From early childhood, eight patients in a kindred had paroxysmal bouts of ataxia, dysarthria, and nystagmus. The disorder was inherited as an autosomal dominant. Attacks occurred weekly and lasted 1 to 6 hours; there were slight cerebellar signs between attacks. Although the etiology was not determined, a serendipitous trial of acetazolamide completely abolished attacks, and all patients have remained free of attacks for as long as 5 years.

A patient with symptomatic epilepsy receiving only phenytoin developed choreoathetosis and orofacial dyskinesias. These movement disorders disappeared when the drug was stopped and reappeared when the patient was challenged. Throughout the period of treatment, concentrations of phenytoin in serum were consistently low within the therapeutic range. Interfering symptoms from the cardiovascular system and the absence of some classic symptoms of phenytoin intoxication (nystagmus and dysarthria) contributed to delay the diagnosis. The patient died in hospital and autopsy of the brain showed rather localized encephalomalacies of corpus striatum. The pathogenic action of phenytoin and the role of preexisting brain lesions are discussed. Phenytoin must be suspected as the cause, when patients on this drug present with uncontrolllable epilepsy or neurological or mental deterioration.

The first autopsy of a case of multiple sclerosis from the District of Hokuriku was reported. The patient, a 50-year-old house-wife, born in Toyama Prefecture, had noticed a paresthesia of her face, fatigue, numbness and weakness in the right limbs, dimness of vision and gait disturbance at ave 44. Furthermore, in the course of the disease, she had suffered from visual disorder, tetraplegia, hyperreflexia, pyramidal signs and cerebellar syndroms such as dysarthria, nystagmus, intention tremor and ataxia. She also showed symptoms of euphoria and dementia. After a course of six years she died of bronchopneumonia. Remissions and exacerbations were noted four times during her clinical history. Histopathologically, there were many recent and old demyelinating lesions of varying sizes and shapes in all parts of the central nervous system, namely the cerebrum, brainstem, spinal cord and optic nerve. In contrast to the clinical symptoms, the cerebellum itself revealed less plaques than the other areas of the brain. According to the observed distributions of the lesions, our case can be classified as belonging to the optico-cerebro-spinal type in the Ikuta and Zimmerman classification. The demyelinated lesions were characterized by a perivenular distribution of the plaques, lack of tissue necrosis, paucity of inflammatory reaction and marked fibrous gliosis of varying degrees.

A 38-year-old man developed pain and peripheral-type weakness on the right side of his face and was discovered to have decreased hearing bilaterally, as well as optic nerve swelling on the right. The pain and optic nerve swelling subsided over a period of six weeks, but hearing loss and facial weakness persisted. Thirty months later, he developed dysphagia, ataxia, dysarthria, nystagmus, and progressive spastic quadriparesis. He died approximately four years after the onset of the illness. Although no evidence of disease was found other than in the central nervous system during life, two nodules in the right lower lung were found on autopsy. The examination of these nodules, as well as the brain stem, showed an angiocentric and angionecrotic process with lymphoreticular and plasmacytoid invasion.

A systematic search for cases of adult-onset hereditary ataxia was conducted on location in Scotland. The investigation resulted in the discovery of eight pedigrees with 42 patients of whom 16 were alive in 1975. Nine patients were examined by the authors and recent hospital records were available on the remaining seven. The clinical features were quite variable. In declining order of frequency, findings were gait and limb ataxia, dysarthria, hyperreflexia, extrapyramidal motor disturbances, impaired vibratory sense, spasticity, defects of extraocular movements and nystagmus, reflex depression, Babinski signs, impaired joint position sense, muscle weakness, optic atrophy, and mental abnormalities. Foot deformity occurred only once. Inheritance was compatible with autosomal dominant transmission, but complicated by consanguinity in two families. The minimum prevalence was calculated as 0.31/100,000. Autopsy in two members in one family revealed olivopontocerebellar degeneration.

A case of hypertensive intracerebellar hematoma surgically treated and cured was reported. The 41-year-old male had two cerebrovascular attacks with headache and vomiting followed by left hemiparesis. Drowsiness and dysarthria appeared the next day. The patient was admitted to a hospital, where right facial palsy, loss of right gag reflex and paralytic hemiplegia on the left side were noted. On the 7th day, the patient's consciousness became clear byt the other neurological evidences did not change. On the 14th day, bradycardia and central hyperventilation appeared and he became drowsy again. The patient was transferred to the authors' clinic. When the patient was admitted, he showed typical cerebellar signs such as nystagmus, ataxia, and slurring speech with pyramidal sign on left side and cranial nerves paralysis on right side, and also showed the changes of vital signs as a medullary syndrome in the late stage of the course. The vertebral angiogram revealed a space taking process in the right cerebellar hemisphere. The old blood (30g) was removed by suboccipital craniectomy. The hematoma cavity had a communication with the IVth ventricle through a small perforation in the medial wall of the hematoma. Spontaneour intracerebellar hematoma including of hypertensive origin is not rare in the reports of autopsy but surgically treated case has only rarely been reported. The main reason of few survivals should be in its fulminate course.

Autosomal dominant olivopontocerebellar degeneration was diagnosed in a family of Scottish ancestry by clinical examination and autopsy. In addition to having progressive cerebellar ataxia, head titubation, and severe dysarthria, the patients are unable to initiate saccadic eye movements. Slow pursuit movements are normal. Reflex movements of the eyes caused by passive rotation or caloric labyrinthine stimulation are not impaired but are not associated with nystagmus. The phenomenon can be classified as supranuclear pseudo-ophthalmoplegia. It differs from congenital ocular motor apraxia in age at onset and the absence of random eye movements. The anatomic lesion responsible for the defect of saccadic eye movements remains to be established.

Twelve members of a family with hereditary cerebellar ataxia of late onset were examined and, in 5, quantitative recording of eye movements were obtained. The initial and most severe symptom in all patients was ataxia of gait, followed by dysarthria and later by dysmetria of the limbs. Clinical examination did not reveal involvement of structures other than the cerebellum. Ocular motor examination showed: (1) inability to hold eccentric gaze resulting in gaze-paretic nystagmus; (2) downward beating nystagmus, accentuated on lateral gaze; (3) defective smooth pursuit, with relative preservation of optokinetic nystagmus induced by full-field stimulation; (4) rebound nystagmus; (5) enhanced gain (eye velocity/head velocity) of the vestibulo-ocular reflex during rotation in darkness; (6) decreased ability to suppress the vestibulo-ocular reflex during fixation of an object rotating with the patient; (7) saccadic dysmetria, especially downward overshoot; and (8) square wave-jerks. Although each of these signs can probably occur with lesions elsewhere in the brain, in combination they are highly suggestive of cerebellar involvement. With the reservation that we do not yet have pathological confirmation of the location of our patients' lesions, our results support the suggestion that the cerebellum specifically: (1) helps maintain eccentric gaze; (2) produces smooth pursuit eye movements; and (3) modulates the amplitude of saccadic eye movements. Many of the characteristics of the altered vestibulo-ocular responses and rebound nystagmus could be explained by the underlying anomaly in the smooth pursuit system.

The EEG response and drug kinetics after intravenous infusion of diazepam at 1-0 mg/min until nystagmus, dysarthria, and moderate sedation developed, has been investigated in five normal subjects and 17 patients with chronic liver disease. Diazepam induced adequate premedication with a similar clinical response in all subjects with no adverse reactions. Maximal response was during or within five minutes of infusion. The dose of diazepam required in liver chronic disease was 17-9 +/- 1-4 mg (M +/- SEM) compared with 27 +/- 5-4 mg in controls (p less than 0-01). Dose correlated significantly with serum albumin (p less than 0-05). Baseline mean dominant frequency (MDF) and slow wave index (SWI) significantly correlated with albumin (p less than 0-01). After diazepam, the MDF decreased and SWI increased. The change was greatest at the time of maximal clinical response. It was greater in liverdisease and was greatest in patients with previous hepaticencephalopathy. In spite of reduced dose requirements in liver disease, there was no significant difference in plasma concentration at the end of drug infusion...

An account is given of a form of hereditary, cerebellar ataxia and photomyoclonus. Eight cases from 5 generations were affected. The disease seemed to be transmitted as an autosomal dominant trait. The age at onset usually varied between 35 to 40 years. The symptoms and signs consisted of a cerebellar ataxia, dysarthria and intention tremor. There was no nystagmus. All patients exhibited photomyoclonus and were extremely sensitive to photic stimuli. Other signs were dementia, kyphosis, pes cavus and lipoma localized in the nape of the neck, shoulders and back. Two patients had a partial syndrome with photonyoclonus and skeletal deformities. None of the patients suffered from epilepsy, In one case, histopathological examination revealed atrophy within the cerebellar cortex, dentate nucleus and the posterior columns of the spinal cord. It is concluded that this syndrome belongs to a groups of hereditary ataxias and myoclonus, and differs from myoclonic cerebellar dyssynergia (Ramsay Hunt) and alos from a variety of familial myoclonus and ataxia (Gilbert et al. 1963);
