Treatments for MS are aimed at prevention of disability in the future or restoring function in the present. Prevention treatments disrupt the underlying disease pathology, whereas restorative treatments address not only the disease’s primary effects on the central nervous system, but also secondary effects on other parts of the body and tertiary effects on each patient’s psychosocial functioning. MS symptoms can have primary, secondary, and tertiary components, which can interlock and reinforce each other. Restorative treatment should tease apart these components and address them separately. In this article on symptom management, we focus on treatments that aim to maximize each component of function.

In this chapter, we first endorse the self-concept view as the most appropriate approach to personal continuity in healthcare. We briefly describe two different types of dementia, Alzheimer’s dementia (AD) and behavioral-variant frontotemporal dementia (bv-FTD). We identify elements considered important for the continuation of a self-concept, including continuation of memories, consistency in personality traits and personal preferences, and continued endorsement of certain moral tenets. We show that, depending on which element is considered most important for personal identity, continuity of a self-concept for individuals with distinct types of dementia will be affected and assessed differently. Utilizing a variety of empirical evidence, we argue that persistence of memory, personality traits, and preferences are not the most important for the maintenance of personal identity. Instead, as studies aimed to capture the folk-psychological view of personal continuity demonstrate, judgements about continuity depend primarily on the persistent commitment to widely shared moral beliefs. Because of that, we argue that individuals with bv-FTD are more likely to lose their sense of self than individuals whose dementia primarily affects memory, such as Alzheimer’s disease. We end the chapter by showing how the importance of moral beliefs for continuity of self can be used to provide guidance to health-care professionals when considering changes in preference by individuals with dementia.

Gamesmanship is non-universalizable and does not exercise a competitive advantage; consequently, it distorts prices and allocates resources inefficiently. This explains why gamesmanship is wrong. This explanation differs from the recent proposal of Heath (2020. Ethical issues in physician billing under fee-for-service plans. J. Med. Philos. 45(1):86–104) that gamesmanship is wrong because of specific features of health care and of health insurance. These features are aggravating factors but do not explain gamesmanship’s primary wrong-making feature, which is to cause diffuse harm not traceable to any particular patient or insurer. This conclusion has important consequences for how medical schools and professional organizations encourage integrity in billing. To avoid free-riding, physicians should ask themselves, “could all physicians bill this way?” and if no...

It is not known which factors predict relapse. Here we describe our clinical experience with MOG-AD and evaluate for factors that correlate with relapsing disease. METHODS This was a retrospective, multi-institutional study of 54 patients with MOG-AD, including 17 children and 37 adults. Mann-Whitney U and Fischer's Exact tests were used for comparisons and logistic regression for correlations. RESULTS Incident attack phenotype included acute disseminated encephalomyelitis (15%), unilateral optic neuritis (ON; 39%), bilateral ON (24%), transverse myelitis (TM; 11%) and ON with TM (11%). Pediatric patients were more likely than adults to present with ADEM (p = .009) and less likely to present with unilateral ON (p = .04). 31 patients (57%) had a relapsing disease course, with time to first relapse of 8.2 months and median annualized relapse rate of 0.97 months. In 40% of patients (n = 22) the first relapse occurred following the withdrawal of treatment for the incident attack. 5 patients converted to seronegative at follow up, 2 of whom later relapsed. Logistic regression revealed no significant relationship between age, gender, race, presentation phenotype, antibody titer, or cerebrospinal fluid results with risk of relapse. For patients who started disease modifying therapy (DMT) prior to the first relapse (n = 11), 64% remained monophasic. 50% (n = 15) of patients on DMT continued to have disease activity, requiring treatment adjustment. CONCLUSIONS It is difficult to predict which patients with MOG-AD will relapse. Research is needed to determine the optimal timing and choice of treatment.

The committee members who interviewed her reported that Emily had spoken movingly about her desire to become a primary care physician in a rural setting. The committee's student member, Jason, looked up Emily on Facebook to see whether they had any friends in common. There he found a link to a blog post that attributed rising rates of contagious disease and unemployment to illegal immigrants. Emily had added: "I couldn't agree more. People whose mothers just happened to sneak over the border at the right time are called 'citizens' when they're just driving down wages, straining our infrastructure, and taking jobs that rightly belong to honest, hardworking taxpayers. Why should we take care of them?" Emily's Facebook post revealed a side of her that Jason knew the admissions committee hadn't seen, and he wondered what he should do with this information.
