Medical term:
Hyperexplexia
hy·per·ek·plex·i·a
(hī'pĕr-ek-plek'sē-ă), [MIM*149400]A hereditary disorder in which there are pathologic startle responses, that is, protective reactions to unanticipated, potentially threatening, stimuli of any type, particularly auditory; the stimuli induce often widespread and violent sudden contractions of the head, neck, spinal, and sometimes, limb musculature, resulting in involuntary shouting, jerking, jumping, and falling; autosomal dominant and recessive inheritance forms, with the responsible gene localized to chromosome 5q; probably the result of lack of inhibitory neurotransmitters, glycine, or GABA.
Synonym(s): kok disease, startle disease
[hyper- + G. ekplēxia, sudden shock, fr. ekplēssō, to startle]
