II. Increased CSF Glucose

  1. Reflects serum Hyperglycemia
  2. CSF Glucose lags Serum Glucose by 2 to 4 hours
  3. CSF Glucose is two thirds of Serum Glucose
  4. CSF Glucose does not usually rise above 300 mg/dl

III. Decreased CSF Glucose (Hypoglycorrhachia)

  1. Hypoglycemia
  2. Granulomatous process
    1. Bacterial Tuberculosis
    2. Sarcoidosis
  3. Chemical Meningitis
  4. Bacterial Meningitis (protein normal in 50% of cases)
  5. Fungal Meningitis
  6. Subarachnoid Hemorrhage
  7. Neoplasm
  8. Certain CNS viral infections
    1. Herpes Simplex Virus
    2. Mumps
    3. Lymphocytic choriomeningitis
