Frequently Asked Questions

What helps after a late ADHD diagnosis?

Multiple approaches can help. Learning about ADHD, seeking professional support through therapy or coaching, accessing accommodations, and connecting with others with ADHD are important.

However, if ADHD significantly affects daily functioning, professional support through therapy, coaching, or medication is often recommended.

Yes.
