Autism is a congenital neurological development disorder that affects how one understands and responds to the world. Here, we delve into what autism is and how it is experienced in everyday life.

What does it mean to have autism?

Autism – also known as autism spectrum disorder – is a broad term because symptoms and degree of impact can vary greatly from person to person. Some need a lot of support, while others live a life with few adjustments.

Autism is typically seen as a different way of thinking, communicating and understanding social situations. For example, it can be difficult to read body language or understand irony, and people may thrive on set routines and predictability.

Early signs of autism

The first signs usually appear in childhood, often before the child turns 3 years old. However, because the symptoms can vary, the diagnosis may come later in life – even in adulthood.

Common signs in children:

  • Limited eye contact
  • Delayed speech development
  • Limited interest in other children
  • Repetitive movements or routines

In adults, this can manifest as social challenges, strong interests, or a need for fixed frameworks in everyday life.

How is the diagnosis made?

The diagnosis is typically made by a psychiatrist or an assessment team who evaluates the child's or adult's behaviour, developmental history, and needs.

The assessment often involves interviews, questionnaires and observations. It's important to get a thorough assessment so that you can get the right support and understanding of your functioning.

Autism is not an illness

It is important to understand that autism is not a disease that can or should be cured. It is a different way of being in the world, and many people with autism live good and meaningful lives – with the right support systems.

Therefore, it is not about treatment, but about adaptation and understanding – both from oneself and from the surroundings.

Everyday life with autism

For many people with autism, predictability, structure, and calmness are important elements in their daily lives. It can be helpful to plan well in advance and avoid sudden changes.

Social situations can be challenging, and therefore clear frameworks and clear communication are often an advantage.

Strengths in people with autism

Many people with autism have a strong attention to detail, a good memory, or great knowledge of specific topics. Some are creative, logical thinkers, or particularly systematic – skills that are valuable in both studies and working life.

Focus on resources

Fortunately, today there is more focus on what people with autism can do, instead of what they cannot. This provides both quality of life and better opportunities.

When should you seek help?

If you notice that you or your child has difficulties with social situations, communication, or strong routines, it may be a good idea to talk to your doctor. An early assessment can provide answers and access to support.

At Doctors in Denmark, we are happy to help with the first steps in a diagnosis. You can get an appointment quickly and talk to a doctor who takes your concerns seriously.

How to support someone with autism

The most important thing is understanding and patience. Avoid pushing for social contact, and rather ask directly instead of interpreting body language.

Small adjustments in everyday life can make a big difference - for example, clear communication, calm surroundings and clear routines.
