Head injuries are often fatal, or of sufficient severity to require the hospitalization of victims. But there is a large group of people who sustain head injuries which can go undetected through ordinary medical examination. These are the people who seemingly recover from their injuries but still suffer subtle intellectual and behavioural effects that may seriously impair their ability to work and interact normally with other people. They are the victims of what experts call a “silent epidemic”. Some never lost consciousness and others never even suffered a direct blow to the head, yet brain damage occurred.
