Progressive supranuclear palsy, first described as clinical entity by Steele, Richardson and Olszewski, is a degenerative disorder of the central nervous system. Besides progressive supranuclear oculomotor disturbances, other characteristic signs are pseudobulbar paresis, axial rigidity, gait disturbances and subcortical dementia. Misinterpretation in the early stage as Parkinson's disease is frequently seen. A causal therapy is still missing.

Nine cases of progressive supranuclear palsy are reported in this paper. There are 6 males and 3 females in this series. The average age at admission was 62 years. The clinical features of those cases are: (1) onset at the presenile with gradual progression, (2) supranuclear vertical ophthalmoplegia, especially downgaze paresis, (3) disarthria, (4) gait disturbances, (5) dystonia and rigidity of the limbs, (6) clumsiness and ataxia, (7) masked face, (8) bilateral pyramidal signs and (9) mental disturbances. The CT scan in this series showed dilatation of the ventricular system, enlargement of the Sylvius fissure and cortical sulci. There was also enlargement of quadrigeminal and cisterns in the CT scan. The CT diagnosis were cerebral atrophy in 9 cases and brainstem atrophy in 8 cases in this series.

We systematically videotaped eyelid movements in a community-based series of 38 patients with progressive supranuclear palsy (PSP). Ten patients (26%) had blepharospasm, "apraxia" of lid opening and/or "apraxia" of lid closing. These patients as a group had more severe upgaze paresis but no greater disease duration than the patients without supranuclear lid dysfunction. Patients used a variety of synkinetic movements to overcome lid-movement abnormalities. One patient displayed "slow blinks," a phenomenon not previously described in PSP. Blink rate in PSP, 3.0/min, was markedly lower than that in patients with Parkinson's disease (PD), 12.5/min, and patients with PSP but not PD increased their blink rate during command versional eye movements.

A number of cortical and subcortical areas are involved in the control of saccades and smooth pursuit, and lesions affecting these areas result in various ocular motor syndromes. Most of these syndromes are relatively subtle and have to be ascertained using recordings, because other brain areas may largely take over the function of a damaged area. Anterior cortical, posterior cortical, large and bilateral cortical, subcortical and degenerative cerebral lesions are successively reviewed. In the anterior part of the cerebral hemisphere, the frontal eye field (FEF), supplementary eye field (SEF) and prefrontal cortex (PFC), i.e. area 46 of Brodmann, control eye movements. The FEF appears to be principally involved in the control of intentional saccades, in particular those made with a retinotopic reference system, and in smooth pursuit. The SEF could control saccades made with a spatiotopic reference system, and sequences of saccades (requiring a temporal working memory). The PFC could control the inhibition of unwanted reflexive saccades, and be involved in spatial memory used for programming all types of memory-guided saccades. In the posterior part of the cerebral hemisphere, the parietal eye field (PEF) is involved in the triggering of reflexive visually guided saccades, and the middle temporal (MT) and medial superior temporal (MST) areas in smooth pursuit. Acute and large unilateral lesions usually result in transitory ipsilateral conjugate eye deviation. Bilateral lesions affecting both the FEF and the PEF result in severe saccade and smooth-pursuit paresis, whereas bilateral posterior temporoparietal lesions result in Balint's syndrome, consisting of both eye movement and visual-attention abnormalities. Subcortical lesions also result in various eye movement abnormalities, which have been little documented to date. Lastly, degenerative cerebral diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, progressive supranuclear palsy and corticobasal degeneration result in more or less severe eye movement disturbances. Eye movement recordings may contribute to early differential diagnosis of some of these degenerative diseases.

We report two patients, with postural instability and dystonic parkinsonism whose adjunctive disabling feature was blindness due to an inability to reopen the eyes after voluntary closure of the eyelids, as in apraxia of lid opening (ALO). Supranuclear downgaze paresis permitted the diagnosis of progressive supranuclear palsy (PSP) in one case. Electromyographic studies showed a loss of normal reciprocal inhibition between the levator palpebrae and the pretarsal portion of the orbicularis oculi, with a cocontraction of these two antagonist muscles. The evoked blink reflex, tested with the paired shock technique, showed enhanced recovery of R2 response. Botulinum toxin A injections directed toward the junction of the preseptal and pretarsal parts of the palpebral orbicularis oculi muscle improved eyelid motility in both patients. Successive static and dynamic balance training and development of compensatory strategies for visual scanning deficits reduced gait imbalance, the number of falls, and the disability level as measured on the Northwestern University Disability Scale.

We report a 61-year-old Japanese man who died of complications of esophagus cancer surgery. He was well until his 55 years of the age, when he had an onset of speech disturbance and hand writing. He was seen by a neurologist who prescribed Menesit 600 mg/day. His symptoms improved with this medication. In 1993, three years after the onset, he started to show gait disturbance and easy to fall. In 1995, he noted difficulty in eye opening. He visited our clinic on October 26, 1996. On examination, he showed vertical gaze paresis, masked face, nuchal rigidity, small step gait, freezing phenomena, and festination. His mental status was normal. He was treated with 800 mg/day of Menesit, 800 mg/day of L-dops, and 10 mg/day of bromocriptine with little improvement in his symptoms. Cranial CT scan revealed some dilatation of the third ventricle. Subsequent clinical course was one of the slow progression of his parkinsonism. In September of 1997, he noted difficulty in swallowing. He was admitted to the gastrointestinal service of our hospital on October 14, 1997. On admission, neurologic status was essentially similar to the previous one, but he showed more advanced state of his parkinsonism. Upper gastrointestinal series revealed a mass lesion of about 11.5 cm in length protruding into the lower esophagus lumen. Subtotal esophagus resection including the mass was performed on December 2, 1997. The stomach was elevated for anastomosis with the upper esophagus. No metastases were found in the mediastinum except for two lymph nodes in the para-esophageal region. The subsequent course was complicated by marked elevation of GOT, GPT, LDH, total bilirubin as well as direct bilirubin, alkaliphosphatase, and amylase starting in the evening of the surgery. On December 7, leukocytosis and pneumonic shadow were seen involving his right lung. On December 10, he developed cardiopulmonary arrest. He was once resuscitated; however, he developed cardiac arrest again seven hours later and pronounced dead. He was discussed in a neurologic CPC. The chief discussant arrived at the conclusion that the patient had PSP and the cause of the death was ascribed to circulatory disturbance to the liver. The discussant also thought that the terminal course was complicated by cholangitis or cholecystitis, sepsis, and pulmonary embolism. Surgical specimen of the esophagus tumor revealed carcinosarcoma. Postmortem examination revealed yellowish discoloration of the peritoneum and mesenterium, and accumulation of clouded ascites indicating the presence of peritonitis. Inflammatory change extended to the mediastinum. On microscopic examination, various kinds of bacilli and candida spores were seen. The liver was enlarged and a perforation was noted in the gallbladder causing biliary necrosis in the adjacent liver. An extensive infarct was seen in the left lobe of the liver; this was found to be due to obstruction of the hepatic artery at the site of the duodenohepatic mesenterium and obstruction of intrahepatic portal vein secondary to retrograde intrahepatic cholangitis in the left lobe. A piece of surgical threads was seen adjacent to the hepatic artery; foreign body granulomatous reaction was seen surrounding the surgical thread. The rupture of the gallbladder appeared to be due to the obstruction of the left branch of the hepatic artery. Neuropathologic examination revealed extensive degeneration of the pallidum, the substantia nigra, and the subthalamic nucleus and presence of neurofibrillary tangles in the remaining neurons. The neuropathologic findings were consistent with progressive supranuclear palsy, although the pathologic changes in the midbrain tegmentum was only mild gliosis.

We report a 77-year-old Japanese man with progressive gait disturbance. He was well until his 71 years of the age (1992), when he noted an onset of disturbance in his speech, which was followed by difficulty in using his left hand. He did not attempt to use his left hand afterwards. He started to fall down in the spring of 1994. He was admitted to our service on October 6, 1994. Neurologic examination revealed an alert and oriented man. He showed limb-kinetic apraxia in his left hand with anosognosia for his apraxia. Vertical gaze was impaired. He walked in small steps. He had moderate axial and limb rigidity. He had no weakness, ataxia, or tremor. Deep tendon reflexes were normal. Plantar response was flexor. Sensation was intact. His gait had progressively become worse and he was admitted to another hospital in April of 1996. At that time he was disoriented to time. He was only able to walk a few steps with support. He continued to show limb-kinetic apraxia in his left hand. He developed dementia and dysphagia and he expired on October 27, 1998. He was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that the patient had corticobasal degeneration. Most of the participants agreed with this diagnosis, but a few of them thought that progressive supranuclear palsy would be more likely. Post-mortem examination revealed no gross cortical atrophy. The right hemisphere was kept frozen for future biochemical analysis. The left precentral gyrus showed spongy changes, neuronal loss and gliosis. The pallidum, putamen, and the subthalamic nucleus were unremarkable, however, neurofibrillary tangles were seen in the subthalamic nucleus. The substantia nigra showed only slight neuronal loss; neuronal pigments were well retained. A few neurofibrillary tangles were seen in the remaining neurons. The cerebellar dentate nucleus showed grumose degeneration. Gallyas-Braak staining revealed many tuft-shaped astrocytes in the precentral gyrus. Pathologic diagnosis was progressive supranuclear palsy. Some participants thought that this diagnosis was unacceptable, because the pathologic changes in the substantia nigra, globus pallidus, and the subthalamic nucleus, which were usually severely involved in PSP, did not show typical changes of PSP. In addition, the predominant clinical feature was limb-kinetic apraxia, although he showed vertical gaze paresis and parkinsonian gait, which could also be seen in corticobasal degeneration. There was a big discussion among participants with regard to the diagnosis.

We reported a 74-year-old male case of progressive supranuclear palsy (PSP) who responded to tandospirone citrate, a serotonin receptor (5-HT1A) agonist. The patient manifested postural instability and gait disturbance at 71 years. Additionally, he showed vertical gaze paresis, regidity of the neck, extremities and trunk, bradykinesia and mild cognitive impairment. A brain MRI revealed moderate atrophy of bilateral frontal/temporal lobes and of midbrain tegmentum one year after the onset. The patient had been diagnosed as PSP and treated with L-DOPA. However, L-DOPA therapy showed only transient response for a few months. His symptoms deteriorated gradually, and he became unable to sit, stand up or walk by himself. Tandospirone citrate was additionally administered at 30 mg/day. Rigidity and bradykinesia were remarkably improved in two weeks after the start of tandospirone treatment. He became able to stand up and walk a short distance with supports in four weeks. Cognitive disturbance was also slightly improved. Tandospirone citrate was effective on our case of PSP, especially on rigidity. Our findings suggest that combination of levodopa and tandospirone citrate is a useful therapy for PSP.

We report a 75-year-old, right-handed man, presenting with supplementary motor area (SMA) seizure. The patient had suffered from frequent attacks of transient inability to speak and move without loss of awareness. On admission, he presented with vertical gaze paresis, axial rigidity, paratonia of extremities and gait disturbance. The attacks were preceded by discomfort on the head, followed by inability to move the whole body and arrest of vocalization with tonic posture and exaggerated breathing. Consciousness and cognitive function were preserved throughout the attacks. Electroencephalography recorded intermittently slow theta waves in the bifrontal regions. Brain MRI showed atrophy of the midbrain tegmentum with lacunar state suggesting progressive supranuclear palsy. SPECT with 123I-iomazenil revealed decreased uptake in the medial frontal areas including SMA, bilaterally. The seizures resolved completely following treatment with carbamazepine. Based on clinical features and neuroimagings, we speculated that the negative motor area within SMA was responsible for his seizure. Physicians should keep in mind that SMA seizure comprising negative motor phenomenon can occur in the elderly.
