Psychiatric aspects of progressive supranuclear palsy.
Progressive supranuclear palsy (PSP) is characterized by supranuclear ophthalmoplegia mainly affecting vertical gaze, nuchal dystonia in extension, pseudobulbar palsy, and mental changes. The literature on PSP has been neurologically oriented whereas the psychiatric aspects have been relatively neglected. A review of the literature shows that psychiatric disturbance in PSP is common but with no characteristic pattern. Cognitive impairment, nonspecific affective and behavioral disturbances are commonly found, whereas frank psychosis or bipolar disorder are rare. Misdiagnoses with psychiatric disorders are common and a heightened awareness of the condition is necessary for early diagnosis.
