I saw this advert on telly today and it made me think about people who have had traumatic memories and how horrible it must be to be scarred by it for the rest of your life until you're lucky enough to forget it.

I started researching about trauma and memory loss and came across this; it's interesting how your brain deals with these things to protect you, though its also horrific how it can haunt you.
How Trauma Affects Your Memory
Memory loss is a frustrating and sometimes scary experience, especially if the memory loss is caused by a traumatic event. Research shows that physical and emotional trauma can directly affect your memory. Some of this memory loss may be a temporary way to help you cope with the trauma, and some of this memory loss may be permanent due to a severe brain injury or severe psychological trauma.
Emotional Trauma and Memory Loss
Emotional or psychological trauma can also affect your memory. Memory loss is a natural survival skill and defense mechanism humans develop to protect themselves from psychological damage. Violence, sexual abuse and other emotionally traumatic events can lead to dissociative amnesia, which helps a person cope by allowing them to temporarily forget details of the event. A person will often suppress memories of a traumatic event until they are ready to handle them, which may never occur.
Emotional trauma can also lead to post-traumatic stress disorder, which can manifest itself in different ways including flashbacks of the event and intrusive, unwanted thoughts about the trauma.
