Objective: Sensory symptoms are a prominent feature of variant Creutzfeldt-Jakob disease (vCJD), occurring at an early stage of the
illness. They are persistent and can be troublesome. Here, they are described in detail and a possible anatomical basis is
discussed.
Methods: The first 50 cases of vCJD confirmed by the National CJD Surveillance Unit (NCJDSU) were reviewed. Where possible the patients
and their relatives were interviewed and case notes were examined. The presence and nature of sensory symptoms and signs were
noted. Results of investigation and types of treatment offered were also reviewed.
Results: Of 50 definite cases, 64 % had persistent sensory symptoms, 16 % had no sensory symptoms and 18 % were uncertain. In 2 %
there was insufficient information. Of the 32 with definite symptoms, 31 % were symptomatic from the onset of the illness.
The symptoms were varied and some patients complained of more than one type of symptom. Limb pain was described in 63 % cases.
This was the most common symptom and was often non-specific and poorly localised, usually occurring in the lower limbs. Other
symptoms included cold feelings (25 % patients), dysaesthesia (28 % patients), paraesthesia (31 % patients) and numbness (25
% patients). The symptoms were lateralised in 31 % of patients.
Conclusions: Sensory symptoms are a prominent feature of vCJD, occurring in nearly two thirds of cases. They may help distinguish variant
from sporadic CJD. They are likely to be of thalamic origin but the recognised MRI changes in vCJD do not correlate with the
presence or absence of sensory symptoms. Neuropathological changes in the thalamus, however, show marked astrocytosis and
neuronal loss.

OBJECTIVE: Based on the current criteria, the diagnosis of "possible" or "probable" variant Creutzfeldt-Jakob disease (vCJD) implies the absence of periodic sharp wave complexes (PSWCs) in the electroencephalogram (EEG). To verify this point, we investigated the development of the EEG changes along the course of the disease in a pateint with vCJD. METHODS: Long-lasting EEG-polygraphic recordings were performed once a month during the last year of illness. RESULTS: We found the occurrence of a typical EEG periodic pattern in the late clinical stage of the vCJD patient. INTERPRETATION: In the light of our finding, the diagnostic criteria for vCJD should be amended to include the possibility of a typical periodic EEG in advanced stages of disease in cases with long survival. 相似文献

目的分析43例临床可能或很可能克雅氏病(CJD)患者的临床特征,为CJD早期诊断提供一些参考。方法搜集2013年1月至2016年1月以"可疑CJD"诊断在首都医科大学宣武医院住院的患者,对其临床特点及实验室资料进行分析。结果 CJD通常在60岁左右发病,平均病程5.70±5.08个月;首发症状多变,以迅速进展性痴呆为主。典型临床表现有6种:迅速进展的痴呆、运动系统损害(锥体束、锥体外系及小脑症状)、肌阵挛、无动性缄默、睡眠障碍和视力障碍。结论 CJD的早期诊断应重视其临床特征,当一个患者具有典型特征中的两项或以上表现时,即使14-3-3蛋白、脑电图(EEG)、磁共振(MRI)均不典型,也要高度警惕CJD,定期复查,以免漏诊。 相似文献

The authors describe the clinical features of Creutzfeldt-Jakob disease (CJD) with the causative point mutation at codon 180. The symptoms never started with visual or cerebellar involvement. The patients showed slower progression of the disease compared with sporadic CJD. They never showed periodic sharp and wave complexes in EEG. MRI demonstrated remarkable high-intensity areas with swelling in the cerebral cortex except for the medial occipital and cerebellar cortices. These characteristic MRI findings are an important clue for an accurate premortem diagnosis. 相似文献

BACKGROUND: The determination of the form of prion disease and early diagnosis are important for prognostic, public health, and epidemiologic reasons. OBJECTIVE: To describe a patient with sporadic Creutzfeldt-Jakob disease (sCJD) who had a clinical history and initial electroencephalogram and magnetic resonance imaging findings consistent with variant CJD (vCJD). RESULTS: Results of a repeated electroencephalogram were suggestive of sCJD, and a subsequent brain biopsy confirmed this diagnosis. CONCLUSIONS: This case cautions against relying solely on T2- and diffusion-weighted pulvinar hyperintensity and clinical features to differentiate between vCJD and sCJD, and further supports established diagnostic criteria for vCJD. 相似文献

Sporadic Creutzfeldt-Jakob disease (sCJD) is a rapidly progressive dementia (RPD) that can be difficult to identify antemortem, with definitive diagnosis requiring tissue confirmation. We describe the clinical, magnetic resonance imaging (MRI), cerebrospinal fluid (CSF), and electroencephalogram (EEG) measures of a small cohort of 30 patients evaluated for RPD. Clinical and diagnostic measures were cross-sectionally obtained from 17 sCJD patients (15 definite, two probable), 13 non-prion rapidly progressive dementia patients (npRPD), and 18 unimpaired controls. In a subset of patients (nine sCJD and nine npRPD) diffusion tensor imaging (DTI) measures [fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD)] were also obtained for the caudate, corpus callosum, posterior limb of the internal capsule, pulvinar, precuneus, and frontal lobe. Differences among groups were assessed by an analysis of variance. Compared to npRPD individuals, sCJD patients had cerebellar dysfunction, significantly higher CSF tau, “positive” CSF 14-3-3, and hyperintensities on diffusion-weighted imaging (DWI) that met previously established imaging criteria for sCJD. EEG changes were similar for the two groups. In addition, sCJD patients had significant decreases in DTI measures (MD, AD, RD but not FA) within the caudate and pulvinar compared to either npRPD patients or unimpaired controls. Our results confirm that CSF abnormalities and MRI (especially DWI) can assist in distinguishing sCJD patients from npRPD patients. Future longitudinal studies using multiple measures (including CSF and MRI) are needed for evaluating pathological changes seen in sCJD patients. 相似文献

There has been significant advance in our understanding of CJD and similar spongiform encephalopathies in recent years. The range in clinical expression of the disease is better appreciated, and the existence of "atypical" cases of CJD is increasingly recognized. New ideas about the possible modes of natural transmission have been derived from case-control studies in different parts of the world. 相似文献

Summary The neuropathological findings in 3 cases of Creutzfeldt-Jakob disease are described.The triad of morphological changes, i.e. neuronal loss, status spongiosus of the grey matter and proliferation and hypertrophy of fibrous astrocytes with or without microglial reaction, conforms to the typical pattern of pathology described in the literature. Degeneration of the cerebellum places these cases in the cortico-striato-cerebellar variant of the disease.The distribution of the lesions within cerebrum and cerebellum, with a more severe involvement of phylogenetically older portions, is unusual. In the cerebrum cortices belonging to the limbic system and the striatum were the most severely affected, whilst in the cerebellum the vermis and flocculo-nodular lobe bore the brunt of the pathological process. A similar distribution of the lesions is generally found in kuru.Further similarities with kuru are pointed out i.e. the occurrence of swollen, chromatolytic neurones predominantly within the infragranular layers of the cerebral cortex, of coarse intracytoplasmic vacuolation in many of the large striatal nerve cells and of kuru plaques within the cerebellum. Similarities and differences between the two diseases are discussed.
Zusammenfassung Die neuropathologischen Befunde von 3 Fällen von Creutzfeldt-Jakobscher Krankheit werden beschrieben.Die Trias der morphologischen Veränderungen — Nervenzelluntergang, Status spongiosus in der grauen Substanz, Proliferation und Hypertrophie faserbildender Astrocyten mit und ohne Mikrogliareaktion — entspricht dem typischen Muster der pathologischen Veränderungen in anderen Fällen der Literatur. Ihre Kleinhirnbeteiligung reiht die Fälle in die cortico-striato-cerebelläre Variante der Krankheit ein.Ungewöhnlich ist die Verteilung der Veränderungen im Großhirn und Kleinhirn mit der Bevorzugung phylogenetisch älterer Anteile. Am Großhirn waren die Rindenabschnitte des limbischen Systems und das Striatum am stärksten befallen; am Kleinhirn hat der pathologische Prozeß hauptsächlich den Vermis und Lobus flocculo-nodularis angegriffen. Eine ähnliche Anordnung der Veränderungen findet sich bei der Kuru-Krankheit.Weitere Ähnlichkeiten mit Kuru werden hervorgehoben, wie das Vorkommen von geschwollenen chromatolytischen Nervenzellen, besonders in den infragranulären Großhirnrindenschichten, von groben intracytoplasmatischen Vacuolen in vielen großen Striatumneuronen und von Kuru-Plaques im Kleinhirn. Ähnlichkeiten und Unterschiede der beiden Krankheitsbilder werden diskutiert.相似文献
