Scientists have discovered that it may be possible to spot signs of dementia as early as nine years before patients receive an official diagnosis. The findings raise the possibility that, in the future<\/strong>, at-risk people could be screened to help select those who could benefit from interventions or help identify patients suitable for clinical trials for new treatments.<\/p>\n\n\n\n

Researchers at Cambridge University published the study funded by the Medical Research Council with support from the NIHR Cambridge Biomedical Research Centre in Alzheimer\u2019s & Dementia: The Journal of the Alzheimer\u2019s Association.<\/p>\n\n\n\n

\u201cfor some people who go on to develop Alzheimer\u2019s disease, memory and thinking problems can begin up to nine years before they receive a diagnosis\u201d<\/p>

\u201cThis opens up the possibility of screening programmes in the future to help identify people at risk and who may benefit from interventions, and identify more people suitable for clinical trials for new dementia treatments, which are both so desperately needed.\u201d<\/p>Associate director of research at the Alzheimer\u2019s Society, Dr Richard Oakley<\/em> said<\/cite><\/blockquote>\n\n\n\n

In the study, researchers analysed data from the UK Biobank and found impairment in several areas, such as problem solving and number recall, across a range of conditions, years before patients received an official diagnosis.<\/p>\n\n\n\n

\u201cWhen we looked back at patients\u2019 histories, it became clear that they were showing some cognitive impairment several years before their symptoms became obvious enough to prompt a diagnosis. The impairments were often subtle, but across a number of aspects of cognition.”<\/p>

\u201cThis is a step towards us being able to screen people who are at greatest risk \u2013 for example, people over 50 or those who have high blood pressure or do not do enough exercise \u2013 and intervene at an earlier stage to help them reduce their risk.\u201d<\/p>The study\u2019s first author, Nol Swaddiwudhipong, said<\/cite><\/blockquote>\n\n\n\n

There are currently very few effective treatments for dementia. Experts say this is partly because the condition is often diagnosed only once symptoms appear, whereas the underlying issue may have begun years or even decades earlier<\/strong>.<\/p>\n\n\n\n

That means that by the time patients take part in clinical trials, it can already be too late in the disease to alter its course. Until now, it has been unclear whether it could be possible to detect changes in brain function before the onset of symptoms.<\/p>\n\n\n\n

As well as collecting information on health and disease diagnoses, researchers collected data from a range of tests, including problem solving, memory, reaction times and grip strength, as well as data on weight loss and gain and on the number of falls experienced.<\/p>\n\n\n\n

This allowed researchers to see whether any signs were present at baseline, when measurements were first collected between five and nine years before diagnosis.<\/p>\n\n\n\n

People who went on to develop Alzheimer\u2019s scored more poorly compared with healthy individuals when it came to problem solving tasks, reaction times, remembering lists of numbers, and memory. According to the study, they were also more likely than healthy adults to have had a fall in the previous 12 months.<\/p>\n\n\n\n

\u201cPeople should not be unduly worried if, for example, they are not good at recalling numbers. Even some healthy individuals will naturally score better or worse than their peers. But we would encourage anyone who has any concerns or notice that their memory or recall is getting worse to speak to their GP.\u201d<\/p>The senior author from Cambridge\u2019s Department of Clinical Neurosciences, Dr Timothy Rittman<\/em> said<\/cite><\/blockquote>\n","protected":false},"excerpt":{"rendered":"Scientists have discovered that it may be possible to spot signs of…\n","protected":false},"author":3,"featured_media":934,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_mi_skip_tracking":false},"categories":[18],"tags":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/posts\/933"}],"collection":[{"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/comments?post=933"}],"version-history":[{"count":3,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/posts\/933\/revisions"}],"predecessor-version":[{"id":938,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/posts\/933\/revisions\/938"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/media\/934"}],"wp:attachment":[{"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/media?parent=933"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/categories?post=933"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/yareport.com\/index.php\/wp-json\/wp\/v2\/tags?post=933"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
