If you didn't catch my interview on post-traumatic stress disorder last week, I urge you to give it a read. Long story short, the brain works in mysterious and sometimes nightmarish ways as a result of traumatic experiences.
This is abundantly obvious in two disparate but deeply heartbreaking cases:
* Tibetans call it srog-rlung, an imbalance of the "life-wind," but to Western doctors treating monks whose training in meditation could not block the flashbacks from when they were tortured by the Chinese as political prisoners, it had a more familiar name -- PTSD.
* Some Holocaust survivors who have been diagnosed with Alzheimer's Disease are found to be reliving their concentration camp experiences as though they're happening for the first time.Photograph by Mark Wilson/Boston Globe
