OBJECTIVE To assess the effects of focal motor cortex stimulation on motor performance and cortical excitability in patients with Parkinson's disease (PD). METHODS Repetitive transcranial magnetic stimulation (rTMS) was performed on the left motor cortical area corresponding to the right hand in 12 'off-drug' patients with PD. The effects of subthreshold(More)
Thirty-two patients with refractory central and neuropathic pain of peripheral origin were treated by chronic stimulation of the motor cortex between May 1993 and January 1997. The mean follow-up was 27.3 months. The first 24 patients were operated according to the technique described by Tsubokawa. The last 13 cases (eight new patients and five(More)
OBJECTIVE Drug resistant neurogenic pain can be relieved by repetitive transcranial magnetic stimulation (rTMS) of the motor cortex. This study was designed to assess the influence of pain origin, pain site, and sensory loss on rTMS efficacy. PATIENTS AND METHODS Sixty right handed patients were included, suffering from intractable pain secondary to one(More)
BACKGROUND Parkinson's disease is typically treated with oral dopamine replacement therapies; however, long-term treatment leads to motor complications and, occasionally, impulse control disorders caused by intermittent stimulation of dopamine receptors and off-target effects, respectively. We aimed to assess the safety, tolerability, and efficacy of(More)
Five patients with Parkinson's disease, unilaterally transplanted with foetal mesencephalic cells into putamen (n=1) or putamen and caudate (n=4), were followed throughout a period of 15-36 months after surgery, according to the recommendations of the core assessment programme for intracerebral transplantations (CAPIT). All these patients exhibited an(More)
BACKGROUND Huntington's disease is a neurodegenerative disease of genetic origin that mainly affects the striatum. It has severe motor and cognitive consequences and, up to now, no treatment. Motor and cognitive functions can be restored in experimental animal models by means of intrastriatal transplantation of fetal striatal neuroblasts. We explored(More)
The authors present a patient who had long-term improvement of a severe upper limb action tremor after chronic cortical stimulation. A 40-year-old woman complained of facial pain and tremor of the left arm after removal of an acoustic neurinoma. A motor cortex stimulation was performed to treat the deafferentation facial pain in 1993. Chronic cortical(More)
Huntington's disease is a hereditary disease in which degeneration of neurons in the striatum leads to motor and cognitive deficits. Foetal striatal allografts reverse these deficits in phenotypic models of Huntington's disease developed in primates. A recent open-label pilot study has shown some clinical improvement or stabilization in three out of five(More)
Huntington's disease (HD) is an autosomal dominant genetic disease with devastating clinical effects on cognitive, psychological, and motor functions. These clinical symptoms primarily relate to the progressive loss of medium-spiny GABA-ergic neurons of the striatum. There is no known treatment to date. Several neurotrophic factors have, however,(More)
A higher than expected frequency of suicide has been reported among patients undergoing subthalamic nucleus deep brain stimulation (STN DBS) for advanced Parkinson's disease (PD). We conducted a retrospective survey of 200 patients with PD who underwent STN DBS. Two patients (1%) committed suicide and four (2%) attempted suicide, despite clear motor(More)
