Do vaccines cause autism?

No. This claim originated from a discredited and retracted study, and it has been thoroughly disproven by numerous large, high-quality studies worldwide. Vaccines do not cause autism, and delaying them puts children at risk of serious preventable diseases.

Can adults be diagnosed with autism?

Yes. Many autistic people, especially women and those without intellectual disability, are not identified until adolescence or adulthood. An adult diagnosis can provide valuable self-understanding and access to support, and it is increasingly common.

Is there a cure for autism?

Autism is a lifelong neurodevelopmental difference, not a disease, so it is not something to be cured. The goal of support is to help autistic people communicate, learn, and live in ways that work for them, and to address any co-occurring conditions that cause distress.

NeurologicalICD-10: F84.0Estimated to affect about 1 in 36 children in recent surveillance data

Autism Spectrum Disorder

Also known as: ASD, Autism, Autistic spectrum disorder

Autism spectrum disorder (ASD) is a lifelong neurodevelopmental condition that affects how a person communicates, interacts socially, and experiences the world. Because it is a 'spectrum,' the way it presents varies enormously from one individual to another — from people who need substantial daily support to those who live fully independently. Common features include differences in social communication and restricted or repetitive interests and behaviors, often alongside distinctive sensory sensitivities. Autism is not an illness to be cured but a difference in neurological development; early support and understanding help autistic people thrive.

Symptoms

Differences in social communication and reciprocal interaction

Difficulty interpreting body language, tone, or facial expressions

Limited or atypical eye contact

Strong, focused interests in specific topics

Repetitive movements or behaviors (such as rocking or hand-flapping)

Strong preference for routine and difficulty with change

Heightened or reduced sensitivity to sounds, lights, textures, or smells

Delayed language development in some individuals

Causes

Complex combination of genetic factors (autism is highly heritable)
Differences in early brain development
Prenatal and environmental factors that interact with genetic predisposition
No single cause; vaccines do not cause autism

Risk Factors

Having a sibling or family member with autism
Certain genetic conditions (such as fragile X syndrome)
Advanced parental age
Very premature birth or low birth weight
Male sex (diagnosed more often, though autism in girls is frequently underrecognized)

Diagnosis

Developmental screening during routine childhood check-ups
Comprehensive evaluation by a multidisciplinary team
Standardized observational and interview tools (such as the ADOS and ADI-R)
Assessment of communication, behavior, and developmental history
Evaluation for co-occurring conditions (ADHD, anxiety, intellectual disability)

Treatment

Individualized support rather than a 'cure'
Speech and language therapy
Occupational therapy, including for sensory needs
Behavioral and developmental supports tailored to the person and family
Educational accommodations and social-skills support
Treatment of co-occurring conditions such as anxiety, ADHD, or sleep problems

Prevention

Autism cannot be prevented and is a natural form of neurological variation
Early identification and support improve developmental and quality-of-life outcomes
Good prenatal care supports healthy development overall

When to See a Doctor

Your child is not meeting communication or social milestones
Loss of previously acquired speech or social skills
Not responding to their name by 12 months or not pointing or showing objects by 18 months
Strong distress with changes in routine or intense sensory reactions affecting daily life
You or your child are seeking an autism evaluation at any age
