Where does Parkinson’s disease start? In the brain or gut? Or both?

Lewy body disorders, including Parkinson's disease and Lewy body dementia, comprise of two distinct subtypes. One subtype originates in the peripheral nervous system (PNS) of the gut and spreads to the brain. The other originates in the brain, or enters the brain via the olfactory system, before spreading to the brainstem and PNS.

The Neural Pathways for Vomiting After Eating Infected Food

After eating contaminated food, toxins activate the release of serotonin by the enterochromaffin cells on the lining of the intestinal lumen. The serotonin binds to receptors on vagal sensory neurons in the gut, transmitting signals along the vagus nerve to neurons in the dorsal vagal complex, inducing retching behaviors.

Microbial Based Treatment Reverses ASD’s Social Deficits: Mouse Study

Researchers report the administration of Lactobacillus reuteri may lead to brain changes that reverse social deficits in mouse models of ASD through a mechanism that involves the vagus nerve and reward system. The findings hold promise for the development of treatments for ASD, as well as other disorders, by modulating specific gut microbes.

Inflamed monkey guts produce Parkinson’s-related proteins

Inflammation of the colon is associated with alterations in alpha-synuclein expression and phosphorylation in the myenteric plexus of common marmoset monkeys. The findings support the growing body of evidence that inflammation may play a role in the development of Parkinson's disease.
