What is the difference between ADHD and just having poor concentration?
The short answer
Poor concentration has many causes — poor sleep, chronic stress, phone addiction, depression, thyroid dysfunction, boredom. ADHD is specifically a neurodevelopmental condition with a genetic basis, measurable neurological differences, and a characteristic developmental history beginning in childhood.
The data
| Feature | ADHD | Situational poor focus |
|---|---|---|
| Onset | Childhood (before age 12) | Any age |
| Consistency | Pervasive across settings | Situation-specific |
| Hyperfocus | Often present (ADHD paradox) | Rarely |
| Response to stimulants | Significant improvement | Modest or none |
| Genetic component | Strong (heritability ~80%) | Variable |
| Underlying cause | Neurobiological | Sleep, stress, environment, depression |
What it means for you
Before attributing poor focus to ADHD, it's worth addressing sleep, phone use, stress, and exercise — these alone can produce dramatic attention improvements. The Attention test gives an objective baseline. If your score is consistently well below average despite good sleep and low stress, that's worth discussing with a clinician.

Quick Answer
ADHD is a neurodevelopmental condition with genetic basis and measurable neurological differences (especially in dopamine and norepinephrine systems). Poor concentration can have many causes: poor sleep, stress, phone addiction, boredom. The key differentiator is pervasiveness and developmental history.
