Importance Functional neurological disorders (FND) are common sources of disability in medicine. Patients have often been misdiagnosed, correctly diagnosed after lengthy delays, and/or subjected to poorly delivered diagnoses that prevent diagnostic understanding and lead to inappropriate treatments, iatrogenic harm, unnecessary and costly evaluations, and poor outcomes. Observations Functional Neurological Symptom Disorder/Conversion Disorder was adopted bythe Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, replacing the termpsychogenicwithfunctionaland removing the criterion of psychological stress as a prerequisite for FND. A diagnosis can now be made in an inclusionary manner by identifying neurological signs that are specific to FNDs without reliance on presence or absence of psychological stressors or suggestive historical clues. The new model highlights a wider range of past sensitizing events, such as physical trauma, medical illness, or physiological/psychophysiological events. In this model, strong ideas and expectations about these events correlate with abnormal predictions of sensory data and body-focused attention. Neurobiological abnormalities include hypoactivation of the supplementary motor area and relative disconnection with areas that select or inhibit movements and are associated with a sense of agency. Promising evidence has accumulated for the benefit of specific physical rehabilitation and psychological interventions alone or in combination, but clinical trial evidence remains limited. Conclusions and Relevance Functional neurological disorders are a neglected but potentially reversible source of disability. Further research is needed to determine the dose and duration of various interventions, the value of combination treatments and multidisciplinary therapy, and the therapeutic modality best suited for each patient.

Background: To compare drug regimens across clinical trials in Parkinson's disease (PD) conversion formulae between antiparkinsonian drugs have been developed. These are reported in relation to levodopa as the benchmark drug in PD pharmacotherapy as ‘levodopa equivalent dose’ (LED). Currently, the LED conversion formulae proposed in 2010 by Tomlinson et al. based on a systematic review are predominantly used. However, new drugs with established and novel mechanisms of action and novel formulations of longstanding drugs have been developed since 2010. Therefore, consensus proposals for updated LED conversion formulae are needed.Objectives: To update LED conversion formulae based on a systematic review.Methods: The MEDLINE, CENTRAL, and Embase databases were searched from January 2010 to July 2021. Additionally, in a standardized process according to the GRADE grid method, consensus proposals were issued for drugs with scarce data on levodopa dose equivalency.Results: The systematic database search yielded 3076 articles of which 682 were eligible for inclusion in the systematic review. Based on these data and the standardized consensus process, we present proposals for LED conversion formulae for a wide range of drugs that are currently available for the pharmacotherapy of PD or are expected to be introduced soon.Conclusions: The LED conversion formulae issued in this Position Paper will serve as a research tool to compare the equivalence of antiparkinsonian medication across PD study cohorts and facilitate research on the clinical efficacy of pharmacological and surgical treatments as well as other non‐pharmacological interventions in PD. © 2023 The Authors.

Background: Hyperglycemia at the time of acute ischemic stroke has been linked to worse outcome in both human and animal studies. Objective: To describe the prevalence and severity of hyperglycemia on hospital admission among acute ischemic stroke patients, to examine the independent relationship of admission hyperglycemia to all-cause mortality, and to document the inpatient management of hyperglycemia. Methods: Patients hospitalized with acute ischemic stroke at one hospital from July 1993 to June 1998 (n = 656) were identified. Demographic data, diagnoses, and blood glucose (BG) values were retrieved from the electronic medical record system. Admission stroke severity, fingerstick BG results, and new diabetes diagnoses were obtained by chart review. Hyperglycemia was defined as admitting random serum BG ≥ 130 mg/dL. Hazard ratios (HR) for 30-day, 1-year, and 6-year mortality were calculated using multivariable Cox regression models. Results: Hyperglycemia at admission to hospital was present in 40% of patients with acute stroke. Patients with hyperglycemia were more often women and more likely to have prior diagnoses of diabetes and heart failure. Almost all of these patients remained hyperglycemic during their hospital stay (mean BG = 206 mg/dL), and 43% received no inpatient hypoglycemic drugs. Hyperglycemic patients had longer hospital stay (7 vs 6 days, p = 0.015) and higher inpatient hospital charges ($6,611 vs $5,262, p < 0.001). Hyperglycemia independently increased the risk for death at 30 days (HR 1.87, p ≤ 0.01), 1 year (HR 1.75, p ≤ 0.01), and 6 years after stroke (HR 1.41, p ≤ 0.01). Conclusions: Admitting hyperglycemia was common among patients with acute ischemic stroke and was associated with increased short- and long-term mortality and with increased inpatient charges. Inpatient blood glucose management was suboptimal in this hospital. A trial of intensive treatment of hyperglycemia should be considered.
