Autism is a neurodevelopmental 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. While some may recover from autism, there are others whose condition is too severe. Some children with autism may not respond to verbal communication. If you or a loved one has an autistic child, this Autistic Child Emergency Sticker can be placed on a vehicle in case of emergency to let responders know of your child's situation.
