Abstract

The final diagnosis of 158 patients who had a cerebrospinal fluid (CSF) lactate concentration greater than 2 mmol/l was ascertained. The conditions included seizures, inflammatory changes, and proven metabolic disorders. For the diagnosis of congenital lactic acidoses, CSF lactate should ideally be measured in a seizure free patient after any acute illness.

  • CSF, cerebrospinal fluid
  • cerebral inflammation
  • cerebral ischaemia
  • congenital lactic acidosis
  • mitochondrial disorder
  • seizures
