H. I., a housewife aged 55 years, began feeling a gait disturbance at 48 years old. After this she had incoordination of arms, dysarthria and tremor of hands. Aged 54 years, she could not stand up by herself. In addition to these neurological signs she had a change of character, such as losing control of herself, unreservedness and unceremoniousness, and slight disturbance of intelligence. She died at the age of 55 years about seven years after the onset. Histopathologically, noticeable changes were observed on the medulla oblongata, pons and cerebellum; the severe neuronal loss of the pontine nuclei and the olivary nuclei with demyelination and gliosis of the cerebellopetal fibers. Especially a great deal of lipofuscin granules in the nerve cells of the frontal and temporal lobe were observed. In the substantia nigra some pigmented cells were deleted. This case was diagnosed as olivo-ponto-cerebellar atrophy clinico-histopathologically. We discussed conserning the etiology of the changes of personality and slight disturbance of intelligence in relation to histopathological changes. It is speculated that the mental disorders are due to the degeneration of the nerve cells in the frontal and temporal lobes.

A case with cortico-basal degeneration was reported with special reference to the immunohistochemical study. A 59-year-old housewife noted tremor and clumsiness of her left hand. On the initial examination she showed the hyperreflexia of the upper extremities and jaw jerk, parkinsonian symptoms such as Myerson sign, parkinsonian gait and rigidity in the left arm. She showed pronounced forced grasping in the left hand. At the age of 60 she showed a WAIS scale with verbal IQ of 99 and performance below the scale. She could not copy hand postures. Tremor was aggravated by action or anxiety, more prominent on the left hand. There was some incoordination on the finger-nose testing of left arm and on the knee-heel testing of both legs. She also showed homolateral dyskinesia. She had a left Babinski sign and sensory testing was normal. A CT scan showed slightly enlarged ventricles (Fig. 1). At the age of 61 she could not understand simple requests and speak few words spontaneously, showing severe dysarthria. There were palilalia and motor impersistence. CT scan showed more widening of the lateral ventricles. At the age of 62, she had lingual dyskinesia and tapping on her upper lip provoked myoclonic jerk on her arms. She died of pneumonia at the age of 65 years, 6 years from the onset. The brain weighed 1190 g. There were bilateral old subdural hematomas on the right parietal and occipital lobe and the left parietal lobe. There was atrophy of frontal and superior parietal region.(ABSTRACT TRUNCATED AT 250 WORDS)

A young child with Hallervorden-Spatz syndrome is presented. She was well until 8 years of age when she lost interest in activities and her school performance declined. At age 11 years, she began having episodes of blepharospasm, accompanied by bilateral ptosis and occasional episodes of oculogyric crisis. By age 12 years, her motor coordination had declined and she began to exhibit evidence of dementia, dystonia, dysarthria, and tremor. Motor incoordination, dystonia, and tremor progressed until the patient was wheel-chair-bound. Multiple tests were performed, including metabolic studies, magnetic resonance imaging, bone marrow biopsy, and electron microscopy of the buffy coat. Both bone marrow and buffy coat revealed inclusions in the cytosomes which were granular and osmiophilic. To our knowledge, this is the third case report of inclusion bodies found in patients with manifestations of Hallervorden-Spatz syndrome. These findings suggest that obtaining a buffy coat and bone marrow biopsy may aid in the diagnosis of Hallervorden-Spatz syndrome and ultimately provide information regarding etiology.

A 37-year-old housewife, who had physical characteristics of cerebral gigantism, such as the tall stature, acromegaly, macrocephalia, high arched palate and antimongoloid slant, developed cerebellar ataxia and dysarthria. Her mother, uncle and grandmother were also reported to have slowly progressive gait disturbance. Her mother was also tall. Endocrinological studies failed to show any definite abnormality. CT and MRI revealed remarkable cerebellar atrophy. Though cerebral gigantism is often associated with clumsiness and incoordination, the etiology of the ataxia is poorly understood. This case indicates that the ataxia in cerebral gigantism may be, at least partly, caused by cerebellar atrophy.

Because of its interactions at N-methyl-D-aspartate and haloperidol specific sigma receptors, dextromethorphan may have symptomatic or protective effects in Huntington's Disease (HD). Escalating doses of dextromethorphan in 11 HD patients produced side effects of dysarthria, rash, and incoordination. At maximum doses, performance declined on a variety of measures of HD, including functional rating scales and quantitative exam scores, consistent with dose-related side effects. Windows of symptomatic benefit were not found. Serum levels of dextromethorphan and its metabolites, including the active compound dextrorphan, showed atypical relationships to dose and side effects, suggesting complex pharmacokinetics. Although not beneficial symptomatically, further trials of dextromethorphan as protective therapy in HD may be warranted.

With the great progress in the imaging technique of cerebro-cerebellar perfusion and metabolism, it has been revealed that supratentorial cerebrovascular disorders often cause some reduction of contralateral cerebellar blood flow and metabolism. The phenomenon, termed crossed cerebellar diaschisis (CCD), is interpreted to be brought about by transneuronal deactivation of cerebellum via the corticopontocerebellar pathway and usually not to accompanied by limb-incoordination. We have experienced 2 cases presenting ataxia clinically and CCD in positron emission tomography (PET) which are thought to be caused by the interruption of two distinctive neural pathways, the corticopontocerebellar and cerebellorubrothalamic pathways. Case 1 was a 34-year-old housewife with cerebral infarction which magnetic resonance imaging disclosed in the left parietal cortex and subcortical white matter. She showed mild right-sided hemiataxia featured by dysarthria, hypermetria, dysrhythmia, decomposition, dysdiadochokinesis and rebound phenomenon. Cheirooral syndrome, a hand-pronation sign and defects of combined sensation were present on the right but not accompanied by any disturbances of deep sensation. PET with 15O-labeled CO2 and O2 demonstrated the left frontoparietooccipital and contralateral cerebellar hypoperfusion and hypometabolism. Case 2 was a 69-year-old female suffering from aftereffects of old thalamic hemorrhage. Neurological examination revealed moderate degree of right-sided hemiataxia suggesting a cerebellar type of dysfunction like in case 1. Muscle power and sensory system were well-preserved. Brain CT revealed a small and restricted low density area in the left posterolateral thalamus indicating destruction of the Vim nucleus. PET study confirmed reduced blood flow and oxygen metabolism in the left thalamus and contralateral cerebellar hemisphere.(ABSTRACT TRUNCATED AT 250 WORDS)

A stroke with a somewhat unusual neurologic formula was correlated with a small linear high-intensity T2 focus in the lateral tegmentum of the lower third of the pons. The clinical features included dysarthria, staggering gait, incoordination of handwriting, right facial weakness, nystagmus, ocular overshoot, right appendicular ataxia, and left-sided dissociated sensory loss for pain and temperature. Lacunar lesions of the tegmentum in the region of the pontomedullary junction, while not uncommon, have not been studied pathologically and have not been reported in the magnetic resonance imaging literature, to my knowledge.

The patient, a man aged 57, was admitted to our clinic on May 1, 1987, because of severe vertigo and unsteadiness in standing. Since the age of 55 he had been suffered from hypertension and atrial fibrillation. In September, 1986, he experienced vertigo but recovered soon without therapy. On April 25, 1987, while working, he noticed severe vertigo, nausea and vomiting. He was admitted to a hospital, and then transferred to our clinic. On admission, he was alert and the mentality was normal. Slight ptosis abducent nerve paresis, hypalgesia on the forehead, nose and cheek, facial paresis of peripheral type and hypacusis were detected on the left side. No anisocoria was observed. Sweating was impaired over the left side of the face. Elevation of the soft palate was limited on the left side and the tongue deviated to the left on protrusion. Dysarthria was detected. Though there was no muscular weakness in the extremities, incoordination and dysmetria were noted in the left arm and leg. He could not stand up because of vertigo and unsteadiness. There was no sensory disturbance in the trunk and extremities. Deep tendon reflexes were well elicited and no pathological reflex was observed. These clinical manifestations, except for the ipsilateral palatal and lingual disturbances, were typical of the lateral inferior pontine syndrome caused by occlusion of anterior inferior cerebellar artery, and the lesion was clearly demonstrated by horizontal and coronal MRI. The palatal and lingual disturbances might be due to the involvements of the corticobulbar tracts of the 10th and 12th nerves after the fibers had decussated.

Three patients from two families had an unusual phenotypical variant of late-onset hexosaminidase-A deficiency. The clinical picture was dominated by spinal motor neuron involvement mimicking juvenile-onset spinal muscular atrophy. Atypical features included prominent muscle cramps, postural and action tremor, recurrent psychosis, incoordination, corticospinal and corticobulbar involvement, and dysarthria. The presence of these atypical features in patients whose lower motor neuron involvement would otherwise be consistent with juvenile-onset spinal muscular atrophy should raise the suspicion of the presence of hexosaminidase-A deficiency and GM2 gangliosidosis that can be proved by appropriate enzyme assays.
