OBJECTIVE The primary aim of this study was to investigate the acute impact of methylphenidate (MPH) on sleep parameters in attention-deficit/hyperactivity disorder (ADHD) children. The second aim was to investigate the different effects of intermediate- and longacting MPH on sleep parameters. The third aim was to test the different effects of dose and age(More)
OBJECTIVE This study was conducted to evaluate the effectiveness of aripiprazole to reduce the severity and frequency of tic symptoms and to evaluate the additional effects of aripiprazole on weight changes in children and adolescents with Tourette disorder (TD) or chronic tic disorders. METHODS A 12-week, open-label trial with flexible dosing strategy of(More)
This study examined the acute effects of ethanol (EtOH) on the firing patterns of Purkinje cells (PCs) using an intracellular recording in slice preparation of rat cerebellum. The experiments were performed in sagittal cerebellar slices (400 micrometer) of adult Sprague-Dawley rats (80-100g). Ethanol was applied by a bath superfusion with a known(More)
Intracellular recordings in cerebellar slice preparation showed that applications of 4-AP altered the pattern of oscillatory firing activity in Purkinje cells (PCs), especially yielding pronounced changes in action potential shape. 4-AP increased the amplitude and duration of action potential significantly and decreased the spike frequency. After 4-AP(More)
Variations in intracellular calcium activity ([Ca2+]i) play crucial roles in information processing in Purkinje neurons such as synaptic plasticity. Although Na+-Ca2+ exchanger (NCX) has been shown to participate in the regulation of homeostasis and secretion in neuronal cells, the physiological role of NCX in Purkinje neurons, such as a role in cerebellar(More)
OBJECTIVE We investigated executive functions (EFs), as evaluated by the Wisconsin Card Sorting Test (WCST), and other EF between lower grades (LG) and higher grades (HG) in elementary-school-age attention deficit hyperactivity disorder (ADHD) children. METHODS We classified a sample of 112 ADHD children into 4 groups (composed of 28 each) based on age(More)
