Introduction As a child is born, the parents are anxious about the new child, hoping that everything associated with him is “normal”. The routine of the baby is closely monitored, and if any abnormality occurs, the parents start having sleepless nights, in fear of something going wrong. There are many problems associated with children nowadays, and parents have to tackle them with the toughest of times. Children as young as preschool children are also vulnerable to health disorders. A child two to six years of age, not registered in a school, is called a preschool child. Many disorders may occur in the child as he grows and two of them we will be discussing here are, “autism”, and “bipolar disorder”. They are both related to depressive confusion and have to do with the minds. Behavioral Patterns of a Preschool Child with Autism There are many different ways of looking at your preschool child, and also a diversity of methods of improving your relations with him (Huxley, R.). According to Herbert Hoover, “Children are your most valuable natural resource”. This is very true, in the sense that once you have had a child, he seems to be an asset to you, and without him, your world will be revolving around nothingness, and you will begin to feel empty. Children are whom we live for, once they come to this world, and they are one of the best experiences we have in our lives. However, if they begin to suffer from strange illnesses or disorders, or are not behaving in the way they should at a certain age, they start giving us the creeps, that something is not quite right. These meager innocent souls may face various troubles on climbing their path to childhood, including eating or sleeping disorders, or other problems such as tantrums, and lack of ability to communicate with others, thus causing them to be insensitive. One such disorder we are looking into is called, “autism”. Autism is a disorder of the brain, which affects the following three areas of development in a child:  1. Communication,  2. Social interaction,  3. Creative or imaginative play. It begins in early childhood and continues till adulthood (Comer Children’s Hospital, University of Chicago, 2008). The preschool child is like a tornado of activities. He is restless and full of motion and loves to explore things around him. The child normally has full control over the body, which he enjoys immensely (Huxley, R.). The other developments that take place alongside include motor development (physical growth and activity), cognitive development (related to thought), emotional development, social development (reaction with others), language development, and emotional development (Huxley, R.). When the social and cognitive developments seem abnormal, the child is said to have autism. There is a noticeable difference in the behavior of the child, from about eighteen months of age. The basis of this pervasive disorder is not known and can range from high to severe in nature. The symptoms that a child of autism shows or indicates include an obvious lack of awareness, and the diagnosis is made between two to three years of age. There is a distinct impairment of communication and social interaction in autism, and the beha
