Timely diagnosis of debilitating and often deadly brain diseases such as Alzheimer\u2019s and Parkinson\u2019s remains largely elusive, though in recent years several teams of scientists have reported potential advances based on eye scans or blood tests.<\/p>\n
In the latest advance, a Korean team has developed what they describe as an \u201cartificial intelligence-based sensor platform capable of early diagnosis of neurological disorders using saliva.\u201d<\/p>\n
The researchers claim that the system diagnosed epilepsy, schizophrenia, and Parkinson\u2019s with almost 98% accuracy.<\/p>\n
Based at Korea University, the Korea Institute of Material Science and the Catholic University of Kortea St. Vincent\u2019s Hospital, the team came up with a sensor platform that uses something called surface-enhanced Raman scattering (SERS). This is an “analytical technique that detects the unique molecular signals generated when molecules interact with light,\u201d the team says.<\/p>\n
\u201cBy precisely engineering the sensor structure, the team enabled stable detection of trace amounts of protein signals in saliva,\u201d according to Korea University, which says in a March statement that the sensor was then deployed to \u201canalyze representative neuroproteins\u201d which have in the past been linked to brain degeneration.<\/p>\n
\u201cThis study presents a point-of-care diagnostic platform that enables non-invasive early screening of neurological disorders based on structural changes in saliva proteins,\u201d says Professor Jung Ho-sang of Korea University.<\/p>\n
\u201cNeurological disorders are often difficult to diagnose at their early stages because initial symptoms are subtle or atypical,\u201d the team says after findings published in the journal Advanced Materials.<\/p>\n
\u201cIn particular, degenerative brain diseases such as Parkinson\u2019s disease and Alzheimer\u2019s disease frequently present with non-specific symptoms, leading to delayed diagnosis,\u201d they say, warning that the commonly used brain imaging and cerebrospinal fluid tests are \u201ccostly and invasive.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Timely diagnosis of debilitating and often deadly brain diseases such as Alzheimer\u2019s and Parkinson\u2019s remains largely elusive, though…\n","protected":false},"author":2,"featured_media":349669,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[85,170283,46,8138,4452,8212,44497,170282,170284,125],"class_list":{"0":"post-349668","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-technology","8":"tag-il","9":"tag-intelligence-based","10":"tag-israel","11":"tag-korea-university","12":"tag-neurological-disorders","13":"tag-parkinsons-disease","14":"tag-saliva","15":"tag-sensor-platform","16":"tag-sensor-structure","17":"tag-technology"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/349668","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=349668"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/349668\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/349669"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=349668"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=349668"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=349668"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
