Filter by:Attention Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterized by persistent symptoms of attention deficit and/or hyperactivity/impulsivity . Currently, the first line drugs for treating ADHD are central stimulants such as Tomoxetine and Guanfaxine. However, there is a risk of drug abuse and misuse, which often affects sleep and appetite, only 50% of patients can fully tolerate. This project uses the iTBS stimulation on weekends, children with ADHD finish scale evaluation, magnetic resonance imaging analysis, and cognitive function before and after stimulation, This study explores its therapeutic effect on attention deficit in children and adolescents with ADHD.
It has been shown that prolonged continuous theta burst stimulation (pcTBS) , a relatively new repetitive transcranial magnetic simulation (rTMS) protocol, of the primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) decreases pain in healthy volunteers, in various experimental models. In addition, rTMS of M1 has also been shown to have analgesic effects in various chronic pain conditions, including neuropathic pain.The mechanisms underlying rTMS-induced analgesia remain unclear. Functional neuroimaging studies have shown that rTMS of M1 and DLPFC induces changes in the activity of cortical and subcortical structures involved in pain processing and modulation. Endogenous opioids and e N-methyl-D-aspartate (NMDA) receptor are known to play a major role in these processes. The investigator hypothesized that the endogenous opioids systems (EOS) and NMDA receptor might be involved in the analgesic action of pcTBS. In the first part,the investigator compares the analgesic effects of motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) stimulation before and after naloxone or placebo treatment, the intensity of pain induced by capsaicin were used to evaluate the analgesic effects of pcTBS. If naloxone does not reverse the analgesic effect of pcTBS,The volunteers will be invited to participant the second part of the study, which the investigator compares the analgesic effects of motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) stimulation before and after Ketamine treatment.
This study is based on the characteristics of motor learning theory and motor learning neural network to improve motor function in stroke patients. This study is to investigate whether the cerebral-cerebellar repetitive transcranial magnetic stimulation (rTMS) is effective in improving motor function compared to the conventional cerebral rTMS in stroke patients.
Mental illness rarely occurs as a single, easily categorized condition. Instead, multiple disorders often co-occur. This complicates the treatment plan for many Veterans, especially those suffering the most severe dysfunction. This also means that clinical research aimed at one specific disorder may not be optimized to treat the realworld presentation of neuropsychiatric illness. The investigators propose in this study to develop a novel, non-invasive brain stimulation treatment that would promote rehabilitation for Veterans suffering a wide range of emotional difficulties. More specifically, the investigators propose to up-regulate the brain circuitry that supports flexible problem solving and contending with daily demands. Rather than focusing on reducing the symptoms of a specific disorder to reduce the intrusion into daily life, the investigators propose to augment those brain circuits that promote adaptive cognition and thus quality of life.
