The neuron marker neuron-specific enolase was at a mean ± S.E.M. of 5,816 ± 142 pg/ml and 5,238 ± 160 pg/ml in control and FP patient NDE extracts, respectively, and 290 ± 31.4 pg/ml and 352 ± 41.8 pg/ml in control and FP patient ADE extracts. Here, ENO2 is linked to acute disseminated encephalomyelitis.
