A clinical diagnosis of normal-pressure hydrocephalus was entertained. Imaging did not support this, however, and on formal testing, abnormal nystagmus and eye movements were detected. This appearance has been called the "hummingbird sign" or "penguin sign". Also, atrophy of the tectum is seen, particularly the superior colliculi.
These findings suggest the diagnosis of progressive supranuclear palsy. Frontal PSP initially presents with behavioural and cognitive symptoms, with or without ophthalmoparesis and then evolve into typical PSP. However, several distinguishing features exist. Case reports of rehabilitation programs for patients with PSP generally include limb-coordination activities, tilt-board balancing, gait training , strength training with progressive resistive exercises, and isokinetic exercises and stretching of the neck muscles.
Individuals with PSP are often referred to occupational therapists to help manage their condition and to help enhance their independence. This may include being taught to use mobility aids. The poor prognosis is predominantly attributed to the serious impact this condition has on the quality of life. Pneumonia is a frequent cause of death. Charcot described a year-old woman who had rigid-akinetic parkinsonism, neck dystonia, dysarthria, and eye-movement problems. Chavany and others reported the clinical and pathologic features of a year-old man with a rigid and akinetic form of parkinsonism with postural instability, neck dystonia, dysarthria, and staring gaze in Progressive supranuclear palsy was first described as a distinct disorder by neurologists John Steele, John Richardson, and Jerzy Olszewski in
