There is a recent book for professionals, that most libraries would have.
Cognitive-Behavior Therapy for Severe Mental Illness [www.appi.org
It even has a DVD, with role-play.
In that book, it shows how there is scientific evidence in several studies, (page 6-7) that an increase in life STRESS occurs right before hospitalization for people with bipolar and mania, and also for people WITHOUT previous psychiatric disorders.
So its the extreme STRESS of these LGAT seminars, and everything that goes on with them, including triggering traumatic memories and PTSD, sleep deprivation, food deprivation, and dozens of other things ALL AT ONCE.
All of that massive stress for many days, is triggering severe mental breakdowns in people, which can lead to hospitalization.
They know this of course, which is why they have their release of liability, they know the seminar triggers hospitalizations and suicide attempts and death by suicide. Not only for people with previous mental health issues, but also for people who have never had a mental illness.
That is why they try to protect themselves.
Just triggering PTSD by these amateurs, hacks and quacks, would certainly lead to cases of suicide. PTSD is lethal, and triggering it like they do in these seminars, then just leaving people with untrained people, is lethal.
Once the PTSD pain gets triggered, it doesn't stop, and that leads to many many suicides, that happen rapidly.
They know all this of course, its in the disclaimers.
Their philosophy is, pay in advance, welcome to The School of Hard Knocks, and the malpractice we do to you, is your fault.
