ADHD isn't only a childhood condition. The adult presentation looks different — and is widely underdiagnosed.
Adult ADHD is the disorder most likely to be missed in primary care. The clinical literature suggests that as many as 60% of children with ADHD continue to have meaningful symptoms in adulthood, yet adult diagnosis rates remain a fraction of the prevalence.
It doesn't look like the childhood version
Hyperactivity in adults usually presents internally: restlessness, racing thoughts, difficulty sitting through long meetings, a constant low-grade need to be doing something. The visible "can't sit still" of childhood often softens into a feeling that's only obvious to the person experiencing it.
Inattention, on the other hand, tends to amplify. The cognitive load of adult life — work, finances, family, scheduling — exposes attention difficulties that were masked by structured childhood routines.
What to watch for
Chronic difficulty starting tasks (even ones you want to do), losing track of conversations mid-sentence, frequent missed deadlines despite real effort, time blindness, and emotional dysregulation (low frustration tolerance, big reactions to small setbacks). The adult ADHD pattern is usually a long history, not a recent change.
Why it gets missed
Adults with ADHD often build sophisticated workarounds — perfectionism, last-minute panic productivity, over-reliance on calendars and reminders. The workarounds look like high-functioning behavior from outside. Inside, they're exhausting.
Getting screened
The ASRS-v1.1 is the standard adult ADHD screening — six questions for the first pass. Sayf clinics can send it via SMS through the BHI program. Your physician reviews the result. If a fuller evaluation is warranted, we coordinate the referral.
