Progressive supranuclear palsy: pneumoencephalography, electronystagmography and treatment with methysergide
Abstract:
15 patients with progressive supranuclear palsy (PSP) are presented with discussion of the value of pneumoencephalography (PEG) and electronystagmography (ENG) in confirming the diagnosis. PEG was performed in 6 patients, and revealed atrophy in the area of the pons and colliculi. ENG, which also was performed in 6 patients, 4 of whom had PEG, confirmed the defects in extraocular movement. Methysergide, which has been suggested as therapy for PSP, was utilized in 6 patients with no evidence of significant improvement.
