Types and Severities of Autism Spectrum Disorder

High-Functioning Autism (HFA)

Individuals with HFA have milder symptoms and may have average or above-average intelligence. They often have good language skills but may struggle with social interactions and understanding social cues.

Asperger's Syndrome

Previously considered a separate diagnosis but now classified under ASD,
Asperger's Syndrome is characterized by difficulties with social interaction and nonverbal communication, alongside repetitive patterns of behavior and intense interests. Individuals with Asperger's typically have average or above-average intelligence.

Classic Autism

Also known as severe autism, individuals with classic autism often have significant challenges with communication, social interaction, and behavior. They may have intellectual disabilities and require substantial support in daily life.

Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS):

This category is used for individuals who have some symptoms of ASD but do not meet the full criteria for classic autism, Asperger's Syndrome, or other specific diagnoses. Symptoms can vary widely in severity.

The Three Levels of ASD

The severity of ASD is typically evaluated based on the level of support an individual requires in three key areas: social communication, restricted and repetitive behaviors, and sensory sensitivities. The DSM-5 outlines three levels of severity:

Level 1 (Requiring Support)

  1. Individuals with Level 1 ASD require support in social situations, communication, and flexibility. They may have mild difficulties with social interactions and may exhibit repetitive behaviors.
  2. Level 2 (Requiring Substantial Support): Individuals with Level 2 ASD require more support in social communication, behavior management, and adapting to change. They may have moderate impairments in social functioning and communication.

  3. Level 3 (Requiring Very Substantial Support): Individuals with Level 3 ASD require significant support across all areas of functioning. They have severe difficulties with social communication and interaction, often displaying limited verbal communication and highly repetitive behaviors.

Understanding the various types and severities of ASD is crucial for providing appropriate interventions and support tailored to each individual’s unique needs. 

Dispelling Myths with Autism Spectrum Disorder (ASD)

Autism Spectrum Disorder (ASD) is subject to many misconceptions that can lead to stigma and misunderstanding. Dispelling these erroneous beliefs is crucial for fostering a more inclusive and informed society.
By dispelling these myths, we can move toward a more accurate understanding of ASD, promoting acceptance and support for individuals on the spectrum and their families. Here are some key points clarifying what ASD is not:

Illustration of Number 1

MYTH 1: ASD is not caused by poor parenting

Truth: Early theories mistakenly attributed autism to cold or distant parenting styles. Today, research clearly shows that ASD is a neurodevelopmental disorder with genetic and biological factors.

Illustration of Number 2

MYTH 2: ASD is not a result of vaccines

Truth: The claim that vaccines, specifically the MMR vaccine, cause autism, has been thoroughly debunked by extensive research. No credible scientific evidence supports this claim.

Illustration of Number 3

MYTH 3: ASD is not the same for everyone

Truth: Autism is a spectrum disorder, meaning it affects individuals differently. Some may require significant support daily, while others may live independently and have successful careers.

Illustration of Number 4

MYTH 4: ASD is not a cognitive disorder

Truth: While some individuals with ASD may have intellectual disabilities, many have average or above-average intelligence. Some may excel in areas such as art, music, or mathematics.

Illustration of Number 5

MYTH 5: ASD is not a condition that people “grow out of”

Truth: ASD is a lifelong condition. While symptoms may change or improve with therapy and support, the disorder itself persists into adulthood.

Illustration of Number 6

MYTH 6: ASD is not just a childhood disorder

Truth: Although symptoms typically appear in early childhood, ASD affects individuals throughout their lives. Adults with ASD continue to need support and understanding.

Illustration of Number 7

MYTH 7: ASD is not synonymous with savant syndrome

Truth: While some individuals with ASD may have exceptional skills or talents in specific areas, this is not the case for everyone with the disorder. The portrayal of all individuals with ASD as savants is a stereotype that does not reflect the true diversity of the autism spectrum.

Illustration of Number 8

MYTH 8: ASD is not a lack of desire for social interaction

Truth: Many individuals with ASD wish to form relationships and connect with others but may struggle with social communication and understanding social cues.

Substance Use Among Individuals Autism Spectrum Disorder

Research on substance abuse in individuals with Autism Spectrum Disorder (ASD) is relatively limited compared to the general population. However, some studies and clinical observations suggest that while individuals with ASD may have a lower overall rate of substance use, those who do engage in substance abuse might face unique challenges. Here’s an overview based on the available literature:

Commonly Abused Substances:


Some adults with ASD may use alcohol to alleviate social anxiety or because of peer influence. Alcohol can exacerbate symptoms of ASD, such as difficulties with social interaction and increased behavioral problems.

Prescription Medications

Misuse of prescription medications, such as ADHD drugs (stimulants) or benzodiazepines, can occur, mainly if individuals with ASD are also diagnosed with co-occurring disorders like ADHD or anxiety. Stimulants might heighten anxiety or lead to increased stereotypic behaviors, while benzodiazepines can cause increased tolerance and dependence.


Individuals with ASD might use cannabis to self-medicate symptoms like anxiety and sensory overload or to alleviate difficulties with social interactions. While some report temporary relief, cannabis can also lead to increased stress, paranoia, and exacerbation of ASD symptoms over time.

Age and Sex-Specific Information


Substance abuse among individuals with ASD tends to become more relevant in late adolescence and adulthood, particularly as social contexts change and access to substances increases.

Gender Differences:

Males with ASD are more frequently diagnosed than females, which mirrors the general trend in ASD diagnosis. However, there is limited specific research on sex differences in substance use within this population.

Important Considerations for Treatment:

  • Lower Rates but Higher Risks: Although individuals with ASD may have lower rates of substance use, those who do engage in substance abuse might face significant risks due to their social and communication challenges, making it harder for them to seek help or access treatment.
  • Co-occurring Conditions: Individuals with ASD and co-occurring conditions such as anxiety, depression, or ADHD are at a higher risk for substance abuse. Substance use can complicate the treatment and management of both ASD and the co-occurring disorder.
  • Lack of Awareness: There might be a lack of awareness or underreporting of substance use problems among individuals with ASD due to difficulties in communication and self-reporting, as well as a possible focus on managing other aspects of ASD.

Given the complexity of ASD and the variability in how it affects individuals, more research is needed to understand the relationship between ASD and substance abuse entirely. Tailored approaches to prevention and treatment that consider the unique needs of individuals with ASD are crucial for addressing substance use in this population effectively.

The Complex Challenge of Substance Abuse in Adulthood

Final Words for Families Considering Long-Term Treatment

Autism Spectrum Disorder (ASD) encompasses a broad range of conditions, each with its unique challenges and needs. From High-Functioning Autism to Classic Autism, the spectrum reflects diverse cognitive, social, and behavioral patterns. Understanding these variations is critical for tailored support and interventions.

Meanwhile, dispelling myths about ASD is equally important to foster a more inclusive society. Misconceptions, such as ASD being caused by poor parenting or vaccines, not only spread misinformation but also hinder the progress toward understanding and acceptance.
