Sensory processing disorder: Key points of a frequent alteration in neurodevelopmental disorders

Abstract Altered neurological sensory integration results in Sensory Processing Disorder (SPD), also known as Sensory Regulation Dysfunction, Sensory Integration Dysfunction or Sensory Dysfunction Disorder. Under this condition, the brain doesn’t process sensory inputs correctly, following inappropriate behavioral and motor responses that affect learning, coordination, behavior and language. SPD may lead to stress, anxiety or even depression, and represents a risk of psychopathology. Epidemiological studies carried out in western lifestyle populations have shown a high prevalence of SPD among children (5-15%); however, a large number of health professionals still do not know this condition, giving rise to unattended children and frustrated families. This review aims to provide an updated starting point about some of the most relevant aspects of SPD.
