Olfactory detection thresholds and adaptation in adults with autism spectrum condition.

Tavassoli et al. (2012) asked adults with autism to sniff weak smells.

The team measured the weakest odor each adult could notice.

They also checked how fast the nose stopped noticing a steady smell.

Same tests were given to adults without autism for comparison.

Both groups needed the same odor strength to say "I smell something."

Both groups stopped noticing the smell after the same time.

Adults with autism showed typical olfactory detection and adaptation.

Kumazaki et al. (2019) saw the opposite in autistic kids.

Kids with autism adapted less than typical peers.

The clash is about age, not error.

Children may have immature olfactory wiring that matures by adulthood.

Tavassoli et al. (2012) also tested taste in the same adults and found clear deficits.

Smell stayed normal while taste identification dipped.

Together the lab shows chemo-sense is not globally altered in adult autism.

You can skip smell-based sensory breaks for most autistic adults.

Focus visual, auditory, or tactile supports instead.

If a client still reports odor distress, test for allergies or reflux rather than autism itself.

For kids, keep watching; repeated strong smells might stay bothersome longer.
