A Multi-domain Lifestyle Intervention Among Aged Community-residents in Zhejiang, China
Cognitive ImpairmentAlzheimer Disease8 moreA study conducted in Finland discovered that a multidomain intervention, consisting of physical activity, nutritional guidance, cognitive training, social activities, and management of vascular risk factors, effectively decelerated cognitive decline in healthy older adults who were at an increased risk of cognitive decline. The HERITAGE study is a 2-year clustered randomized controlled trial (clustered-RCT) that explores the efficacy of a multidomain intervention among 1200 elderly residents with a higher risk of cognitive decline and dementia in Zhejiang Province, China
Effects of t-DCS and Cognitive Training on Apathy in Elderly With Minor Neurocognitive Impairment...
ApathyNeurocognitive DisordersTranscranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique using a low intensity electric current to modify cortical excitability. Apathy is a pervasive neuropsychiatric symptom characterized by a reduction in goal-directed behavior and activity that persists over time and causes identifiable functional impairment. The aim of this study is to evaluate the effects of repeated sessions of tDCS combined with simultaneous cognitive training on apathy in older people with minor neurocognitive disorders.
Cognitive Outcomes After Dexmedetomidine Sedation in Cardiac Surgery Patients
DeliriumCognitive Dysfunction16 moreAnesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.
E-health and People Living With Major Neurocognitive Disorder - CARE© and ESOGER© Applications
Major Neurocognitive DisorderFrailtyThe care pathways of people living with major neurocognitive disorders (MNCD) are often inadequate due to poor access to resources, long delays, and resources that are poorly adapted to expectations and needs. This situation was exacerbated during the coronavirus disease (COVID-19) pandemic due to the reduction of available resources and care provider burnout. People living with MNCD are at risk of becoming more fragile, which can lead to emergency room visits and hospitalizations, and significantly alter the quality of life of the dyad (family caregiver and the person being cared for). Intervening earlier in the care pathway would make it possible to avoid the aggravation of pathologies associated with MNCD and hospitalizations. The reorganization of activities imposed by the social distancing measures due to the pandemic has shown that e-health is a solution to maintain access to resources for people living with chronic conditions such as MNCD. We have been working since the beginning of the pandemic on the development of two complementary health applications for seniors and their dyads: the self-assessment questionnaire on frailty (CARE©) and the Evaluation et orientation SOcio-GÉRiatrique (ESOGER©) questionnaire : CARE© is made by the dyad, allowing to identify a state of frailty and the risks related to it. It relies on the active participation of the user and is deployed in the form of an application. ESOGER© is a standardized hetero-questionnaire filled out remotely, during a telephone call, by a community organization worker with the user and/or his/her caregiver. It is a tool for first contact, listening and accompanying a user, which makes it possible to determine whether the needs for care and services are being met, to prioritize the needs, to trigger the implementation of care and services, and to make the link with the organizations providing care and services. The objectives of this study are to examine the effects of CARE© combined with ESOGER© on the state of physical and mental frailty, loss of autonomy, quality of life, and consumption of health services and care resources in people living with a major neurocognitive disorder (MNCD).
SV2A & TSPO PET Imaging Measures to Reveal Mechanisms of HIV Neuropathogenesis During Antiretroviral...
HIV Associated Neurocognitive DisorderHIV Dementia2 moreThe purpose of this study is to longitudinally characterize and evaluate changes in synaptic density in the brain using novel positron-emission tomography (PET) scans; magnetic resonance imaging (MRI), and clinical laboratory markers associated with HIV-related injury in the central nervous system. This study will test hypotheses relating to the presence and mechanisms of aberrant brain structure at the synaptic level in living humans with virologically controlled HIV on antiretroviral therapy. To evaluate associations between PET imaging radiotracers [11C]UCB-J, a ligand for presynaptic vesicle protein 2A (SV2A), a vesicle membrane protein expressed in synapses, and PET [11C]PBR28 a measure of microglia function in the brain, the Yale PET center has developed an advanced approach of combining multiple distinct ligands in coordinated same-day PET imaging. Additionally, the study will evaluate the associations of this novel synaptic density marker with well-established clinical measures of neurocognitive performance and laboratory measures of blood and cerebrospinal fluid (CSF).
The SINgapore GERiatric Intervention Study to Reduce Cognitive Decline and Physical Frailty (SINGER)...
Cognitive ImpairmentAlzheimer Disease8 moreA study in Finland found that a multidomain intervention of physical activity, nutritional guidance, cognitive training, social activities and management of vascular risk factors slowed cognitive decline in healthy older adults at increased risk of cognitive decline. A 6-month pilot study was initiated in Singapore, which demonstrated the cultural feasibility and practicality of the FINGER interventions and a set of locally adapted interventions in an Asian population. The SINGER study is a 2-year randomized controlled trial that aims to test the efficacy and safety of these lifestyle changes, including diet and cardiovascular risk factor management, cognitive and physical exercises, in delaying cognitive decline in older adults at risk of dementia.
Benefit of Virtual Reality Headset Use on Apathy in Older Adults With Major Neurocognitive Disorders...
Apathy in DementiaAged2 moreThe 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.
Virtual Reality Intervention for the Reduction of Behavioral and Psychological Symptoms of Dementia...
DementiaAlzheimer's Disease1 moreAlzheimer's disease and related disorders (AD2) are characterised by cognitive changes and Behavioural and Psychological Symptoms of Dementia (BPSD). According to the French National Authority for Health (2009), Non-Pharmacological Interventions (N PhIs) are to be favo red in the treatment of BPSD. A few NPhIs have already shown their effectiveness in the management of these symptoms, such as music therapy or multi-sensory stimulation, but these techniques require trained staff and/or adapted premises. Over the past decade, innovative techniques have emerged in the field of NPhIs. Virtual Reality (VR) is one of them. Amongst the VR tools, the LUMEEN technology offers a suitable mediation tool for older adults with disabilities which allows to show immersive experiences in calm landscapes known to bring a feeling of well-being (beach, mountain, dolphins, classical music concert, animals in nature, etc.). The main objective of this study is to evaluate the effect of the LUMEEN Evasion module on the occurrence of BPSD in older adults living in residential aged care. Participants will be recruited in nursing homes and randomly assigned to the LUMEEN intervention group or the control group. Participants in the LUMEEN intervention group will attend 12 LUMEEN group session s in which they will be immersed for a few minutes in a selection of landscapes or scenes using virtual reality head-mounted displays and will then have a group discussion about the immersive experience they watched during the session. Participants in the control group will attend 12 non-digital (sensory, social, cognitive, creative) stimulation group sessions in which they will carry out typical pen-and-paper activities for this public which mainly stimulate language, immediate memory, semantic memory, and visual recognition (e.g., definitions, games of 7 differences, reconstruction of proverbs, quizzes…). The BPSD will be evaluated by the healthcare team before the start of the intervention and after the 12 sessions in both arms of the study (LUMEEN intervention and control) using the Neuropsychiatric Inventory filled out by the nursing staff (NPI). LUMEEN sessions are expected to reduce BPSD (especially apathy) more than control sessions. Thus, participants in the LUMEEN intervention group should have a greater difference between baseline and post-intervention NPI scores than the participants in the control group (in the direction of a reduction of the symptoms in the post-intervention evaluation). Secondary outcomes will also be measured focusing on apathy, well-being and social interactions. First of all, apathy will be evaluated thanks to the Apathy Inventory - Clinician before and after the interventions in both groups. Then, the state of well-being of the participant will be evaluated thanks to the EVIBE scale completed before and after each session. In addition, social interaction behaviors will be rated using the Social Behaviour Resident Index (SOBRI), collected through a 4-minutes participant observation during each session by an external observer. LUMEEN sessions are expected to improve these three outcomes more than control sessions. Differences are expected to be observed between the two groups : a) apathy should be lower after the sessions than before and the pre-post-intervention difference should be larger in the LUMEEN intervention group than in the control group; b) well-being should be (in average) higher after the sessions than before and the pre-post-intervention difference should be larger in the LUMEEN intervention group than in the control group ; and c) there should be, on average, more social interactions behaviours during the LUMEEN sessions than during the control sessions.

Major Neurocognitive DisorderThe model of care tested in the GPS project aims to optimize pharmacotherapy for seniors undergoing cognitive assessment or suffering from major neurocognitive disorder (MCND) at home. The goal is to reduce polymedication, inappropriate medications and the treatment burden of seniors and to maintain their cognitive health, quality of life and autonomy. The intervention will include knowledge exchange sessions with nurses, pharmacists, and doctors in FMGs, and increased collaboration between these professionals and home care services teams. Other goal is to increase the satisfaction of the seniors, their families, and the professionals involved in the GPS project.
Intranasal Insulin Improves Postoperative Neurocognitive Disorders in Elderly Patients
Postoperative Neurocognitive DisordersPostoperative neurocognitive disorders (PND) are common postoperative complication of central nervous system, leading to increased risk of the working ability loss after surgery, longer hospital stay, increased medical costs and increased surgical mortality. It is classified as perioperative neurocognitive disorders in mental disorders.Aging is an important demographic characteristic in China, and the elderly is also a population susceptible to PND. There is a lack of targeted prevention and control measures for PND. Central insulin resistance is an important mechanism of cognitive impairment in elderly patients, and exogenous supply of central insulin may be an important measure to improve PND. Compared with conventional subcutaneous and intravenous supply, intranasal insulin administration not only has little effect on blood glucose and insulin levels, but also enters the center through the blood-brain barrier easily and efficiently. Long-term use of intranasal insulin can improve the cognitive function of chronic diseases, but there is a lack of clinical studies on improving PND by intranasal insulin. This study will verify the effectiveness of intranasal insulin in the PND improvement of elderly patients.
