Abstract:

Introduction . Although antidepressants are widely used in Parkinson's disease ( PD ) , few well - designed studies to support their efficacy have been conducted . Development . These clinical guidelines are based on a review of the literature and the results of an AMN movement disorder study group survey . Conclusions . Evidence suggests that nortriptyline , venlafaxine , paroxetine , and citalopram may be useful in treating depression in PD , although studies on paroxetine and citalopram yield conflicting results . In clinical practice , however , selective serotonin reuptake inhibitors are usually considered the treatment of choice . Duloxetine may be an alternative to venlafaxine , although the evidence for this is less , and venlafaxine plus mirtazapine may be useful in drug - resistant cases . Furthermore , citalopram may be indicated for the treatment of anxiety , atomoxetine for hypersomnia , trazodone and mirtazapine for insomnia and psychosis , and bupropion for apathy . In general , antidepressants are well tolerated in PD . However , clinicians should consider the anticholinergic effect of tricyclic antidepressants , the impact of serotonin - norepinephrine reuptake inhibitors on blood pressure , the extrapyramidal effects of antidepressants , and any potential interactions between monoamine oxidase B inhibitors and other antidepressants .
