ADHD may be less a deficit of attention than a difficulty sustaining engagement. Psychiatrist Awais Aftab argues that the distinction is not semantic: it changes how we understand distraction, boredom, time blindness and why stimulants help.
In neuroscience, attention has a relatively narrow meaning — selecting relevant information while filtering out interference. Many experiences associated with ADHD are different. Losing the thread of a conversation, failing to begin a tedious task or abandoning one before it is finished involves keeping the mind attached to something over time. The question may not be whether a person can identify what matters, but whether the task continues to register as worth doing.
Aftab points to a 2025 brain-imaging study of children taking stimulants. The medications altered networks involved in salience, reward and arousal, but the researchers did not detect changes in attention networks, with or without an ADHD diagnosis. One interpretation is that stimulants make mundane activities feel more significant. A restless child can then remain with schoolwork rather than search for stimulation elsewhere.
More than one route to the same diagnosis
That account fits decades of research that has resisted a single-deficit model. Edmund Sonuga-Barke’s work proposed several possible pathways, including aversion to delay, difficulty stopping an action and disrupted tracking of time. Russell Barkley emphasized behavioral inhibition, working memory, motivation and emotional regulation. His idea of “time blindness” describes a shortened psychological horizon in which future consequences carry too little weight in the present.
None of these capacities produces a clean diagnostic test. No one neuropsychological abnormality appears in everyone with ADHD, and none belongs exclusively to ADHD. The category can be real and disabling without reducing to one broken mental faculty.
The name still has consequences. Someone whose main problems are lateness, boredom, emotional volatility or needing deadline pressure to begin may not recognize those experiences as an “attention deficit.” At the same time, widening the frame raises a legitimate question: when does difficulty tolerating repetitive work become a medical disorder rather than a mismatch between a person and an environment?
Aftab rejects the choice between blaming the brain and blaming modern life. Impairment emerges from their interaction. Contemporary work rewards multitasking and prolonged tolerance for dull administrative labor, while phones and social platforms make interruption constant. Those conditions can make a pre-existing vulnerability more disabling without making the vulnerability imaginary.
That middle position matters. ADHD is not merely a social label, and treatment is associated in observational studies with lower rates of death, self-harm, transport accidents, criminal convictions and substance misuse. But treatment need not imply that every source of impairment sits inside the individual. A more accurate model asks both what helps a person regulate engagement and what demands we have decided everyone should be able to endure.
