Progressive Supranuclear Palsy (PSP)
Diagnosis of PSP
Clinical evaluation Diagnosis of progressive supranuclear palsy is clinical. MRI is usually done to exclude other disorders. In advanced cases, MRI shows a characteristic decrease in midbrain size that is best seen on midsagittal views and that causes the midbrain to be shaped like a hummingbird or emperor penguin. On axial views, the midbrain may resemble a morning glory ( Diagnosis references ). 1.Höglinger GU, Respondek G, Stamelou M, et al: Clinical diagnosis of progressive supranuclear palsy: The Movement Disorder Society criteria.
