Who Made Autism? Unveiling the Origins

Understanding Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects individuals from a young age. To understand ASD, it is important to explore its core symptoms and the severity levels associated with them.

Core Symptoms of ASD

Doctors look for two core symptoms when making a diagnosis of Autism Spectrum Disorder [1]. These symptoms are:

1. Social Communication and Interaction Difficulties: Individuals with ASD may have challenges in social communication and interaction. They may struggle with understanding and using nonverbal cues such as gestures, facial expressions, and tone of voice. Difficulties in maintaining conversations, taking turns, and understanding social norms are also common.

2. Restricted and Repetitive Behaviors: Another core symptom of ASD is the presence of restricted and repetitive behaviors. These behaviors can manifest in various ways, such as repetitive movements (e.g., hand flapping, rocking), insistence on routine, intense interests in specific topics, and sensory sensitivities.

Severity Levels of Symptoms

The severity levels of ASD symptoms can vary from individual to individual. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) introduced severity levels to help professionals assess the level of support individuals with ASD may require. The severity levels are as follows:

1. Level 1 - Requiring Support: Individuals with Level 1 ASD symptoms require some support to navigate social situations and may face challenges in initiating and maintaining conversations. They may also exhibit inflexible behaviors and struggle with changes to routines.

2. Level 2 - Requiring Substantial Support: Individuals with Level 2 ASD symptoms require more substantial support. Their social communication difficulties become more pronounced, making it challenging to engage in meaningful interactions. They may also demonstrate repetitive behaviors that interfere with daily functioning.

3. Level 3 - Requiring Very Substantial Support: Individuals with Level 3 ASD symptoms require very substantial support across all areas of life. They experience severe impairments in social communication and interaction, often showing minimal responsiveness to others. They may have highly restricted interests and rigid adherence to routines.

Understanding the core symptoms and severity levels of ASD is essential for early identification, diagnosis, and appropriate support for individuals with autism. It allows caregivers, educators, and healthcare professionals to tailor interventions and therapies to address the specific needs of each individual.

Causes of Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder that arises from a combination of genetic and environmental factors. The exact cause of ASD is still not fully understood, but research has provided valuable insights into its origins.

Genetic Factors

Research suggests that genetics play a significant role in the development of ASD. According to a meta-analysis of twin studies, 60 to 90% of the risk for autism is genetic. Certain changes in genes or the genome can increase the likelihood of a child developing autism. It is recommended that individuals with ASD undergo genetic testing to identify potential genetic causes and associated conditions [2].

In the majority of autism cases, multiple changes in different regions of DNA contribute to the risk of developing ASD. These DNA changes work in conjunction with various genes and environmental factors, leading to the manifestation of autism spectrum disorder [2].

Environmental Influences

While genetics play a significant role, environmental influences are also believed to contribute to the development of autism spectrum disorder. Certain factors in the environment may increase the risk of autism, although it's important to note that not everyone exposed to these factors will develop the disorder. The National Institute of Environmental Health Sciences highlights the potential impact of environmental influences on ASD [2].

The interplay between genetic and environmental factors is complex and not yet fully understood. Ongoing research aims to identify specific environmental factors that may contribute to the risk of autism, providing a more comprehensive understanding of the disorder.

Understanding the causes of autism spectrum disorder is crucial for developing effective interventions and support strategies. By recognizing the role of both genetic and environmental factors, researchers can continue to explore the intricate mechanisms underlying this complex disorder.

History of Autism Diagnosis

The understanding and diagnosis of autism have evolved over time, leading to a more comprehensive understanding of Autism Spectrum Disorder (ASD) and its various characteristics. In this section, we will explore the evolution of diagnostic criteria and the contemporary understanding of ASD.

Evolution of Diagnostic Criteria

The diagnosis of autism has undergone significant changes throughout history. In the past, autism was often misunderstood, and individuals with autism were often misdiagnosed or labeled with other conditions. It was not until the publication of the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) that autism was officially recognized as a spectrum disorder. The DSM-IV described autism as a spectrum, listing five distinct conditions, including Asperger's disorder, childhood disintegrative disorder, and Rett's syndrome, creating a spectrum of mild and more severe disorders and symptoms [3].

The DSM-V (Fifth Edition) brought further changes to the diagnostic criteria for autism. It introduced the term "Autism Spectrum Disorder" (ASD) and defined it as a persistent impairment in reciprocal social communication and social interaction, along with restricted, repetitive patterns of behavior that appear in early childhood. This definition aligned more with the modern understanding of autism as a spectrum disorder.

The shift from separate diagnoses to the broader category of ASD in the DSM-5 and ICD-11 (International Classification of Diseases, Eleventh Revision) resulted in the disappearance of concepts like Asperger syndrome. However, concerns exist regarding the risk of highly functioning individuals no longer meeting the diagnostic criteria for autism, potentially impacting their access to support and services.

Contemporary Understanding of ASD

Today, the diagnosis and understanding of autism acknowledge that the spectrum is defined by a variety of conditions and symptoms. This contemporary understanding promotes a more holistic approach to treatment and recognizes the individualism of people on the spectrum. It emphasizes that each person with autism is unique, with their own strengths, challenges, and support needs.

The contemporary understanding of ASD encourages a multidisciplinary approach to assessment and diagnosis. It takes into account various factors, including behavioral observations, standardized assessments, and input from parents, caregivers, and professionals. This comprehensive approach helps to ensure a more accurate diagnosis and allows for tailored interventions and support for individuals with autism.

As our understanding of autism continues to evolve, ongoing research and advancements in diagnostic tools will contribute to a deeper comprehension of the condition, leading to improved support and interventions for individuals with autism and their families.

Treatment Approaches for ASD

When it comes to addressing the challenges associated with Autism Spectrum Disorder (ASD), various treatment approaches can help individuals with ASD thrive and reach their full potential. These approaches focus on improving communication skills, social interactions, and overall quality of life. In this section, we will explore three common treatment approaches for ASD: behavioral therapies, developmental interventions, and educational treatments.

Behavioral Therapies

Behavioral therapies, such as applied behavior analysis (ABA), have the most evidence for treating symptoms of ASD and are widely accepted among educators and healthcare professionals according to the CDC. ABA aims to encourage desired behaviors and reduce unwanted behaviors by teaching skills in a systematic and structured manner. Two popular teaching styles within ABA are discrete trial training (DTT) and pivotal response training (PRT). These approaches focus on breaking down skills into smaller steps, providing repeated practice, and using positive reinforcement to motivate progress. Progress is tracked and measured to ensure targeted outcomes are achieved.

Developmental Interventions

Developmental interventions for ASD target specific developmental skills, such as language and physical skills, and are often combined with behavioral therapies. Speech and language therapy is a common developmental intervention for individuals with ASD. It aims to enhance speech and language understanding and use. Through various techniques and activities, speech and language therapists help individuals with ASD improve their communication skills, including expressive language, receptive language, and social communication. Developmental interventions are designed to address the unique developmental needs of each individual with ASD.

Educational Treatments

Educational treatments for ASD are provided in a classroom setting and focus on improving academic outcomes and enhancing social skills. The Treatment and Education of Autistic and Related Communication-Handicapped Children (TEACCH) method is one such approach. TEACCH emphasizes consistency, visual learning, and structured teaching. Classroom structures are adjusted to improve academic outcomes, and visual supports are utilized to aid understanding and independence. By providing clear boundaries and predictable routines, educational treatments help individuals with ASD navigate their learning environment and develop valuable skills.

It's important to note that each individual with ASD is unique, and treatment plans should be tailored to their specific needs and strengths. A combination of different approaches may be necessary to address the diverse challenges associated with ASD. Collaborative efforts among healthcare professionals, educators, and families play a crucial role in identifying the most effective treatment approaches for individuals with ASD, ensuring they receive the support they need to thrive.

Medication and Psychological Support

When it comes to managing autism spectrum disorder (ASD), a combination of medication and psychological support can be beneficial. Let's explore two key approaches: pharmacological approaches and cognitive-behavior therapy.

Pharmacological Approaches

Pharmacological approaches for ASD involve the use of medications to help manage co-occurring symptoms and conditions commonly associated with autism [5]. While there is no specific medication to treat the core symptoms of ASD, medications can be prescribed to address specific challenges that individuals with ASD may face.

Some of the symptoms and conditions that medication can target include high energy levels, inability to focus, anxiety, depression, seizures, and sleep problems. It is important to work closely with a doctor experienced in treating individuals with ASD to determine the most appropriate medication and dosage for each individual. Regular monitoring of progress and reactions is essential to ensure effectiveness and minimize potential side effects.

Cognitive-Behavior Therapy

Psychological support for individuals with ASD often includes cognitive-behavior therapy (CBT). CBT is a form of therapy that focuses on identifying goals and changing thought patterns to modify reactions to situations. It can be particularly helpful in assisting individuals with ASD in coping with anxiety, depression, and other mental health issues.

CBT aims to help individuals understand the connection between their thoughts, emotions, and behaviors. Through guided sessions, individuals learn strategies to identify and challenge negative thought patterns, develop coping skills, and manage their emotions in different situations. CBT can be adapted to suit the specific needs of individuals with ASD and can be highly effective in improving their overall well-being.

While medication and psychological support play important roles in treating individuals with ASD, it's important to note that there is no cure for autism spectrum disorder. However, early and intensive treatment can make a significant difference in the lives of many children with ASD, improving their life skills, intellectual abilities, and social skills [6].

It's crucial for parents or caregivers to work closely with healthcare professionals to determine the most appropriate treatment plan for their child with ASD. Every individual is unique, and a personalized approach is essential in addressing their specific needs and challenges.

Common Behaviors in Individuals with ASD

When considering the behaviors exhibited by individuals with Autism Spectrum Disorder (ASD), it is important to understand that they can vary widely from person to person. However, there are several common behaviors that are often observed in individuals with ASD. These include repetitive behaviors, sensory sensitivities, and challenges with emotional expression.

Repetitive Behaviors

Individuals with ASD often display repetitive behaviors or mannerisms. These behaviors can serve various functions, such as providing comfort, self-calming, or reducing anxiety. Some examples of repetitive behaviors include:

• Rocking back and forth
• Pacing in circles
• Flapping hands rapidly
• Attempting to run away
• Trying to injure themselves
• Becoming aggressive when upset, frustrated, scared, or anxious

It is important to note that these behaviors can be odd, disturbing, or dangerous, and may be a result of underlying neurological conditions associated with ASD or learned behaviors for self-soothing purposes [7].

Sensory Sensitivities

Many individuals with ASD experience sensory sensitivities, which means they may have extreme reactions to certain sensory stimuli that would not typically bother others. These sensitivities can include sensitivity to sounds, lights, textures, smells, or other stimuli that may seem overwhelming, confusing, or even painful. For example, even the uniform of a police officer, with its shiny badges, sounds from communication radios, or fabric textures, could cause discomfort for someone with ASD [7].

Emotional Expression

Individuals with ASD may exhibit atypical emotional expressions that do not always align with the situation. For instance, they may giggle repeatedly when not amused or appear extremely distressed even when being consoled or provided with what they requested. Understanding and interpreting emotions can be challenging for individuals with ASD, and their emotional responses may differ from what is expected in certain situations [7].

Additionally, individuals with ASD may appear unaware of their surroundings, which can potentially put them in dangerous situations. For example, they may stand in the street without concern for passing cars. This lack of awareness is not due to deliberate disregard but rather a challenge in processing and responding to the environment [7].

Understanding these common behaviors in individuals with ASD is essential for promoting understanding, empathy, and appropriate support for individuals on the autism spectrum. By recognizing and accommodating these behaviors, we can create inclusive environments that foster the well-being and success of individuals with ASD.
