Psychogenic palatal tremor.
Recent criteria for the classification of palatal tremor use clinical, imaging, and electrophysiological features to differentiate essential and symptomatic forms. A case of probable psychogenic palatal tremor (PPT) is described within the context of these criteria, which lack clear guidelines for diagnosing PPT. The heterogenous nature of essential palatal tremor and its relationship with PPT, voluntary palatal movements, and tics is discussed.
