What does diagnosis cost?

Frequently asked questions

Can ADHD only be diagnosed in adulthood?

Yes. The disorder begins in childhood but is often recognised later – especially in inconspicuously masked courses.

Is a self-test enough for diagnosis?

No. Self-tests are only screening tools. Diagnosis is made exclusively by qualified specialists.

How long does it take to get a result?

Depending on region and practice, between a few weeks and several months. The actual assessment often takes one to three appointments.
