The symptoms of autism in young children include lack of eye contact, not smiling back, repetitive movements such as flapping their hands, flicking their fingers or rocking their body, repetition of same phrases, lack of facial expressions, etc.
Some of the symptoms of autism in older adults include difficulty in expressing their feelings, following a strict routine and getting upset if it changes, etc.
According to the WHO, “The abilities and needs of autistic people vary and can evolve over time. While some people with autism can live independently, others have severe disabilities and require life-long care and support”.
