About Sensory Processing Disorder

For most people sensory integration develops in the course of ordinary childhood activities. Sensory processing difficulties can occuer across the lifespan. They can been seen in isolation or more frquently in combination with other diagnosis. These include Autistic Spectrum Disorders, Attention Deficit, Learning Disabilities, Developmental Coordination Disorder, Regulatory Disorder.

But for some people, sensory integration does not develop as efficiently as it should. This is known as sensory processing disorder [SPD] or dysfunction in sensory integration [D.S.I.]. SPD can effect academic achievement, personal identity, activities of daily living, behaviour or social participation.

Sensory Integration is the neurological process that organizes sensation from ones own body and the environment. It enables everyday life.  Sensory processing difficulties can influence self-regulation, movement, learning and interaction with others. (Allen and Smith 2011) 

It can interfere with skills that support performance, such as engagement and attention, as well as skills that enable the learning of new motor skills (Cosby, 2010, Jasmin, 2009).

Sensory Integration Dysfunction or Sensory Processing Disorder are both ways to describe the difficulty some people's nervous systems have taking in, integrating and making use of sensory information.  This changes how a person then responds to changes in their own body, the environment and how they interact with it and others around them.

Getting help is important is you suspect someone has sensory processing difficulties.  

This will usually involve a referral for specialist assessment and therapy including support.

Miller’s proposed taxonomy of SPD identifies 3 main categories:

  • Sensory Modulation Disorders – Where there is difficulty grading or  regulating response to sensory stimulus. There are 3 subtypes: Sensory over-responsive ( where the individual responds too much, for too long or to too weak an intensity), Sensory under-responsive ( responds too little or needs extremely strong stimulus to became aware of stimulus)  and finally Sensory seeking (responds with intense searching for more or stronger stimulus)
  • Sensory Based Motor Disorder – Divided into 2 proposed subtypes: Postural disorder, with disordered balance and core stability and Dyspraxia which encompasses sequencing, motor planning and organization
  • Sensory Discrimination Disorder – difficulty interpreting the specific characteristics of  sensory stimuli (e.g intensity, duration, speed and timing). Can be present in  any of the 7 senses (Touch, proprioception, vestibular, visual, auditory, olfactory or gustatory)
