Recovery of function after a stroke is determined by a balance of activity in the neural network involving both the affected and the unaffected brain hemispheres. Increased activity in the affected hemisphere can promote recovery, while excessive activity in the unaffected hemisphere may represent a maladaptive strategy. We therefore investigated whether(More)
OBJECTIVE To study the efficacy of 15 Hz repetitive transcranial magnetic stimulation (rTMS) in treating depression in patients with Parkinson's disease. METHODS 42 patients were enrolled into two groups: group 1, active rTMS (15 Hz rTMS for 10 days) and placebo drug treatment; group 2, sham rTMS and fluoxetine 20 mg/day. A specially designed sham coil(More)
Previous studies show that cognitive functions are more impaired in patients with Parkinson's disease (PD) and depression than in nondepressed PD patients. We compared the cognitive effects of two types of antidepressant treatments in PD patients: fluoxetine (20 mg/day) versus repetitive transcranial magnetic stimulation (rTMS, 15 Hz, 110% above motor(More)
OBJECTIVE To study the therapeutic effects on auditory hallucinations refractory to clozapine with 1-Hz repetitive transcranial magnetic stimulation (rTMS) applied on the left temporoparietal cortex. METHOD Eleven patients with schizophrenia (DSM-IV) experiencing auditory hallucinations (unresponsive to clozapine) were randomly assigned to receive either(More)
BACKGROUND Transcranial magnetic stimulation (TMS) is a noninvasive method to stimulate the cortex, and the treatment of depression is one of its potential therapeutic applications. Three recent meta analyses strongly suggest its benefits in the treatment of depression. The present study investigates whether repetitive TMS (rTMS) accelerates the onset of(More)
OBJECTIVE To study the effects of repetitive transcranial magnetic stimulation (rTMS) on epileptic EEG discharges in patients with refractory epilepsy and malformations of cortical development (MCDs). METHODS Eight patients with MCD and refractory epilepsy underwent 1 session of low-frequency rTMS (0.5 Hz, 600 pulses) focally targeting the MCD. The number(More)
Repetitive transcranial magnetic stimulation (rTMS) can induce significant antidepressant effects and, for some patients, might be an alternative to electroconvulsive therapy (ECT). The results of studies comparing the efficacy of rTMS and ECT are mixed and, therefore, comparison of these two therapies needs to be further explored. Forty-two patients aged(More)
BACKGROUND Although depression is highly prevalent in Parkinson disease (PD), little is known about the neural correlates associated with depression and antidepressant treatment in PD. OBJECTIVE To examine the effects of fluoxetine and repetitive transcranial magnetic stimulation (rTMS) on regional cerebral blood flow (rCBF) using SPECT in patients with(More)
Many patients with obsessive-compulsive disorder (OCD) do not achieve satisfactory symptom improvement with conventional treatments. Here, we evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) applied over the right dorsolateral prefrontal cortex (rDLPFC) in patients with treatment-resistant OCD. This was a double-blind randomized(More)
Schizophrenia is a complex and heterogeneous psychiatric disorder. Auditory verbal hallucinations occur in 50-70% of patients with schizophrenia and are associated with significant distress, decreased quality of life and impaired social functioning. This study aimed to investigate the effects of active compared with sham 1-Hz repetitive transcranial(More)
