Causes: As of now, all causes of ASDs remain unknown; however, scientists have been able to link some factors that may influence the risk of ASDs. The following are possible risk factors (CDC, 2013): Genetic factors have been found to greatly influence the risk of developing an ASD. Children, who have a sibling or parent with an ASD, are at a much higher risk of also having ASD. Chromosomal conditions are also common among individuals with ASD. Approximately 10% of children with ASD also have DOWN Syndrome, tuberous sclerosis, Fragile X Syndrome, or other genetic/chromosomal disorders. Certain prescription drugs taken during pregnancy, such as valproic acid and thalidomide can increase the risk of ASDs. Premature and low birth rate can increase the risk for ASDs in a small percentage of children. According to the Mayo Clinic, autism has no single, cause due to the complexity of the disease, the range of autistic disorders and the fact that no two children with autism are alike. Researchers are continuing to look at genetic and environmental factors. (Mayo, 2010). For some time has been the belief that certain vaccination can contribute to autism, specifically the MMR vaccine. There has not been enough data to confirm this link and discontinue the administration of the vaccine. (Friend, 305). Characteristics: Individuals with autism spectrum disorder (ASD) exhibit a range of characteristics. Cognitively, some individuals may experience difficulties with rote memory, theory of mind, and lack motivation. Typically ASD causes a language delay and irregular language use, which can highly affect social skills. Individuals with ASD often have difficulty interacting with others and communicate effectively. Behaviorally, individuals with ASD can demonstrate self-stimulatory behaviors, sensory problems, and great difficulty generalizing proper behavior.
