Often, the original diagnosis changes as the disease progresses, Vaillancourt said.<\/p>\n<p>Diffusion tensor imaging, known as DTI, is a non-invasive method that examines the diffusion of water molecules within the brain and can identify key areas that have been affected as a result of damage to gray matter and white matter in the brain. Vaillancourt and his team measured areas of the basal ganglia and cerebellum in individuals, and used a statistical approach to predict group classification. <strong>By asking different questions within the data and comparing different groups to one another, they were able to show distinct separation among disorders<\/strong>.<\/p>\n<p>&#8220;Our goal was to use these measures to accurately predict the original disease classification,&#8221; Vaillancourt said. &#8220;The idea being that if a new patient came in with an unknown diagnosis, you might be able to apply this algorithm to that individual.<\/p>\n<p><strong>He compared the process to a cholesterol test<\/strong>.<\/p>\n<p>&#8220;If you have high cholesterol, it raises your chances of developing heart disease in the future,&#8221; he said. &#8220;There are tests like those that give a probability or likelihood scenario of a particular disease group. <strong>We&#8217;re going a step further and trying to utilize information to predict the classification of specific tremor and Parkinsonian diseases.<\/strong>&#8221;<\/p>\n<p>Vaillancourt and his team are part of the National Institute of Neurological Disorders and Stroke Parkinson&#8217;s Disease Biomarkers Program, an effort that was launched in 2012 and awarded nine grants to scientists across the U.S., totaling more than $5 million in the first year. The program gives researchers access to a much broader community of individuals and patients as part of a biomarker initiative for Parkinson&#8217;s disease.<\/p>\n<p>Vaillancourt&#8217;s team is engaged in a longitudinal study at UF that will assess between 150 and 180 people over the next few years. <strong>His team will be using DTI as well as other MRI-based techniques to classify subjects and track their progression<\/strong>, he said.<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the University of Florida press release via ScienceDaily: A new University of Florida study suggests a promising brain-imaging technique has the potential to improve diagnoses for the millions of&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2013\/06\/study-suggests-brain-imaging-technique-may-help-diagnose-movement-disorders\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[10,6],"tags":[42,248],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/14142"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=14142"}],"version-history":[{"count":4,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/14142\/revisions"}],"predecessor-version":[{"id":14383,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/14142\/revisions\/14383"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=14142"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=14142"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=14142"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
