Portrait of Dr Alison Lennox

A dedicated practice focusing on adult autism assessment. For ages 17+, from across the UK. Specialising in late-identified autism, AuDHD, and complex, co-occurring conditions. Built on accuracy and clarity. Welcoming adults seeking an assessment for themselves, and clinicians who want to refer to someone they trust.

Your life works, broadly, but at a high cost. You've succeeded by working harder than others, then privately recovering. The strain is starting to show.

You are anxious you might have spent a lifetime masking. Someone close has raised the possibility, but you've been told you "don't look autistic."

You've gathered multiple mental health labels, or maybe ADHD, but something isn't adding up.

A complex physical picture: hypermobility, EDS, PoTS, ME/CFS, chronic pain. You've seen many specialists but need to join the dots.

Your psychiatrist or therapist suspects autism. Together you want your care to reflect who you really are.

An earlier assessment didn't feel like you. You'd like to be considered for a second opinion.

You were diagnosed as a child, and the conversation stopped there. You'd like to understand more.

Who finds their way to me

Standalone autism screening

An indicative, non-diagnostic screening that explores autistic traits.

Combined autism & ADHD (AuDHD) assessment

A single integrated assessment covering both autism and ADHD.

Autism diagnosis review

For adults diagnosed in childhood who want their diagnosis contextualised today.

Second opinion assessment

For people who've had a previous assessment and want it reviewed or reconsidered.

How I can help

Clinical practice
I'm a private psychiatrist who has worked exclusively in adult neurodevelopmental psychiatry since 2019. I was formerly Clinical Lead for an NHS adult autism diagnostic service and also worked in an ADHD service. I'm on the GMC specialist register with liaison psychiatry endorsement, trained at the intersection of physical and mental health. As a psychiatrist, I'm trained to spot where autism overlaps with conditions like eating disorders, bipolar disorder, or ADHD, giving you real diagnostic clarity.
Leadership and training
I sit on the Royal College of Psychiatrists' Neurodevelopmental Psychiatry SIG, and co-authored its patient leaflet on autism and mental health. I've also lectured on diagnosis and risk on the National Autism Training Programme for Psychiatrists. I have mentored consultant colleagues nationally.
Education
I hold an MA from the University of Cambridge and an MBBS from University College London. I was an Oxford University Medical Education Fellow, Honorary Teaching Fellow in the Department of Psychiatry, and am a Fellow of the Higher Education Academy.
Lived experience
I'm a late-diagnosed autistic psychiatrist with synaesthesia. I share this because I'm commonly asked, and it informs how I work, bringing both clinical expertise and personal understanding to every assessment I design.
