In 2023, an estimated 15.5 million U.S. adults had an ADHD diagnosis, approximately one half of whom received their diagnosis in adulthood. Approximately one third of adults with ADHD take stimulant medication; 71.5% had difficulty filling their prescription because the medication was unavailable.

I’ve linked to the primary source, the journal article, in the post above. In this comment, for those interested, here’s the abstract:

Summary

What is already known about this topic?

Attention-deficit/hyperactivity disorder (ADHD) is a common childhood disorder that can continue into adulthood, but there is limited information about diagnosis and treatment in adults.

What is added by this report?

In 2023, an estimated 15.5 million U.S. adults had an ADHD diagnosis, approximately one half of whom received their diagnosis in adulthood. Approximately one third of adults with ADHD take stimulant medication; 71.5% had difficulty filling their prescription because the medication was unavailable. Approximately one half of adults with ADHD have ever used telehealth for ADHD services.

What are the implications for public health practice?

ADHD affects many adults. Information on diagnosis and treatment helps the development of clinical care guidelines and regulatory decision-making around medication shortages and telehealth for ADHD.
