Postural orthostatic tachycardia syndrome is one of the most prevalent and persistently mismanaged conditions in clinical practice today. With an estimated 1 to 3 million affected individuals in the United States, the majority presenting as young women aged 12 to 50, POTS arrives in clinical settings carrying a complex web of comorbidities including migraine, hypermobile Ehlers-Danlos syndrome, mast cell activation syndrome, and chronic fatigue. Despite its prevalence, the NIH itself acknowledges that clinical evaluation is not standardized, treatment approaches are inconsistent, and familiarity with the condition across the medical community remains insufficient. For clinicians trained in functional neurology, this is precisely where a deeper understanding of autonomic nervous system physiology becomes a genuine clinical differentiator.

This course transforms the way clinicians approach dysautonomia. Rather than anchoring to a diagnostic label that describes tachycardia without explaining why, this training builds a mechanistic understanding of the entire autonomic circuit. From the final autonomic pathways of the peripheral sympathetic and parasympathetic systems, through baroreflex integration at the level of the NTS, nucleus ambiguus, and RVLM, up to supramedullary command centers<output id="about_this_course">Postural orthostatic tachycardia syndrome is one of the most prevalent and persistently mismanaged conditions in clinical practice today.

This course transforms the way clinicians approach dysautonomia. Rather than anchoring to a diagnostic label that describes tachycardia without explaining why, this training builds a mechanistic understanding of the entire autonomic circuit. From the final autonomic pathways of the peripheral sympathetic and parasympathetic systems, through baroreflex integration at the level of the NTS, nucleus ambiguus, and RVLM, up to supramedullary command centers including the insular cortex, anterior cingulate, amygdala, hypothalamus, and periaqueductal gray, clinicians gain a complete neuroanatomical map of where and how the system breaks down. Autonomic testing is covered in clinical depth, including tilt table test interpretation across multiple orthostatic patterns, heart rate variability analysis, sudomotor assessment, pupillometry, and bedside small fiber neuropathy evaluation using validated tools. Real patient cases with autonomic testing data are integrated throughout to anchor every concept in practice.

This course is designed for licensed clinicians who regularly encounter patients with unexplained dizziness, orthostatic intolerance, fatigue, brain fog, exercise intolerance, or dysautonomia and who want to understand these presentations at a mechanistic level. It is particularly well suited to chiropractic neurologists, functional neurologists, and integrative practitioners seeking a rigorous, testable framework for assessment and non-pharmacological clinical management.

Dr. Nathan Keiser is a chiropractor and chiropractic neurologist with advanced training in functional neurology. Drawing on current autonomic neuroscience literature and real clinical case material, his teaching bridges the gap between laboratory-level neurophysiology and the practical demands of the clinical encounter. This course delivers 15 hours of continuing education credit and is built for clinicians who hold themselves to a high standard of mechanistic reasoning and patient outcomes.
