INFLUENCE OF PHOTOSENSITIVITY ON THE DEVELOPMENT OF JUVENILE MYOCLONIC EPILEPTIC SEIZURES

Abstract

Introduction: Epilepsy is a neurological disorder triggered by hyperarousal, causing seizures, and may have known or unknown genetic factors. Among the forms of reflex epilepsies we have the juvenile myoclonic, which affects the young population with myoclonic and tonic-clonic seizures, being generated by the photosensitivity of these patients. Objective: to establish the relationship between photosensitivity as a causative factor of juvenile myoclonic epilepsy, under the justification that this pathology markedly affects the lives of patients with this syndrome. Methodology: This is a systematic bibliographic review, of a descriptive nature and a quantitative approach. Results: from the application of the methodology, 17 scientific productions were found, of which a table was read in full and elaborated. Discussion: Photosensitivity is closely related to the development of juvenile myoclonic epilepsy, due to photoparoxysmal responses, behaving as a triggering factor, in addition to the intimate relationship of Juvenile Myoclonic Epilepsy (JME) with the sleep-wake cycle, awakening and several genes that contribute to its emergence and consequently reduction in the quality of life of carriers. Final considerations: It is notorious that for the onset of JME, the altered functional connectivity of excitation networks may contribute to the understanding of myoclonus after awakening, while increased connectivity of the posterior thalamus may explain photosensitivity.
