PurposeWhile there is strong evidence supporting the importance of telemedicine in stroke, its role in other areas of neurology is not as clear. The goal of this review is to provide an overview of evidence-based data on the role of teleneurology in the care of patients with neurologic disorders other than stroke.Recent findingsStudies across multiple specialties report noninferiority of evaluations by telemedicine compared with traditional, in-person evaluations in terms of patient and caregiver satisfaction. Evidence reports benefits in expediting care, increasing access, reducing cost, and improving diagnostic accuracy and health outcomes. However, many studies are limited, and gaps in knowledge remain.SummaryTelemedicine use is expanding across the vast array of neurologic disorders. More studies are needed to validate and support its use.

Posterior reversible encephalopathy syndrome is the most common brain imaging abnormality in severe manifestations of thrombotic thrombocytopenic purpura. Large infarctions and hemorrhage are infrequent. Consequently, abnormal brain neuroimaging does not seem to impact patient outcome, and full neurologic recovery is possible even in comatose patients with extensive brain abnormalities on MRI.

The year 2020 was the year of the nurse, celebrating nurse scholarship, innovation, and leadership by promoting scientific nursing research, improving nursing practice, advancing nursing education, and providing leadership to influence health policy. As architects of stroke care, neuroscience nurses play a vital role in collaborating and coordinating care between multiple health professionals. Nurses improve accessibility and equity through telestroke, emergency medical services, and mobile stroke units and are integral to implementing education strategies by advocating and ensuring that patients and caregivers receive stroke education while safely transitioning through the health care system and to home. Stroke care is increasingly complex in the new reperfusion era, requiring nurses to participate in continuing education while attaining levels of competency in both the acute and recovery care process. Advanced practice nurses are taking the lead in many organizations, serving as prehospital providers on mobile stroke units, participating as members of the stroke response team, and directing stroke care protocols in the emergency department. This scientific statement is an update to the 2009 “Comprehensive Overview of Nursing and Interdisciplinary Care of the Acute Ischemic Stroke Patient.” The aim is to provide a comprehensive review of the scientific evidence on nursing care in the prehospital and hyperacute emergency hospital setting, arming nurses with the necessary tools to provide evidenced-based high-quality care.

Background: Little is known of the nature of the neurologic manifestations in thrombotic thrombocytopenic purpura (TTP). We have recently reported posterior reversible encephalopathy syndrome (PRES) as the predominant brain abnormality in patients with TTP. Posterior reversible encephalopathy syndrome has been associated with a variety of medications and pathologic states including increased arterial blood pressure and renal failure. The factors that predispose patients with TTP to PRES are not known. Objectives: To ascertain whether the presence and degree of hypertension and typical laboratory abnormalities seen in hospitalized patients with TTP are predictors of PRES. Design, Setting, and Patients: We performed a retrospective analysis of brain imaging in 46 hospitalized patients with acute TTP seen at St Mary's and Rochester Methodist hospitals in Rochester, Minnesota, from January 1997 to June 2007. Head computed tomographic scans and brain magnetic resonance images were evaluated independently by 2 investigators. We then performed statistical analysis to determine whether the presence of PRES was associated with the presence of hypertension or abnormal laboratory data, including renal function. Results: Forty-seven incidences of patients having TTP and neuroimaging were evaluated over a 10-year period. Thirty-three patients (70%) had brain magnetic resonance imaging performed. Of the patients who had acute abnormalities on brain magnetic resonance imaging, 13 (48%) were found to have PRES. Degree of hypertension was not associated with PRES on brain magnetic resonance imaging (P = .55). There was no association between hematocrit or platelet nadir, maximum blood urea nitrogen, D dimer, fibrinogen, lactate dehydrogenase, or total bilirubin levels and occurrence of PRES. The only variable highly associated with PRES on neuroimaging was the glomerular filtration rate (P=.02). Conclusion: The occurrence of PRES in patients with acute TTP is associated with worse renal function.
