Our question today comes from Lisa and Laura who ask:
We have a question about short term memory loss. Is it possible that someone in a traumatic car accident with a concussion but no other injuries would end up short term memory loss where they can't remember the week leading up to the accident?
"Concussion" and "Mild traumatic brain injury" is what's thrown around in the medical world. From here on out, I'm using different terms, because these aren't nearly as interesting.
After the trauma, many can have problems with dizziness, headaches, irritability, anxiety and attention problems. As for amnesia? It can happen in both directions.
Retrograde amnesia is when you cannot remember what happened before the trauma. Sometimes these memories can eventually be remembered.
Anterograde amnesia is when you cannot remember events that occur after the event, like the hospital visit or conversations just after the event. These memories usually can't be recalled later because the injured brain can't "encode" the new events into the memory.
The worse the head injury and the longer the time the person spends unconconcious, the longer the amount of memory lost. So for someone to forget an entire week prior to the event, that person must have hurt their head so badly they were unconscious for about 24 hours.
