Now more than ever we are aware of the impact of post-traumatic stress disorder (PTSD) on veterans returning from the front lines of wars in the Middle East, raging for the last ten years. These wounded warriors often respond poorly to traditional treatment with drugs, aimed at adjusting levels of brain neurotransmitters, which in part mediate the abnormal response to stress.
PTSD is characterized by repeated re-experience of traumatic events; avoidance symptoms, including reluctance to think or talk about the trauma; and excessive arousal symptoms, including poor sleep and poor concentration.
What is the biologic basis of this disorder? Though all of the puzzle pieces have not yet been put together, we do know that certain parts of the brain responsible for explicit memory (i.e., the verbal memory of the event) and emotional reaction do not function normally in people afflicted with PTSD:
1. The gateway of memory, the hippocampus, located near the undersurface of the brain, is reduced in size in many PTSD patients, apparently because of the negative effect of stress hormones on the nerve cells that make up this structure. The result is memory impairment and amnesia for some events.
2. A neighboring structure, the amygdala, is abnormally activated in PTSD. The amygdala infuses memories with strong emotion, and its excessive activity can trigger anger and rage reactions.
3. The prefrontal cortex, the seat of judgment and planning, thought to act as a counterbalance to the impulsive amygdala, is also negatively affected in PTSD.
PTSD has traditionally been treated like other anxiety disorders characterized by episodic flare-ups, which are incapacitating. Drugs aimed at treating both anxiety and depression are utilized, as are behavioral therapies, all with limited success.
The recent pilot study showing a 50% reduction in PTSD symptoms in veterans practicing Transcendental Meditation is welcome news . . . .
Global Good News will continue featuring Dr Kaplan's post, which looks more deeply into the recently published research study on Transcendental Meditation and PTSD, and discusses beneficial EEG changes during the technique. It also includes a video post of an Iraq war veteran describing the relief from PTSD symptoms that he found soon after learning Transcendental Meditation.
