Why Multi-Factorial Secondary Dysautonomia is Often the Last Diagnosis Considered: Barriers, Biases, and Clinical Implications
Author(s): Bruce H. Knox*
Multi-factorial secondary dysautonomia represents a clinically significant but under-recognised category within autonomic medicine. Despite extensive evidence that autonomic dysfunction may arise from cumulative and interacting insults—including immune, infectious, metabolic, and iatrogenic factors—this diagnosis is frequently considered only after neurodegenerative and primary autonomic disorders have been excluded. This paper examines why multi-factorial secondary dysautonomia is often the last diagnosis entertained, identifying key barriers including diagnostic frameworks based on single-cause models, limitations in testing modalities, cognitive bias, and structural fragmentation in healthcare systems. Using a longitudinal case characterised by severe autonomic collapse followed by recovery, this paper highlights the clinical and conceptual advantages of recognising mul.. Read More»
