names

Terms for more specific subtypes:

• "sensory modulation disorder" (referring to hypo-sensitivity or hyper-sensitivity)
• "tactile defensiveness" and "auditory defensiveness"

recognition by professional organizations

• DSM-5 During the version 5 revision process, it was considered for inclusion in Section 3 "Disorders needing further research", but was rejected from that too.
• ICD-10

It is recognized by:

• CPT (updated yearly)
  97533. Sensory integrative techniques to enhance sensory processing and promote adaptive responses to environmental demands, direct (one-on-one) patient contact by the provider, each 15 minutes
• DC: 0-3R (published 2005)
  400. Regulation Disorders of Sensory Processing
  410. Hypersensitive
  
  411. Type A: Fearful/Cautious
  412. Type B: Negative Defiant
  
  420. Hyposensitive/Underresponsive
  430. Sensory Seeking/Impulsive
  ...
  The Revision Task Force concluded that at this stage of our knowledge, DC:0–3R could neither provide detailed criteria for subtypes of Regulation Disorders of Sensory Processing nor specify the number of criteria needed for diagnosis. Instead, we provided criteria in rich descriptive form in the hope that future research will clarify this area.

review articles

• 2012 policy statement by the American Academy of Pediatrics
  "it is unclear whether children who present with sensory-based problems have an actual 'disorder' of the sensory pathways of the brain or whether these deficits are characteristics associated with other developmental and behavioral disorders. Because there is no universally accepted framework for diagnosis, sensory processing disorder generally should not be diagnosed. Other developmental and behavioral disorders must always be considered, and a thorough evaluation should be completed. Difficulty tolerating or processing sensory information is a characteristic that may be seen in many developmental behavioral disorders, including autism spectrum disorders, attention-deficit/hyperactivity disorder, developmental coordination disorders, and childhood anxiety disorders.

  "Occupational therapy with the use of sensory-based therapies may be acceptable as one of the components of a comprehensive treatment plan. However, parents should be informed that the amount of research regarding the effectiveness of sensory integration therapy is limited and inconclusive."

• hypokalemic sensory overstimulation Further information specific to my personal exploration of this:
  • elsewhere: "Spironolactone can also sometimes be used to replace potassium supplements [but it varies by patient, so you need a blood test to confirm this]" (read further: signs and symptoms of hyperkalemia)
  • "Potassium should be taken with ample volumes of water"
