What we know about autism, and how we know it.

What it is, and what it isn’t

Autism is a way of processing the world that is present from birth and lasts a lifetime. It isn’t an illness, it has no cure, and it isn’t caused by vaccines, by parenting, or by anything anyone did. It is largely hereditary.

Autistic people share three traits, each in their own way: social interaction and communication work differently; predictability, routines and intense interests organize the world; and the senses are experienced more intensely, less intensely, or both at once.

People say “spectrum” because each person has their own profile. It isn’t a line from “mild” to “severe”. The same person may need a lot of support for some things and none for others, and that changes with the day, the place and the people around them. That’s why we talk about support needs, not “functioning levels”.

About one in a hundred people worldwide is autistic, according to the broadest review available. In the United States, where surveillance is most intense, the figure reaches one in thirty-one among eight-year-olds. Chile has no national figure.

What it’s like

The senses. A fluorescent light, a clothing tag, the sound of a blender or the smell of food can be unbearable. At other times the body doesn’t register hunger, thirst, cold or pain until it’s too much. About half of autistic people find it hard to identify and name what they feel; it’s called alexithymia, and it explains why “how do you feel?” is, for many, a genuinely hard question.

Communication. Many autistic people take words literally and prefer to be spoken to directly. Processing what was said takes time; repeating the question too soon restarts the process. Not making eye contact doesn’t mean not listening: many people find it hard to listen and look at the same time. And some people speak well and at times can’t speak at all, from exhaustion or overload. It isn’t a choice.

Predictability. An unexpected change costs energy, even a small one. Routines aren’t rigidity: they’re what makes the day manageable. Warning in advance, showing what comes next, and explaining the reason for a change make an enormous difference.

Interests. Trains, maps, a character, numbers, animals. Intense interests aren’t a problem to be reduced. They regulate, they bring joy, and they are one of the best ways to connect with an autistic person: following their interest and sharing it improves communication, and that is the best-supported finding in research with families.

Energy. Many autistic people describe a limited amount of daily energy. Socializing, noise, change and pretending everything is fine use it up; rest, solitude and interests restore it. When what’s spent exceeds what’s recovered for weeks, the exhaustion we describe below sets in.

The double empathy problem

For decades, autistic people were described as lacking empathy. The research of the last fifteen years says otherwise: when an autistic and a non-autistic person don’t understand each other, the difficulty belongs to both. Between autistic people, communication flows better; between non-autistic people, too. The problem appears at the crossing.

This changes what needs to be built. The point isn’t to teach autistic people to seem non-autistic; it’s to translate in both directions. That’s why Autis’s translator explains to the person what they’re being told, and to the other side how to read what the person said, without changing their voice.

Across a lifetime

Childhood. Diagnosis usually comes late: in Chile, families notice the first signs at around two and a half years, and the diagnosis arrives near five. What the evidence supports at that stage is clear and modest at the same time: follow the child’s interest, comment and wait for their turn, use pictures and visual routines, and offer augmentative communication early. Using symbols or a communication board doesn’t hold back speech; it’s one of the strongest findings in the field.

Adolescence. Control starts passing to the person: what they share, with whom, what they decide. It’s the stage where masking weighs most, and where puberty, sexuality and boundaries need to be talked about in concrete language.

Adulthood. Work, independent living, relationships, health. In the United Kingdom, where it’s measured, only three in ten autistic adults are employed. Chile has no figure. Most services and apps are still built for children; autistic adults are left out.

Late diagnosis. More and more people are diagnosed as adults, many of them women, because the way autism was described for decades left out those who learned to hide it. A late diagnosis often brings relief and grief at once: understanding a whole life all of a sudden. Autis supports that process with honest information about what self-knowledge questionnaires do and don’t measure, and it never diagnoses.

High support needs. Some autistic people don’t speak, have an intellectual disability, or need support around the clock. Research includes them little and apps almost not at all. For them, augmentative communication is the main means, not an add-on, and the people who care for them need nothing to be lost between one shift and the next.

Meltdown and shutdown

When the load becomes too much, many autistic people have one of two reactions. A meltdown: the load goes outward, with crying, shouting, hard movements or a need to escape. A shutdown: the load goes inward, the person goes still and silent, and speaking or moving becomes impossible.

Neither is a choice, and neither is a tantrum or manipulation. A meltdown usually lasts minutes; a shutdown can last hours.

What helps: less light, less noise, fewer people; few words or none; space and time; nobody demanding speech, eye contact or explanations. What doesn’t: restraining, shouting, telling them to “calm down”, punishing afterwards. Autistic people have worse experiences with police and emergency services precisely because a crisis gets mistaken for aggression or intoxication. That’s why Autis has a crisis card: so that whoever is nearby knows what to do and what not to do.

Masking and burnout

Masking means hiding or changing autistic traits to fit in: forcing eye contact, rehearsing conversations, copying others, putting up with a noise without saying anything, keeping still when the body asks to move. Many people do it from childhood without realizing, and it’s more common in women and in people diagnosed as adults.

It has a measured cost: more exhaustion, anxiety and depression, and a higher risk of thinking about self-harm. That doesn’t make masking wrong; sometimes it’s what gets you through a moment. It means it’s worth choosing where, and that no app should train it.

Autistic burnout is what happens when what’s spent exceeds what’s recovered for months: exhaustion that sleep doesn’t fix, loss of skills you had (speaking, getting organized, cooking) and less tolerance for stimulation. Autistic people described it before research did. There are no treatment studies yet; what helps, according to those who’ve been through it, is lowering demands, reducing stimulation and time alone.

Mental health and risk

Autistic people have more anxiety, depression, sleep problems and physical ailments than the general population, and much of that is explained by living in a world not built for them. They also have a risk of suicide several times higher, highest in adults without intellectual disability and in women. In one study of autistic adults at a diagnostic clinic, two in three had thought about ending their life.

This isn’t said to frighten. It’s said because asking directly about suicide doesn’t increase the risk, and because the supports that work exist: a safety plan written when calm, trusted people you can ask for help without speaking, and professionals. In Chile, the Ministry of Health’s *4141 line answers free, 24 hours a day, and 131 is the emergency number. Outside Chile, the app shows your country’s line. If you are in danger right now, call the emergency number where you are.

Adapted cognitive behavioural therapy has evidence for anxiety, mostly in children and with a therapist. Apps, Autis included, are not treatment. They can accompany, record, connect and alert. They can’t do more than that, and it matters to say so.

Neurodiversity, language, and what we don’t do

Neurodiversity is the idea that differences in how brains work are part of human variation, and that the goal of support is the life the person wants, not resembling everyone else. It doesn’t deny difficulties or support needs: it changes where support points.

Language matters. Most of the adult autistic community prefers “autistic person” to “person with autism”, rejects “high” and “low functioning”, and rejects the words of tragedy: suffer, afflicted, burden. We use “autistic person” by default, and each person chooses how they want to be spoken about.

What Autis doesn’t do, on principle: it doesn’t train eye contact, doesn’t try to suppress stimming, doesn’t reward “good behaviour”, doesn’t use token economies or normalizing behavioural therapies, doesn’t diagnose, doesn’t sell data and shows no advertising. When a behaviour puts someone at physical risk, it refers to a professional.

What you’ll hear, and what is known

Promises of cures circulate. Some are merely false; others kill. This is what the evidence says.

• “Vaccines cause autism.” False. A study of more than 650,000 children in Denmark found no link, including among siblings of autistic children.
• “Chlorine dioxide or MMS cures autism.” False and dangerous. The US drug regulator equates it to drinking bleach: it causes vomiting, severe diarrhea, very low blood pressure and liver damage.
• “Chelation removes the metals that cause autism.” False. No trial shows any benefit, and it has caused deaths.
• “A special diet cures it.” There is no evidence that diet changes autism. Changing it without a professional can cause deficiencies, especially in children with selective eating.
• “If you don’t intervene before age five, the window closes.” There is no evidence of a closing window. Support helps at any age; guilt doesn’t.
• “It’s caused by parenting.” False. Autism is largely hereditary.
• “Autistic people don’t feel empathy.” False. They feel, sometimes with an intensity that overwhelms. What’s hard is reading each other across different ways of processing, and that goes both ways.

In Chile

Law 21.545, from 2023, recognizes the rights of autistic people in health, education and social life, and states that a diagnosis is enough to access its benefits, with no need to register in the National Disability Registry. Implementation is slow: autism isn’t covered by the GES health guarantees, and in the public system the median wait for a new specialist appointment is over two hundred days.

What is known in numbers: the 2022 national disability survey estimated 44,594 autistic adults, half of them without recognized disability. The school system has more than 55,000 autistic students, 51,546 of them in the School Integration Programme. The only prevalence estimate comes from two districts of Santiago and can’t be generalized. There is no registry, no figure for adults in employment, no autism-specific waiting list. One of the things Autis wants to contribute is measurement.

For families: the School Integration Programme (PIE) exists in public and subsidized schools, and schools are required to have protocols. Senadis and community organizations publish plain-language guides to the law. They’re listed below.

How Autis is built from this

Every feature of Autis comes from what is on this page. Today’s energy exists because exhaustion and burnout are real and nobody records them. Crisis mode and the card exist because a crisis gets misread. “I can’t talk right now” exists because some people speak and at times can’t. The Manual exists because explaining the same thing to every doctor, teacher and boss is exhausting. The translator exists because of double empathy. And Nía speaks briefly and literally because that is what autistic people who use AI ask for.

What we don’t promise also comes from here. We don’t predict crises: no study has managed it outside a hospital. We don’t treat anxiety. We don’t say the app improves outcomes until we measure it with a Chilean university, and that is part of the plan.
