Progressive supranuclear palsy is sufficiently rare and difficult to diagnose that it escaped clinical recognition until 1964, when Steele, Richardson, and Olszewski clarified it as a pathologic entity. From January 1981 to June 1989, 7 patients who fulfilled the Golbe's criteria of progressive supranuclear palsy were admitted to the neurological department of National Taiwan University Hospital. The mean age at onset was 60 years (range: 53-69 years), and the mean age at diagnosis was 63 years), and the mean age at diagnosis was 63 years (range: 55-71 years). The study failed to identify any specific risk factors associated with progressive supranuclear palsy. Unsteady gait, vertical gaze palsy, pseudobulbar palsy, parkinsonian features and dementia were noted in all cases. The brain computed tomography revealed mild cortical atrophy and ventricular dilatation in 5 patients. Additionally, electroencephalography revealed diffuse theta waves in 4 patients and temporal theta waves in 2 patients, but these findings were nonspecific. Nystagmograms were performed in 3 patients, and hypometric saccades were noted in all of these patients, and uninhibited neurogenic bladder was proven by cystometry in 2 of these patients. All patients were treated with levodopa, but none of the patients showed any beneficial effects. Two patients died of aspiration pneumonia; the average duration from onset to death was about 4 years.

A 64-year-old male patient of amyotrophic lateral sclerosis (ALS) with frozen gait, axial rigidity and supranuclear upper gaze palsy was reported. We have followed this patient more than four years. He was well until November 1982, when he noticed weakness of left arm. In March 1983, he noticed hypogeusia and in July, he developed dysarthria and frozen gait. On admission, he was alert and oriented. Neurological examination revealed dysarthria, dysphagia and muscular weakness and atrophy in bilateral upper extremities, dominantly in left side. He showed remarkable frozen gait, retropulsion and could not walk. Brain CT showed mild dilatation of the third ventricle. In August 1988, he showed tongue atrophy, and weakness and atrophy of the extremities progressed during these four years. He also showed axial rigidity and frozen gait. Brain CT showed severe third ventricular dilatation and atrophy of tegmentum of the midbrain and cerebellum that were compatible with progressive supranuclear palsy (PSP). Six months later, he developed upper gaze palsy. From these findings, we concluded that this patient had a quite unique clinical features of both ALS and PSP.

The cerebrospinal fluid (CSF) absorption mechanism in cases of hydrocephalus was investigated on the basis of measurements of CSF flow in a shunt tube after ventriculo-peritoneal shunt surgery, monitoring of intracranial pressure, CT findings, radioisotope cisternography, cerebral blood flow, EEG, PSP tests and changes in neurological findings. The subjects were 6 males and 7 females aged from 18 to 70. CSF flow rates in the shunt tubes were between 0.01 and 1.93 ml/min. Calculating the daily volume of CSF flow, the subjects were divided into two groups: Group A (8 patients) with a volume of less than 150 ml/day (0.01-0.25 ml/min), and Group B (5 patients) with between 150 and 500 ml/day (0.01-1.93 ml/min). Monitoring of intracranial pressure prior to the shunt operation was performed in 10 cases. These pressure values ranged between 4 and 25 mmHg (mean: 7-8 mmHg), and there was no difference between the two groups. The pre-and post-operative radioisotope cisternography findings indicated improvement of ventricular dilatation, periventricular lucency and ventricular reflux. After the shunt operations, there was neurological improvement in 6 of the 8 Group A cases but only in 2 of the 5 Group B cases. Considering the CSF flow volumes of the two groups, it appears that in Group A the shunt tube is not the main CSF circulation pathway. This could mean that resistance to CSF absorption in the cerebrospinal space has decreased after the shunt operation and there has been recovery of the physiological CSF absorption pathways. In other words, neurological improvement can be expected in this group A.

Regional brain volumes were measured in 21 patients with progressive supranuclear palsy (PSP), 17 patients with Parkinson's disease and 23 controls using 3D MRI-based volumetry. Cortical, subcortical and ventricular volume measures were correlated with global indices of motor disability and cognitive disturbance. All MRI measures, including hippocampal volume, were preserved in Parkinson's disease. Patients with PSP could be distinguished from both Parkinson's disease and controls by whole brain volume loss, ventricular dilatation and disproportionate atrophy of the frontal cortex. Caudate nucleus volume loss additionally differentiated PSP from controls, but was modest in severity and proportionate to whole brain volume loss. The present study identifies disease-specific differences in the topography of brain atrophy between PSP and Parkinson's disease, and has potential implications for the in vivo radiological differentiation of these two disorders. In PSP, the variance in frontal grey matter volume related to measures of behavioural disturbance, confirming the use of behavioural tests for ante-mortem case differentiation and suggesting that intrinsic cortical deficits contribute to these clinical disturbances.
