When people ask me, “What does severe autism look like?”, I usually explain that autism exists on a spectrum. 

Some children need only a little support, while others — often described as having severe autism — need a lot more help with daily life. In my experience, recognizing the signs of severe autism early can make a huge difference in getting the right support.

Common Signs of Severe Autism

Every child is different, but here are some of the most common symptoms of severe autism I see in my work with families:

Communication Challenges

Children with severe autism often have very limited speech, or they may not speak at all. Instead, they might use gestures, sounds, or behavior to express themselves. Some children l (echolalia) but struggle with conversation.

Social Difficulties

Severe autism in children often means they may avoid eye contact, show little interest in playing with peers, or seem unaware of social cues. In my sessions, I’ve seen kids prefer being alone or engage only in very specific interactions.

Repetitive Behaviors

I often notice repetitive movements like hand-flapping, rocking, or spinning objects. Children may also stick to strict routines and become very upset with even small changes.

Sensory Sensitivities

Many children with severe autism are highly sensitive to lights, sounds, textures, or smells. A crowded store or loud environment can quickly feel overwhelming.

Daily Living Skills

Severe autism can also affect independence. Some kids may need ongoing help with eating, dressing, or using the bathroom.
