To get diagnosed with ADHD as an adult, start by speaking with your primary care physician (GP) or a mental health provider (such as a psychologist or psychiatrist) to discuss your symptoms and request a referral for a formal evaluation [1][7][10]. There is no single blood test or brain scan for ADHD; instead, a diagnosis is confirmed through a comprehensive clinical evaluation that includes a physical exam, detailed interviews about your childhood and current symptoms, and the use of ADHD rating scales or psychological tests to rule out other conditions [1][5][11].
Step-by-Step Guide to Getting Diagnosed
| Step | Action | Details |
|---|---|---|
| 1 | Self-Research & Screening | Before your appointment, complete free online screening tools like the ASRS (Adult ADHD Self-Report Scale) and WFIRS (Weiss Functional Impairment Rating Scale) to document your symptoms [2]. |
| 2 | Consult Your Doctor | Visit your GP or primary care doctor. Bring your screening results, a list of symptoms (e.g., trouble focusing, forgetfulness, restlessness), and notes on how they affect your work, home, or relationships [2][5][10]. |
| 3 | Get a Referral | Your doctor may diagnose you directly or refer you to a specialist (psychologist for testing/therapy, or psychiatrist for medication management) [2][7]. If your GP won’t refer you, you can research clinicians, check their wait times, and ask your GP to write a referral to that specific provider [2]. |
| 4 | Complete the Assessment | The specialist will conduct a multi-source evaluation: <br>• Clinical interviews about your life and childhood history (ADHD symptoms must appear before age 12) [5][11]. <br>• Corroboration: They may interview a partner, family member, or friend to confirm symptoms [3][9][12]. <br>• Rating scales & tests: Tools like the Conners Test or neuropsychological tests to measure attention and memory [4][9][10]. <br>• Rule-outs: A physical exam to exclude medical issues (e.g., sleep problems, anxiety, depression) that mimic ADHD [1][5][11]. |
| 5 | Receive Diagnosis & Plan | The provider compares your results against DSM-5 criteria to confirm if you meet the diagnosis. If diagnosed, they will develop a treatment plan (medication, therapy, or lifestyle changes) [3][5][9]. |
Who Can Diagnose You?
- Psychiatrist: A medical doctor who can diagnose ADHD and prescribe medication [2].
- Psychologist: Can diagnose ADHD and provide therapy/testing but cannot prescribe medication (in most regions) [2].
- Primary Care Physician (GP): Some can diagnose and treat ADHD, though many refer to specialists for complex cases [5][7][10].
- Nurse Practitioner: Some can also diagnose and manage ADHD treatment [10].
Important Notes
- Childhood History is Critical: ADHD is a neurodevelopmental disorder that begins in childhood; you must demonstrate that symptoms were present before age 12, even if they weren’t diagnosed then [5][11].
- No "Pass/Fail" Tests: Rating scales and psychological tests are not exams you pass; they simply help clarify your symptom pattern [5].
- Public vs. Private Systems: In countries like the UK, you can access assessment through the NHS (public) by seeing your GP, though wait times can be long; private assessments are faster but cost more [2][6].
If you are unsure where to start, the CDC recommends talking to a healthcare provider as your first step to determine if your symptoms fit an ADHD diagnosis [11].
