When an individual experiences this form of mild brain injury, the symptoms are not generally life-threatening, but are there any lasting effects?<\/p>\n<p><strong>What Is a Concussion and How Does It Affect the Brain?<\/strong><\/p>\n<p>Although we often recognize concussion risk within sports, this form of brain trauma can also occur when individuals fall, are involved in a motor vehicle accident, or any other incident that results in impact\/rapid acceleration of the head. When someone experiences blunt force trauma, for instance, this will likely cause a <em>primary<\/em> injury.<\/p>\n<p>This means, that the initial impact caused the brain to hit the interior of one&#8217;s skull, resulting in possible contusions. When someone is suffering from a concussion, this is generally associated with <em>secondar<\/em>y injuries \u2014 some which will develop hours, or even days later.<\/p>\n<p>So, once a concussion occurs, are there lasting effects?<\/p>\n<p><strong>The Long-Term Effects of Concussions<\/strong><\/p>\n<p>If you have experienced a concussion in the past, then you are already aware of the possible short-term effects, including:<\/p>\n<ul>\n<li>Poor sleep quality<\/li>\n<li>Headaches<\/li>\n<li>Vertigo<\/li>\n<li>Ringing in your ears<\/li>\n<li>Nausea<\/li>\n<li>Vomiting<\/li>\n<li>Loss of consciousness<\/li>\n<li>Depression<\/li>\n<li>Anxiety<\/li>\n<li>Lack of focus<\/li>\n<li>Partial memory loss<\/li>\n<\/ul>\n<p>These symptoms are troublesome to say the least \u2014 but it&#8217;s the long-term effects that both researchers, physicians, and patients are concerned with. Will a concussion lead to issues with one&#8217;s emotional stability and cognitive function in their later years?<\/p>\n<p>Based on current research, it appears that there are possible symptoms that can last months \u2014 if not years. Unfortunately, concussions are also cumulative in nature, making the recovery process even more challenging. This means, that if you suffer from one concussion, it&#8217;s generally easier that you&#8217;ll suffer from another.<\/p>\n<p>Although most individuals successfully recover from a single concussion, each repeated concussion can result in more severe effects \u2014 both short- and long-term. In this sense, please be aware of the possible consequences of temporary brain injury.<\/p>\n<p>In addition, some of the possible long-term symptoms include, but are not limited to:<\/p>\n<p><strong>Depression <\/strong><\/p>\n<p>Unfortunately, approximately half of all people who suffer from a traumatic brain injury, are affected by depression within the first year. Of these individuals, more than half will also suffer from increased anxiety. This link has been well-established, as seen in a number of studies.<\/p>\n<p><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24322397\">Within one key study<\/a>, published in the <em>American Journal of Psychiatry<\/em>, it was found that following a head injury, patients increased their risk of a mental health disorder by up to 439 percent. Being the largest study of its kind, it was found that of those who experienced head trauma, they were:<\/p>\n<ul>\n<li>65 percent more likely to be diagnosed with schizophrenia<\/li>\n<li>59 percent more likely to suffer from depression<\/li>\n<li>28 percent more likely to develop bipolar disorder<\/li>\n<li>439 percent more likely to experience organic mental disorders \u2014 resulting in reduced mental function<\/li>\n<\/ul>\n<p>After experiencing head trauma, such as a concussion, the greatest risk of reduced mental health generally occurs within the first year. With that being said, even after 15 years have passed, these individuals continue to experience an elevated risk.<\/p>\n<p>Of course, each individual case is unique, but overall, <a href=\"https:\/\/braintest.com\/anxiety-depression-cause-dementia\/\">symptoms of depression<\/a> are generally due to:<\/p>\n<ul>\n<li><strong>Physical changes<\/strong> \u2014 After a brain injury, some individuals will experience damage within the areas of their brain that regulate emotion. Patients may also suffer from a neurochemical imbalance.<\/li>\n<\/ul>\n<ul>\n<li><strong>Emotional impact<\/strong> \u2014 As an individual tries to adjust, some struggle to cope with both temporary and lasting disability.<\/li>\n<\/ul>\n<ul>\n<li><strong>Predisposition<\/strong> \u2014 Some patients are already faced with an increased risk of depression due to genetic factors or personal history. This predisposition may be more easily activated following head trauma.<\/li>\n<\/ul>\n<p>Unfortunately, an increased risk of depression is also typically associated with an increased risk of suicide. Recently, researchers discovered that even mild concussions may lead to detrimental effects. Of those who have experienced a concussion, their long-term risk of suicide increases threefold.<\/p>\n<p><strong>Long-term Memory Loss <\/strong><\/p>\n<p>More recently, researchers have been investigating the link between concussions and the possible long-term effects on cognition. It has long been established that this type of head injury can lead to both short- and long-term memory loss, but it&#8217;s only recently that researchers found a clear connection to Alzheimer&#8217;s.<\/p>\n<p><a href=\"https:\/\/academic.oup.com\/brain\/article-lookup\/doi\/10.1093\/brain\/aww344\">Within a 2017 study<\/a>, it was found that concussions do, in fact, accelerate cognitive decline and Alzheimer&#8217;s-related brain atrophy. More specifically, this associated risk was based on those who are at genetic risk for this condition. Published in <em>Brain<\/em>, it was found that:<\/p>\n<ul>\n<li>Of the 160 war veterans studied, it was found that concussions are associated with a lower cortical thickness in brain regions, which are the first to be affected among Alzheimer&#8217;s patients.<\/li>\n<\/ul>\n<ul>\n<li>When combined with genetic risk factors, even a mild concussion may accelerate memory decline within Alzheimer&#8217;s specific areas.<\/li>\n<\/ul>\n<p>Although related brain injury research is still in infancy, researchers have long known of Chronic Traumatic Encephalopathy (CTE). Generally affecting athletes with a history of brain trauma, this degenerative disease can lead to memory loss, aggression, reduced judgement, poor impulse control, and over time, progressive dementia.<\/p>\n<p>When comparing CTE and Alzheimer&#8217;s, these two diseases may also share biological mechanisms. Both classified as <em>tauopathies<\/em>, these diseases are characterized by abnormal protein clumps, or &#8216;tau&#8217; in the brain. Toxic to neurons, these tangles are believed to encourage key behavioral and cognitive changes.<\/p>\n<p><strong>Reduced Motor Skills <\/strong><\/p>\n<p>After a concussion, it&#8217;s not uncommon for individuals to notice a decline in motor skills. Initially, most affected individuals will notice that their fine motor skills are impaired. For some, they experience issues with balance, a lack of coordination, or the ability to perform highly technical movements, such as playing the piano.<\/p>\n<p>Within a recent study, published in <em>Concussion<\/em>, researchers examined cognitive-motor integration. What they found, was that after analyzing 102 National Hockey League prospects, a significant effect was found regarding reaction time and accuracy.<\/p>\n<p><strong>The takeaway: Previously concussed elite-level athletes may experience lasting neurological effects that are not generally detected through standard clinical assessments. <\/strong><\/p>\n<p><strong>Suspect a Possible Concussion? Here&#8217;s What You Should Do <\/strong><\/p>\n<p>Concussions are fairly common, affecting anywhere between 1.6 to 3.8 million Americans each year. Whether you play sports or have hit your head at work, here&#8217;s what you need to know:<\/p>\n<ol>\n<li><strong>Know the warning signs<\/strong> \u2014 If you have been hit in the head or suffered an injury, do not be left alone. Recognize warning signs, such as <strong>blurry vision, dizziness, vomiting, memory loss, slurred speech, numbness, headaches<\/strong>, etc.<\/li>\n<\/ol>\n<ol start=\"2\">\n<li><strong>Seek a professional opinion<\/strong> \u2014 There&#8217;s a range of tests available, including CT and MRI scans, as well as neurological tests. <strong>Seeking an accurate diagnosis<\/strong> is important, especially if you&#8217;re not sure what to do next.<\/li>\n<\/ol>\n<p><strong>Rest<\/strong> \u2014 You need to allow your brain to rest in order to effectively recover. That means, resting both physically and cognitively. Following your injury, don&#8217;t even read or watch TV \u2014<strong> truly rest your body and brain<\/strong>. If symptoms continue to persist (as discussed above), even if you have already seen the doctor, call your physician once again to ensure your safety.<\/p>\n<p><strong>References<\/strong><\/p>\n<p>https:\/\/www.scientificamerican.com\/article\/what-happens-to-the-brain\/ https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24322397 http:\/\/www.bu.edu\/cte\/about\/what-is-cte\/ http:\/\/www.cmaj.ca\/content\/early\/2016\/02\/08\/cmaj.150790 https:\/\/www.ucsf.edu\/news\/2016\/12\/405096\/alzheimers-and-concussion-related-cte-may-spread-brain-common-mechanism<br \/>\nhttp:\/\/www.brainline.org\/content\/2012\/06\/what-should-you-do-if-you-think-you-have-had-a-concussion.html<\/p>\n<p style=\"text-align: center;\">\r\n\t<section id=\"yikes-mailchimp-container-5\" class=\"yikes-mailchimp-container yikes-mailchimp-container-5 \">\r\n\t<section class=\"yikes-mailchimp-form-description yikes-mailchimp-form-description-5\">Subscribe &amp; keep up to date on Alzheimer&#039;s, Dementia &amp; more<\/section>\t\t\t<form id=\"knowledge-center-subscribe-5\" class=\"yikes-easy-mc-form yikes-easy-mc-form-5 yikes-mailchimp-form-inline  knowledgeCenterEmail\" method=\"POST\" data-attr-form-id=\"5\">\r\n\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t<label for=\"yikes-easy-mc-form-5-EMAIL\"  class=\"label-inline EMAIL-label yikes-mailchimp-field-required \">\r\n\r\n\t\t\t\t\t\t\t\t\t\t<!-- dictate label visibility -->\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"EMAIL-label\">\r\n\t\t\t\t\t\t\t\t\t\t\t\tEmail Address\t\t\t\t\t\t\t\t\t\t\t<\/span>\r\n\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\t\t<!-- Description Above -->\r\n\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\t\t<input id=\"yikes-easy-mc-form-5-EMAIL\"  name=\"EMAIL\"  placeholder=\"Enter your email address\"  class=\"yikes-easy-mc-email \"  required=\"required\" type=\"email\"  value=\"\">\r\n\r\n\t\t\t\t\t\t\t\t\t\t<!-- Description Below -->\r\n\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\t<\/label>\r\n\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t<!-- Honeypot Trap -->\r\n\t\t\t\t<input type=\"hidden\" name=\"yikes-mailchimp-honeypot\" id=\"yikes-mailchimp-honeypot-5\" value=\"\">\r\n\r\n\t\t\t\t<!-- List ID -->\r\n\t\t\t\t<input type=\"hidden\" name=\"yikes-mailchimp-associated-list-id\" id=\"yikes-mailchimp-associated-list-id-5\" value=\"9a39478864\">\r\n\r\n\t\t\t\t<!-- The form that is being submitted!
