What sensory processing disorder says about autism

Jack Craven has superpowers. When his mother, Lori, misplaces an item in the house, she asks the 12-year-old to “look in your head,” through the rich catalog of visual information he seems to assemble without effort. Jack always finds the lost object. His astonishing memory for faces enables him to pick out someone he’s seen only once or twice before from a sea of strangers in a crowded school gymnasium. His sharp hearing makes him an excellent vocal mimic. Request that he sing a Beatles tune and he’ll ask if you want it sung in the style of Lennon or McCartney.

But great powers, as any superhero narrative goes, come with great challenges. He endures, rather than enjoys, the arcade birthday parties popular among tween boys in suburban Atlanta where he lives. They’re just too noisy, too busy, too overstimulating. Jack’s hearing is so sensitive that he can’t always eat at the table with his family, because the sound and sight of them chewing might make him throw up. As an infant, he never slept for more than four hours at a stretch, and had to be held upright the whole time, his stomach pressed against his mother’s chest and her palm pressed atop his head.

Jack has sensory processing disorder (SPD), a condition that includes people who are overly sensitive to what they feel and see and hear, but also those who are undersensitive, and still others who have trouble integrating information from multiple senses at once. SPD is not an official diagnosis. It isn’t included in the newest edition of the “Diagnostic and Statistical Manual of Mental Disorders” (DSM-5). Still, it is widely used as a catch-all by clinicians, and some studies suggest that it may affect between 5 and 15 percent of school-age children. Children with the clinical label SPD also have a lot in common with children diagnosed with autism, up to 90 percent of whom also have sensory difficulties. Click here to read the rest of the story.
