Can head injuries lead to memory loss?

ANSWER

A fall, car accident, or other hard knock to the head can leave you unable to remember people or events. Even if the injury doesn't knock you unconscious, it can lead to memory loss.

Depending on how severe the hit to your head was, the memory issues might go away or be permanent.
