Anxiety disorders and symptoms can often be effectively treated with benzodiazepine medications. It is known that animals exposed to stress exhibit a decrease in benzodiazepine receptor binding in the frontal cortex. The paper Decreased Benzodiazepine Receptor Binding in Prefrontal Cortex in Combat-Related Posttraumatic Stress Disorder (Amer. J. of Psychiatry, 2000: 11201126) described the first study of benzodiazepine receptor binding in individuals suffering from PTSD. The accompanying data on a receptor binding measure (adjusted distribution volume) was read from a graph in the paper. PTSD: 10, 20, 25, 28, 31, 35, 37, 38, 38, 39, 39, 42, 46 Healthy: 23, 39, 40, 41, 43, 47, 51, 58, 63, 66, 67, 69, 72 Use various methods from this chapter to describe and summarize the data.
