Using the Atlas Orthogonal technique (a specific, gentle adjustment to realign the atlas), the chiropractor corrected her C1 subluxation over a series of visits vertebralsubluxationresearch.com. The outcomes were excellent. Her vertigo episodes ceased and her chronic headaches greatly diminished. The clinical report notes that upper cervical specific adjustments were beneficial for this patient’s vertigo, headaches, and post-concussion syndrome vertebralsubluxationresearch.com. By focusing on the craniocervical junction, the chiropractor alleviated the neurological stress causing her debilitating dizziness. This case underscores the importance of evaluating the upper neck in any post-TBI patient with headaches or balance issues.
In a published case series, Olson et al. reported on three young rugby players with concussion histories who underwent chiropractic care. All three had persistent symptoms like headaches and poor concentration. Chiropractic treatments were provided and all three athletes reported notable improvements journal.parker.edu. In one of these cases, a follow-up years later showed the athlete maintained normal function and had no further concussion complications pubmed.ncbi.nlm.nih.gov. Although these are individual cases, the consistency of improvement especially in headaches, cognitive clarity, balance, and mood across reports is encouraging.
It’s important to note that such case studies, while positive, are not “proof” in the way a large clinical trial would be. However, they do offer proof of concept that correcting spinal subluxation can correlate with meaningful recovery in TBI patients. A review of the literature finds that growing numbers of case reports document improvement in post-concussion symptoms following chiropractic adjustments journal.parker.edu. Even in pediatric populations where concussion can be particularly disruptive to development, chiropractic interventions have shown similar improvements without adverse events journal.parker.edupubmed.ncbi.nlm.nih.gov. These reports collectively describe improvements in headache frequency and intensity, neck pain, dizziness, balance, focus and memory, sleep quality, and even emotional stability. For family members seeking hope, this body of qualitative evidence suggests that chiropractic care can offer a gentle, drug-free avenue to support a brain-injured loved one’s recovery in ways conventional care might overlook.
In the journey of brain injury recovery, chiropractic offers a safe and scientifically plausible method to boost the body’s natural healing capacity. It aligns the physical structure to support the delicate brain tissue. With published reports of post-concussion patients regaining their lives after chiropractic care, there is both hope and rationale that your family member could likewise benefit. From normalized blood pressure and neurological tests to resolved headaches and improved cognition, seeking chiropractic care for a loved one with brain injury issues is an incredible choice. It addresses the often-overlooked spine-brain connection, potentially turning a recovery plateau into new progress. And at the very least, it will ensure that the nervous system is well regulated.
