Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid ...
CSF glucose levels can be useful in distinguishing among causes of meningitis as more than 50% of patients with bacterial meningitis have decreased CSF glucose levels while patients with viral meningitis usually have normal CSF glucose levels. Decrease in glucose levels during a CNS infection is caused due to glycolysis by both white cells and ...
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
[21] [22] Downstream of the glymphatic system's waste clearance from the ISF to the CSF, the meningeal lymphatic system drains fluid from the glymphatic system to the meningeal compartment and deep cervical lymph nodes; this is shown by the draining of fluorescent dyes injected intracisternally into the CSF in mice. [21]
In a mouse study, researchers found that zolpidem (Ambien), a common sleep aid, could prevent the brain from effectively clearing up 'waste', though it remains unclear whether this could affect ...
Clinical significance [ edit ] Age-related degenerative changes of the granulations and consequent decreased CSF resorption may underlie normal pressure hydrocephalus (which may in turn be pathogenetically implicated in additional age-related neurodegenerative disorders.
The cerebrospinal fluid (CSF) within the skull and spine provides further protection and also buoyancy, and is found in the subarachnoid space between the pia mater and the arachnoid mater. [citation needed] The CSF that is produced in the ventricular system is also necessary for chemical stability, and the provision of nutrients needed by the ...
Oligoclonal bands are present in the CSF of more than 95% of patients with clinically definite multiple sclerosis. [ 1 ] Two methods of analysis are possible: (a) protein electrophoresis , a method of analyzing the composition of fluids, also known as "SDS-PAGE (sodium dodecyl sulphate polyacrylamide gel electrophoresis)/ Coomassie blue ...
