PAROXYSMAL DYSKINESIA
A review concerning a rare type of hyperkinesia - paroxysmal dyskinesia (PD) - is presented. The evolution of views on the etiology, pathogenesis of PD, variants and classification criteria, and genetic factors associated with PD are demonstrated. The variants of clinical forms of PD are also investigated: kinesigenic, non-kinesigenic, exercise-induced, hypnogenic, and benign paroxysmal torticollis of infancy. The main causes of secondary PD are highlighted. Modern approaches to the issues of diagnosis, differential diagnosis and treatment of various PD variants are described.
