RESUMO
Light flashes, patterns, or color changes can provoke seizures in up to 1 in 4000 persons. Prevalence may be higher because of selection bias. The Epilepsy Foundation reviewed light-induced seizures in 2005. Since then, images on social media, virtual reality, three-dimensional (3D) movies, and the Internet have proliferated. Hundreds of studies have explored the mechanisms and presentations of photosensitive seizures, justifying an updated review. This literature summary derives from a nonsystematic literature review via PubMed using the terms "photosensitive" and "epilepsy." The photoparoxysmal response (PPR) is an electroencephalography (EEG) phenomenon, and photosensitive seizures (PS) are seizures provoked by visual stimulation. Photosensitivity is more common in the young and in specific forms of generalized epilepsy. PS can coexist with spontaneous seizures. PS are hereditable and linked to recently identified genes. Brain imaging usually is normal, but special studies imaging white matter tracts demonstrate abnormal connectivity. Occipital cortex and connected regions are hyperexcitable in subjects with light-provoked seizures. Mechanisms remain unclear. Video games, social media clips, occasional movies, and natural stimuli can provoke PS. Virtual reality and 3D images so far appear benign unless they contain specific provocative content, for example, flashes. Images with flashes brighter than 20 candelas/m2 at 3-60 (particularly 15-20) Hz occupying at least 10 to 25% of the visual field are a risk, as are red color flashes or oscillating stripes. Equipment to assay for these characteristics is probably underutilized. Prevention of seizures includes avoiding provocative stimuli, covering one eye, wearing dark glasses, sitting at least two meters from screens, reducing contrast, and taking certain antiseizure drugs. Measurement of PPR suppression in a photosensitivity model can screen putative antiseizure drugs. Some countries regulate media to reduce risk. Visually-induced seizures remain significant public health hazards so they warrant ongoing scientific and regulatory efforts and public education.

The human, as a biological system, is an open system embedded within larger systems -including the family, culture, and socio-political environment. In this context, a patient with functional seizures (FS) is embedded in relationships, educational/professional institutions, culture, and society. Both connection to these broader systems and the quality of these connections, as well as the soundness of each system in and of itself, influence the health and well-being of patients in positive or negative ways. The social aspects of life are important determinants of health and quality of life across the lifespan. The current narrative review brings out several overarching themes in patients with FS. Sections on attachment, marriage, social networking, and stigma highlight the central roles of supportive and affirmative relationships across the lifespan. The section on education underscores the importance of keeping children and youth with FS connected within their school environments, as well as managing any barriers - learning difficulties, school response to FS events, stigma, etc.-that can diminish this connection. Finally, the sections on employment and driving highlight the value of being an active participant in one's society. In summary, FS impacts patients across most social aspects of life domains regardless of age - factors that are important when developing biopsychosocial formulations. This review concludes that the multidisciplinary management of FS requires careful assessment of social aspects of life in patients which can then be targeted for treatment, to improve their quality of life, facilitating recovery, and reducing the risk of relapse.

Crisis standards of care have been widely developed by healthcare systems and states in the United States during the COVID-19 pandemic, and in some rare cases have actually been used to allocate medical resources. All publicly available U.S. crisis standards of care with a mechanism for allocating scarce resources make use of the Sequential Organ Failure Assessment (SOFA) score in hopes of assigning scarce resources to those patients who are more likely to survive. We reflect on the growing body of evidence suggesting that the SOFA score has limited accuracy in predicting mortality among patients hospitalized with COVID-19 and that the SOFA score systematically disfavors Black patients. Use of the SOFA score for allocating scarce resources may therefore result in Black patients with equal likelihood of survival being deprived of life-saving medical resources. There is also a risk of injustice for patients with non-COVID-19 diagnoses, for whom the SOFA score may be a more accurate prognostic score, but who might nevertheless be unfairly (de)prioritized when assessed alongside COVID-19 patients using the same scoring system. For these reasons we recommend that the SOFA score not be used for triage purposes during the COVID pandemic, and that a national effort be made to develop and empirically test crisis standards of care in advance of the next public health emergency.

OBJECTIVES: To determine the number of top-ranked U.S. academic institutions that require ethics consultation for specific adult clinical circumstances (e.g., family requests for potentially inappropriate treatment) and to detail those circumstances and the specific clinical scenarios for which consultations are mandated. DESIGN: Cross-sectional survey study, conducted online or over the phone between July 2016 and October 2017. SETTING: We identified the top 50 research medical schools through the 2016 U.S. News and World Report rankings. The primary teaching hospital for each medical school was included. SUBJECTS: The chair/director of each hospital's adult clinical ethics committee, or a suitable alternate representative familiar with ethics consultation services, was identified for study recruitment. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A representative from the adult ethics consultation service at each of the 50 target hospitals was identified. Thirty-six of 50 sites (72%) consented to participate in the study, and 18 (50%) reported having at least one current mandatory consultation policy. Of the 17 sites that completed the survey and listed their triggers for mandatory ethics consultations, 20 trigger scenarios were provided, with three sites listing two distinct clinical situations. The majority of these triggers addressed family requests for potentially inappropriate treatment (9/20, 45%) or medical decision-making for unrepresented patients lacking decision-making capacity (7/20, 35%). Other triggers included organ donation after circulatory death, initiation of extracorporeal membrane oxygenation, denial of valve replacement in patients with subacute bacterial endocarditis, and posthumous donation of sperm. Twelve (67%) of the 18 sites with mandatory policies reported that their protocol(s) was formally documented in writing. CONCLUSIONS: Among top-ranked academic medical centers, the existence and content of official policies regarding situations that mandate ethics consultations are variable. This finding suggests that, despite recent critical care consensus guidelines recommending institutional review as standard practice in particular scenarios, formal adoption of such policies has yet to become widespread and uniform.

Psychogenic nonepileptic seizures (PNES) are a highly disabling disorder frequently encountered by neurologists, psychiatrists, and emergency medicine physicians. There is accumulating evidence for the efficacy of psychological therapies, yet the majority of patients do not complete treatment. A range of health care system-based, clinician-based, and patient-based barriers to treatment exists, including stigma, poor clinician-patient communication, and patient ambivalence about the diagnosis and treatment of PNES. These barriers frequently lead to treatment nonadherence. Motivational interviewing (MI) is a patient-centered counseling style targeting ambivalence about behavior change, which has been shown to be effective in improving psychotherapy adherence and outcomes among patients with PNES. The authors review MI processes and techniques that may be useful to health care providers helping patients with PNES and other functional neurological disorders to engage in psychotherapy. The authors examine common challenges arising during MI for patients with PNES, including somatic symptoms distracting from clinician-patient communication, ambivalence about making concrete plans for treatment, and psychiatric comorbidities. Strategies for overcoming these obstacles are reviewed, including the use of complex reflections to enhance patient engagement; the use of an ask-tell-ask format and specific, measurable, achievable, relevant, and time-limited (SMART) goals to facilitate treatment planning; and close collaboration between the neurology and psychotherapy teams.

Shortages of life-saving medical resources caused by COVID-19 have prompted hospitals, healthcare systems, and governmentsto develop crisis standards of care, including 'triage protocols' to potentially ration medical supplies during the public health emergency. At the same time, the pandemic has highlighted and exacerbated racial, ethnic, and socioeconomic health disparities that together constitute a form of structural racism. These disparities pose a critical ethical challenge in developing fair triage systems that will maximize lives saved without perpetuating systemic inequities. Here we review alternatives to 'utilitarian' triage, including first-come first-served, egalitarian, and prioritarian systems of allocating scarce medical resources. We assess the comparative advantages and disadvantages of these allocation schemes. Ultimately, we argue that while triage protocols should not exacerbate disparities, they are not an adequate mechanism for redressing systemic health inequities. Entrenched health disparities must be addressed through broader social change.
RESUMO
The coronavirus disease-2019 (COVID-19) has caused shortages of life-sustaining medical resources, and future waves of the virus may cause further scarcity. The Yale New Haven Health System developed a triage protocol to allocate scarce medical resources during the COVID-19 pandemic, with the primary goal of saving the most lives possible, and a secondary goal of making triage assessments and decisions consistent, transparent, and fair. We outline the process of developing the triage protocol, summarize the protocol itself, and discuss the major ethical challenges encountered, along with our answers to these challenges. These challenges include (1) the role of age and chronic comorbidities; (2) evaluating children and pregnant patients; (3) racial, ethnic, and socioeconomic disparities in health; (4) prioritization of healthcare workers; and (5) balancing clinical judgment versus protocolized assessments. We conclude with a review of the limitations of our protocol and the lessons learned. We hope that a robust public discussion of such protocols and the ethical challenges that they raise will result in the fairest possible processes, less need for triage, and more lives saved during future waves of the COVID-19 pandemic and similar public health emergencies.

OBJECTIVE: We conducted a randomized controlled trial of motivational interviewing (MI) as an intervention to improve psychotherapy adherence and outcomes, including frequency of psychogenic nonepileptic seizures (PNES), quality of life, and emergency department utilization, among participants with PNES. METHODS: Sixty participants were randomized to receive either psychotherapy alone or MI plus psychotherapy. Participants and therapists were contacted at 16-week follow-up. Participants were considered adherent with psychotherapy if they attended at least eight sessions within 16 weeks following referral. RESULTS: Among control participants, 31.0% were adherent, whereas among MI participants, 65.4% were adherent (P = 0.015, absolute risk reduction = 34.4%, number needed to treat = 2.9). In the control arm, PNES frequency decreased by 34.8% (standard deviation [SD] = 89.7%), whereas in the MI arm, PNES frequency decreased by 76.2% (SD = 39.2%; P = 0.034, Cohen's d = 0.59). Among control participants, 10.7% achieved PNES freedom versus 30.8% of MI participants (P = 0.095). Quality of Life in Epilepsy-10 scores (a 40-point scale) improved by an average of 1.8 (SD = 7.9) points among control participants, and by 7.2 (SD = 10.0) points among MI participants (P = 0.047, Cohen's d = 0.60). Monthly emergency department visits increased by 0.06 (SD = 0.47) visits per month among control participants versus a decrease of 0.15 (SD = 0.76) among MI participants (P = 0.23). SIGNIFICANCE: Motivational interviewing improved treatment adherence, PNES frequency, and quality of life among our participants with PNES. Our study is limited in that it was conducted at a single quaternary care medical center, and MI was provided by a single neurologist, which may limit generalization of results.

We conducted a prospective cohort study, examining long-term adherence with psychiatric treatment among patients with psychogenic nonepileptic seizures (PNES). Subjects diagnosed with documented PNES were scheduled for 4 psychiatric visits. Survival analysis was performed, and covariates were assessed for association with time to nonadherence using Cox proportional hazard regression analysis. One hundred twenty-three subjects were recruited and followed for up to 17 months. Eighty percent of subjects attended the first outpatient visit, 42% attended the second, 24% attended the third, and only 14% remained adherent through the fourth visit. Two covariates were associated with nonadherence: (1) a prior diagnosis of PNES (hazard ratio 1.57, P-value .046); (2) a lower score on the Brief Illness Perception Questionnaire (BIPQ), signifying lower concern about one's illness (hazard ratio 0.77 for every 10-point increment on the 80-point scale, P-value .008). Adherence with psychiatric treatment among patients with PNES is initially reasonably good but worsens rapidly over visits 2-4. Risk factors for nonadherence include a history of a prior diagnosis of PNES, and a lower level of concern about the illness as assessed by a lower score on the BIPQ.

Neurologists regularly confront complex clinical scenarios that require the application of ethical principles to achieve a respectful and fair resolution. In this article, we describe the types of ethically precarious scenarios neurologists encounter, the current status of standards for ethics and communication training for neurology residents, and the present practice of ethics training in neurology residency programs. We make recommendations for optimizing bioethics training for neurology residents and suggest methods for assessing the efficacy of these training initiatives. We emphasize the current need for strengthening the practical bioethics skills of neurologists.

The use of the Sequential Organ Failure Assessment (SOFA) score, originally developed to describe disease morbidity, is commonly used to predict in-hospital mortality. During the COVID-19 pandemic, many protocols for crisis standards of care used the SOFA score to select patients to be deprioritized due to a low likelihood of survival. A prior study found that age outperformed the SOFA score for mortality prediction in patients with COVID-19, but was limited to a small cohort of intensive care unit (ICU) patients and did not address whether their findings were unique to patients with COVID-19. Moreover, it is not known how well these measures perform across races. In this retrospective study, we compare the performance of age and SOFA score in predicting in-hospital mortality across two cohorts: a cohort of 2,648 consecutive adult patients diagnosed with COVID-19 who were admitted to a large academic health system in the northeastern United States over a 4-month period in 2020 and a cohort of 75,601 patients admitted to one of 335 ICUs in the eICU database between 2014 and 2015. We used age and the maximum SOFA score as predictor variables in separate univariate logistic regression models for in-hospital mortality and calculated area under the receiver operator characteristic curves (AU-ROCs) and area under precision-recall curves (AU-PRCs) for each predictor in both cohorts. Among the COVID-19 cohort, age (AU-ROC 0.795, 95% CI 0.762, 0.828) had a significantly better discrimination than SOFA score (AU-ROC 0.679, 95% CI 0.638, 0.721) for mortality prediction. Conversely, age (AU-ROC 0.628 95% CI 0.608, 0.628) underperformed compared to SOFA score (AU-ROC 0.735, 95% CI 0.726, 0.745) in non-COVID-19 ICU patients in the eICU database. There was no difference between Black and White COVID-19 patients in performance of either age or SOFA Score. Our findings bring into question the utility of SOFA score-based resource allocation in COVID-19 crisis standards of care.

Purpose: Functional seizures (FS) cause significant long-term disability and clinicians offer differing views on proper work restrictions and qualifications for disability benefits in this population. We assess the views and perspectives of experienced disability and work limitations in people living with functional seizures. Methods: Between (4/29/2020-1/13/2021) an open-access 21-item internet survey was conducted via FNDHope.org; allowing for people living with self-reported functional seizures to remark on topics of work difficulties, work restrictions, qualifications for disability benefits, and driving. Demographic information was collected, and univariate and multivariate logistic regressions were used to evaluate potential predictors of current employment status. Results: One hundred eighteen (118) responses were received, of which 92 (84.4%) completed > 50% of the survey; they were predominantly (92%) female. Most respondents (88%) reported some personal difficulty at work and nearly all (99%) believed that others with FS would experience difficulties in the workplace. A majority (71%) felt that work restrictions should apply to people living with active FS, at least in certain lines of work. Most (64%) felt people with FS should qualify for disability benefits; however, 35% stated work accommodations or a new job compatible with FS was more appropriate. Of those who felt people with FS should qualify for disability, 60% thought recipients should remain eligible for disability while symptomatic and 38% felt benefits should be lifelong. In univariate and multivariate logistic regressions, older age was predictive of unemployment (univariate OR 0.95 ± 0.02, 95% CI 0.92-0.98, p-value 0.002). Conclusion: Our results suggest that work difficulties are common in people with FS, with older age being a predictor of unemployment. A majority of people with FS support work restrictions for those with their disorder, at least in some lines of work. In comparison to a prior study of clinicians, a higher percentage of people with FS supported work restrictions. These results may help facilitate productive discussions between people with FS, providers, and policymakers regarding appropriate work and disability limitations.
RESUMO
Functional or psychogenic seizures have proved a diagnostic and therapeutic challenge for centuries. Functional seizures can look and feel similar to epileptic seizures but are instead a common and highly disabling form of functional neurologic disorder, or conversion disorder. Consistent with the biopsychosocial model of mental illness, functional seizures are caused by biological, psychological, and social factors unrelated to epileptic discharges. People with functional seizures do not consciously fake their symptoms. Functional seizures can be differentiated from epileptic seizures through the clinical history, features of the seizures themselves, and electroencephalography findings. Psychotherapy is effective in treating functional seizures.

Ethical obligations to minimize harms and maximize benefits of diagnosis and treatment of disorders without biomarkers include navigating difficult-to-measure, perhaps clinically inexplicable, symptoms. Among potential harms are public stigma, self-stigma, label avoidance, and the negative influence these stigmas have on self-esteem, quality of life, employment, and housing. Among potential benefits are patients becoming active agents in managing their illnesses, social acceptance, and access to evidence-based treatments. Ethical complexities clinicians face when trying to develop treatment plans while heeding key details from patients' narrative accounts prompt questions about how to best adhere to evidence in understudied domains of medicine.

Functional seizures (FS) are frequently encountered in neurology clinics, often affect young adults, and have significant negative impacts on many aspects of a person's life. In the current narrative review, we searched the literature regarding some of the consequences of FS (i.e., psychiatric comorbidities, social consequences, costs that are associated with the condition, cognitive impairment in patients with FS, the quality of life of the people with FS, and the increased risk of mortality that is associated with FS). Evidence shows that FS have significant negative consequences, comparable in their magnitude to those affecting patients with epilepsy. The clinical and scientific communities should take steps to address these consequences through clinical care and research that prioritizes, facilitates, and expedites evidence-based diagnosis and treatment for FS.
