Abstract
Background:
Delayed gastric emptying is a non‐motor symptom of Parkinson's disease. Few data exist on gastric emptying in early‐stage Parkinson's disease. In idiopathic rapid‐eye‐movement sleep behavior disorder, a presumable pre‐motor stage of Parkinson's disease, gastric emptying has not yet been investigated.
Methods:
Twenty healthy controls, 13 patients with idiopathic rapid‐eye‐movement sleep behavior disorder, and 39 patients with Parkinson's disease patients underwent standardized testing for gastric emptying with the ^13^C‐octanoate breath test.
Results:
Gastric emptying was significantly delayed in drug‐naïve (P < .001) and in treated Parkinson's disease patients (P < .001), but normal in patients with idiopathic rapid‐eye‐movement sleep behavior disorder.
Conclusions:
Our study confirms delayed gastric emptying in drug‐naïve, early‐stage Parkinson's disease. Normal gastric emptying in idiopathic rapid‐eye‐movement sleep behavior disorder might be explained by the fact that neurodegenerative changes in structures modulating gastric motility are not severe enough to cause a functional deficit that can be detected by the ^13^C‐octanoate breath test. © 2011 Movement Disorder Society
