Parkinson’s disease (PD) is the second most common neurodegenerative disorder, after Alzheimer’s disease , whose quick identification will accelerate diagnosis and treatment options. According to a study published in the Journal of the American Chemical Society, paper spray ionization coupled with ion mobility mass spectrometry (PS-IM-MS) of sebum can be used to classify different classes of biomarkers for diagnosing Parkinson’s disease . The study used sebum from skin swabs of people with PD and detected 4,200 unique features, of which 500 features were specific for PD compared to the control group.
The data suggested that high molecular weight lipids differed significantly in the sebum of people with PD. Although the stages of Parkinson's can’t be detected by this three-minute, noninvasive, cost-effective method, and sample collection efficiency remains critical as well, the method…
