Palatal Tremor / Myoclonus
Palatal tremor is a rare movement disorder that has received much attention, given its curious nature. Initially, it was more commonly referred to as "palatal myoclonus", but later renamed "palatal tremor" at the First International Movement Disorders Congress in 1990 to recognize the continuous and rhythmic nature of soft palate disturbances. Schenck (1965), recognized two types subsequently called essential palatal tremor (EPT) and symptomatic palatal tremor (SPT) by Deuschl. SPT is associated with injury to the Guillain Mollaret triangle, with transinaptic neuronal degeneration and radiological expression of inferior olivary pseudohypertrophy. EPT has no radiological correspondence and is often an isolated finding, unlike SPT, which usually has associated dysarthria, dysphonia and dysphagia. The video patient had a severe ischemic stroke and developed palatal tremor after a few months.
