How often do ADHD and anxiety occur together?
Quick answer: Anxiety co‑occurs in ~40–60%. Address both: skills for worry and avoidance, plus ADHD time/organization systems. Treating anxiety often improves follow‑through and reduces conflict.
Large surveys and clinical samples find elevated rates of anxiety disorders among adults with ADHD. Depending on the method and population, around 40 to 60% of adults with ADHD meet criteria for an anxiety disorder at some point. Anxiety can compound attention and executive challenges, and vice versa.
A clinician can separate primary drivers and outline a plan that addresses both patterns.
