The 3 Levels of Autism


Autism is a neurodevelopmental disorder that affects the way an individual perceives and interacts with the world around them. It is characterized by difficulties in communication, social interaction, and repetitive behavior patterns. Autism Spectrum Disorder (ASD) is a broad term used to describe a range of conditions that fall under the umbrella of autism, each with different levels of severity and impact on an individual's life. In this blog post, we will discuss the three levels of autism as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).


Level 1: Requiring Support

Level 1 is the mildest level of autism, where an individual requires some support to function effectively in social situations. They may have difficulty initiating or maintaining conversations and may have limited interests or repetitive behaviors. These individuals may struggle with changes in routine or have difficulty adapting to new environments. They may also experience sensory sensitivities, which can make it challenging to tolerate certain textures, sounds, or smells.


Despite these challenges, individuals with Level 1 autism can live independently and function effectively in daily life. They may need some support in certain situations, such as navigating social interactions or managing their emotions, but with the right support and guidance, they can thrive.


Level 2: Requiring Substantial Support

Level 2 is a moderate level of autism, where an individual requires substantial support to function in social situations. These individuals may have limited verbal communication skills and may rely on nonverbal communication or alternative communication methods, such as sign language or picture exchange systems. They may struggle with social interactions and may have difficulty understanding social cues or norms.


Individuals with Level 2 autism may have a narrow range of interests and may engage in repetitive behaviors or routines. They may also have sensory sensitivities, which can make it difficult for them to tolerate certain stimuli.


These individuals may require significant support in daily life, including assistance with self-care, communication, and managing emotions. With the right support, however, they can still lead fulfilling lives and achieve their goals.


Level 3: Requiring Very Substantial Support

Level 3 is the most severe level of autism, where an individual requires very substantial support to function in social situations. These individuals may have little to no verbal communication skills and may rely on alternative communication methods, such as gestures or assistive technology. They may struggle with social interactions and may have difficulty understanding or responding to social cues.


Individuals with Level 3 autism may have limited interests and may engage in repetitive behaviors or routines. They may also have sensory sensitivities, which can be severe and overwhelming.


These individuals require significant support in all areas of daily life, including self-care, communication, and managing emotions. They may require round-the-clock care and supervision, and their ability to function independently may be severely limited.


In conclusion, the three levels of autism provide a framework for understanding the range of challenges and support needs that individuals with autism may have. It is important to remember that every individual with autism is unique, and their experiences and support needs may vary widely. With the right support and understanding, individuals with autism can live fulfilling and meaningful lives.
