Self-Induced Stretch Syncope: An Unusual Non-Epileptic Paroxysmal Event. A Case Report and Literature Mini-Review.

Stretch syncope (SS) is a benign, uncommon, distinct condition described mainly in adolescent males. It is responsible for paroxysmal events started by stereotyped stretching actions with neck hyperextension, culminating in alteration of consciousness. Motor manifestations are often present and may be associated with a generalized slowing of the electroencephalographic activity, challenging the diagnosis. Despite a few cases reported in the literature, different mechanisms have been implied in the pathogenesis, involving both local and systemic hemodynamic phenomena. Here, we report on an 8-year-old girl with self-induced SS, providing new insights into the related neurophysiological profile and discussing the possible etiology. Our evidence of transient and dynamic vascular impairment supports the hypothesis of SS as a multifactorial disorder.
