Acronym
What does ASD mean?
Acronym for autism spectrum disorder: the clinical English name for a neurodevelopmental diagnosis that Portuguese and Spanish usually call TEA.
Definition
ASD (autism spectrum disorder) is a neurodevelopmental diagnosis: persistent differences in social communication plus restricted or repetitive patterns of behavior, interests or sensory life. Spectrum here is not a single mild-to-severe score. It is the idea that the mix of traits and of support needed changes from person to person. DSM-5 (2013) and ICD-11 (in force at the WHO since 2022) gathered what DSM-IV had sliced into autistic disorder, Asperger’s, childhood disintegrative disorder and PDD-NOS.
Someone who already had an Asperger’s report stays on the spectrum; current manuals describe support levels (1, 2, 3), not a second disorder. Many people still use Asperger’s as identity or as shorthand for fluent speech without intellectual disability. In cardiology ASD is something else: atrial septal defect, a hole between the atria. The rest of the chart — development versus heart — splits the two acronyms.
Origin
English autism spectrum disorder, consolidated in DSM-5 (2013) from Lorna Wing’s spectrum idea (1980s). Portuguese and Spanish usually say TEA. Kanner described infantile autism in 1943; Asperger a profile with developed speech in 1944.
History
From clinic and school to adult reports, autistic networks and HR. ICD-11 at the WHO (code 6A02) aligned with the single spectrum; some countries still bill under ICD-10 (F84). Asperger’s stayed in personal use and in the history of the manuals.
How it emerged
Several clinical names described the same territory. A short code was needed that a report, a family and an autistic person could all repeat.
Usage examples
The report says ASD, support level 1.
TEA and ASD are the same diagnosis in different languages.
On the echocardiogram, ASD was the septal hole; at the developmental clinic, the spectrum.

Questions
What does ASD mean?
Autism spectrum disorder: a neurodevelopmental diagnosis with differences in social communication and restricted or repetitive patterns, in combinations that change from person to person. In Portuguese and Spanish the usual letters are TEA.
Are TEA and ASD the same?
Yes. ASD is the English acronym; TEA is the usual form in Portuguese and Spanish (transtorno/trastorno do/del espectro autista). Same field; different language on the letters.
Is Asperger’s still a diagnosis?
In current manuals, Asperger’s is no longer a separate category. Since DSM-5 (2013) and ICD-11, that profile sits inside ASD, often with lower support needs around language. Many people still use Asperger’s as an identity name; the clinic writes spectrum and a support level.
What is the ICD code for ASD?
ICD-11, in force at the WHO since 2022, uses a single code: 6A02, autism spectrum disorder. ICD-10 still lists separate F84 codes (childhood autism, Asperger’s, PDD-NOS). Some health systems have not finished the switch.
Does ASD also mean a heart condition?
In cardiology, ASD means atrial septal defect: a hole in the wall between the atria, present at birth. In developmental pediatrics and mental health, the same three letters mean autism spectrum disorder. The specialty and the rest of the sentence decide.
Does spectrum mean mild autism?
Spectrum describes the range of presentations and of support, not one severity grade. DSM-5 levels 1, 2 and 3 name how much support is needed now, and that can change. Level 1 does not mean the inner life is easy.
