Sniff Test Can Be A Short and Quick Way to Diagnose Autism

Autism or ASD (Autism Spectrum Disorders) is a life long disease with neurological impairments. If we go deep, then according to geneticists, autism is purely genetic. Not only that, but it has been revealed that more than 500 genetic variants are responsible for this spectrum of disorders, ASD. That’s the reason why all the autistic patients are not found with identical symptoms.

These lines define what autism is with its core genetic factor, responsible to cause this neuropsychiatric disorder.

Autism is generally diagnosed by the clinicians and pediatricians, through its abnormal behavioral norms. The month, April, is already nominated as autism awareness month and many autism awareness campaigns are still going on to make people aware of this incurable neurological disorder.

Yes, autism/ ASD is incurable till now, but early diagnosis on or before the age of three can reduce the neurological as well as behavioral impairments with early interventions and therapies.

Therapies to treat autism:

There are several interventions and therapies clinicians advise to reduce autistic symptoms, which are listed below.

Behavioral interventions
Language therapy
Physical therapy
ABA (Applied Behavior Analysis)
Hyperbaric medicine/ HBOT (Hyperbaric Oxygen Therapy)

Therapies and interventions can be administered, but the main problem is proper diagnosis of an autistic patient. It has been already said that, as there are no such diagnostic parameters, clinicians only depend upon some of the abnormal behavioral norms to diagnose whether a patient is with autistic disabilities or not, though recent discoveries suggest that autism can be diagnosed using saliva.

Sniff test to diagnose autism:

Here we are going to discuss that, simply a sniff test can help us to diagnose people with autism.

This test is based on nothing but a simple autonomous regular phenomenon that we love to take good odor as long as we can, but don’t like bad odor or fishy smell. So, it is basically a smell test comparing between a control or normal individual and an autism suspected individual.

Study on sniff test:

The study on this sniff test has been published in Current Biology on Thursday, 2nd July.

A study was conducted at the Weizmann Institute of Science with 36 children, taken as samples. The experiment was of 10 minutes only. The experiment was not lengthy because it was just a smell test to get the breathing patterns or differences, when the study samples were given one tube with pleasant odor and another one with a bad rotten fish odor.

Study result:

It was seen that children with autism were taking same sniff and no reaction was found whether the autistic children were with an odor of rotten fish or of shampoo. / It was seen that children with autism behaved in the same way when sniffing the pleasant odor as well as the bad odor. No reaction was found in the autistic children,  whether they got an odor of rotten fish or of shampoo.

Smell recognition is performed by our olfactory neuronal cells. Children with autism are with neuronal impairments and there is always a chance of such children having a reduced power of recognizing a good and a bad odor.

Dr Judith Brown, member of UK’s National Autistic Society said, “In future, if these initial findings are confirmed and fully understood, differences relating to processing smell may offer an additional tool in diagnosing autism”

So, we need to be up to date with time and the latest discoveries to diagnose autism as early as possible. Early diagnosis with these effective ways only can lead to get early treatment.

Controversial but Effective therapies to treat autism:

Treatments and therapies are already listed above. The last two, ABA and HBOT are the most controversial in present days.

As many patients have reported that HBOT can reduce TBI (Traumatic Brain Injury) along with other interventions, so we should have faith on this alternative treatment, hyperbaric medicine/ HBOT, which involves the use of specially designed hyperbaric chambers.

Hyperbaric medicine/ HBOT, with its hyperbaric chambers, is used to dissolve more oxygen in body fluids (blood and plasma). After crossing the blood brain barrier, the more oxygenated blood can enhance the secretion of neurotransmitters as well as resolves the issues with impaired neuronal cells. The  olfactory neuronal cells are also a type of neuronal cells responsible for recognizing smells and odors.

Application of hyperbaric medicine with hyperbaric chamber is under controversy because it is not FDA approved to treat autism. Besides, it plays an important role in healing wounds, gas gangrene and decompression sickness. Words of common people about their experiences with hyperbaric medicine, show that it helps people not only to get rid of TBI, but also to reduce autism.
