| paroxysmal cerebral dysrhythmia | A diffusely abnormal electroencephalogram often seen with epilepsy. (05 Mar 2000) |
|---|---|
| medial cerebral surface | It faces, above as well as anterior and posterior to the corpus callosum, the falx cerebri; below it are the mesencephalon and the dura-covered medial wall of the middle cranial fossa. Synonym: facies medialis cerebri, medial cerebral surface. (05 Mar 2000) |
| medial surface of cerebral hemisphere | It faces, above as well as anterior and posterior to the corpus callosum, the falx cerebri; below it are the mesencephalon and the dura-covered medial wall of the middle cranial fossa. Synonym: facies medialis cerebri, medial cerebral surface. (05 Mar 2000) |
| cerebral | <anatomy> Of or pertaining of the cerebrum or the brain. (18 Nov 1997) |
| cerebral agraphia | The inability to express ideas in writing. Synonym: mental agraphia. (05 Mar 2000) |
| cerebral amyloid angiopathy | <pathology> A condition where there is a deposition of amyloid (insoluble protein) in the walls of the arteries which supply the brain. This results in an increased risk of dementia and-or intracerebral haemorrhage. Cerebral amyloidosis or cerebral amyloid angiopathy, is a complication of primary amyloidosis. Origin: Gr. Pathos = disease (27 Sep 1997) |

| cerebral aneurysm | A dilated and weakened portion of a cerebral blood vessel that is prone to rupture. A cerebral aneurysm may occur as a birth defect or develop as the result of long-standing poorly controlled hypertension. Symptoms of a ruptured cerebral aneurysm include a sudden, severe thunderclap headache that may be associated with nausea, vomiting and a decreased level of consciousness. (27 Sep 1997) |
| cerebral angiography | Radiography of the vascular system of the brain after injection of a contrast medium. (12 Dec 1998) |
| cerebral anoxia | A reduced supply of oxygen to the brain. (12 Dec 1998) |
| cerebral anthrax | A form of anthrax, associated with pulmonary or intestinal anthrax, in which the specific bacilli invade the capillaries of the brain causing violent delirium; frequently associated with haemorrhagic meningitis. (05 Mar 2000) |
| cerebral aqueduct | An ependymal-lined canal in the mesencephalon about 20 mm long, connecting the third to the fourth ventricle. Synonym: aqueductus cerebri, aqueduct of cerebrum, aqueductus sylvii, iter a tertio ad quartum ventriculum, sylvian aqueduct. (05 Mar 2000) |
| cerebral arteries | The arteries supplying the cerebral cortex. (12 Dec 1998) |
| cerebral arteriography | Radiography of the vascular system of the brain after injection of a contrast medium. (12 Dec 1998) |
| cerebral arteriovenous malformations | Vascular anomalies in which tangles of arteries are connected directly to veins without intervening capillaries. The resulting vessels are thin-walled owing to poorly developed elastic and muscle tissue within the media. They can be located anywhere in the brain and can produce headaches, seizures, focal neurologic deficits, or intracranial haemorrhage. Familial cases are rare, indicating that the problem reflects sporadic abnormalities in embryologic development. (12 Dec 1998) |
