Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that persists from childhood into adulthood, with current diagnostic methods being time-consuming and reliant on subjective recall and clinician judgment. Researchers conducted a retrospective study to determine if physiological measures such as Electrodermal Activity, Heart Rate Variability, Skin Temperature, neuropsychological assessments, and imaging techniques can reliably identify adult ADHD.
