What Is Autism Spectrum Disorder (ASD)?

Autism Spectrum Disorder (ASD), also known as Autism Spectrum Condition (ASC), is a lifelong neurodevelopmental condition that affects how a person perceives and interacts with the world. It influences social communication, behavior, and sensory processing. Autism is a spectrum, meaning experiences vary widely — no two autistic people are exactly the same.

According to the CDC, approximately 1 in 36 children in the United States is diagnosed with autism. Globally, autism affects an estimated 1–2% of the population. Many adults remain undiagnosed well into their thirties, forties, and beyond — particularly women and those who learned to "mask" their autistic traits.

Common Signs of Autism in Adults

Adults with autism often experience a distinct set of characteristics that can go unrecognized for years. Common signs include:

• Difficulty reading facial expressions, tone of voice, or social cues
• Preference for routine and distress when routines change unexpectedly
• Deep, highly focused interests in specific subjects or topics
• Sensory sensitivities — over- or under-sensitivity to sounds, light, texture, or smell
• Challenges with small talk or "neurotypical" social conventions
• Taking language very literally; difficulty understanding sarcasm or metaphor
• Feeling exhausted after social interactions (social fatigue or "autistic burnout")
• Strong sense of justice and honesty; discomfort with ambiguity

Early Signs of Autism in Children

Autism in children can often be identified early, sometimes as young as 18–24 months. Early recognition gives children access to support and interventions that can make a significant difference. Key signs in children include:

• Limited or no eye contact during interaction
• Delayed speech or language development (or loss of previously acquired words)
• Not responding to their name by 12 months
• Repetitive behaviors: hand-flapping, rocking, spinning objects
• Strong attachment to specific routines; intense distress at changes
• Unusual sensory responses: covering ears, avoiding certain textures or foods
• Difficulty playing imaginatively or engaging in cooperative play
• Focused, intense interests in specific objects or topics

Autism in Women and Girls: The Hidden Diagnosis

Research consistently shows that autism in women and girls is significantly underdiagnosed. This is largely due to "masking" — a coping mechanism where autistic individuals learn to imitate neurotypical social behaviors, often at great personal cost. Girls with autism are more likely to have strong verbal skills that can mask underlying social difficulties, and are often misdiagnosed with anxiety, depression, or borderline personality disorder before receiving a correct autism diagnosis.

Studies suggest that for every three autistic men diagnosed, only one autistic woman receives a diagnosis — despite prevalence rates being likely much more equal. If you are a woman who has always felt different, struggled socially while appearing to cope, or been told your concerns are anxiety-related, an autism screening may be a valuable first step.

Types of Autism: Understanding the Spectrum

Since the DSM-5 revision in 2013, the various subtypes of autism — including Asperger's Syndrome and PDD-NOS — were unified under the single diagnosis of Autism Spectrum Disorder (ASD). Severity is now described in levels based on the support required:

• ASD Level 1: Requires support — noticeable challenges in social communication, but manages many daily activities independently
• ASD Level 2: Requires substantial support — marked difficulties in social communication and flexible behavior
• ASD Level 3: Requires very substantial support — severe challenges impacting most daily functioning

What Happens After a Positive Autism Screening?

A positive result on our autism screening does not mean you or your child has autism. It means some of your responses are consistent with traits associated with autism spectrum conditions, and that seeking a professional opinion may be worthwhile. The next steps typically include:

• Speaking with your GP or family doctor about your concerns
• Requesting a referral to a clinical psychologist, psychiatrist, or developmental pediatrician
• Keeping a diary of observed traits or behaviors to share with the professional
• Exploring autism support communities and resources while waiting for assessment

A formal autism assessment typically involves a structured clinical interview, behavioral observation, and standardized psychological tests. It may take several sessions and may involve input from family members or teachers.

About Our Autism Screening Test

Our free autism test is a 20-question educational self-screening tool. It is inspired by validated instruments such as the AQ-10 (Autism Spectrum Quotient) and the M-CHAT (Modified Checklist for Autism in Toddlers), but uses entirely original question content and is not a replacement for these clinical tools.

The test covers five key domains associated with autism: Social Communication, Sensory Sensitivity, Routine and Flexibility, Behavioral Patterns, and Cognitive Style. Each domain is scored separately to give you a nuanced breakdown of your results.
