Thereafter, he noticed gait disturbance and began to tell inconsistent stories. He was admitted to our hospital due to aggravation of these symptoms. On admission, he was(More)
The aim of this study was to investigate physiological mechanisms underlying ataxia in patients with ataxic hemiparesis. Subjects were three patients with ataxic hemiparesis, whose responsible lesion was located at the posterior limb of internal capsule (case 1), thalamus (case 2), or pre- and post-central gyri (case 3). Paired-pulse transcranial magnetic(More)
A 22-year-old man with a previous uveitis episode was admitted to our hospital because of persistent hiccup. On admission, he presented right-upper quadrantanopia, mydriasis and lack of the light reflex in the left eye, left-sided hemiplegia, and bilateral pathologic hyperreflexia. The MR fluid attenuated inversion recovery images showed left side dominant,(More)
Abnormal plasticity has been reported in the brain of patients with Parkinson's disease (PD), especially in the striatum. Although both L-Dopa and dopamine agonist remain to be the mainstay of the treatment in PD, their differential effects on cortical plasticity are unclear. We applied quadripulse stimulation (QPS) over the primary motor cortex (M1) in ten(More)
We have reported two patients with posterior spinal artery syndrome. Both of them had sudden onset back pain, paraparesis, loss of deep sensation and bladder-bowel disturbances. MRI disclosed spinal cord lesions positioned at its posterior part including the posterior column or posterior horn at thoracic levels. Spinal artery syndrome is a rare disorder,(More)
