Defining the Problem

Finally, a word on recognizing, testing, and treating sensory integration problems. The concept behind these problems has been around since the late 1970s, when occupational therapist A. Jane Ayres presented a theory unifying some children's highly exaggerated sensory responses—of touch, taste, sight, smell, and sound—under the term Sensory Integration Dysfunction (SID).

For example:

• A child with auditory defensiveness may cover his ears and throw a tantrum if his kindergarten class sings a song together.
  
  
• A child with tactile defensiveness may violently resist wearing shoes or may be agitated by the inside tags in her clothing.

Perhaps because SID has been largely studied and treated by occupational therapists rather than psychologists, and because its definitions are still being clarified, SID does not appear in the DSM-IV, the official manual of mental disorders. Diagnosis and treatment of SID, then, must usually be undertaken by an occupational therapist certified to administer the Sensory Integration and Praxis Tests (SIPT).

While not categorized as an Autism Spectrum Disorder, SID presents parents with the similar challenge of early detection and intervention—not because SID can be cured, but so that the child and his family know how best to minimize and adjust to the symptoms.
