Combined rasagiline and antidepressant use in Parkinson disease in the ADAGIO study: effects on nonmotor symptoms and tolerability.
Depression, cognitive impairment, and other nonmotor symptoms (NMSs) are common early in Parkinson disease (PD) and may be in part due to disease-related dopamine deficiency. Many patients with PD are treated with antidepressants for NMSs, and the effect of the combination of PD medications that enhance dopamine neurotransmission and antidepressants on NMSs has not been studied. We report the effects of the addition of a monoamine oxidase B inhibitor, rasagiline, to antidepressant treatment in PD. ⋯ The combination of rasagiline and antidepressants in patients with de novo PD is associated with reduced worsening of a range of NMSs in preliminary analyses. Adverse effects appear uncommon with this combination. These findings suggest a role for dopamine-enhancing therapies in NMSs in early PD and encourage further study and confirmation.
