A mental illness is a medical condition that disrupts a person's thinking, feelings, moods, ability to relate to others, and daily functioning . One form of mental illness is called autism, also known as autism spectrum disorder (ASD). This is a spectrum disorder, meaning it can affect everyone differently. Autism is a complex developmental disability that becomes visible primarily during the first three years of life and is the result of a neurological disorder that affects the normal functioning of the brain. Therefore, impacting development in the areas of social interaction and communication skills. “Autism, also referred to as autism spectrum disorder or ASD, is a broad range or spectrum of brain disorders that are usually seen in young children and that decrease an individual's ability to communicate and relate emotionally to others. This disability can range from mild to severe.” (Charman) Both children and adults with autism typically show difficulties in verbal and nonverbal communication, social interactions, and play activities. Where does the world of autism come from? This term has existed for just over a hundred years and derives from the Greek word “autos” which means self. The word gives a description of how a person is removed from social interactions and is therefore isolated. The word was first used in 1911 by a psychiatrist to refer to a group of symptoms of schizophrenia. About 30 years later, US researchers began using the term to describe children with social or emotional problems. Autism is one of the fastest growing mental illnesses in the United States. This is a disability that can make daily activities difficult. One in ten autistic people cannot speak, nine out of them often have no rules...... middle of paper ......ea of ​​learning, from social and emotional awareness to the ability to process language and sensory experiences. Until more research is conducted into information about how autism affects neurological function, children and adults who have it will not be helped to make the most of their abilities. By gaining more information about the neurological differences in the autistic versus non-autistic brain, science will be fully able to understand how best to teach individuals with autism so that they can participate to their fullest potential in their lives. The effects of autism on people are immense. It basically develops from the moment of birth and would be something that the person carries with them for the rest of their life. It is hoped that with future advances in science and medicine, a cure can finally be found for these people.
