A Japanese woman, aged 42, was admitted because of paroxysmal attacks consisting of paresthesia of the left face, tremor in the right hand, epigastric pain and urinary incontinence. A year prior to the admission, she noticed some difficulty in writing, dysarthria and unsteadiness of walking. These symptoms had been persistent since then. At the end of March, 1991, these symptoms rapidly worsened, and she fell down frequently. She also experienced pain behind both eyes, numbness in her left fingers and toe, urinary frequency and the above-mentioned attacks. Neurological examination disclosed bilateral internuclear ophthalmoplegia and upbeating nystagmus on upward gaze, titubation in the head, scanning speech, dysmetria in all limbs, exaggerated reflexes in jaw and both legs, bilateral extensor plantar reflexes and ankle clonus. SEP showed delayed cortical response with stimulation of the median nerves bilaterally and of the right posterior tibial nerve. P40 was absent with the left posterior tibial nerve stimulation. VEP was normal. T2-weighted image of MRI showed multiple high intensity areas located around the third ventricle, crus cerebri and the right upper part of the pons. The diagnosis of multiple sclerosis was made. Each paroxysmal attack started with numbness in the left face and burning sensation in the neck. Almost simultaneously tremor in the right hand began. The surface EMG showed the rhythmic contractions in the dorsal hand muscles and wrist extensors at a frequency of 6-7 Hz, and sometimes it revealed synchronized contractions of finger flexors and the dorsal hand muscles. A few seconds later she felt painful sensation in the epigastric region, and the tremor gradually increased in its intensity.(ABSTRACT TRUNCATED AT 250 WORDS)

A 59-year-old man developed a staggering and wide based-gait in July 1990. Dysarthria, hearing loss, vexation and disturbance of memory appeared in January 1991. He consulted our clinic in May 1991, and cerebellar ataxia, neurogenic bladder, and cerebellar atrophy on brain CT were noted. Subsequently, he was followed as OPCA. Brain and spinal cord MRI (T2 and proton weighted images) revealed hypointensity on the surface of the Sylvian fissure, cerebellum, brainstem and spinal cord. We diagnosed this case as superficial siderosis because of the clinical course, i.e. cerebellar ataxia, dementia and sensorineural hearing impairment, and specific findings on MRI. We consider this case idiopathic superficial siderosis because the origin of the bleeding source was unknown. IMP-SPECT showed low perfusion in the cerebellum and frontal lobe where hemosiderin was heavily deposited. RI cisternography revealed a disturbance of CSF absorption even after 48 hours. The basic rhythm on EEG was slow alpha band with sporadic theta waves dominantly in the frontal lobe. His central conduction time on ABR and SEP was delayed, OKN was poorly elicited and ETT exhibited a staircase pattern. The physiological results as well as the clinical manifestations of the present case suggest that hemosiderin deposit on the surface of brain and spinal cord caused serious damage to the underlying structures.(ABSTRACT TRUNCATED AT 250 WORDS)

This report describes a patient with degenerative type of progressive myoclonus epilepsy (PME), who showed slowly progressive deterioration of the central nervous system; intellectual impairment, dysarthria, and involuntary movements, particularly action myoclonus and dystonia. The patient was a 19-year-old woman who had no hereditary factors. At the age of 4, she developed action myoclonus in the upper limbs bilaterally. Her condition became gradually worse, and at the age of 15, she was admitted to our hospital because of involuntary movement in the upper limbs. First physical examination revealed mild mental retardation, action myoclonus, dystonia, and delayed adolescence. As giant SEP characteristic of PME and Ramsay Hunt syndrome was found, she was tentatively diagnosed as having Ramsay Hunt syndrome without epilepsy, and delayed adolescence. Now, she is 19 years old, and unable to walk alone because of involuntary movements and paralysis. But she has not developed epilepsy. As she has not been compatible with progressive myoclonus epilepsy (PME) and progressive myoclonic ataxia (PMA) classified by Marseille Consensus Group, she has been diagnosed as having an atypical PME syndrome.

We report a 53-year-old right handed woman with a 5-year history of slowly progressive clumsiness of her right hand. Neurologic symptoms was otherwise unremarkable except for mild dysarthria. Brain CT and MRI revealed a focal atrophic change in the left precentral gyrus. She was thought to have the primary progressive limb-kinetic apraxia. Electrophysiological studies were performed to explore physiologic mechanism of her apraxia. Surface EMG revealed co-contraction of antagonistic muscles in her right upper extremity with rhythmic myoclonic discharges. C-reflex was positive after median nerve stimulation only on the affected side. SEPs elicited by the median nerve stimulation were not enlarged and the SEP recovery curves showed no abnormal facilitation or inhibition. In addition, the premyoclonus spike was demonstrated by Jerk-locked averaging. Transcranial magnetic stimulation using double pulse paradigm revealed a decrease in the level of cortico-cortical inhibition on the motor cortex in the affected side. Median nerve stimulation given prior to the transcortical magnetic stimulation on the size of the magnetic evoked potential (MEP) revealed abnormal facilitations on the affected side, especially at conditioning-test interval of 60-80 ms. Therefore, our results indicate increase in the excitability of motor cortical neurons in primary progressive limb-kinetic apraxia, likely due to a decreased excitability of cortico-cortical inhibitory mechanism as a result of focal degeneration of cortical neurons.

Spinocerebellar ataxia is a group of diseases with autosomal dominant inheritance heterogenous both clinically and genetically. So called dynamic mutations underlie most these nosological units. The clinical patterns of various SCA types have not yet been defined completely. The purpose of the present report was description of the typical symptoms and signs of type 1 SCA. Seventeen patients from 13 families (M-2, F-15) were studied clinically in detail. The diagnosis was confirmed by DNA analysis. The assessment included neurological status, cognitive functions, the results of EEG, EMG, SEP, VEP, BAER and MRI examinations. The pedigrees indicated autosomal dominant inheritance pattern. The mean age at onset was 35.5 +/- 6.8 years (range 23-45 years) and it suggested negative correlation with the number of CAG repetitions. Cerebellar syndrome limb and truncal, ataxia and dysarthria was present in all cases. Six patients had nystagmus, 3 had slow saccades, 2 had gaze limitation upward, and lateral and 6 had dysphagia. Signs of pyramidal system involvement were found in 10 cases, one had athetotic movements, one had orthostatic hypotension. Two patients had dementia features, 9 had some decline of intellectual functions, mainly with difficulties of memorization, learning and concentration. In 16 cases MRI demonstrated vermis atrophy and atrophy of cerebellar hemispheres, 14 had fourth ventricle dilatation, 8 had flattening of pons base, 8 had narrowing of cervical spinal cord, 8 had dilated CSF spaces over frontal lobes and in 6 cases lateral ventricles were dilated. Electrophysiological peripheral nervous system investigations showed in 16 cases long-standing damage to the motor and sensory peripheral neurons at the level of nerve trunks, more pronounced in sensory nerves. In 13 cases peripheral neuron damage was subclinical. SEP showed in all patients disturbed function of ascending sensory pathways at peripheral and spinocortical levels.
