3 Levels of Autism Spectrum Disorder

On the basis of severity of symptoms ASD has 3 levels

Mild Autism

Level 1 autism may be called “Mild Autism” in layman’s language. Children who “need support” and would suffer challenges in daily life, but they can “speak in full sentences”, Level 1 autistic people are inflexible in patterns of behaviours and face difficulty to switch from one activity to the next. They have difficulty in initiating social interactions. They are not fully independent.

Moderate Autism

Level 2 autism is sometimes called “Moderate Autism“. According to the DSM-5 children requiring significant support, everyone around them will easily notice that they’re different. These people are able to speak in simple sentences, and “markedly odd” nonverbal communication (like body language and tone of voice). The same inflexible behaviours will be seen like level 1 Autism, and people with level 2 autism will find it very difficult to cope with changes. Social interactions limited to narrow special interests.

Severe Autism

Level 3 autism would be known as “Severe Autism“. According to the DSM-5, people with level 3 autism require very substantial support, might rarely speak a few words, which are very difficult to understand, and social interaction with non-autistic people is a challenging work. People have “extreme” difficulty in coping with change at this level, and their requirement for repetitive actions and routines disrupted can be painful.
