Study Identifies Four Biologically Distinct Autism Subtypes
Subtypes have unique genetic and developmental patterns
|
By Peter Clark (Senior Editor, Autism Info Center) Tuesday 29th July 2025 |
A study has identified four distinct biological subtypes of autism, offering a new path for personalised diagnosis and care.
Analysing data from over 5,000 children, researchers used a person-centred computational model to group individuals based on shared traits.
The subtypes identified are: Social and Behavioural Challenges (core autism features, often with ADHD/anxiety, typical development); Mixed ASD with Developmental Delay (delayed milestones, varied social/repetitive behaviours); Moderate Challenges (less pronounced autism traits, typical development); and Broadly Affected (most severe symptoms, significant delays, psychiatric conditions).
Each subtype is linked to unique genetic markers and developmental patterns, providing deeper insight into autism's complex biology.

Have you seen our books about Autism and Neurodiversity?
Written by an autistic author, this book explains what autism is, what it isn't, and how to support autistic people with kindness and consideration. It aims to help the friends, family and carers of autistic people, as well the general public, educators, healthcare providers, employers, authorities, and anyone else who might interact with autistic people. It clearly and concisely shows them what autism can 'look like', how to recognise it, how to sensitively offer support, and how to advocate for greater awareness, acceptance and inclusion in society.
The Autism Manifesto provides a vital 'lived perspective' on autism and advocates for greater understanding, inclusion, and integration for autistic people in society. The manifesto challenges outdated views of autism as a deficit or something to be 'cured', instead presenting it as a natural human variation, and highlights the fact that different ways of thinking only serve to enrich society. Its core lies in the 10 Pillars of Inclusion, which offer direct, practical steps that everyone can take to improve the lives of autistic people in every walk of life, at home, at work, at school, in the community, in government, and in the authorities and legal systems.
This is a book for autistic people, by an autistic writer. It helps you understand and embrace your autism and focus on all its positive sides (and all your strengths that come with it), as well as how to calm yourself in troubled times, and how to live a full life that's even happier, more fulfilling, and more meaningful, as part of your community. There are hundreds of practical ideas and advice for going out and enjoying life, meeting new people, making new friends, and maintaining existing relationships. It really is a guide to becoming the very best version of yourself!
DJ Merryweather is autistic, and shares his life experiences of autism - always trying to fit in, masking his differences at every turn - and how it led to his ultimate burnout, after which he began dismantling his autistic masking habits, one by one. The book explains why you're masking, how bad it can make you feel, and why you probably feel like you're stuck with it - from social rules and situations to 'faking' emotions and learning to 'perform' feelings in socially expected ways. But most of all, it's an inspiring message about the value of unmasking your true self and living a happier, more fulfilling life.
