Screen for attention, hyperactivity, and executive function patterns in adults.
ADHD (Attention-Deficit/Hyperactivity Disorder) affects approximately 4.4% of adults worldwide, yet many remain undiagnosed. This screening tool assesses common ADHD symptoms including inattention, hyperactivity, impulsivity, and executive function challenges to help you determine if further evaluation may be beneficial.
ADHD was long considered only a childhood disorder, but research over the past 30 years has established it as a lifelong neurodevelopmental condition. The ASRS (Adult ADHD Self-Report Scale), developed by the World Health Organization, revolutionized adult ADHD screening in the early 2000s. Our checker draws from this and other validated instruments. Notably, ADHD brains show structural differences in the prefrontal cortex and dopamine pathways, explaining difficulties with attention regulation and executive function.
Rate 10 statements about attention, organization, and impulsivity on a frequency scale.
The screener captures both inattentive and hyperactive-impulsive symptom clusters.

Your overall ADHD symptom severity score
Inattention patterns — difficulty focusing, distractibility, forgetfulness
Hyperactivity-impulsivity patterns — restlessness, interrupting, impatience
Executive function challenges — planning, organizing, time management
Whether professional ADHD evaluation is recommended
ADHD is a neurodevelopmental condition with strong genetic heritability (~74%). Neuroimaging studies show differences in prefrontal cortex activity and dopamine regulation. Validated screening tools like the ASRS have sensitivity rates of 68.7% and specificity of 99.5% for identifying ADHD in adults.
