The Washington Post (2/28, Searing) reports, “Experiencing three or more concussions, even mild ones, can lead to cognitive problems decades later, according to research published in the Journal of Neurotrauma.” However, “just one moderate to severe concussion – or traumatic brain injury (TBI), in medical terms – was found to have a long-term impact on brain function, including but not limited to memory issues.” The study “found that cognitive problems were dose-dependent, meaning the effects on long-term cognitive performance increased as the number of TBIs grew – with thought-processing speed and working memory suffering.”
