Neurological infectious disease
The most challenging neurological disorders are viral and immune mediated disorders of the nervous system. The most common neuroimmune disorder is multiple sclerosis; and HIV is the most common viral infection of the nervous system, Nonepidemic viral infections constitute the majority of infections affecting the nervous system today. Chronic neurologic disease as a sequel to infection is a relatively new and developing area of both pediatric and adult neurology research. Chief among these disorders is the role of postinfectious brain inflammation in epileptogenesis.
