The "hummingbird" lady: A case report on progressive supranuclear palsy

Abstract

Progressive supranuclear palsy (PSP) is a rare neurodegenerative disease, which tends to be progressive, causing weakness of the structures in the brain stem that controls eye movements. PSP falls under the rubric of Parkinsonism plus syndromes that are a group of heterogeneous degenerative neurological disorders that differ from the classical idiopathic Parkinson′s disease. PSP is often underreported, making it important for clinicians to be aware of this disorder. Here we report a case of PSP, which presented primarily with speech disturbances and recurrent falls due to postural instability. On investigating, the magnetic resonance imaging (MRI) revealed a classical sign diagnostic of PSP.
