The clinical and pathological features of 35 cases with multiple system atrophy collected in the United Kingdom Parkinson's Disease Society Brain Bank (UKPDSBB) between 1985 and 1992 have been analysed. The median age of onset was 55 (range 33.3-75.8) years and median survival was 7.3 (range 2.1-11.5) years. Parkinsonism, usually asymmetric, occurred in all, and autonomic failure in all but one case. Cerebellar signs were noted in 34% and pyramidal features in 54% of the cases. Glial cytoplasmic inclusions were found in all cases with adequate fixation. Lewy bodies were detected in three cases. The substantia nigra was (usually severely) depleted of cells in all cases. With two exceptions the putamen was atrophic; the caudate and pallidum were less commonly and less severely affected. Overall nigrostriatal cell loss correlated with severity of disease at the time of death. The latest, but not the best, recorded levodopa response tended to be inversely related to the degree of putaminal degeneration. The olivopontocerebellar system was involved in 88% of the cases, the cerebellar vermis usually being more severely affected than the hemispheres. The presence of associated cerebellar pathology was, however, unrelated to the presence of cerebellar signs in life. 相似文献

We investigated cerebral atrophy in multiple system atrophy (MSA) by quantitative analysis of MRI. The subjects were 28 patients with MSA (14 striato-nigral degeneration; SND, 14 olivo-ponto-cerebellar atrophy; OPCA. 106 MRI examinations were performed totally) and 85 normal persons for control. The ratios of the ventral pons to the infratentorial space in the sagittal section, the putamen, cerebrum, frontal lobe and parietal & occipital lobes to the intracranial space in the horizontal section, and the temporal lobe to the intracranial space in the coronal section were measured. In the early stage of the disease, OPCA showed significant atrophy of the ventral pons compared with SND, and conversely, SND demonstrated significantly smaller putamen than that in OPCA. According to the progression of the disease, the atrophy of these neural tissues progressed, which resulted in no significant differences between SND and OPCA. The cerebral atrophy was observed in 17 MSA patients. The atrophy of the frontal lobe was much frequent and prominent to that in the temporal lobe and parietal & occipital lobes. SND showed higher incidence of the cerebral atrophy than OPCA in the early stage of the disease. In long period follow-up cases, one case showed cerebral atrophy in earlier stage, and another case in late stage. We indicated the involvement of the cerebral hemispheres in MSA, especially the frontal lobe. 相似文献

This study aimed to determine in vivo the atrophy patterns in clinically established cerebellar variant of multiple-system atrophy (MSA-C) using voxel-based morphometry (VBM). Thirteen patients with MSA-C (12 probable, 1 possible) and 13 healthy controls matched for age and sex were included. High-resolution MR images were acquired with a 1.5 T scanner. Images were normalized onto a study-specific template, segmented into the tissue compartments, modulated with the Jacobian determinants, and finally smoothed with a Gaussian kernel filter of 10 mm. The general linear model was used to assess statistical differences in gray and white matter. Infratentorial atrophy was observed in the cerebellar hemispheres, vermis, mesencephalon, and pons of MSA-C patients. Supratentorial volume loss was found in orbitofrontal and mid-frontal regions as well as in temporomesial and insular areas of both hemispheres. A negative correlation was observed between a cerebellar ataxia score and the volume of cerebellar hemispheres, peduncles, and pons. To compare this atrophy pattern to that of spinocerebellar ataxia (SCA2), which was previously reported by our group, a conjunction analysis was assessed. We observed a volume loss shared by both disorders comprising the cerebellum, vermis, pons, mesencephalon, orbitofrontal, mid-frontal, and temporomesial cortex of both hemispheres as well as the left insular cortex. 相似文献

Olfactory dysfunction is a characteristic clinical sign in Parkinson's disease (PD); it is also present in multiple system atrophy (MSA). The pathological basis of hyposmia or anosmia in PD is well known: the olfactory bulb (OB) contains numerous Lewy bodies and severe neuronal loss is present in the anterior olfactory nucleus (AON). We established that glial cytoplasmic inclusions (GCIs) are present in all the OBs from MSA cases. Their presence in the OB is diagnostic for MSA. Additionally, neuronal loss is present in the AON in MSA. These pathological changes might be responsible for the olfactory dysfunction seen in MSA. 相似文献

Ehlers-Danlos Syndrome is a rare group of inheritable disorders resulting in abnormal collagen production, leading to skin fragility, joint hypermobility and easy bruising. Six major subtypes have been identified, of which Type IV most often leads to neurovascular complications, may lead to inner organ rupture and overall has the worst prognosis. Early recognition followed by genetic testing is key, since this diagnosis will guide decision making in the management of complications, influence the choice of antiplatelet medications versus anticoagulants and allow for potentially affected family members to be identified, undergo genetic testing and reproductive counseling. We here report the case of a 50 year old woman with a fulminant presentation of Ehlers Danlos Syndrome Type IV, including bilateral carotid and vertebral artery dissection, multiple strokes and liver rupture. Of note, this patient did not have a known history or obvious clinical features of connective tissue disease. Genetic testing confirmed the diagnosis. Review of her family history revealed multiple family members with a history of aortic dissection or aneurysm rupture. This case illustrates that Ehlers Danlos Syndrome Type IV is an important differential diagnosis even in adult patients without a known history of connective tissue disease and no prior complications. 相似文献

Nine patients with multiple system atrophy (MSA) were studied based on MRI findings of cerebral hemispheric involvement. The age at onset was 56.4+/-8.6 (mean+/-S.D.) years, duration of illness at the first MRI study 2.1+/-1.1 years, duration of illness at the last study 9.7+/-2.6 years, and the follow-up duration 7.6+/-2.3 years. Controls were 85 neurologically intact persons (60.2+/-11.1 years age). In the MRI study, measurements of the ratio of each area to the intracranial area were performed for the cerebral hemisphere, frontal, temporal and parietal-occipital lobes. A significant progression of atrophy to under the normal limit was observed in the cerebrum, frontal and temporal lobes. Besides the typical pathological lesions in MSA, five autopsied patients revealed frontal lobe atrophy with mild gliosis, mild demyelination and glial cytoplasmic inclusions (GCIs). One of these patients showed remarkable frontal lobe atrophy with degenerative changes in the cerebral cortex. We observed the involvement of the cerebral hemisphere, especially the frontal lobe. 相似文献

In this study, we aimed to determine the progression of brain atrophy in the parkinson variant of multiple system atrophy (MSA-P). Voxel-based morphometry was applied to two consecutive high resolution MR images of 14 patients with probable MSA-P in comparison to 14 patients with Parkinson's disease (PD). The time interval between baseline and follow-up investigations (1.0 +/- 0.5 SD years in MSAP and 1.4 +/- 0.6 SD years in PD patients) was introduced as covariate in the statistical analysis. Additionally, correlation analyses were performed between the progression maps and clinical data. We observed marked progression of brain atrophy in the MSA-P cohort, the regions including striatum, mesencephalon, thalamus and cerebellum, but also cortical regions such as the primary sensorimotor cortex, supplementary motor area, lateral premotor cortex, medial frontal gyrus, middle frontal gyrus, orbito-frontal cortex,insula, posterior parietal cortex and hippocampus. Short disease duration was correlated with progression of atrophy in the striatum whereas longer disease duration was correlated with increasing atrophy in the cortical areas and cerebellar hemispheres. The UPDRS-III score was not significantly correlated with any brain region. Our data suggest that cortical atrophy is prominent in MSA-P and early degeneration of the basal ganglia drives late onset cortical atrophy. 相似文献

Multiple system atrophy (MSA) is a form of atypical parkinsonism with unknown etiology. The epidemiological studies conducted up to now on this disease are scarce. The incidence rate is about 0.6 cases per 100 000 persons per year. The prevalence rates show 4–5 cases per 100 000 persons. In Italy, about 4900 prevalent cases have been estimated. The mean onset age is about 54 years; the median survival is 7–9 years. Only one case-control study has been performed on this disease. This study showed an increased risk MSA associated with occupational exposure to organic solvents, plastic monomers and additives, pesticides and metals. Smoking habits seem to be less frequent in MSA cases (as in Parkinson's disease cases) than in healthy controls. Quinn's clinical criteria and those of the Consensus Conference promoted by the American Academy of Neurology are in fair agreement. We have performed a case-control study on 73 MSA cases, 146 hospital controls and 73 population controls. 相似文献

Multiple system atrophy represents an enigmatic, clinico-pathologically defined neurodegenerative disease. According to findings of the last three decades, the historically derived, previously used terms olivopontocerebellar atrophy, striatonigral degeneration, and Shy-Drager-syndrome should be avoided in clinical use because of both the clinical and morphological overlap between these syndromes. Complex neurodegenerative syndromes other than multiple system atrophy according to recently developed criteria, should rather be referred to as multiple system degenerations. 相似文献

Fifteen of 23 pathologically confirmed cases of multiple system atrophy (MSA) showed some initial response to levodopa and eight of these remained at least partially responsive at the time of death. Eleven developed motor oscillations, and drug-induced dyskinesias, often involving the face and jaw, were also seen in 11 cases. Acute levodopa and apomorphine challenges were administered to 11 patients with clinical MSA who were considered levodopa responsive. A short duration relatively small amplitude response with associated dyskinesias occurred in six and a further three developed dyskinesias without any motor response. Following levodopa withdrawal, a delayed deterioration occurred after three to six days in six patients, five of whom had shown no short duration motor response to the acute challenges. The occurrence of levodopa-induced dyskinesias without a concomitant motor response and delayed deterioration several days after levodopa withdrawal may be more typical of patients with MSA than Parkinson's disease. 相似文献

Stridor and death in multiple system atrophy. 总被引：3，自引：0，他引：3
Patients with multiple system atrophy (MSA) have a mean survival of 8 to 10 years. Nocturnal stridor has been considered a poor prognostic feature. We analyzed demographic, clinical, and polysomnographic data and obtained follow-up information from 42 patients with MSA (30 with follow-up data) seen in a Sleep Disorders Center. Group I consisted of 17 patients with nocturnal stridor, including seven with daytime stridor. Group II consisted of 25 patients without stridor. Analysis of survival curves of 30 patients with follow-up information showed a significantly shorter survival from the sleep evaluation, but not from disease onset, for patients with stridor compared with those without. Nine of 11 patients with stridor died a median of 2 years from presentation and the only two survivors had undergone tracheostomy. Patients with daytime stridor and immobile vocal cords had especially poor prognoses. However, two of four patients with tracheostomies also died, as did six of 19 without stridor. We postulate that central hypoventilation and its complications may have been responsible for many of these other deaths. We conclude that stridor does carry a poor prognosis in patients with MSA but that there are also other causes of death. We recommend consideration of tracheostomy for patients with MSA who have stridor, but also assessment for central hypoventilation and appropriate management if it is present. 相似文献

Cranial magnetic resonance images (MRI) of the cerebral areas of 40 patients with multiple system atrophy (MSA) and of 61 age-matched controls were analyzed. The cerebral area of MSA patients was 131. 95+/-15.89 cm(2) (mean+/-S.D.), which was significantly smaller than that of normal controls at 149.01+/-10.93 cm(2) (P<0.0001). All 23 MSA cases subjected to the MRI study over a 1-year period showed progressive cerebral atrophy, and the atrophy rate was 2.46+/-1. 66%/year. There were no significant differences within the MSA subtypes or between gender. The progression of cerebral atrophy in MSA correlated more with duration (r=-0.634) than age (r=-0.421). We conclude that MRI findings throughout the course of MSA suggest progressive cerebral atrophy, which is common in all subtypes and reflects duration of the disease rather than age. 相似文献

Pain is a recognized feature of idiopathic Parkinson’s disease (IPD) but has never been studied in multiple system atrophy
(MSA), the commonest cause of atypical parkinsonism. We retrospectively analysed histories of pain in 100 consecutive cases
of clinically probable MSA. Details were obtained from the medical records of 100 patients with MSA, comprising 82 with the
striatonigral degeneration (SND) type and 18 with the olivopontocerebellar atrophy (OPCA) type of MSA. Pain was reported in
47% of the MSA patients. It was classified as rheumatic in 64% of MSA patients reporting pain, sensory in 28%, dystonic in
21%, and levodopa-related in 16%, mostly related to off-period or diphasic dystonias. There was a mixed pain syndrome in 19%
of these patients. Pain was significantly more commonly reported by females (P=0.02), and by patients with levodopa-induced dyskinesias (P=0.02). No other clinical feature differentiated MSA patients who reported pain from those who did not. The mean delay between
disease onset and onset of pain was 2.9 years, but pain was reported at the time of, or before, disease onset in about 30%
of patients. The overall prevalence of pain in MSA was similar to that reported in IPD, but the distribution of pain categories
was different. 相似文献

We investigated the family histories of 157 Japanese patients with probable or possible multiple system atrophy (MSA). A family history of neurodegenerative disorders was only detected in three MSA patients (1.9%). We evaluated these patients by careful neurological examination, neuroimaging studies, and genetic studies to exclude hereditary spinocerebellar ataxia with a similar clinical phenotype to MSA. The results indicated that one of them had a family history of MSA. Although the familial presence of neurodegenerative disorders is rare in MSA patients, the existence of such cases suggests that MSA may have a genetic background. 相似文献
