Abstract

Altered neurological sensory integration results in Sensory Processing Disorder (SPD), also known as Sensory Regulation Dysfunction, Sensory Integration Dysfunction or Sensory Dysfunction Disorder....

Highlights

  • IntroductionSensory receptors capture external stimuli from the environment (through tactile, visual, gustatory, olfactory or auditory receptors) or internal stimuli originated in our own body (via tactile, vestibular or proprioceptive receptors)

  • Sensory receptors capture external stimuli from the environment or internal stimuli originated in our own body

  • This study showed that the Sensory Processing Disorder (SPD) group would have an intermediate phenotype between Autism Spectrum Disorder (ASD) and normotypic development with regard to somatosensory processing that may be detected by MEG-based techniques

Summary

Introduction

Sensory receptors capture external stimuli from the environment (through tactile, visual, gustatory, olfactory or auditory receptors) or internal stimuli originated in our own body (via tactile, vestibular or proprioceptive receptors). These receptors transform the captured stimulus into sensory information that is sent to the brain to be processed, resulting in a determined motor and behavioral response. Some authors divide the SI process in 4 phases (Del Moral Orro et al, 2013): registration (the brain receives sensory information from sense organs); modulation (allows the regulation of stimulus intensity); discrimination (the stimulus is organized and interpreted to distinguish its relevance, characteristics and specific qualities) and response (the brain integrates all the processed stimuli to generate an appropriate response that will lead to a particular behavior and movements). The present work aims to provide a general and updated starting point about this disorder, reviewing several important aspects such as assessment, prevalence, related factors and comorbidity, related problems, common signs, candidate biomarkers and treatment
