Biomedical Ethics Quotes

Meanwhile, scientists are studying certain drugs that may erase traumatic memories that continue to haunt and disturb us. In 2009, Dutch scientists, led by Dr. Merel Kindt, announced that they had found new uses for an old drug called propranolol, which could act like a “miracle” drug to ease the pain associated with traumatic memories. The drug did not induce amnesia that begins at a specific point in time, but it did make the pain more manageable—and in just three days, the study claimed. The discovery caused a flurry of headlines, in light of the thousands of victims who suffer from PTSD (post-traumatic stress disorder). Everyone from war veterans to victims of sexual abuse and horrific accidents could apparently find relief from their symptoms. But it also seemed to fly in the face of brain research, which shows that long-term memories are encoded not electrically, but at the level of protein molecules. Recent experiments, however, suggest that recalling memories requires both the retrieval and then the reassembly of the memory, so that the protein structure might actually be rearranged in the process. In other words, recalling a memory actually changes it. This may be the reason why the drug works: propranolol is known to interfere with adrenaline absorption, a key in creating the long-lasting, vivid memories that often result from traumatic events. “Propranolol sits on that nerve cell and blocks it. So adrenaline can be present, but it can’t do its job,” says Dr. James McGaugh of the University of California at Irvine. In other words, without adrenaline, the memory fades. Controlled tests done on individuals with traumatic memories showed very promising results. But the drug hit a brick wall when it came to the ethics of erasing memory. Some ethicists did not dispute its effectiveness, but they frowned on the very idea of a forgetfulness drug, since memories are there for a purpose: to teach us the lessons of life. Even unpleasant memories, they said, serve some larger purpose. The drug got a thumbs-down from the President’s Council on Bioethics. Its report concluded that “dulling our memory of terrible things [would] make us too comfortable with the world, unmoved by suffering, wrongdoing, or cruelty.… Can we become numb to life’s sharpest sorrows without also becoming numb to its greatest joys?” Dr. David Magus of Stanford University’s Center for Biomedical Ethics says, “Our breakups, our relationships, as painful as they are, we learn from some of those painful experiences. They make us better people.” Others disagree. Dr. Roger Pitman of Harvard University says that if a doctor encounters an accident victim who is in intense pain, “should we deprive them of morphine because we might be taking away the full emotional experience? Who would ever argue with that? Why should psychiatry be different? I think that somehow behind this argument lurks the notion that mental disorders are not the same as physical disorders.

We define empirical research in biomedical ethics as the application of research methods in the social sciences to the direct examination of issues in biomedical ethics
