Autism in children: signs at 18 months, diagnosis at 4 or 5 years

In many children, the first signs of autism are already visible around 18 months. Yet they are often not diagnosed until the age of four or five, sometimes even later. In the meantime, parents are regularly sent from pillar to post, and autism has the longest waiting time of almost any mental health diagnosis.

🕒 Reading time about 8 minutesTopic: autism / children / youth / waiting time

Autism is congenital, but that does not mean that it is immediately visible. The first signals in young children are subtle: excessive crying or being very quiet, not waving or greeting, and overreacting to sounds. Parents are often the first to notice that something is different.

The problem is not the lack of signals. It is the time between the moment that parents start to worry and the moment that a diagnosis and appropriate help actually arrive. Officially, a diagnosis can be made as early as 24 months, but in practice many children do not receive it until they are four or five, sometimes later.

This page does not provide medical advice. We show the pattern that repeats itself: early signals that are present, parents who are concerned and are sent from agency to agency, and waiting times that are among the longest in all of youth mental healthcare. For a diagnosis, go to your GP, the child health clinic or the youth doctor.

How it matters

What this does to your life

For a child, a late diagnosis means missed years of appropriate support at a time when the brain is still developing most rapidly. For the family, it means years of searching without clarity, tensions between partners, and brothers and sisters who grow in a household under constant uncertainty. In addition, in teenagers, compensatory strategies that worked previously often break down during puberty.

Three groups, three patterns

Women, men and teenagers are all missed at times, but not in the same way and not for the same reason. In children, the problem is not the lack of signals, but the time to diagnosis and help.

That is exactly why this page is next to the women's and men's file, not behind it: it is its own pattern with its own approach.

Treatment in brief

What you can expect from treatment

A more detailed overview of the complete treatment route can be found on the treatment page.

Early intervention works best

The sooner appropriate help starts, the greater the development opportunities for the child. child.

Family guidance, not just child care

Parents and any siblings need support just as much as the child itself.

Educational support for school-age children

Adjustments at school, from extra guidance to a quiet workplace, often make the difference between dropping out and participate.

Recognition in brief

What you can look out for

A complete overview of recognition points is on the recognition page.

Early signals around 18 months

Consider not waving, not making eye contact, or reacting extremely strongly to sound or change.

Relapse in development

Previously acquired language or social skills that disappear again is a signal that should always be taken seriously.

Puberty as a breaking point

Characteristics that could previously be compensated for often fail in secondary education.

Why ZORGFUIBRRAND collects this

One story about a child who only received the right help at the age of five is an individual drama. Thousands of stories together show that the delay is not due to the signals, which are often there early, but to a system in which parents are sent from pillar to post and the waiting time itself is one of the longest in all of mental healthcare.

We do not ask for your child's medical file. We ask for your experience as a parent: when you first noticed something, and how long it took before help arrived.

Frequently asked questions

When do the first signs of autism appear?
For many children, they are already around 18 months old, sometimes even as a baby. Think of crying excessively or being very quiet, not waving or greeting, and reacting hypersensitively to sounds.
From what age can autism be diagnosed?
Officially from 24 months. In practice, many children are not diagnosed until they are four or five, for example when problems arise at school, sometimes even later.
How long is the waiting time for autism care in mental healthcare?
On average about 20 weeks for diagnosis and treatment, compared to about 10 weeks for most other mental healthcare diagnoses. Autism is therefore structurally one of the conditions with the longest waiting time.
Why is puberty a vulnerable period?
Compensation strategies that were sufficient in primary school often fail in secondary education due to peer pressure and social codes that are already difficult for everyone. Characteristics are then easily confused with normal adolescent behavior, ADHD, an anxiety disorder or depression.
What can I do as a parent if I am worried?
Discuss it with the child health clinic, the GP, the teacher, or Integrated Early Care: a free, nationally available collaboration of organizations that helps parents with concerns about their child's development.
Are there also files about this? autism in women or men?
Yes. Autism in women has its own pattern, especially around camouflage and late recognition: see autism in women. In adult men, it is often a matter of a late diagnosis after a major life change: see autism in men.
What Zorgfuik does and does not do?
Zorgfuik does not provide medical advice and is not a practitioner. We collect experiences to make patterns visible, such as the long road between the first signals and actual help. For a diagnosis, go to your GP, the child health clinic or the youth doctor.
