Common adult patterns
Attention
Losing track in meetings, reading without retaining, overlooking detail, or struggling to sustain effort on low-reward tasks.
Executive function
Difficulty sequencing tasks, prioritising, starting, switching, remembering intentions and completing multi-step work.
Time and urgency
Underestimating duration, relying on last-minute pressure, or becoming absorbed in one activity at the expense of others.
Impact
The same underlying difficulties may show up in work, education, finances, relationships, driving, sleep routines or household management.
Why childhood history matters
ADHD is developmental. A proper assessment therefore looks for evidence that relevant difficulties were present earlier in life, even if they were not recognised as ADHD at the time.
What can look similar
Sleep problems, anxiety, depression, trauma, autism, substance use, physical illness and severe stress can all affect concentration or executive function. These possibilities may coexist with ADHD and need careful consideration.
