Patients with cerebellar infarction frequently make an excellent functional recovery. However, the mechanisms of functional recovery from cerebellar infarction remain unclear. Thus, functional MRI was used to investigate these mechanisms in six right-handed patients with complete recovery after cerebellar infarction, and nine right-handed normal subjects.(More)
The motor mechanisms of a patient with unilateral hand clumsiness in the early stages of akinetic-rigid syndrome were assessed by functional magnetic resonance imaging (fMRI). Movements of the unaffected hand produced activation in the contralateral sensorimotor cortex (SMC) and ipsilateral SMC and superior parietal lobule (SPL). The affected hand activated(More)
We report a 55-year-old man with a chief complaint of wasting and weakness of the left quadriceps muscle. At age 54, he noticed difficulty in running and weakness in the left thigh, which gradually progressed. On the first admission to our hospital, based on the nerve conduction studies (NCS), the muscle biopsy findings showing neurologenic changes, and no(More)
A 54-year-old female developed dysarthria, left limb ataxia, and crossed dissociated sensory impairment, followed by external ophthalmoplegia, severe bulbar palsy and bilateral pyramidal tract involvement. A high titer of anti-GQ1b IgG antibody was detected in her serum. Brain MRI (T2 weighted image, diffusion weighted image) and peripheral nerve conduction(More)
