| dentatorubral cerebellar atrophy with polymyoclonus | A familial disorder beginning in late childhood, characterised by progressive cerebellar ataxia, action myoclonus and preserved intellect. Probably due to multiple causes, mitochondrial abnormalities being one. Synonym: dentatorubral cerebellar atrophy with polymyoclonus. (05 Mar 2000) |
| diffuse brain atrophy | A form of dementia caused by destruction (atrophy) of the frontal lobes of the brain. This condition leads to the progressive deterioration of mental functioning. Incidence: 9 in 10,000 people in the general population. (27 Sep 1997) |
| disuse atrophy | Muscle wasting caused by immobilization, such as casting. (05 Mar 2000) |
| idiopathic muscular 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) |
| infantile 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) |

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.

| olivopontocerebellar atrophy | A collection of diseases with atrophy of the cerebellum, pons, and inferior olives described in 1900 by dejerine and thomas. Signs and symptoms include ataxia of trunk and limbs, dysarthria, intention tremor, followed by generalised rigidity and dementia. (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) |
| essential progressive atrophy of iris | Progressive atrophy of the iris without inflammatory signs, characterised by patchy loss of all layers of the iris with hole formation, migration of the pupil, degeneration of the corneal endothelium, peripheral anterior synechiae, and secondary glaucoma; usually unilateral, predominantly affecting women in their middle years.
