“Mild” Brain Injuries

Apparently, there’s no such thing as a “mild” brain injury.

Researchers have shown that exposure to shock waves can cause temporary and permanent decline in brain function, even if there are no obvious signs of damage such as bleeding on the brain and the victim shows no signs of concussion.

Unlike severe or moderate bTBIs, a mild bTBI shows no overt brain injury, such as bleeding, hematomas or bruising, and people with a mild bTBI do not lose consciousness or show concussion symptoms. Nevertheless, these injuries can eventually lead to cognitive impairment, loss of attentional function, drug addiction, and anxiety or depressive disorders.(1)

The bTBI is “blast induced traumatic brain injury.” However, the results raise questions about other firms of shocks to the brain, and ties into other research results regarding shaking of the cortex, discussed in my prior post.

People who have injuries may not show overt signs and may not be able to collect damages in court. In fact, the impacts may not be felt for years, until well after current statutes of limitations take effect. However, the damage can affect how you think, depression, risky behavior, and quality of life.
