No, there is a high correlation between ADHD, SPD, and PDA. In fact, most PDA children also have sensory sensitivities (e.g., light, touch, sound), and a 2020 study indicates that ADHD may be more closely correlated with, and a better predictor of, PDA than autism is. While there are not yet large-scale prevalence studies on PDA, a 2016 study suggested that around 30% of people with ADHD are also PDA.
