| nodular sclerosis | <cardiology, pathology> The progressive narrowing and hardening of the arteries over time. This is known to occur to some degree with aging, but other risk factors that accelerate this process have been identified. These factors include: high cholesterol, high blood pressure, smoking, diabetes and family history for atherosclerotic disease. (27 Sep 1997) |

| nuclear sclerosis | Increased refractivity of the central portion of the lens of the eye. See: nuclear cataract. (05 Mar 2000) |
| systemic sclerosis | <rheumatology> A multisystem disorder of unknown aetiology. It is characterised by fibrosis (scarring) of the skin, blood vessels and internal organs. Involvement of the gastrointestinal tract, heart, kidneys and lungs is common. (09 Jan 1998) |
| disseminated sclerosis | <neurology> Neurodegenerative disease characterised by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in 3rd or 4th decade with intermittent progression over an extended period. Cause still uncertain. (18 Nov 1997) |
| idiopathic hypercalcaemic sclerosis of infants | See: idiopathic hypercalcaemia of infants. (05 Mar 2000) |
| insular sclerosis | <neurology> Neurodegenerative disease characterised by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in 3rd or 4th decade with intermittent progression over an extended period. Cause still uncertain. (18 Nov 1997) |
| ovulational sclerosis | A slowly progressive sclerosis in the walls of the ovarian arteries which commences after puberty. Synonym: menstrual sclerosis, ovulational sclerosis. (05 Mar 2000) |
| endocardial sclerosis | <radiology> Unknown aetiology, diffuse thickening of endocardium, few live more than 2 yrs, limited to left chambers in 80%, causes restrictive cardiomyopathy (12 Dec 1998) |
| tuberous sclerosis | <radiology> (Bourneville disease) autosomal dominant phakomatosis classic triad: seizures, retardation, adenoma sebaceum, calcified subependymal hamartomas, uncalcified tubers in cerebral cortex, enhancing lesion most likely to be malignant transformation to giant cell astrocytoma associated with: skin lesions, angiomyolipoma, increased risk of renal cell carcinoma (12 Dec 1998) |
| unicellular sclerosis | A growth of fibrous tissue between and isolating the individual cells of a part. (05 Mar 2000) |
| focal sclerosis | <neurology> Neurodegenerative disease characterised by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in 3rd or 4th decade with intermittent progression over an extended period. Cause still uncertain. (18 Nov 1997) |
| focal sclerosis with hyalinosis | <nephrology> A kidney disorder that results in fibrosis and scarring in the kidney glomerulus. The cause is unknown but some cases can result from reflux nephropathy. The clinical manifestation of this kidney disorder is nephrotic syndrome. Symptoms include weight gain, swelling, hypertension and foamy urine. High blood cholesterol and triglyceride levels are also seen with this disorder. Treatment has included the use of corticosteroids and immunosuppressives. Antihypertensive agents and diuretics may also be necessary. Over one-half will develop chronic renal failure within 10 years of diagnosis. (27 Sep 1997) |
| laminar cortical sclerosis | A degeneration of nerve fibres in the corona radiata in a laminar pattern. (05 Mar 2000) |
| lateral spinal sclerosis | Considered by many to be a subgroup of motor neuron disease; a slowly progressive degenerative disorder of the motor neurons of the cerebral cortex, resulting in widespread weakness on an upper motor neuron basis; spasticity, hyperreflexia, and Babinski signs are present, but not fasciculation potentials, nor any electrodiagnostic evidence of a lower motor neuron lesion. Synonym: lateral spinal sclerosis. (05 Mar 2000) |
| lobar sclerosis | Circumscribed atrophy of the cerebral cortex. Synonym: lobar sclerosis, progressive circumscribed cerebral atrophy. (05 Mar 2000) |
