I think I have ADHD as an adult. How do I get diagnosed?

To get diagnosed with adult ADHD, you should start by talking to your primary care physician (GP) who can refer you to a specialist like a psychiatrist or psychologist for a comprehensive clinical evaluation[1][2]. Since there is no single medical or genetic test for ADHD, the diagnosis relies on a detailed assessment that includes interviews, symptom checklists, and collateral information from family members[3][5][8].

Here are the specific steps to follow:

1. Self-Reflection and Initial Screening

Before seeing a doctor, check if your symptoms affect two or more areas of your life (e.g., work, school, home) and noticeably interfere with your functioning[1]. You can take an online Adult ADHD screener (such as the ASRS) to better understand your symptoms, but do not self-diagnose[1][2][3].

2. Consult Your Primary Care Physician

Have an open conversation with your GP about why you suspect you have ADHD. Explain your concerns, any other mental health issues, and how these symptoms impact your daily life[2]. Your doctor may:

• Perform a physical exam and hearing/vision tests to rule out other conditions like thyroid issues or sleep disorders[5][8].
• Refer you to a specialist for a full assessment[1][2][6].

3. Complete a Comprehensive Specialist Evaluation

A qualified specialist (psychiatrist, psychologist, or nurse) will conduct a detailed evaluation that typically includes:

• Diagnostic Interview: A discussion about your current symptoms, daily struggles, and childhood history (symptoms must have started before age 12)[1][3][5].
• Behavioral Rating Scales: Questionnaires like the ASRS, DIVA, or CAARS to measure symptom severity[3][5].
• Collateral Information: Interviews with family members, partners, or old report cards to confirm symptoms and childhood onset[1][3][5].
• Assessment of Co-existing Conditions: Checking for anxiety, depression, or learning disabilities that may mimic or worsen ADHD[3][7].

4. Meet Diagnostic Criteria

According to DSM-5, adults must present with at least five symptoms of inattention or hyperactivity/impulsivity for six months or longer, occurring in two or more settings, and causing measurable impairment[3][6][7].

Where to Find a Specialist

• Ask your GP for a referral[1][2].
• Search directories for doctors specializing in ADHD[1].
• Contact organizations like CHADD, ADDA, or ADD.org for support and specialist recommendations[1][6].
• Look for university-based hospitals or medical schools in psychology departments[6].

If you are in the UK, you can ask your GP to refer you for an NHS ADHD Assessment, but be aware that waiting lists can be long, so you may consider private options if needed[2].

Brands and Services to Consider:

• CHADD (Children and Adults with Attention-Deficit/Hyperactivity Disorder): A leading US organization offering support and specialist referrals[6].
• ADD.org: Provides resources and a step-by-step guide for diagnosis[1].
• ADDA (Attention Deficit Disorder Association): Supports adults with ADHD and can help find specialists[1].
• Cleveland Clinic: Offers clear ADHD screening protocols and specialist evaluations[7].
• CDC: Provides official diagnostic guidelines and resources[8].

Important Note: You do not need to have been diagnosed as a child to be diagnosed as an adult, but you must have had symptoms before age 12[3][6]. The process usually requires at least two visits to confirm persistence and rule out other explanations[3].
