Glossary for Myelitis

  • Acute Disseminated Encephalomyelitis: A rare neurological disorder where an inflammation of the brain and spinal cord occurs due to damage to the protective covering (myelin sheath) around the nerves.
  • Arm weakness: Weakness of the muscles of the arm.
  • Back conditions: A group of conditions that affect the back
  • Back pain: Pain from the back or spine.
  • Bing-Neel syndrome: A rare disorder involving infiltration of the central nervous system by abnormal leukemia-like cells (lymphoplasmocytoid cells) that occur in Waldenström's macroglobulinemia. The abnormality increases blood viscosity which impairs its circulation through small brain and eye blood vessels.
  • Brown-Sequard Syndrome: A disorder where spinal cord compression and lesions involve only half of the spinal cord.
  • Encephalomyelitis: Inflammation of the brain and spinal cord.
  • Gnathostoma Infection: Infection with a type of round worm (Gnathostoma spinigerum and Gnathostoma hispidum). Infection typically occurs through eating undercooked fish or poultry containing the roundworm larvae or by drinking contaminated water. The symptoms are determined by which tissues the worms migrate through. The worms tend to migrate mainly through the skin.
  • HIV/AIDS: HIV is a sexually transmitted virus and AIDS is the progressive immune failure that HIV causes.
  • Herpesvirus: A group of DNA viruses that occur in humans
  • Inflammatory conditions that may be pathogenic or non-pathogenic: Medical conditions causing inflammation, whether due to a pathogen (e.g. bacteria, virus), or a systemic or other cause.
  • Leg weakness: Muscle weakness of the leg
  • Myelography: A test used to screen whole spinal cord and cauda equina for compressive or expanding lesions
  • Nervous system conditions: Diseases affecting the nerves and the nervous system.
  • Neuromyelitis Optica: A demyelinating disorder associated with transverse myelopathy and optic neuritis
  • Numbness: Loss of feeling or sensation
  • Polio: Dangerous virus now rare due to vaccination.
  • Poxviridae disease: A group of infectious diseases that cause puss filled skin eruptions. Chicken pox and small pox are examples.
  • Spinal Cord Disorders: Any condition that affects the spinal cord
  • Spinal conditions: Any condition that affects the spine
  • Syphilis: A sexually transmitted disease caused by a bacteria (Treponema pallidum). The condition is often asymptomatic in the early stages but one or more sores may be present in the early stages. Untreated syphilis usually results in remission of visible symptoms but further severe damage may occur to internal organs and other body tissues which can result in death.
  • Tingling: Tingling, prickling, or pins-and-needles sensations
  • Transverse myelitis: Inflammation of the spinal cord which results in various neurological and muscle symptoms. The inflammation can occur for no obvious reason or may result from a virus, bacterial infection, autoimmune disease or vaccination. The type and severity of symptoms is determined by the location and degree of inflammation.
