Progressive supranuclear palsy of PSP is the name Dr. J. Clifford Richardson chose to designate a unusual clinical syndrome he first identified in the 1963.
During the past 30 years, neurologists confirm that progressive supranuclear palsy is a universal, sporadic and not uncommon neurodegeneration of middle and late life.
Progressive supranuclear palsy or Steele-Richardson-Olszewski disease is defined as a typical parkinsonian syndrome characterized by supranuclear gaze impairment, prominent and early postural instability with fails, axial greater than appendicular rigidity and poor or absent response to levodopa.
It is also characterized clinically by neck dystopia, Parkinson, pseudobulbar palsy, and frontal lone-type dementia.
The condition is progressive and leads to death on average about 6 years from onset.
On gross examination the brain usually shows only minor abnormalities or may appear normal. On slicing, the ventricles may be slightly enlarged.
The midbrain is shrunken, particularly the superior colliculi, the mesencephalic tegmentum, and the periaqueductal grey matter.
