BACKGROUND Focal dystonia of acute onset is indicative of a structural lesion in the nervous system. Cerebellar lesions have rarely been associated with dystonia. CASE DESCRIPTION A 42-year-old woman was admitted to the neurology ward because of fever, confusion, and gait unsteadiness. She was diagnosed as having tuberculous meningitis, and, after a few days of antituberculous treatment, she ...

Abstract INTRODUCTION Glioblastoma cells broadly infiltrate into surrounding brain parenchyma. In this study, we investigated the influence of tumor invasion on cognitive function in glioblastomas, using diffusion tensor imaging (DTI) . METHODS Participants were 32 patients with right hemispheric glioblastoma who underwent surgery Kanazawa University Hospital (mean age, 61.8 years). We evaluate...

Two patients with residual nonfluent aphasia after ischemic stroke received an intention treatment that was designed to shift intention and language production mechanisms from the frontal lobe of the damaged left hemisphere to the right frontal lobe. Consistent with experimental hypotheses, the first patient showed improvement on the intention treatment but not on a similar attention treatment....

Subthalamic nucleus (STN) is a target of choice for the neurosurgical treatment of Parkinson's disease (PD). The therapeutic effect of STN lesion in PD is classically ascribed to the rescue of physiological activity in the output structures of the basal ganglia, and little is known about the possible involvement of the striatum. In the present study, therefore, we electrophysiologically recorde...

deep brain stimulation (dbs) is a neurosurgical procedure that enables brain structures to be stimulated electrically by a pacemaker implanted under the skin. in the 1980s, over a decade after its first use in pain, implantable dbs of the thalamus was performed to suppress tremor in parkinson’s disease (pd) refractory to drug treatments. primate-based research soon afterwards identified the sub...

Dear Editor, A 35-year-old man presented with severe headache and left sided hemiparesis since one day prior to admission. He reported frequent bouts of oral and genital aphthous ulcers, an attack of deep venous thrombosis of left lower extremity, one episode of right knee arthritis, and several attacks of headache, neck rigidity, and fever. He had been a victim of mustard-gas poisoning at the ...

Basal ganglia disorders are common clinical conditions characterised by specific motor dysfunction and associated behavioral problems. The underlying pathophysiology primarily consists in alterations of the cortico-striato-thalamo-cortical pathways, which can be related to both neurodegenerative pathology (e.g. Parkinson disease, Huntington disease) and neurodevelopmental processes (e.g. Touret...

BACKGROUND AND PURPOSE We investigated the residual abnormalities on computed tomography in a series of patients with proven intracerebral hemorrhage to determine whether the type of lesion is related to the site and size of the initial hematoma. METHODS In a partially prospective follow-up study, we studied computed tomographic scans of 42 patients with spontaneous intracerebral hemorrhage a...

Dopamine (DA) exerts synaptic organization of basal ganglia circuitry through a variety of neuronal populations in the striatum. We performed conditional ablation of striatal neuronal types containing DA D2 receptor (D2R) by using immunotoxin-mediated cell targeting. Mutant mice were generated that express the human interleukin-2 receptor alpha-subunit under the control of the D2R gene. Intrast...
