Sensory Processing Disorder (SPD) Resource Center

Welcome To The
Sensory Processing Disorder (SPD)Resource Center

Good news… Your frustration and confusion about your child – who may have Sensory Processing Disorder (SPD) – is almost over!

Finally!… A thorough explanation and a name for the behaviors and developmental concerns that exist – which seemed almost impossible to understand or cope with.

When parents first find out about SPD, their reaction usually comes as: a “flash”, a “light bulb moment”, the “Aha!”, “So that explains it!”, “Oh, so now I understand!”, “Why didn’t someone tell me about this years ago?”

Sensory Processing Disorder: A New Name

This is the newest term for, and is synonymous with the terms, Sensory Integration Disorder, Sensory Integration Dysfunction (SI Dysfunction) and Dysfunction in Sensory Integration (DSI).

Sensory Processing Disorder is clearly classified under 3 different types… Sensory Modulation Disorder (SMD), Sensory Based Motor Disorder (SBMD), and Sensory Discrimination Disorder (SDD)

2 out of the 3 of these additionally have subtypes underneath them that more clearly define the exact nature of the disorder.

The Subtypes Under Sensory Modulation Disorder (SMD) are:

• Sensory Over-responsivity
• Sensory Under-responsivity
• Sensory Seeking

The Subtypes Under Sensory Discrimination Disorder (SDD) are:

• Postural Disorder
• Dyspraxia

At this point, the term sensory integration is still being used to describe the theory and treatment, based on the original work of A. Jean Ayres.

Sensory Processing Disorder (SPD) is used to define and describe the disorder / dysfunction symptoms – in hopes of making this a universally accepted “medical diagnosis” – thus enabling insurance reimbursement for evaluation and treatment.
