(Fu et al., eBioMedicine, 2025)<\/p>\n<p>The researchers used an algorithmic approach called <a href=\"https:\/\/en.wikipedia.org\/wiki\/Dynamic_time_warping\" rel=\"nofollow noopener\" target=\"_blank\">dynamic time warping<\/a>  to standardize the duration and sequence of health issues across these thousands of database records, and find patterns that matched up between patients.<\/p>\n<p>In the mental health cluster, for example, anxiety often came first, followed by <a href=\"https:\/\/www.sciencealert.com\/brain-scans-identify-six-distinct-types-of-depression-and-anxiety\" rel=\"nofollow noopener\" target=\"_blank\">depression<\/a>, which often eventually led to Alzheimer&#8217;s. In the vascular cluster, conditions like <a href=\"https:\/\/www.sciencealert.com\/a-simple-daily-habit-could-help-lower-your-blood-pressure\" rel=\"nofollow noopener\" target=\"_blank\">hypertension<\/a> and joint disorders were common starting points on the road to Alzheimer&#8217;s.<\/p>\n<p>Across the four clusters, thousands of different individual trajectories were identified, varying in terms of their progression speeds and associated <a href=\"https:\/\/www.sciencealert.com\/can-a-healthy-lifestyle-beat-alzheimers-like-documentary-claims\" rel=\"nofollow noopener\" target=\"_blank\">Alzheimer&#8217;s risk level<\/a>. It shows just how complex the road to Alzheimer&#8217;s can be.<\/p>\n<p>&#8220;By unveiling distinct and interconnected routes to Alzheimer&#8217;s disease, this approach offers insights that may improve risk assessment, timely diagnosis, and targeted interventions,&#8221; <a href=\"https:\/\/doi.org\/10.1016\/j.ebiom.2025.105831\" rel=\"nofollow noopener\" target=\"_blank\">write<\/a> the researchers in their published paper.<\/p>\n<p>To test their findings, the team ran their model on a separate set of health records from 8,512 people.
