Restless leg syndrome (RLS) is a common disorder, frequently of unclear origin, which is often associated with significant distress. There are a few case reports of atypical antipsychotic agents (AAP) causing RLS. The pathophysiological mechanisms resulting in emergence of these movements suggest central dopaminergic dysfunction. Dopamine agonists and L-dopa reduce the symptoms of RLS, and some agents that block the dopaminergic system aggravate RLS. Genetic influences are implicated in RLS and an association between gene polymorphisms and antipyschotic-associated onset of RLS has been postulated. Greater awareness of potential causes of RLS, and its differentiation from akathisia and illness-related agitation might help in reducing the distress associated with it and improving patient compliance in patients using atypical antipsychotic agents.
