However, elevated blood sugar levels (hyperglycemia) result in elevated CSF glucose levels [3] as the CSF glucose level is proportional to the blood glucose level with glucose being actively transported as well as simply diffusing down the concentration gradient from blood to CSF. In addition, damage to small blood vessels during lumbar ...
Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases , such as pseudomigraine, Susac's syndrome, and encephalitis.
A rare metabolic disease of the blood-brain glucose transport system has been described in which severe neuroglycopenic effects occurred despite normal blood glucose levels. Low levels of glucose were discovered in the cerebrospinal fluid (CSF), a condition referred to as hypoglycorrhachia [or hypoglycorrhacia]. Hypoglycorrhachia is associated ...
GLUT1 deficiency is diagnosed based on the clinical features in combination with determining the glucose concentration in the CSF and/or a genetic analysis through a lumbar puncture (spinal tap). [13] A low glucose value in CSF (<2.2 mmol/L) or lowered CSF/plasma glucose ratio (<0.4)are indicatieve of
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]

All forms of glycine encephalopathy show elevated levels of glycine in the plasma, as well as in cerebral spinal fluid (CSF). [ 1 ] : 793 Glycine concentrations in the CSF of affected patients are typically more markedly elevated than in plasma, leading to a corresponding elevation in the ratio of glycine concentrations in the cerebral spinal ...
A ratio ≤0.4 is indicative of bacterial meningitis; [52] in the newborn, glucose levels in CSF are normally higher, and a ratio below 0.6 (60%) is therefore considered abnormal. [8] High levels of lactate in CSF indicate a higher likelihood of bacterial meningitis, as does a higher white blood cell count. [52] If lactate levels are less than ...
