Publications & Research
Dr. Pappolla is a physician-scientist whose clinical practice is grounded in original research. With 123 peer-reviewed publications in leading medical journals, his work has shaped the understanding of Alzheimer's disease, central pain, and neurological aging.
Core Research Areas
Dr. Pappolla's research spans three interconnected areas that directly inform his clinical practice in Houston.
Alzheimer's Disease
Dr. Pappolla was the first to propose a role for melatonin in Alzheimer's disease and among the first to demonstrate that cholesterol and insulin resistance are modifiable risk factors. His work on amyloid clearance via the lymphatic system has directly shaped current treatment research.
Biomarkers & AI Diagnostics
Pioneering research applying artificial intelligence to blood serum metabolic biomarkers for early Alzheimer's detection. This work represents the frontier of non-invasive neurological diagnostics and has significant implications for early intervention.
Central Pain & Insulin Resistance
Dr. Pappolla was the first to demonstrate a link between insulin resistance and central pain — a form of chronic pain originating in the brain itself due to measurable structural and biochemical changes in the nervous system, not injury to muscles or joints.

Like many physician-researchers who have dedicated their careers to advancing our understanding of neurological disease, Dr. Pappolla has contributed to the scientific literature that informs clinical practice. When you see him as a patient, you benefit from a physician who has worked alongside that research firsthand — not just read about it.
This is especially meaningful for patients with complex conditions like TBI, post-concussion syndrome, Alzheimer's disease, and treatment-resistant chronic pain — conditions where standard protocols often fall short and a deeper understanding of the underlying biology makes a real difference.
