目的探讨急性脑卒中后焦虑抑郁共病患者血清单胺类递质水平的关系。方法采用荧光分光光度计法测定33例急性卒中后焦虑抑郁共病患者、22例急性卒中后抑郁患者、49例卒中后非焦虑抑郁患者及37例正常人血清单胺类递质的水平。结果急性脑卒中后焦虑抑郁共病组和PSD组血清中,NE、5-HT、DA含量低于非焦虑抑郁组和对照组,共病组NE、5-HT高于抑郁组,其中5-HT差异有显著意义,而非焦虑抑郁组血清中,单胺类递质的含量亦低于对照组。而大脑左侧及前部卒中患者的血清中单胺类递质水平低于其它卒中部位患者(P〈0.05)。结论急性脑卒中后焦虑抑郁共病组和单纯PSD的发生与血清中单胺类神经递质的降低有关。  相似文献

ObjectiveSleep disturbance and depression are common in stroke patients, however, little is known about the role of sleep in post-stroke depression. This study examined the association between pre-stroke sleep duration and depression at 90 days post-stroke in a population-based bi-ethnic sample.MethodsThe study included 1369 stroke patients from the Brain Attack Surveillance in Corpus Christi project who survived 90 days post-stroke. Depression at 90 days post-stroke was assessed by the 8-item Patient Health Questionnaire, and pre-stroke sleep duration was self-reported shortly after stroke in reference to the pre-stroke state. Multiple imputation and inverse probability weighting were used to deal with missing data and attrition. Weighted logistic regression models were fit to examine the association between pre-stroke sleep duration and post-stroke depression.ResultsThe mean age was 68.2 years, and 63.6% were Mexican American. The prevalence of post-stroke depression was highest among participants reporting less than 6 hours of sleep before stroke (52.4%, 95% confidence interval = 45.7%–59.0%). Compared with participants reporting 7–8 hours of sleep before stroke, those with short sleep duration had significantly increased odds for post-stroke depression (odds ratio = 1.96; 95% confidence interval = 1.38–2.79), after adjustment for sociodemographic, stroke and pre-stroke characteristics including pre-stroke depression.ConclusionsPre-stroke short sleep duration may be an independent risk factor for post-stroke depression.  相似文献

目的:探讨脑卒中后抑郁状态患者的睡眠图异常改变及与抑郁症之间的差异。方法:采用多导睡眠图对62例脑卒中和30例抑郁症患者进行整夜睡眠描记,并与对照组比较。结果:卒中后抑郁组与对照组和非抑郁组比较多项睡眠指标均有显著性差异(P<0.05~0.01);卒中后抑郁组的REM睡眠时间和密度明显低于抑郁症组,差异有显著性(P<0.01)。结论:卒中后抑郁状态病人除具有睡眠障碍在多导睡眠图改变外,REM睡眠时间和密度是一个较为特征性的改变,卒中后抑郁状态的发生可能与脑内5-TH递质改变有关。  相似文献

Aims: To investigate the correlation between the incidence of post‐stroke depression (PSD) and the levels of substance P (SP) in the plasma and cerebrospinal fluid (CSF). Methods: Ninety‐one stroke patients were divided into PSD (n = 46) and post‐stroke (without depression) groups (n = 45). PSD must have occurred 2–4 weeks after the onset of the stroke and was determined by the Hamilton Rating Scale for Depression (HAMD). In addition, the subjects were divided into anterior (n = 67) and posterior circulation stroke groups (n = 24) based on the location of the focus as determined by computed tomography. All recruited patients were graded by the National Institutes of Health Stroke Scale (NIHSS). Results: The results included the following findings: (i) the level of plasma SP in the PSD group (58.47 ± 14.39) was higher than that of the PS group (36.98 ± 9.49; P = 0.000), while the level of CSF SP in the PSD group (72.13 ± 13.06) was higher than that of the post‐stroke group (37.30 ± 12.57; P = 0.03); (ii) the level of plasma SP was positively correlated with the HAMD and NIHSS score; (iii) the level of plasma SP (38.45 ± 12.23), the HAMD score (9.08 ± 8.72), and the NIHSS score (3.25 ± 1.90) of the anterior stroke group (51.21 ± 16.27, 17.46 ± 15.96, and 6.91 ± 3.30, respectively) were higher than those of the posterior stroke group (38.45 ± 12.23, 9.08 ± 8.7, and 3.25 ± 1.90, respectively; P = 0.017, P = 0.001, and P = 0.000, respectively). Conclusions: SP in the plasma and CSF of patients exhibited a close correlation with neural damage and the incidence of PSD. This study also suggested that anterior hemispheric strokes may play a significant role in development of PSD.  相似文献

Characteristics of post-stroke depression in Japanese patients   总被引:6,自引:0,他引:6  
Post-stroke depression (PSD) has an important impact on the quality of life of patients with stroke. We studied 100 stroke patients (mean age+/-SD: 64.6+/-11.6, range: 32-85 years) in the subacute phase (2-5 weeks after onset) and investigated the prevalence and clinical correlates of PSD in the subacute phase. The prevalences of PSD and major depression in the subacute phase evaluated by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, were 20.0 and 5.0%, respectively. These values were lower than those reported in Caucasian studies. The Zung Self-Rating Depression Scale (SDS) did not underestimate the presence of PSD and was thus considered valuable for the initial screening of PSD. However, SDS may overestimate PSD especially in patients with anxiety disorders or somatoform disorders and vice versa. Apathy was observed in 40.2% of patients; however, it was widely distributed and observed even in patients without serious depression.  相似文献

目的:探讨老年人脑卒中后抑郁(PSD)的临床特征和西酞普兰的疗效。方法:65岁以上首次发作的老年脑卒中患者230例,于卒中15天后进行日常生活能力(ADL)、汉密尔顿抑郁量表(HAMD)、简明智能量表(MMSE)评估,对伴有卒中后抑郁的患者给予西酞普兰治疗,3个月后随访,并与对照组比较。结果:经随访评估合并PSD患者90例,占39.1%;PSD的发生率与卒中类型无关;脑叶和左侧半球与PSD发生具有相关趋势(OR>1,P=0.10);抑郁组与无抑郁组患者ADL及MMSE评分比较差异有显著性意义(P<0.05);经抗抑郁治疗后,西酞普兰组患者的抑郁症状逐渐好转,HAMD及ADL评分明显改善。结论:PSD的发生率高达39.1%;PSD对ADL和MMSE可产生明显影响;西酞普兰治疗PSD有良好疗效。  相似文献
