The long-run consequences for these patients may be severe secondary complications including cerebral infarction with serious consequences for the patient’s social life. In addition to this, it was recently found that many traumatic brain injuries are, in the long run, complicated by dementia.
In 2013, a research study led by Hans von Holst was published in the Journal of Neurotrauma, (länk till publikationen). The purpose of the study was to analyze the speed and energy required to break the hydrogen bond in protein structures. And the hypothesis is that this new knowledge can help define why and when a concussion occurs. We do know that broken proteins destroy the function of the proteins in the body, which increases the risk of long-term complications. The discovery was that the hydrogen bonds are maintained up to a speed of about 4 m/s (14,4 km/h) but are broken from about 5-6 m/sec (18-21,6 km/h) and up.
In addition, it was demonstrated that hydrogen bonds are also broken on the opposite side of the brain, which was a completely new discovery within the field of research.
