Methylphenidate is commonly believed to lower seizure threshold. The safe use of methylphenidate has not been clarified in patients with attention-deficit hyperactivity disorder (ADHD) and concomitant active seizure or electroencephalographic (EEG) abnormalities. Patients with ADHD and active seizures (n = 57) and patients with ADHD and EEG abnormalities (n = 62), 6 to 16 years of age, were included in the study. The safety and efficacy of treatment with antiepilepsy drugs combined with methylphenidate were determined by assessing seizure frequency, changes in ADHD symptoms, the Conners' Rating Scales, EEG differences, and side effects. The Conners' Rating Scales, performed by parents and teachers, and mean total ADHD symptom scores at the beginning of the study and at the end were significantly different (P = .05 for the Conners' Rating Scales and P = .001 for ADHD symptom scores). Methylphenidate had a beneficial effect on EEG. Seizure frequency did not change from baseline. The side effects of methylphenidate were mild and transient Methylphenidate is safe and effective in children with ADHD and concomitant active seizures or EEG abnormalities.

The most important risk factors for epilepsy in this study were neurological impairment, history of atypical febrile seizures, severe head injury and a low apgar score. Other important risk factors were moderate head trauma and a history of epilepsy in the family.

As negative effects of the disease increased, the QoL of IMD patients and their parents decreased in terms of emotional, physical, and cognitive function. Application of expanded newborn scanning programs, early diagnosis, regular follow up, and family education would lessen the effects of the disease and improve the QoL of both families and children.

Low-risk preterm children achieve lower scores in neurophysiological tests than children born at term. Preterm birth itself has a significant impact on regional brain volumes and cognitive outcome of children at 9 years of age. It is a risk factor for regional brain volume reductions in preterm children with low risk for neurodevelopmental deficits. The significant interaction between cerebellar volume reduction and executive function and attention may suggest that even in preterm children at low risk can have different trajectories in the growth and development of overall brain structure.
