Memory loss is typically divided into three main categories:
Post-traumatic amnesia – This refers to memory loss immediately after a traumatic event. You may simply be confused about some of what happened. Your memories may come back soon after the crash.
Anterograde amnesia – This is a memory issue that prevents you from forming new memories. Some victims may say it feels like they blacked out right after the crash.
Retrograde amnesia – This is a condition that causes you to forget things that happened before the accident. You might not remember significant events in your life.
