How sure the science is
Guideline advice, not formally graded, ADHD evidence
Recommended by ADHD clinical guidelines, but nobody has pooled the trials and graded how sure they are. Guideline advice is a considered judgement, not a measured certainty. Measured in people with ADHD.
NICE NG87 1.2.10 recommends specialist assessment for adults meeting its criteria; NHS guidance agrees; no GRADE rating for the pathway.
The number, drawn
Seek help when symptoms affect study, work or relationships
Why it matters
ADHD assessment looks at how symptoms affect your life now and whether they were present in childhood. Interviews, health history and information from someone who knows you help distinguish ADHD from other explanations. NHS guidance supports seeking help when difficulties affect work, study or relationships, and NICE recommends specialist assessment when symptoms began in childhood, have persisted and cause at least moderate impairment. This is a care recommendation, not a measured percentage benefit.
How to do it
- Tell your primary care clinician which everyday difficulties made you seek help.
- Bring examples from your life now and from childhood, plus any school reports you already have.
- Note down sleep problems, mood symptoms, other health conditions and medicines for the assessor.
- Ask who assesses adult ADHD locally and what support you can get while you wait.
An online screener cannot confirm ADHD. A qualified clinician has to weigh your symptoms, impairment and other possible causes.
Putting it into practice
In real life
- Bring one example from work and one from childhood, even if they are about different difficulties.
- Ask whether someone who knew you as a child can add what they remember.
Watch out for
- Common mistakeWaiting until your records are perfect can delay help. Bring what you have and talk about the gaps.
- Common mistakeA quiz score can start the conversation, but a clinical assessment has to look at your history.
