An autopsy case of progressive supranuclear palsy (PSP) associated with central pontine myelinolysis (CPM) is reported. A 73-year-old male patient suffered from gait disturbance for about 5 years. The clinical features were characterized by gradual development of supranuclear ophthalmoplegia, tremor, bradykinesia, rigidity, neck dystonia, dementia and pseudobulbar palsy at the advanced stage of his illness. Treatment with levodopa did not improve his neurological signs and symptoms. PSP or multiple system atrophy was considered as a clinical diagnosis of the patient. He died of pneumonia, acute pancreatitis and liver dysfunction in November 1985. The main neuropathological findings were neuronal loss and gliosis with neurofibrillary tangles of globose type in the globus pallidus, subthalamic nucleus, substantia nigra and dentate nucleus, and at the base of the pons, bilateral and symmetrical demyelination was found. In addition, myelin staining revealed circumscribed pallor in the cerebral white matter. The histologic diagnosis was PSP associated with CPM. An association of PSP with CPM is rare in the elderly and possible etiologic factors of both diseases were discussed.

A 13-year-old boy was the victim of attempted strangulation. His condition had returned to normal by the sixth day after the assault; however, from the seventh day, choreoathetosis, dystonia, and marked pseudobulbar paralysis developed in the boy. The computed tomographic scans and T2-weighted magnetic resonance images that were obtained at this time revealed low-density and high-signal intensities in the region of the bilateral putamen and caudate nucleus. These symptoms and the changes in his computed tomographic scans and magnetic resonance images subsided gradually during a 2-month period. Sequential analysis of the cerebrospinal fluid for gamma-aminobutyric acid and dopamine concentrations during his illness revealed reciprocal changes with normal recovery. Because of the delayed onset of neurological changes and the cerebrospinal fluid showing reversible symptoms, the delayed encephalopathy after strangulation had been related to the biochemical alterations that followed anoxia in the vulnerable basal ganglia.

A 13-year-old boy was the victim of a strangulation attempt. His behavior was normal by the 6th day after the assault. However, from the 7th day, he developed choreoathetosis, dystonia and marked pseudobulbar palsy. CT and T2-weighted MRI at this time revealed a low density and high signal intensity in the region of the bilateral putamen and caudate respectively for the first time. Thereafter, these symptoms and changes in CTs and MRIs subsided gradually over two months. Sequential analysis of CSF for GABA and dopamine during illness revealed reciprocal changes each other with normal recovery. Because of delayed onset of neurological changes, and findings of CSF with reversible symptoms the delayed encephalopathy after strangulation is probably related to biochemical alteration secondary to anoxia in vulnerable basal ganglia.

Two cases of progressive supranuclear palsy (PSP) with palilalia were presented. Case 1: A 64-year-old woman was in good health until age 62 when she noted clumsiness in walking. Subsequently, forgetfulness, abrupt falls and difficulty in swallowing developed. At the age of 63, she tended to repeat same words in conversation. On admission, neurological examination revealed mental deterioration (Hasegawa's scale 19), unsteady emotional state, supranuclear vertical gaze palsy, pseudobulbar palsy, nuchal dystonia, pyramidal tract signs and extrapyramidal signs. Although spontaneous speech production was reduced, she could answer to questions with compulsive repetition of a phrase or word. She always repeated twice or three times without stuttering, logoclonus or "palilalie aphone". Case 2: A 68-year-old, right-handed woman noted double vision since about one year ago. Subsequently, she developed slowness of voluntary movement, forgetfulness and difficulty in walking. Neurological examination showed similar signs as Case 1. She was not palilaic on examination, however we found the description of her palilalia on nurse's working records. Palilalia was not present so constantly as Case 1, but continued for about a year. We suppose that palilalia is not a rare phenomenon in PSP. Although the pathogenesis of palilalia is unknown at present, we speculate the combination of extrapyramidal sign, pseudobulbar palsy and dementia may most contribute the pathogenesis of palilalia on PSP.

Progressive supranuclear palsy (PSP) is a syndrome of supranuclear ophthalmoplegic palsy, pseudobulbar palsy, rigidity of the limbs, nuchal dystonia, and dementia in which the gaze palsy is the hallmark of the disease. Most neurologists are reluctant to consider the diagnosis unless visual problems exist. Since the earliest complaints of PSP are said to be variable and subtle, accurate diagnosis is often delayed and initial pathologic changes of the disease not well studied. Two patients came to autopsy with dementia, gait disturbances, and/or dysarthria but no eye findings by history or physical exams. Symptoms had been attributed to metastatic cancers. At autopsy prominent globose neurofibrillary tangles with variable cell loss, microglial nodules, and neuronophagia were found in the locus ceruleus, third cranial nerve complex, nucleus supratrochlearis, nucleus centralis superior, and nucleus basalis of Meynert with mild pallor of the globus pallidus, mild cell loss in the dentate nucleus of the cerebellum, and sparing of the superior colliculus. The diagnosis of early PSP was made. These cases serve to 1) detail the more limited neuropathologic changes in early PSP, 2) reemphasize that the earliest clinical symptoms of PSP are not gaze palsies, and 3) remind clinicians to consider PSP in their differential diagnosis in patients with gait disturbances, dementia, and/or dysarthria, and 4) document PSP in association with carcinoma in two cases.

The clinical picture of progressive supranuclear palsy is relatively constant, including supranuclear ophthalmoplegia, pseudobulbar palsy, axial dystonia in extension, parkinsonian signs, postural instability and dementia. A case is reported, which is unusual in having flexor dystonia of the neck and marked signs of lower motor neuron involvement.

Progressive supranuclear palsy (PSP) is a distinct clinicopathologic entity characterized by supranuclear ophthalmoplegia, pseudobulbar palsy, axial dystonia in extension, and subcortical dementia. Although relatively rare, PSP is disabling, thus rehabilitation techniques and management are indicated in nearly every case. This report describes the neurologic presentation, rehabilitation management, and outcome of treatment of a patient with PSP during a 12-month period. The patient required thorough neuromuscular, neuropsychological, speech, swallowing, vision, and social service evaluations prior to the implementation of a rehabilitation program. Therapeutic rehabilitation techniques focused on limb coordination activities, tilt board balancing, ambulation activities, and activities to improve route finding and visual scanning ability. Prism lenses were introduced to compensate for deficits in vertical eye movements. Treatment improved the patient's functional status. Later, as the patient's neurologic status deteriorated, it became necessary to educate the family and caretakers in the ongoing rehabilitation management of the patient.

Eleven cases of "pure akinesia without rigidity and tremor and with no effect by L-dopa therapy" were first reported by Imai in 1980. Three cases were added by Hayashi and Hayashi (1983). However there have been so far no autopsy cases, remaining the nosological position of this syndrome uncertain. The authors have had an opportunity of observing the third case in the report by Hayashi and Hayashi for 8 years and autopsy was done as well. Case report The patient was a female farmer. On account of postural-reflex troubles, the pulsion phenomenon and feet freezing, which had progressed since the age of 54, she easily tumbled over. Eight years after the beginning of those symptoms, vertical oculomotor palsy, pseudobulbar palsy and dementia were added; she was diagnosed as a progressive supranuclear palsy. Before this diagnosis, her illness was being regarded as "pure akinesia without rigidity and tremor and with no effect by L-dopa therapy". Neck dystonia was not observed even in the terminal stage. She died at the age of 65. The total clinical course was about 11 years. Pathological observation The brain weighed 1,170 g before fixation. Marked atrophy of the subthalamic nucleus, globus pallidus and pontine tegmentum was observed. The substantia nigra was shown to be severely depigmented. Microscopically, loss of neurons and gliosis were seen in the subthalamic nucleus, globus pallidus, substantia nigra, hypothalamus, superior colliculus, central grey matter, brain stem reticular formation, cerebellar dentate nucleus, etc. The characteristic finding was the appearance of neurofibrillary tangles in these regions.(ABSTRACT TRUNCATED AT 250 WORDS)

Reviewing the literature since recognition of progressive supranuclear palsy (PSP) as a clinicopathological entity 20 years ago, the present state of knowledge is delineated. The etiology of PSP is still unknown. The clinical hallmarks are supranuclear palsy of vertical gaze, axial dystonia in extension and pseudobulbar palsy with marked dysarthria and dysphagia. Accessory features include subcortical dementia, mental, extrapyramidal, pyramidal and cerebellar symptoms. PSP is a disease of the presenium (average age at onset, 59.6 years) with a male preponderance (60% men). The onset is insidious with vague complaints of dysequilibrium (60%), mental changes (46%) and disturbed vision (21%), often preceding abnormal neurological findings. The important borderland and main differential diagnosis is parkinsonism. However, in PSP, responsiveness to antiparkinsonian agents is poor and progression is rapid and fatal within few years (average survival time, 5.7 years). Promising diagnostic tools at present include CT-scanning and neuro-otologic and -ophthalmologic examination. Neuropathological findings, confined to specific diencephalic, brainstem and cerebellar nuclei, include neurofibrillary tangles (ultrastructurally different from those seen in other CNS disorders), neuron loss and gliosis. The importance of research on neurocytochemistry, brain ultrastructure and immunology in the current investigation of PSP is outlined.

Progressive supranuclear palsy (PSP) is characterized by supranuclear ophthalmoplegia mainly affecting vertical gaze, nuchal dystonia in extension, pseudobulbar palsy, and mental changes. The literature on PSP has been neurologically oriented whereas the psychiatric aspects have been relatively neglected. A review of the literature shows that psychiatric disturbance in PSP is common but with no characteristic pattern. Cognitive impairment, nonspecific affective and behavioral disturbances are commonly found, whereas frank psychosis or bipolar disorder are rare. Misdiagnoses with psychiatric disorders are common and a heightened awareness of the condition is necessary for early diagnosis.
