When we think of attention-deficit/hyperactivity disorder (ADHD), we imagine a child who is disruptive in school. But ADHD, is far less apparent in adults diagnosed with the condition. Result: Adult ADHD often goes undiagnosed. Here are the symptoms to look out for…

Inattentiveness and disorganization. Adults with ADHD struggle with poor focus and/or have cluttered homes and workspaces. They make careless mistakes on paperwork or forget important details. They may have trouble staying attentive in conversations and feel scattered and overwhelmed, and seemingly simple aspects of life cause them endless struggles. Example: There’s always a pile of unopened bills waiting to be paid.

Restlessness and impulsivity. Adults with ADHD generally have enough self-control to avoid displaying disruptive behavior—but the impulsive tendencies are still there under the surface. These adults might find it hard to relax, talk excessively and/or make rash decisions.

Executive function deficits. Adults who have ADHD often struggle to plan tasks and/or have trouble setting a work pace that allows them to complete tasks by deadlines. Time management, procrastination and managing emotions can be big issues at work or at home.

Even after identifying the symptoms above, diagnosing adult ADHD isn’t always straightforward. Also consider…

How often these symptoms affect your life. Symptoms won’t just appear occasionally—they will be consistent trends in your life and show up across different contexts. Also think about when your symptoms appear—if it’s usually during times when you’re anxious and/or struggling with sleep, then that could be the main driver of ­inattention or restlessness.

How long these symptoms have been part of your life. An adult who has ADHD was a child who had ADHD. Your childhood ADHD might have gone undiagnosed, but you should see evidence of it when you reflect back. Did you chronically procrastinate with your homework? Did you daydream in class and often miss what teachers said?

Also: People who have ADHD are at increased risk for depression, anxiety and/or substance abuse, so having a ­history of any of these can be a clue.

If you suspect you have ADHD: Take the free adult ADHD screening test available on the Attention Deficit Disorder Association’s website (on ADD.org, select “ADHD Test” from the “Start” menu). For more information: Visit the website of CHADD (CHADD.org) or ADDitude Magazine (AdditudeMag.com).

If the screening test suggests you could have adult ADHD, ask your ­primary care physician or therapist for a referral to a specialist who can perform a more precise screening, or look for a specialist using the Professional Directory on ADD.org.
