Earlier than we dive into these findings, let’s cowl the present state of Parkinson’s analysis, previous this examine.
The most typical suspected reason behind Parkinson’s illness is a pathological sample of Lewy physique (LB) protein deposition. These depositions, researchers say, primarily encompass misfolded α-synuclein—a presynaptic neuronal protein that’s linked genetically and neuropathologically to Parkinson’s illness1.
Apparently, the misfolded α-synuclein has not solely been discovered within the central nervous system but in addition within the vagus nerve and the enteric nervous system (ENS)—the latter positioned throughout the partitions of the GI tract, 2extending from the esophagus to the anal canal, in folks with Parkinson’s illness.
The brand new examine, printed in BMJ Journals got down to discover the potential of Parkinson’s illness originating within the intestine, primarily based on the truth that misfolded proteins have been discovered within the GI tract and esophagus.
With a view to examine this, researchers seemed for Parkinson’s sufferers who had digestive signs earlier than being recognized with the mind dysfunction.
The researchers analyzed a mix of case-control research of 24,624 Parkinson’s sufferers and a cohort examine using a US-based nationwide medical document community. They seemed for a broad vary of each GI signs and GI diagnoses that appeared earlier than Parkinson’s diagnoses.
