What a 20-Minute ADHD Evaluation Can and Can't Tell You

Direct-to-consumer ADHD platforms removed real barriers, and many adults got correct diagnoses through them.

A DSM-5-TR ADHD diagnosis requires childhood history, impairment in two settings, and ruling out mimics.

Evaluation depth matters far more than whether the visit happens by video or in an office.

Direct-to-consumer attention-deficit/hyperactivity disorder (ADHD) telehealth platforms typically deliver a 20-to-30-minute video visit supported by a self-report rating scale. Wait times for a traditional psychiatric evaluation in much of the country run months. Those two facts explain almost everything about why these platforms grew so fast, and both belong in any honest discussion of them.

I want to start with what the platforms got right, because the criticism is usually one-sided. They solved an access problem that was real and, in parts of the country, severe. They removed geography, scheduling friction, and a great deal of stigma. A large number of adults, particularly women whose ADHD had been missed for decades, received a correct diagnosis and effective treatment they wouldn't otherwise have pursued. That's a genuine public health contribution, and I treat patients by telehealth myself across four states, so none of what follows is an argument against the screen.

The limitation lives in evaluation depth. A video connection can carry a full evaluation. A 20-minute slot cannot.
