Losing your train of thought, rereading the same paragraph, missing deadlines you meant to hit: trouble focusing is one of the most common reasons adults look for help. ADHD is one possible cause, but it is far from the only one, and the right answer depends on finding the real reason.
Common causes of poor focus in adults
- Poor or short sleep, including sleep apnea, which often goes unnoticed
- Anxiety, which keeps the mind busy with worry
- Depression, which slows thinking and drains motivation
- Chronic stress and burnout
- Medical conditions such as thyroid problems or anemia
- Side effects of medicines you already take
- ADHD, which usually shows signs back to childhood and affects more than one part of life
