Evidence from clinical studies found that high school-aged athletes had slower recoveries from concussion as measured by neuropsychological tests than college-aged ones and adults. PCS is rare in young children. Risk factors
A wide range of factors have been identified as being predictive of PCS, including low socioeconomic status, previous mTBI, a serious associated injury, headaches, an ongoing court case, age and female sex. Being older than 40 and being female have also been identified as being predictive of a diagnosis of PCS, and women tend to report more severe symptoms. In addition, the development of PCS can be predicted by having a history of alcohol use disorder, low cognitive abilities before the injury, a personality disorder, or a medical illness not related to the injury. PCS is also more prevalent in people with a history of psychiatric conditions such as clinical depression or anxiety before the injury.Mild brain injury-related factors that increase the risk for persisting post-concussion symptoms include an injury associated with acute headache, dizziness, or nausea; an acute Glasgow Coma Score of 13 or 14; and having another head injury before recovering from the first. The risk for developing PCS also appears to be increased in people who have traumatic memories of the injury or expect to be disabled by the injury. History
The symptoms that occur after a concussion have been described in various reports and writings for hundreds of years.
Most of them come with the complaints of "drops" and become extremely anxious about it and see it as loss of "male power". It is often related with obsessive ruminations and somatoform symptoms. Others see it as a distinct clinical entity which is less culture-bound than these critics assert, and describe it as one form of a syndrome of "semen-loss anxiety" which also occurs in other Eastern cultures as jiryan and shen-kuei, as well as in Western cultures. Chlamydia infection might also be related to it because of similar symptoms in case of infection of the urethra (urethritis), which is usually symptomatic, causing a white discharge from the penis with or without pain on urinating (dysuria).
