What age can you tell when a child has autism?

There is no single answer to this question, as the age at which autism can be diagnosed varies from child to child. However, most children are diagnosed with autism between the ages of 2 and 4 years old. This is because autism is a developmental disorder, and the symptoms of autism are typically more noticeable during early childhood.

Some children may show signs of autism as early as 18 months old. These signs may include:

* Lack of eye contact

* Difficulty understanding language

* Delayed speech and language development

* Repetitive behaviors

* Difficulty interacting with other children

Other children may not show any signs of autism until they are 3 or 4 years old. These signs may include:

* Difficulty understanding social cues

* Problems making friends

* Difficulty expressing emotions

* Impulsiveness

* Hyperactivity

If you are concerned that your child may have autism, it is important to talk to your doctor. Early diagnosis and treatment can help your child reach their full potential.
