So this is an interesting one…a new study suggests that it may be possible to diagnose autism by giving children a sniff test. Yes, that’s right, the act of smelling may be able to provide tremendous insight.
Why? As covered in the NY Times, most people instinctively alter their breathing when they come in contact with certain smells – they take a big whiff with pleasant smells and limit their breathing with foul smells. However, as discussed in this research, children with autism do not make this natural adjustment. Based on their sniff test, the researchers – who were not told which participants had autism – were able to correctly identify which children did have autism 81% of the time.
Plus, what they also found was that the further removed an autistic child’s sniff response was from the average for ‘typically’ developing children, the more severe the child’s social impairments were.
Looking back on the impact of odors, different smells definitely affected Kyle when he was younger – like smoking and garbage smells. Those smells would actually make him gag or throw up, which made it a bit tricky being out in public – he would either be holding his nose, or commenting on someone smoking, or even throwing up after walking by a smelly trash can or dumpster! (And speaking of gross smells, if Kyle heard someone let off gas, he would giggle uncontrollably – as Jenifer says, it was something!)
