Yoshikazu Ugawa, MD, Fukushima Medical University, Fukushima, Japan, describes the difficulties with defining and treating dyskinesia. There is no universal definition of dyskinesia and it features in a range of movement disorders. Dyskinesia can be present from an overdose in Parkinson’s medication or antipsychotics. The first mode of treatment is to change medication. However, for patients on antipsychotics this can be challenging as psychiatric symptoms can worsen. For patients with movement disorders, as a last resort deep brain stimulation (DBS) may be used. This interview was recorded during an online conference call with The Video Journal of Neurology (VJNeurology).
