Epidemiology: Concussion is a leading public health problem affecting mostly young people (peak prevalence 0-4 years and 15-24 years). The number of young people who incur concussions is enormous. The general incidence of TBI in developed countries is frequently stated to be 200 per 100,000 populations at risk per year. This estimate typically includes only patients admitted to hospitals resulting in underestimation of the frequency of mild TBI and overestimation of the proportion of more severe TBI. But looking at the number of mild TBI in sports astonishing numbers are presented in literature. Only in sports there is an estimated 1.6 to 3.8 million sport-related concussions each year in the United States. In professional soccer, 2 out of 11 players are concussed every season, the same numbers account for American football. Research showed us that out of those millions of concussions annually, 15% of the concussed people will develop post-concussion syndrome or PCS. The movie ��?concussion��? featuring Will Smith made the problem clear to the general public. Post-concussion Syndrome: Post-concussion syndrome, or PCS, is a set of symptoms that may continue for weeks, months, or a year or more after a concussion. The condition is associated with a wide range of symptoms: pain sensations such as headache; energy loss and being easily fatigued after physical or cognitive exercises; cognitive impairments, such as difficulty concentrating, memory loss, slowing down of information processing, difficulties in initiating and sustaining cognitive processes (problems with ��?energizing��?); and emotional changes; frustration, sadness and irritability. Why some people do and some do not develop PCS after commotio cerebri has both biological and psychological causes. Studies using positron emission tomography have linked PCS to a reduction in glucose use by the brain. Changes in cerebral blood flow have also been observed as long as three years after a concussion in studies using single photon emission computed tomography (SPECT). At least one study with functional magnetic resonance imaging (fMRI) has shown differences in brain function during tasks involving memory after MTBI, although they did not examine PCS specifically. Additional studies have shown, using various MRI techniques (such as diffuse tensor imaging (DTI) MRI), that individuals with PCS have various abnormalities in their brain structure. Similar findings have recently been reported in soldiers with blast-induced mTBI/PCS. Psychological causes for continuation of PCS complaints are psychological stressors in different life domains like pending litigation, chronic stress, attachment disorders, perfectionism, anxiety and depression. Treatment: Physicians refer about 40% for psychological consultation. A review of controlled treatment outcome studies conducted over the past 2 decades in Scandinavia, Great Britain, Canada, and the United States suggests that early single session treatment can prevent the syndrome. Treatment approaches depend on the clinician��?s ability to differentiate among the various conditions associated with PCS. Early education (insight in complaints after MTBI), lifestyle information, cognitive behavioral therapy, and aerobic exercise therapy have shown efficacy in certain patients.
