VOC breath testing is an emerging, non-invasive approach to detect disease-related chemical patterns in exhaled air. In Parkinson’s disease (PD), characteristic VOC profiles appear to mirror changes in metabolism, oxidative stress and the gut–brain axis—opening the door to earlier diagnosis and objective monitoring alongside motor scales and olfactory testing. Nature Why breath? Recent clinical work […]
Electrogustometry (EGM) is an objective way to measure taste function by applying tiny, precisely controlled electrical stimuli to the tongue or oral mucosa. Because EGM quantifies taste thresholds in microamps rather than relying solely on self-report with chemical solutions, it’s a powerful complement to smell (olfactory) assessment in comprehensive chemosensory clinics and research labs across […]
