Autism is a complex neurodevelopmental disorder that affects a person’s ability to communicate and interact socially with other people. It is estimated that around 1 in 54 children in the US are diagnosed with autism, making it more common than diabetes, cancer, and AIDS combined.

When it comes to autism, there are three main symptoms that are generally seen in those who are affected. These are difficulties with social interaction, repetitive behaviors, and communication challenges. This article will provide an overview of these three main symptoms of autism, as well as detailing some of the specific issues associated with them.

Social interaction difficulties are a hallmark symptom of autism. People with autism often have difficulty recognizing or identifying facial expressions and identifying emotions from others. This difficulty in understanding the emotions of others can make it difficult for people with autism to connect with people and build relationships.

Another main symptom of autism is repetitive behaviors. People with autism often engage in behaviors that are repetitive in nature, such as having rigid routines and exhibiting unusual interests. These behaviors can be comforting and provide a sense of security to those with autism, but can also be disruptive when they interfere with daily activities.

Finally, people with autism often have communication challenges. This can include difficulty understanding language, speaking in a proper manner, having difficulty understanding the meaning of words, and having difficulty making sense of conversations. People with autism may also have difficulties with pragmatic languages, such as understanding sarcasm or making jokes.

These are the three main symptoms of autism, and they can often be identified through diagnostic criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). In order to diagnose autism, medical professionals use a variety of assessments to evaluate the severity of the symptoms and help develop an appropriate treatment plan.

In this article, we will take a closer look at each of these three main symptoms of autism, as well as provide some tips for recognizing them and seeking treatment for those affected.
