They are not deaf, but deaf to the sound; not blind, but blind to the surrounding people and things; not dumb, but do not know how to speak. Some people say that they are alien, although like the stars in the sky as pure, but also like the stars as indifferent, only living in their own world, and the world does not fit. They have a beautiful and mournful name: children of the stars. This is the autistic children, let’s get closer to autistic children, to understand their hearts. Autism is a subtype of pervasive developmental disorder that is prevalent in males and begins in infancy and early childhood. About 3/4 of the patients have significant mental retardation, which causes a huge economic and social burden to the family and society. The causes of autism are not yet fully understood. Studies have found that autism is influenced by both genetic and environmental factors, and that abnormal early brain development in autistic children may be a direct cause of autism. In addition, neurotoxic substances, nutrients, metabolites and neuroactive substances may be the etiology of autism. Some autistic patients have chromosomal abnormalities and genetic variants, while more cases show abnormalities in other areas such as gastrointestinal symptoms. Treatment of autism Because the cause of autism is still a mystery, there is no cure. However, doctors, researchers and parents of children with autism have tried a variety of treatments and have gained a lot of experience, enabling many children with autism to have the ability to participate in social life. Common treatments include behavioral interventions, special education, medication, biomedical interventions, and psychological interventions, among which behavioral interventions that use highly structured, intensive skill-based training to help children develop social and language skills, such as applied behavior analysis, are commonly used. It is important to go to a professional, regular hospital for the treatment of autism in children to avoid delaying the child’s condition. With early detection and formal interventions, it is possible for a child to reach or approach the mental level of a normal child. Therefore, parents must first have a positive and optimistic attitude, cooperate with the treatment, and help their children to train their language communication skills and communication skills, which are crucial to their children’s rehabilitation. It is the common wish of the whole society to understand autism, pay attention to autism, open a window for autistic children, and deliver love and warmth. Let’s work together to enter their heart world, listen to their hearts, and give autistic children a blue sky.
