Clinical neurochemistry and functional medicine practitioners working with neurologically complex patients increasingly encounter a consistent pattern: neurological rehabilitation stalls, symptoms relapse, and standard workups come back unremarkable. The emerging body of evidence in gut immunology, microbiota-gut-brain axis research, and autoimmune neurology makes clear that metabolic and immunological barriers are often the rate-limiting factor in clinical outcomes. This module addresses that gap directly.

Module 4 of the Clinical Neurochemistry and Nutrition series builds on foundational neurochemical principles to deliver a clinically actionable framework for evaluating and managing the gut-immune-brain interface. Core topics include the innate and adaptive immune system, intestinal barrier physiology and tight junction regulation, the microbiota-gut-brain-immune axis, autoimmunity mechanisms including molecular mimicry and oral tolerance failure, white blood cell differential interpretation, CRP and Vitamin D as clinical markers, and the neurochemical priorities framework that guides case sequencing. Functional lab interpretation, including Cyrex Array 5 antibody panels, blood chemistry optimization, and HPA axis assessment, is integrated throughout.

This course is designed for licensed healthcare clinicians including chiropractors, chiropractic neurologists, functional medicine practitioners, naturopathic physicians, and other advanced clinicians who already possess a working knowledge of neurophysiology and are ready to integrate immunological and nutritional case management into their clinical decision-making. It is particularly valuable for practitioners who see patients with autoimmune diagnoses, treatment-resistant neurological presentations, or complex multi-system complaints that have not responded to conventional or standard functional approaches.

Dr. David Clark, DC, brings a rare combination of credentials to this content. A Fellow of the American College of Functional Neurology, Fellow of the American Board of Brain Injury and Rehabilitation, Diplomate of the American Chiropractic Neurology Board, Diplomate of the College of Clinical Nutrition, and Vestibular Rehabilitation Specialist, Dr. Clark draws on decades of clinical experience and an exhaustive reference library spanning neurochemistry, immunology, gastroenterology, and functional medicine. His teaching is distinguished by case-driven rigor, clinical honesty, and a commitment to reasoning over protocol.
