WHY IT MATTERS: Patients and caregivers exploring cannabinoid options for neurological conditions should understand that while the basic science is genuinely promising, the gap between preclinical findings and proven clinical treatments means these approaches are best pursued under informed medical guidance rather than based on headlines alone. CLINICAL OVERVIEW: The endocannabinoid system plays a fundamental role in regulating neuronal health, modulating inflammation, oxidative stress, and cell survival pathways that are central to neurodegenerative disease processes. Non-psychoactive cannabinoids such as CBD, CBG, and CBDV interact with receptors and signaling cascades throughout the central nervous system in ways that may slow or interrupt the progression of conditions like Alzheimer’s disease, Parkinson’s disease, and traumatic brain injury sequelae.
