The patients belonged to three different families and were products of consanguineous marriage. The neurological symptoms and signs in these patients began in infancy or childhood and included gait disturbance, horizontal nystagmus, distention tremor of the hands, muscular wasting and sensory impairment of the hands and legs. CT-scan and/or MRI showed atrophy of the cerebellum. Serum biochemical analyses revealed hypoalbuminemia with hyperlipidemia. There were no abnormalities in the heart, liver, kidney, gastrointestinal tract, or endocrine systems. The autopsy revealed degenerative changes in the spinal cord including posterior column and lateral pyramidal tract, as well as in the peripheral nerves and cerebellar cortex. Although we have speculated that the disease presented here would be a clinical variants of Friedreich's disease, it would make a new clinical entity because there was no report about the association to hypoalbuminemia and hyperlipidemia with spinocerebellar degeneration.

30 patients with writer's cramp were examined by a neurologist and a psychiatrist. The syndrome was frequently associated with a postural tremor. We found no evidence for a peripheral causation. Electromyographical recordings showed co-contractions of agonists and antagonists as well as individual patterns of increased muscle activity during writing. CT and MRI scans were normal in most patients. The psychiatric examination revealed a history of situational stress at the onset of the disease and also some abnormalities in the biography and personality traits. Since the latter findings were not consistently present we have no evidence that the disease is a neurotic manifestation. We consider it likely that secondary psychoreactive processes may have some significance in the individual patient.

We reported a 65-year-old man whose sister was suffering from HTLV-I-associated myelopathy (HAM) and who presented slowly progressive spastic paraparesis, sensory disturbance in the feet, tremors and cerebellar ataxia. He was also positive for serum anti-HTLV-I antibody. He first showed a head tremor at the age of 3 years. He developed a spastic and ataxic gait when aged 15 years, and it became difficult for him to walk at the age of 50 years. Examination at 65 years showed a spastic and ataxic gait and scanning speech. Hyper-reflexia and Bahinski's signs were observed. Sensation in the feet was decreased. The anti-HTLV-I antibody titer in the serum was 1:512 by the PA method, and Western blot analysis revealed bands of P19, P24, P28 and P32. Examination of the cerebrospinal fluid (CSF), including oligoclonal bands, gave normal results. The CSF was negative for anti-HTLV-I antibody. CT and MRI of the head showed cerebellar atrophy. His sister was 60 years old. She had developed a spastic gait at the age of 15 years. Sensory defects and bladder dysfunction developed when aged 35 years. Hyper-reflexia, Babinski's sign and foot clonus were observed. Sensation in the feet was decreased. The urinary residual volume was increased. Ataxia was not observed. The anti-HTLV-I antibody titer in the serum was 1:8,192 by the PA method, and Western blot analysis revealed bands of p24, p28 and p32. Examination of the CSF, including oligoclonal bands, gave only normal results.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied 18 patients with multiple system atrophy (MSA) by high field strength MRI: 6 striatonigral degeneration (SND), 4 Shy-Drager syndrome (SDS), and 8 olivo-ponto-cerebellar atrophy (OPCA). We also studied 30 Parkinson's disease (PD) and 10 age-matched controls. The diagnoses of SND, SDS, and OPCA were based on criteria after Hirayama et al (1985). Bradykinesia, rigidity, and tremor were assessed with the summed scores of the signs used as the extrapyramidal scores. The mean extrapyramidal scores were not significantly different in patients with SND, SDS, OPCA, and PD. MRI studies were performed on 1.5 tesla MRI unit, using a T2 weighted spin echo pulse sequence (TR2500 ms/TE40 ms). The width of the pars compacta signal in all subjects was measured by the method of Duguid et al (1986). Intensity profiles were made on a straight line perpendicular to the pars compacta through the center of the red nucleus on an image of the midbrain. We measured the width of the valley at half-height between the peaks of intensity representing the red nucleus and the crus cerebri-pars reticulata complex and used this measurement as an index of the width of the pars compacta signal. The mean widths of the pars compacta signal were: 2.8 +/- 0.4 mm (SND), 2.8 +/- 0.7 mm (SDS), 3.6 +/- 0.6 mm (OPCA), 2.7 +/- 0.3 mm (PD), and 4.3 +/- 0.6 mm (control). The mean widths of the pars compacta signal in PD, SND, and SDS were significantly narrower than that in the control group (p < 0.05), while the OPCA group was not significantly narrower.(ABSTRACT TRUNCATED AT 250 WORDS)

We report palilalia and acquired stuttering in a 60-year-old Japanese male with Parkinson's disease. At the age of 54, he presented with resting tremor in the hand and foot on the left, and gradual slowness in voluntary movements. Two years later, resting tremor involved the right foot, and an expressionless face and frozen gait occurred. A diagnosis of Parkinson's disease was made and treatment with L-dopa and carbidopa resulted in conspicuous improvement. At the age of 57, he developed compulsive repetitions of syllables, words and phrases, and sentences infrequently when he spoke. They have been persisting for four years. Repetitions increased in spontaneous speech while they decreased in oral reading and repetition of sentences. These repetitions in speech were symptomatologically diagnosed as palilalia and acquired stuttering. Brain CT showed slight brain atrophy, and brain MRI disclosed a few lesions indicating lacunae in the left substantia nigra, left putamen, and right internal capsule. SPECT showed a slight decrease in blood flow in the frontal lobes and basal ganglia bilaterally. Full IQ on WAIS was 105, and neither agnosia nor apraxia was detected. Palilalia and acquired stuttering, though the pathomechanism has not been clarified, have been reported to occur usually secondary to cerebral vascucular lesions and very rarely in Parkinson's disease. In the present case, they may have been produced by the parkinsonian nigro-striatal lesions. Alternatively, they may have been induced by the small vascular lesions demonstrated by MRI.

An autopsy case of ataxic form of Creutzfeldt-Jakob disease (Brownell and Oppenheimer, 1965) was reported. The patient, a 71-year-old male, noticed ataxic gait at the beginning of June in 1988, and was admitted to the Hiroshima City Hospital for the neurological examination at the end of June. He showed ataxia of the left arm and legs and diplopia. Gradually he became delirious at night. On July 16, tremor-like involuntary movement of the left hand was noticed. On July 20, he became somnolent and doubly incontinent. Myoclonus and paratonic rigidity were also observed. The EEG showed periodic synchronous discharge on July 25. The brain CT and MRI were normal. He became apallic gradually and died on October 28. The duration of illness was 5 months. At autopsy, brain weighed 1000gr. Cerebral atrophy and slight enlargement of the ventricles were observed. The cerebellum was also slightly atrophic. Histologically, the destruction of the cerebral cortical layer, slight sieve-like spongy state of the neuropil, slight neuronal loss of the thalamus and sieve-like spongy state of the striatum were observed. The cerebellar lesion was the most severe, where granular cell loss and gliosis of the cortex were observed.

The causes of symptomatic parkinsonism are enumerated and discussed including drug-induced, vascular, toxic, postencephalitic and posttraumatic parkinsonism. The environmental hypothesis and the concept of oxidative stress in the pathogenesis of Parkinson's disease are illustrated. The clinical diagnosis, the differential diagnosis and the possible diagnostic errors originating from the cardinal symptoms akinesia, rigor und tremor in the early stages of the disease are delineated. At last the contributions of EEG, CCT, evoked potentials, MRI, PET und the apomorphine test to the diagnosis especially early diagnosis are evaluated.

A 53-year-old woman developed symptoms of slow speech, mild dementia, increased deep tendon reflex, ataxic gait, flapping tremor, and dystonic posture during two years. She had liver cirrhosis and hyperammonemia, which suggested a diagnosis of portal-systemic encephalopathy. MR T1-weighted images showed increased signal intensity in globus pallidus, internal capsule, substantia innominata, and a part of hypothalamus. T2-weighted images revealed abnormal findings as follows: high intense area in middle cerebellar peduncle, and low signal intensity of corpus callosum and pontine base. This is the first report about MRI abnormalities in substantia innominata, corpus callosum, and pontine base in a patient with portal-systemic encephalopathy.

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)

The Gamma Knife is currently the only radiosurgical device which has been used in functional neurosurgery. This mode of utilization is possible because the instrument can make lesions in normal brains with a volume as small as 50 mm3. The experience of functional radiosurgery accumulated at the Karolinska Institute over 21 years is reviewed, and the possible implications of the new developments in imaging techniques for the future of functional radiosurgery are considered. The review covers gamma thalamotomy for pain and tremor, radiosurgery for trigeminal neuralgia, gamma capsulotomy for severe anxiety and obsessive-compulsive neurosis, and Gamma Knife surgery for focal epilepsy. The important role of stereotactic MRI localization in functional radiosurgery is pointed out, and a preliminary report of the recent experience with stereotactic magnetoencephalography combined with stereotactic MRI for physiological and anatomic target localization is given. It is concluded that functional radiosurgery should only be performed with radiation of very small volumes of brain, as the very high doses required would be devastating if delivered to even small volumes.
