Psychogenic palatal tremor

Mov Disord. 2006 Feb;21(2):274-6. doi: 10.1002/mds.20731.

Abstract

We describe a case of psychogenic palatal tremor. The diagnosis was supported by clinical criteria and neurophysiological testing, including frequency analysis and jerk-locked back-averaging. We discuss the differential diagnosis of palatal tremor as well as the role of neurophysiological testing in the diagnosis of psychogenic movement disorders.
