Mild head injury is also often referred to as concussion, minor head injury or mild traumatic brain injury (mTBI). Regardless of the terminology used, the occurrence of a head injury in these cases causes the brain to shake back and forth inside the skull, causing mild damage.
Mild head injury is commonly caused by falls, road crashes, assaults and sports accidents. While most mild head injuries result in no long-term damage to the brain, it can cause temporary disruption to brain function that can last for at least a number of weeks.
This study is a long-term study to look at retired elite men and women athletes (who had a high risk of concussion during their sporting careers) and compare them to similarly aged controls with no history of TBI. The overall aim is to see whether a history of head injury makes individuals more at risk of Alzheimer’s disease, Parkinson’s disease, motor neuron disease or other brain problems.
