A study published in <em>Neurology<\/em> shows that individuals who experience this lack of awareness present a nearly threefold increase in likelihood of developing dementia within two years.<\/p>\n<p>The researchers drew on data available through the <a href=\"http:\/\/adni.loni.usc.edu\/\">Alzheimer\u2019s Disease Neuroimaging Initiative (ADNI)<\/a>, a global research effort in which participating patients agree to complete a variety of imaging and clinical assessments. When a patient reported having no cognitive problems but the family member reported significant difficulties, he was considered to have poor awareness of illness.<\/p>\n<p>Researchers then compared the poor awareness group to the ones showing no awareness problems and found that those suffering from anosognosia had impaired brain metabolic function and higher rates of amyloid deposition, a protein known to accumulate in the brains of Alzheimer\u2019s disease patients.<\/p>\n<p>A follow up two years later showed that patients who were unaware of their memory problems were more likely to have developed dementia, even when taking into account other factors like genetic risk, age, gender and education. The increased progression to dementia was mirrored by increased brain metabolic dysfunction in regions vulnerable to Alzheimer\u2019s disease.<\/p>\n<p><strong>Article:\u00a0<a href=\"http:\/\/n.neurology.org\/content\/neurology\/early\/2018\/02\/14\/WNL.0000000000005120.full.pdf\">\u201cAnosognosia predicts default mode network hypometabolism and clinical progression to dementia\u201d<\/a><\/strong><br \/>\n<strong>Reprinted from materials provided by <a href=\"https:\/\/www.mcgill.ca\/newsroom\/channels\/news\/not-being-aware-memory-problems-predicts-onset-alzheimers-disease-285116\">McGill University<\/a>.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Doctors who work with individuals at risk of developing dementia [&hellip;]<\/p>\n<a href=\"https:\/\/neurodegenerationresearch.eu\/nl\/2018\/03\/not-being-aware-of-memory-problems-predicts-onset-of-alzheimers-disease\/\">View Post<\/a>","protected":false},"author":3,"featured_media":4991,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[22],"tags":[],"class_list":["post-13187","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research-news"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
