Autism symptoms
Autism is not an illness. It is a different way of processing sensory input, language and social signals. The traits below describe how that can show up — not what is "missing". No one shows all of them, and no list replaces a proper assessment.
Social communication
Unspoken rules
Small talk, irony and hints do not decode automatically. They are worked out consciously — which costs attention and energy.
Eye contact
Direct eye contact can be uncomfortable to overwhelming. Looking away is not disinterest; it often means listening better.
Direct language
Literal understanding and honest, direct communication. Frequently misread as blunt, when it is simply clear.
Masking
Social behaviour is observed and deliberately imitated so as not to stand out. It works externally and produces exhaustion and loss of identity internally.
Sensory input, routines and interests
Sensory sensitivity
Sound, light, smell or fabric on skin can be physically unpleasant to painful — not "fussy", just processed differently.
Special interests
Deep, intense interests that allow enormous focus and joy. A strength, not a quirk.
Routines
Predictability creates safety. Unannounced change produces genuine stress — not stubbornness.
Stimming
Repetitive movements such as rocking or hand movements regulate the nervous system. Suppressing them helps no one.
Overload and meltdown
When input saturates, withdrawal (shutdown) or a meltdown follows. This is an overload response, not a loss of temper.
Exhaustion after socialising
One social evening can require days of recovery — the bill for hours of live social translation.
Note: these traits do not replace an assessment. An autism diagnosis is made by a qualified clinician on the basis of developmental history and detailed evaluation.

Are autism traits the same for everyone?
No. Autism is a spectrum: the traits and their intensity vary enormously from person to person. Two autistic people may at first glance have very little in common — which is exactly why we speak of a spectrum rather than a single profile.
Why is autism so often missed in women?
Many autistic women and girls compensate heavily: they observe social behaviour and imitate it. This masking hides the traits from everyone around them and costs an enormous amount of energy internally. It is a major reason diagnosis so often arrives in adulthood.
What is autistic overload?
A state in which sensory processing saturates — from noise, light, social demand, or all of it at once. The body responds with withdrawal, shutdown or a meltdown. It is not anger and not a tantrum: it is a nervous system past its limit.
Should these be called "symptoms"?
Many autistic people reject the word: autism is not an illness but a different way of processing information. People search for "symptoms", but the more accurate word is traits. What is often distressing is not being autistic — it is an environment that leaves no room for it.
