A 73-year-old man was admitted with gait disturbance and dysarthria. He showed right-side cerebellar ataxia. Computed tomography of brain showed left thalamic bleeding. Nine months later, he was admitted again because of seizure and consciousness disturbance. He had a history of diabetes mellitus and gout for five years, but no hypertension. On physical examination the lungs and heart were normal. On neurological examination, he showed stupor,pupils and eye position were normal. He showed right hemiparesis and urinary incontinence. The deep tendon reflexes were (+) at the upper limbs and (2+) at the right knee and ankle. Blood pressure was 162/88 mmHg and glucose was 275 mg/dl. Other laboratory data were normal. Brain CT showed hemorrhage of the left frontal lobe. The cystatin C level in cerebrospinal fluid was 68 ng/ml. Therefore we suspected cystatin C deposit amyloid angiopathy. In this case, thalamic hemorrhage was initially thought to be amyloid angiopathy. In cases of cerebral hemorrhage in the elderly without hypertension, we must be considered amyloid angiopathy.

A 55-year-old female with progressed dementia, cerebellar ataxia was reported. There was no family history of the same symptoms although her brothers, sisters and a son showed hypoceruloplasminemia and decrease of the serum copper content. On physical examination, anemia, dementia, dysarthria, torticollis, choreic involuntary movement of respiratory muscles, hyperreflexia in extremities and cerebellar ataxia were noted. Blood analysis revealed microcytic hypochromic anemia, diabetes mellitus, decrease of copper content of the serum and urine. Serum ferritin concentration was increased. Serum ceruloplasmin could not be detected. Biopsy of the liver showed that copper content in the liver was slightly increased and iron content was remarkably increased. On MRI study, dentate nucleus of the cerebellum, the thalamus, the putamen and the caudate nucleus and the liver showed low intensity in both T1 and T2 weighted images. Based on increased iron content in the liver, the radiological findings of the brain suggested deposition of iron in the brain. This deposition was considered as caused by deficiency of function of ceruloplasmin as ferroxidase. This disorder is suggested as a new disease due to ceruloplasmin deficiency different from Wilson's disease.

A 66-year-old female suffering from HTLV-1 associated myelopathy (HAM) for more than 30 years was hospitalized because of memorial impairment, deafness, dysarthria, dysphagia, and complete paraplegia. She first noticed stiffness and weakness of the right leg at 35 years of age. Gait disturbance was slowly progressed and complete paraplegia developed 18 years later. Neurological examinations on admission revealed that she was bedridden with decubitus, mental deterioration (pre-dementia of subcortical type), bilateral optic nerve atrophy, severe sensory-neural deafness, dysarthria, complete paraplegia, and marked neurogenic bladder. Laboratory data showed mild normocytic anemia and moderate diabetes mellitus. Anti-HTLV-1 antibody titers in serum and CSF were 78,192X and 1,024X, respectively (PA method). Serum levels of soluble IL-2 receptor was markedly elevated (2,200 U/ml). Peripheral blood lymphocytes showed spontaneous proliferation when cultured for 5 days (3H-thymidine uptake; 45,285 cpm/5 X 10(4) cells). MRI examinations of the spinal cord disclosed a predominant atrophy of lower thoracic cord without any compressive lesions. Brain MRI showed diffuse high intensity lesions of the periventricular area on T2 weighted images. Such abnormalities were predominantly found in fronto-parietal region and were quite similar to those of leuko-ariosis. Single photon emission CT using 123I-iodoamphetamine showed hypoperfusion of cerebral white matter on delayed image. It has been reported that intellectual impairment and brain atrophy are not usually seen in HAM patients. The present case, however, shows that such abnormalities of the central nervous system could occur in HAM patients with a long duration of illness.

Lacunar stroke was diagnosed in 337 (26%) of the 1,273 patients with cerebral infarction among the 1,805 total in the Stroke Data Bank. We analyzed the 316 patients with classic lacunar syndromes. Among these, 181 (57%) had pure motor hemiparesis, 63 (20%) sensorimotor syndrome, 33 (10%) ataxic hemiparesis, 21 (7%) pure sensory syndrome, and 18 (6%) dysarthria-clumsy hand syndrome. No striking differences were found among the risk factors for the lacunar subtypes, but differences were found between lacunar stroke as a group and other types of infarcts. Compared to 113 patients with large-vessel atherosclerotic infarction, those with lacunar stroke had fewer previous transient ischemic attacks and strokes. Compared to 246 with cardioembolic infarction, patients with lacunar stroke more frequently had hypertension and diabetes and less frequently had cardiac disease. We found a lesion in 35% of the lacunar stroke patients' computed tomograms, with most lesions located in the internal capsule and corona radiata. The mean infarct volume was greater in patients with pure motor hemiparesis or sensorimotor syndrome than in those with the other lacunar stroke subtypes. In patients with pure motor hemiparesis and infarcts in the posterior limb of the internal capsule, there was a correlation between lesion volume and hemiparesis severity except for the few whose infarct involved the lowest portion of the internal capsule; in these patients severe deficits occurred regardless of lesion volume. Taken together, the computed tomographic correlations with the syndromes of hemiparesis showed only slight support for the classical view of a homunculus in the internal capsule.

We describe four men from two kinships affected with X-linked recessive bulbospinal neuronopathy, and one sporadic case. All developed postural tremor, weakness, and fasciculations, with onset from age 25 to 39 years. Weakness began in the pelvic girdle or hands, with dysphagia or dysarthria occurring years later in two. Sensory symptoms were present in only one, who also had diabetes mellitus. In contrast, sural nerve action potentials were small or absent in all. Needle EMG showed widespread chronic partial denervation with reinnervation. The characteristic twitching of the chin produced by pursing of the lips consisted of repetitive or grouped motor unit discharges, rather than fasciculations. Broader awareness of the distinctive features of bulbospinal neuronopathy will probably increase the frequency of its recognition. Diagnosis is important for purposes of providing a prognosis for affected men and genetic counseling for affected families.

The clinical and genetic features of 80 patients with Friedreich's disease from 64 families are described. Diagnostic criteria were: no evidence of dominant inheritance, onset by the age of 20 years, progressive unremitting ataxia of limbs and gait, and absence of knee and ankle jerks. Furthermore, at least one of the following accessory signs was present: dysarthria, extensor plantar response and echocardiographic evidence of hypertrophic cardiomyopathy. Two peaks of onset age were evident at 6-9 and 12-15 years. Analysis of intra-family variation of onset age and absence of clustering of cardiomyopathy and diabetes did not suggest genetic heterogeneity. Peripheral nerve impairment was an early finding and showed slight further progression, whereas involvement of the cerebellar and corticospinal pathways appeared later and mainly accounted for the progressive worsening of the disease.

61 of 1,590 (3.8%) patients with cerebrovascular disease showed suprabulbar palsy of the pure form (42 patients; 2 had autopsy) and striate form (19 patients; 3 had autopsy). 25 patients with the pallidopyramidal syndrome were included since the clinical picture bordered on the striate form. The pure variety was characterized by dysarthria, dysphagia and automatic voluntary dissociation of facial movements. Half of the patients also had hemiparesis, primitive reflexes and short-step gait. In the striate form, the main signs were dysarthria, dysphagia, automatic voluntary dissociation, rigidity and hypokinesia. Brisk tendon reflexes, primitive reflexes, short-step gait and mental deterioration were also present in half of the patients. The pure variety was caused by multiple infarcts and/or lacunae (85.7%), while the striate form had vascular lesions by computed tomography in only 36.8% of the cases. Histological findings, showing lipohyalinosis of the arterial wall leading to stenosis and occlusion of the lumen and tissue rarefaction and disintegration, support the assumption that microinfarctions, sometimes found only by histopathological examination, are the leading pathogenetic factor in this form. Hypertension, cardiopathy, smoking habit, dyslipemia and diabetes are the most frequent risk factors in both forms.

We describe an analysis of 227 patients with lacunar infarcts; 177 were inpatients and the remaining 50 were outpatients. The group comprised 11% of all inpatients with cerebrovascular pathology and 16% of all consecutive inpatients with brain infarcts studied at the Department of Neurology of the Hospital de la Santa Creu i Sant Pau. The main risk factors identified in these patients were arterial hypertension in 164 (72%), diabetes mellitus in 64 (28%), and heart disease in 58 (26%). The most common clinical syndromes were pure motor hemiparesis in 125 (55%), pure hemisensory stroke in 42 (18%), the sensorimotor deficit syndrome in 34 (15%), ataxic hemiparesis in seven (3%), and the dysarthria-clumsy hand syndrome in four (2%); atypical syndromes were observed in 15 patients (7%). Lacunes were demonstrated by computed tomography in 100 patients (44%) and by magnetic resonance imaging in 35 (78%) of the 45 patients in which it was applied. Magnetic resonance imaging was significantly better (p less than 0.001) than computed tomography for imaging lacunes, especially those located in either the pons (p less than 0.005) or the internal capsule (p less than 0.001). After the acute phase, mild or no neurologic disability was detected in 178 patients (78.4%), moderate disability persisted in 48 patients (21.1%), and severe disability was recorded in one case (0.4%). Lacunar infarcts are a clearly defined entity with characteristic clinical features and an excellent short-term prognosis. Magnetic resonance imaging is the current method of choice for demonstrating these small brain lesions.

The authors report a clinical review of 16 childhood cases with early-onset cerebellar ataxia with retained tendon reflexes. The preservation of tendon reflexes distinguishes this disorder from Friedreich's ataxia. The mean age of onset of symptoms was 7.1 years. The main presenting symptom was abnormal gait (100%). Ataxia of gait and limbs and normal or increased tendon reflexes were found in all cases. This disorder is associated with dysarthria, pyramidal signs in the limbs, and in some instances, sensory loss. Other important differences from Friedreich's ataxia are absence of optic atrophy, diabetes mellitus, cardiomyopathy and severe skeletal deformity. Sensory nerve conduction was found to be normal, excluding one case. This finding constitutes another aspect of the syndrome different from Freidreich's ataxia. CT scans were normal in 2 of the 4 cases. The remaining two cases showed cerebellar atrophy. Inheritance is probably autosomal recessive in the majority of cases.

Fifty-three patients with infarction of the corona radiata adjacent to the body of the lateral ventricle were clinically evaluated in order to determine the clinical characteristics of this infarction and localization of the pyramidal tract in this area, as well as its somatotopy and etiology. Clinical characteristics included the following: (1) this type of infarction was observed in 9.1% of all patients with cerebral infarction; (2) although 81.1% of the patients of this type had clear consciousness and neuropsychological symptoms in some patients; (3) motor paralysis usually occurred in the upper limbs; (4) monoplegia occurred in 13.2% of patients, with monoplegia of upper and lower limbs being associated with infarction of the anterior and posterior portion, respectively, of the corona radiata adjacent to the body of the lateral ventricle; (5) pure motor hemiplegia was observed in 45.3% of patients; (6) facial paralysis and dysarthria were observed in 54.7% and 58.5% of patients, respectively, and the incidence of these symptoms was the highest in the infarction of the anterior portion of the corona radiata; (7) sensory disturbance, which was usually recognized as a mild subjective feeling of abnormality and localized to the limbs, was reported by 47.2% of patients; (8) risk factors included hypertension, diabetes and high hematocrit and triglyceride levels; (9) arteriosclerosis was often noted in areas between the siphon of the internal carotid artery and the main stem of the anterior and middle cerebral arteries; (10) 64.2% of patients were able to conduct independent activities of daily life (ADL) 1 month after the onset of the disease and more marked paralysis remained in the infarction of the middle portion than in the anterior or posterior portion.(ABSTRACT TRUNCATED AT 250 WORDS)
