Research Update: Sensory Over-Responsivity as an Added Dimension in ADHD

Anecdotally many Occupational Therapists who use Ayres’ Sensory Integration to inform assessment and practice report the close links between ADHD and sensory integration challenges. This article by expert Sensory Integration researchers Shelley Lane and Stacey Reynolds offers research evidence and neuroscience in strong support of the links between differences in processing and integrating sensory input for those who meet criteria for a diagnosis of ADHD.

Abstract “Years of research have added to our understanding of Attention Deficit Hyperactivity Disorder (ADHD). None-the-less there is still much that is poorly understood. There is a need for, and ongoing interest in, developing a deeper understanding of this disorder to optimally identify risk and better inform treatment. Here, we present a compilation of findings examining ADHD both behaviorally and using neurophysiologic markers. Drawing on early work of McIntosh and co-investigators, we examined response to sensory challenge in children with ADHD, measuring HPA activity and electrodermal response (EDR) secondary to sensory stressors. In addition, we have examined the relationship between these physiologic measures, and reports of behavioral sensory over-responsivity and anxiety. Findings suggest that sensory responsivity differentiates among children with ADHD and warrants consideration. We link these findings with research conducted both prior to and after our own work and emphasize that there a growing knowledge supporting a relationship between ADHD and sensory over-responsivity, but more research is needed. Given the call from the National Institute of Health to move toward a more dimensional diagnostic process for mental health concerns, and away from the more routine categorical diagnostic process, we suggest sensory over-responsivity as a dimension in the diagnostic process for children with ADHD”.

Research Update: Occupational Therapy Interventions for Children and Youth With Challenges in Sensory Integration and Sensory Processing: A School-Based Practice Case Example

From AOTA May 2019

“Evidence Connection articles provide case examples of how practice decisions may be informed by findings of systematic reviews sponsored by the American Occupational Therapy Association Evidence-Based Practice Project. This Evidence Connection article is the second article in a two-part series. The first article described a case report of occupational therapy provided to a child with a diagnosis of autism spectrum disorder and challenges in sensory integration in a clinic setting (Parham et al., 2019). This article describes the same child’s occupational therapy service delivery by the occupational therapist working in the school setting.”

CPD Update: Neurodevelopmental Soft Signs: Implications for Sensory Processing and Praxis Assessment—Part One

An interesting read, this AOTA CE Article links sensory integration and processing difficulties and higher functions linked to occupation and participation. 
A table in the article links types of neurodevelopmental soft signs (NSS) in Occupational Therapy evaluation and underlying brain areas implicated in the literature, commenting that
“Integrating clinical observations of NSS with advanced brain-based research expands our understanding of the sensorimotor scaffolding that leads to higher functions of behavior organization, communication, and cognition.”
