Safety measurement will be evaluated by medical history, vital signs, physical examinations, laboratory examinations and collecting of adverse events. This study is expected to be completed in a period of 3 years.
Enhancing Everyday Autonomy for People With Dementia
DementiaDementia is a highly disabling major neurocognitive disorder. Although cognitive symptoms drive the diagnosis of dementia, neuropsychiatric symptoms (NPS), such as agitation, aggression, and psychosis, are common and associated with increased morbidity/mortality, increased care partner distress, and earlier institutionalization. Although these symptoms are debilitating and experienced by more than 90% of people with dementia, there are currently no FDA-approved treatments. There remains a critical need for safe and effective interventions for NPS that can be easily administered and monitored in typical clinical settings. One hypothesis for the etiology of NPS is that, as cognitive impairment progresses, there is a decline in the sense of autonomy and an increase in unmet needs that a person with dementia (PWD) is unable to meet on his/her own and that care partners lack the knowledge or ability to meet. As care partners become increasingly involved as surrogate decision-makers for a PWD, the quality of life for a PWD is directly impacted by the decisions made by a surrogate. Several studies have explored agreement between PWDs and surrogate decision-makers regarding various preferences. Results have indicated that discrepancy between a PWD's preferences and those identified by a surrogate decision-maker is common. According to our conceptual model, such discrepancy may give rise to NPS. Thus, the proposed pilot project directly addresses major gaps in the availability of safe, effective, and accessible strategies to reduce NPS and NPS-related care partner distress by developing and testing a novel educational intervention that directly targets discrepancies regarding everyday preferences. We will randomize 30 dyads comprising people with clinically significant cognitive impairment (mild cognitive impairment or dementia) and their care partners. The dyads will be randomized to either 1) the intervention arm in which there is a clinician-facilitated discussion between the dyad pair about NPS, the unmet needs hypothesis, and areas of discrepancy in everyday preferences and 2) the enhanced usual care arm in which a standardized document describing NPS and the unmet needs hypothesis will be given to the dyad to review. Primary efficacy will be measured by the Neuropsychiatric Inventory brief questionnaire form (NPI-Q), which allows for assessment of both NPS burden as well as burden of caregiver stress. Assessments will be made at baseline, week 4, and week 8.
Daily Sleep Enhancement for Hospitalized People With Dementia Following a Nursing Protocol
SleepDementiaThe purpose of this study is to determine if the daily performance of a 7 step bedtime nursing protocol for hospitalized people living with dementia is feasible and if it has an effect on bedtime and daytime variables.
Dementia Caregiver Chronic Grief Management: A Live Online Video Intervention
Chronic GriefDementia Family CaregiversThe exponential rise in the number of persons diagnosed with Alzheimer's disease and related dementias (ADRD) places a heavy burden on family caregivers. The caregiver role that extends well beyond the placement of the care recipient in long-term care is associated with chronic grief, depressive and anxiety symptoms, dissatisfaction with care, and conflict with long-term care facility staff. This study will test the effects of a cost effective chronic grief management intervention to be delivered using an online platform (Adobe Connect) and iPads. The study aims to decrease dementia caregivers' chronic grief, depressive and anxiety symptoms, and to improve their positive states of mind; to improve satisfaction with care post-placement and to attenuate caregivers' conflict with facility staff.
Computerized Cognitive Intervention in the Oldest-Old
CognitionDementiaLittle is known about preventive strategies with immediate public health impact for cognitive functioning in the oldest-old (OO). Cognitive training improves cognitive functioning in the young-old (YO; 60 to 84), yet has not been examined in the OO. Clinical trials are needed to determine if computerized cognitive training is effective at preventing or delaying cognitive decline in the OO. In order to develop such trials, information regarding use of computers and internet by the OO, and the ability and interest in such a program, must be determined. This study will examine the effects of a computerized cognitive training program, CogniFit™, with a "classic" computerized games program, on cognitive functioning in cognitively healthy OO subjects. Information regarding use of computers and internet by the OO will be collected. Interest in and ability to complete a computerized cognitive training program will be examined, along with the cognitive, demographic, biological, and lifestyle characteristics related to this interest and ability. Efficacy of the CogniFit™ and games programs will be assessed immediately following the training and four months after completing the training. The researchers expect that those who use the CogniFit™ program will have greater improvements than those using the games program. Finally, the participants' characteristics related to the efficacy of the programs will be examined. Subjects recruited for this project will include those already participating in several studies of aging and cognition at the Mount Sinai School of Medicine. Recruiting from this pool of subjects will provide this program with baseline information regarding numerous subject characteristics, including cognition, family history, lifestyle, and cardiovascular information. This study will inform future large-scale clinical trials of computerized cognitive training programs in the elderly, as well as provide information regarding the efficacy of such training in the OO. In addition, the study will identify characteristics affecting efficacy of computerized training, and thus, may suggest mechanisms through which cognitive training improves cognitive functioning in the most senior citizens of our society.
A Multidomain Approach to Preventing Dementia in African Americans: Cognitive Prescriptions

Team-based Technology-enabled Integrated Patient/Caregiver-focused Dementia Study
DementiaDementia patients experience memory and other cognitive function deterioration leading to loss of independent function. Care required for dementia is multifactorial, spanning cognitive, behavioral, emotional, and physical symptoms, and complicates aspects of daily living. This places tremendous strain on caregivers who, in turn, experience their own increased physical and mental health needs. The current care model focuses primarily on patient pharmacological management but misses the mark on caregiver focus and collaboration. Building on systematic reviews and existing evidence gaps in information and support for patient/caregiver dyads, dealing with behavioral symptoms, referrals to available community resources, and multidisciplinary team care with improved coordination and communication17, the study investigators propose a patient- and caregiver-targeted Integrated Dementia Practice Unit (IDPU) model of care. IDPU integrates disconnected care under a centralized specialty team, providing monitoring, education, individualized support, and proactive, ongoing collaboration and coaching using technology and home/virtual visits for maximal impact. Days alive at home (DAAH) best captures quality of life (QOL) for the index dementia patient, from the perspective of both the healthcare system and the caregiver, and degree of support for the caregiver and is often an outcome in assessing health delivery. The study investigators hypothesize IDPU will increase DAAH and improve patient-level (behavioral; depressive symptoms; chronic disease management) and caregiver-level (strain, depressive symptoms, social support) outcomes relative to an Educational+ model, merging a standard care design with additional education support for patients/caregivers and their Primary Care Providers (PCP). This study seeks to (a) improve and establish IDPU feasibility of the in the feasibility phase, (b) determine if IDPU is more effective than Education+ in increasing DAAH and patient- and caregiver-level outcomes, and (c) determine if benefits of IDPU are more or less pronounced in vulnerable subgroups in the full-scale study.
Assessment of Social-emotional Functioning in Neurological Diseases
Alzheimer DiseaseStroke3 moreEmpathy, defined as the ability to understand others emotions, is a fundamental concept in social interactions. It is a psychological phenomenon involving various separable components : (i) the ability to feel and imagine the emotions, (ii) the ability to adopt the perspective of other people. Several neurological diseases with behavioral disorders may lead to impaired processing of social and/or emotional informations. These pathologies are likely to induce a lack of empathy that may result from impairments at different levels. The objective is simply to study how others' emotions are understood and how this allows for regulation of personal behavior. This study is being carried out among patients seen for various health problems and who can make behavior changes. This study could help to understand some neurological diseases and thereby to identify them earlier and/or to better differentiate them.
