Learn how to identify olfactory dysfunction, a symptom of Sensory Processing Disorder (SPD), involving sensitivity to smells or sensory seeking certain aromas.
Children with autism disorder or fragile X syndrome may also show dysfunction of the olfactory sense, with most likely a coexisting sensory disorder. You might notice the child seeks or dislikes certain smells.
I have worked with individuals that would often try to smell hands when engaged in a hand shake, try to sniff their sibling's dirty diaper or inappropriately put their face too close to another person in effort to smell that person. This can be very uncomfortable for the opposite individual, but can unfortunately be a symptom of olfactory dysfunction.
Other symptoms include(1):
A. Hypersensitivity of the olfactory sense
B. Hyposensitivity of the olfactory sense
C. Sensory Seeking olfactory stimuli
It is usually recommended when around individuals with olfactory dysfunction or a diagnosis of sensory processing disorder, pervasive developmental disorder, or possibly even signs of ADHD, to avoid wearing strong perfumes.
This is because of the possibility that the individual may have some sensitivity to smells and could base whether or not they like you on the smell of your perfume. It could also be very irritating and cause the child to have a temper tantrum or meltdown for what seems to be no apparent reason.
Treatment for olfactory dysfunction, like other sensory processing disorders, may include work with an occupational therapist developing a sensory diet and environmental modifications.
