Enteric α-synuclein misfolding spreads retrogradely via vagal afferents to DMV, then progressively to SNc (Braak stages III-VI). While anatomically compelling, the central assumption that enteric pathology is the initiating event is contested. Overexpression artifacts dominate animal models; vagotomy protection is inconsistently replicated. Best therapeutic strategy: transcutaneous vagus nerve stimulation (t-VNS) for desynchronization rather than blocking physical propagation.
PD patients exhibit dual ENS pathology: α-synuclein aggregation within enteric neurons and progressive loss of cholinergic/nitrergic neurons. This disrupts gut motility causing constipation, SIBO, and dysbiosis blooms (H. pylori, Klebsiella). Enteric glial reactivity and S100B release complete a feedforward inflammatory loop. Clinical observations are robust; the primary weakness is circular logic regarding initiating event. Gut-directed therapies (prokinetics, H. pylori eradication, FMT) may br
