Brief Summary:
The gut may be a portal of entry for agents that cause or contribute to the causes of Parkinson's disease (PD). The investigators are studying changes in the normal population of gut flora and in intestinal permeability and their associations with early PD.
Detailed Description:
Clinical and pathological data suggest Parkinson's disease (PD) may result from an inflammatory process beginning in the intestinal wall that initiates alpha-synuclein aggregation, which then spreads from neuron to neuron, reaching the central nervous system. Bacteria living within the intestinal tract produce lipopolysaccharide endotoxin, a toxin known to induce parkinsonism in animal models. We hypothesize that exposure to LPS, either from excessive production or excessive absorption may be the cause of this inflammation. This study aims to: (1) describe differences in the population of gut bacteria in PD compared to control subjects; (2) assess leakiness of the gut wall by differential absorption of non-absorbable sugars; (3) measure plasma levels of endotoxin and inflammation; and (4) study characteristic PD pathology and evidence of inflammation in biopsy samples of the colon obtained by sigmoidoscopy.
