Models of hyperkinetic disorders in primates.

Hyperkinetic movement disorders include tremors, dystonia, chorea, tics, myoclonus, stereotypies, restless legs syndrome, and various other disorders with abnormal involuntary movements. Although several disorders could be included in such a broad spectrum, a limited number of conditions are modeled in non-human primates. These disabling conditions include notably L-dopa-induced dyskinesia in Parkinson's disease, tardive dyskinesia, essential tremor and Huntington's disease. Non-human primate models of these conditions exist. This short opiniated review surveys the current state of use of these models as well as the future developments.
