How is ADHD diagnosed in Adults / over 18’s?
ADHD can not be determined by a single psychological test.
An ADHD diagnosis is made through a clinical assessment process which involves several steps.
During the assessment you will be asked various questions and complete a number of psychological tests.
You will complete an objective computer tests which will compare your performance to against age-matched individuals. This improves the diagnostic accuracy and helps to tailor treatment.
The assessment process will obtain additional collateral input. A parent, partner, spouse, sibling, or any other person that knows you well can complete questionnaires on your behalf or assist in the interview (where possible). Information may also be obtained via school and medical reports.

The assessment will also screen for possible other conditions which often occur with ADHD.
