One of the criteria for the PTSD diagnosis or at least are not preoccupied with specific memories of their abuse, but they continue to behave as if they were still in danger.

DSM largely lacks what in the world of science is known as “reliability”—the ability to produce consistent, replicable results. In other words, it lacks scientific validity.
-
Long after a traumatic experience is over, it may be reactivated at the slightest hint of danger and mobilize disturbed brain circuits and secrete massive amounts of stress hormones. This precipitates unpleasant emotions intense physical sensations, and impulsive and aggressive actions. These posttraumatic reactions feel incomprehensible and overwhelming. Feeling out of control, survivors of trauma often begin to fear that they are damaged to the core and beyond redemption.

Our bodies are the texts that carry the memories and therefore remembering is no less than reincarnation.
-
Symptoms of PTSD often include statements like “I feel dead inside,” “I will never be able to feel normal emotions again,” “I have permanently changed for the worse,” “I feel like an object, not like a person,” “I have no future,” and “I feel like I don’t know myself anymore."

The most important job of the brain is to ensure our survival, even under the most miserable conditions. Everything else is secondary. In order to do that, brains need to: (1) generate internal signals that register what our bodies need, such as food, rest, protection, sex, and shelter; (2) create a map of the world to point us where to go to satisfy those needs; (3) generate the necessary energy and actions to get us there; (4) warn us of dangers and opportunities along the way; and (5) adjust our actions based on the requirements of the moment.

Because most of these patients suffered from alexithymia, it was not easy for them to report their response to the treatments. But their actions spoke for them: They consistently showed up on time for their appointments, even if they had to drive through snowstorms. None of them dropped out, and at the end of the full twenty sessions, we could document significant improvements not only in their PTSD scores, but also in their interpersonal comfort, emotional balance, and self-awareness. They were less frantic, they slept better, and they felt calmer and more focused. In any case, self-reports can be unreliable; objective changes in behavior are much better indicators of how well treatment works.

Memories of traumatic experiences may not be primarily retrieved as narratives. Our own and others’ research has suggested that PTSD traumatized people’s difficulties with putting memories into words are reflected in actual changes in brain activity.

We can speak of trauma when that system fails: when you beg for your life, but the assailant ignores your pleas; when you are a terrified child lying in bed, hearing your mother scream as her boyfriend beats her up; when you see your buddy trapped under a piece of metal that you’re not strong enough to lift; when you want to push away the priest who is abusing you, but you’re afraid you’ll be punished. Immobilization is at the root of most traumas. When that occurs the DVC is likely to take over: Your heart slows down, your breathing becomes shallow, and, zombielike, you lose touch with yourself and your surroundings. You dissociate, faint and collapse.

The great challenge is finding ways to reset their physiology, so that their survival mechanisms stop working against them.

I decided to ask eight Vietnam combat veterans if they would be willing to take a standard pain test while they watched scenes from a number of movies. The first clip we showed was from Oliver Stone’s graphically violent Platoon (1986), and while it ran we measured how long the veterans could keep their right hands in a bucket of ice water. We then repeated this process with a peaceful (and long-forgotten) movie clip. Seven of the eight veterans kept their hands in the painfully cold water 30 percent longer during Platoon. We then calculated that the amount of analgesia produced by watching fifteen minutes of a combat movie was equivalent to that produced by being injected with eight milligrams of morphine, about the same dose a person would receive in an emergency room for crushing chest pain.

Modern neuroscience solidly supports Freud’s notion that many of our conscious thoughts are complex rationalizations for the flood of instincts, reflexes, motives, and deep-seated memories that emanate from the unconscious.

The disappearance of medial prefrontal activation could explain why so many traumatized people lose their sense of purpose and direction. I used to be surprised by how often my patients asked me for advice about the most ordinary things, and then by how rarely they followed it. Now I understood that their relationship with their own inner reality was impaired. How could they make decisions, or put any plan into action, if they couldn't define what they wanted or, to be more precise, what the sensations in their bodies, the basis of all emotions, were trying to tell them?
-
The foreword to the landmark 1980 DSM-III was appropriately modest and acknowledged that this diagnostic system was imprecise—so imprecise that it never should be used for forensic or insurance purposes. As we will see, that modesty was tragically short-lived.
-
Terror increases the need for attachment, even if the source of comfort is also the source of terror.
-
In patients with histories of incest, the proportion of RA cells that are ready to pounce is larger than normal. This makes the immune system oversensitive to threat, so that it is prone to mount a defense when none is needed, even when this means attacking the body’s own cells.

Chronic abuse and neglect in childhood interfere with the proper wiring of sensory-integration systems. In some cases this results in learning disabilities, which include faulty connections between the auditory and word-processing systems, and poor hand-eye coordination. As long as they are frozen or explosive, it is difficult to see how much trouble the adolescents in our residential treatment programs have processing day-to-day information, but once their behavioral problems have been successfully treated, their learning disabilities often become manifest. Even if these traumatized kids could sit still and pay attention, many of them would still be handicapped by their poor learning skills.
-
Trauma devastates the social-engagement system and interferes with cooperation, nurturing, and the ability to function as a productive member of the clan. In this book we have seen how many mental health problems, from drug addiction to self-injurious behavior, start off as attempts to cope with emotions that became unbearable because of a lack of adequate human contact and support.
-
Even traumatized patients who are making real contributions in teaching, business, medicine, or the arts and who are successfully raising their children expend a lot more energy on the everyday tasks of living than do ordinary mortals.
-
Noticing our annoyance, nervousness, or anxiety immediately helps us shift our perspective and opens up new options other than our automatic, habitual reactions.
-
Public story and inner experience finally met.
-
The frontal lobes allow us to plan and reflect, to imagine and play out future scenarios.
-
People who cannot comfortably notice what is going on inside become vulnerable to respond to any sensory shift either by shutting down or by going into a panic—they develop a fear of fear itself.

My colleague Rachel Yehuda studied rates of PTSD in adult New Yorkers who had been assaulted or rapes. Those whose mothers were Holocaust survivors with PTSD had a significantly higher rate of developing serious psychological problems after these traumatic experiences. The most reasonable explanation is that their upbringing had left them with a vulnerable physiology, making it difficult for them to regain their equilibrium after being violated. Yehuda found a similar vulnerability in the children of pregnant women who were in the World Trade Center that fatal day in 2001. Similarly, the reactions of children to painful events are largely determined by how calm or stressed their parents are.
