Explanation:

This is a medical condition which occurs in children especially between the ages of 2-3 depicted by a constant repetitive behavior in these affected children and the inability to interact socially with his/her peers.In most cases,it affects the expected development attitudes of children behaviour like speaking,perambulating,horse play e. t.c.And it thus further goes all the way to affect the child's communication either to his/her peers or adults.It eventually brings about isolation of the child,due to his/her inability to communicate effectively and adjust socially.
