  2. Demyelinating disease - Wikipedia

    en.wikipedia.org/wiki/Demyelinating_disease

    Exclusion of other conditions that have overlapping symptoms [13] Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. This method is reliable because ...

    en.wikipedia.org/wiki/Inflammatory_demyelinating...

    Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.

  4. Pathophysiology of nerve entrapment - Wikipedia

    en.wikipedia.org/wiki/Pathophysiology_of_nerve...

    Nerves may be myelinated or unmyelinated. Myelinated nerves have the axon covered by segments of schwann cells, which are short and concentrically wrapped around the diameter of an axon to give the appearance of a sausage-like mass and called a myelin sheath. The schwann cells are arranged in pattern such all parts of the axon are wrapped in ...

    Under laboratory conditions, stem cells are quite capable of proliferating and differentiating into remyelinating oligodendrocytes; it is therefore suspected that inflammatory conditions or axonal damage somehow inhibit stem cell proliferation and differentiation in affected areas [55] It is possible to predict how much and when lesion will ...

  6. Chronic inflammatory demyelinating polyneuropathy - Wikipedia

    Problems with gripping objects, tying shoe laces, and using utensils can all be brought on by upper limb involvement. Proximal limb weakness is a fundamental clinical characteristic that sets apart chronic inflammatory demyelinating polyneuropathy from the vast majority of distal polyneuropathies , which are far more common.

  7. Myelitis - Wikipedia

    en.wikipedia.org/wiki/Myelitis

    Myelitis is inflammation of the spinal cord which can disrupt the normal responses from the brain to the rest of the body, and from the rest of the body to the brain. . Inflammation in the spinal cord can cause the myelin and axon to be damaged resulting in symptoms such as paralysis and sen

  8. Myelin - Wikipedia

    en.wikipedia.org/wiki/Myelin

    In the central nervous system (brain, spinal cord and optic nerves), myelination is formed by specialized glial cells called oligodendrocytes, each of which sends out processes (limb-like extensions from the cell body) to myelinate multiple nearby axons; while in the peripheral nervous system, myelin is formed by Schwann cells (neurolemmocytes ...

  9. Small fiber neuropathy - Wikipedia

    en.wikipedia.org/wiki/Small_fiber_neuropathy

    Small fiber neuropathy is a condition characterized by severe pain. Symptoms typically begin in the feet or hands but can start in other parts of the body. Some people initially experience a more generalized, whole-body pain. The pain is often described as stabbing or burning, or abnormal skin sensations such as tingling or itchiness. In some ...
