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.
Results
Subjects with dysautonomia had greater odds of clinically meaningful change in motor features (odds ratio [OR]: 3.0), cognition (OR: 3.4), and anxiety (OR: 4.3) compared to those without dysautonomia.
