Her <strong>previous studies have shown that amateur boxing causes damage to nerve cells, that can take more than two weeks to heal<\/strong>. This discovery led to her being offered a place in the International Olympic Committee&#8217;s expert group for boxing-related head injuries.<\/p>\n<p>Sanna Neselius has now defended her doctoral thesis at the Sahlgrenska Academy, in which she shows that <strong>sports-related concussion heals much slower than previously known<\/strong>.<\/p>\n<h3>Four months recovery<\/h3>\n<p>&#8220;<strong>It has previously been believed that concussion heals in 7-10 days<\/strong>, and the Swedish Boxing Federation has decided the rest period to be of one month after a concussion, in order to be on the safe side. But our studies show that a concussion, such as may be experienced after being knocked out, can take more than four months to heal,&#8221; says Sanna Neselius, who is herself a former boxer.<\/p>\n<p>Further, the results show that <strong>repetitive head trauma in boxing, damages nerve cells in the brain, even though the boxer may not show any concussion symptoms.<\/strong><\/p>\n<h3>Prevent resuming too early<\/h3>\n<p><strong>Concussion is one of the most common sports-related injuries, and more athletes experience it every year<\/strong>. In recent years, focus has been directed on the effects of repeated concussions, in which athletes in such sports as ice hockey may be affected by long-term effects.<\/p>\n<p>The cerebrospinal fluid samples analysed by Sanna Neselius and her colleagues <strong>can be followed until normalization<\/strong> and thereby be a valuable tool to prevent athletes resuming sport too early.<\/p>\n<p>&#8220;The assessment today is often based on physical symptoms, neuropsychological tests, and the neurological examination of the athlete. Our studies show that <strong>these tests are not sensitive enough, nor can we rely on the athletes self-reported lack of symptoms<\/strong>. Concussion symptoms usually pass after a few days, but the neurological damage may still be present,&#8221; says Sanna Neselius.<\/p>\n<h3>Safe rehabilitation<\/h3>\n<p>She continues: &#8220;The first sample is recommended to be taken 10-14 days after the concussion. This allows us to see the magnitude of the injury, and gives an idea of how long the healing process will be. I hope that brain injury markers in the cerebrospinal fluid, and hopefully also later in blood, can be used at all levels in all sports. <strong>By this we can use individual measurements to plan and guarantee safe rehabilitation<\/strong>.&#8221;<\/p>\n<p>Sanna Neselius points out that <strong>the brains of children and adolescents are more sensitive and require longer time to heal<\/strong>.<\/p><\/blockquote>\n<p>The thesis Diagnosis and monitoring of sport-related concussion &#8212; a study in amateur boxers was defended at a disputation on May 16.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the University of Gothenburg, Sweden media release: Scientists at the Sahlgrenska Academy have shown that analysis of the cerebrospinal fluid after concussion can be used to determine the magnitude&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2014\/05\/recovery-from-sports-related-concussion-slower-than-believed\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[357,10,346],"tags":[],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/16797"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=16797"}],"version-history":[{"count":1,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/16797\/revisions"}],"predecessor-version":[{"id":16799,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/16797\/revisions\/16799"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=16797"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=16797"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=16797"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
