Insights
Iron deficiency anemia (IDA) may protect against febrile seizures (FS) in children. IDA was more prevalent in children with afebrile seizures, suggesting a potential protective role against FS.
Area of Science:
- Pediatrics
- Neurology
- Hematology
Background:
- Contradictory findings exist regarding the association between iron deficiency anemia (IDA) and febrile seizures (FS).
- Understanding this relationship is crucial for pediatric health management.
Purpose of the Study:
- To investigate the effect of IDA on the occurrence of FS in children.
- To clarify the association between IDA and different seizure types in pediatric patients.
Main Methods:
- A case-control study involving 52 children with FS, 18 with afebrile seizures, and 51 with fever without seizures (ages 6 months to 5 years).
- Blood parameters including hemoglobin, hematocrit, ferritin, and red blood cell indices were measured.
- Statistical analysis was performed to compare IDA prevalence and seizure risk.
Main Results:
- IDA prevalence was 34.6% in the FS group, 66.7% in the afebrile seizure group, and 41.2% in the fever without seizure group; no statistically significant difference was found between groups.
- Children with FS had higher hemoglobin, hematocrit, and RBC levels, and lower MCV, MCH, and MCHC levels compared to controls.
- The odds ratio for FS compared to febrile group was 0.756 (p=0.493), and compared to seizure group was 0.265 (p=0.022).
Conclusions:
- IDA may exert a protective effect against the onset of febrile seizures in children.
- IDA appears to be more common in children experiencing afebrile seizures.
- Further extensive research is recommended to confirm these findings.
Objective:
Different studies have reported contradictory results regarding the relationship between iron deficiency anemia (IDA) and febrile seizure (FS). The present study was conducted to determine the effect of IDA on FS in children.
Patients And Methods:
This case-control study was conducted among 52 children with FS (the case group) and 18 children with afebrile seizures and 51 children with fever without seizures in the age range of 6 months to 5 years admitted to the pediatric ward of Imam Khomeini Hospital in Ilam from March 2016 to January 2017. Patients were selected using the convenience sampling method. Red blood cell (RBC) count as well as measurement of hemoglobin (Hb), hematocrit (Hct), ferritin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) levels were performed in all patients. The collected data were analyzed using SPSS16 software.
Results:
A total of 34.6% in the FS group, 66.7% in the afebrile seizure group and 41.2% in the fever without seizure group suffered from IDA, which was not statistically significant between the three groups. Hb, Hct and RBC levels were higher in the case group and MCV, MCH, MCHC levels in the case group were lower than those in the control group. The odds ratio (OR) for FS compared to the febrile group was 0.756 [95% confidence interval (CI) = 0.34-1.68; p = 0.493] and that for FS compared to seizure was 0.265 (95% CI = 0.085-0.823; p = 0.022).
Conclusions:
This study showed that IDA may have protective effects on the onset of FS, and based on the results, IDA is more common in children with afebrile seizures. Further and more comprehensive studies are recommended.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
