Earlier than we dive into these findings, let’s cowl the present state of Parkinson’s analysis, previous this research.
The most typical suspected explanation for 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 inside the partitions of the GI tract, 2extending from the esophagus to the anal canal, in individuals with Parkinson’s illness.
The brand new research, revealed in BMJ Journals got down to discover the potential of Parkinson’s illness originating within the intestine, based mostly on the truth that misfolded proteins have been discovered within the GI tract and esophagus.
In an effort to research this, researchers seemed for Parkinson’s sufferers who had digestive signs earlier than being recognized with the mind dysfunction.
The researchers analyzed a mixture of case-control research of 24,624 Parkinson’s sufferers and a cohort research 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.
