Infections of the central nervous system (CNS) consist of infections primarily of the brain and spinal cord. They include mostly viral infections, less commonly bacterial infections, fungal infections, prion diseases and protozoan infections. Neonatal meningitis is a particular classification by age.
Infectious diseases are transmitted in several ways. Some of these infections may affect the brain or spinal cord directly. Generally, an infection is a disease that is caused by the invasion of a microorganism or virus.
The CNS viral diseases are caused by viruses that attack the CNS. Existing and emerging viral CNS infections are major sources of human morbidity and mortality. Virus infections usually begin in the peripheral tissues, and can invade the mammalian system by spreading into the peripheral nervous system and more rarely the CNS.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e ...
The immune response may affect the brain and spinal cord through inflammation and necrosis of small blood vessels. In tertiary syphilis, reactivation of a chronic latent infection causes severe inflammation of CNS arteries called endarteritis obliterans , leading to meningovascular syphilis.
Pediatrics researchers find an unexplained increase in brain abscesses in kids and teens in Nevada. A surge in children's respiratory illnesses could be why. Brain infections in kids may be ...
Nervous system diseases, also known as nervous system or neurological disorders, refers to a small class of medical conditions affecting the nervous system.This category encompasses over 600 different conditions, including genetic disorders, infections, cancer, seizure disorders (such as epilepsy), conditions with a cardiovascular origin (such as stroke), congenital and developmental disorders ...
Brain scan, done by MRI, can determine inflammation and differentiate from other possible causes. EEG , in monitoring brain activity, encephalitis will produce abnormal signal. Lumbar puncture (spinal tap), this helps determine via a test using the cerebral-spinal fluid, obtained from the lumbar region.
