Clinical symptoms and regional cerebral blood flow in schizophrenia   总被引:6,自引:0,他引:6  
This study examined the relationship between clinical symptoms and regional cerebral blood flow (rCBF) in schizophrenic patients using single photon emission computed tomography (SPECT). The subjects were 26 medicated schizophrenic patients diagnosed according to DSM-III-R criteria. Clinical symptoms were assessed using the Scale for the Assessment of Negative Symptoms (SANS), selected items for the Positive and Negative Syndrome Scale (PANSS), and the scale for Schneider's first rank symptoms. Resting rCBF was measured using N-isopropyl-p-[I-123] iodoamphetamine (I-123 IMP) SPECT, and relative rCBF distribution was evaluated in nine regions of interest in each hemisphere. Factor analysis of symptom ratings indicated four separate syndromes: psychomotor poverty, alienation (hallucination and disturbance of the self), delusion, and disorganization. Stepwise multiple regression analysis showed the psychomotor poverty syndrome to be correlated with decreased rCBF in bilateral superior frontal areas and increased rCBF in the left thalamus and right basal ganglia. The disorganization syndrome was correlated with increases rCBF in bilateral anterior cingulates and decreased rCBF in bilateral midolle frontal areas. The alienation syndrome was shown related to increased rCBF in the right inferior frontal area and parietal area. Dysfunction in distinctive neural networks involving various prefrontal areas would thus appear to underlie these syndromes in schizophrenia.  相似文献

Abstract: A total of 202 nonepileptic patients (120 males and 82 females) who exhibited spike abnormalities at least twice in their EEG examinations were studied. The incidence of spike abnormalities among nonepileptic patients was 8.1% (847/10,473). The majority (90%) were under age 19. Headache, dizziness and vomiting, and abdominal pain were more frequently observed compared with controls. Mild paroxysmal EEG abnormalities such as diffuse irregular slow wave bursts with spike (27%), positive spikes (25%) or small spike (8.4%) were commonly detected.
In three patients who developed epileptic seizures during the follow-up period, more specific EEG abnormalities were often exhibited. Other factors like the age at onset before 9, characteristic clinical symptoms or a positive family history of seizures were confirmed to be necessary for the manifestation of clinical seizures.  相似文献

不同时期麻痹性痴呆临床对照研究   总被引:3,自引:0,他引:3  
目的:分析1947年至1966年和2004年至2007年丽个不同历史时期麻痹性痴呆(GPI)患者的临床差异。方法:回顾性调查1947年6月至2007年6月GPI住院患者临床情况。病例分旧患者组(1947年至1966年时期247例中随机抽取50例),和新患者组(2004年至2007年期间,计12例)两组,进行对照分析。结果:旧患者组收治12.4例/年,新患者组3.42例/年;入院前和入院3d内作血液和脑脊液梅毒抗体检测旧患者组96%,新患者组为0%;临床误诊率旧患者组4%,新患者组100%;两组差异有显著性(P〈0.01)。结论:目前GPI临床少见,患者性病冶游史隐蔽,临床血清梅毒的筛查未列为常规性检查,容易导致误诊。  相似文献

Prevalence of stroke in a district of Copenhagen   总被引:2,自引:0,他引:2  
From the city center of Copenhagen, almost 20,000 people, 20 years of age and older, were randomly selected for examination after age and sex stratification. The participation rate was 72%. 231 persons responded affirmatively to a questionnaire concerning cerebrovascular disease. After neurological examination the diagnosis was confirmed in 115 cases. Adjusted on the basis of the age distribution of the Danish population (1976) the prevalence rate was calculated to be 651/100,000 for men and 385/100,000 for women.
The frequency of myocardial infarction and hypertension was significantly higher in the stroke patients than in the study population. The risk factors: cigarette smoking, serum-cholesterol, and high-density-lipoprotein concentration, showed no significant differences between the patients and the study population. 44% of the patients had had their stroke more than 5 years before the prevalence date. In 41% of the patients, residual neurological signs could not be demonstrated, while 59% of the patients had neurological deficits of varying severity. 30% of the surviving patients were in gainful work or managed domestic activities as they had done before the stroke. Nearly 1/2 of the severely disabled patients were independent in self care. The age group above 80 years was underrepresented in this study.  相似文献

自发性脊髓硬膜外血肿的临床特征   总被引:2,自引:0,他引:2  
目的对自发性脊髓硬膜外血肿的临床表现、影像学特点和病因进行总结。方法回顾4例经MRI证实的脊髓硬膜外血肿患者的资料,其中2例进行了脊髓硬膜外血肿清除术和病理学检查。结果4例患者均为急性起病,伴明显的胸背部疼痛,截瘫和尿潴留等脊髓受压的症状和体征。腰穿脑脊液检查结果正常。急性期MRI检查均可见受压节段脊髓硬膜外呈条形或梭形异常信号影,T1W等信号。T2W稍高信号,高信号中间杂小斑片状低信号。病理学结果为1例肉芽肿合并血肿。1例血管畸形合并血肿。2例外科手术的患者术后神经功能迅速恢复。2周后出院。未手术患者3-4周后出院。结论胸背部剧烈疼痛、单侧和双下肢截瘫、尿便障碍、影像学改变是诊断自发性脊髓硬膜外血肿的主要依据。脑脊液正常对诊断常有帮助。手术治疗可缩短病程和减少复发。也是病因检查的最有效方法。  相似文献

目的 结合视神经脊髓炎(NMO)与多发性硬化(MS)患者的临床症状和脊髓MRI特点探讨两者之间差异发生的机制.方法 回顾性分析中山大学附属第三医院自2004年1月至2007年1月收治的23例NMO患者及21例MS患者的临床资料,比较其临床症状及脊髓MRI上受损部位MRI上的差异.结果 NMO患者多为女性,且首次发病年龄、扩展病残状况评分(EDSS)评分均高于MS患者;双侧深感觉障碍、束带感、直肠或膀胱括约肌功能障碍3种临床症状在NMO、MS患者中的发生率不同,差异均有统计学意义(P<0.05);上述各临床症状基本能在脊髓MRI找到相应受损病灶.结论 NMO是不同于MS的脱髓鞘疾病,其特殊的发病机制导致其临床症状与脊髓MRI均有自己的特点.  相似文献
