Early Detection of Alzheimer's Disease with Peanut Butter
'The patients were given the chance to smell the peanut butter at decremented distances until they were able to recognize the smell of peanut butter. There were also noticeable differences between the sensitivity between left and right nostrils but one thing that was clearly noticed is that Alzheimer's disease patients had less sensitivity to the smell of peanut butter, most probably due to the damage that these kind of patients suffer in the front part of the temporal lobe, a part of the brain that is used, among others, to form new memories and host the smell system."
