here in the USA the definition of Amnesia is loss of memory, not loss of time. here loss of time can mean all kinds of things like not paying attention to the time when doing something, I know many people who lose time and they do not have any mental disorders.

here loss of time is when someone has a chunk of time (minutes, hours days weeks months that pass ) that can not be accounted for or a chunk of time in which they did not do their job.

example a friend and I were talking on the phone and before we knew it we had been on the phone for half an hour. it didnt seem like a half hour but the clock said a half hour had passed while we were talking.

another example of time loss. last winter when i became ill I lost time with my job, meaning I did not work for a few days while I was ill.

here in my location amnesia is anything that a person can not remember due to physical or emotional reasons...

example while camping one time I got hit in the head. i ended up with a concussion, for a couple hours I could not remember anything,

another example when a friend of mine was in an accident they had amnesia from getting knocked unconscious.

another example many sports figures end up with head related injuries and amnesia from the sports injuries.

in my location the definition of the word true is anything that is not faked. the only way amnesia and dissociative amnesia is not true is if the person is faking they have the physical injury or faking they have a mental disorder which they dont have.

example not too long ago CNN did some reports on a woman that had scammed people out of money by faking she had cancer. it was not true that she had cancer..

my location the difference between Amnesia and dissociative amnesia is that Amnesia is caused by physical means (a brain injury or getting hit in the head), whereas dissociative amnesia is caused by mental means (stress, trauma caused the person to mentally block out the memory of that stressful or traumatic event through the use of dissociation.)

some people with dissociative amnesia only block out one event which lasts only a matter of minutes....example my wife has dissociative amnesia surrounding choking on a meat bone. her family tells the story and she has no memory of those few minutes it took for her parents to dislodge that bone. it was only a matter of a few minutes but to her it was so traumatizing that she does not remember it.

here in my location with DID...the person doing the dissociating doesnt have that memory but the alter that takes over to handle that event does...

example I did not remember getting lost in the mine shaft (I dissociated) and another alter took over. since the alter was the one in control that alter had the memory of getting lost in the mine shaft. after my alters all integrated with me I had that memory back again.
