There have been many studies related to memory issues related to Post Traumatic Stress Disorder. This particular study, a literature review by Kirstin W. Samuelson entitled: “Post-traumatic stress disorder and declarative memory functioning: a review” looks at the association between “everyday memory problems with emotionally neutral material”.
Studies have shown that many PTSD patients complain of memory problems, aside from those symptoms that are part of the diagnostic criteria (intrusive thoughts, difficulty remembering parts of the trauma, etc.). This study focuses on declarative memory – that is memories that can be consciously recalled, like facts and knowledge. This type of memory can be broken down into two aspects: semantic memory which stores factual information and episodic memory which includes specific personal experiences.
The author notes “It should be emphasized that overall, decrements in memory performance due to PTSD are subtle, […] still, the findings are clinically meaningful when they represent a change in functioning before and after trauma”. She goes on to say that “the pattern of memory deficits reveal that PTSD most significantly impacts the initial acquisition and learning phases of memory, as opposed to the retention phase”.
In plain English this is a great big “duh!” to those of us with PTSD. We deal with this every day. We forget the simple things, we give up on school because learning seems so much harder than it used to be before…before our world changed. Things that once seemed a piece of cake are now complicated and hard to remember.
