Brain, Cognition & Longevity
Brain, Cognition & Longevity examines how oral health may intersect with cognitive decline and brain aging. Across ten presentations, the course explores inflammatory, vascular, microbial, sleep-related, and aging pathways while distinguishing established evidence from association, early signal, and unresolved questions. The emphasis is on accurate interpretation, careful communication, and clinically useful action across medical and dental settings.

Course Overview
What this course covers
Brain, Cognition & Longevity examines how oral health may intersect with cognitive decline and brain aging. Across ten presentations, the course explores inflammatory, vascular, microbial, sleep-related, and aging pathways while distinguishing established evidence from association, early signal, and unresolved questions. The emphasis is on accurate interpretation, careful communication, and clinically useful action across medical and dental settings.
Curriculum
Presentations Included
P. gingivalis and the Alzheimer’s Mechanistic Case
Uses the Alzheimer mechanistic literature to separate biological plausibility, tissue findings, association, and the much harder question of human causation.
Tooth Loss, Chewing and Cognition
Examines associations among tooth loss, masticatory function, nutrition, vascular risk, and cognitive outcomes while keeping reverse causation and confounding visible.
Sleep, Glymphatic Clearance and the Brain
Explores deep sleep, perivascular and glymphatic clearance, and why airway and sleep findings matter in a course about cognition without overstating what the pathway proves.
Parkinson’s Disease, Depression and the Mouth
Reviews oral findings seen with Parkinson’s disease and depression and emphasizes directionality, medication effects, self-care limitations, and the risk of reading consequence as cause.
Stroke, Small Vessels and Blood Pressure: The Vascular Route to Cognitive Decline
Connects hypertension, cerebral small-vessel disease, stroke, and cognitive decline and identifies practical opportunities for recognition and referral across healthcare settings.
Inflammaging: The Background Fire of Aging
Introduces chronic age-related inflammatory signaling and how immune aging can create a biologic environment in which local inflammatory burdens matter more.
The Cellular Machinery of Aging
Examines cellular senescence, immune signaling, mitochondrial and tissue-level aging mechanisms that help explain how chronic inflammatory exposures can become self-sustaining.
The Mouth as an Inflammaging Accelerator
Tests the accelerator claim against human evidence: whether periodontal inflammation raises systemic inflammatory tone, whether treatment lowers it, whether oral status tracks with biological aging, and where causality remains unresolved.
Biological Age: When the Number Is Less Certain Than It Looks
Examines biological-age clocks and emerging biomarkers, what they measure, how precise they really are, and how clinicians should communicate results without converting an estimate into a diagnosis.
Learning Outcomes
Learning Objectives
Upon completion of this course, participants should be able to:
- Describe the principal biological routes through which oral organisms, bacterial products, and inflammatory signals may reach or influence the brain.
- Distinguish oral-brain association from evidence of causation.
- Summarize the evidence linking periodontal disease, oral microbial findings, and Alzheimer’s disease without overstating what has been established.
- Explain how tooth loss and reduced chewing function may relate to cognition and identify the limits of that evidence.
- Describe the vascular contribution to cognitive impairment and the role of blood pressure and cerebral small-vessel injury.
- Explain the relationship among sleep, deep-sleep physiology, perivascular pathways, and overnight brain clearance at the appropriate evidence strength.
- Describe oral findings associated with Parkinson’s disease and depression, including where directionality remains uncertain.
- Explain how chronic inflammation, immune aging, cellular senescence, and related aging biology may influence oral and neurological health.
- Evaluate biological-age and biomarker claims critically.
- Translate oral findings into scope-appropriate clinical action and interdisciplinary communication without promising neurological prevention that has not been demonstrated.
