Where does Parkinson's disease start: In the brain, gut, or both?


Does Parkinson’s disease (PD) start in the brain or the gut? In a new contribution published in the Journal of Parkinson’s Disease, scientists hypothesize that PD can be divided into two subtypes: gut-first, originating in the peripheral nervous system (PNS) of the gut and spreading to the brain; and brain-first, originating in the brain, or entering the brain via the olfactory system, and spreading to the brainstem and peripheral nervous system.
