Abstract
IntroductionAttention deficit/hyperactivity disorder (ADHD) is one of the most common childhood disorders and frequently seen in other conditions like epilepsy as well. The prevalence of ADHD in the general paediatric population is estimated at 3–6% persisting into adulthood in up to one third of persons affected. The prevalence of ADHD in epilepsy is understood to be significantly higher. Approximately one third of children with epilepsy do also have a diagnosis of ADHD. How these attention problems develop over the years is however not clear. We therefore evaluated the severity of attention problems in children with epilepsy at late childhood and assessed it again in adolescence. Data was being compared with attention problems of children with developmental ADHD. Method16 boys with diagnosed combined idiopathic epilepsy/ADHD and 14 boys with developmental ADHD were investigated twice; at a mean age of 10.94 (SD = 1.63) and then again at a mean age of 15.82 (SD = 2.0). At the baseline examination all patients completed Raven's Progressive Matrices to assess intelligence. To measure symptom severity of ADHD, parents were asked to complete the short version of the Conner's Rating Scale for Parents at both times. Parents of children with combined epilepsy/ADHD furthermore gave information about seizure frequency and intake of anticonvulsants. ResultsPatient groups did not significantly differ in age and IQ. Results of the baseline examination revealed elevated scores in both patient groups for the Conner's Rating Scales; ADHD group: M = 16.86 (SD = 5.35); Epilepsy/ADHD group: M = 14.77 (SD = 4.76) but no differences between the groups (p = .29; z = .39). Qualitatively, patients with developmental ADHD showed more abnormalities in the area of hyperactivity/impulsivity while patients with epilepsy/ADHD had more problems with inattention. Results of the follow-up examination showed a significant reduction of symptoms in the ADHD group of minus 4.23 points; M = 12.63 (SD = 3.89) (p = .02); The reduction in the epilepsy/ADHD group was even bigger with minus 6.77 points; M = 8.00 (SD = 6.46) (p = .03). However, difference between the two groups reached no significance (p = .079; z = 1.19). None of the patients with epilepsy has had seizures in the meantime. ConclusionWe found a significant reduction of ADHD symptoms in our patients from the time of late childhood to adolescence. That symptoms of ADHD, especially hyperactivity, lessen with age is known from the literature (Biedermann et al., 2010). We found the same data for patients with idiopathic epilepsy and ADHD. Over the same period of time problems of attention improved substantially. We conclude that development and brain maturation may have a similar positive effect on attention problems in children with epilepsy than in developmental ADHD.
