Central nervous system disease - Encephalitis

Introduction

The central nervous system is divided into two broad categories: diseases associated with abnormalities or lesions of the nervous tissues and diseases devoid of somatic signs or molecular. The first are neurological diseases, psychiatric diseases seconds. This simplistic classification necessarily induced blur the boundary between these two great families of pathology, especially since this classification is constantly changing depending on the progress of research in neurobiology. Psychiatric illness can change the category with the discovery of cellular abnormalities or gene at least partly explains its pathophysiology. Conversely, a neurological disease may develop psychiatric complications. Also, this classification 'academic' can be challenged at any time. It must be approached with some caution and without a priori dogmatic. Another way to subdivide CNS disease would define a basic psycho-cognitive rather than pathological. In this context, when thinking and / or mood of the patient is directly affected when the disease will involve psychiatric sphere, whether or not the anatomical lesions and / or genetic defects involved in the pathophysiology. Anyway these neuropsychiatric disorders are a major public health problem as evidenced by some figures: 70 million people suffer from the USA and more than a million French are treated each year for such disorders

Encephalitis is an inflammation of the brain. It is usually caused by a foreign substance or a viral infection. Symptoms of this disease include: headache, neck pain, drowsiness, nausea, and fever. If caused by the West Nile virus, it may be lethal to humans, as well as birds and horses.
