The Effect of Dysautonomia on Motor, Behavioral, and Cognitive Fluctuations in Parkinson's Disease.

ABSTRACT:

Background

Motor and nonmotor fluctuations adversely impact the quality of life in Parkinson's disease (PD). Dysautonomia, a feature frequently associated with PD and a possible adverse effect of dopaminergic therapy, may be comorbid with fluctuations.

Objective

We sought to evaluate the effect of dysautonomia on motor and nonmotor fluctuations in PD.

Methods

Two hundred subjects with PD were evaluated in both on and off dopamine states to assess changes in symptoms related to dopaminergic fluctuations. Multivariable logistic regression was performed to assess the association of dysautonomia with motor, cognitive, and psychiatric worsening from on to off states with adjustment for disease duration, levodopa equivalent daily dosage (LEDD), and dopamine-agonist LEDD.
