Natural History Study of Inflammatory and Infectious Diseases of the Nervous System
National Institute of Neurological Disorders and Stroke (NINDS)
Summary
Background: \- Inflammation is how the body reacts to infection or injury. Infections or inflammation in the brain and nerves can be serious. There aren t always good tests to detect this. Researchers want to learn more about how diseases affect the brain and nerves to develop better tests and treatments. Objective: \- To learn more about how inflammation and infections hurt the brain and nervous system. Eligibility: \- People at least 2 years old with a diagnosis or suspected diagnosis of nervous system infection or inflammation. Design: * For some participants, a clinician outside of NIH will collect blood, tissue, and other samples. These will be sent to NIH and analyzed. * Other participants will have several visits to NIH. Children may not have all these tests. * Participants will have: * Medical history. * Physical and neurological exam. * Blood and urine samples collected. * Saliva collected. They will chew on a piece of sterile cotton for one minute. * Magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will get a contrast agent through an intravenous (IV) catheter during the MRI. A needle will be used to guide a thin plastic tube (catheter) into an arm vein. * Lumbar puncture. Skin will be numbed and a needle will be inserted into the space between the bones in the back. Fluid will be removed. * Some participants may have optional study procedures. These may include eye tests, memory and thinking testing, tests with electrodes on the head, or skin biopsy.
Description
Objective: The objective of this study is to examine the natural course of infectious and inflammatory diseases of the nervous system, to identify causative or associated pathogens when unknown, and generally to better understand the underlying immunological, genetic and pathophysiologic mechanisms that cause and contribute to these diseases and their ultimate neurological outcomes. Study Population: The study population will be patients at least 2 years old with known or suspected infection or inflammation of the nervous system and family members. Participants will be recruited through ref…

* INCLUSION CRITERIA: At the time of enrollment, participants will: 1. Have a known or suspected infection or inflammation of the nervous system or post infection sequelae based on clinical or imaging data provided by the referral facility. For the purpose of this study, neuroinfectious disease or neuroinflammation is defined as any of the following: 1. fever with nervous system signs or symptoms (excluding delirium) 2. any neurological symptoms accompanied by cerebrospinal fluid (CSF) with evidence of inflammation (which may include pleocytosis, hypoglycorrachia, elevated protein, or…
