EVALUATION OF BLOOD PARAMETERS IN ATTENTİON DEFICIT HYPERACTIVITY DISORDER

Abstract

Objective: Attention deficit hyperactivity disorder (ADHD) is a neuropsychiatric disorder that is common in the paediatric age group. Although some studies have been conducted on this purpose, the etiology has not been fully elucidated. We aimed to contribute on literature about the disease through investigating some blood parameters at pediatric ADHD patients. Methods: The study included 91 children and 115 healthy children between the ages of 5 and 15 years. Serum iron, total iron binding capacity, ferritin, vitamin B12 level, folic acid level, free T4 and thyroid stimulating hormone levels were studied in whole group. Results: The mean age of the patient group was 9.0 +/- 2.5 years, the mean age of the control group was 9.7 +/- 3.1 years, and there was no difference between them. Male sex ratio was higher in both groups. Significant changes were detected in MCV, RDW, neutrophil count, MPV, plateletcrit (PCT), platelet distribution width (PDW) results between control and experimental groups. Serum iron level was significantly lower in the control group comparing to the patient group. There was no statistical difference between the groups regarding ferritin values. When the results of vitamin B12, folic acid and thyroid function tests were evaluated, no statistically significant difference was found between the groups. Conclusion: Further studies which involve larger population are essential to confirm the results that our findings to be find meaningful.
