GAINESVILLE, Fla. --- A dollop of peanut butter and a ruler can be used to confirm a diagnosis of early stage Alzheimer's disease, University of Florida Health researchers have found. Jennifer Stamps, a graduate student in the UF McKnight Brain Institute Center for Smell and Taste, and her colleagues reported the findings of a small pilot study in the Journal of the Neurological Sciences. Stamps came up with the idea of using peanut butter to test for smell sensitivity while she was working with Dr. Kenneth Heilman, the James E. Rooks distinguished professor of neurology and health psychology in the UF College of Medicine's department of neurology.She noticed while shadowing in Heilman's clinic that patients were not tested for their sense of smell. The ability to smell is associated with the first cranial nerve and is often one of the first things to be affected in cognitive decline. Stamps also had been working in the laboratory of Linda Bartoshuk, the William P. Bushnell presidentially endowed professor in the College of Dentistry's department of community dentistry and behavioral sciences and director of human research in the Center for Smell and Taste.
"Dr. Heilman said, 'If you can come up with something quick and inexpensive, we can do it,'" Stamps said.
She thought of peanut butter because, she said, it is a "pure odorant" that is only detected by the olfactory nerve and is easy to access.
Fascinating study, and anything new we can learn will lead us a step closer to a cure! Those caring for a loved one with Alzheimer's can find additional help here: https://www.homeandhearthcare.com/services/alzheimers-dementia-care/
this was a pilot study using 24 subjects.Of the 24 patients tested who had mild cognitive impairment, which
sometimes signals Alzheimer's disease and sometimes turns out to be
something else, about 10 patients showed a left nostril impairment and
14 patients did not. The researchers said more studies must be conducted
to fully understand the implications.
Smell is just one symptom which indicates that it might be worth looking at other possible symptoms more closely. It is not an open and shut diagnosis. There are cognitive tests, dexterity tests, psychological tests ... I suspect the peanut butter test is just one part of a process, and if it helps a doctor make an earlier diagnosis, more power to them.
I'm wondering, did they take into account the circadian rythm, where the breathing normal pattern shifts from one nostril to the other every two hours? If not, this study is just half complete and needs to be repeated at the time of the switch to the other nostril!!!
Gotta wonder if our Government, in order to keep social security solvent, isn't making something that is causing seniors to die faster.. Hey!.. just a thought.. governments do love their power of the people!
How did they come to this conclusion, on what studies is this based on. was the test done on people who already have Alzheimer's. or did they test people and then waited to see how many people did this test get Alzheimer's. since I am already old, I will try the test and get back to you in a few years to see if I got it, if I still can remember.
Whoa nelly!!! You know how many people / older especially do the test and OMG I have Alzheimer's? Goober Bryce, they dont say go get expensive test but rather communicate it is absolute. So you come on Brycey
A follow-up study showing that the peanut butter test didn't work did not
generate the worldwide publicity the first study received. In 2014,
researchers at the University of Pennsylvania published findings showing
that they were unable to replicate the Florida findings. When they
tested 15 patients with Alzheimer's disease using the peanut butter
method, the Penn researchers reported that they found no difference in
the ability to detect the odor between the left and right nostrils. They
then tested 20 Alzheimer's patients with a scratch-and-sniff test they
developed themselves and here, too, found no difference in the ability
to detect the odor between the two nostrils.
Unfortunately, there is still no specific test to diagnose Alzheimer's disease. Instead, it
is typically diagnosed after doctors rule out other conditions.
I had no idea about Alzheimer's, till one of my friend shared with me that he had to live with its early stage, at his thirties. Seriously, it made me quiver with fear. I thought, what I should do if I were in his condition. I dug around and coincidentally stumbled on the web site reported the effective prevention method.
Since losing my sense of smell( I have anosmia)I was intrigued by a phenomenon that has been going around YouTube about the link between peanut butter and Alzheimer's disease. If you can smell better with the right side of your nose to the left then there is a good chance you'll get Alzheimer's. I thought I have got to have a go at this!! Bought a cheap pot of crunchy peanut butter from Morrisons and opened the lid. Not surprisingly since I have no sense of smell I couldn't smell anything left or right. So of the result ? My lack of smell sense is nothing to do with Alzheimer's or ageing as apparently of all the smells you lose when you age peanut butter is not affected. I have an MRI scan at the end of this month. They think it's going to be normal as I've had the smell problem for quite some years. Anyone else tried the test? It's really puzzling for me to work out why I can't smell but at least I know I won't get dementia in the near future :)

This is really good news, anything that would help in the treatment and detection of this horrible Alzheimer's disease. I have seen this disease live and up close and I fear I in my old age I might have to deal with the disease but promising research may beat me to the punch, and that's a good thing.
i can see dementia has already struck you, WestisOnFire...duh! if you can't detect oders, don't use / don't submit to / don't administer the test until you can detect odors. this isn't rocket science here.
Come on people. This is something that has been discovered. Why are there so many cynics in the you tube comments :-( obviously if Alzheimers or some other serious brain disease was discovered by this test then they would look for other typical symptoms CAT scan and more expensive tests. Yeesh people??
Jp Sea, this is an easy test for family members to get an early indication of possible Alzheimer's disease. If the test come up positive, the family member can investigate further. I am sorry that you have a deviated septum. Obviously you would be an exception to the typical population this test is for. You can use one of the many other tests available if you are concerned about your own risks for the disease.
+angela frost I would guess peanut butter has the right particular chemical producing the specific odor that targets the parts of the nose that gives them the meaningful measurement. I'm sure it must be something specific within the peanut butter, so you probably could use other things so long as they consist of the appropriate chemicals.
Alright this looks good but what I don't understand is why people would dislike videos like this. I watch some videos on YouTube and when I see the dislikes I just ask myself: why would anyone dislike this?
any way nice video.
Alzheimer's disease is also a "software" problem, in varying degrees. I found an eBook on Amazon called, "Alzheimer's the pride half and the half cure." It makes a lot of sense and it explains how excessive self esteem can have a very negative effect on brain function.
Of course this is from Florida, don't they know how smell works? It's normal for one nostril to be more perceptive than other.
Unless there is more data on the subject that this video shows I don't think they are up to something.
A clinic for Alzheimer in Austria uses the Greek mountain tee, herb (τσαι του βουνου=tsaee tu vounou) for treatment of A's. 2cups a day for 6months, reverses the illness to one and a half years back! As the Austrian doctor stated in Greek TV!
It seams that borrelia burgdorferi, clamydia pneumoniae, HSV 1, and mycoplasma bacteria are involved! THERE IS HOPE!
jeez. If you have the ability to smell, then it applies to how much distance per nostril the smell is detectable. OF COURSE it can't apply to all humans, because of whatever sinus or olfactory issues they may have. You're flaunting your ignorance

Yes, if you are allergic to peanut butter, you can fart then hold your head under a blanket and then close one nostril and then close the other nostril and see if the right or the left nostril will detect the odor. You would get the same results. The scientists found that patients in the early stages of Alzheimer's disease had a dramatic difference in detecting odor between the left and right nostril.
