Autism is a neurodevelopmental condition where a patient faces difficulty in social interaction and communication impairments.
The degrees of autism have been defined based on the symptoms, diagnostic and statistical manual of mental diseases.
Mild autism is also known as low-level or levels one autism.
Patients with autism who have a low or mild level of the disorder have few symptoms that do not interfere with employment, education, or relationships.
Children and adults with autism who have the most severe symptoms of autism spectrum disorder (ASD) and are diagnosed with Level 3 ASD are said to have low-functioning autism.
They are often unable to live alone and will require the assistance of a guardian for the rest of their life.
