Sporadic Hyperekplexia Plus Syndrome
A disorder of infants and children with pathological startle response, features of other system involvement, falls, and stiffness with retained consciousness. It should be differentiated from conditions such as myoclonic epilepsy, psychogenic movement disorder, Isaac syndrome, Schwartz-Jampel syndrome, Gilles de la Tourette, and culture-specific startle syndromes such as jumping Frenchman of Ma...
متن کاملSporadic hyperekplexia due to self-limiting brainstem encephalopathy
Hyperekplexia is a rare movement disorder characterized by pathologically exaggerated response to unexpected stimuli. It is differentiated from the normal startle reflex by its lower threshold, higher intensity, and resistance to habituation. Many of the acquired hyperekplexias result from brainstem involvement such as encephalitis, infarct, hemorrhage, pontocerebellar hypoplasia and medullary ...
متن کاملNeonatal hyperekplexia: the Stiff-Baby syndrome.
Neonatal hyperekplexia is a rare autosomal dominant startle disorder. Presenting soon after birth, it is often mistakenly diagnosed as spastic quadriparesis, epilepsy etc. While the long-term prognosis is relatively benign, sudden death due to severe spasms have been seen in sporadic cases. We report a case of hyperekplexia with some typical and some unusual findings.
متن کاملLate onset hyperekplexia.
We report on the case of an 86-year-old woman who rapidly became unable to stand and walk because of jerky movements, suggesting a clinical diagnosis of myoclonus. It was observed that both unexpected and expected stimuli (audiogenic, tactile, or visual) triggered the myoclonic jerks. Electrophysiological exploration, including a coupled EEG-EMG study, showed the occurrence of a patterned motor...
متن کاملHyperekplexia in neonates.
Hyperekplexia (startle disease) is a rare non-epileptic disorder characterised by an exaggerated persistent startle reaction to unexpected auditory, somatosensory and visual stimuli, generalised muscular rigidity, and nocturnal myoclonus. The genetic basis is a mutation usually of the arginine residue 271 leading to neuronal hyperexcitability by impairing glycinergic inhibition. Hyperekplexia i...
