| cerebral hernia | Protrusion of brain substance through a defect in the skull. (05 Mar 2000) |

| cerebral herniation | A condition that occurs when the brain is under abnormally increased pressure. The increased intracranial pressure forces the brain downward inside the skull. This results in typical neurologic manifestations (coma, paralysis and a unilateral dilated pupil). May occur secondary to head injury, primary or metastatic brain tumour, bacterial meningitis and brain abscess. Brain herniations may involve different portions of the brain such as the cerebellum (cerebellar herniation), uncus (uncal herniation) and transtentorial herniation of the cerebrum. (27 Sep 1997) |
| cerebral hypoxia | A lack of oxygen to the cerebral hemispheres (the brain). Depending on the duration and extent of hypoxia, symptoms can be mild (for example lethargy) or serious neurologic damage can result (for example coma, seizures, death). (27 Sep 1997) |
| cerebral index | The ratio of the transverse to the anteroposterior diameter of the cranial cavity multiplied by 100. (05 Mar 2000) |
| cerebral infarction | Infarction of brain tissue. (12 Dec 1998) |
| cerebral ischemia | Deficiency in blood supply to the brain. (12 Dec 1998) |
| cerebral ischemia, transient | Nonconvulsive, reversible, focal neurologic deficits lasting minutes up to about 24 hours, resulting mainly from arteriosclerosis, emboli, or hypertensive episodes. (12 Dec 1998) |
| cerebral lacuna | A small circumscribed loss of brain tissue caused by occlusion of one of the small penetrating arteries. Synonym: lacuna cerebri. (05 Mar 2000) |
| cerebral layer of retina | The internal layer of the retina containing the neural elements, as distinguished from the outer leaf of the retina, or pigmented layer. Synonym: pars optica retinae, neural layer of retina, optic part of retina, stratum cerebrale retinae. (05 Mar 2000) |
| 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) |
