Summary

Neuroscent aims to analyze EEG signals induced by olfactory stimuli in individuals with normal and impaired olfactory functions, with a focus on patients with tinnitus. The study seeks to develop reliable diagnostic methods using EEG to differentiate between normosmic and hyposmic subjects during olfactory tests, potentially enhancing our understanding of the brain's response to olfactory stimuli. This 24-month interventional study with a device to be patented will involve 1000 participants and aims to establish more effective diagnostic and therapeutic tools for olfactory disorders

Interventions

DIAGNOSTIC_TEST

Sniffin'Sticks

The Sniffin' Sticks test, a validated method to evaluate olfactory functions, utilizes pen-like devices to dispense scents for testing identification, discrimination, and detection of odors. In this study, participants' responses to various scents are recorded. EEG (Electroencephalography) captures electrical activity in the brain during exposure to these odors by using an EEG cap fitted with electrodes on the scalp. This allows for the monitoring of brain wave patterns in response to olfactory stimuli. Both the Sniffin' Sticks test and EEG recordings are conducted simultaneously, providing a dual assessment of behavioral reactions and brain activity to odors. The goal of the study is to compare brain wave patterns and olfactory function in normosmic (normal smell), hyposmic (reduced smell), and tinnitus patients with and without olfactory impairments, delivering comprehensive insights into the neural basis of olfactory perception.
