One early warning sign of an autism spectrum disorder is the lack of natural, varied facial expressions. Leighdionne, a young girl with ASD, shows almost no change in her expression across settings and activities; rather, her face remains flat and unidimensional, making it difficult for an observer to determine her feelings.
