The World Health Organization (WHO) classification of central nervous system (CNS) tumors was revised in 2016 with a basis on the integrated diagnosis of molecular genetics. We herein provide the guidelines for using molecular genetic tests in routine pathological practice for an accurate diagnosis and appropriate management. While astrocytomas and IDH-mutant (secondary) glioblastomas are characterized by the mutational status of IDH, TP53 , and ATRX , oligodendrogliomas have a 1p/19q codeletion and mutations in IDH, CIC , FUBP1 , and the promoter region of telomerase reverse transcriptase ( TERTp )...

BACKGROUND: Chronic neck pain affects 50% - 85% of people who have experienced an acute episode. This transition and the persistence of chronic complaints are believed to be mediated by brain alterations among different central mechanisms. OBJECTIVES: This study aimed to systematically review and critically appraise the current existing evidence regarding structural and functional brain alterations in patients with whiplash associated disorders (WAD) and idiopathic neck pain (INP)...

Immunity and inflammation are important parameters of the pathophysiology of stroke, a destructive illness that is the second most common cause of death worldwide. Following ischemic stroke, neuroinflammation plays a critical role in neurodegeneration and brain injury. MicroRNAs (miRNAs) are a class of endogenously expressed, noncoding RNA molecules that function to inhibit mRNA translation. Recent studies demonstrate that miRNAs are key regulators of inflammatory processes contributing to ischemic stroke injuries...

Globally, more than 20% of women of reproductive age are currently estimated to be obese. Children born to obese mothers are at higher risk of developing obesity, coronary heart disease, diabetes, stroke, and asthma in adulthood. Increasing clinical and experimental evidence suggests that maternal obesity also affects the health and function of the offspring brain across the lifespan. This review summarizes the current findings from human and animal studies that detail the impact of maternal obesity on aspects of learning, memory, motivation, affective disorders, attention-deficit hyperactivity disorder, autism spectrum disorders, and neurodegeneration in the offspring...

J A Sutton, R P Clauss
During 15 years, 23 clinical reports and 6 studies have demonstrated associations between sub-sedative doses of zolpidem and recoveries from brain damage due to strokes, trauma and hypoxia. Clinical findings include unexpected awakenings from vegetative states and regressions of stroke symptoms after dosing that disappear during elimination and reappear on repeat dosing. Initially single-photon emission computed tomography scans showed improved perfusion within, around and distant from infarctions. Then positron emission tomography scans and electroencephalography detected renewed metabolic and neuronal activity...

PURPOSE OF REVIEW: Schizophrenia has been hypothesized to be a syndrome of accelerated aging. Brain plasticity is vulnerable to the normal aging process and affected in schizophrenia: brain-derived neurotrophic factor (BDNF) is an important neuroplasticity molecule. The present review explores the accelerated aging hypothesis of schizophrenia by comparing changes in BDNF expression in schizophrenia with aging-associated changes. RECENT FINDINGS: Individuals with schizophrenia show patterns of increased overall mortality, metabolic abnormalities, and cognitive decline normally observed later in life in the healthy population...

Microglia, of myeloid origin, play fundamental roles in the control of immune responses and the maintenance of central nervous system homeostasis. These cells, just like peripheral macrophages, may be activated into M1 pro-inflammatory or M2 anti-inflammatory phenotypes by appropriate stimuli. Microglia do not respond in isolation, but form part of complex networks of cells influencing each other. This review addresses the complex interaction of microglia with each cell type in the brain: neurons, astrocytes, cerebrovascular endothelial cells, and oligodendrocytes...

It is becoming increasingly clear that neuroinflammation has a causal role in the pathogenesis of central nervous system (CNS)-related diseases, and therefore therapeutic strategies targeting the regulation or availability of inflammatory mediators can be used to prevent or mitigate pathology. Interestingly, the proinflammatory cytokine, interleukin-1 beta (IL-1β), has been implicated in perpetuating immune responses and contributing to disease severity in a variety of CNS diseases ranging from multiple sclerosis, neurodegenerative diseases, traumatic brain injury, and diabetic retinopathy...

PURPOSE: Familial cerebral cavernous malformation (CCM) patients present with multiple lesions that can grow both in number and size over time and are reliably detected on susceptibility-weighted imaging (SWI). Manual counting of lesions is arduous and subject to high variability. We aimed to develop an automated algorithm for counting CCM microbleeds (lesions <5 mm in diameter) on SWI images. METHODS: Fifty-seven familial CCM type-1 patients were included in this institutional review board-approved study...

O-linked β-N-acetylglucosaminylation (O-GlcNAcylation) is involved in the regulation of many cellular cascades and neurological diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and stroke. In the brain, the expression of O-GlcNAcylation is notably heightened, as is that of O-linked N-acetylglucosaminyltransferase (OGT) and β-N-acetylglucosaminidase (OGA), the presence of which is prominent in many regions of neurological importance. Most importantly, O-GlcNAcylation is believed to contribute to the normal functioning of neurons; conversely, its dysregulation participates in the pathogenesis of neurological disorders...

PURPOSE OF REVIEW: Research on psychological well-being in later life has identified strengths and vulnerabilities that occur with aging. We review the conceptual and philosophical foundations of a eudaimonic model of well-being and its empirical translation into six key dimensions of positive functioning. We also consider its implications for health, broadly defined. RECENT FINDINGS: Numerous findings from national longitudinal samples of U.S. adults are described...

Inflammatory myofibroblastic tumor (IMT) is a rare entity and a diagnostic challenge with myriad clinical presentations and pathogenetic mechanisms. Isolated occurrences can be at any site in the body; however, only a few cases of IMT with the concomitant appearance of different organs have been published. We report a unique occurrence of bilateral inflammatory myofibroblastic tumor of the lungs with synchronous brain parenchymal lesions in an 11-year-old male, detailing clinical presentation with the emphasis on imaging and review of the literature...

Cancer remains one of the most common causes of death and disability and represents a major economic burden in industrialized nations. The renin-angiotensin system (RAS) has been well-recognized as one of the most important regulators of both normal and pathological physiological processes in the brain, kidney, heart, and blood vessels. The activation of the angiotensin-converting enzyme 2/angiotensin-(1-7)/mitochondrial assembly receptor [ACE2/Ang-(1-7)/MasR] axis, which is one component of the RAS, has recently been identified as a critical component of pulmonary systems, gastric mucosa, and cancer...

Neonatal hypoxia-ischaemia (HI) is the most common cause of death and disability in human neonates, and is often associated with persistent motor, sensory, and cognitive impairment. Improved intensive care technology has increased survival without preventing neurological disorder, increasing morbidity throughout the adult population. Early preventative or neuroprotective interventions have the potential to rescue brain development in neonates, yet only one therapeutic intervention is currently licensed for use in developed countries...

Most medical specialties including the field of gastroenterology are mainly aimed at treating diseases rather than preventing them. Genomic medicine studies the health/disease process based on the interaction of the human genes with the environment. The gastrointestinal (GI) system is an ideal model to analyze the interaction between our genes, emotions and the gut microbiota. Based on the current knowledge, this mini-review aims to provide an integrated synopsis of this interaction to achieve a better understanding of the GI disorders related to bad eating habits and stress-related disease...

Return to drive after brain damage is a crucial question either for patients than health professionals. The Société française de medicine physique et de réadaptation (SOFMER) and Comète France association developed recommandations for patient's identification, evaluation and accompaniment as part of their project to resume to drive. The place of rehabilitation process and patient's focus has been also discussed. AIMS: Using a literature review, the aim was to define clinical pathways to determine people who need a fitness to drive evaluation after a non-evolutive brain damage as well as the assessment process...

Traumatic brain injury (TBI) is a leading cause of mortality and long-term morbidity worldwide. Despite decades of pre-clinical investigation, therapeutic strategies focused on acute neuroprotection failed to improve TBI outcomes. This lack of translational success has necessitated a reassessment of the optimal targets for intervention, including a heightened focus on secondary injury mechanisms. Chronic immune activation correlates with progressive neurodegeneration for decades after TBI; however, significant challenges remain in functionally and mechanistically defining immune activation after TBI...

L Turco, D L Cornell, B Phillips
BACKGROUND: Head injuries that cross midline structures of the brain are 'bihemispheric.' Other terms have been used to describe such injuries, but 'bihemispheric' is the most accurate and should be standard nomenclature. Bihemispheric head injuries are associated with higher mortality and morbidity than other penetrating traumatic brain injuries (TBI). Currently, there is a tendency to manage severe gunshot wounds (GSWs) to the head non-operatively, despite reports of improved outcome in military patients treated aggressively...

Pain is a common non-motor symptom of Parkinson's disease (PD) that markedly impacts patients' quality of life. Although pain occurs mostly secondary to motor disability of PD, pain may antedate motor symptoms by years. Numerous studies have shown that PD patients manifest altered sensory and pain thresholds compared with control subjects. Although both levodopa and deep brain stimulation improve motor symptoms, there remains no direct correlation between motor improvement and altered pain sensitivity, suggesting that motor symptoms and pain do not necessarily share pathogenetic mechanisms...
