Difficulty concentrating has many possible causes. Poor sleep, depression, anxiety, prolonged stress, substance use and certain physical illnesses may resemble ADHD. At the same time, ADHD can coexist with other mental health conditions. This is why a thorough assessment takes more than a quick screening test. [1]

A specialist asks not only whether concentration is difficult, but when the difficulties began, whether they were present in childhood, in which settings they occur and how they affect work, home and relationships. Previous records and information from people familiar with the person’s development may be useful. Questionnaires support clinical judgement; they do not replace it. [2]

Sometimes the assessment concludes that ADHD is not the most accurate explanation. That is not a failure. A precise understanding opens the door to more appropriate help. Good diagnosis is about seeing the person behind the symptoms, not securing a particular label at any cost. [3]
