Self-Assessment Questions


Answer 7
  1. Palatal tremor. Palatal tremor is characterized by rhythmic involuntary jerky movements of the soft palate of the throat and can be classified as ordinary (caused by a lesion in the triangle of Guillain Mollaret) or essential (with no identifiable lesion). Palatal tremor is one of the few movement disorders that persists during sleep. Improvement of palatal tremor is reported after administration of flunarizine and injection of botulinum toxin A into the tensor muscles of veli palatini.
