My understanding of PTSD, in particular that caused by war time service or severe sexual assault, never goes away. PTSD is also very misunderstood by the general public. For many combat veterans their whole personality changes into a defensive roll, almost to the point of paranoia. Trust in others is severely eroded which may cause reclusiveness or in a few cases violent outbreaks.
My point is exercise may help, but there is no cure for PTSD. It’s there for life.
I have worked with severe PTSD in Veterans and trauma experiencers with near 100% resolution.
The key is to find the initial perceptual programming event that predisposed the person to PTSD. Often this happened in early childhood.
I have the advantage in that the stored traumatic memories are physical objects to my perception. The person need not say anything. They merely think of the trauma and the stored memory of the event becomes physical to me. There are several techniques using plasticity to reprogram the stored memory and remove the intense emotion attached to the memory.
This also works very well when working with victims of violent rape.
