Mild TBI Causes Cognitive Impairments
Neuroscientists at Newcastle University in the U.K. have investigated the cognitive capacities of 44 people with mild TBI vs. 9 normal controls. They found that for a period of one year following their accident the mildly brain injured subjects performed 25% worse on memory and cognitive testing than the controls due to white matter brain damage confirmed through Tensor Diffusion MRI scans. Healing of brain injury was correlated with a return to normal memory and cognitive functioning. This was a small study, but it provides confirmatory evidence that so called “concussions” can have a significant affect on memory and thinking, and that such complaints are not just “made up” for litigation purposes.
