Medical Definition of Neuroaxonal dystrophies
1. Encephalopathies characterised by swelling in distal portions of axons (speroids) often with axonal degeneration. Neuroaxonal dystrophy is seen in various genetic diseases, vitamin deficiencies, and aging. Infantile neuroaxonal dystrophy (seitelberger's disease) is an autosomal recessive trait characterised by arrested psychomotor development at 6 months to 2 years followed by ataxia, brainstem signs, optic atrophy, and quadriparesis. Hallervorden-spatz syndrome, which usually first appears at 7 to 12 years of age, may be genetically related to the infantile syndrome. (12 Dec 1998)
