Many years of been research on olfactory dysfunction, various techniques have been used and proposed for the diagnosis. Besides the psychophysical evaluation, chemosensory event-related potentials are one of the leading diagnostic tools for the olfactory dysfunction. However, those techniques have major limitations, and the clinicians mostly struggle to diagnose the olfactory dysfunction of the patients. Therefore, an unbiased tool is needed to enhance the diagnosis of olfactory dysfunction. Entropy, is a technique to measure the complexity of EEG signals during the presentation of a stimulus. This complexity may reflect the neuronal activity more precisely than the classical EEG techniques (time-amplitude and time-frequency measurements). So, in this talk, the entropy analysis will be being presented for the possible tool for the diagnosis of olfactory dysfunction. Also, previous studies and ongoing modification on those merhods will be discussed.
