How much would you remember if you were to have retrograde amnesia?

i know that retrograde amnesia is the inability to recall events before the traumatic accident, but does that mean the person won't know worldly things? like how to count money, or how to shop, or designers and brands?How much would you remember if you were to have retrograde amnesia?
When you experience something, it gets stored in short-term memory. From there it is move to middle-term memory and then to long-term memory. (There are actually finer distinctions than this, but this simplified model is enough to explain this.) If you experience retrograde amnesia because of a head injury, seizure, or medication, that process gets interrupted. Whatever was in the pathway toward long-term memory gets lost before it can be stored into long term memory, but whatever is already in long-term memory is still there.



So, depending upon how severe it is, a person will not remember several hours before or even the whole day up to the event. Sleep is involved in the process of storing long-term memories, so retrograde amnesia rarely goes back further than the last time you slept. But everything before that point will be remembered normally.



So, unless you learned how to shop an hour before you smashed your head into something, you will still remember how to shop.
