Progressive supranuclear palsy (PSP) was first recognized as a distinct syndrome by Richardson, Steele and Olszewski roughly a quarter century ago. Subsequent clinical experience has corroborated and enlarged their original observations. PSP has become familiar as a chronic progressive disorder with extrapyramidal rigity, bradykinesia, gait impairment, bulbar palsy, dementia and a characteristic supranuclear ophthalmoplegia. It is a significant cause of parkinsonism and its etiology remains obscure. The case of a patient from Santa Catarina who presented definite clinical evidences of this syndrome is reported. This is the first description in this southern Brazilian State, where at least 50 more patients should exist, if we may extrapolate the prevalence rate of this condition in developed countries to this well developed area of Brazil. A review of the literature was undertaken with emphasis on recent clinical and therapeutic aspects of PSP.

A clinicopathological report is presented of a British male, aged 59 years, who died after an illness of 10 years, manifested by progressive respiratory failure, ptosis, and dysphagia. At no time was there evidence of ophthalmoplegia, Parkinsonism or dementia. At necropsy the main finding was of neurofibrillary tangles in the neurons of the pontine and medullary reticular formation, with particularly severe involvement of the nucleus ambiguus, dorsal motor nucleus of the vagus and nucleus tractus solitarius. Morphologically, by light and electron microscopy and immunostaining, the tangles were similar to those of other neurofibrillary degenerative diseases. Although similar in some respects to progressive supranuclear palsy and amyotrophic lateral sclerosis of the Guam type, the combination of clinical and neuropathological features suggest that this is a distinct disease entity.

We report the clinical and neuropathological findings in an autopsy case of progressive dementia, Parkinsonism, pseudobulbar palsy and supranuclear ophthalmoplegia. Since 70 years old, this hypertensive patient developed forgetfulness, unsteady gait and festination. These symptoms rapidly worsened and he was admitted in October 1983, at age 71. He had severe dementia and showed stiff face. Voluntary vertical movement of the eyes was severely disturbed, but reflex vertical movement by the doll's head eye maneuver was not affected. Muscle tone in the limbs increased slightly, and deep tendon reflexes were hyperactive in jaw and the upper extremities. Babinski sign was negative bilaterally. Sensation and coordination remained normal. Although he was not paretic or ataxic, his movements were very slow. He could not stand by himself and easily fell backward. These clinical features resembled those of progressive supranuclear palsy except for severe dementia and rapid progression. Brain CT scan revealed marked dilatation of the lateral ventricles, prominent periventicular lucency and atrophy of brainstem and cerebral cortex. Treatment with levodopa slightly improved his movement, but difficulty in swallowing worsened increasingly. He died of hypoglycemic coma and aspiration pneumonia in September 1984, about two years after the initial symptoms. General autopsy showed severe pneumonia and atrophy of the liver. The brain weighed 1,210g. Atherosclerotic change in the cerebral arteries were mild. Coronal sections of the cerebral hemispheres revealed diffuse ischemic change and multiple small infarctions in the bilateral cerebral white matter. Cortical atrophy was observed in the cerebral hemispheres. The basal ganglia, thalamus, and pons showed status lacunaris. Atrophy of midbrain and depigmentation of the substantia nigra were observed macroscopically.

Progressive supranuclear palsy (PSP) was first recognized as a distinct morbid entity by Richardson, Steele and Olszewski a quarter century ago. Subsequent experience has confirmed and extended their original observations. PSP has become familiar as a chronic progressive disorder with extrapyramidal rigidity, bradykinesia, gait impairment, bulbar palsy, dementia and a characteristic supranuclear ophthalmoplegia. It is an important cause of parkinsonism. Its etiology remains obscure. Familial concentrations have not been observed. Some cases exhibit no oculomotor dysfunction. Dementia is usually mild. Recent neuropsychological studies have defined features consistent with frontal lobe cortical dysfunction. Seizures and paroxysmal EEG activity may occur. CT and MRI scans show midbrain atrophy early and later atrophy of the pontine and midbrain tegmentum and the frontal and temporal lobes. PET scans have shown frontal hypometabolism and loss of striatal D-2 dopamine receptors. Postmortem studies have documented involvement of both dopaminergic and cholinergic systems. Treatment remains palliative and unsatisfactory.

The syndrome of progressive supranuclear ophthalmoplegia (Richardson-Steele-Olszewski-Syndrom) and its relation to other syndromes are discussed on the basis of a number of case histories and a survey of the pertinent literature. The validity of vertical ophthalmoplegia as a pathognomonic symptom is questioned. The main symptoms are as follows: the heightened tone of the neck muscles, as a rule combined with other indications of parkinsonism and an inclination to fall down. To varying degress there are also bulbar signs and subcortical dementia. Neuropathologically the syndrome can be classed with the "multiple system degeneration" group, on which little enough is known. It remains an open question whether the syndrom of Richardson-Steele-Olszewski is a syndrome of its own or whether it is just a variety of parkinsonism.

Four pathologically documented cases of progressive supranuclear palsy are reported. Two patients exhibited severe dementia and 2 parkinsonism; none had the classic ophthalmoplegia. On retrospective analysis, clues to the diagnosis included early prominent gait disturbance, apraxia of eyelid opening in 1 patient, lack of tremor, poor response to levodopa-carbidopa, and severe rigidity with a posture of neck extension terminally in 1 patient. The clinical presentation of progressive supranuclear palsy, therefore, is not as stereotyped as previously thought, and the diagnosis can be overlooked if one adheres rigidly to the classic diagnostic criteria.

Ten autopsy cases of Progressive Supranuclear Palsy (PSP) are reported. Age at onset ranged from 16 to 67 years and the duration of illness 3 to 24 years. The clinical features were aggressive mental retardation in 4 cases with early onset, paroxysmal dysequilibrium, ophthalmoplegia, rigidity and akinesia, pseudobulbar palsy and variable degrees of dementia. Neuropathology showed widespread neurofibrillary degeneration associated with system-bound neuronal loss and gliosis in subcortical areas, particularly affecting the subthalamic nucleus, substantia nigra, brainstem tegmentum and dentate nuclei, with no or little involvement of the cerebral cortex. The distribution of the lesions and the ultrastructure of the neurofibrillary tangles made of 15 nm straight filaments (seen in one case) in PSP are different from postencephalitic parkinsonism, Guam Parkinson-dementia complex and brainstem affection in (pre)senile dementia. Post-mortem biochemical analysis of two brains disclosed severe reduction of tyrosine hydroxylase, the key synthetic enzyme of the catecholamine pathway, not only in the nigrostriatal system as seen in Parkinson's disease, but in most areas of the brain-stem and limbic system. The implication and possible pathogenic and therapeutic significance of these biochemical findings are discussed. The etiology of PSP and its nosological position within the degenerative extrapyramidal disorders remain unknown.

In one of two siblings a clinical disorder was described, consisting of a slowly progressive juvenile parkinsonism with extensor plantar responses, external ophthalmoplegia with severe ptosis and a motor and sensory polyneuropathy. The younger sibling had only juvenile parkinsonism, Unilateral ptosis and a motor and sensory polyneuropathy. Their father was neurologically normal except for a unilateral ptosis. There did not seem to be consanguinity in this family.

The authors report the clinical, instrumental and histopathological data observed in a 27 year old man, who died 20 months after the onset of a rapidly progressive neurological syndrome referable to a multitopic brain damage. The clinical picture, which at its fully developed stage was represented by supranuclear ophthalmoplegia, cerebellar ataxia, akinetic-rigid parkinsonism with axial dystonia and dementia, appeared consistent with the diagnosis of P.S.P. The histological examination showed degenerative changes of varied degree in the cerebellum, the brain-stem and the basal ganglia, but the neurofibrillary tangles characteristic of P.S.P. were not found, either with electron-microscopy. The case presented considerable difficulties regarding its nosological classification. Nevertheless, the lack of neuropathological findings of storage disease as well as the particular location of the degenerative lesions have induced the authors to consider it as an atypical form of sporadic O.P.C.A. in the field of M.S.A.

We report a patient with mitochondrial encephalomyopathy presenting parkinsonism, as well as her brother who had ataxia but not parkinsonism. Both patients had myopathy, deafness, and insulin-dependent diabetes mellitus. The proband was a 55-year-old woman, who has developed progressive difficulty in walking and slowness of movement since 53 years of age, becoming bed-ridden at 55. Neurological examination revealed mental impairment, a masked face, Myerson's sign, vertical supranuclear ophthalmoplegia, and severe sensorineural deafness, hypokinesia, rigidospasticity, and weakness of the extremities. But tremor and cerebellar ataxia were absent. Her 48-year-old brother gradually developed weakness of the lower extremities and drunken gait over a few years. On neurologic examination, vertical supranuclear ophthalmoplegia, moderate sensorineural deafness, and cerebellar ataxia were present, but parkinsonism was absent. Three other siblings were reported to have died in early childhood. Cranial MR imaging showed cerebral atrophy and mild atrophy of the cerebellar vermis as well as mild periventricular hyperintensities in T2-weighted images in both patients. However, no infarcts were seen. Laboratory investigations revealed slightly elevated lactate and pyruvate levels in the proband and elevation of pyruvate in her brother. A biopsy specimen obtained from the quadriceps muscle showed ragged-red fibers with modified Gomori trichrome staining, and a decrease of complex I+III and complex II+III activity in the proband. Mitochondrial DNA (mtDNA) analysis using the polymerase chain reaction and restriction enzyme Apa I showed a point mutation in the tRNA(Leu)(UUR)) gene (an A to G transition at nucleotide 3243) in both patients.(ABSTRACT TRUNCATED AT 250 WORDS)
