Motor threshold is a means of quantifying stimulus in transcranial magnetic stimulation. Two methods are used. One involves neurophysiology techniques and the other is visualization of movement. The aim was to compare the percentage of total machine output (PTMO) necessary to achieve motor threshold using these different methods. Neurophysiological and(More)
OBJECTIVE Spinal muscular atrophies (SMAs) are hereditary disorders characterized by weakness from degeneration of spinal motor neurons. Although most SMA cases with proximal weakness are recessively inherited, rare families with dominant inheritance have been reported. We aimed to clinically, pathologically, and genetically characterize a large North(More)
We report the case of a 13-year-old boy with poorly controlled type 2 diabetes mellitus who developed severe diabetic amyotrophy, which progressed over a few months but demonstrated rapid recovery after administration of intravenous immunoglobulin. This report highlights the importance of monitoring adolescents for even the rare neurologic complications of(More)
Hypertension-induced encephalopathy is a recognized pathological process commonly focused in the parietal and occipital lobes of the cerebral hemispheres. The parenchyma of the posterior fossa is infrequently involved. The authors report on two cases of isolated edema of the cerebellar hemispheres, which occurred in the setting of hypertensive crisis and(More)
BACKGROUND The relationship between the autonomic reflex screening test (ARS) and measures of sensory function and structure (quantitative sensory testing (QST) and intraepidermal nerve fiber density (IENFD)) remains uncertain in patients with distal small fiber neuropathy (SFN). The aim of this study was to evaluate the correlations among a range of(More)
Importance There is growing interest in the role of nutrition in the pathogenesis and progression of amyotrophic lateral sclerosis (ALS). Objective To evaluate the associations between nutrients, individually and in groups, and ALS function and respiratory function at diagnosis. Design, Setting, and Participants A cross-sectional baseline analysis of(More)
OBJECTIVES To characterize the prevalence of cognitive and behavioral symptoms using a cognitive/behavioral screening battery in a large prospective multicenter study of amyotrophic lateral sclerosis (ALS). METHODS Two hundred seventy-four patients with ALS completed 2 validated cognitive screening tests and 2 validated behavioral interviews with(More)
Abstract In a multicenter study of newly diagnosed ALS patients without a reported family history of ALS, we are prospectively investigating whether markers of oxidative stress (OS) are associated with disease progression. Methods utilize an extensive structured telephone interview ascertaining environmental, lifestyle, dietary and psychological risk(More)
INTRODUCTION We evaluated incorporation of the quantitative sudomotor axon reflex test (QSART) into the diagnostic criteria for small fiber neuropathy (SFN) as an addition to quantitative sensory testing (QST) and intraepidermal nerve fiber density (IENFD) testing. METHODS One hundred one patients with clinically suspected SFN underwent QSART, QST, and(More)
Multiple sclerosis (MS) is a multifactorial disease in which genetic and environmental factors apparently have a major influence on the susceptibility and course of the disease. In the present study we have investigated the genetic basis and subclass levels of IgG in MS. Hundred and thirty-six Norwegian patients with MS and 92 controls were genotyped for(More)
