Enteric synucleinopathy: real entity or only a trendy concept?
An accumulating body of literature has emerged in the past 25 years to show that Parkinson’s disease (PD) is not only a disorder of the brain but also of the gastrointestinal tract and more generally of the gut-brain axis. Gastrointestinal symptoms occur in almost every PD patient at some point and...
