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.
Clemastine, an antihistamine drug, has been studied for its potential to possibly promote remyelination and myelin repair in conditions like multiple sclerosis (MS). [ 21 ] [ 22 ] Early phase II clinical trials showed promise for promoting remyelination in patients with MS, with clemastine improving nerve conduction velocity in the optic nerve.
Myelin's best known function is to increase the rate at which information, encoded as electrical charges, passes along the axon's length. Myelin achieves this by eliciting saltatory conduction. [1] Saltatory conduction refers to the fact that electrical impulses 'jump' along the axon, over long myelin sheaths, from one node of Ranvier to the next.
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
Increased myelin density in humans as a result of a prolonged myelination may, therefore, structure risk for myelin degeneration and dysfunction. Evolutionary considerations for the role of prolonged cortical myelination as a risk factor for demyelinating disease are particularly pertinent given that genetics and autoimmune deficiency ...
Neuroregeneration is the regrowth or repair of nervous tissues, cells or cell products. Neuroregenerative mechanisms may include generation of new neurons , glia , axons , myelin , or synapses . Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms involved ...
A new study explains how mitochondria act as “reservoirs” to store NAD for cells to use, which could help scientists come up with NAD-boosting therapies to combat aging and age-related diseases.
While the disease is fatal, the age of onset is a key factor, as infants have a typical life expectancy of 2–8 years, while adults typically live more than a decade after onset. Treatment options are limited, although hematopoietic stem cell transplantations using bone marrow or cord blood seem to help in certain leukodystrophy types, while ...
