Excessive hyperactivity or no signs of active life at all. Many children who suffer from autism demonstrate the unpredictable behavior. Their moods may change every hour or several minutes. One minute they want to dance and jump, the other one they are sitting silently without having any desire to interact with somebody. The movements of such patients have no basis; they may start flapping their hands without any reason. People with autism frequently do so to feel safe and calm down.

Getting wild, wild, wild. Children with autism may demonstrate both very shy condition and real wilderness. They may suddenly start behaving like some wild animals: shouting, screaming, crying, trying to beat someone, etc. It is almost impossible to calm them in such situations. The worst thing is that these kids may do harm to themselves without recognizing it. That is why their parents or health care professionals should be around to help control these consequences of anger.

Obsessed with some things. Each child has a favorite item like a toy, book, or video game he tries to carry everywhere. Autistics patients are not the exception. The only difference is that they may choose a rather strange object to become obsessed with. It could be a piece of paper or a leaf. Moreover, it’s impossible to take away this ‘relict’ from them sometimes.

Extra sensitivity. The reaction of autistic people to basic touches and sounds may impress. An ordinary person knows what it feels like to touch the water, table, another person, etc. For the child with autism, it may be something scary and unexpectable. They are rather sensitive, especially to the touches of strange people. They have a different imagination, so their visual perception is also unique. A typical sun light may irritate these patients and even make them aggressive.
