Abstract
The association of psychogenic neurological features with organic neurological disease is commonly acknowledged. However, the occurrence of psychogenic dyskinesias in patients with underlying organic movement disorders is not well recognized. Six cases of psychogenic dyskinesias complicating preexisting organic movement disorders are described. This possibility must be carefully considered and excluded before an unusual movement disorder can be considered entirely psychogenic.
