Even though language, communication, and speech delay are important features of autism, speech delay on its own can be due to a wide range of disorders. A major difference between speech delay and autism is communication, a child with autism will have difficulty in establishing communication either verbal or non-verbal, whereas a child with speech delay will try communicating in some way through gestures or in some non-verbal way. A child with a speech delay will have social interaction as a driving factor. They like getting attention, like being held, they often mimic other people's actions, and they get bored or sad when left alone. However, the child with autism often lags in establishing meaningful social relationships.
