I would not be surprised if the corrolation between PTSD and dissociative issues rise.. my reasoning is because the DSM 5 has added a dissociative subset in with the diagnostic criteria for PTSD, which means dissociative amnesia and other dissociative symptoms are going to be looked at when a treatment provider is evaluating whether they needs to specify ....with dissociative issues or not when diagnosing PTSD now.

is dissociative amnesia over diagnosed...my opinion no why because its only been the last maybe 10 years or so that american treatment providers understood what dissociation is and how it can affect people. before it was a recognized disorder they couldnt very well diagnose it could that. sure it could get misdiagnosed as other things but before the DSM IV TR there was no standards for diagnosing it. since the DSM has recognized the disorder of course there was a rise in diagnosing it. and sure theres probably people some where who dont really have it but have read about it and "showed" "presented" to their treatment providers as being dissociative amnesia. but that happens with everything else in life too. over all I think american treatment providers are doing great with their diagnosing/labeling dissociative amnesia.
