Expert Opin Pharmacother. 2018 Jun 25;:1-6 Authors: Sawada H, Umemura A, Kohsaka M, Tomita S, Park K, Oeda T, Yamamoto K Abstract INTRODUCTION: Anxiety disorders are a common non-motor symptom of Parkinson's disease (PD) with a reported prevalence ranging from 20% to 50%. Although anxiety is associated with Parkinson's disease, anxiety disorders can begin before the onset of motor symptoms, and have been linked to a possible abnormality of dopaminergic, serotonergic, and adrenergic neurons that precedes motor disturbance. Area covered: Several studies have reported the pharmacological treatment of depression in PD, but none have been randomized clinical trials with a primary outcome measure of anxiety. Two trials showed that pharmacological intervention with tricyclic antidepressants or selective serotonin reuptake inhibitors proved beneficial in treating anxiety in PD. However, the effect size was modest. Anxiety is associated with off-periods and improved by L-Dopa, especially in patients with high levels of anxiety. Expert opinion: Decreasing off-periods is important for managing anxiety in patients with motor fluctuations. Minor suggestive data indicate that tricyclic antidepressants and selective serotonin reuptake inhibitors can be helpful with modest effect sizes, but the former can cause additional side effects. Only one study has examined the use of ...
