Abstract [sv]

Tidigare forskning visar att individer med en diagnos inom

autismspektrumet (ASD) upplever en större sinneskänslighet vad gäller

hörsel, syn och känsel men få studier har undersökt lukt känsligheten. Syftet

med föreliggande studie är att få en djupare förståelse för luktfunktioner hos

vuxna med ASD.16 deltagare med ASD (14 kontroller) testades i

luktkänslighet, fri- och stödd luktidentifiering. Samtliga deltagare

självskattade även den upplevda luktkänslighet samt genomgick ett

screeningtest för autism, The adult spectrum quotient, AQ. Lukt känslighet,

fri och stödd luktidentifikation skiljde sig inte åt mellan de båda grupperna

Självskattning av luktfunktioner korrelerade signifikant positivt med AQ

poäng vilket visar att personer med högre grad av ASD också upplevde sig

som mer luktkänsliga. Föreliggande resultat påvisade att personer med

högre AQ-poäng upplevde att de hade en känsligare luktfunktion. Dock

reflekterades denna självskattade känslighet inte i de standardiserade

lukttesten där inga signifikanta skillnader mellan ASD och kontroller i

luktfunktioner påvisades.

Abstract [en]

Previous research has shown that individuals with a diagnosis within the autism spectrum

(ASD) experience a greater sensory sensitivity, but few studies have investigated the olfaction

sensitivity. The aim of the present study is to gain a deeper understanding of the olfactory

functions in adults with ASD.16 participants with ASD (14 controls) participated in the study

where sniffin sticks were used to evaluate the differences between the groups. All participants

answered a questionnaire about perceived olfaction sensitivity and the adult spectrum quotient;

AQ. Olfactory discrimination and identification (with and without cue) did not differ

between the groups, as for olfaction sensitivity, perceived pleasantness, intensity and edibility.

When it came to self-assessed olfactory sensitivity, differences were found. However, this

self-rated sensitivity did not appear in the standardized odor tests, where no significant differences

between ASD and controls odor features were detected.
