While "high-functioning autism" is not an official diagnosis in the DSM-5, it is an informal term often used to describe individuals with Autism Spectrum Disorder (ASD) who have average or above-average intelligence and lower support needs (Level 1 ASD).
If you have low support needs (high-functioning autism), you may have symptoms such as:
What are the symptoms of autism? The two core autism symptoms are: Challenges with social communication and interaction skills and. Restricted and repetitive behaviors.
Children with high functioning autism may struggle with understanding social cues, nonverbal communication, and the nuances of social interactions. They may have difficulty initiating and maintaining conversations, understanding others' perspectives, and interpreting facial expressions and body language.
Symptoms of High-Functioning Autism
Difficulty with Social Interaction: Individuals with high-functioning autism may struggle to understand social norms, make eye contact, initiate or maintain conversations, and interpret nonverbal cues such as facial expressions or body language.
One common expression of anger in high-functioning autism is intense emotional outbursts such as tantrums, verbal aggression, and even physical aggression. These episodes can include shouting, name-calling, hitting, slapping, or destroying objects.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
While the term Asperger's Syndrome no longer formally exists in the diagnosis and insurance world, it is still a common term used to refer to an individual with high-functioning autism.
Individuals with high functioning autism often struggle to interpret non-verbal cues, such as facial expressions, body language, and tone of voice. These cues play a significant role in conveying emotions, intentions, and social nuances.
Main signs of autism
finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to. finding it hard to say how you feel. taking things very literally – for example, you may not understand sarcasm or phrases like "break a leg"
Several genes seem to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be related to a genetic condition, such as Rett syndrome or fragile X syndrome. For other children, genetic changes, also known as mutations, may raise the risk of autism spectrum disorder.
Seven key signs of autism spectrum disorder (ASD) often involve challenges with social communication (like avoiding eye contact, not responding to names), restricted/repetitive behaviors (like repetitive movements or strict routines), sensory sensitivities (unusual reactions to sounds, lights, textures), and difficulties with emotional understanding or verbal expression, though signs vary greatly and appear differently across ages. Key indicators include limited gestures, delayed speech, intense focus on specific objects, difficulty with pretend play, and strong distress when routines change.
How to tell if someone is high-functioning autistic? Look for difficulty with eye contact, social cues, sensory sensitivities, and intense interests, combined with strong verbal skills. Unlike severe symptoms in other developmental disorders, these signs are often subtle.
Characteristics of High-Functioning Autism
Autistic strengths
Savant syndrome is a rare condition in which persons with various developmental disorders, including autistic disorder, have an amazing ability and talent. The condition can be congenital (genetic or inborn), or can be acquired later in childhood, or even in adults.
Chinning is a form of repetitive self-stimulatory behavior (stimming) that you may notice in children or adults with autism. It involves pressing, rubbing, or holding the chin against objects, surfaces, or even hands to gain sensory input or comfort.
The phrase “high-functioning” doesn't have a clear definition. Dr. Wong prefers sticking with the medical terminology because it's defined in the DSM-5. “I try to educate parents so that they use the term 'level one autism' instead,” she says.
Additionally, inherited genetic variations contribute greatly. Research shows that both mothers and fathers can carry autism-related gene variants. Some of these are common variants that increase the risk of autism, while others are rare mutations causing more severe effects.

While the exact reasons are not yet clear, changes in how the disorder is defined, increases in screening, and more awareness certainly contribute to this increase. If you have any concerns about your child's development, speak to a healthcare professional about diagnostic tests.
Children with autism may exhibit rigidity, inflexibility and certain types of repetitive behavior such as: Insistence on following a specific routine. Having difficulty accepting changes in the schedule. A strong preoccupation with a particular interest.
In general, people who have an active lifestyle are much more emotionally resilient and focused. There also seems to be some evidence that physical exercise helps people with depression and ADHD, which are commonly co-occurring conditions with autism.
There's no single "hardest" age for autism; challenges shift across developmental stages, with preschool (2-5) often tough due to noticeable differences in social/language skills, elementary (6-10) marked by growing academic/social demands, and adolescence (11-17) frequently being overwhelming due to complex social pressures, puberty, and identity formation, say Bluebell ABA Therapy and Blossom ABA Therapy. While early childhood (ages 3-6) sees initial progress for many, this often stalls around age six, a critical turning point where increased support is crucial, according to research, notes The Transmitter.
