ADHD: a lack of focus or dysregulated focus? What the literature says about being unable to disengage from an engaging task

What is being measured in ADHD is not an absence of focus: hyperfocus scores in 132 adult patients at two clinics were higher than in controls.

🧠 Ozel-Kizil et al. describe hyperfocus as an inability to shift attention away from an engaging event and write that it could be defined as a distinct dimension of adult ADHD. No difference was found between 79 patients taking psychostimulants and 53 patients who had never taken them. In a qualitative study of young adults, most participants said that the diagnostic criteria did not capture their experiences and that what they experienced was dysregulated attention, including hyperfocus.

🔬 In terms of performance, the distinguishing finding is variability, not slowness: in a meta-analysis of 319 studies, the difference in reaction time variability had an effect size of 0.76 in children and adolescents and 0.46 in adults, and adults could not be distinguished from other clinical groups. In terms of motivation, dopamine measurements in the reward pathway were associated with motivation scores in 45 adults with ADHD; this is a correlation, and that study did not measure hyperfocus. There is also evidence to the contrary: 78 patients with ADHD did not differ from matched controls on measures of hyperfocus, and the authors write that hyperfocus is not specific to ADHD.

🧭 Here are some areas to work on: do not leave feedback until the end, divide large tasks into smaller parts with shorter waiting periods, do not judge yourself based on a single day, and write down a stopping time in advance when you become focused. Consult a physician if your functioning is impaired: in a network meta-analysis of 113 randomized trials, stimulants and atomoxetine showed consistent effects on both patient- and clinician-rated scales, while results for non-pharmacological interventions varied depending on who rated them.
