Combined Autism and ADHD Evaluation for Adults

An AuDHD assessment for adults who never fit one label

You have probably been assessed before, for one thing, by someone who was not looking for the other. This is a single evaluation that examines autism and ADHD in the same person, by video, with a licensed psychologist, ending in a written report you own. 100% private-pay. Nationwide.

Start Therapy How it works

The short answer

An AuDHD assessment is one clinical evaluation that examines autism and ADHD in the same adult, instead of screening for one condition and stopping there. CEREVITY delivers it by video with a licensed psychologist and produces a written clinical report. Care is entirely private-pay, so no insurance claim is filed and no carrier ever holds a diagnosis code for you.

The question that stalls the booking

If this ends up on paper, where does the paper go?

Adults delay evaluation for one reason above all others: not the fee, not the hours, but a fear of what a written finding might later do to a career, a custody file, or an application nobody has invented yet. Here is precisely what exists after a CEREVITY evaluation, and what never does.

No claim, no carrier record
You pay privately, so nothing is submitted to an insurer. No claim is filed, no billing diagnosis code is generated, and no third party ends up holding a file that says what you were evaluated for or what the clinician concluded about it.
The report has one holder
Your written report and the raw scoring behind it stay with the licensed clinician who conducted the evaluation, protected by HIPAA and legal privilege. Release happens on your written authorization, apart from the narrow legal exceptions your clinician names at intake.
What we will not tell you it does
No honest clinician can promise that a given organization will accept a private evaluation, and no conclusion is settled before the work is done. What a school, an employer, or an agency asks for is theirs to define and it changes; ask them in writing first, then bring their answer to intake.

What sends adults to an AuDHD assessment

Rarely a crisis. Six things clinicians hear from people who have already been through the system once and came out with half an answer.

A diagnosis that only ever half-fit

Someone gave you ADHD at 29 and the stimulant conversation went nowhere near the sensory overload, the scripting before phone calls, or why an unplanned change to Thursday ruins Wednesday.

Fifteen years aimed at the wrong target

Anxiety treatment, then depression treatment, then a sleep protocol. Each one plausible, each one working on the smoke while the fire kept its own schedule underneath.

AuDHD symptoms that pull in opposite directions

You need routine and you cannot tolerate boredom. You crave novelty and it wrecks you. The two profiles are not politely taking turns; they are arguing, and nobody has named the argument.

Your child's evaluation read like your own childhood

You sat through a school meeting about your daughter and recognized every line of it. That recognition is one of the most common routes adults take to their own assessment.

Burnout that rest does not touch

Two weeks off, and you came back just as flattened. Effort spent holding a presentable version of yourself in place does not refund itself on a beach.

An AuDHD test result you cannot act on

An online AuDHD test told you that you scored high on both. It could not tell you whether that is true, what else explains it, or what you are supposed to do next.

Inside an AuDHD assessment: what the evaluation actually does

A structured clinical evaluation over several appointments, ending in a report and a conversation about it. Not a quiz, not a single questionnaire, not a hunch.

Developmental history first, instruments second

Adult self-report on its own is thin evidence, because you have spent decades editing yourself. The evaluation starts with a full developmental and functional history: early schooling, friendships, sensory life, work patterns, what you have been compensating for and at what cost. Where it helps and you consent, a parent, sibling, or partner is invited to add what they remember.

Standardized instruments come next, chosen for what the history raises, and they are scored rather than eyeballed. Autism and ADHD are then weighed against each other and against the conditions that mimic both: anxiety, trauma, mood disorders, disrupted sleep. The point is not to stop at the first plausible fit, which is how most adults ended up with half a diagnosis in the first place.

What the evaluation has to correct for in women and in men

AuDHD in women is under-recognized, and the clearest evidence for that is how fast the recognized ratio is moving. In a statewide North Carolina cohort of more than ten thousand people evaluated between 2000 and 2021, the male-to-female ratio of autism diagnoses fell from 5.64:1 to 3.07:1, and girls in that sample were diagnosed later than boys. AuDHD symptoms in women more often present as internalized distress, exhausting social camouflage, and inattentive rather than hyperactive ADHD, none of which trips the referral pathways built around disruptive boys.

AuDHD in men carries a different error. Hyperactive and externalizing traits get noticed early, an ADHD label lands, and the autism side is never examined again; the report reads complete and the sensory and social difficulties keep going unexplained. Two honest caveats belong here: most of this literature studies children rather than adults, and the sex differences it describes are group patterns, not a rule about you. Your evaluation is built from your history, not from a profile.

A written report, then a plain conversation about it

You receive a written clinical report: what was administered, what the scores showed, the clinician's diagnostic conclusions and their confidence in them, and where the picture stayed genuinely unclear. Ambiguity gets written down rather than smoothed over, because a report that overclaims is worth less than one you can rely on.

Then you sit with the clinician who wrote it and read it together. That session covers what the findings mean for how you work, rest, and relate, and what kind of ongoing therapy would follow if you want it. CEREVITY clinicians are psychologists and therapists; they do not prescribe, so anything to do with medication belongs to you and your prescribing physician.

AuDHD testing or an online screener: what separates them

A screener sorts you into a bucket. A licensed evaluation explains you, in writing, with someone's name on it.

	CEREVITY Assessment	Online AuDHD Screeners
Who conducts it	A licensed doctoral-level clinician who takes the history, scores the instruments, and signs the report	An automated scoring script; no clinician reads your answers
What gets examined	Autism traits, ADHD traits, and the alternatives that imitate both, weighed against each other	One trait list, checked only against itself
What you walk away with	A written clinical report, plus an appointment spent reading it with the clinician who wrote it	A score, a bar chart, and a suggestion to see somebody
Insurance footprint	None; private-pay creates no claim and no carrier-held code	None, and no clinical record either
Choose it when	You need conclusions a clinician will put their name and license behind	You are curious and want a starting point to bring to a clinician

Concierge by design: you are matched, never left to browse

One conversation about what you actually need examined. One deliberate match to a clinician who does adult evaluations.

Confidential intakeA single coordinator takes your intake personally and stays with it, from your first note through the appointment where the report is read.

Matched to a specialistYou are matched on clinical fit for adult neurodevelopmental evaluation, not on whoever happens to have a gap in the calendar.

Matched the same dayMatching happens the same day, often within the hour, and appointments run seven days a week from early morning to late evening, so a long history-taking session does not have to consume a working day.

Measured progressThe standardized measures used in the evaluation are scored and reported to you; if you continue into therapy afterward, they are re-administered, so change shows up on paper instead of in memory.

Where we practice: nationwide. Coverage is nationwide: CEREVITY psychologists hold PsyPact authority across the member states and individually licensed clinicians cover the rest, matched to wherever you are physically sitting during each appointment. There is no clinic to be seen walking into, which for this particular evaluation is often the point.

One recovery, one story

“

I had been treated for anxiety and then depression for fifteen years. I scored high on both scales of an online AuDHD test and finally asked for one evaluation that looked at autism and ADHD together. The earlier diagnoses were not imaginary. They were incomplete. One assessment that held both changed which tools we used and which stories about myself I could finally retire.

What adults ask before booking AuDHD testing

Is AuDHD an actual diagnosis?

No, and the history matters. AuDHD is a community coinage for co-occurring autism and ADHD; you will not find it in any diagnostic manual. What you will find is the pair, because DSM-IV's exclusion criteria barred clinicians from diagnosing ADHD alongside a pervasive developmental disorder such as autistic disorder, and DSM-5 removed that bar in 2013. Adults over roughly forty were assessed under a system that was not allowed to give them both.

Will this evaluation get me a prescription?

No. CEREVITY clinicians are licensed psychologists and therapists, and they do not prescribe. The evaluation produces a clinical report and a conversation about what the findings mean; anything to do with medication is a decision between you and a prescribing physician, and this page offers no guidance on it. You are free to take the report to that appointment.

Will an employer, a school, or a licensing body accept the report?

That is genuinely not ours to answer, and we will not pretend otherwise. Requirements differ between organizations, they are revised without notice, and no clinician can promise that a private evaluation will satisfy a particular body's current criteria. Ask them directly, in writing, before you book, and where the stakes are high ask your own counsel. Bring whatever they tell you to intake so the evaluation is planned with it in view.

How do AuDHD symptoms in women differ from AuDHD in men?

Group patterns exist, and they are patterns rather than rules. Women more often present with inattentive ADHD, internalized distress, and heavy social camouflage that hides autistic traits from the people who might have referred them, which is part of why recognized sex ratios keep narrowing. AuDHD in men is more often caught early on externalizing traits and then closed at an ADHD label, with the autism side never revisited. Most of this literature studies children, so a good evaluation treats it as context and works from your own history.

What does an evaluation cost?

Current rates are published on our pricing page. CEREVITY is 100% private-pay: no insurance is billed, no superbills are issued, and no claim is ever filed on your behalf. For adults weighing an evaluation precisely because of what a record might do later, that structure is usually the reason they chose it.

Why is this private-pay rather than billed to insurance?

Billing an insurer requires a billable diagnosis code, and that code enters a carrier's file, where it can resurface years later in underwriting, in licensing review, or in litigation. Paying privately produces no code, no claim, and no third-party record. It also means the evaluation runs to the length the clinical question needs, rather than the length a utilization reviewer will authorize.
