Comparative values of CSF-cholesterol and CSF-triglycerides along with other biochemical parameters in neurological disorders.

Different parameters in CSF which are routinely investigated for the diagnosis and prognosis of neurological disorders do not provide confirmation to the type of neurological disorder. The rise in protein level in CSF was found to be nonspecific and estimation of glucose and chloride in CSF has lost its significance. Therefore, determination of concentration of CSF cholesterol and triglycerides may aid in the diagnosis of tuberculous meningitis, pyogenic meningitis, viral encephalitis and hydrocephalus. The mechanism by which the levels of CSF cholesterol end triglycerides are altered in neurological disorders is not known. The rise cholesterol and triglycerides levels in CSF may be due to increased activity of brain cells or by altered function of blood brain barrier.
