An article in “Wired” from March 2012 entitled “The Forgetting Pill erases Painful Memories Forever”. describes an experimental therapy for eliminating negative memories to help patients struggling with Post Traumatic Stress Disorder (PTSD), as well as less severe conditions. The treatment involves giving patients the equivalent of blood pressure medication which only lasts 3 hours vs. full strength version of the medication which may last all day. Once the medication, which has a calming effect, kicks in, the patients are then asked to recall the traumatic or negative memory in as much detail as possible.
According to the article, every time we remember or relive an event, we rewrite it to our memory along with the emotional state we are in at the time we recant it. Because the blood pressure medication lessens general excitement, the memory is re-experienced and “rewritten” to the mind from a more objective perspective with less emotional attachment to the memory of the event.
What I found intriguing about this article was that the treatment is in many ways similar to the technique of Vipassana meditation I study, where practitioners are asked to sit motionless with eyes closed and methodically pay close attention to sensations on the body. While doing so, they are instructed to stay focused and not to react with craving or aversion to these sensations on the body (no matter how pleasant or unpleasant) and to simply observe them with compassion and equanimity. The sensations on the body are, according to the teaching, tied directly with emotions and memories in the subconscious. By acknowledging the sensations we are tapping into subconscious memories and re-experiencing them in a direct way. The word ‘recognize’ literally means to re-think. By remaining equanimous, or accepting the truth about how we feel about our experiences at the deepest level, we become free of them.
If they are not accepted by the mind and integrated in to the life-experience, over time and through repetition, these layers of emotions associated with the initial experience intensify, as do the physiological and biochemical reactions to the memory. If negative, these emotions can cause mental and physical stress and tension in the form of a fight or flight response. If positive, the emotions can result in clinging or craving, resulting in an addiction to the experience. More specifically an addiction to the biochemicals is produced by the emotions associated with the memory of the experience.
The danger is that the biochemicals, regardless of whether or not the subject sees the memory as good or bad, create a craving for more of the chemical, which is why anger or depression can sometimes spiral out of control. The angrier we get, the more we tend to generate even greater anger, feeding back on itself into an upward spiral of fury. Similarly downward spirals of depression create an inescapable feedback loop of angst and misery.
In either situation there is a physiological response to the emotion reaction: the secretion of biochemicals resulting in things such as an increase of adrenaline, vascular and muscle constrictions, and/or an increase in blood pressure, to name a few. This can manifest in the form of back pain, stomach problems, migraines, insomnia, heart disease, and even cancer. Over time the increasing physical and biochemical changes in the body can and do make us sick, yet they originate in the mind. In this way, meditation for anxiety has similar benefits to the drug-based therapy.
Whether under the influence of a calming drug, as described in the Wired article, or under the influence of a disciplined mind through meditation, there is a lessened reaction to the experience by not reinforcing the story in an environment of strong emotions. Through repeated exposure to the memories under “safe” environments, the self-generated and self-perpetuated emotional level is diminished, as well as the physiological and biochemical responses.
The main difference between this new therapy and sensory-based meditation is that with Vipassana meditation at least, concentrating on the conscious memories and reliving experiences during meditation are discouraged. One in instructed to only pay attention to sensations directly on the body and keep focused on that activity, since sensations are tied to the more important memories and emotions residing in the subconscious.
While the application of drugs in conjunction with talking about the memories could perhaps tap in to the subconscious to some degree, results of the therapy described in the Wired article are inconclusive. My sense is it will have limited success with victims of PTSD or other forms of anxiety, since the issues are only being dealt with closer to the conscious level.
In certain cases, there is certainly no substitute for modern medicine, especially where symptoms need to be diminished in order for the person to heal. Ultimately though, we are our own masters and need to take control of how our mind reacts to the past, present and future for our own health and benefit and those around us.
