BACKGROUND Differential diagnosis between idiopathic Parkinson's disease (PD) and multiple system atrophy (MSA) is often difficult in early disease stages. Since MSA is misdiagnosed as PD in more than 20% of the early stages, there is need for methods refining the differentiation of the two disease entities. In PD postganglionic involvement of the autonomic(More)
Epilepsy surgery is based upon the minute assessment of brain tissue generating epileptic activity. A number of diagnostic methods are employed in the process of presurgical evaluation, supplying information on various morphological and functional aspects, ultimately integrated into the general result fundamental to the final treatment decision. Magnetic(More)
Substantial plasticity of the mature mammalian somatosensory cortex was demonstrated after deprivation of sensory input produced by amputation or somatosensory deafferentation. Following transection of the median nerve, adult owl and squirrel monkeys exhibit extensive reorganization in the cortical representation of the hand in areas 3b and 1. In the(More)
Parvovirus B19 DNA was detected by polymerase chain reaction in the brain biopsy specimen from a 67-year-old immunocompetent woman with severe chronic lymphocytic meningoencephalitis. In addition to parvovirus B19, Epstein-Barr virus DNA was identified in the CSF. Genomic material from Epstein-Barr virus was absent in the brain tissue. Clinical symptoms and(More)
Centronuclear myopathy (CNM) is a slowly progressive congenital myopathy with characteristic histopathological findings of chains of centrally located myonuclei in a large number of muscle fibers. Recently, different missense mutations in the dynamin 2 gene (DNM2, 19p13.2) have been shown to cause autosomal dominant CNM. We re-evaluated patients with a(More)
A case of inadvertent intrathecal injection of diatrizoate meglumine is presented. After myelography with 10 ml i.e. 6.5 g Angiografin, a 76-year-old man rapidly developed myoclonus, drowsiness and excessive metabolic acidosis. He died only a few hours later. Postmortem showed non-specific brain edema. RP-HPL-Chromatography confirmed high concentration of(More)
We studied the post-ganglionic cardiac sympathetic innervation in patients with chronic temporal lobe epilepsy (TLE) by means of [(123)I]metaiodobenzylguanidine-single photon computed tomography (MIBG-SPECT) and evaluated the effects of carbamazepine on cardiac sympathetic innervation. TLE is frequently associated with dysfunction of the autonomic nervous(More)
The consumption of the jet set drug Ecstasy (3,4-methylenedioxymetamphetamine, abbreviated to MDMA) by young people is increasing markedly. Parallel to this development, there is a large number of reports on severe neurological, psychiatric and medical complications following the use of Ecstasy. Seizures are among the most common clinical complications of(More)
Cortical reorganization of the subtly differentiated hand map after peripheral nerve injury might be better understood if there was a topographic conception of the homuncular representation of the dorsal finger surfaces in humans, in addition to the well-established sequential rostrocaudal array of the ventral finger aspects in cortical area 3b. In the(More)
We investigated cardiac sympathetic innervation by metaiodobenzylguanidine (MIBG) imaging in a patient with tonic pupils, loss of tendon reflexes, and segmental anhidrosis (Ross syndrome). Despite normal cardiovascular reflex tests, we observed a reduced global myocardial MIBG uptake as well as a regional uptake defect over the posterolateral cardiac(More)
