How come some people with autism do not show signs of when they are babies?

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects a person's ability to communicate and interact with others. It is typically diagnosed in early childhood, but some people may not show signs of autism until later in life.

There are a number of reasons why some people with autism do not show signs of the disorder when they are babies. One possibility is that the symptoms of autism may be mild or subtle in some individuals, making them difficult to detect in infancy. Another possibility is that the symptoms of autism may not develop until later in childhood, as the child's brain continues to grow and develop. Finally, it is also possible that some people with autism may be misdiagnosed with another condition, such as attention deficit hyperactivity disorder (ADHD), in early childhood.

It is important to note that there is no single cause of autism. The disorder is thought to be caused by a combination of genetic and environmental factors. However, research is still ongoing to determine the exact causes of autism and why some people may not show signs of the disorder until later in life.

If you are concerned that your child may have autism, it is important to talk to your doctor or a qualified mental health professional. Early diagnosis and intervention can help your child reach their full potential.
