Autism is an underdevelopment disorder that affects approximately 21.7 million people worldwide. It manifests itself with impaired social interaction and communication, both verbal and non-verbal. Though it is still unclear the exact cause of autism, it may be linked to synaptic dysfunction. Those with autism are a unique set of individuals who have developed their own culture and started movements to gain awareness, tolerance, and acceptance among the population in hopes that autism will be seen as a difference rather than a disorder. If you are or know an individual with autism, this Autism Awareness Puzzle Piece Sticker is a wonderful way to spread awareness. In addition, Magnet America will donate 10% of the sales from all autism merchandise to the Autism Society of America.
