At this time, there are no widely accepted criteria for the diagnosis of multifocal motor neuropathy. Furthermore, there is insufficient empirical data to define clinical and laboratory features that may reliably separate certain lower motor neuron syndromes with overlapping features as distinct. The AAEM therefore developed five criteria through a formal(More)
Preliminary data suggest potential benefit of 5-HT receptor agonists in the treatment of ataxias. We studied the effects of buspirone in a cohort of twenty patients with spinocerebellar ataxia (SCA). Twenty patients were treated in this double-blind, placebo controlled, cross-over trial with either buspirone HCl 30 mg twice daily or placebo for 3 months.(More)
Patients with myasthenia gravis might develop various cardiac disorders, yet a causal relationship remains unestablished. Because causes of sudden death in this population have not been ascertained, further attention to possible cardiac disease in this population is warranted. We summarize the current literature and describe the possible etiologies and(More)
The Ataxia Functional Composite Scale (AFCS) may provide a sensitive and reproducible assessment of treatment responses in studies of the spinocerebellar ataxias (SCA). We previously assessed the effects of buspirone in a cohort of patients with SCA via the International Cooperative Ataxia Rating Scale (ICARS). At each assessment period, AFCS scores were(More)
Many studies have shown an inverse relationship between axon length (or height) and nerve conduction velocity. A linear relationship was assumed, but there is no physiologic indication the relationship is linear. Furthermore, a linear relationship between height and velocity leads to implausibly low velocities for very long nerves. We propose that power(More)
We describe a patient with acute progressive weakness and areflexia. Both botulism and Miller-Fisher variant of Guillain-Barré syndrome were initial diagnostic considerations, and she was treated with intravenous immunoglobulin and botulinum antitoxin. A mouse bioassay was positive for botulinum toxin A, although her clinical course, electrodiagnostic(More)
PURPOSE To determine whether Contraction Induced H Reflexes (CIHR) can accurately detect cervical radiculopathy. METHODS Comparison of CIHR results with Needle Electromyography at academic outpatient Electromyography/Nerve Conduction laboratories. Participants were all patients over 18 with a needle electromyography diagnosis of cervical radiculopathy.(More)
Hereditary motor and sensory neuropathy with proximal predominance (HMSN-P) is a rare disorder inherited in an autosomal dominant fashion. Patients present with slowly progressive proximal-predominant weakness, painful muscle cramps, fasciculations, large-fiber sensory loss, and areflexia. Electrodiagnostic (EDX) studies typically reveal abnormalities(More)
