Frequently Asked Questions (FAQs)
What does an ADHD evaluation involve?
An ADHD evaluation with our team involves a comprehensive assessment of attention, hyperactivity, and impulsivity through clinical interviews, standardized rating scales completed by parents, teachers, and the individual (when appropriate), as well as behavioral observations. We integrate all of this information to determine whether the diagnostic criteria for ADHD are met.
Why is a professional ADHD diagnosis important?
A formal diagnosis allows access to appropriate educational accommodations, therapeutic interventions (like behavioral therapy and executive function training), and, if necessary, medication management. It also provides a framework for understanding and addressing the individual’s specific challenges.

Can an ADHD diagnosis help with school?
