“Children with autism have a different chemical fingerprint in their urine than non-autistic children, according to new research published tomorrow in the print edition of the Journal of Proteome Research.
The researchers behind the study, from Imperial College London and the University of South Australia, suggest that their findings could ultimately lead to a simple urine test to determine whether or not a young child has autism.
Autism affects an estimated one in every 100 people in the UK. People with autism have a range of different symptoms, but they commonly experience problems with communication and social skills, such as understanding other people’s emotions and making conversation and eye contact.
People with autism are also known to suffer from gastrointestinal disorders and they have a different makeup of bacteria in their guts from non-autistic people… The distinctive urinary metabolic fingerprint for autism identified in today’s study could form the basis of a non-invasive test that might help diagnose autism earlier. This would enable autistic children to receive assistance, such as advanced behavioural therapy, earlier in their development than is currently possible.
At present, children are assessed for autism through a lengthy process involving a range of tests that explore the child’s social interaction, communication and imaginative skills.
Early intervention can greatly improve the progress of children with autism but it is currently difficult to establish a firm diagnosis when children are under 18 months of age, although it is likely that changes may occur much earlier than this.
The researchers suggest that their new understanding of the makeup of bacteria in autistic children’s guts could also help scientists to develop treatments to tackle autistic people’s gastrointestinal problems.” (Science Blog)
