Assessed for ADHD and autismtogether, not one at a time.
Traits of ADHD and autism are routinely mistaken for each other. A combined assessment looks at both, so you get the whole picture rather than the half that fits one diagnosis.

One diagnosis that explains most of it, but not all
Until DSM-5 was published in 2013, the diagnostic manual did not allow ADHD and autism to be diagnosed in the same person. Clinicians assessed for one and stopped. That restriction has been gone for over a decade, but a great many adults were assessed under it — and plenty of services still run the two as entirely separate pathways with separate waiting lists.
The practical result is a familiar pattern: a diagnosis that explains a lot but leaves things unaccounted for. The social exhaustion that the ADHD label does not quite cover. The executive dysfunction that the autism label does not quite cover. Traits overlap heavily — difficulty in social situations, sensory overwhelm, burnout, trouble starting tasks — and a clinician assessing for one condition interprets everything you describe through that lens.
Being assessed for both at once avoids that. It costs more and takes longer, because it genuinely is more work. What it buys is a picture that accounts for all of it.
Inside a combined ADHD and autism assessment
Clinics vary in what they include, and the difference is rarely obvious from a price. These are the stages a thorough assessment covers, and the instruments a CQC-registered clinic should be able to name when you ask.
Screening
ASRS v1.1 · AQ-10A short, validated self-report questionnaire. The ASRS v1.1 was developed with the World Health Organization; the AQ-10 is the autism equivalent used in UK primary care. Screening indicates whether a full assessment is likely to be worthwhile. It is self-completed and is not a diagnosis, a triage decision, or a clinical opinion.
Pre-assessment history
Clinics gather developmental history before the appointment — school reports, and where possible an account from a parent, partner or someone who knew you as a child. ADHD and autism are lifelong, so evidence that traits were present in childhood matters to the diagnostic criteria.
Diagnostic interview
DIVA-5 · ACE+ · ADOS-2The assessment itself: a structured clinical interview lasting roughly 60–90 minutes, conducted by a psychiatrist or specialist practitioner. DIVA-5 is the standard structured interview for adult ADHD; ADOS-2 and ADI-R are used in autism assessment. Some clinics add an objective computerised measure such as QbTest or MOXO, which records attention and movement against a control group.
Report and outcome
NICE NG87A written diagnostic report setting out what was assessed, the outcome against DSM-5 or ICD-11 criteria, and recommendations. NICE guideline NG87 governs ADHD diagnosis and management in the UK, and a report written to it is what a GP will expect to see.
After a diagnosis
Titration · shared careIf medication is recommended, titration is the supervised period — usually several weeks — of adjusting dose and monitoring response, heart rate and blood pressure. Ongoing prescribing often depends on a shared care agreement between the clinic and your GP. Whether a GP enters one is at their discretion and at their ICB’s, and it is never guaranteed. Ask any clinic what happens if your GP declines, before you book.
ThinkBetter is a marketplace, not a clinical service. The assessment is carried out by the independent clinic you choose, and any diagnosis is theirs to make.
