NEURON-SPECIFIC ENOLASE IN PATIENTS WITH ACUTE ISCHEMIC STROKE AND RELATED DEMENTIA

Neuron-specific enolase (NSE) levels of cerebrospinal fluid (CSF) were measured in 39 patients with ischemic stroke and 15 controls. There was a significant increase of CSF NSE in acute ischemic stroke patients as compared with the controls. The altered CSF NSE levels correlated well with the infarct size in CT scan. The CSF NSE levels were higher in 6-multiinfarct dementia (MID) patients who were diagnosed after 6-month follow-up than those in 22 non-MID patients of this series. Our research supports the view that CSF NSE can be a useful biochemical marker for brain ischemia. The importance of CSF NSE in the study of dementia related to ischemic stroke is worth further studies.
