Although concussions are often " underestimated "by athletes, these can pose serious neurological hazards. Doctors define a concussion as a traumatically induced brain injury in which there is no identifiable anatomical lesion. A direct blow to the head can cause a concussion, but so can a blow to the neck or body that results in significant forces that are transmitted to the head. The symptoms of a concussion can be mild or severe, but are usually temporary. Seek medical attention immediately if you have a trauma to the head or neck.
The damage caused by a concussion is primarily functional rather than structural. After a concussion, the brain does not work exactly well, although it remains physically intact. While concussions are not uncommon, loss of consciousness is not a requirement to diagnose a concussion. However, losing consciousness after suffering a traumatic injury automatically means that you have suffered a concussion.
By definition, if you have suffered a concussion, you will experience some type of neurological change. According to an article published in the December 2010 issue of the "Journal of Physical Medicine and Rehabilitation," the symptoms of concussion can be classified into three categories: somatic, as headaches nausea, vomiting or balance problems, cognitive problems, such as memory loss, difficulty concentrating or feeling light-headed, and neurobehavioral, such as feeling anxious, depressed, tired or irritable
The vast majority of concussions are mild, and symptoms resolve within seven to 10 days in 80 to 90 percent of cases.In some cases, patients experience symptoms that persist in what is called post-concussion syndrome.These persistent symptoms can be very subtle, but tend to be more pronounced when the brain is under more pressure, for example, during physical exercise or during periods of Stress or insomnia Over time, these symptoms can take their toll on a person's daily life, which interferes with routines and functioning at work and at home.
The second impact syndrome, or SIS (for its acronym in English), is the most dangerous complication of a concussion. This occurs when the brain suffers a second injury, or other concussion, before it has completely healed from the first. Due to the chemical changes that occur with a concussion, the brain becomes especially vulnerable to injury.A second injury, even a relatively minor impact, during that period can result in sudden death. This is the most important reason why an athlete needs to completely heal from a concussion before he can be discharged to resume any activity that puts him at risk of major trauma to the head.
