Minor head injury is also dangerous

As suggested by a new study, a mild or moderate tremor may have a longer lasting effect than one might think.

By comparing brain imaging studies and thinking tests between healthy people and people with relatively mild shocks, researchers found that the recovery of thinking skills can take long time.

A mild shock may be caused by accidents such as a fall, a crash while traveling at a slow speed or being punched for the first time.

Initially, the results of memory and thinking tests of people with mild concussions were 25% lower than those of healthy people. However, one year after the concussion, while the results of people with or without concussion are the same, those with concussions in the brain still show brain damage in imaging diagnoses, with marks The clear effect of constantly breaking important brain cells.

Andrew Blamire, the lead author of the study and professor of magnetic resonance physics at Newcastle University in England, said the results are particularly important because 90% of all brain injuries are mild and moderate.

And Dr. Michael O'Brien, Director of the Sports Injury Center at Children's Hospital Boston, points out: 'People know about this very well - that people with poor grades in school, are physically poor and even poor in social issues - the fact that there are structural injuries have happened to them, even a year after the tremor ".

The study was published online July 16, 2014 in the May issue of the journal Neurology.

A concussion is a type of injury that occurs when the head is struck against an object, when an object strikes the head, or when the head is subjected to an unexpected force that is not caused by a direct hit. According to the American Academy of Neurology, there are about 2 to 4 million concussions from sports and entertainment every year in the United States. Most tremors recover completely.

O'Brien said that children are the main subject or affected by trauma because they are still developing, and they can easily suffer multiple injuries for years. In addition, the pressure shown on the field and in the classroom can cause injuries to recover slowly.

Experts have not yet answered the question of how brain damage affects thinking because while CT diagnostics and imaging diagnoses may show lesions in certain areas, it does not show signs. effect of diffuse injuries. Therefore, researchers have not been able to see a clear link between what they see from image studies and thought tests.

The problem is that the problem cannot be based solely on symptoms to know the whole cause and effect of tremors. O'Brien said: 'The level of symptoms is not always equivalent to the degree of injury'. That's not to mention other problems such as depression or low thyroid levels that may reflect like tremors.
