Attention Deficit Hyperactivity Disorder

A neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning and development. ADHD affects approximately 7.6% of children and 6.8% of adults worldwide and has three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. In digital accessibility, ADHD creates distinct challenges including difficulty sustaining attention through long content, susceptibility to visual and auditory distractions, challenges with information processing pace, and difficulty with complex multi-step navigation. Historically underdiagnosed in women, adults, and people of color due to diagnostic biases.
