Sensory Processing Disorder affects one in twenty children. Standardized assessments identify the condition with accuracy rates from 65 to 92 percent across multiple tools. The same data link untreated SPD to triple the risk of anxiety disorders and other lasting comorbidities.
Key Takeaways
- The Sensory Profile assessment identifies SPD in 92% accuracy for sensory modulation disorders
- Children with untreated SPD have 3x higher risk of anxiety disorders in adolescence
- Sensory Processing Disorder (SPD) affects between 5% and 16% of school-aged children according to epidemiological studies
- Children with SPD often display tactile hypersensitivity, with 60-70% avoiding certain clothing textures
- Sensory Integration therapy improves SPD symptoms in 70% of children after 6 months
About 1 in 20 children have sensory processing disorder, affecting how they respond to everyday stimuli.
