Though attention-deficit/hyperactivity disorder (ADHD) is often diagnosed in children, it sometimes isn’t recognized until adulthood. A person may experience symptoms like impulsivity, hyperactivity, and inattention for years until someone begins to suspect ADHD is the cause.
If you’re an adult and think you might have ADHD, your first instinct may be to contact your primary care physician or family healthcare provider (HCP). It’s a wise choice. Your HCP knows your medical history and medications you're taking. They may be in a good position to rule out other health conditions that can look like adult ADHD, such as thyroid problems, seizure disorders, and liver trouble.
But an HCP frequently needs additional input for an ADHD diagnosis. After listening to your symptoms and narrowing down the possibilities, they may refer you to a psychiatrist for further evaluation.
The role of a psychiatrist in adult ADHD
Because diagnosing adult ADHD can be tricky, a psychiatrist is often better suited than a family HCP to give you an accurate diagnosis. You may be uncomfortable with the idea of seeing a psychiatrist, but there are many reasons you should feel at ease. Seeing a psychiatrist doesn't mean you're "crazy." They are simply doctors who specialize in treating conditions that affect brain chemistry and brain function, such as ADHD.
A psychiatrist can help diagnose, treat, and manage ADHD symptoms so they don't interfere with your job performance, relationships, or personal goals. They often know a great deal about ADHD medications, their side effects, and how to monitor and adjust them. If it's possible to find a psychiatrist who specializes in ADHD, all the better.
Psychologists and neurologists are also qualified to diagnose ADHD. If you see a psychologist, keep in mind that he or she won't be able to prescribe medication, if needed.
How an adult ADHD diagnosis is made
For a diagnosis of adult ADHD, a pattern of symptoms must have been present before age 12. These symptoms must have disrupted your daily life in at least two different places, such as work and school.
To begin your evaluation, a psychiatrist or other HCP will ask several questions about your symptoms and behavior as a child up through the present day. They may pull in people who know you well, such as your partner or family members. Your loved ones can help fill in details about your behaviors over the years.
Diagnosis may also involve:
- Tests to evaluate your thinking, planning, and decision-making skills
- Rating scales and symptom checklists that have been developed to look specifically for signs of adult ADHD
- Evaluating your mental health condition, to find or rule out disorders like depression and anxiety
The faster you receive an accurate diagnosis, the sooner treatment can begin and the better you’ll feel. If you suspect adult ADHD, see an HCP as soon as you can to get started.
