The most hopeful and effective treatments for trauma use different pathways to reach the right brain, where childhood trauma is stored. Sadly TF-CBT is the most available kind of therapy, but it is generally not that useful for healing childhood trauma. In the case of my CASA youth, she felt "unhelpable" after several years of CBT did not help.
When your brain is programmed in Fight/Flight/Freeze patterns that arise from particular stimuli (triggers), it's hard to "think" your way into this pattern and break it by force of will. For a shock trauma that happens at an older age TF CBT may be effective, but for developmental (early) trauma, it is not.
The best results come from:
1. Neurofeedback: There are a variety of NF systems that require a diagnosis and a specific plan of use-- these systems are dependent on who the practitioner is and how experienced and skillful they are, which can be hard to assess. However, there is one system (Neuroptimal) that is "one size fits all" and focuses on Central Nervous System arousal and coherence. It trains the person for a calm CNS by giving them interruptions in the music they are listening to when their CNS is over- or under-active, or out of synch. This is one-size-fits-all training, so diagnosis is not a concern. This is the one my CASA youth did, and it was incredibly helpful to her. (Miracle-level helpful!) 20 sessions = 10 hours of clinical time, and her anxiety and depression essentially remitted. (If you use directed NF, make sure the therapist is VERY trained (~PhD) and experienced in the use of the machinery and in diagnosis.) The biggest advantage was that 1. it was FAST, 2. The client's OWN BRAIN solves it's own firing problems, when it is finally given feedback about what it is doing that's awry. This is extremely empowering, especially for a person who feels broken or flawed. Non verbal, so there is no re-traumatization.
2. Body-Based systems of "talk" therapy: NARM (Laurence Heller), Sensorimotor Psychotherapy (Pat Ogden), Somatic Experiencing (Peter Levine). These therapies basically bring the client back to the sensations of, and awareness of, their bodies. The focus stays on the body and what sensations it is experiencing. These systems help the client learn to feel, tolerate, and name emotions and notice them as physical feelings that move, morph, change and resolve if the client is able to let that physical process take place. These therapies hook up R and L brain through experiencing & re-hooking-up-to the sensations of the body (where trauma is stored).
3. EMDR. Also well validated for helping the right brain reprocess information that is 'stuck' due to trauma by mimicking REM sleep.
Be warned that there are a lot of posers in trauma therapy. There are alot of people who took one seminar and bill themselves as experts, or who use their own spin on a therapy that may render it very different or ineffective. You need to make sure you are dealing with an experienced, skilled practitioner who has the requisite accreditation.
