Many child psychiatrists do not see SPD as a distinct diagnostic label. They say the symptoms are too diverse and there’s too much uncertainty about what SPD is and how to distinguish it from other conditions such as autism, attention deficit hyperactivity disorder (ADHD) or anxiety. “We know that sensory issues are important in a variety of kids with a variety of different diagnostic labels,” says Carissa Cascio, assistant professor of psychiatry at Vanderbilt University in Nashville, Tennessee. Those who have sensory problems without any of the other conditions are rare, she says.
But some parents say this doesn’t jibe with their experience, and that their children’s problems are fundamentally perceptual in nature.
