Low functioning autism (LFA) refers to individuals with autism who display the most severe symptoms of Autism Spectrum Disorder (ASD) and face challenges living independently. Children with LFA find it challenging to manage their everyday life activities and face behavioral issues and cognitive difficulties across activities. They typically have restrictive, stereotypic, and repetitive behavior, such as hand flapping or rocking, and may find it difficult to learn in the traditional classroom and develop relationships. Communication is especially difficult for these individuals, and they may have trouble communicating verbally or their speech may consist of echolalia or repetition. Children with LFA may also have a low IQ (below 80) and may show symptoms of an intellectual disability. The most common behaviors of low-functioning children with autism may include self-injury, self-stimulation, over-reactivity to changes, inappropriate responses, sensory disturbances, and aggression towards others. It is important to note that each person with autism is unique and has their own strengths and abilities, and individuals with LFA may still have exceptional skills and talents called savant skills.
