A link between video games (and not enough exercise), hippocampus, and PTSD
I read on the forum that some of the recruits mention how the night goggles remind them of the video games and became interested in the link between memories and PTSD. I began a search on the effects of adrenaline on the body.
Long term adrenaline effects from playing the games
or any other long term experiences we have which cause the body to produce adrenaline YET NOT ACTUALLY BE IN DANGER, may
damage the hippocampus. (part of the brain
responsible for memory storage). The damage is caused when the body doesn't work off the physical effects of adrenaline.
What increases adrenaline?

"Many
computer games have been shown to
simulate the types of
real world situations that cause it to be released into the human body, particularly first person shooters, sports games and popular multiplayer role games"
What is ADRENALINE?

"Though adrenaline can play a key role in the body's survival, it can also cause
detrimental effects over time...... it may cause the
hippocampus to shrink."
"In the past, people handled this naturally through fighting or other physical exertion, but in the modern world, high-stress
situations often arise
that involve little physical activity."
What is the HIPPOCAMPUS? *the part of the brain responsible for
encoding long term memory.

“Hippocampal shrinkage,” of all the terrible-sounding human ailments,
it common among PTSD patients."
"A damaged hippocampus causes weird things to happen,
it's like a damaged hard drive."
"One
much-cited 2002 study of twins showed that some people who wind up with
PTSD have smaller hippocampi to start with."
"A
soldier in combat needs quick memory feedback to know when he’s in trouble, and some
recent work suggests that a
hobbled hippocampus can blur danger response, leading the brain to notice more cues than necessary and causing the soldier, in effect, to freak out"
