Understanding Long COVID: How a Viral Illness Can Become a Disorder of Neurovascular Dysfunction, Impaired Recovery and Loss of Physiological Reserve
Dr Graham Exelby 2026 About This Paper This document is a simplified companion to a series of more detailed scientific papers exploring Long COVID, POTS, ME/CFS and related disorders. The formal papers examine the underlying biology in depth, including neurovascular dysfunction, pericyte biology, autonomic regulation, inflammatory signalling, metabolism, recovery physiology and the renin–angiotensin–aldosterone system (RAAS). While these concepts are important, the scientific

Hashimoto's Thyroiditis, Thyroid Nodules and Cervical Drainage DysfunctionA Neurovascular–Lymphatic Model of Thyroid Inflammatory Persistence
Dr Graham Exelby 2026 Abstract Hashimoto's thyroiditis and thyroid nodules are traditionally viewed as manifestations of autoimmune and endocrine disease arising from genetic susceptibility, environmental triggers, loss of immune tolerance, thyroid autoantibody production, and progressive glandular dysfunction. While these mechanisms remain central to disease pathogenesis, they incompletely incorporate the regional venous and lymphatic anatomy upon which normal thyroid physio
