Aging is one of the major risk factors for the onset and progression of various neurodegenerative diseases. Neuroinflammation is a common feature of virtually every central nervous system disease, and is acknowledged as a likely mediator of cognitive impairments. Systemic inflammation levels are augmented with advanced age and neurodegeneration. The influence of age on neuroinflammatory responses including glial activation, increased production of proinflammatory cytokines, and aberrant neuronal signaling could magnify the deterioration of the central nervous system microenvironment in disease, and may contribute to enhanced cognitive impairment. This eBook is a collection of highly informative original research articles, providing comprehensive aspect of neuroinflammation and possible therapeutic interventions in rescuing cognitive impairments.

The brain and immune system are involved in an intricate network of bidirectional communication. This relationship is vital for optimal physiological and psychological development and functioning but can also result in unwanted outcomes. In particular, this interaction plays an important role in cognition, mood and behaviour. Neuroinflammation is known to contribute to neurological and affective disorders including impaired learning and memory, depressive, anxiety and schizoaffective symptoms, as well as pain. The development of these conditions often occurs on the backdrop of pre-existing physical illnesses which give rise to increased activation of the immune system, such as cancer, obesity, infection and autoimmune disorders. Similarly, psychological states can alter regulation of the immune system. This has been most extensively studied in the context of stress and immune function. Understanding the underlying mechanisms that lead to the onset of inflammation-induced neuropathology and stress-induced immune suppression will contribute to the development of novel and effective treatment strategies for both the disease and its neurological side effects. In this research topic we explored the relationship between the immune system and the brain throughout life. We include both original research and review papers from animal, clinical and molecular perspectives.

1 in 6 people suffer from brain diseases like MS, Parkinson’s, and Alzheimer’s. Now, a Harvard neurologist takes you inside the brain under attack—and illuminates the path to a cure. Multiple Sclerosis. Parkinson’s Disease. Alzheimer’s. ALS. Chances are, you know someone with a neurologic disease. Because the brain controls so much and is integral to our identity, the diseases that affect it are uniquely devastating both to patients and families. And because it remains the most mysterious of our vital organs, treating the brain is an ongoing puzzle. In The Brain Under Siege, Howard Weiner likens the brain to a crime scene, showing readers how “clues” point to causes and suggest paths to a cure. He takes readers on a journey through the latest technological advances, exploring which routes of investigation have gone cold and which have led to breakthroughs. Readers couldn’t ask for a better guide: A professor of neurology at Harvard Medical School and co-director of the Ann Romney Center for Neurologic diseases, Weiner is an internationally renowned expert, who pioneered immunotherapy in MS and is currently investigating an Alzheimer’s vaccine. Informative and engaging, this groundbreaking book tells the story behind the science—painting a picture of the discoveries, setbacks, false leads, and victories on the front lines of brain research. Weiner also offers unique insight by exploring the experiences of the brave patients and families who make cutting-edge clinical trials possible. Both a clear-eyed assessment of where the science stands and a gripping and poignant narrative of the dramatic pursuit for a cure, The Brain Under Siege is a must-read for patients, families, and anyone interested in unraveling the mysteries of the brain.

"Mechanisms of Neuroinflammation" book explains how the neuronal cells become swollen at the moment of the blood-brain barrier disruption and how they lose their immunological isolation. A cascade of cytokines and immune cells from the bloodstream enters the nervous system, inflaming neurons and activating the glia. This produces a neuroinflammatory process that can generate different neurodegenerative diseases. Better understanding of mechanisms that are activated at the time when the damage to the brain occurs could lead to the development of suitable therapies that revert the neuronal inflammation and thus prevent further damage to the nervous system.

Mechanisms of brain-immune interactions became a cutting-edge topic in systemic neurosciences over the past years. Acute lesions of the brain parenchyma, particularly, induce a profound and highly complex neuroinflammatory reaction with similar mechanistic properties between differing disease paradigms like ischemic stroke, intracerebral hemorrhage (ICH) and traumatic brain injury (TBI). Resident microglial cells sense tissue damage and initiate inflammation, activation of the endothelial brain-immune interface promotes recruitment of systemic immune cells to the brain and systemic humoral immune mediators (e.g. complements and cytokines) enter the brain through the damaged blood-brain barrier. These cellular and humoral constituents of the neuroinflammatory reaction to brain injury contribute substantially to secondary brain damage and neurodegeneration. Diverse inflammatory cascades such as pro-inflammatory cytokine secretion of invading leukocytes and direct cell-cell-contact cytotoxicity between lymphocytes and neurons have been demonstrated to mediate the inflammatory ‘collateral damage’ in models of acute brain injury. Besides mediating neuronal cell loss and degeneration, secondary inflammatory mechanisms also contribute to functional modulation of neurons and the impact of post-lesional neuroinflammation can even be detected on the behavioral level. The contribution of several specific immune cell subpopulations to the complex orchestration of secondary neuroinflammation has been revealed just recently. However, the differential vulnerability of specific neuronal cell types and the molecular mechanisms of inflammatory neurodegeneration are still elusive. Furthermore, we are only on the verge of characterizing the control of long-term recovery and neuronal plasticity after brain damage by inflammatory pathways. Yet, a more detailed but also comprehensive understanding of the multifaceted interaction of these two supersystems is of direct translational relevance. Immunotherapeutic strategies currently shift to the center of translational research in acute CNS lesion since all clinical trials investigating direct neuroprotective therapies failed. To advance our knowledge on brain-immune communications after brain damage an interdisciplinary approach covered by cellular neuroscience as well as neuroimmunology, brain imaging and behavioral sciences is crucial to thoroughly depict the intricate mechanisms.

Impairment of energy metabolism is a hallmark of brain aging and several neurodegenerative diseases, such as the Alzheimer’s disease (AD). Age- and disease-related hypometabolism is commonly associated with oxidative stress and they are both regarded as major contributors to the decline in synaptic plasticity and cognition. Neuroinflammatory changes, entailing microglial activation and elevated expression of inflammatory cytokines, also correlate with age-related cognitive decline. It is still under debate whether the mitochondrial dysfunction-induced metabolic deficits or the microglia activation-mediated neuroinflammation is the initiator of the cognitive changes in aging and AD. Nevertheless, multiple lines of evidence support the notion that mitochondrial dysfunction and chronic inflammation exacerbate each other, and these mechanistic diversities have cellular redox dysregulation as a common denominator. This research topic focuses on the role of a metabolic-inflammatory axis encompassing the bioenergetic activity, brain inflammatory responses and their redox regulation in healthy brain aging and neurodegenerative diseases. Dynamic interactions among these systems are reviewed in terms of their causative or in-tandem occurrence and how the systemic environment, –e.g., insulin resistance, diabetes, and systemic inflammation–, impacts on brain function.

Neuroinflammation is a burgeoning area of interest in academia and biopharma, with a broadly acknowledged role in many central nervous system (CNS) disorders. However, there is little agreement on the pathophysiological mechanisms that underlie the manifestations of neuroinflammation in the CNS compartment and how neuroinflammation operates as a driver and also as a consequence of disease in the brain. Moreover, another unclear area is how to translate increased understanding of the mechanisms that underlie neuroinflammation and its manifestations in the CNS to therapeutics. To address these gaps in understanding mechanisms and how to translate that understanding into therapeutics, the Forum on Neuroscience and Nervous System Disorders of the National Academies of Sciences, Engineering, and Medicine convened a workshop on March 20-21, 2017, bringing together key leaders in the field from industry, academia, and governmental agencies to explore the role and mechanisms of neuroinflammation in a variety of CNS diseases. The workshop also considered strategies to advance the identification and validation of biomarkers of neuroinflammation that could accelerate development of therapies, bringing much-needed treatments to patients with disorders ranging from neuroinflammatory diseases such as multiple sclerosis (MS) to neuropsychiatric disorders such as depression. This publication summarizes the presentations and discussions from the workshop.

This innovative, comprehensive book covers the key elements of perioperative management of older patients. The book's chapter structure coincides with the clinical path patients tread during their treatment, from preoperative evaluation to post-hospital care. Epidemiological aspects and aging processes are illustrated, providing keys to understanding the quick expansion of geriatric surgery and defining the clinical profile of older surgical patients in a cybernetic perspective. Preoperative evaluation and preparation for surgery, including medication reconciliation and pre-habilitation, are developed in the light of supporting decision-making about surgery in an evidence-based and patient-focused way. Intra- and postoperative management are discussed, aiming to tailor anesthetic, surgical and nursing approaches to specific patients' needs, in order to prevent both general and age-related complications. This volume also addresses issues relevant to geriatric surgery, from different organizational models to clinical risk management and systems engineering applied to hospital organization.
