Cerebrospinal fluid: A watery fluid that is continuously produced and absorbed and that flows in the ventricles within the brain and around the surface of the brain and spinal cord. Abbreviated CSF. CSF is produced by the choroid plexus, a series of infolded blood vessels that project into the cerebral ventricles, and it is absorbed into the venous system. If production exceeds absorption, CSF pressure rises, and the result is hydrocephalus. This can also occur if the CSF pathways are obstructed, causing the fluid to accumulate. The CSF obtained during a lumbar puncture is analyzed to detect disease.
Cerebrovascular: Pertaining to the blood vessels and, especially, the arteries that supply the brain. As in cerebrovascular accident or cerebrovascular disease.
- Cerebrovascular accident
The term “stroke” reflects the belief among the ancient Greeks and Romans that someone suffering a stroke (or any sudden incapacity) had been struck down by the gods.
- Cerebrovascular disease
Cerebrovascular disease: Disease of the blood vessels and, especially, the arteries that supply the brain. Cerebrovascular disease is usually caused by atherosclerosis and can lead to a stroke. See also atherosclerosis, stroke.
- Cerebrovascular accident (CVA) prevention
In many cases, a person may have a transient ischemic attack (TIA), a neurological event with the symptoms of a stroke, but the symptoms go away within a short period of time. This is often caused by the narrowing or ulceration of the carotid arteries (the major arteries in the neck that supply blood to […]
- Cerebrovascular ferrocalcinosis
Cerebrovascular ferrocalcinosis: A condition, first described in 1930 by T. Fahr and therefore called Fahr syndrome, that is a genetic (inherited) neurological disorder characterized by abnormal deposits of calcium in certain of areas of the brain (including the basal ganglia and the cerebral cortex). Symptoms may include motor function deterioration, dementia, mental retardation, spastic paralysis, […]
