Serum concentrations of neuron-specific enolase in pediatric migraine.

Recent studies suggest that migraine might be a progressive disease that causes neuronal damage, rather than being a benign headache disorder. The objective of the present study was to investigate the concentrations of neuron-specific enolase (NSE) in pediatric migraineurs in order to identify possible neuronal damage. Forty-one children and adolescents with migraine (mean age: 14.58 +/- 2.35 years, range: 7-17 years, 12 with aura) and 30 control subjects were included. Serum NSE levels were measured during the attack and repeated at least 7 days thereafter in the patients, and measurements were obtained once in the control group. There were no significant differences in NSE concentrations with respect to values during the attack versus pain-free period or between the patient and control groups. NSE levels did not differ according to the clinical variables, including the presence of aura, severity and duration of headaches, nor with the length of migraine. In conclusion, our study showed that NSE levels did not change during migraine attack in pediatric patients. Further studies with different markers are warranted to assess possible neuronal injury in pediatric migraine.
