Approximately 153,000 people in the UK live with Parkinson\u2019s disease.<\/p>\n<p>There is currently no cure for PDD, but patients can take medications called cholinesterase inhibitors to help manage symptoms.<\/p>\n<p>\u201cOur current treatments for Parkinson\u2019s disease and dementia treat the symptoms, but do not change the underlying course of the disease,\u201d Dr Stephen Pasternak, the lead author of the study, told The Standard.<\/p>\n<p>\u201cWe hope that Ambroxol, a cough medicine available over the counter in most of the world, but not in the United States or Canada, will change the course of Parkinson\u2019s disease dementia (and related diseases).\u201d<\/p>\n<p class=\"sc-feNupb cglSGO\">Parkinson&#8217;s dementia symptoms<\/p>\n<ul>\n<li>Difficulty focusing<\/li>\n<li>Difficulty making decisions<\/li>\n<li>Memory loss and forgetfulness<\/li>\n<li>Difficulty staying awake<\/li>\n<li>Disturbed sleep<\/li>\n<li>Visual hallucinations<\/li>\n<li>Delusions<\/li>\n<li>Changes in appetite<\/li>\n<li>Mood changes such as depression, anxiety and apathy<\/li>\n<\/ul>\n<p>The study, published in <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/jamanetwork.com\/journals\/jamaneurology\">JAMA Neurology<\/a>, involved 55 participants who had Parkinson\u2019s disease dementia (PDD), monitoring their memory, psychiatric symptoms, and GFAP, a blood marker linked to brain damage. <\/p>\n<p>It found that GFAP increased in the placebo group but stayed stable for participants taking Ambroxol.<\/p>\n<p>As well as this, dementia symptoms worsened in the placebo group, but not for those on Ambroxol.<\/p>\n<p>Participants also showed improved cognitive performance on Ambroxo.<\/p>\n<p>\u201cIndividuals receiving placebo showed a clinically meaningful worsening in neuropsychiatric symptoms, whereas those receiving ambroxol remained stable,\u201d the scientists wrote.<\/p>\n<p>\u201cAmbroxol was safe, well-tolerated, and demonstrated target engagement,\u201d the researchers wrote. \u201cHowever, the effect of ambroxol on cognition was not confirmed.\u201d<\/p>\n<p>How could Ambroxol impact Parkinson\u2019s<\/p>\n<p>Ambroxol boosts an enzyme called GCase, which clears away waste products that accumulate in brain cells. <\/p>\n<p>The enzyme is often deficient in Parkinson\u2019s patients, causing waste to build up in brain cells, including an unwanted protein called alpha-synuclein. <\/p>\n<p>It\u2019s thought that Ambroxol may help the body reduce this waste, preventing brain damage.<\/p>\n<p>Ambroxol was first considered as a potential Parkinson&#8217;s treatment in 2009.<\/p>\n<p>In 2020, a trial funded by <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/cureparkinsons.org.uk\/\">Cure Parkinson\u2019s<\/a> and its partners showed that Ambroxol could reach the part of the brain that boosted GCase and was safe for people with Parkinson\u2019s.<\/p>\n<p> \u201cWe hope that Ambroxol, or drugs like Ambroxol, will be able to prevent the onset of Parkinson&#8217;s disease and dementia if it is given early enough,\u201d Dr Stephen Pasternak told The Standard.<\/p>\n<p>Pasternak is continuing to explore whether Ambroxol can help people suffering from Parkinson\u2019s dementia, with plans to begin a follow-up clinical trial specifically focused on cognition later this year.<\/p>\n<p>His team is currently trying to secure funding for a study focused on dementia alone. They are also working with an American company, Zywie Bio LLC, to examine analogues of Ambroxol that they hope will have better pharmacological properties.<\/p>\n<p>&#8220;If a drug like Ambroxol can help, it could offer real hope and improve lives.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"A 12-month study conducted by researchers at Lawson Research Institute found that Ambroxol helped stabilise psychiatric symptoms, improved&hellip;\n","protected":false},"author":2,"featured_media":239813,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[11],"tags":[425,105,3912,11365,93314,2343,16,15],"class_list":{"0":"post-239812","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-health","8":"tag-dementia","9":"tag-health","10":"tag-medicine","11":"tag-parkinsons-disease","12":"tag-parkinsons","13":"tag-research","14":"tag-uk","15":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114800060248996840","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/239812","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=239812"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/239812\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/239813"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=239812"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=239812"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=239812"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
