| optic atrophy, hereditary | An inherited disorder in which optic atrophy is associated with muscle weakness, peroneal muscular atrophy and, in some patients, lancinating pains. In these patients the peripheral sensory neurons are probably affected. (12 Dec 1998) |

| traction atrophy | Bands of thin wrinkled skin, initially red but becoming purple and white, which occur commonly on the abdomen, buttocks, and thighs at puberty and/or during and following pregnancy, and result from atrophy of the dermis and overextension of the skin; also associated with ascites and Cushing's syndrome. Synonym: atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria, striae atrophicae, striate atrophy of skin, traction atrophy, vergeture. (05 Mar 2000) |
| transneuronal atrophy | An atrophy of nerve cells following damage to the axons that make synaptic connection with them; noted especially in the lateral geniculate body. Synonym: transneuronal atrophy, transsynaptic chromatolysis. (05 Mar 2000) |
| Erb atrophy | A form of progressive muscular atrophy in which the disease begins in the muscle and not in the spinal centres. Synonym: Erb atrophy, idiopathic muscular atrophy. (05 Mar 2000) |
| trophoneurotic atrophy | Abnormalities of the skin, hair, nails, subcutaneous tissues and bone, caused by peripheral nerve lesions. Synonym: neuritic atrophy, neurogenic atrophy, neurotrophic atrophy, trophic changes. (05 Mar 2000) |
| exhaustion atrophy | Atrophy, especially of glandular cells, believed to result from excessive functional activity or overstimulation. (05 Mar 2000) |
| juvenile muscular atrophy | Slowly progressive proximal muscular weakness and wasting, beginning in childhood, caused by degeneration of motor neurons in the anterior horns of the spinal cord; onset usually between 2 and 17 years of age; usually autosomal recessive inheritance. Synonym: juvenile muscular atrophy, Kugelberg-Welander disease, Wohlfart-Kugelberg-Welander disease. (05 Mar 2000) |
| juvenile spinal muscular atrophy | Slowly progressive proximal muscular weakness and wasting, beginning in childhood, caused by degeneration of motor neurons in the anterior horns of the spinal cord; onset usually between 2 and 17 years of age; usually autosomal recessive inheritance. Synonym: juvenile muscular atrophy, Kugelberg-Welander disease, Wohlfart-Kugelberg-Welander disease. (05 Mar 2000) |
| facioscapulohumeral atrophy | A relatively benign type of muscular dystrophy commencing in childhood and slowly progressive; characterised by wasting and weakness, sometimes asymmetrical, mainly of the muscles of the face, shoulder girdle, and arms; autosomal dominant inheritance. Synonym: facioscapulohumeral atrophy, Landouzy-Dejerine dystrophy. (05 Mar 2000) |
| yellow atrophy of the liver | See: acute yellow atrophy of the liver. (05 Mar 2000) |
| familial spinal muscular atrophy | Transmitted as autosomal recessive on chromosome 5q. Progressive dysfunction of the anterior horn cells in the spinal cord and brainstem cranial nerves with profound weakness and bulbar dysfunction occurring in the first two years of life. Three groups, based on age of clinical onset, are recognised. Synonym: familial spinal muscular atrophy, Hoffmann's muscular atrophy, infantile muscular atrophy, infantile progressive spinal muscular atrophy, progressive infantile spinal muscular atrophy, Werdnig-Hoffmann disease, Werdnig-Hoffmann muscular atrophy. (05 Mar 2000) |
| Kienbock's atrophy | Acute atrophy of bone in an extremity following inflammation. (05 Mar 2000) |
| fatty atrophy | Fatty infiltration secondary to an atrophy of the essential elements of an organ or tissue. (05 Mar 2000) |
| Zimmerlin's atrophy | A variety of hereditary progressive muscular atrophy in which the atrophy begins in the upper half of the body. (05 Mar 2000) |
| Leber's hereditary optic atrophy | Hereditary degeneration of the optic nerve and papillomacular bundle with resulting rapid loss of central vision, progressive for several weeks, then usually stationary with permanent central scotoma; age of onset is variable, most often in the third decade; more males than females are affected and transmission is cytoplasmic and strictly on the female side. Mutation on the mitochondrial chromosome involved, which presumably interacts with an X-linked mutant. This mechanism may explain the bizarre sex ratio, which differs significantly from one country to another. (05 Mar 2000) |
