title: Progressive supranuclear palsy: report of two cases (author's transl).
abstract: Two cases of progressive supranuclear palsy (PSP) are reported in two men (49 and 75years old) who for one and four years respectively had sudden falling while walking. Rigidity of the neck was an carly feature that prgressed to involve the upper trunk while "subcortical dementia", dysarthria and dysphagia appeared. They had a complete paralysis of vertical eye movements and slow horizontal voluntary eye movements. Oculocephalic reflexes were intact. On caloric stimulation vestibulo-ocular responses were present but only slow saccadic eye movements were observed. With surface electrodes eye movements were studied during the REM phase of sleep. Our patients had both vertical and horizontal eye movements during paradoxal sleep. This findings is in keeping with a supranuclear ophtalmoplegia, and may help in antemorten diagnosis of PSP.
