![]() 17 reported that strong reactions to typical sensations were correlated with ritualism in a community based sample of young children. Sensory over-responsivity and OCD symptoms are moderately correlated in non-clinical populations as well 17, 18. Rieke and Anderson 15 confirmed that adults diagnosed with OCD scored higher than the Adolescent/Adult Sensory Profile published norms 16 on sensory sensitivity and sensory avoidance. Sensory over-responsivity was nearly twice as prevalent among children (i.e., preschoolers) than adolescents. SOR was relatively common, with 32.5% of participants experiencing tactile sensitivity, 20.3% visual or auditory sensitivity, and 20.5% gustatory/olfactory sensitivity. ![]() 12 extended Hazen’s work by examining sensory over-responsivity in a sample of children ages 3–17 years diagnosed with OCD. Sensory-avoidance behaviors were the primary presenting symptoms in the absence of obsessive thoughts, suggesting that atypicalities in sensory processing and integration occur in at least a subset of OCD patients. 14 examined a series of case studies to investigate how intolerance of ordinary sensory stimuli might drive compulsive behaviors in children diagnosed with OCD and/or Tourette’s Syndrome (a related disorder with repetitive behaviors). The small number of studies examining the relationship between sensory over-responsivity and OCD symptoms find that, across the lifespan, sensory sensitivities co-occur with OCD symptoms. ![]() Together these findings suggest that atypical sensory experiences may play an important role in understanding OCD. In addition, body-focused repetitive behaviors are related to a heightened awareness of somatic sensations 13. Among adults, sensory phenomena are associated with tic disorders, earlier age of onset, and poor treatment response 12. Children and adolescents are more likely than adults to report miscellaneous compulsions 11, which may include responses to sensory phenomena 10. uncomfortable feelings regarding physical sensations) drive their compulsive rituals 10. As many as 30%−70% of OCD patients report that sensory phenomena (e.g. However, not all compulsions can be attributed to obsessions. The archetypal depiction of OCD characterizes obsessions as the anxiety-provoking symptom and compulsions as the regulation of these obsessive symptoms. Having one or more OCD symptoms is associated with functional impairment and an increased risk for other behavior problems 8, 9. Among pediatric populations, 13–15% report at least one or more OCD symptoms 8, 9. However, many more individuals experience subclinical obsessive-compulsive symptoms in the absence of a formal diagnosis. Lifetime prevalence for juvenile-onset (usually 9–12 years) is relatively low (1–2.5%) 7. Obsessive-Compulsive Disorder (OCD) is an anxiety disorder characterized by persistent and ritualistic behaviors that are performed in response to intrusive thoughts, images, or ideas. Conversely, children identified as at-risk for SOR have more behavior problems than children not at-risk 3, 6. Nevertheless, children with behavior problems, particularly anxiety disorders 4 and autism spectrum disorder 5, frequently report elevated levels of sensory over-responsivity. ![]() Although not currently recognized as such, some evidence suggests that SOR symptoms comprise a distinct disorder with prevalence rates ranging from 5–20% 2, 3. SOR typically manifests as exaggerated or prolonged negative behavioral responses to ordinary sensory stimuli 1. Sensory Processing Disorder (SPD) is characterized by an inability to integrate sensory information and respond appropriately.
