OBJECTIVE Myoclonus is characterized by sudden, brief involuntary movements, and its presence is debilitating. We identified a family suffering from adult onset, cortical myoclonus without associated seizures. We performed clinical, electrophysiological, and genetic studies to define this phenotype. METHODS A large, 4-generation family with a history of(More)
A patient with herpes zoster ophthalmicus developed hemiparesis that at first responded to steroids but, when these were reduced, culminated in massive cerebral infarction and death. The cause was an extensive necrotizing arteritis of large and small cerebral arteries. Herpes-like virions were identified in smooth muscle cells of the middle cerebral artery.
Familial Danish dementia (FDD) is a rare neurodegenerative disorder, which is pathologically characterized by widespread cerebral amyloid angiopathy, parenchymal protein deposits and neurofibrillary degeneration. FDD is associated with mutation in the BRI gene. In FDD a decamer duplication between codons 265 and 266 in the 3' region of the BRI gene(More)
The ability of galantamine (Reminyl) to inhibit the aggregation and toxicity of the beta-amyloid peptide (Abeta) was investigated. Galantamine showed concentration-dependent inhibition of aggregation of both Abeta 1-40 and Abeta 1-42, as determined by an ELISA method. Electron microscope studies of Abeta 1-40 incubated in the presence of galantamine(More)
Whether pure thiamine deficiency produces a neuropathy in Mammalia is still debated. Rats were pair-fed-synthetic diets with and without thiamine. When studied histochemically, soleus muscles from thiamine-deficient rats showed (1) small, angular fibers that had high NADH dehydrogenase activities; (2) a loss of 43% of type II (FOG) fibers; (3) decreased(More)
