Association between nocturia and anxiety in Parkinson's disease.

Objective: The objective of the study was to determine whether there exists any relationship between nocturia and anxiety in patients with Parkinson's disease (PD). Although the exact cause of anxiety and nocturia in PD is unknown, we hypothesized that there is a relationship between these two PD symptoms. Anxiety may exacerbate nocturia or an opposite relationship may be present in which nocturia may result in heightened levels of anxiety.

Prevalence of nocturia in Parkinson's disease patients from various ethnicities.

Objectives: One of the most common non-motor symptoms in Parkinson's disease (PD) is nocturia. This paper seeks to address the prevalence of nocturia in PD and correlate it to various factors such as gender, Hoehn and Yahr (H&Y) stage, age, and ethnicities.

Methods: In particular, 332 PD patients were seen in a community movement disorders clinic and their charts were analyzed from 2005 to 2010.
