Adult ADHD
Adult ADHD (attention-deficit/hyperactivity disorder) describes enduring difficulties with attention, organization, restlessness, or impulsivity that begin in childhood and continue to interfere with work, relationships, or daily tasks.
Definition
Attention-deficit/hyperactivity disorder in adults is a neurodevelopmental condition marked by persistent inattention and/or hyperactivity-impulsivity. Symptoms must have been present before age 12 and cause impairment in more than one setting. Self-report screeners such as the ASRS help flag when a full clinical evaluation may be useful; they do not diagnose ADHD.
What it can feel like
- Chronic procrastination and difficulty finishing projects.
- Losing keys, appointments, or steps in a task.
- Feeling internally restless or talking over others.
- Difficulty sustaining focus during meetings, reading, or conversations.

Frequently asked questions
Can adults be diagnosed with ADHD if they were not diagnosed as children?
Yes. Many adults were missed in childhood. Clinicians look for a lifelong pattern of symptoms, not only current struggles.
What is the ASRS v1.1?
The Adult ADHD Self-Report Scale (ASRS v1.1) is an 18-item WHO-supported screening tool for ADHD symptoms in adults.
Does a high ASRS score confirm ADHD?
No. ADHD diagnosis requires comprehensive clinical assessment, including history, impairment, and rule-out of other conditions such as anxiety or sleep disorders.
