Psychopharmacology and memory.

Psychotropic and other drugs can alter brain mechanisms regulating the formation, storage, and retrieval of different types of memory. These include "off label" uses of existing drugs and new drugs designed specifically to target the neural bases of memory. This paper discusses the use of beta-adrenergic antagonists to prevent or erase non-conscious pathological emotional memories in the amygdala. It also discusses the use of novel psychopharmacological agents to enhance long term semantic and short term working memory by altering storage and retrieval mechanisms in the hippocampus and prefrontal cortex. Although intervention in the brain to alter memory as therapy or enhancement holds considerable promise, the long term effects of experimental drugs on the brain and memory are not known. More studies are needed to adequately assess the potential benefits and risks of these interventions.

Do the sick have a right to cadaveric organs?

One way of increasing the supply of organs for transplantation is to adopt a policy giving the sick a right to cadaveric organs. Such a right would entail the coercive transfer of organs from the dead without their previous consent. Because this policy would violate individual autonomy and the special relation between humans and their bodies, it would be morally unjustifiable. Although a rights-based non-consensual model of salvaging cadaveric organs would be medically desirable, a communitarian-based consensual model would be a morally justifiable alternative way of addressing the problem of organ scarcity.

Are doctors altruistic?

There is a growing belief in the US that medicine is an altruistic profession, and that physicians display altruism in their daily work. We argue that one of the most fundamental features of medical professionalism is a fiduciary responsibility to patients, which implies a duty or obligation to act in patients' best medical interests. The term that best captures this sense of obligation is "beneficence", which contrasts with "altruism" because the latter act is supererogatory and is beyond obligation. On the other hand, we offer several examples in which patients act altruistically. If it is patients and not the doctors who are altruistic, then the patients are the gift-bearers and to that extent doctors owe them gratitude and respect for their many contributions to medicine. Recognising this might help us better understand the moral significance of the doctor-patient relationship in modern medicine.

Tracing the soul: medical decisions at the margins of life.

Most religious traditions hold that what makes one a person is the possession of a soul and that this gives one moral status. This status in turn gives persons interests and rights that delimit the set of actions that are permitted to be done to them. In this paper, I identify the soul with the capacity for consciousness and mental life and examine the ethical aspects of medical decision-making at the beginning and end of life in cases of patients who either never have had or have lost this capacity. I argue that, although these patients may lack moral status, they nonetheless have moral value as human organisms and forms of God-given biological life. In particular, I explore what this value entails about the permissibility of withholding or withdrawing life-sustaining treatment and of harvesting viable organs from patients with no higher-brain function.

Responsibility, alcoholism, and liver transplantation.

Many believe that it is morally wrong to give lower priority for a liver transplant to alcoholics with end-stage liver disease than to patients whose disease is not alcohol-related. Presumably, alcoholism is a disease that results from factors beyond one's control and therefore one cannot be causally or morally responsible for alcoholism or the liver failure that results from it. Moreover, giving lower priority to alcoholics unfairly singles them out for the moral vice of heavy drinking. I argue that the etiology of alcoholism may involve enough control for the alcoholic to be responsible for his condition and accordingly have a weaker claim to receive a new liver than someone who acquires the disease through no fault of his own. In addition, I show why it is more plausible to reframe the question of priority in terms of control and responsibility rather than virtue and vice. Given that medical resources like livers are scarce, some people may justifiably be given lower priority than others in receiving these resources.
