Evaluation of the Relationship Between Head Trauma and Attention-Deficit/Hyperactivity Disorder in Primary School Children Admitted to the Emergency Department.

Objective: Head trauma causes a significant number of deaths as well as temporary and permanent disabilities every year. In this study, the prevalence of attention-deficit/hyperactivity disorder (ADHD) in primary school children who visited the emergency department (ED) for mild head trauma and the role of ADHD in mild head trauma of this age group were investigated.

Methods: It was performed with 134 children of primary school age (6-12 years) who were admitted to the ED with mild head trauma and 134 children (control group) who presented with complaints other than head trauma. Turgay DSM-IV-Based Child and Adolescent Behavioral Disorders Screening and Rating Scale (T-DSM-IV-S) was used to evaluate the children for suspected ADHD. According to this scale, some children were referred to the child and adolescent psychiatry department (CAPD) for further evaluation. At the CAPD outpatient clinics, the children who were referred from the ED were examined in detail according to the Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition , for possible diagnosis of ADHD. After evaluation of their sociodemographic characteristics and the ADHD test scores that were recorded, the diagnosis of ADHD in these children was established or ruled out.

Results: It was observed that 41 of the 134 children (30.60%) who presented to the ED with mild head trauma and 12 of the 134 children (8.96%) in the control group were diagnosed with ADHD ( P = 0.0001). When ADHD is corrected for sex, 29 of the 41 cases (70.7%) diagnosed with ADHD were boys and 12 (29.3%) were girls ( P = 0.000). According to the Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition , when the patients who had been diagnosed with ADHD were grouped according to the ages of the children, no statistically significant difference was found between the groups in terms of ADHD ( P = 0.097).

Conclusions: The prevalence of ADHD has been found to be higher in children of primary school age who present to the ED with mild head trauma. Hence, it can be deduced that the diagnosis of childhood ADHD increases the risk of presenting to the ED with head trauma. We believe that it is very important to keep the possible diagnosis of ADHD in mind and to refer that cases to the CAPD in case of high clinical suspicion, especially in primary school boys who are admitted to the ED with mild head trauma. We believe that in this way, morbidity and mortality due to head trauma in this age group can be significantly reduced.
