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 ...

ized by onset in the late second or early third decade of life with a progressive, disabling, and drug-resistant action myoclonus and an invariably fatal course. The diagnosis is challenging until the full clinical picture is present. Progressive myoclonus ataxia or epilepsy with SCARB2 mutations should be distinguished from Unverricht-Lundborg disease, myoclonic epilepsy with ragged-red fibers...

The previously unrecognised association of myoclonus in two patients with LHON with the 11778/ND4 pathogenic mutation is described. EEG failed to disclose epileptic figures, and a back averaging study suggested that myoclonus was cortical in origin in both patients.

BACKGROUND The various medical treatments applied to myoclonus-dystonia patients with a mutation of the ε-sarcoglycan gene (SGCE) have not been beneficial in most cases. Most patients experience progressive deterioration or static clinical courses, with only rare cases of spontaneous remission. CASE REPORT A 19-year-old girl presented with a 14-year history of myoclonus and dystonia that seve...

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...

BACKGROUND Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disorder that is characterized by involuntary eye movements and myoclonus. OMS exhibits various etiologies, including paraneoplastic, parainfectious, toxic-metabolic, and idiopathic causes. The exact immunopathogenesis and pathophysiology of OMS are uncertain. CASE REPORT We report the case of a 19-year-old male who develop...

Epileptic negative myoclonus is an uncommon seizure type characterized by a sudden, brief loss of muscle tone that may lead to falling. It has been associated largely with benign childhood epilepsy with centrotemporal spikes (rolandic epilepsy), although it may also be a feature of other epileptic syndromes. In patients with rolandic epilepsy, epileptic negative myoclonus usually appears during...
