Sensory stuff is, to my mind, a symptom/comorbid not a cause. Remediation via OT and careful activity choices helpe my DD a lot. Not enough, so THEN we admitted the likely ADHD/ASD and wet seeking help, but it's hard enough to diagnose a gifted, high functioning / borderline kid without having done the therapy they will recommend BEFORE attempting diagnosis. So my advice to myself 3 years ago would have been - don't put the cart before the horse.
