At InBloom, and across my career, I’ve worked with many individuals with autism spectrum disorder (ASD) in many different capacities. Although the old adage “if you’ve seen one person with autism, you’ve seen one person with autism” holds true, I’ve noticed signs over the years that tend to be more highly correlated with autism-spectrum diagnoses than others. There are some challenges that are often associated with autism, such as picky eating, tantrum behaviors, or delayed speech development, that can be applied to many neurotypical children or those with more generalized delays. There is no single symptom or behavior that identifies all individuals with ASD, but some seem to more consistently lead to a diagnosis than others. Here is a list of Five Signs That Can Potentially Point to ASD.

Most experts assert that the vast majority of human communication is nonverbal in nature.


In most kiddos that I have diagnosed over the years, there have been significant delays in nonverbal communication including gesturing and pointing. As we go through life on a daily basis, our verbal communication is nearly constantly interwoven with nonverbal communication strategies. Most experts assert that the vast majority of human communication is nonverbal in nature. By age 18 months, most typically developing toddlers have a range of gestures that they can utilize to convey different meanings. When I don’t observe any pointing or gestures during an assessment that is usually a strong indicator for a diagnosis of potential autism spectrum disorder. 


All kids differ in the frequency at which they direct eye contact toward adults or other kids. There is a natural range of comfort with eye contact. We see this range in the adult world; some adults have a tendency to look toward other people more often than other adults. Eye contact serves as a way to connect with other people and it is among the first skills to be observed in neurotypical infants. When evaluating a child for diagnosis, I don’t just look at the presence/absence of eye contact, I’m also looking at the purposes of the eye contact and how it appears. Humans, as social beings, have a natural attraction to the eyes of other humans. When eye gaze is not observed, even during what would typically be a highly motivating time (such as requesting, seeking comfort, etc.), I may suspect autism. 


For younger children, we hope to see some social interest and engagement with both family members and those who are not in the family. If a family reports taking a child to a playground or a swimming pool and they are more interested in the plants, repetitive behaviors in the water, or specific items in the environment than they are with other children, then there is support for an ASD diagnosis. For younger children with ASD, we often see a lack of social interest. For older children, we often see interest in other children but more challenges with social boundaries and social communication.

Most humans are “hardwired” to imitate others. As we are constantly learning, imitation is one of the primary ways we expand upon our communication and behavior. Most neurotypical children imitate their caregivers and peers readily, whether they are instructed to do so or not. They may imitate people on television or animals in books. When a child struggles with imitation when instructed to do so or does not show spontaneous imitation, I view this situation as a red flag. Imitation is one of the foundational skills upon which an ABA program is often built for good reason. Without imitation, it would be challenging for any learning to take place.  


Everyone has different interests and these different interests are one of the aspects that make each of us unique. Usually, when I am completing an assessment with kiddos for ASD, I have a variety of toys and activities to engage them. When I observe kiddos who are not interested in any of the toys, are more interested in non-toy items, or have highly specific toy interests (such as looking at the sheen of a block or consistently waving the ladder of a fire truck), there is support for an autism diagnosis. In some kiddos, I’ve observed very limited play with parts of toys, such as spinning an airplane’s propeller. In others, I’ve observed interest in tablet devices or other toys to the point that they need to be moved out of view so testing can be completed. 

Although one of these signs, in itself, is not indicative of autism-spectrum disorder, if multiple signs are observed, diagnostic assessment may be warranted. This list is also not comprehensive and there are many other behaviors/skills that are assessed in a full evaluation. A full autism assessment consists of a structured observational measure, a detailed developmental history, information about day-to-day functioning, and exploration of collaborative sources of information. Using the collection of data, a diagnostic determination can be made. 

If your kiddo exhibits some of these behaviors and you would like a diagnosis, InBloom offers a comprehensive diagnosis administered by a Licensed Clinical Psychologist. The evaluation also focuses on the following areas:

  • A thorough parent interview focused on obtaining information about each child's history and day-to-day functioning.

  • Structured observations of each child's behavior, including the administration of the ADOS-2.

  • Detailed, parent-friendly reports including a diagnosis (if any) and recommendations.

  • A feedback session providing parents with the opportunity to have a conversation about each child's assessment results, diagnosis, and recommendations.




Dr. Scott Allen, Psy.D works with InBloom's team of licensed Psychologists in an effort to make high-quality comprehensive evaluations for Autism Spectrum Disorder (ASD) in young children more affordable and accessible than ever. His knowledge and experience in supporting a wide variety of individuals living with ASD makes him an essential part of our team.
