Autism Is Not Associated With Childhood Infections.
Infections during commencement or teens do not seem to raise the risk of autism, new research finds. Researchers analyzed delivery records for the 1,4 million children born in Denmark between 1980 and 2002, as well as two federal registries that keep track of infectious diseases sleeping. They compared those records with records of children referred to psychiatric wards and later diagnosed with an autism spectrum disorder.
Of those children, almost 7400 were diagnosed with an autism spectrum disorder. The learn found that children who were admitted to the sanitarium for an catching disease, either bacterial or viral, were more likely to receive a diagnosis of autism spectrum disorder best vito. However, children admitted to the dispensary for non-infectious diseases were also more likely to be diagnosed with autism than kids who were never hospitalized, the studio found.
And the researchers could point to no particular infection that upped the risk. They therefore conclude that babyhood infections cannot be considered a cause of autism. "We find the same relationship between hospitalization due to many different infections and autism," celebrated lead study author Dr Hjordis Osk Atladottir, of the departments of epidemiology and biostatistics at the Institute of Public Health, University of Aarhus in Denmark. "If there were a causal relationship, it should be nearby for circumscribed infections and not provide such an overall pattern of association".
The study was published in the May descendant of the Archives of Pediatrics & Adolescent Medicine. Autism is a neurodevelopmental disorder that is characterized by problems with public interaction, verbal and nonverbal communication, and restricted interests and behaviors. The frequency of autism seems to be rising, with an estimated 1 in 110 children affected by the disorder, according to the US Centers for Disease Control and Prevention.
Despite significant effort, the causes of autism wait unclear, although it's believed both genetic and environmental factors contribute, said Dr Andrew Zimmerman, principal of medical examination at the Center for Autism and Related Disorders at Kennedy Krieger Institute in Baltimore. Previous probe has suggested that children with autism are more likely to have immune system abnormalities, influential some to theorize that autism might be triggered by infections.
