Understanding Autism and ASD
Previous Classification System
Before 2013, autism was classified into three distinct categories: Childhood Disintegrative Disorder, Classic Autism, Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), and Asperger's Syndrome (now referred to as high-functioning autism). This classification not only created confusion but also led to misinterpretations due to the subtle differences in each category. The prior system did not sufficiently address the varying levels of support that individuals with autism might require.
Introduction to ASD
In contrast, Autism Spectrum Disorder (ASD) is now categorized into three different levels under the DSM-5, which was released by the American Psychiatric Association in 2013. This new classification aims to clarify the confusion that stemmed from the previous system. The levels are structured based on the amount of support an individual may need.
ASD LevelDescriptionLevel 1Requiring support (high-functioning autism)Level 2Requiring substantial supportLevel 3Requiring very substantial support
Individuals classified as Level 1 generally maintain effective communication but need some assistance in social interactions. In contrast, those at Level 3 may face significant challenges, including limited verbal and nonverbal communication abilities, along with repetitive behaviors. This structured approach allows for better understanding and support for individuals affected by autism, making it easier to design appropriate interventions and resources.

Diagnosing Autism vs ASD
An accurate diagnosis is essential in distinguishing between autism and autism spectrum disorder (ASD). The process is influenced heavily by established criteria and systematic evaluations.
DSM-5 Criteria
For an official diagnosis of autism spectrum disorder (ASD), a child must meet specific standards outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) published by the American Psychiatric Association. The diagnosis requires problems in two key categories: social communication and restricted or repetitive patterns of behavior. Below is a table that presents the primary criteria used in the DSM-5 for diagnosing ASD:
CriterionDescriptionSocial CommunicationDifficulties in sharing emotions, understanding nonverbal cues, or maintaining conversations.Restricted/ Repetitive BehaviorEngaging in repetitive movements, insistence on sameness, or highly focused interests.
Meeting these criteria lays the foundation for further assessments.
Diagnostic Process
Diagnosis of autism spectrum disorder involves a two-stage process. Initially, pediatricians assess children during well-child visits at 18 and 24 months. When concerns arise, further evaluations may be conducted by a multidisciplinary team that could include child psychologists, speech-language pathologists, occupational therapists, developmental pediatricians, and neurologists.
In some cases, early diagnosis utilizes advanced tools like the Cognoa ASD Diagnosis Aid, which leverages machine learning to identify developmental issues in children aged 18 months to 5 years [3]. It's important to note that the diagnosis is not based on blood tests or X-rays. Instead, it relies on observational insights of behaviors, comprehensive medical evaluations, and the description of developmental progress provided by parents [4].
The American Academy of Pediatrics recommends screening all children for ASD during routine checkups to facilitate early identification and intervention, which is crucial for positive developmental outcomes. Understanding the diagnostic process is an essential step in grasping the fundamental differences between autism and autism spectrum disorder.
Levels of Severity
The severity of Autism Spectrum Disorder (ASD) is categorized into three distinct levels, based on the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Each level outlines specific characteristics and the corresponding amount of support required for individuals.
Level 1 Characteristics
Level 1 autism, often referred to as "requiring support," is characterized by noticeable impairments in social communication. Individuals might find it difficult to initiate interactions and often respond atypically or ineffectively to social cues. An example includes someone who speaks in full sentences but struggles with back-and-forth conversations, leading to unusual or unsuccessful attempts at making friends.
CharacteristicDescriptionSocial CommunicationNoticeable impairments without supportInitiation of InteractionDifficulties in starting social engagementsResponse to Social CuesAtypical or unsuccessful reactions

Level 2 Characteristics
Level 2 autism, categorized as "requiring substantial support," shows more pronounced deficits in both verbal and nonverbal communication skills. Individuals often exhibit limited initiation of social interactions and reduced or abnormal responses to social overtures. For instance, a person might communicate using simple sentences and engage in interactions focused solely on very narrow special interests.
CharacteristicDescriptionSocial CommunicationDeficits in verbal and nonverbal skillsInitiation of InteractionLimited and often awkward attemptsResponse to Social CuesMarkedly unusual reactions

Level 3 Characteristics
Level 3 autism is defined as "requiring very substantial support." This level encompasses severe deficits in social communication skills, marked by very limited initiation of social interactions and minimal responses to social attempts from others. An illustrative case might involve an individual with few words of intelligible speech, who typically makes no efforts to interact unless given direct social commands. Such individuals often display unique strategies to meet their needs [2].
CharacteristicDescriptionSocial CommunicationSevere deficits in both verbal and nonverbal skillsInitiation of InteractionVery limited initiation unless promptedResponse to Social CuesMinimal responses to social overtures

Behavioral Characteristics
Understanding the behavioral characteristics of individuals with autism and Autism Spectrum Disorder (ASD) is key to grasping the differences between the two. This section will focus on atypical behaviors observed in ASD and sensory sensitivities often experienced by those on the spectrum.
Atypical Behaviors in ASD
Individuals with ASD may display a range of atypical behaviors. These behaviors can vary widely in nature and intensity. Common characteristics include:
Additionally, individuals may exhibit repetitive behaviors such as rocking, spinning, and flapping hands or fingers. These actions can occur alongside ritualistic behaviors, like maintaining specific routines in meals or entertainment, such as watching the same videos repeatedly.
The table below highlights some of these atypical behaviors:
Atypical BehaviorDescriptionEye ContactPoor or avoidantFacial ExpressionsDifficulty recognizing or using expressionsVoice RegulationTone may be too loud, quiet, or monotoneRepetitive ActionsRocking, spinning, hand flappingRitualistic BehaviorsEating the same foods, watching videos repeatedly
Many individuals with ASD demonstrate a variety of behaviors that can be influenced by neurological conditions or may be learned responses used for comfort or self-calming.
Sensory Sensitivities
Sensory sensitivities are another critical aspect of ASD. Many individuals on the spectrum exhibit extreme sensitivity to normal stimuli, which can lead to overwhelming or distressing experiences. They may also present unusual mannerisms, emotions, and behaviors. Below are some common sensory sensitivities experienced by individuals with ASD:
These sensitivities can manifest in different ways. For instance, an individual might react negatively to bright lights or loud noises, expressing discomfort verbally or physically. This can lead to behaviors that appear unusual or disruptive. Understanding these sensitivities is vital for supporting individuals with ASD and accommodating their needs effectively.
In summary, recognizing the behavioral characteristics of ASD, including atypical behaviors and sensory sensitivities, plays a significant role in understanding the difference between autism and autism spectrum disorder. These insights can enhance empathy and inclusivity in various settings, from homes to classrooms and communities.
Comorbidities and Challenges
Individuals with autism and autism spectrum disorder (ASD) often face a range of comorbidities and challenges. These can include various medical and behavioral issues, as well as co-occurring conditions that impact their quality of life.
Medical and Behavioral Issues
Medical issues frequently associated with autism include a variety of conditions that may require additional evaluation and treatment. Some common medical and behavioral issues found in individuals with ASD are:
The identification and management of these comorbidities are crucial. Studies show that many children with ASD experience additional health concerns that can affect their overall wellbeing [4]. A comprehensive approach, often involving consultation with healthcare professionals, is recommended to address these challenges adequately.

Co-occurring Conditions
Co-occurring conditions, which can often be found alongside autism, further complicate the profile of individuals on the spectrum. These may include:
Addressing both medical and co-occurring conditions is essential for improving the quality of life for those with autism and ASD. Healthcare providers often recommend thorough assessments and tailored treatment plans to manage these complexities effectively.

Understanding the difference between autism and autism spectrum disorder can help in recognizing the broad range of challenges and needs that individuals face.
Support and Interventions
Early Intervention Benefits
Early intervention plays a crucial role in supporting individuals diagnosed with autism or autism spectrum disorder (ASD). Research indicates that timely access to therapies and services can significantly improve a child's development, enhancing communication skills, social interaction, and adaptive functioning. When support is provided during the critical early years of development, children have a greater chance of achieving important developmental milestones [8].
The following table summarizes some key benefits of early intervention programs:
Early Intervention BenefitsDescriptionImproved Communication SkillsChildren can learn effective ways to express themselves.Enhanced Social SkillsEarly support fosters better interactions with peers and adults.Reduction in Behavioral IssuesStrategies can be implemented to manage challenging behaviors.Increased IndependenceDeveloping life skills prepares children for future autonomy.Family SupportPrograms often include training and resources for families.
Transitioning Through Life Stages
Transitioning through different life stages can present unique challenges for individuals on the autism spectrum. Autism is a lifelong condition, and the needs, strengths, and challenges of those affected may evolve as they grow. As they move from childhood to adulthood, support systems must adapt accordingly. This includes educational support, vocational training, and assistance for independent living [8].
Generally, the stages of life and associated support needs can be outlined as follows:
Life StageDevelopmental NeedsRecommended SupportEarly ChildhoodCommunication development, social skillsEarly intervention programs, special education servicesAdolescenceSelf-identity, peer relationshipsSocial skills groups, mentoring programsAdulthoodEmployment skills, independent livingVocational training, community-based servicesOlder AdulthoodHealthcare needs, social engagementSenior support services, healthcare management
Recognizing and addressing the ongoing challenges and support requirements at each developmental stage is vital for fostering success and independence in individuals with autism.
