Rotigotine is effective for depressive symptoms accompanying periodic limb movement disorder or restless legs syndrome

We report two cases who had been diagnosed with major depression, but found to have periodic limb movement disorder (PLMD) or restless legs syndrome (RLS) as major disorder. Both patients had difficulties in occupational and/or daily lives. In neither case, antidepressants were effective in symptom remission. In contrast, rotigotine transdermal patch was effective not only for core symptoms of PLMD or RLS but also for accompanying depressive symptoms. Since PLMD and RLS are associated with dopaminergic dysfunction etiologically, a dopamine receptor agonist rotigotine might be a good choice for patients with PLMD or RLS accompanying depression.
