Many people have heard of autism, but there is still a lot of confusion about what it actually means.
Some people think autism only affects children. Others picture a very specific set of behaviours and assume that if someone does not fit that picture, they cannot be autistic. Many adults tell us they never considered autism as a possibility because they had friends, held a job, went to university, or appeared to cope well from the outside.
The reality is that autism can look very different from one person to another.
At The Hummingbird Centre, we meet children, teenagers, and adults who have spent years feeling different without fully understanding why. Some struggle with social situations and communication. Others feel overwhelmed by noise, busy environments, or unexpected changes. Many have developed ways of coping that hide their difficulties from the people around them.
For some people, receiving an autism diagnosis brings a sense of relief. It helps them make sense of experiences they have carried for years. Instead of asking, "What's wrong with me?" they begin asking, "Why does my brain work differently?" That shift can be incredibly powerful.
Understanding autism is not about placing people into boxes. It is about understanding how someone experiences the world and identifying the support that may help them thrive.
What Is Autism Spectrum Disorder?
Autism Spectrum Disorder, often called autism or ASD, is a neurodevelopmental condition that affects the way a person experiences, understands, and responds to the world around them.
The word "spectrum" is important because autism does not look the same for everyone.
Some autistic people need significant daily support. Others live independently, build successful careers, and manage busy family lives. While they may share some characteristics, their experiences can be very different.
Autism can affect social communication, relationships, sensory processing, flexibility, routines, interests, and the way information is understood and processed.
One of the biggest misconceptions about autism is that it is something people can always see. In reality, many autistic people become highly skilled at masking their differences. They learn social rules, study other people's behaviour, and develop strategies to fit in. While this can help them navigate social situations, it often comes at a big emotional cost.
Many adults tell us they feel exhausted after social events, meetings, family gatherings, or situations where they have spent hours trying to appear comfortable while internally feeling overwhelmed.
Signs of Autism in Adults and Children
Autism can present differently depending on a person's age, personality, environment, and life experiences.
For children, signs may include difficulties with social communication, intense interests, sensory sensitivities, emotional regulation challenges, or a strong preference for routines and predictability. Parents sometimes describe their child as becoming very distressed when plans change unexpectedly or struggling to understand social situations that other children seem to navigate naturally.
For adults, the signs are often more subtle. Many have spent years adapting to the expectations around them. They may appear socially confident but find social interactions draining. They may rehearse conversations beforehand, analyse interactions afterwards, or feel uncertain about unspoken social rules.
Some adults describe feeling as though everyone else received a handbook explaining how social relationships work, while they were left trying to work it out on their own.
Another common experience involves sensory differences. Bright lights, loud noises, crowded spaces, certain textures, or strong smells may feel far more intense than they do for other people. While others may barely notice these experiences, autistic people can find them overwhelming or exhausting.
These differences do not mean someone is broken or incapable. They simply reflect a different way of experiencing and processing the world.
Could I Be Autistic and Not Know It?
This is one of the most common questions adults ask.
Many people assume autism would have been identified during childhood if it were present. However, we regularly meet adults who are exploring autism for the first time in their twenties, thirties, forties, and beyond.
There are many reasons why autism can be missed.
Some people develop strong coping strategies. Others perform well academically and therefore avoid attracting attention. Many women and girls were overlooked because their presentation did not match the stereotypes that shaped autism awareness for many years.
Often, adults begin questioning whether they may be autistic after seeing information online, reading another person's experience, or supporting their own child through an assessment process.
As they learn more, they begin recognising patterns that have been present throughout their lives. They may remember always feeling different, struggling to fit in socially, becoming overwhelmed in busy environments, or needing far more downtime than other people after social interactions.
While these experiences do not automatically mean someone is autistic, they are common reasons people start exploring the possibility.
Autism in Women: Why Many Women Are Diagnosed Later in Life
Historically, autism research focused heavily on boys.
As a result, many women and girls were not identified because their traits looked different from what professionals expected to see.
Many women become skilled at observing and copying social behaviour. They may force themselves to maintain eye contact, rehearse conversations before social events, or carefully monitor their behaviour in order to fit in. From the outside, they often appear socially capable. Internally, they may feel exhausted by the effort involved.
This ability to mask can delay recognition for many years.
We often hear women describe feeling as though they have spent their entire lives trying to fit into environments that never felt natural to them. Some receive diagnoses only after one of their children is assessed. Others begin exploring autism after years of anxiety, burnout, or mental exhaustion that never seemed fully explained.
For many women, understanding autism helps them make sense of experiences they have carried for decades.
