OBJECTIVE We hypothesized an increase in dorsolateral prefrontal cortex (DLPFC) glutamate levels would occur after 3 weeks of repetitive transcranial magnetic stimulation (rTMS) treatment and a decrease in major depressive disorder (MDD) symptoms. METHODS We report 6 patients (4 females) 15 to 21 years of age with treatment-resistant MDD. Participants had(More)
AIM Brain plasticity mechanisms are probably different in children but remain poorly understood. Paired afferent stimulation (PAS) combines peripheral sensory stimulation with transcranial magnetic stimulation (TMS) of primary motor cortex to induce rapid, reversible, topographically specific increases in primary motor cortex excitability suggestive of(More)
Expressive dysphasia accompanies left inferior frontal gyrus (IFG/Broca) injury. Recovery may relate to interhemispheric balance with homologous, contralesional IFG but is unexplored in children. We evaluated effects of inhibitory rTMS to contralesional IFG combined with intensive speech therapy (SLT). A 15year-old, right-handed male incurred a left middle(More)
BACKGROUND Perinatal stroke causes most hemiparetic cerebral palsy. Ipsilateral connections from nonlesioned hemisphere to affected hand are common. The nonlesioned primary motor cortex (M1) determines function and is a potential therapeutic target but its neurophysiology is poorly understood. OBJECTIVE We aimed to characterize the neurophysiological(More)
INTRODUCTION Mild traumatic brain injury (mTBI) outcomes are variable, and 10-15% may suffer from prolonged symptoms beyond 3 months that impair the child's return to normal activities. Neurophysiological mechanisms of mTBI are incompletely understood, particularly in children, but alterations in cortical excitability have been proposed to underlie(More)
Smoking cessation aids are limited in number and effectiveness. Combining medicines with diverse mechanisms of action may improve outcome. Baclofen has been suggested as a potentially useful aid to smoking cessation. The authors present their findings from a prospective open-label pilot study of combination therapy with baclofen and bupropion SR. In our(More)
OBJECTIVE To determine whether the addition of repetitive transcranial magnetic stimulation (rTMS) and/or constraint-induced movement therapy (CIMT) to intensive therapy increases motor function in children with perinatal stroke and hemiparesis. METHODS A factorial-design, blinded, randomized controlled trial (clinicaltrials.gov/NCT01189058) assessed rTMS(More)
OBJECTIVE Brain stimulation and constraint therapy may enhance function after perinatal stroke but mechanisms are unknown. We characterized interhemispheric interactions (IHI) in hemiparetic children and explored their relationship to motor function and neuromodulation. METHODS Forty-five hemiparetic perinatal stroke subjects aged 6-19 years completed a(More)
Split-night polysomnography is performed at our centre in all patients with ALS who require assessment for nocturnal hypoventilation and their response to non-invasive ventilation. The purpose of this study was to determine how successful this practice has been, reflected by whether a complete assessment was achieved by a single split-night polysomnogram.(More)
