OBJECTIVE Associations between peripheral neuropathy and restless legs syndrome (RLS) have been described, but have not been consistently reproduced. If RLS prevalence is truly increased by neuropathy, this has important implications for RLS pathophysiology. METHODS In a case-control design, 245 patients with peripheral neuropathy and 245 age- and(More)
Eighteen patients with definite, untreated chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) of chronic progressive (nine patients) or relapsing course (nine patients) were randomized prospectively to receive 10 plasma-exchange (PE) or sham plasma-exchange (SPE) treatments over 4 weeks in a double-blind trial. After a wash-out period of 5(More)
Susac syndrome (SuS) is a rare disorder thought to be caused by autoimmune-mediated occlusions of microvessels in the brain, retina and inner ear leading to central nervous system (CNS) dysfunction, visual disturbances due to branch retinal artery occlusions (BRAO), and hearing deficits. Recently, a role for anti-endothelial cell antibodies (AECA) in SuS(More)
A 15-year experience with paraneoplastic sensory neuronopathy at the Mayo Clinic is reviewed. Of 26 patients with paraneoplastic sensory neuropathy, 19 had small cell lung cancer, 4 had breast cancer, and 3 had other neoplasms. There was a striking predominance of females (20:6). Neuropathic symptoms (pain, paresthesia, sensory loss) were asymmetric at(More)
The authors report the case of a 39-year-old sighted woman who displayed non-24-hour sleep-wake cycles following a car accident. The phase relationship between endogenous circadian markers such as plasma melatonin and 6-sulfatoxymelatonin rhythms and self-selected sleep times was abnormal. A laboratory investigation indicated that she was sensitive to(More)
An unusual clinical manifestation of nerve hypertrophy in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is described. A patient with a 13-year history of CIDP developed diplopia and proptosis. Imaging of the neuraxis showed marked bilateral trigeminal nerve hypertrophy and lumbosacral nerve root hypertrophy. Biopsy of the right(More)
Because of an incidental observation that the blink reflex was normal in paraneoplastic sensory neuronopathy (SN) and frequently abnormal in nonparaneoplastic SN, the authors reviewed the electromyographic records of patients with SN in whom blink reflex studies were performed. The blink reflex was normal in all 17 patients with paraneoplastic SN and(More)
