| cerebral gigantism | A syndrome characterised by increased birth weight and length (above 90th percentile), accelerated growth rate for the first 4 or 5 years without elevation of serum growth hormone levels, and then reversion to normal growth rate; characteristic facies include prognathism, hypertelorism, antimongoloid slant, and dolichocephalic skull; moderate mental retardation and impaired coordination are also associated. See: Sotos' syndrome. (05 Mar 2000) |

| cerebral haematoma | A blood clot in the brain. (27 Sep 1997) |
| cerebral haemorrhage | A sudden and abrupt bleeding into the tissue of the brain. Usually occurs as the result of a weakened artery from the effects of high blood pressure and atherosclerosis. (27 Sep 1997) |
| cerebral hemisphere | 1. A half sphere; one half of a sphere or globe, when divided by a plane passing through its center. 2. Half of the terrestrial globe, or a projection of the same in a map or picture. 3. The people who inhabit a hemisphere. "He died . . . Mourned by a hemisphere." (J. P. Peters)ten Cerebral hemispheres. <anatomy> See Brain. <physics> Magdeburg hemispheres, two hemispherical cups forming, when placed together, a cavity from which the air can be withdrawn by an air pump; used to illustrate the pressure of the air. So called because invented by Otto von Guericke at Magdeburg. Origin: L. Hemisphaerium, Gr.; half = sphere: cf. F. Hemisphere. See Hemi-, and Sphere. Source: Websters Dictionary (01 Mar 1998) |
| cerebral hemispheres | The two halves of the cerebrum, the largest part of the brain. (12 Dec 1998) |
| 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 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) |
