title: Late-onset akathisia--an indicant of covert dyskinesia: two case reports.
abstract: Two patients receiving long-term depot antipsychotic treatment developed late-onset akathisia characterized by emergence toward the end of each injection interval. Drug dose reduction provoked exacerbation of the akathisia and the appearance of choreiform limb dyskinesia. The authors discuss a possible pathophysiological mechanism.
