The WHO mental health survey shows that approximately 70 percent of all people experience a trauma, such as the loss of a loved one, a life-altering injury, or direct exposure to violence. All of these triggers lead to a higher risk of post-traumatic stress disorder, PTSD. The available therapies have evolved to handle the spectrum of responses and associated conditions, but there is more to learn about their processes and the symptoms they treat.
Beta-blockers are blood pressure medications that cause the heart to beat with less force. Researchers discovered was that these same drugs can help some people with PTSD by reducing anxiety, a common symptom, and even dampening the fear response associated with certain memories. Because these beta-blockers can pass through the blood-brain barrier, doctors believe they inhibit the synthesis of certain proteins during those reexperienced fear memories, which causes partial memory erasure.
