Lionel Messi and the Autism Rumor: How a Brazilian Fake News Story Became Football's Longest Hoax
For more than a decade, a false claim has followed Lionel Messi across the internet: that the Argentina captain was diagnosed with autism or Asperger's syndrome as a child. The story has never been confirmed by Messi, his family, his doctors or any credible medical record. It is one of the most persistent fake news stories in modern football — and it resurfaces every time Messi dominates a World Cup.
Quick answer: Messi has never been diagnosed with autism or Asperger's. The rumor began with a 2013 blog post by Brazilian journalist Roberto Amado, was amplified by Romário, and was denied by Messi's father and childhood doctor. Messi's documented childhood condition was growth hormone deficiency (GHD) — a completely separate medical issue.
What People Claim About Messi and Autism
The viral narrative usually includes some or all of the following:
| Claim | Status |
|---|---|
| Messi was diagnosed with Asperger's at age 8 in Rosario | False — no diagnosis on record |
| His family hid the diagnosis to protect his career | Unverified speculation |
| His quiet personality, focus and dribbling patterns prove autism | Anecdotal — not medical evidence |
| Romário confirmed the story publicly | Partially true — he repeated the rumor, not a diagnosis |
| Messi has "savant syndrome" like the film Rain Man | False — fictional comparison |
None of these claims meet basic fact-checking standards. Messi himself has never discussed an autism diagnosis in any interview, autobiography or authorised biography.
Where the Story Started: August 2013, Brazil
The rumor is widely described as a "genuine Brazilian fake news" story. Its documented origin is a blog post published on 27 August 2013 by journalist Roberto Amado on his personal site Poucas Palavras ("Few Words").
Roberto Amado's original article
Amado — nephew of the celebrated Brazilian writer Jorge Amado — published a piece titled "Como o autismo de Messi ajudou-o a ser gênio" ("How Messi's autism helped him become a genius"). In it, he claimed Messi had been diagnosed with Asperger's syndrome at age eight while still living in Rosario, Argentina.
The article did not cite medical records, family sources or clinical interviews. Instead, it linked Messi's reserved behaviour in front of cameras, his focus during matches and certain on-pitch habits to traits sometimes associated with autism spectrum conditions.
Amado also drew parallels between Messi and Raymond Babbitt, the autistic savant played by Dustin Hoffman in the 1988 film Rain Man, and referenced Savant syndrome — a rare condition in which a person shows extraordinary ability in a narrow field.
A related piece appeared around the same period on the Brazilian site Diário do Centro do Mundo ("Como o autismo ajudou Messi a se tornar o melhor do mundo"), reinforcing the same unverified narrative.
Amado later admitted he had no scientific basis
In a follow-up interview with <strong>Goal.com</strong> ("Lionel Messi and the misunderstanding about autism"), Amado conceded that his claim was behavioural speculation, not medical reporting:
- He said he had no scientific basis for the conclusion ("No tengo ninguna base científica").
- He referenced a medical report he had never actually published or made public.
- He described the article as based on "distant behavioural analysis" and his childhood experience around neurodevelopmental patients — not on Messi's clinical records.
Amado told Goal his intention was to show that autistic people "can relate, live normally and be very productive" — but the piece was widely read as a factual diagnosis. That gap between intent and impact is exactly how sports fake news spreads.
Key point: At the time, Asperger's syndrome was still classified separately from autism in many countries. In 2013, the DSM-5 merged Asperger's into Autism Spectrum Disorder (ASD). The rumor predates modern clinical language — but the underlying claim remains unproven either way.
How Romário Amplified the Hoax
The blog post might have faded into obscurity — but on 8 September 2013, Brazilian legend Romário posted on social media:
"Did you know that Messi has Asperger Syndrome? It's a mild form of autism, which gave him the gift of focus and concentration above all else."
Romário's tweet received hundreds of likes and was widely shared in Brazil and Spain. He followed up by comparing Messi to Isaac Newton and Albert Einstein, suggesting they shared similar traits linked to Asperger's.
Romário was not reporting a verified fact. He was repeating Amado's speculation — and his celebrity status gave the story enormous reach. English-language outlets including <strong>Africa Top Sports</strong> covered the tweet within hours, spreading the claim to international audiences. Former France international Christopher Dugarry later shared similar false information, extending the rumor into European media.
Romário also appeared in a widely shared <strong>Oh My Goal</strong> video discussing the article — one of the main vectors that kept the story alive on YouTube for years. In a later clarification, he said he was not a doctor and was only sharing information circulating in Brazil.
When the story reached Jorge Messi, Lionel's father, the response was unequivocal. Jorge categorically denied any autism-related diagnosis and said the family was considering legal action against those spreading the claim.
Romário later doubled down, criticising press coverage and saying he was not worried about being sued. No lawsuit appears to have been filed publicly — but the family's denial stands as the strongest on-record rebuttal from Messi's inner circle.
What Messi's Real Childhood Diagnosis Was
While the autism story is false, Messi did face a serious medical challenge as a boy — and confusing the two conditions has fuelled the rumor for years.
| Condition | Messi? | Details |
|---|---|---|
| Growth hormone deficiency (GHD) | Yes — confirmed | Diagnosed in childhood; treated with hormone injections in Argentina and at Barcelona |
| Autism / Asperger's | No — denied | No diagnosis from Messi, family or doctors |
Messi was famously small for his age in Rosario — earning the nickname "La Pulga" ("The Flea"). At age 11, he was diagnosed with growth hormone deficiency, a condition in which the body does not produce enough growth hormone for normal development.
He was treated by endocrinologist Dr Diego Schwarzstein in Rosario before FC Barcelona agreed to fund his hormone therapy and move his family to Spain.
When journalists contacted Dr Schwarzstein about the autism rumor, his response was blunt:
"Leo has never been diagnosed with Asperger's, or any other form of autism. That is nonsense." ("Isso é bobagem.")
The same quote appears in English-language fact-checks including <strong>I AM</strong> and <strong>Sporthiatus</strong>, both of which stress that GHD and autism are completely separate conditions.
GHD and autism are medically unrelated. Growth hormone deficiency affects physical development; autism spectrum conditions affect social communication and behaviour. Conflating them — or treating Messi's shyness as clinical evidence — is a category error that English-language outlets <strong>The18</strong> and <strong>Sports Digest</strong> have both flagged.
Expert and Biographer Responses
Beyond Messi's family doctor, multiple credible voices have dismissed the claim:
Guillem Balague — authorised biographer
Spanish journalist Guillem Balague, author of the authorised biography Messi (based on interviews with Messi, his family and Pep Guardiola), was asked directly about the autism rumor. His answer: the story was "rubbish" ("un lixo") — information to be discarded entirely.
In a <strong>Bleacher Report</strong> interview about writing the book, Balague said separating "myths and legends" from fact was one of the hardest parts of the project — and that many widely shared Messi stories were "apocryphal or downright false." His authorised biography documents Messi's growth hormone treatment and family struggles; it contains no autism diagnosis.
In a December 2013 <strong>The42</strong> interview, Balague described how Messi's childhood — leaving Argentina at 12, hormone injections, a complex relationship with his father — shaped his personality, without any reference to autism or Asperger's.
Dr Estevão Vadasz — autism specialist (USP, Brazil)
Psychiatrist Estevão Vadasz, coordinator of the Autism Spectrum Disorders Programme at the University of São Paulo's Institute of Psychiatry, told Brazilian media that it was unlikely Messi is on the autism spectrum.
He noted that many autistic individuals show reduced motor coordination and difficulty with team sports — the opposite of Messi's profile as one of history's most coordinated team players.
Fact-checking consensus
Major Brazilian outlets including <strong>Revista Fórum</strong>, <strong>Gazeta de São Paulo</strong> and UOL have classified the claim as fake news. English-language references include:

Why the Rumor Keeps Coming Back
The Messi autism story is not a one-time event. It follows a predictable cycle:
- 2013 — Amado blog post → Romário tweet → Jorge Messi denial
- 2018–2022 — Social media compilations of Messi "stimming" or avoiding eye contact during matches
- Qatar 2022 — Mass resurgence on Twitter and TikTok after Argentina's World Cup win
- 2026 — Renewed interest as Messi breaks the all-time World Cup goals record at USA 2026
The "autism compilation" meme
On TikTok, YouTube and Twitter/X, users post edited videos of Messi:
- Looking away from interviewers
- Repeating dribbling patterns
- Celebrating in muted ways
- Focusing intensely before free kicks
These clips are presented as "proof" of autism — but behavioural observation without clinical assessment is not diagnosis. Many elite athletes display intense focus, ritualised pre-match routines and discomfort with media attention for reasons unrelated to neurodevelopment.
Know Your Meme traces the modern meme cycle to mid-2022, when compilations titled "Messi Is Autistic" went viral alongside Argentina's tournament run. The entry documents the original June 2013 Diário do Centro do Mundo article, Romário's September tweet, and the 2022 Twitter/TikTok explosion — citing the 2013 Brazilian origin as the root of every subsequent cycle.
World Cup 2026: Why It Matters Now
At USA, Mexico and Canada 2026, Messi has surpassed Miroslav Klose to become the all-time leading World Cup goalscorer — a record that has put him back at the centre of global attention. Whenever Messi breaks a record or leads Argentina deep into a tournament, search interest in his personal life spikes — and old hoaxes resurface alongside legitimate coverage.
Spreading unverified medical claims about a living person:
- Misleads fans searching for accurate information
- Stigmatises autism by treating it as a curiosity or explanation for genius
- Ignores the documented denial from Messi's family and doctors
Responsible sports journalism treats the autism claim as debunked unless Messi or a licensed clinician confirms otherwise — which has not happened in over 13 years.
