Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 × 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802(More)
BACKGROUND Neurological involvement in sarcoidosis is serious and often aggressive. Many patients respond to steroids but some show a progressive course despite treatment with steroids and even more potent immunosuppressive drugs. OBJECTIVE The aim of this study was to describe our experience in the treatment of refractory neurosarcoidosis with(More)
PURPOSE To analyze brain metabolite changes in HIV-1-seropositive subjects in order to define whether the neuronal impairment is a localized or more diffuse process. MATERIALS AND METHODS 15 patients and 18 volunteers underwent multivoxel proton magnetic resonance (MR) spectroscopy at 1.5T. Nine patients were classified as being neuropsychiatrically(More)
Three patients with Parkinson's disease are described who developed pericardial, retroperitoneal, and pleural fibrosis associated with pergolide treatment. Surgical intervention was required in all three cases, either to reach a tissue diagnosis or for potentially life threatening complications. Symptoms emerged on average 2 years after the institution of(More)
We describe a 32-year-old woman with sequential, severe, painless visual loss in one eye and then the other, and three temporally distinct episodes of neurological disturbance suggestive of demyelination in the spinal cord. She was positive for the T14484C mutation in the mitochondrial genome, one of three common mutations causing Leber's hereditary optic(More)
Patients with Alzheimer's disease have an impairment of inhibitory control for reasons that are currently unclear. Using an eye-tracking task (the gap-overlap paradigm), we examined whether the uncorrected errors relate to the task of attentional disengagement in preparation for action. Alternatively, the difficulty in correcting for errors may be caused by(More)
Progressive non-fluent aphasia (PNFA) is typically associated with pathological changes consistent with frontotemporal lobar degeneration. A 65-year-old male presented with effortful speech, markedly impaired naming and features of speech apraxia, consistent with PNFA. Perceptuospatial function, calculation and executive function were intact. Brain SPECT(More)
