Neuron-specific enolase (NSE) is a neuronal glycolytic enzyme of which cerebrospinal fluid (CSF) levels are found altered following acute or prolonged neuronal damage. Investigations concerning the role of NSE in Alzheimer's disease (AD) are conflicting with both elevated and reduced levels. We measured CSF-levels of NSE in 32 patients with AD and 32 healthy subjects (HS) using an electrochemiluminescence immunoassay (ECLIA). Mean levels of adjusted NSE were significantly elevated in AD (18.12 ng/mL (95% CI 15.63-20.60), HS 8.46 ng/mL (95% CI 5.98-10.94), p = 0.00002) and effect size for mean group differences high (1.84). NSE alone (cut-off score 15.80 ng/mL, 94% sensitivity, 97% specificity) and in combination with T-tau and P-Tau had high diagnostic accuracy to differentiate AD from HS. NSE correlated significantly with T-tau (r >= 0.87, p < 0.000001) and P-tau (r >= 0.88, p < 0.000001) in both AD and HS. Our results indicate elevated CSF-NSE levels to reflect altered neuronal metabolism in AD that may be used in supporting AD diagnostics. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
