Autism in a Child: Causes, Symptoms, What to Do

DNA of a cell

Autism Spectrum Disorder (ASD) is a developmental disability that affects the brain and impacts an individual’s social interactions, communication, and behavior. ASD is characterized by varying degrees of severity, with symptoms ranging from mild to severe, and is more commonly diagnosed in boys than girls.

Symptoms of ASD often manifest within the first year of life. These may include lack of eye contact, unresponsiveness to their name, or inability to communicate effectively. As children with ASD grow, they may struggle to adjust to social situations, develop and maintain friendships, or understand the expectations in academic and workspace environments.

People with ASD can also have restricted or repetitive behaviors and interests, and may have unique ways of learning or paying attention. [1][2]

Causes of Autism in Children

Autism Spectrum Disorder (ASD) is a developmental disability that affects brain development, and its exact cause remains unknown. However, scientists suggest multiple factors may contribute to ASD, including genetic conditions, environmental factors, and prenatal complications.

While ASD can sometimes be detected in children as young as 18 months, many children do not receive a diagnosis until they are older. Early diagnosis and intervention can improve outcomes, as it allows for appropriate support and resources to be provided at a crucial time in the child’s development.

Early Indicators of Autism Spectrum Disorder

Parents, caregivers, and pediatricians should be aware of the early indicators of ASD to identify any potential delays or developmental differences. Some of these early signs usually appear before the age of three include:

  1. Joint Attention: Children on the autism spectrum often show delays in, or a lack of, joint attention skills, which involve looking back and forth between an object or event and another person, connecting with that person. This is a building block for later social and communication skills.
  2. Language Delays and Differences: Almost all children with ASD experience delays in nonverbal communication and spoken language. They may use words to label objects but not to ask for things, or use words for objects before using words for people or family members. Additionally, they may repeat dialogue or phrases with the same tone of voice they heard, called echolalia.
  3. Regression in Developmental Milestones: About 25% of children later diagnosed with ASD may show a sudden or gradual loss of previously acquired language or social skills, typically between the ages of 15 and 24 months. This is called regression in skills.

If a child exhibits any of these signs, a healthcare professional should be consulted for further evaluation. Early intervention can make a significant difference in a child’s development and overall outcome for those on the autism spectrum. [5][6]

Repetitive Behaviors and Interests in Children with Autism

Repetitive behaviors and interests are typical characteristics of Autism Spectrum Disorder (ASD), as they are one of the two criteria used to define the condition according to the diagnostic manual for psychiatry. These behaviors manifest in individuals with ASD in diverse forms and varying levels of intensity, hence affecting them differently.

Autistic children exhibit repetitive behaviors that can be categorized into two groups – “lower-order” and “higher-order” behaviors. Lower-order repetitive behaviors include hand-flapping, fidgeting, body rocking, grunting, and repeating phrases. Higher-order repetitive behaviors encompass routines and rituals, insistence on sameness, and intense interests such as in train schedules or butterfly taxonomy. These behaviors, while not unique to autism, tend to be more noticeable and persist well beyond childhood in autistic individuals.

Although the primary functions of these behaviors are not entirely understood, autistic individuals have reported varying purposes for their repetitive behaviors. These may include self-soothing, generating body awareness, focusing concentration, and managing overwhelming sensations or emotions. Additionally, these behaviors may help them communicate their mental or emotional state to others.

It is essential to remember that repetitive behaviors can interfere with essential tasks, such as academic learning, and may even result in injuries. As such, understanding and addressing these behaviors in autistic children should be a priority for parents and professionals working with them. [7][8]

Challenges in Communication in Autism

Communication challenges in autistic children can manifest in different ways, such as limited speech or language skills, difficulty comprehending spoken words, and problems with nonverbal communication (hand gestures, eye contact, and facial expressions).

One common communication difficulty in children with ASD is echolalia, where they may continuously repeat words they have heard, often without fully understanding their meaning. This can make it difficult for others to understand what the child is trying to say. Some autistic children may speak using a high-pitched or robotic tone, while others may use stock phrases or mimic phrases from television programs. On the other hand, some children with ASD may display strong vocabularies and speak about specific subjects in great detail but struggle to maintain two-way conversations.

Autistic children’s behavior is often linked to their communication challenges. For instance, tantrums, self-harming behaviors, and aggression might be a child’s way of trying to communicate their needs, confusion, or emotions. To address these communication challenges, professionals and caregivers need to understand and observe the child’s current communication abilities, gradually teach new skills, and adapt their approach to suit the child’s needs. [9][10]

How Autism Affects Learning and Attention

  1. Language development: Speech and language disorders are often the first signs of autism. Children with autism may have difficulty following directions, listening, speaking, understanding, and repeating phrases. Focusing on a child’s interests and providing specialized intervention can effectively address language development issues.
  2. Social interaction: Children with autism may interact differently than typically developing children. They might struggle with maintaining eye contact and using appropriate gestures to communicate, making it difficult to develop communication and language skills. Strategies like role-playing and social stories can help build these skills.
  3. Attention span: Autism can make it challenging for a child to maintain focus, especially in noisy environments. Children with autism may have difficulty concentrating on academic topics that fall outside their range of interest. Improving engagement and minimizing distractions can help improve their focus in the classroom.
  4. High-level skills: Children with autism may develop high-level skills like organization, prioritization, and time management at different rates from typically developing children. This can affect their learning and their ability to show adults what they have learned. Working on these skills may require additional support and practice.
  5. Strengths in detail and pattern recognition: Children with autism often have a keen attention to detail, which can be a strength in learning. However, they may struggle to see the “big picture” or understand broader concepts. Presenting information in a pattern that reveals the larger idea can help them comprehend better. [11][12]

Diagnosis and Treatment of Autism Spectrum Disorder

Diagnosing ASD can be difficult, as no specific medical tests – such as blood tests – can conclusively identify the disorder. Instead, healthcare professionals rely on evaluating the child’s behavior and development to determine the presence of ASD.

Early detection of ASD plays a crucial role in providing the necessary interventions and support. Symptoms can arise as early as 18 months of age, and by age two, a diagnosis by an experienced professional is considered reliable. However, some children may not receive a diagnosis until they are older, resulting in delays in obtaining the appropriate help.

Treatment for ASD primarily aims to reduce symptoms and improve daily functioning, enhancing the quality of life. Since ASD affects individuals differently, treatment plans are tailored to suit each person’s unique needs. These plans often involve multiple professionals, including psychologists, speech therapists, and occupational therapists.

While no single cause has been identified for ASD, factors such as genetic conditions, birth complications, and environmental elements have been linked to an increased risk of developing the disorder. Further research is ongoing to better understand and address the various aspects of ASD. [13][14]

Supporting Children with Autism in School and At Home

Children with autism often face difficulties in school and home settings, but with proper support, they can thrive and reach their full potential. Early intervention and therapies, such as behavioral, educational, speech, and occupational, are tailored to each child’s needs and can greatly help in their development.

In school, teachers can create a structured environment by establishing routines and limiting distractions, allowing students with autism to feel more comfortable and secure. Providing visual cues, maintaining consistency, giving extra time for tasks, and offering positive rewards for good behavior are also beneficial strategies to support and motivate these students. Educators should be mindful of the possibility of bullying and make efforts to promote inclusivity and understanding among all students.

At home, parents play a crucial role in helping their child with autism by providing structure, safety, and understanding. They can advocate for appropriate treatments and support services, while also learning about ASD to make informed decisions for their child. Parental acceptance and encouragement can contribute to the child’s overall mental wellbeing, allowing them to grow and develop in a nurturing home environment. By taking a proactive approach and working together, parents and educators can create an optimal support system for children with autism. [15][16]
