| cerebral lipidosis | Any one of a group of inherited diseases characterised by failure to thrive, hypertonicity, progressive spastic paralysis, loss of vision and occurrence of blindness, usually with macular degeneration and optic atrophy, convulsions, and mental deterioration; associated with abnormal storage of sphingomyelin and related lipids in the brain. Four types are recognised as clinically and enzymatically distinct: 1) infantile type (Tay-Sachs disease, GM2 gangliosidosis) due to a deficiency of hexosaminidase A; 2) early juvenile type (Jansky-Bielschowsky or Bielschowsky's disease); 3) late juvenile type (Spielmeyer-Vogt disease; Spielmeyer-Sjogren disease; Batten-Mayou disease; ceroid lipofuscinosis); and 4) adult type (Kufs disease). Synonym: cerebral lipidosis. (05 Mar 2000) |
|---|---|
| cerebral localization | The mapping of the cerebral cortex into areas and the correlation of the various areas with cerebral function, or determining the site of a brain lesion, based on the signs and symptoms manifested by the patient or by neuroimaging. (05 Mar 2000) |
| cerebral malaria | A form of falciparum malaria characterised by cerebral involvement, with extreme hyperthermia and headache, and a case fatality rate of about 50%. (05 Mar 2000) |
| cerebral oedema | Brain swelling due to increased volume of the extravascular compartment from the uptake of water in the neuropile and white matter. See: brain swelling. Synonym: brain oedema. (05 Mar 2000) |
| cerebral palsy | A persisting qualitative motor disorder appearing before the age of three years, due to nonprogressive damage to the brain. (12 Dec 1998) |
| cerebral part of arachnoid | That portion of the arachnoid which lies within the cranial cavity and surrounds the brain and the cranial portion of the subarachnoid space. In several sites it is relatively widely-separated from the pia mater, creating the cranial subarachnoid cisterns. Synonym: arachnoid mater cranialis, arachnoid mater encephali, cerebral part of arachnoid. (05 Mar 2000) |
| cerebral part of dura mater | The intracranial dura mater, consisting of two layers: the outer periosteal layer which normally always adheres to the periosteum of the bones of the cranial vault; and the inner meningeal layer which in most places is fused with the outer. The two layers separate to accommodate meningeal vessels and large venous (dural) sinuses. The meningeal layer is also involved in the formation of the various dural folds, such as the falx cerebri and tentorium cerebelli and is comparable to and continuous with the dural mater of the spinal cord. The cranial epidural space is then a potential space between the bone and the combined periosteum/periosteal layer of the dura mater realised only pathologically and is neither continuous with or comparable to the vertebral epidural space. Synonym: dura mater cranialis, dura mater encephali, cerebral part of dura mater, cranial epidural space. (05 Mar 2000) |
| cerebral peduncle | Originally denoting either of the two halves of the midbrain (a relatively narrow "neck" connecting the forebrain to the hindbrain); this term has been variably used to designate only those large bundles of corticofugal fibres forming the crus cerebri, or to designate the crus cerebri plus the midbrain tegmentum; this latter more inclusive usage (crus cerebri and midbrain tegmentum) is preferred; the substantia nigra, while a part of the base of the peduncle (basis pedunculi), is considered a structure separating the midbrain tegmentum from the crus cerebri. See: crus cerebri. Synonym: pedunculus cerebri. (05 Mar 2000) |
| cerebral porosis | A porous condition of the brain caused by postmortem growth of Clostridium perfringens or other gas-forming organisms in the tissue. (05 Mar 2000) |
| cerebral revascularization | Microsurgical revascularization to improve intracranial circulation. It usually involves joining the extracranial circulation to the intracranial circulation but may include extracranial revascularization (e.g., subclavian-vertebral artery bypass, subclavian-external carotid artery bypass). It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularised tissue to the surface of the brain. (12 Dec 1998) |
| cerebral rheumatism | Central nervous system symptoms resulting from a rheumatic disease. Formerly seen primarily as a manifestation of rheumatic fever, now seen less frequently as a part of other diseases such as systemic lupus erythematosus. See: Sydenham's chorea. (05 Mar 2000) |
| cerebral sclerosis, diffuse | Diffuse progressive degeneration of the white matter of the brain, accompanied by mental deterioration, severe motor disturbances, and early death. (12 Dec 1998) |
| cerebral sinuses | Endothelium-lined venous channels in the dura mater. Synonym: sinus durae matris, cerebral sinuses, cranial sinuses, sinuses of dura mater, venous sinuses. (05 Mar 2000) |
| cerebral sphingolipidosis | Any one of a group of inherited diseases characterised by failure to thrive, hypertonicity, progressive spastic paralysis, loss of vision and occurrence of blindness, usually with macular degeneration and optic atrophy, convulsions, and mental deterioration; associated with abnormal storage of sphingomyelin and related lipids in the brain. Four types are recognised as clinically and enzymatically distinct: 1) infantile type (Tay-Sachs disease, GM2 gangliosidosis) due to a deficiency of hexosaminidase A; 2) early juvenile type (Jansky-Bielschowsky or Bielschowsky's disease); 3) late juvenile type (Spielmeyer-Vogt disease; Spielmeyer-Sjogren disease; Batten-Mayou disease; ceroid lipofuscinosis); and 4) adult type (Kufs disease). Synonym: cerebral lipidosis. (05 Mar 2000) |
| cerebral sulci | The grooves between the cerebral gyri or convolutions. Synonym: sulci cerebri. (05 Mar 2000) |
