About one-third of stroke survivors develop this physical sign []. The startle reflex is a response modulated by affective states: it has been reliably used in the literature to measure the aversiveness of emotive stimuli. In majority of the cases, the cause of exaggerated startle response is hereditary, because this disorder is considered as autosomal dominant trait. This simple reflex is triggered by pressing a finger or other object into the palm of a newborn’s hand. Department of Health and Human Services, is the nation’s medical research agency — making important discoveries that improve health and save lives. Certain actions or sensations produce specific muscle reactions. Hypervigilance is one of the central features of post-traumatic stress disorder (PTSD). And they can actually grip pretty hard. The origin of the startle reflex lies in the caudal brainstem; it can be elicited by an unexpected stimulus resulting in a bilateral activation of many muscles. In contrast, the startle reflex recruits muscles around the eyes and in the cheeks. Given to any baby with respiratory distress. Hyperekplexia is a rare hereditary, neurological disorder that may affect infants as newborns (neonatal) or prior to birth (in utero). 3.

Post-traumatic stress disorder (PTSD) patients are considered to have excessive EMG responses in the orbicularis oculi (OO) muscle and excessive autonomic responses to startling stimuli. Sometimes this state of readiness can show up as the startle response. The startle reflex is considered a primitive physiological reflex, a defense response that occurs in the organism when the body feels sudden danger and uneasiness, characterized by habituation and sensitization effects, and studies on the startle reflex often deal with pre-pulse inhibition (PPI) and sensorimotor gating.

Acoustic startle reflex (ASR) constitutes a reliable, cross-species indicator of sensorimotor and inhibitory mechanisms, showing distinct signature in cognitive aging, sex, and psychopathological characterization. Startle syndromes are paroxysmal and show stimulus sensitivity, placing them in the differential diagnosis of epileptic seizures. The startle response to unexpected auditory and somaesthetic stimulation was studied in 8 patients with hereditary or symptomatic hyperekplexia. The midbrain functions as a relay system, transmitting information necessary for vision and hearing. Taken together, our results show that hASR is a cortically-mediated behaviour, and suggest that it could be a new clinical item to clearly and accurately identify non-communicating patients who are in the minimally conscious state.
