Savina Reid, Haley Thompson, Kiran T Thakur
Neurological complications of infectious diseases are associated with high rates of morbidity and mortality. It is imperative that neurologists be up-to-date on current developments including typical and atypical presentations of neurological infections in travelers, diagnostic and treatment recommendations, and emerging pathogen resistance patterns to avoid fatal outcomes and long-term sequelae. This article will address concepts of emerging and reemerging infectious diseases, and will provide updates on the neurological manifestations of select emerging and reemerging infections, including Ebola virus, bacterial meningitis, enterovirus 71, Zika virus, cerebral malaria, and Japanese encephalitis...

With the advent of combination antiretroviral therapies, the mortality rate from HIV has declined, while the prevalence of long-term HIV-related neurologic complications continues to rise. Thirty-six million individuals are living with HIV around the world, many of whom reside in resource-limited settings. The majority of studies have focused on individuals residing in the developed world, while the impact of HIV disproportionately affects people living in developing countries. This review focuses on recent domestic and international studies regarding neurologic complications related to HIV, including opportunistic infections, peripheral neuropathy, cerebrovascular disease, and HIV-associated neurocognitive disorders, in light of the growing population affected by these conditions...

Central nervous system (CNS) involvement of tuberculosis (TB) is the most severe manifestation of TB and accounts for approximately 5 to 10% of all extrapulmonary TB (EPTB) cases and approximately 1% of all TB cases. TB meningitis (TBM) is the most common form of CNS TB, though other forms occur, often in conjunction with TBM, including intracranial tuberculomas, tuberculous brain abscesses, and spinal tubercular arachnoiditis. CNS TB often presents with nonspecific clinical features that mimic symptoms of other neurological conditions, often making diagnosis difficult...

Bassem I Yamout, Raed Alroughani
Multiple sclerosis (MS) is a chronic central nervous system inflammatory disease of autoimmune etiology, mediated by activated T cells with evolving evidence of a significant contribution from B cells and cells of the innate immune system. The disease is thought to be due to a complex interaction between different genetic and environmental factors. The prevalence of MS is rising all over the world, due on one hand to earlier diagnosis and prolonged survival, and on the other to a true increase in incidence of the disease...

Mira Katan, Andreas Luft
Stroke is the second leading cause of death and a major cause of disability worldwide. Its incidence is increasing because the population ages. In addition, more young people are affected by stroke in low- and middle-income countries. Ischemic stroke is more frequent but hemorrhagic stroke is responsible for more deaths and disability-adjusted life-years lost. Incidence and mortality of stroke differ between countries, geographical regions, and ethnic groups. In high-income countries mainly, improvements in prevention, acute treatment, and neurorehabilitation have led to a substantial decrease in the burden of stroke over the past 30 years...

Neurologic disorders contribute significantly to both morbidity and mortality among children in resource-limited settings, but there are a few succinct studies summarizing the epidemiology of neurologic disorders in these settings. A review of available literature was performed to identify data on the prevalence, etiology, outcomes, and treatment of neurologic disorders in children in resource-limited settings. The burden of neurologic disorders in children is high in resource-limited settings. Barriers to optimal care include lack of trained personnel, limited access to diagnostic technology, and limited availability of drugs used to treat common conditions...

Epilepsy is a frequently misunderstood and highly stigmatized condition. Major treatment gaps exist across the world, most so in areas of financial constraint. Classification permits the best approaches to treatment and to ascertaining prognosis. The International League Against Epilepsy's new classification system emphasizes clinical aspects and utilizes all available resources to determine whether it is a focal or generalized epilepsy. The most important tools are a careful history, clinical examination, electroencephalography, and appropriate neuroimaging...

At the turn of the century, most of the world's population lived in regions where the prevalence of headache was unknown and its impact poorly understood. Lifting The Burden (LTB), a nonprofit organization in official relations with the World Health Organization, established the Global Campaign against Headache, with the ultimate purpose of reducing the burden of headache worldwide. First, the scope and scale of this burden had to be known. LTB embarked upon a program of population-based studies in countries in all world regions in order to achieve its aim...

"Stem cell tourism" is defined as the unethical practice of offering unproven cellular preparations to patients suffering from various medical conditions. This phenomenon is rising in the field of neurology as patients are requesting information and opportunities for treatment with stem cells for incurable conditions such as multiple sclerosis and amyotrophic lateral sclerosis, despite their clinical research and experimental designation. Here, we review the recent trends in "stem cell tourism" in both the United States and abroad, and discuss the recent reports of neurological complications from these activities...

Emerging viral infections of the nervous system represent a major global public health concern in the 21st century. They are caused primarily by RNA viruses and are mostly associated with acute or subacute encephalitis. The spectrum of associated central or peripheral nervous system disorders is broad, and results either from a direct viral effect or due to the host immune responses against the infection. Emerging viral infections impose substantial neurological morbidity and mortality, particularly in low- and middle-income regions...

According to the United Nations Refugee Agency (UNHCR), 65.6 million people have been forcibly displaced worldwide. Several factors have a major influence on asylum seekers' health; so, their health profile is markedly different from that of the population in the country of asylum. The aim of this study is to review the major issues physicians need to be aware of when treating asylum seekers, with a special focus on the neurological problems of asylum seekers and refugees. The major impact factors on refugees' health are linked to experiences and exposure (1) in the country of origin, (2) in refugee camps and en route to Europe, and (3) in the process of immigration into the host country and living in European asylum centers...

Neurology has not typically been associated with international relief work; however, with the growth of chronic cardiovascular disease and stroke associated with unhealthy eating and sedentary ways, the appearance of "new" neurologic diseases, such as the Zika and West Nile viruses, and the high numbers of seizure disorders resulting from neuroinfectious diseases, more opportunities are arising for international and globally oriented neurologists. Multiple opportunities exist for developing a global clinician-educator career pathway, including private institutions, nongovernmental organizations, government-funded opportunities such as Medical Education Partnership Initiative, Fogarty and Fulbright Scholarships, and the American Academy of Neurology's Global Health Section...

Mariella G Filbin, Dominik Sturm
Gliomas are the most common primary central nervous system (CNS) neoplasms in children and adolescents and are thought to arise from their glial progenitors or stem cells. Although the exact cells of origin for most pediatric gliomas remain to be identified, our current understanding is that specific cell populations during CNS development are susceptible to particular oncogenic events during certain time windows and thus give rise to pediatric gliomas with distinct histological, molecular, and clinical features...

Nancy Wang, Matthias Osswald
The majority of meningiomas, the most common primary brain tumor, are considered to be benign, and characteristic magnetic resonance imaging features allow a preliminary diagnosis. Meningiomas can be classified in the World Health Organization system as grade I, II, or III, depending on various histological features. In many cases, observation is the preferred management option, although this means the absence of a histological diagnosis. If necessary, standard therapy consists of surgery with or without adjuvant radiation, depending on the tumor grade and the degree of resection...

Elizabeth R Gerstner, Kristian W Pajtler
Ependymoma can arise throughout the whole neuraxis. In children, tumors predominantly occur intracranially, whereas the spine is the most prevalent location in adults. Significant variance in the grade II versus grade III distinction of ependymomas has led to the acknowledgment that the clinical utility of histopathological classification is limited. Epigenomic profiling efforts have identified molecularly distinct groups of ependymomas that adequately reflect the biological, clinical, and histopathological heterogeneities across anatomical compartments, age groups, and grades...

Brain metastases (BMs) reflect an area of high clinical need, as up to 40% of patients with metastatic cancer will develop this morbid and highly fatal complication. Historically, treatment strategies have relied on local approaches including radiosurgery, whole-brain radiotherapy, and neurosurgical resection. Recently, targeted and immune-modulating therapies have shown promising responses and have been introduced in the clinical management of patients with BMs. Recent improvements in genomic technologies have enriched our understanding of BMs and have demonstrated that BMs present with significant genetic divergence from the originating primary tumor, such that potentially targetable genetic alterations are detected only in the BMs...

Sarah Löw, Tracy T Batchelor
Primary central nervous system lymphoma (PCNSL) is an extranodal non-Hodgkin lymphoma limited to the brain, spinal cord, leptomeninges, and eyes. The majority of patients are immunocompetent, with a median age of 65 years at diagnosis. Historically, whole-brain radiation therapy (WBRT) was the first and sole treatment for PCNSL. Today, due to the recognized neurotoxicity of WBRT, this modality is usually avoided in the treatment. Most chemotherapy regimens are based on high-dose methotrexate plus the anti-CD20 monoclonal antibody rituximab, leading to high response rates, but 5-year survival is still poor at approximately 30% compared with other extranodal lymphomas...
