Neurodegenerative diseases lack early and accurate diagnosis, and tests currently used for their detection are either invasive or expensive and time-consuming. This study used blood plasma to diagnose and differentiate various neurodegenerative diseases; the achieved sensitivities and specificities are equal to, or even higher than, the ones obtained by clinical\/molecular methods. Herein, we show that spectroscopy could provide a simple and robust diagnostic test. Additional work should include asymptomatic individuals for an early screening test and exploration of neurodegenerative diseases at all stages of severity.<\/jats:p>","DOI":"10.1073\/pnas.1701517114","type":"journal-article","created":{"date-parts":[[2017,9,5]],"date-time":"2017-09-05T20:40:19Z","timestamp":1504644019000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":149,"title":["Differential diagnosis of Alzheimer\u2019s disease using spectrochemical analysis of blood"],"prefix":"10.1073","volume":"114","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1353-7849","authenticated-orcid":false,"given":"Maria","family":"Paraskevaidi","sequence":"first","affiliation":[{"name":"School of Pharmacy and Biomedical Sciences, University of Central Lancashire, Preston PR1 2HE, United Kingdom;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Camilo L.
