Abstract

A device and system capable of quantifying olfactory perception and diagnosing the possibility of Alzheimer's disease are disclosed. According to one aspect of the present embodiment, an olfactory quantification system for objectifying and quantifying what kind of scent a subject smells is perceived as, comprising: a testing device attached to or mounted on a pre-set area of the subject to test the functional activity of the left and right prefrontal lobes; and an olfactory quantification device that analyzes the results of the test by said testing device to quantify the type of scent perceived by the subject and analyzes the activity of each prefrontal lobe to diagnose the possibility of Alzheimer's disease.

Description

Apparatus Capable of Quantifying Olfactory Sensation and Diagnosing Alzheimer's Potential The present embodiment relates to an olfactory quantification device and system capable of quantifying the scent perceived by a subject by quantifying the brain pattern of the subject smelling a scent, and diagnosing the possibility of Alzheimer's disease accordingly. The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art. There are often cases where it is necessary to determine whether a subject's sense of smell is intact, such as when identifying a dementia patient or determining whether a worker's loss of olfactory function constitutes an industrial accident. Typically, the integrity of olfactory function is assessed by providing a specific scent to the subject and listening to their response regarding what kind of scent they smelled. However, conventional methods have a problem in that the reliability of the subject's response is low. There may be cases where the subject intentionally answers with a different scent even though they have smelled and recognized the scent accurately with a specific purpose, or cases where they answer with a scent that matches the provided scent by accidentally giving a different answer even though they have recognized a scent different from the provided scent. In the past, when it was necessary to objectively determine whether a subject's sense of smell was intact, inaccurate judgments were inevitable because the determination of whether the subject had lost their sense of smell had to rely on the subject's answers.
