BACKGROUND For children with attention deficit/hyperactivity disorder (ADHD), a reduction of inattention, impulsivity and hyperactivity by neurofeedback (NF) has been reported in several studies. But so far, unspecific training effects have not been adequately controlled for and/or studies do not provide sufficient statistical power. To overcome these(More)
In a randomized controlled trial, neurofeedback (NF) training was found to be superior to a computerised attention skills training concerning the reduction of ADHD symptomatology (Gevensleben et al., 2009). The aims of this investigation were to assess the impact of different NF protocols (theta/beta training and training of slow cortical potentials, SCPs)(More)
BACKGROUND Learned self-control of slow cortical potentials (SCPs) may lead to behavioral improvement in attention-deficit/hyperactivity disorder (ADHD). Hence, training effects should also be reflected at the neurophysiological level. METHODS Thirteen children with ADHD, aged 7-13 years, performed 25 SCP training sessions within 3 weeks. Before and after(More)
In children with attention-deficit hyperactivity disorder (ADHD), motoric hyperactivity is one of the striking abnormalities. Because this symptom might be due to an insufficient motor control, motor system excitability in 18 drug-naive ADHD-children aged 8-12 years was compared to 18 age-matched healthy children using the technique of transcranial magnetic(More)
OBJECTIVE In a randomized controlled trial, we could demonstrate clinical efficacy of neurofeedback (NF) training for children with ADHD (Gevensleben et al., 2009a). The present investigation aimed at learning more about the neuronal mechanisms of NF training. METHODS Children with ADHD either completed a NF training or a computerized attention skills(More)
This experimental animal study was performed in order to assess possible long-term effects of the administration of the selective serotonin reuptake inhibitor fluoxetine (Prozac) during early periods of juvenile life on the developing central serotonergic and noradrenergic systems. Fluoxetine was administered via the drinking water (5 mg/kg/day) for a(More)
For children with attention-deficit-hyperactivity disorder (ADHD) or tic disorder (TD), we recently reported deficient inhibitory mechanisms within the motor system by using transcranial magnetic stimulation. These deficits--stated as reduced intracortical inhibition in ADHD and shortened cortical silent period in TD--could be seen as neurophysiological(More)
Methylphenidate is widely and effectively used for the treatment of attention deficit hyperactivity disorder during early childhood and adolescence, but until now possible effects of this treatment on brain development and the maturation of monoaminergic systems have not been investigated systematically. This experimental animal study describes the effects(More)
The binding parameters of highly selective ligands of serotonin (5-HT) transporters ([3H]paroxetine), noradrenaline (NE) transporters ([3H]nisoxetine), and of dopamine (DA) transporters ([3H]GBR-12935) were determined on membrane preparations from frontal cortex, striatum, midbrain and brain stem of Wistar rats on postnatal days 25, 50, 90 and 240, i.e.,(More)
Decreased motor inhibition was reported in adult patients with tic disorder (TD) using the technique of transcranial magnetic stimulation. Since tics usually begin during childhood, motor threshold, cortical silent period (CSP) and intracortical inhibition/facilitation were measured in 21 TD children and 25 healthy children aged 10-16 years. In TD children(More)
