Motor disorders reported in the present paper do not result from cortical ablations stricto sensu since some white matter was excised in every patient. However they appear to suggest that, as suggested by Walshe (1935), the central region and premotor area are a functional entity, i.e. they work as a whole. The extensive lesions of the premotor area, leaving untouched the motor region, have the same motor and tonic consequences as lesions limited to the central region. This point which appears specific for man does not imply that the premotor region subserves activities similar to those subserved by the central region. Rather it may suggest a deafferentiation of the central region, the consequences of which would be more important than is generally assumed. Extensive central or premotor lesions determine various tonic disorders: a well known spasticity, with exaggeration of the stretch reflex, associated with an increase in passive swinging of segments of limbs and in extensibility of joints. These two latter phenomena are usually defined as hypotonia. With premotor and precentral lesions the hypotonia disappears and a hemiplegic posture is observed. This hemiplegic posture is a dystonia which apparently does not result directly from the exaggeration of the stretch reflex. Anatomically it appears to result from lesions of both central and premotor regions. This is in agreement with Denny-Brown's (1966) contention that an extrapyramidal region lies rostral to the prerolandic sulcus. As suggested by Evarts (1973) motor regions appear to control automatic as well as voluntary movements. They probably play a role in the trophic function of muscle, since, despite rehabilitation, amyotrophy was present in every case reported in the present paper.

The author reviews information on the use of a pulsatile magnetic field with defined parameters in some child diseases of the CNS according to his experience assembled during the past five years. PMP was applied in 17 cases with spinal amyotrophy type M. Werdnig-Hoffman and in 16 cases with DMO. In both diseases treatment was previously only symptomatic. PMP frequencies of alpha EEG waves were used during application on the area of the head and a different frequency for whole body treatment focused on muscular dystonia. The author draws attention to the specificity of biotropic parameters of the applied magnetic field.

Four pedigrees of Machado-Joseph disease (MJD) were reported. Main clinical features of 21 patients in these pedigrees were cerebellar ataxia, limb spasticity, gaze nystagmus, facio-lingual twitchings, and external ophthalmoparesis. Amyotrophy, hypokinesia, or dystonia were manifested with advance of the illness. In patients with younger onset age, such extrapyramidal signs were dominated. Neuropathological study of one autopsied case disclosed that there were degeneration of spinocerebellar tract, anterior horn cells, pontine nuclei, dentate nucleus, red nucleus, substantia nigra, internal segment of globus pallidus, subthalamic nucleus, and motor nuclei of brain stem; neurons of cerebellar cortex and inferior olivary nucleus were preserved. From these clinical and pathological features, these 4 pedigrees satisfied the criteria of MJD, and were differentiated from hereditary olivopontocerebellar atrophy. Currently, MJD is accepted as a new entity of hereditary spinocerebellar ataxias. However, there are still controversies as to whether Azores-Portuguese MJD and Japanese MJD are identical disorder. Furthermore, the nosological relationship between MJD and a number of similar cases, as reported historically under the diagnosis of Brown type ataxia or Marie's ataxia, has not been clearly established. From reviewing such cases critically, pathological and clinical features of our cases are so similar to those of the latter, indicating that the probably identical genetic disorder has been classified under the different categories.

One male and two female cases in a family of Machado-Joseph disease were reported. Two cases showed typical symptoms that are characterized by bulging eyes, ophthalmoplegia, dystonia, ataxia, spasticity of extremities and amyotrophy, and were consistent with Type II (Rosenberg et al). But another one lacked diversity of the symptoms, showing mainly progressive cerebellar ataxia for over 10 years. We pointed out the existence of a new type of MJD case exhibiting only progressive cerebellar ataxia over a long period. A female patient had dyspnea and insomnia after 20 years in her clinical course, and central sleep apnea was revealed by respiratory monitor. But, the apnea and irregular respiration appeared in both awake and sleep stages. We described the importance of attention to the apnea as a new complication of Machado-Joseph disease.

We evaluated magnetic resonance image (MRI) in 21 cases of hereditary spinocerebellar degenerations (SCD) of autosomal dominant trait. By the discriminant formula based on size of the cerebellar vermis and ventral pons, which was reported in our previous study, the patients were classified into three types. Group 1 included the cases with atrophies in the vermis and pons; OPCA type. Group 2 showed vermian atrophy and less significant atrophy in pons; LCCA type. And Group 3 was no significant atrophies both in vermis and pons. Cases in Group 1 were furthermore divided into two groups according to width of the midbrain tegmentum. Group 1A, with normal midbrain tegmentum, was consisted of five cases. Four cases were diagnosed as Menzel type OPCA. Another case showed various clinical symptoms and relatively mild atrophies for his duration of illness. His family members were classified to Group 3. Seven cases in Group 1B showed reduced midbrain tegmentum. Four cases showed ataxia, spasticity, ocular symptoms, bladder dysfunction and amyotrophy with or without fasciculation, and they seemed to be a special type of SCD mimicking Joseph disease. One case showed bulging eyes, ocular movement palsy and dystonia. However, his sister manifested only ataxia with very mild ocular movement disorder. Their MRI demonstrated severe atrophies in the cerebellum, pons and afferent cerebellar peduncli, and this pedigree was thought to be Menzel type OPCA with various associated disorders. Another case was clinically diagnosed as dentate-rubro-pallido-luysian atrophy. Group 2 was consisted of 6 cases who were clinically diagnosed as Holmes type LCCA. MRI demonstrated medial dominant cerebellar atrophy.(ABSTRACT TRUNCATED AT 250 WORDS)

The propositus (case 1) was a 40 year-old man. He had begun to note unsteady walking at age 26. He was found to have cerebellar ataxia and pyramidal signs in addition to minor features such as progressive external ophthalmoplegia, gaze nystagmus, bulging eyes, intention fasciculation-like movements of facial and lingual muscles, and limb dystonia. These findings were categorized into type II form of the disease. One sister (case 3) aged 37 years, and one brother (case 4) aged 44 years of the propositus had also type II form of the disease. His uncle (case 2) had the same cerebellar and extrapyramidal signs accompanied with peripheral nerve signs such as muscle wasting, weakness, hypo-tonus and decreased deep tendon reflexes, and a diagnosis of type III form of the disease was made. In the T2-weighted magnetic resonance imaging (1.5 T, TR 2000 or 3000 msec, TE 120 msec) of the three patients (case 1, 3 and 4), dorsolateral part of the putamen showed decreased signal intensity. Although hypo-intensity of the putamen is often observed in normal elderly people over 50 years old, it is considered to be abnormal when it exists in relatively young people as in this family members.

The patient, a 31-year-old married woman, noticed spasticity on walking at the age of 19 accompanied by ataxia, dysarthria and dysphagia. Facial twitching and dystonic movement of extremities have been observed since age 27. A sister of her father showed the similar ataxia and dysarthria, and expired of pneumonia at the age of 45. On admission at the age of 29, neurological examinations revealed nystagmus, marked spasticity with pathological reflexes and clonus, cerebellar ataxia, dysarthria and dysphagia, diffuse muscle wasting, fasciculation in facial musculature, and generalized slow dystonic movement. By neuro-otological studies bilateral MLF syndrome with upward gaze limitation and decreased velocity of saccadic eye movement were detected. Surface EMG at rest showed a dystonic discharges on the extremities. Needle EMG disclosed a systemic neurogenic change with reduced interference and high amplitude potentials. Atrophy of the brainstem was remarkable on the cranial CT and MRI. These abnormal eye movements, especially bilateral MLF syndrome and generalized dystonia seem to be quite unusual in the variety of spinocerebellar degenerations. On reviewing detected clinical descriptions on Joseph disease this case can be probably included.

A 24-year-old man presented with dystonia, dementia, amyotrophy, choreoathetosis, and ataxia. Partial hexosaminidase A deficiency was documented in serum and leukocytes and confirmed by rectal biopsy with ganglion cells containing membranous cytoplasmic bodies. A brief review of the literature reveals that tremor, dystonia and choreoathetosis are common but neglected symptoms associated with chronic GM2 gangliosidosis.

Joseph's disease is a hereditary ataxia found among descendants of Portuguese from the Azores Islands. We describe the clinical and pathological features of 4 members of a Japanese family who were diagnosed as having Joseph's disease. The illness began with cerebellar ataxia between the ages of 18 and 45 years. Nystagmus, dysarthria, and pyramidal signs were early manifestations. External ophthalmoplegia, dystonia and/or athetotic movements, and muscular atrophy appeared in the late stages. Neuropathological findings in one patient revealed degeneration of the dentatorubral and pallidoluysian systems, substantia nigra, pontocerebellar system, Clarke's column and spinocerebellar tracts, and anterior horn cells, as well as the cranial nuclei in the brainstem. Neurons in the inferior olivary nuclei, Purkinje's and granule cells, the cerebral cortex, thalamus, and striatum were spared. Involvement of the dentatorubral and pallidoluysian systems seems to be a characteristic feature of this disease in Japan.

A Portuguese family of non-Azorean origin is described as affected by an autosomal dominant inherited ataxia resembling Machado-Joseph disease. Clinical criteria for diagnosis are proposed, based on a complex clinical picture extending from extrapyramidal signs to peripheral amyotrophy associated with secondary, but more specific, minor features such as progressive external ophthalmoplegia, dystonia, intention fasciculation-like movements of facial and lingual muscles, and bulging eyes. Machado-Joseph disease may be more widespread than previously believed.
