573 Possible Causes for Defective Myelination

  • Neonatal Adrenoleukodystrophy

    Most peroxisomal disorders cause severe neurological dysfunction due to CNS malformations (migration defects), myelin abnormalities, and neuronal degeneration.[neuropathology-web.org] Adrenoleukodystrophy Related Terms Adrenal gland, ALD, brain defects, leukodystrophies, Lorenzo's oil, muscle defects, myelin sheath, very long chain fatty acids, VLCFA, X[livingnaturallyonline.com]

  • Vitamin B12 Deficiency

    VB12D causes perivascular degeneration and myelin degeneration.[doi.org] VB12D also results defects in the methylation processes resulting in neuropsychiatric symptoms. 2 In conclusion, VB12D can cause FTD-like dementia even in young individuals[doi.org]

  • Anemia

    Elevated MMA results in abnormal odd chain and branched chain fatty acids with subsequent abnormal myelination, possibly leading to defective nerve transmission.[emedicine.com] Brain MRI of infants with vitamin B-12 deficiency may show delayed myelination.[web.archive.org] SAM deficiency results in abnormal methylated phospholipids such as phosphatidylcholine, and it is linked to central myelin defects and abnormal neuronal conduction, which[emedicine.com]

  • Leukodystrophy

    The leukodystrophies are a group of disorders that are caused by genetic defects in how myelin produces or metabolizes these chemicals.[ninds.nih.gov] Dysmyelination Hypo myelination is characterised by a defective structure and function of the myelin sheath in the brain and spinal cord.[missionmassimo.com] Abstract Genetic defects in myelin formation and maintenance cause leukodystrophies, a group of white matter diseases whose mechanistic underpinnings are poorly understood[ncbi.nlm.nih.gov]

  • Pelizaeus-Merzbacher Disease

    These findings suggested defective myelin synthesis as the etiology of Pelizaeus-Merzbacher disease; comprehensive classifications of the disease are expected to include both[ncbi.nlm.nih.gov] Pelizaeus Merzbacher Disease (PMD) is an X-linked developmental defect of myelination that causes childhood chronic spastic encephalopathy.[ncbi.nlm.nih.gov] Visit for more related articles at Journal of Neurological Disorders Abstract Pelizaeus-Merzbacher disease is a rare X-linked recessive disorder regarding the defective myelin[omicsonline.org]

  • Neuropathy

    Charcot-Marie-Tooth disease comprises a vast array of defects in myelin integrity that causes progressive peripheral sensorimotor neuropathy.[ncbi.nlm.nih.gov]

  • Neurotic Disorder

  • Canavan Disease

    Consequently, CD results from defective myelin synthesis due to a deficiency in the supply of the NAA-derived acetate.[ncbi.nlm.nih.gov] Leukodystrophies are hereditary metabolic diseases in which the underlying biochemical abnormalities lead to defect of myelination.[medlink.com] Canavan disease (CD) belongs to a group of conditions known as leukodystrophies, characterized by defects in myelin, commonly known as the "white matter" in the brain.[tay-sachs.org]
