I've been doing a lot of research into 'diagnosis' of PTSD & how actually a lot of people really have brain/central nervous system/neurological damage - very interesting & important! eg: Soldiers are often exposed to 'brain shear' from explosions etc AND nerve toxins/insecticides etc (crossover with Gulf War Syndrome) - these can cause very similar symptoms to PTSD (lots info on problems differentiating between Gulf War Syndome & PTSD). Then the person realises they have lost half their brain-power, can't do things that were easy before & gets accute anxiety/stress etc. ABI survivors (Aquired Brain Injury) ALL have bad problems with anxiety/sleep etc... seems that it could well be POLICY (both medical & military) to NOT do MRIs on everybody with weird brain/stress problems that could well be neurological in origin - funny that later on in the process, when they DO do an MRI, they find severe brain changes. It is of course cheaper & less financial liability for both medics AND military to 'diagnose' PTSD rather than brain damage! This brain damage can also apply to kids/anyone who has been battered/beaten/bashed & of course traffic accidents (including whiplash) can easily cause brain damage. Interestingly, there is a lot of research that shows some anaesthetic drugs cause 'PTSD-like symptoms' - and some of these drugs are neuro-toxic, this may have a bearing on 'anaesthetic awareness' survivors... Is there anyone out there doing GOOD research: eg: do MRIs on loads of soldiers straight after explosions/injury etc = SEE if brain damage... then of course PTSD can follow aswell: terror at not able to do/understand as before AND that the event (that was SURVIVED)that caused this terrible change, becomes yet MORE terrible in the person's mind. There is something called 'diagnostic overshadowing' : patients are labelled as purely 'psychiatric' cases, then a very high percentage (if docs BOTHER to refer for real investigations) actually have REAL physical/neurological damage, but the medics say it's 'imagined' - trouble is, we trust the medics & it's a rare & brave person who dares persist & NOT accept a shaky 'diagnosis' & fights (against all odds!) to find out the truth. Hmmmmm, wadda ya all think?
