Letter re: Ischemic Lesions, blood pressure dysregulation, and poor outcomes in intracerebral hemorrhage
We appreciated the article by Kidwell et al.1 that showed higher first-recorded blood pressure (BP) and greater delta mean arterial pressure are associated with the development of diffusion-weighted imaging (DWI) lesions in acute intracerebral hemorrhage (ICH). The most desirable BP target and optimal antihypertensive strategy in ICH are controversial.2 The relationship between BP and outcome is more complex than simply linear, and mechanisms other than BP reduction play a role. There is accruing evidence that not only absolute BP levels but their variation over time affect ICH prognosis.3 Besides increasing the risk of he...

Fatigable ptosis as an initial presentation of adult-onset Leigh syndrome
A 20-year-old man presented with bilateral fatigable ptosis for 1 month. On examination, there was bilateral incomplete ptosis, which deteriorated during upward gaze and improved at rest (figure, A and B). Tests for myasthenia gravis were all negative. Brain MRI showed symmetric hyperintensities at periaqueductal gray matter on T2- and diffusion-weighted images (figure, C). CSF lactic acid was elevated. Mitochondrial genome test demonstrated a homoplasmic T9176C mutation in the MT-APT6A gene, known as pathogenic mutation of Leigh syndrome.1 In our patient, fatigable ptosis may be ascribed to the dysfunction at centrally lo...

Genome editing technologies and their potential to treat neurologic disease
Genome editing refers to a process of making precise and permanent changes in the genetic code of cells, tissues, and whole organisms. The first step in this process is to program an enzyme called a nuclease to bind to a precise DNA sequence, whereby the enzyme will cut the DNA. This double-stranded break will in turn induce the cell to make a repair at that site, which will change the DNA sequence. The repair mechanism can be utilized to either knock out or introduce selected genes. Given how rapidly gene editing systems are influencing diverse applications in biomedical research, biotechnology, and agriculture,1 clinical...

Qualitative study of burnout, career satisfaction, and well-being among US neurologists in 2016
Conclusions: Our results further characterize burnout among US neurologists through respondents' own voices. They clarify the meaning respondents attributed to ambiguous survey questions and highlight the barriers neurologists must overcome to practice their chosen specialty, including multiple regulatory hassles and increased work hours. Erosion of professionalism by external factors was a common issue. Our findings can provide strategic direction for advocacy and programs to prevent and mitigate neurologist burnout and promote well-being and engagement. (Source: Neurology)

Preventing burnout increases the desirability of neurology as a career
Neurologic diseases comprise a major percentage of disease burden in the United States, and one that is predicted to increase as our population ages. The need for physicians with expertise in the recognition, diagnosis, and management of neurologic diseases also will increase. Over the next decade, the number of neurologists in the United States will grow from the current 16,000 to 18,000. However, even this number represents a predicted 20% shortfall in number of neurologists needed by 2025.1,2 Our neurology workforce therefore must increase to address this current and future need.

An improved way to predict neurologic recovery in acute spinal cord injury
In North America alone, spinal cord injury affects well over 1 million patients, with the average annual incidence expected to rise secondary to an increasing amount of falls in an aging population.1,2 Spinal cord injury (SCI) has detrimental health consequences that can frequently leave the injured patient with a lifetime of medical expenses exceeding $4 million.2 Although the current practice in treating SCI is to elevate a patient's mean arterial pressure (MAP) to 85–90 mm Hg for the first 7 days in an effort to maintain spinal cord perfusion, this treatment strategy has uncertain efficacy, as the actual spinal co...

Nonlinear temporal dynamics of cerebral small vessel disease: The RUN DMC study
Objective: To investigate the temporal dynamics of cerebral small vessel disease (SVD) by 3 consecutive assessments over a period of 9 years, distinguishing progression from regression. Methods: Changes in SVD markers of 276 participants of the Radboud University Nijmegen Diffusion Tensor and Magnetic Resonance Imaging Cohort (RUN DMC) cohort were assessed at 3 time points over 9 years. We assessed white matter hyperintensities (WMH) volume by semiautomatic segmentation and rated lacunes and microbleeds manually. We categorized baseline WMH severity as mild, moderate, or severe according to the modified Fazekas scale. We ...

Outcome after stroke thrombolysis in patients >80 years treated within 3 hours vs >3-4.5 hours
Objective: To determine outcomes and risks of IV thrombolysis (IVT) in patients with acute ischemic stroke (AIS)>80 years of age within 3 hours compared to>3 to 4.5 hours recorded in the Safe Implementation of Treatment in Stroke (SITS) International Stroke Thrombolysis Registry. Methods: A total of 14,240 (year 2003–2015) patients>80 years of age with AIS were treated with IVT ≤4.5 hours of stroke onset (3,558 in>3–4.5 hours). Of these, 8,658 (2,157 in>3–4.5 hours) were treated otherwise according to the European Summary of Product Characteristics (EU SmPC) criteria for alteplase. Outc...

CSF inflammatory response after intraventricular hemorrhage
Conclusions: Aseptic CSF inflammation after IVH is primarily dependent on the volume of initial bleed. Thrombolysis intensifies the inflammatory response, with no apparent detrimental effect on clinical outcome. Clinicaltrials.gov identifier: NCT00784134. (Source: Neurology)

Relevance of supraventricular runs detected after cerebral ischemia
Objective: Prolonged ECG monitoring after stroke frequently reveals short paroxysmal atrial fibrillation (pAF) and supraventricular (SV) runs. The minimal duration of atrial fibrillation (AF) required to induce cardioembolism, the relevance of SV runs, and whether short pAF results from cerebral damage itself are currently being debated. We aimed to study the relevance of SV runs and short pAF detected by prolonged Holter ECG after cerebral ischemia during long-term follow-up. Methods: Analysis is from the prospective Find-AF trial (ISRCTN46104198). We included patients with acute cerebral ischemia. Those without AF on ad...

Striving to improve the quality of stroke care in the USA
Compelling evidence indicates that the organization and delivery of stroke care makes a difference in the chances of patients surviving, their level of disability, and the chances of further strokes. Most evidence-based interventions do not require expensive high-technology medicine but rather need well-organized basic care delivered by people with expertise in stroke. Yet there are many places in the world, including parts of the United States, where high-quality care cannot be guaranteed, resulting in higher than necessary levels of mortality and morbidity.

HIV-related cognitive decline despite viral suppression and complex confounds in American women
In this issue of Neurology®, the Women's Interagency HIV Study (WIHS)1 presents a longitudinal analysis of its American cohort. The cohort is unique because it is large and representative of contemporary women with or at risk of HIV infection the United States. The cohort is ethnically diverse, composed of a substantial number who are economically disadvantaged, and includes participants with mental health issues, including alcohol/drug use (most women report past use of alcohol and recreational drugs, and between 7% and 18% are current users). There were few differences between the women who completed and those who di...
