There is another simple explanation of Autism Spectrum Disorder that needs to be addressed. Infants, do not cuddle, do not like affection, avoid eye contact. Some do not smile or lift their arms to be picked up. They do not want to learn childhood games and activities that involve participation with other children. In addition, as these children get older, they may develop an area that produces strong strengths. For example, they may be strong in music, art, memory, mathematics, or in reading.
