Recognizing Autism – Different Ages Show Different Indicators

Recognizing autism in individuals, especially children, involves understanding a spectrum of behaviors and developmental milestones that vary significantly with age. From the earliest months of a child’s life to their teenage years and beyond, the indicators of autism can change. This can make early and accurate identification challenging for parents, teachers, and others.

Understanding these signs at various developmental stages is not just about diagnosis. It’s about creating an environment that supports growth and learning. It is crucial to approach this process with knowledge and sensitivity, as early detection and intervention can profoundly impact the lives of those on the spectrum, enabling better support and outcomes.

Learning about recognizing autism across different ages becomes a valuable tool in the arsenal of those dedicated to supporting individuals on the spectrum. Whether adapting teaching methods, adjusting home routines, or seeking specialized assistance, the insights gained from this understanding can foster a more nurturing and effective support system.

With this in mind, Blue Parachute, leaders who provide video resources backed with ABA therapy, provides this information on recognizing autism. Continue reading to learn more about detecting autism. This includes the age to test if someone is affected by autism spectrum disorder (ASD), sensory issues, and other factors that are useful in recognizing this condition. Even if you find that your loved one is not on the spectrum, the videos in the library can be helpful for other neurodevelopmental conditions such as attention-deficit hyperactivity disorder (ADHD), conduct disorders, and others.

At What Age Can Autism Be Detected?

Autism spectrum disorder (ASD) can often be detected in children by the age of 2 years, with some signs and symptoms becoming apparent even earlier. Health professionals emphasize the importance of early detection and its role in the effectiveness of interventions designed to support developmental outcomes. Research suggests that parents and caregivers are usually the first to notice their children’s developmental delays or atypical behaviors, which may prompt further evaluation.

Pediatricians may use specific screening tools during regular checkups, especially at the 18 and 24-month milestones, to identify any early signs of ASD. These early screenings are crucial for catching signs of autism since early intervention can significantly impact a child’s long-term development. In cases where ASD is suspected, a comprehensive evaluation conducted by a team of specialists, including developmental pediatricians, neurologists, and psychologists experienced in diagnosing autism spectrum disorder, is recommended to confirm the diagnosis.

Parents need to communicate openly with healthcare providers about their child’s development and any concerns they may have. Early detection and intervention can pave the way for more effective support, helping children with autism to achieve their full potential. While autism can be detected and diagnosed at a young age, evaluations and assessments can continue throughout a person’s life as needs and circumstances change.

At What Age Can a Child Be Tested for Autism?

Children can be evaluated for autism as early as 18 months of age, and some signs can be observed even earlier. Early identification and intervention are crucial for autism spectrum disorders, as they can significantly influence the child’s developmental trajectory and quality of life. Pediatricians often conduct initial screenings during well-child visits at 18 and 24 months. These screenings help identify children who might benefit from a more detailed evaluation.

If a child shows signs of developmental delays or behaviors associated with autism, further assessment by a specialist, such as a developmental pediatrician, neurologist, psychologist, or psychiatrist who has experience with ASD, may be recommended. These professionals can conduct comprehensive evaluations using various tools and criteria to diagnose autism.

It’s important to note that showing one or a few of these signs alone does not confirm an autism diagnosis. If parents or caregivers observe these indicators, they should consult with a healthcare professional who can conduct a comprehensive evaluation. Early identification and intervention can provide critical support for the child’s development. Each child is unique, and professionals can offer guidance tailored to their needs, helping them achieve their full potential.

At What Age Can Autism Be Diagnosed?

As previously stated, autism spectrum disorder can be diagnosed as early as 18 to 24 months of age. However, it’s not uncommon for a diagnosis to occur later, especially in cases where symptoms may be less obvious or when children have less access to healthcare professionals trained in early autism detection. The key to an early diagnosis often lies in vigilant observation of the child’s development by parents and pediatricians. Early indicators can include delays in speech and language, social challenges, and unusual behaviors or play patterns.

A diagnosis of autism at a younger age allows for earlier intervention, which can significantly improve outcomes for children with ASD. Early intervention programs focusing on speech therapy, behavioral therapy, and skills development are more effective when started at a younger age. It’s important to note that while early diagnosis and intervention offer the best outcomes, individuals with ASD can benefit from support and intervention at any age.

What If My Child Is Not Yet Old Enough to Be Tested?

You might have a child younger than 18 months who you think might be on the spectrum. Have you thought about what are some indicators of autism in a 15-month-old? Identifying ASD in a very young child can be challenging, as many developmental milestones vary widely among children. However, there are specific indicators that could suggest a child is on the autism spectrum.

One of the key signs includes limited use of gestures, such as pointing or waving goodbye, which are important for non-verbal communication. A 15-month-old with autism might also have a limited number of spoken words or may not respond to their name being called. These could indicate challenges with language and auditory processing.

Another indicator could be a lack of interest in social games, like peek-a-boo or other interactive play, which typically engage toddlers. They might not make as much eye contact as expected or may not look at objects when another person points at them. 

Regardless of their age, children on the autism spectrum might display repetitive behaviors, such as lining up toys in a specific order or becoming extremely focused on a single item for an extended period. They might also show unusual reactions to sensory experiences, such as being overly sensitive or indifferent to sounds, textures, or lights.

Sensory Issues Related to Autism

Some children, whether they are on the autism spectrum or not, might display sensory issues. If a child exhibits sensory issues, these situations can help determine if a child should be tested.

What if you have a young child and you are wondering, “What are some sensory issues that a 4-year-old might display?” Sensory issues in a 4-year-old can manifest in various ways. Children at this age are more interactive with their environment yet may struggle communicating discomfort or overstimulation. These sensory sensitivities often pertain to touch, sound, light, and food textures, impacting a child’s daily activities and interactions.

Sensory processing challenges can include the following:

  • An aversion to certain clothing textures or resisting wearing items that are itchy, tight, or have tags.
  • Sound sensitivity to loud noises, including from vacuum cleaners, crowded places, or unexpected sounds.
  • Visual sensitivities to bright lights or busy patterns.
  • Children might display a very limited diet, rejecting foods based on texture, color, or smell.
  • They might seek or avoid certain sensory inputs. For instance, they may constantly touch objects or people to seek tactile feedback or avoid playground equipment that requires balance and body awareness.


Understanding these sensory issues is crucial for caregivers and educators. It allows for adapting the child’s environment to reduce sensory triggers and implement strategies to help them navigate sensory experiences more comfortably. Recognizing and addressing these sensory issues early on can also pave the way for occupational therapy interventions. These should be tailored to help the child develop coping strategies and enhance their sensory processing abilities.

20-Month-Old Development Checklist

Creating a development checklist for a 20-month-old child can help parents and caregivers monitor their child’s growth and developmental milestones. At this age, children are rapidly expanding their skills across several areas, including motor skills, language, social interaction, and cognitive abilities

While each child develops at their own pace, some commonalities exist among children. Below, we list some of these milestones. If you find your child is not meeting the expectations of their age group, discuss their progress with their pediatrician. Together, you can determine the best actions to take for your child.

Motor Skills

At 20 months, children are typically becoming more active. They might start running, though their gait may still be uneven. They can climb onto furniture, kick a ball, and may begin to prefer using one hand over the other.

Language and Communication

Many 20-month-olds can say a handful of words and are starting to put two words together to form simple sentences like “more milk.” They can follow simple one-step instructions and understand many more words than they can say. Children at this age often start to name familiar objects in pictures when prompted.

Social and Emotional Development

Children may begin to show more independence and have episodes of saying “no” to express their will. They often mimic adult actions in play, like pretending to talk on the phone, while also starting to show empathy towards others in distress.

Cognitive Skills

Problem-solving becomes more evident as they work out how to play with toys in more complex ways, such as building towers of blocks and then knocking them down. They may also be interested in puzzles and recognize the names of familiar people, objects, and body parts.

Self-Care Skills

At this age, some children might show interest in self-feeding with utensils and may be able to drink from a cup without much spilling. They might also show signs of readiness for potty training, such as expressing discomfort with dirty diapers.

It’s important to remember that developmental milestones are not rigid markers. Instead, they are guidelines. Each child is unique, and variations in achieving these milestones are common. If you have concerns about your child’s development, consulting their pediatrician is always best. They can provide personalized guidance and support for your child’s growth and development.

Can Someone Grow Out of Autism?

Autism spectrum disorder is a neurodevelopmental condition characterized by a range of symptoms affecting social interaction, communication, and behavior. It’s important to understand that this is not a condition that individuals can grow out of. The symptoms and challenges associated with autism can change over time. With the proper support and interventions, many individuals with ASD can learn to manage their symptoms and lead fulfilling lives.

Interventions, therapies, and support can significantly impact an individual’s ability to cope with these challenges, leading to improvements in communication, social skills, and adaptive behaviors. These changes might lead some to believe that a person has “grown out of” their autism. However, the individual is likely learning to navigate their environment more effectively rather than outgrowing the condition.

Adaptation and growth in individuals with autism are highly individualized. Early intervention, including tailored therapies such as Applied Behavior Analysis (ABA), speech and language therapy, and occupational therapy, can make substantial differences in development and functioning. Additionally, supportive environments that understand and accommodate the unique needs of individuals with autism are crucial. While the core characteristics of autism remain, many people who are on the spectrum can achieve significant personal growth, enhanced independence, and an improved quality of life.
