I Think I Have ADHD: Adult Symptom & Diagnosis Guide

ADHD symptoms do not magically disappear with puberty. In fact, roughly two-thirds of all children with ADHD grow up to be adults with ADHD. But many still don’t know it. Because the medical community’s understanding of inattentive vs. hyperactive attention deficit, and the unique manifestation of symptoms in girls vs. boys, has improved so markedly in the last few decades, many adults are recognizing their ADHD symptoms for the first time in their 30s, 40s, 50s and even 60s.

If you suspect that your lifelong struggles with memory, focus, or friendships may actually trace back to attention deficit hyperactivity disorder (ADHD or ADD), this slideshow will guide you through the process of diagnosis, treatment, and moving on.

More often than not, the hyperactivity that we often associate with ADHD fades with childhood. As we age, symptoms tend to manifest as failure to pay attention to details, trouble organizing and completing big tasks, forgetfulness, talking before thinking or rudely interrupting, or feeling overwhelmed in crowds and stores. Too often, the shame that we feel at failing to manage these unidentified symptoms is diagnosed as anxiety or a mood disorder; the ADHD link is missed entirely.

If you suspect ADHD symptoms are at play, take this adult ADHD test.

ADHD is not a behavior disorder. It is a developmental impairment of the brain’s self-management system — a neurological condition that impacts executive functions. Finding a medical professional who understands this, and knows how to recognize symptoms in adults, is half the battle.

During an initial consultation, you should expect your doctor to review the ADHD criteria in the Diagnostic and Statistical Manual of Mental Disorders-V (DSM-V). Intelligence tests, broad-spectrum scales, computer tests, and even brain scans may follow to ensure an accurate diagnosis. The most vital step is to find a doctor who’s qualified to diagnose ADHD.

About 80 percent of individuals with ADHD are diagnosed with at least one other psychiatric condition at some time during their lives. A comorbid, or related, condition is a second separate condition that exists alongside ADHD, and needs to be treated in conjunction with attention deficit.

The most common ones for adults are mood disorders, generalized anxiety, sleep disorders, OCD, and sensory processing disorder. In the cases where these conditions are secondary to ADHD — in other words, untreated symptoms of ADHD bring them on or exacerbate them — treating your attention deficit will make a world of difference.

You’re 45 years old and your doctor just diagnosed you with ADHD. Your first emotion is likely relief. Finally, you have an answer — an explanation for why so many things were so inexplicably difficult for so long.

Then you're hit with regret. Why did you have to struggle for so long? How would life have been different if you’d been diagnosed as a child? And then there’s the lifetime of ADHD shame to overcome. After so many years of lost keys, missed appointments, and broken promises we learned to blame ourselves for being weak or undisciplined or just not good enough.

Psychiatrists. Psychologists. Neurologists. General care physicians. Nurse practitioners. And counselors. All of these ADHD professionals can all diagnose and treat symptoms of ADHD, but different professionals specialize in different solutions — and cost different amounts. To pursue a treatment plan using ADHD medication, you need to see a doctor or psychiatrist. If your family life is strained, a psychiatrist or ADHD coach may be able to provide realistic solutions to daily problems. Treatment plans and professionals are not one-size-fits-all; research is key.

What’s the difference between a stimulant and a non-stimulant? How long do ADHD medications take to kick in? What are the most typical side effects? What drug interactions should I avoid? Will it make me feel like a zombie or dampen my creativity? How expensive are they?

Your questions about treating ADHD symptoms with medication probably go on and on. The good news is that after decades of testing and safe use, the medical community has answers for nearly all of them. Begin finding ADHD medication answers here.

Daily food choices alone can neither cause nor cure ADHD symptoms. But studies do show that foods low in sugar and additives, and high in protein and vitamins can help with focus, attention, energy, and even memory. In addition, omega-3 fatty acids have been shown to improve impulsivity and concentration. And iron, zinc, and magnesium — often naturally low in people with ADHD — can improve mental and physical health.

Physical activity stimulates the release of compounds your brain loves, promotes new brain-cell growth, and keeps the brain operating a peak efficiency. These are just a few of the reasons — besides the obvious appearance management ones — why exercise should be part of your ADHD treatment plan. But did you know that meditation and brain training have proven benefits as well? That yoga and mindfulness can help to keep symptoms in check on a daily basis?
