Understanding autism in adults
Autism is a lifelong difference in how people communicate, connect, and experience the world. Many autistic adults were never identified as children — and screening questionnaires can be a helpful first step toward understanding yourself.
This is educational information, not a diagnosis. You can take the free, confidential screening.
Take the screeningWhat autism can look like in adulthood
Autistic adults often describe finding social cues harder to read, feeling drained after socialising, having strong focused interests, preferring predictable routines, and being more sensitive to sounds, lights, or textures.
Autism is dimensional: traits vary widely from person to person, and having some of these experiences does not, on its own, mean a person is autistic.
Why many adults are identified late
Public and clinical understanding of autism has changed a great deal over the past two decades. Adults who learned to adapt or mask their differences were frequently missed by criteria built around how autism looks in children.
As recognition has grown, more adults are seeking assessment for the first time.
Sex and gender differences in presentation
Research suggests that women and gender-diverse adults often present differently and may use strategies such as camouflaging that hide autistic traits, contributing to later or missed diagnosis (Green et al., 2019; Lai et al., 2016).
This is one reason our screening includes items designed to be sensitive to these presentations (Anunciacao, Murray & Marques, 2026).
What a screening questionnaire can — and can’t — tell you
A screening tool describes the relative frequency of certain experiences. It is not a diagnostic test and cannot confirm or rule out autism.
If your results resonate with you, the useful next step is a conversation with a qualified professional who can carry out a full assessment.
