Four patients with palatal myoclonus were examined electromyographically. Surface EMG was recorded simultaneously from several myoclonic muscles and the correlation between their rhythmic discharges was shown. The possible existence of a remote influence of palatal myoclonus was tested by recording soleus and anterior tibial H-reflexes and seeking a correlation of their amplitudes with the rhyt...

The cause of objective tinnitus provoked by palatal and middle-ear myoclonus may be identified by magnetic resonance imaging of the central nervous system in the Guilliain-Mollaret triangle or it may be idiopathic. The idiopathic cases are rare. From the literature, one can perceive the following unanswered questions: (1) Are palatal and middle-ear myoclonus different entities or do they usuall...

INTRODUCTION Various presentations of essential palatal myoclonus, a condition characterized by clicking noises and palatal muscle spasm, have been reported in the literature. We are reporting the first case of essential palatal myoclonus following dental treatment. CASE PRESENTATION A 31-year-old Caucasian man presented to our Ear, Nose and Throat department complaining of objective clicking...

Essential palatal myoclonus is a rare movement disorder consisting of continuous rhythmic jerks of the soft palate; it usually develops secondary to brainstem or cerebellar disease called symptomatic rhythmic palatal myoclonus. Diagnosis is usually clinical, and some patients, however, fail to show evidence of a structural lesion like our patient called essential rhythmic palatal myoclonus. We ...

Palatal myoclonus is usually due to a brainstem or cerebellar lesion disrupting the dentato-rubro-olivary pathway. Rarely it may be caused by a cortical lesion. The precipitating factor in 70% of all cases is an infarct. We describe an unusual case of a patient with palatal myoclonus who had an old ipsilateral cerebellar infarct and a new contralateral subcortical (corona radiata) infarct. We p...

objective: hashimoto encephalopathy (he) is known as a steroid-responsive encephalopathy associated with autoimmune thyroiditis or nonvascular inflammation-related autoimmune meningoencephalitis. the average age of onset of he is approximately 50 years; and it is more common in women. the onset of he may be acute or subacute. the course of most he cases is relapsing and remitting, which is simi...

OBJECTIVES/HYPOTHESIS To review the clinical characteristics and management of patients with palatal myoclonus and devise an algorithm for treatment with botulinum toxin based on presenting symptoms, clinical examination findings, and involved muscle groups. STUDY DESIGN Retrospective chart review at two clinical research centers. METHODS Between 1985 and 2011, 15 patients with a diagnosis ...
