In this study, we aimed to investigate the etiological factors, electroencephalographic (EEG) findings, rates of response to iron therapy, and factors affecting response to iron therapy in children diagnosed with breath-holding spells (BHS). Methods: The study included 136 children aged 1 to 48 months who received iron therapy after a BHS diagnosis at our pediatric neurology clinic between November 2015 and November 2019. Patient medical records (physical examination, laboratory and EEG findings, medical history, and effectiveness of iron therapy) were reviewed retrospectively. Results: Of all patents, 81 (59.6%) exhibited partial response (partial remission) to iron therapy (50% decrease in BHS frequency), 52 (39%) responded completely (complete remission), and 2 were unresponsive. Comparison of the patients with complete and partial remission revealed a higher rate of complete remission in girls. In addition, patients with complete remission had higher levels of hemoglobin, MCV, and ferritin than those with partial remission. Complete remission rates were also higher in patients with normal EEG findings. Conclusion: BHS in childhood is a benign, recurring, and non-epileptic disorder and its differentiation from epilepsy is important. Children with BHS respond well to iron therapy, which can be recommended even if the serum iron and ferritin levels are normal.
