7 Signs of Autism

Updated on November 7, 2024

Autism Spectrum Disorder (ASD), often known as autism, is a neurodevelopmental condition that affects a person’s communication, behaviour, and social interaction.

Early identification and intervention are crucial for people with autism to receive the support they need to thrive.

While it can manifest in various ways, some common signs can help identify people on the autism spectrum. This article will explore seven signs of autism, offering insights into how they manifest and how parents, caregivers, and educators can recognise them.

Before we proceed, It’s important to remember that these signs are not definitive and that a diagnosis should only be made by a qualified healthcare professional.

1. Delayed Speech and Language Development

Delayed speech and language development is a common early sign of autism. While every child develops differently, significant delays can be a red flag. Most children start speaking around 12 months, but those with autism may experience significant delays or difficulties in language development.

Limited Vocabulary: Some children with autism may have a limited vocabulary and may not progress beyond basic words or phrases. They might repeat the same words or sounds without using them in context.

Echolalia: This is a common behaviour where a child repeats words or phrases they have heard, often without understanding their meaning. While echolalia can be a normal part of language development, in autistic children, it may persist beyond the typical age.

Nonverbal Communication: Due to challenges with spoken language, children with autism may rely heavily on nonverbal communication, such as pointing or using gestures.

2. Difficulty with Social Interaction

Social interaction is a core area where people with autism often struggle. This difficulty can manifest in various ways, from avoiding eye contact to challenges in understanding social cues.

Avoiding Eye Contact: Many children with autism avoid making eye contact, which can make social interactions challenging. This behaviour can be an early indicator of autism, especially when combined with other signs.

Lack of Interest in Peer Relationships: While most children show interest in playing with peers, children with autism may prefer to play alone. They might not engage in typical play behaviours like sharing toys or taking turns.

Difficulty Understanding Social Cues: Children with autism often struggle to understand social cues, such as facial expressions, tone of voice, and body language, making it challenging for them to navigate social interactions.

3. Repetitive Behaviors and Routines

Repetitive behaviours and a strong preference for routines are common characteristics of autism. These behaviours can range from simple, repetitive movements to complex rituals that must be followed precisely.

Stimming refers to repetitive actions or movements, such as hand-flapping, rocking, or spinning, which are common among people with autism. These behaviours are often self-soothing and can increase when the child is stressed or overwhelmed.

Strict Adherence to Routines: Many people with autism have a strong need for routine and predictability. A disruption in their routine, such as a change in schedule or environment, can cause significant distress.

Obsessive Interests: Some children with autism develop intense, focused interests in specific topics or objects. These interests may dominate their conversations and activities, sometimes to the exclusion of other subjects.

4. Sensory Sensitivities

Sensory processing issues are frequently observed in those with autism. These sensitivities can involve any of the five senses and may lead to over- or under-reaction to sensory stimuli.

Hypersensitivity: Children with autism often exhibit hypersensitivity to sensory stimuli. This means they can become easily overwhelmed by loud sounds, bright lights, intense odours, or specific textures. For example, they might need to cover their ears in loud settings or be very particular about the clothing they wear because of how it feels on their skin.

Hyposensitivity: On the other hand, some individuals with autism might be hyposensitive, meaning they have a reduced response to sensory stimuli. They may seek out sensory experiences, such as touching objects excessively or not noticing pain when injured.

Unusual Responses to Sensory Experiences: Children with autism may exhibit unusual responses to sensory experiences, such as staring at spinning objects for long periods or smelling or licking objects.

5. Difficulty with Motor Skills

Children with autism may also exhibit difficulties with both fine and gross motor skills. These challenges can impact their ability to perform everyday tasks and participate in typical childhood activities.

Clumsiness: Some children with autism appear clumsy or uncoordinated, struggling with activities that require balance or coordination, such as riding a bike or catching a ball.

Delayed Development of Fine Motor Skills: Fine motor skills, such as writing, buttoning clothes, or using utensils, may be slow to develop in children with autism. These delays can make tasks that require manual dexterity particularly challenging.

Unusual Gait: An atypical walking pattern, such as toe-walking or an uneven gait, is sometimes observed in people with autism.

6. Unusual Patterns of Play

Play is an essential part of childhood development, but children with autism often engage in play differently than their peers. These differences can provide important clues about the presence of autism.

Lack of Imaginative Play: Many children with autism struggle with imaginative or pretend play. Instead of engaging in creative activities, they might focus on repetitive play, such as lining up toys or spinning the wheels on a toy car.

Preference for Solitary Play: While other children may seek out playmates, children with autism often prefer to play alone. They might need help understanding the concept of shared play or may have little interest in interacting with others during playtime.

Unusual Attachment to Objects: Some children with autism develop strong attachments to specific objects, such as a particular toy or household item. They may carry these objects around constantly and become distressed if they are unavailable.

7. Challenges with Emotional Regulation

Managing emotions can be particularly difficult for children with autism. This can lead to intense emotional reactions that are disproportionate to the situation.

Frequent Meltdowns: Children with autism may experience frequent meltdowns, which are intense emotional outbursts that can occur when they are overwhelmed, frustrated, or unable to communicate their needs effectively.

Difficulty Understanding Emotions: Many people with autism struggle to understand their own emotions and those of others, making it difficult for them to express their feelings or empathise.

Anxiety and Depression: Anxiety and depression are common co-occurring conditions in people with autism. The difficulties they face in navigating social interactions and sensory experiences can contribute to these emotional challenges.

Recognising the signs of autism is crucial for early intervention and support. While every child is different, the presence of multiple signs may indicate a need for professional evaluation. Early diagnosis can significantly improve outcomes for individuals with autism, helping them thrive and live fulfilling lives.
