Your thinking and memory skills may take a hit decades after recovering from a concussion, a new study indicates. Scientists who studied male twins, from an average age of 67, found that earlier concussions were tied to lower scores on tests of thinking and memory. These men also had a more rapid decline in their cognitive skills — skills needed for reasoning and the acquisition of knowledge. “It is concerning and, honestly, since previous studies had not been able to capture the cognitive decline, it was not something I really was expecting to see,” said study author Marianne Chanti-Ketterl, a gerontologist at Duke University Medical Center in Durham, N.C. “But it is also promising because it’s something that we can intervene on.” Studying identical twins makes sense because they share the same genes and many of the same early life exposures. In this research, one person from each pair had sustained a traumatic brain injury (TBI) during their lifetime and the other hadn’t been injured. This study worked with data from nearly 7,200 white, male World War II veterans who were twins. The men took a thinking skills test when the study began, at age 67 on average. They took the tests three more times over 12 years. Those with a history of concussion had the brain injury 34 years earlier on average. Participants started… read on > read on >
