【摘要】 目的 探讨轻度认知功能障碍的心理学特点及其危险因素。 方法 由神经专科医生采集2009年9-12月在神经内科门诊就诊患者106例的临床资料，进行简易智能量表（MMSE）、听觉词语测验（AVLT）、画钟测验（CDT）、日常生活功能量表（ADL）、Hamilton 抑郁量表（HDRS）及临床痴呆评定量表（CDR）等神经心理测试。根据检查结果分为MCI组与对照组。 结果 MCI组受教育年限低于对照组（Plt;0.05），高血压病、糖尿病、脑卒中史高于对照组（Plt;0.05）。Logistic多因素回归分析显示受教育年限和高血压病史与MCI密切相关。MCI组MMSE总分、CDT得分、AVLT即刻记忆、延迟记忆及长时延迟再认显著低于对照组，ADL评分及HDRS评分高于对照组（Plt;0.05）。 结论 高血压病是MCI的危险因素，较高的受教育年限是MCI的保护因素。MCI患者在多个神经心理学领域受损。【Abstract】 Objective To investigate the neuropsychological characteristics of mild cognitive impairment (MCI) and its risk factors. Methods The clinical data of 106 patients in our neurologic department from september to December 2009, were collected by neurologists,and tested them by Chinese version of the mini-mental state examination (MMSE) , auditory verbal learning test (AVLT) , clock drawing test (CDT)、activities of daily living (ADL)、Hamilton depression rating scale (HDRS) and clinical dementia rating scale (CDR). All subjects were divided into MCI patients group and the control group. Results Educational level was significantly lower and hypertension, diabetes mellitus and stroke history were significantly more in patients with MCI than the control. The factors associated with MCI in logistic regression analysis were lower educational level and hypertension. The scores of MMSE、CDT and AVLT of MCI were significantly lower than those of the control, and the scores of ADL and HDRS were significantly higher than those of the control (Plt;0.05). Conclusion Hypertension is the risk factor and high educational level is the protective factor for MCI. MCI patients are impaired in multiple neuropsychological domains.
Objective To investigate the effect of continuous positive airway pressure (CPAP) on sleep disorder and neuropsychological characteristics in patients with early Alzheimer’s disease (AD) combined with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A total of forty-two early AD patients with OSAHS were randomly divided into a CPAP combined treatment group (20 cases) and a simple medicine treatment group (22 cases). The changes of neurocognitive function were assessed by Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE) and Hopkins Verbal Learning Test-revised (HVLT). Patient Health Questionnaire-9 (PHQ9) was used to evaluate the depression mood changes. The sleep characteristics and respiratory parameters were evaluated by polysomnography. The changes of the patients’ sleep status were assessed by Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). The changes of sleep status, cognitive function and mood in the CPAP combined treatment group were compared before and three months after CPAP treatment, and with the simple medicine treatment group. Results After three months of CPAP treatment, the ESS, PSQI and PHQ9 scores in the CPAP combined treatment group were significantly decreased compared with those before treatment, whereas MoCA, MMSE and HVLT (total scores and recall ) in the CPAP combined treatment group were increased compared with those before treatment (P<0.05). After CPAP treatment, the respiratory parameters apnea hypopnea index in the CPAP combined treatment group was significantly lower than that before treatment (P<0.05), and the minimum blood oxygen saturation was significantly higher than that before treatment (P<0.05). However, the sleep characteristics and parameters did not show statistically significant changes compared with those before treatment (P>0.05). The ESS, PSQI and PHQ9 scores were significantly reduced in the CPAP combined treatment group compared with the simple medicine treatment group (P<0.05), while there was no statistically significant changes of cognitive scores between the two groups (P>0.05). Conclusions The degree of low ventilation and hypoxia is alleviated, and the daytime sleepiness and depression is improved in early AD patients with OSAHS after three-month continuous CPAP treatment. Cognitive function is significantly improved, whereas there is no significant change in sleep structure disorder.
ObjectiveTo compare the cerebral protective effect of unilateral and bilateral antegrade selective cerebral perfusion during total aortic arch replacement, particularly with respect to neuropsychological outcome.MethodsFrom June 2003 to March 2004, 16 patients who underwent total aortic arch replacement were randomly allocated to one of two methods of brain protection: unilateral antegrade selective cerebral perfusion (unilateral group, n =8) or bilateral antegrade cerebral perfusion (bilateral group, n =8). Preoperative and postoperative neurological examination, brain computed tomography(CT) scan, and cognitive function tests were performed.ResultsAll patients survived the operations and were discharged from hospital. No new brain infarction occurred. Transient neurologic dysfunction occurred in 1 patient of each group. There were no intergroup differences in the scores of preoperative and post operative cognitive function ( P gt;0.05).ConclusionBoth methods of brain protection for patients undergoing total aortic arch replacement result in favorable and similar effect of brain protection in term of cognitive function provided the circle of Willis is patent and collateral flow is adequate.
Aphasia is one of the common disabling lesions and sequelae in stroke patients. In post-stroke aphasia patients, impairments of non-verbal cognitive domain often occur, which seriously affect daily social contact and quality of life. Cognitive neuropsychological rehabilitation is a neuropsychological rehabilitation based on the development of cognitive neuropsychological theory. It is currently applied in the field of rehabilitation of brain cognitive function, opening up a new way for evaluation and treatment of post-stroke aphasia. This paper introduces the general features of the application of cognitive neuropsychological rehabilitation, expounds the evaluation model and treatment principles of cognitive neuropsychological rehabilitation, and discusses its application in the evaluation and treatment of post-stroke aphasia, so as to provide ideas for the linguistic and non-linguistic cognitive rehabilitation of post-stroke aphasia.
Objective To investigate the cognitive functions in people at high risk for schizophrenia.Methods Two hundred and twenty-two people at high risk for schizophrenia and 331 normal controls were assessed with 14 neuropsychological tests. Results The results of some neuropsychological tests in people at high risk for schizophrenia were worse than those in the normal controls. These tests included information, arithmetic, digital symbol, block design, logical memory, visual memory, Stroop test, verbal fluency, tower of Hanoi, WCST and CPT (Plt;0.01). The time for trail making test A in was longer in the group at high risk for schizophrenia than in the control group (Plt;0.05).Conclusion People at high risk for schizophrenia have general cognitive deficits. Attention and executive function may represent the genetic endophenotype for schizophrenia.
ObjectiveThrough neuropsychological assessment, explore the factors that may cause cognitive impairment in patients with focal epilepsy.MethodsCollected 53 epilepsy patients in outpatients and inpatients of Tianjin Medical University General Hospital from March 2016 to January 2020, including 25 males and 28 females, with an average age of (23.58±13.24) years old, and the course of disease (6.49±7.39), all met the 2017 ILEA diagnostic criteria for focal epilepsy, and there was no history of progressive brain disease or brain surgery. Carry out relevant cognitive assessments for the enrolled patients, use SPSS statistical software to conduct Spearman correlation analysis on the cognitive functions of the study subjects, and further analyze the related factors of cognition through Logistic regression analysis to clarify the factors related to cognition whether it may be a risk factor for cognitive impairment in patients with focal epilepsy.Results Spearman correlation analysis showed that the FIQ of patients with focal epilepsy was related to education level, age of onset, seizure pattern, total number of seizures, AEDs and EEG interval discharge side (P<0.05). Binary Logistic regression analysis shows that among all cognitive-related factors, only the number of AEDs (P=0.003) and EEG interval discharge (P=0.013) are the risk of cognitive impairment in patients with focal epilepsy factor.ConclusionIn the clinical treatment of epilepsy, seizures should be actively controlled, but the types of drugs should be minimized. When there are more than 3 kinds of drugs, surgical treatment or other non-surgical treatments can be considered. At the same time, the EEG should be reviewed regularly to understand the changes in epileptiform discharges between episodes.
