Symptoms of Autism

The symptoms of Autism can vary from one individual to another. Healthcare providers consider autism as a spectrum disorder. This implies that there is a range of similar signs and features in different individuals with autism disorder.

One individual with autism might have mild symptoms, while another might have more severe symptoms. However, they both have the same autism spectrum disorder, also known as ASD.

Irrespective of the signs and symptoms, some certain behaviours and actions are common in Autism Spectrum Disorder and could show that a person has ASD.

Caregivers and parents who notice these symptoms in their children should speak to their kid’s health care provider about ASD and screening the child for autism.

What is autism?

What are the main symptoms of Autism?

The main symptoms of Autism are difficulties with social communication and repetitive, restricted behaviours.

Symptoms of ASD might:

  • Start in early childhood (although they might not be recognized).
  • Interfere with day-to-day living.

Professional healthcare providers treat autism utilizing a checklist of criteria in the 2 categories above. They also evaluate autism symptom severity.

The autism severity scale helps in reflecting how much support an individual requires for daily function. It’s advised that you seek medical help once you notice the symptoms. So, the case won’t lead to a severe one. 

Several people with ASD have sensory issues. These usually involve under- or over-sensitivities to lights, sounds, pain, smells, tastes, touch, and other stimuli.

1. Symptoms of Autism: difficulties with social communication


One of the signs of Autism is the difficulty of social communication. Adults and children with autism have challenges with verbal as well as non-verbal communication. For instance, they might not understand or properly use:

  • Gestures.
  • Spoken language.
  • Eye contact.
  • Voice Tone.
  • Facial expressions.

Other social challenges could include challenges with:

  • Recognizing intentions and emotions in others.
  • Recognizing one’s emotions.
  • Taking turns in a conversation.
  • Expressing emotions.
  • Feeling submerged in social situations.

2. Repetitive and restricted behaviours

Repetitive and restricted behaviours vary greater across ASD. Those can include the following:

  • Staring at spinning objects or lights.
  • Repetitive body movements such as flapping, rocking, running back and forth, spinning, etc.
  • Ritualistic behaviours such as touching objects repeatedly in a set order or lining up objects.
  • Repetitive motions with different objects such as shaking sticks, spinning wheels, flipping levers, etc.
  • Extreme or narrow interests in certain topics.
  • Need for resistance to change/unvarying routines, such as meal menu, a route to school, same daily schedule, and clothes.
