Subconcussive is a medical term used to describe the impact of a head injury that does not cause a concussion but may still result in brain damage over time. Some synonyms for subconcussive include mild traumatic brain injury, minor head trauma, and latent brain injury. There are many different ways that subconcussive injuries can occur, such as from repetitive head impacts in sports or from exposure to explosion blasts in military combat. It is important to recognize the seriousness of subconcussive injuries, even if they do not result in immediate symptoms, as they can still lead to long-term cognitive and behavioral problems.
