Migraine and restless legs syndrome: current perspectives

The relationship between migraine and restless legs syndrome (RLS) has been described in the literature for some years, based on clinical findings and pathophysiological considerations. There are some possible factors relating migraine and RLS. Both are diseases involving the central nervous system, the two diseases seem to share a dopaminergic mechanism, and it is also believed that they may share a genetic origin. At present, doctors who work with these two diseases should be encouraged not to simply investigate the simultaneous presence of both, but should also apply a treatment better adapted to this possibility. Research should be directed at some still unanswered questions for a better understanding of the association between migraine and RLS.
