Recently released information regarding evidence of a brain injury in an Army reservist responsible for a mass shooting in Maine has prompted caution from brain injury experts. Boston University researchers conducted an analysis of Robert Card's brain tissue, revealing signs of traumatic brain injury. The examination indicated degeneration in nerve fibers, inflammation, and small blood vessel injury.
Card, who had served as an instructor at an Army hand grenade training range, may have been exposed to repeated low-level blasts. However, it remains unclear whether this exposure caused his brain injury and what impact it had on his mental health leading up to the tragic incident on October 25 in Lewiston.
