Major discovery for basis of Sensory Processing Disorder in children


1. Sensory Processing Disorders (SPD)  are as common as ADHD.

2. SPDs are more prevanlent in children than autism.

3. SPD hasn't been recognized as a distinct disease.

4. SPDs affect 5-16% of kids.

5. Kids with SPD can have hypersensitivity to sound, sight, touch (think fabric or food textures). They can also have poor fine motor skills and be easily distracted.

But a new study found that kids with SPD have differences in their brain structure. The researchers used DTI (diffusion tensor imaging) and found that kids with SPD had abnormal white matter tracts - mostly in areas in the back of the brain (which connect auditory, visual and tacticle systems).

In ADHD and ASD (autism spectrum disorders), there are more frontal anterior white matter tracks.

It appears that the abnormal white matter tracks alters the timing of sensory transmission, making it hard or impossible to process sensory stimuli and integrate information across multiple senses.

Here's the summary of the research:
