Studies suggest between 5 and 13 percent of preschool children are affected by SPD. However, SPD is not recognized as a disorder in standard medical manuals like the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), in which more well-known disorders like depression and schizophrenia exist. Some experts believe SPD isn’t a separate condition, but a symptom of other ailments like autism or ADHD.
Sophie Molholm, an associate professor of pediatrics and neuroscience at Albert Einstein College of Medicine in New York, has been working on new research with a group of pure-SPD types (those who don’t have any other conditions like autism), to measure their brain activity and see if there are any major differences in sensory input and how they put together sensory input. Her preliminary evidence suggests children with SPD have a larger brain response to sensory stimulation than an age-match control group.
“But we can’t say why at this point,” Molholm told FoxNews.com. “It’s very tempting to say something like, ‘This is either the brain amplifying the response or failing to dampen the response,’ but that would be purely speculative. We still have a lot more work to do.”
