Filter by:This is a prospective cohort study with the main purpose of predicting progression neurocognitive disorders in Thai population. The main predictor variables to be evaluated are plasma phosphorylated tau (p-tau) level and cognitive test scores, which will be combined using statistical/computational modeling. Additionally, it seeks to evaluate biomarkers for diagnosing disease pathologies, understand their correlation with clinical outcomes, and explore the socioeconomic impact of neurocognitive disorders. The study invites both participants for biospecimen collection, structured interviews, and cognitive examinations and schedules follow-up visits annually or biennially.
The ageing of the population is leading to an increasing number of older drivers on the roads. At the same time, the proportion of older people with pathological ageing and neurocognitive disorders (NCD) is increasing. In terms of road safety, this raises the question of whether these drivers should continue to drive or not. People with NCDs may not be aware of the presence, extent and progression of their cognitive impairment and the impact it can have on daily life, including driving. Despite their loss of autonomy and medical advice, 22% of people with major NCD continue to drive. In addition, the presence of minor NCD also puts people at a higher risk of road accidents. However, several studies demonstrated that an NCD does not lead to a systematic and immediate impairment of driving ability and abruptly stopping driving leads to health problems, such as the risk of depression and greatly reduces quality of life. It is therefore relevant to focus research on driving with people with NCD in order to have a reliable indicator of the person's abilities and the impact of their cognitive impairment on driving activity. The proposed study seeks to meet this need by studying the performance of people with NCD on a driving station (mini-simulator) while assessing their ability to evaluate their performance. To achieve this goal, people with NCDs will perform tasks on a driving simulator. In addition, after each task on the driving simulator, they will answer questions about how they evaluate their own driving. Two assessors will observe the participants' driving and will estimate their driving performance. By comparing the driver's self-assessment with the assessors' assessment, an "awareness score of driving ability" will be calculated to determine whether the driver correctly assessed his or her performance. Another project already underway aims to collect similar data from people without a diagnosis of NCDs (control group). The principal objective of the present study is to compare the driving performance in a simulator and the awareness of driving ability of people with NCDs with those of a control group. Secondary objectives are : 1. to measure driving performance in a simulator and awareness of driving abilities (i.e. self-assessment skills) of people with NCDs. 2. to analyse driving performance and awareness of driving abilities according to the diagnosis and severity of the disorder (i.e. minor or major neurocognitive disorders). 3. to establish a methodology to identify a driver at risk of dangerous driving. It is mainly an exploratory study however some hypotheses can be made : - The driving performance and awareness of driving skills of people with NCDs are poorer compared to those of older, control individuals. - Individuals' driving performance and awareness of driving ability are lower in the presence of major NCDs compared to minor NCDs.
Perioperative neurocognitive disorders is a common postoperative complication in elderly surgical patients. The role of gut microbiota in cognitive function has been concerned in recent years. Studies suggests that gastrointestinal surgery may affect the gut microbiota, and the effect varies between surgical procedures. In this study, the investigators will compare the differences of gut microbiota between total gastrectomy and double-tract reconstruction, to investigate the effect of gastric acid on the gut microbiota colonizing, and the effect of different surgical procedures on the postoperative cognitive function of proximal gastric cancer patients.
The investigators aim to 1) investigate and compare the safety, efficacy and sustainability of hf-tRNS, tACS and sham transcranial current stimulation (tCS) over left inferior parietal lobe (IPL) in mild neurocognitive disorder due to vascular disease (NCD-vascular) patients with sleep disturbances; 2) examine the relationship between the changes in sleep quality, cognitive function and brain morphometry. Methods: Chinese right-handed mild NCD-AD patients with sleep disturbances (aged from 60 to 90 years) will be randomly assigned to a 2-week intervention of either hf-tRNS, tACS, or sham tCS, with 10 participants per arm. Before intervention, structural magnetic resonance imaging (MRI) data is used to construct individual realistic head model. Comprehensive assessments, including sleep quality, cognitive performance and blood pressure will be conducted at baseline, 2th week, 6th week and 12th week. Program adherence and adverse effects will be monitored throughout intervention.
Patients presenting with mild symptoms of acute ischemic stroke are common and account for approximately half of all acute ischemic stroke. About 30% of patients with minor stroke have a 90-day functional disability. Radiologically proven a large vessel occlusion (LVO) in patients with minor stroke is a well-established predictor of poor outcomes, while the poor outcomes following best medical management in patients with minor stroke with the underlying presence of a LVO are mainly driven by the occurrence of early neurological deterioration (END). Considering the well-known strong association between lack of arterial recanalization and END, endovascular therapy (EVT) appears as an attractive option to improve functional outcomes for LVO-related patients with stroke with mild symptoms. Whether EVT is safe and effective in patients with mild stroke with an LVO is currently debated, since these patients were typically excluded from the pivotal EVT trials. The current study aimed to further test the hypothesis that endovascular therapy would be superior to medical management with respect to functional recovery among low NIHSS patients caused by acute large-vessel occlusion in the anterior circulation.
To investigate factors that predict cognitive enhancement following engagement in an intensive Computerized Cognitive Training Protocol.
A 2-arm (sequence), 2-period, 2-treatments, single blinded (outcome assessor), randomized crossover-trial (12+12 weeks with immediate contrast) comparing a low-carbohydrate-high-fat diet (LCHF) with a high-carbohydrate-low-fat diet (HCLF) among individuals with prodromal Alzheimer's disease.
The study tests the effect of the ATNC MDD-V1 on Alzheimer patients' cognitive function. The ATNC MDD-V1 uses non-invasive stimulation of both magnetic and cognitive training.
The goal of this clinical trial is to verify that virtual reality is tolerably compatible with apathetic pathologies in patients and residents with major neurocognitive disorders. The main questions it aims to answer are: - Does virtual reality have an impact on symptoms of apathy in the elderly? - Is virtual reality well tolerated by the elderly? Participants will benefit from a 3-session virtual reality headset program with a healthcare professional. They will have one session per week for 3 weeks. They will be observed by another professional, who will complete observation grids on apathy, engagement in activity and tolerance of the virtual reality headset. There is not a comparison group: Researchers will compare the scores before and after the intervention: the participant will be his own control.
Traditionally, general anesthesia is maintained with inhalational anesthesia (GAS), but there is a gap in knowledge regarding whether intravenous anesthesia (IV) can prevent deleterious postoperative outcomes in the geriatric surgical population. The goal of this clinical trial is to determine whether intravenous anesthesia (IV) leads to a decreased incidence of postoperative delirium (POD), postoperative cognitive dysfunction (POCD), and functional decline, and improved patient-reported outcomes (PROs) in older adults undergoing non-cardiac surgery when compared to the standard inhalational anesthesia (GAS). This single-center, 1:1 randomized, double-blind (patient & outcome assessor) clinical trial will compare inhalational vs. intravenous anesthesia on POD, POCD, functional status, patient-reported outcomes (PROs), and blood-based biomarkers in older patients undergoing elective, inpatient, non-cardiac surgery. Upon enrollment, 260 women and men ≥ 70 years undergoing elective noncardiac surgery under general anesthesia will be randomized to 2 groups: TIVA or GAS.
