If you think you may have adult ADHD, the usual first step is to talk with a primary care clinician or a mental health professional for a formal evaluation; there is no single blood test or scan that diagnoses ADHD.[1][5][6] A proper diagnosis usually looks at current symptoms, whether they started in childhood, whether they affect more than one area of life, and whether something else could better explain them.[1][5][6]
What the evaluation typically involves:
- A clinical interview about your symptoms, work/school history, relationships, sleep, mood, substance use, and daily functioning.[1][2][5]
- Screening questionnaires or rating scales such as the ASRS, DIVA, or CAARS to structure the assessment.[1][2][5]
- Checking childhood onset, often by asking about your early history or, if possible, speaking with someone who knew you as a child.[1][2][5]
- Ruling out other causes such as anxiety, depression, sleep problems, medical issues, or substance use.[1][5][6]
- In some cases, more than one visit is needed to confirm the pattern and exclude alternatives.[1]
A diagnosis in adults generally requires at least five symptoms of inattention and/or hyperactivity-impulsivity for six months or longer, symptoms in at least two settings (for example, home and work), measurable impairment, and evidence that some symptoms were present before age 12.[1][2][6]
How to get started:
- Make an appointment with your primary care provider and say you want an adult ADHD evaluation.[8]
- If needed, ask for a referral to a psychiatrist, psychologist, or other clinician experienced in adult ADHD.[1][5]
- Bring a short written list of:
- your main symptoms
- where they happen
- when they started
- how they affect work, home, and relationships
- any childhood signs you remember
- current medications, sleep issues, anxiety, depression, or substance use concerns[1][5][6]
- If you have old school reports or someone who can describe your childhood behavior, that can help the clinician.[2][5]
A useful way to think about it: self-screening questionnaires can help you decide whether to seek care, but they do not diagnose ADHD.[1][2] A formal diagnosis comes from a clinician who reviews your history and symptoms in context.[5][6]
If you want, I can also help you with a step-by-step checklist for your first appointment or a list of questions to ask the clinician.
