In spite of evident success in approaches for prevention, diagnostics and treatment during the last decades, the encephalitises of different etiology still constitute a menace for thousands of people all around the world. Recently, three-volume book was published by InTech, including the first “Flavivirus Encephalitis” (edited by Daniel Růžek), the second “Non-Flavivirus Encephalitis” (edited by Sergey Tkachev) and the third “Pathogenesis of Encephalitis” (edited by Daisuke Hayasaka) parts, which can be found on InTech site (http://www.intechopen.com). But a lot of different aspects and information were not included in these volumes so we decided to publish the additional book. The first part of this book is devoted to encephalitis clinical diagnostics and treatment. Proper diagnosis definition is an important step in encephalitis treatment so the 1st chapter considers the questions of clinical management of the patient and includes step-by-step instructions for encephalitis diagnostics. In some cases the abnormalities in encephalitis clinical course or symptoms similar to encephalitis can be observed so the physicians should pay special attention to such patients. The 2nd and 3rd chapter describe the cerebrospinal fluid abnormalities that could be seen in some cases during the viral encephalitis and the cases of spontaneous intracranial hypotension that could be erroneously taken for encephalitis. One of the important questions of any pathogen study is the epidemiology and monitoring and prediction of the epidemiological situation. Chapters 4 and 5 give the example of such monitoring of the encephalitis cases caused by viral pathogens in Japan and Nepal. The members of different virus species are known to be the causative agents of encephalitis, so the second part of the book is devoted to viral pathogens, their epidemiology, pathology and diagnostics. Probably, the arboviruses (and especially members of the genus Flavivirus) are known to be one of the most known and frequent causative agents of encephalitis, so the following chapters are about arboviruses-induced encephalitises. The short review on causative agents of arboviral encephalitis is presented in Chapter 6. Chapters 7-12 are devoted to flaviviruses, their epidemiology, pathology and vaccine design. The attention should be paid to chapter seven which presents new tick-borne encephalitis virus group that was demonstrated to cause focal forms of tick-borne encephalitis with lethal outcome and has high pathogenic potential. Other virus species are also known to be the causative agents of encephalitis, so the last chapters are devoted to non-arbovirus pathogens. Chapter 13 describes the fatal case of Lissavirus encephalitis on the Russian Far-East. The detailed characteristics of the genetic, biological and pathological properties of isolated virus strain were determined. Chapter 14 is devoted to issues of pathogenesis of encephalitis caused by measles virus. The last chapter of the book focuses on encephalitis caused by enteroviruses which (especially Enterovirus71 (EV71)) have been documented to cause epidemics. The authors and editors of the book hope that this work might increase the interest in this field of research and that the readers will find it useful for their investigations and clinical usage. Also I would like to thank my family, parents and colleagues who gave me a lot of support during the work on this book.
