2.Vascular dementia and vascular cognitive impairment.
Acta Academiae Medicinae Sinicae 2004;26(2):198-200
Vascular dementia (VaD) subtypes include multi-infarct dementia, subcortical ischemic vascular dementia, strategic-infarct dementia, etc. Poststroke dementia may be related to preexisting cognitive level, and the frequency increased with aging, lower educational level and accompanied vascular risk factors. Vascular cognitive impairment (VCI) forms a spectrum that includes VaD, mixed Alzheimer's disease (AD) with a vascular component, and VCI without dementia. The concept of VCI will improve the early diagnoses and secondary prevention and treatment of VaD, and promote the further research on vascular component in neurodegenrative disorders.

3.Effects of Family Support Programs for Caregivers of People with Dementia - Caregiving Burden, Depression, and Stress: Systematic Review and Meta-analysis.
Journal of Korean Academy of Nursing 2015;45(5):627-640
PURPOSE: The objective of this systematic review was to assess the effects of family support programs on caregiving burden, depression, and stress in family caregivers of people with dementia. METHODS: A literature search was conducted of electronic databases to identify randomized controlled studies with family support programs done between 2000 and 2014. Studies published in English and/or Korean were included for the analysis with search strategies adapted from the Cochrane Dementia and Cognitive Improvement Group. Studies were rated for quality assessment by two independent reviewers using the appraisal checklist developed by Cochrane Reviews and Dissemination. Of 8,334 articles identified in the literature search, full texts of 76 articles that met the inclusion criteria were reviewed and 38 were found to include relevant outcomes. RESULTS: Results from selected studies were pooled in statistical meta-analysis using Review Manager Software and heterogeneity between combined studies was assessed using the Chisquare test. Meta-analysis showed that the effect sizes of family caregiver support programs were small to medium for categories of caregiving burden (Hedge's g= - 0.17, 95% CI= - 0.30~ - 0.04), depression (Hedge's g= - 0.30, 95% CI= - 0.40~ - 0.20), and stress (Hedge's g= - 0.39, 95% CI= - 0.52~ - 0.25). CONCLUSION: The review results indicate that a support programs can assist family caregivers in reducing their psycho-emotional distress.

BACKGROUND:
Single subcortical infarction (SSI) is caused by two main etiological subtypes, which are branch atheromatous disease (BAD) and cerebral small vessel disease (CSVD)-related SSI. We applied the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ), the Shape Trail Test (STT), and the Stroop Color and Word Test (SCWT) to investigate the differences in cognitive performance between these two subtypes of SSI.
METHODS:
Patients with acute SSIs were prospectively enrolled. The differences of MoCA-BJ, STT, and SCWT between the BAD group and CSVD-related SSI group were analyzed. A generalized linear model was used to analyze the associations between SSI patients with different etiological mechanisms and cognitive function. We investigated the correlations between MoCA-BJ, STT, and SCWT using Spearman's correlation analysis and established cut-off scores for Shape Trail Test A (STT-A) and STT-B to identify cognitive impairment in patients with SSI.
RESULTS:
This study enrolled a total of 106 patients, including 49 and 57 patients with BAD and CSVD-related SSI, respectively. The BAD group performances were worse than those of the CSVD-related SSI group for STT-A (83 [60.5-120.0] vs. 68 [49.0-86.5], P = 0.01), STT-B (204 [151.5-294.5] vs. 153 [126.5-212.5], P = 0.015), and the number of correct answers on Stroop-C (46 [41-49] vs. 49 [45-50], P = 0.035). After adjusting for age, years of education, National Institutes of Health Stroke Scale and lesion location, the performance of SSI patients with different etiological mechanisms still differed significantly for STT-A and STT-B.
CONCLUSIONS
BAD patients were more likely to perform worse than CSVD-related SSI patients in the domains of language, attention, executive function, and memory. The mechanism of cognitive impairment after BAD remains unclear.

Asian Nursing Research 2016;10(2):128-135
PURPOSE: In Korea, most elderly with dementia receive care from family members, yet little research is available on the experience of dementia-related anxiety in middle-aged female caregivers for a family member with dementia. The purpose of this study was to describe the lived experience of dementia-related anxiety in middle-aged female caregivers for family members with dementia. METHODS: A descriptive phenomenological study was conducted. A purposive sampling strategy was used to recruit participants. Twelve middle-aged women (40-59 years, mean age = 51.90 years) who were family caregivers were interviewed from February 2014 to August 2014. Data were collected through semistructured interviews and analyzed using Giorgi's method. RESULTS: The essential structure of the phenomenon was a fear of losing self-identity. The main essence was represented by six components: keenly feeling the effects of aging because of memory deficit, continuous comparison of the family member's behavior with that of the participant's, Finding it painful to see a family member with dementia as he/she does not know how this will end, not knowing the conclusion of the disease process, reducing the risk of dementia, and trying to change one's lifestyle from what it used to be in the past. CONCLUSIONS: The study provides the essential structure of the experience on dementia-related anxiety that caregivers of a family member with dementia have. The findings could help healthcare providers and researchers have better understanding of dementia-related anxiety and give more attention to the caregivers to relieve their anxiety

Journal of Peking University(Health Sciences) 2022;54(6):1158-1162
OBJECTIVE:
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with high morbidity and mortality. There are about 5%-15% of ALS patients combining with frontotemporal lobe degeneration (FTLD) at the same time and 50% of patients combing with cognitive function changes. The analysis of cortical thickness based on MRI is an important imaging method to evaluate brain structure. The aim of the study was to explore the changes of brain structure in ALS patients by cortical thickness analysis, and to explore the correlation between the brain structure and cognitive function.
METHODS:
In the study, 18 ALS patients treated in Department of Neurology, Peking University Third Hospital and 18 normal controls (age, gender and education level matched) were included. 3D magnetization prepared rapid gradient echo imaging (MPRAGE) sequence MRI was performed and the cortical thickness was analyzed. At the same time, all the ALS patients took neuropsychology assessments, including: mini-mental state examination (MMSE), verbal fluency test (VFT), Stroop color word test (SCWT), prospective memory (PM), emotional picture perception and recognition, and faux pas story test.
RESULTS:
After cognitive assessment, two ALS patients had cognitive impairment. One was in accordance with ALS-frontotemporal dementia (FTD) diagnosis and the other one was in accordance with ALS cognitive impairment (ALSci) diagnosis. In all the 18 ALS patients and 18 normal controls, the cortical thickness of the left medial orbitofrontal lobe and the medial temporal lobe were significantly reduced (P < 0.05) in ALS group by the vertex-wise comparison. Cortical thickness of the left entorhinal cortex, the left inferior temporal gyrus, the left medial orbitofrontal lobe and the left insular lobe was significantly reduced (P < 0.05) by the region-wise comparison. However, when only concluded the 16 ALS non-cognitive impairment patients, there was no significant difference between the two groups (P>0.05). There were correlations between the scores of prospective memory, emotional picture perception and recognition, faux pas story test and the cortical thickness of their corresponding regions (P < 0.05).
CONCLUSION
The cortical thickness of ALS patients are correlated with neuropsychological scores which may reflect the changes of cortical structure corresponding to the cognitive assessment, and may provide help for the early diagnosis of cognitive changes in ALS patients.

OBJECTIVES:
Perioperative neurocognitive disorders (PND) is one of the important factors affecting the recovery of the elderly after surgery, and sleep disorders are also one of the common diseases of the elderly. Previous studies have shown that the quality of postoperative sleep may be factor affecting postoperative cognitive function, but there are few studies on the relationship between preoperative sleep disorders and postoperative cognitive dysfunction. This study aims to explore the relationship between preoperative sleep disorders and postoperative delayed neurocognitive recovery in elderly patients, and provide references for improving the prognosis and quality of life of patients.
METHODS:
This study was porformed as a prospective cohort study. Elderly patients (age≥65 years old) underwent elective non-cardiac surgery at Xiangya Hospital of Central South University from October 2019 to January 2020 were selected and interviewed 1 day before the operation. The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) were used to assess the patient's baseline cognitive status. Patients with preoperative MMSE scores of less than 24 points were excluded. For patients meeting the criteria of inclusion, Pittsburgh Sleep Quality Index (PSQI) scale was used to evaluate the patients, and the patients were divided into a sleep disorder group and a non-sleep disorder group according to the score. General data of patients were collected and intraoperative data were recorded, such as duration of surgery, anesthetic time, surgical site, intraoperative fluid input, intraoperative blood product input, intraoperative blood loss and drug use. On consecutive 5 days after surgery, Numerical Rating Scale (NRS) was used to evaluate the sleep of the previous night and the pain of the day, which were recorded as sleep NRS score and pain NRS score; Confusion Assessment Method for ICU (CAM-ICU) scale and Confusion Assessment Method (CAM) scale were used to assess the occurrence of delirium. On the 7th day after the operation, the MMSE and MoCA scales were used to evaluate cognitive function of patients. We compared the incidence of postoperative complications, the number of deaths, the number of unplanned ICU patients, the number of unplanned secondary operations, etc between the 2 groups. The baseline and prognosis of the 2 groups of patients were analyzed by univariate and multivariate logistics to analyze their correlation.
RESULTS:
A total of 105 patients were collected in this study, including 32 patients in the sleep disorder group and 73 patients in the non-sleep disorder group. The general information of the 2 groups, such as age, gender, body mass index, and surgery site, were not statistically significant (all
CONCLUSIONS
Preoperative sleep disorders can increase the risk of delayed neurocognitive function recovery in elderly patients. Active treatment of preoperative sleep disorders may improve perioperative neurocognitive function in elderly patients.

OBJECTIVETo investigate the sleep structure in patients with vascular cognitive impairment-no dementia (VCI-ND) and its differences from that of normal individuals.
METHODSThe whole night sleep record of 20 patients with VCI-ND were monitored by 32-head video-taped polysomnographic system, and the results were compared with the data of 20 normal subjects.
RESULTSCompared with normal subjects, patients with VCI-ND showed significantly reduced total sleep duration, increased waking times, increased stage 1 sleep, decreased stage 2 sleep, decreased stage 3 sleep, decreased rapid eye movement stage (REM) and reduced sleep efficiency.
CONCLUSIONIncreased light sleep as well as decreased slow-wave stage 3-4 sleep and decreased REM stage may be a specific electroneurophysiologic marker for VCI-ND, but large-sampled multi-centered randomized controlled trial is necessary to test the validity of these features as specific markers for screening and early diagnostic purposes.
