Brain-Gut Insights: SIBO, Gut Motility, and Sustained Brain Support

Dr. Manna Semby, ND

Dr. Manna Semby is passionate about midlife women and their quality of life—because midlife is the inflection point for brain health. It’s when hormones shift, risks accelerate, and the window for meaningful prevention is wide open. A former Goldman Sachs vice president, Dr. Manna brings a rigorous, analytical process to care: clarify the goal, map the variables, test the levers, measure the outcome.

Her work spans optimizing wellness for pre-, peri-, and post-menopausal women and advancing a practical framework she calls the Brain-Risk Burden—the combined impact of medications, supplements, sleep, metabolism, and the gut–brain axis on cognition. She translates complex science into clear, doable plans that help women live fully and think clearly for decades to come.

Dr. Manna is a graduate of Bastyr University, San Diego, and a Menopause Society, IFM, and ReCODE 2.0 Certified Practitioner. Her mission is simple and bold: help women prevent dementia

The Brain-Risk Burden: How Drugs & Supplements Affect Cognition via the Gut–Brain–Metabolism Axis

Dr. Amy Rolfsen, ND

Dr. Amy Rolfsen is a naturopathic physician with a clinical and consulting practice focused on neuroimmunology, gut-immune dysfunction, and complex inflammatory conditions affecting cognition, mood, and behaviour. Her work centers on individuals experiencing neurodivergent presentations—such as ADHD, autism spectrum conditions, OCD, and tics—often accompanied by gastrointestinal symptoms, immune dysregulation, or environmentally triggered flares.

In addition to clinical care, Dr. Rolfsen provides peer consultation for clinicians working through complex cases involving functional testing and integrative protocols. She also contributes to ongoing education and research initiatives exploring the gut-brain-immune axis.

With a practical, systems-based lens, she helps clinicians recognize immune and inflammatory drivers behind neuropsychiatric symptoms—translating emerging science into meaningful strategies for care.
