What’s Actually Happening in the Nervous System During Dysautonomia?

Brain Communication and POTS Postural Orthostatic Tachycardia Syndrome (POTS) is one of the most misunderstood nervous system conditions today. It’s part of a larger group of disorders known as dysautonomia, where the autonomic nervous system (ANS) doesn’t function correctly. The ANS controls automatic body processes like heart rate, blood pressure, digestion, and temperature regulation. When it’s out of sync, the body feels chaotic—especially when changing positions like standing up. POTS symptoms often include: Fast heart rate when standing Dizziness or fainting Brain fog Fatigue Temperature regulation issues Shaky or anxious feelings Many patients are told it’s “just anxiety” or are bounced from doctor to doctor without answers. But the issue is real—and it’s often rooted in how the brain and body communicate. The Three Subtypes of POTS There are three common subtypes of POTS, each with its own pattern: Hyperadrenergic POTS- This type involves too much adrenaline. When standing, people may feel like they’re in constant fight-or-flight mode: fast heartbeat, high blood pressure, sweating, and panic-like symptoms. Neuropathic POTS- This subtype results from poor nerve function, especially in the legs. The small nerves that control blood vessels don’t squeeze properly, so blood pools in the lower body. That means less blood gets to the brain—causing dizziness, blurry vision, or blue hands and feet. Hypovolemic POTS- Here, the total blood volume is too low. That could be due to problems with fluid retention, salt balance, or kidney function. People may feel lightheaded, weak, and intolerant to heat or exercise. Many patients actually have a mix of these subtypes, which is why personalized care is so important. Where Upper Cervical Care Comes In  At the very top of your spine is the craniocervical junction (CCJ)—the area where the skull meets the top two bones in your neck (the atlas and axis). This region surrounds the brainstem, which acts as the body’s autopilot control center. It helps regulate: Blood pressure Heart rate Breathing rhythm Vagal tone (rest-and-digest) Adrenal and kidney signaling Blood vessel control When the CCJ is misaligned—even by a few millimeters—it can distort neurologic input and blood flow to the brainstem. Think of it like a blown fuse at the breaker box: the system isn’t completely shut down, but nothing is working quite right. Upper cervical care gently corrects these misalignments, allowing the nervous system to regulate more effectively. Many POTS patients experience reduced symptoms like fewer dizzy spells, steadier heart rate, and improved mental clarity after care begins. Subtype Support: A Functional Comparison Here’s how upper cervical care may help across all three POTS subtypes:

Pain, Throbbing, Aching, Pressure, and Tension In The Head Dysautonomia isn’t a single condition—it’s a term that describes a range of disorders affecting the autonomic nervous system (ANS), which regulates things like heart rate, digestion, and blood pressure. For many patients, the search for answers becomes a long, exhausting journey. Why? Because our healthcare system isn't built to see the whole picture. A Medical Maze with No Map Most patients are referred from specialist to specialist—cardiology, neurology, psychiatry, gastroenterology—depending on their most prominent symptoms. A person with dizziness might see a heart doctor. Another with brain fog or headaches might land in a neurologist’s office. Yet, none of these specialties receive in-depth training in autonomic function. Each only sees a piece of the puzzle, often missing the bigger neurologic pattern underneath. That leads to fragmented testing, vague labels, and treatments that aim to manage symptoms—without addressing what’s disrupting communication between the brain and the body. Why It’s So Complex Dysautonomia is a multi-system issue. The heart, lungs, digestion, balance, and even emotional regulation are often affected all at once. And while symptoms vary from person to person, many cases seem to stem from similar root factors: physical trauma, infections, emotional stress, or genetic predisposition. These disrupt the circuits governed by the brainstem and vagus nerve—key players in automatic body function. The challenge? These root causes don’t always show up on standard bloodwork or imaging. That’s why a patient might be told “everything looks normal,” even when their daily function is clearly impaired. A Shortage of Help Navigating dysautonomia isn’t just hard for patients—it’s also tough for clinicians. Testing is complicated, terminology can be confusing, and the disorder lives in a gray zone between physical and mental health. There are far more patients needing help than providers equipped to deliver it. So What Can Be Done? It starts with clarity—both for the patient and the care team. At Cerebral Chiropractic, we approach these cases by asking, “What could be interfering with the nervous system’s ability to self-regulate?” We believe the body was designed to heal—and that healing becomes more possible when the pathways between brain and body are clear.

This case study reports on a 15-year-old boy with daily headaches and chronic migraines that improved dramatically under Kale upper cervical care. After two years, migraines dropped from once every 3 weeks to only 5 total episodes. Upper cervical care may be a safe, effective option for adolescents with migraines.

This case report describes a 53-year-old patient with 12 years of migraines who experienced full symptom resolution through Atlas Orthogonal care. Precision X-ray analysis and vector-guided atlas correction resulted in immediate and lasting relief from migraine, neck pain, and neurological symptoms.

This article highlights the use of cone-beam CT to assess upper cervical misalignment in a migraine patient. Guided by Blair protocol, two atlas corrections over 10 weeks led to reduced pain and medication use. Upper cervical care continues to advance through precision imaging and individualized correction.

Drs. Bernard, Alcantara, and Pierce report on a 16-year-old with lifelong migraines who found relief through Advanced Orthogonal upper cervical care. After years of medications and ER visits, precise atlas correction dramatically reduced her symptoms and improved quality of life.

Dr. Robert Trager and colleagues present a case where upper cervical chiropractic care played a key role in resolving chronic dizziness linked to cervicogenic dizziness, upper cervical instability, and POTS. The patient improved significantly through conservative management including manual therapy, stability exercises, and autonomic support.

Dr. G. Dave Singh, Dr. Chris Chapman, and Dr. Myles Preble demonstrated that combining upper cervical chiropractic care with biomimetic oral appliance therapy can significantly improve craniofacial alignment. The study highlights how integrating these therapies enhances structural stability and supports neurological health through a multidisciplinary approach.

Dr. Woodfield and his colleagues conducted a groundbreaking study showing how atlas realignment may reduce migraine days and improve quality of life. The research highlights the potential of precise upper cervical care to address migraines at their root, offering insights into a non-invasive approach that could transform migraine management.
