Symptoms of high-functioning autism (ASD) in adults often involve social communication challenges like literal thinking, difficulty reading cues, and awkward conversation, coupled with intense special interests, sensory sensitivities (lights, sounds), strict routines, and repetitive behaviors (stimming), leading to anxiety and feeling overwhelmed, though many learn masking strategies to fit in.
Individuals with HFA typically have normal to above-average intelligence and may excel in certain areas, such as academics or specific interests. However, they often struggle with social interactions, communication, and understanding social cues, which can impact their daily lives.
Females with high-functioning ASD are diagnosed even later in life as compared to males. These females initially present with behavioral, affective, and anxiety symptoms. In many instances, they have multiple previous diagnosis and do not show progress or improvement with several evidence-based interventions.
find it hard to communicate and interact with other people. find it hard to understand how other people think or feel. find things like bright lights or loud noises overwhelming, stressful or uncomfortable. get anxious or upset about unfamiliar situations and social events.
Level 1 autism: “Requiring support”
May appear to have decreased interest in social interactions. For example, a person who is able to speak in full sentences and engages in communication but whose to- and-fro conversation with others fails, and whose attempts to make friends are odd and typically unsuccessful.
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.
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.
Meltdowns are often the result of situations with high demand in one or a few of the following areas: Social situations (for example social anxiety or misunderstandings) Sensory overload (for example to much noise, light, itchy clothes) Experiencing changes and unpredictable things.
A recent study2 suggested that more than 70% of autistic children and adults had a special isolated skill in memory (52% of the sample), visuo‐spatial abilities (32%), calculation, drawing or music (about 17% for each area).
Top 10 Calming Strategies for Autism
Females tend to mask signs of autism
Females with autism learn or mimic socially acceptable behavior by watching television shows, movies and the people around them. They may copy the facial expressions of others to hide social communication challenges. Those efforts can cause mental exhaustion, stress and anxiety.
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.
This state of hyper-arousal can lead to autistic people experiencing meltdowns or shutdowns as a result of being completely overwhelmed. Several autistic people have talked of experiencing alexithymia a difficulty identifying, understanding and describing emotions).
Physical Symptoms:
Many individuals with HFA exhibit ritualistic eating behaviors. These can include eating foods in a specific order, requiring foods to be prepared or presented in a particular way, or using specific utensils. These rituals provide a sense of control and predictability, which can help reduce anxiety during meals.
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"
There is not just one cause of ASD. Many different factors have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
Some specific triggers for a meltdown in an Autistic person – child or adult – may be:
Examples of literal thinking in autism
Common colloquial phrases are sometimes taken literally by autistic individuals, who may misunderstand the meaning. For example, if someone says, “Break a leg” or “Hit the books,” a literal thinker might take it as actually breaking a leg or physically striking their books.
Many autistic people experience hypersensitivity to bright lights or certain light wavelengths (e.g., LED or fluorescent lights). Certain sounds, smells, textures and tastes can also be overwhelming. This can result in sensory avoidance – trying to get away from stimuli that most people can easily tune out.
Many autistic people are motivated to have friends, relationships and close family bonds, despite the clinical characterisation of autism as a condition negatively affecting social interaction. Many first-hand accounts of autistic people describe feelings of comfort and ease specifically with other autistic people.
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.
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.
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.
