By looking at the brain wave components of individuals with the disease, <a href=\"https:\/\/dev.inrs.ca\/en\/research\/professors\/tiago-h-falk\/\">Professor Tiago H. Falk<\/a> of INRS\u2019s Centre \u00c9nergie Mat\u00e9riaux T\u00e9l\u00e9communications has identified a promising avenue of research that may not only help diagnose the disease, but also assess its severity. This non-invasive, objective method is the subject of an <a href=\"http:\/\/www.plosone.org\/article\/info%3Adoi%2F10.1371%2Fjournal.pone.0072240\">article <\/a>in the journal <em>PLOS ONE<\/em>.<\/strong><\/p>\n\n\n\n<p>Patients with Alzheimer\u2019s disease currently undergo neuropsychological testing to detect signs of the disease. The test results are difficult to interpret and are insufficient for making a definitive diagnosis. But as scientists have already discovered, activity in certain areas of the cerebral cortex is affected even in the early stages of the disease. Professor Falk, who specialises in biological signal acquisition, examined this phenomenon and compared the electroencephalograms (EEGs) of healthy individuals (27), individuals with mild Alzheimer\u2019s (27), and individuals with moderate cases of the disease (22). He found statistically significant differences across the three groups.<\/p>\n\n\n\n<p>In collaboration with neurologists and <a href=\"http:\/\/musaelab.ca\/team-view\/francisco-j-fraga\/\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"broken_link\">Francisco J. Fraga<\/a>, an INRS visiting professor specializing in biological signals, Professor Falk used an algorithm that dissects brain waves of varying frequencies. \u201cWhat makes this algorithm innovative is that it characterizes the changes in temporal dynamics of the patients\u2019 brain waves,\u201d explains Professor Falk. \u201cThe findings show that healthy individuals have different patterns than those with mild Alzheimer\u2019s disease. We also found a difference between patients with mild levels of the disease and those with moderate Alzheimer\u2019s.\u201d<\/p>\n\n\n\n<p>To validate the model in order to eventually develop an early diagnostic tool for Alzheimer\u2019s disease, <a href=\"https:\/\/dev.inrs.ca\/en\/research\/professors\/tiago-h-falk\/\">Professor Falk\u2019s<\/a> team is sharing their algorithm on the <a href=\"http:\/\/neuroscienceaccelerator.abvsciences.com\/\">NeuroAccelerator.org<\/a> online data analysis portal. It is the first open source algorithm posted on the portal and may be used by researchers around the world to produce additional research findings.<\/p>\n\n\n\n<p>Alzheimer\u2019s disease accounts for 60% to 80% of all dementia cases in North America and is skyrocketing. This step toward the development of an early diagnostic tool that is non-invasive, objective, and relatively inexpensive is therefore welcome news for the research community. \u2666<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><br><strong>About this publication<\/strong><\/h3>\n\n\n\n<p>The article, entitled \u201c<a href=\"http:\/\/www.plosone.org\/article\/info%3Adoi%2F10.1371%2Fjournal.pone.0072240\" target=\"_blank\" rel=\"noreferrer noopener\">Characterizing Alzheimer\u2019s Disease Severity via Resting-Awake EEG Amplitude Modulation Analysis<\/a>,\u201d was published in the journal PLOS ONE on August 27, 2013.
