Nearly 1 in 10 older Veterans have dementia, which is a devastating condition that leads to a progressive loss of independence and functional status. Currently available dementia medications do not alter the disease course. Therefore, it is critically important to identify effective strategies for helping older Veterans living with dementia to enhance their functional status and quality of life. The investigators have developed a novel, integrative group movement program called Preventing Loss of Independence through Exercise (PLIE) that incorporates elements from Eastern and Western exercise modalities and is designed to build and maintain the capacity to perform basic functional movements while increasing mindful body awareness and enhancing social connection. Pilot study results suggested that PLIE is associated with meaningful improvements in physical function, cognitive function and quality of life as well as reduced caregiver burden. The goal of the current study is to perform a full-scale randomized, controlled trial to test the efficacy of PLIE in older Veterans with dementia.
A 20+ year randomized controlled trial (RCT) demonstrated the many benefits of a counseling and support intervention for spouse caregivers, the NYU Caregiver Intervention (NYUCI). The NYU Caregiver Intervention (NYUCI) is an evidence-based intervention that provides counseling and support for families involved in the care of a relative or friend with Alzheimer's Disease and Related Dementias (ADRD). Most notably, the NYUCI substantially reduced caregiver's depressive symptoms, improved their physical health, and extended the time persons with ADRD remained at home by an average of 1.5 years (Mittelman et al., AG14634, formerly MH42216; See http://www.ncbi.nlm.nih.gov/pubmed/17101889). The intervention is now being widely implemented in-person, but there are barriers that prevent many caregivers from receiving its benefits, including geographic distance; impediments to older adults leaving their homes; and travel considerations for counselors which make it impossible to provide the NYUCI in person. The goal of this study is to evaluate the efficacy of an online videoconferencing version of the NYUCI. This innovative application has massive implications for social service delivery to older adults, because it will make it possible to deliver an in-person intervention, via the internet, which is already evidenced based to older adult caregivers who cannot currently be served. It will create the online reservation and management technology linking counselors with families as well as the evidence of effectiveness of providing such services via secure video teleconferencing vehicles. The proposed Telehealth Technology for Distance Counseling (TTDC) and related online educational training modules will connect skilled providers to the families of persons with dementia without regard to geographic location. Implications for rural healthcare delivery are particularly persuasive. To the investigators knowledge, this will be the first large-scale TTDC to be developed and rigorously tested with a randomized controlled trial. The investigators hypothesize that such a system, coupled with online training for providers and families on tele- counseling and distance caregiving, will have similar benefits to those achieved with in-person counseling during the original NYUCI RCT. This project includes an online reservation and management technology linking counselors with families via secure videoconferencing vehicles. The Telehealth Technology for Distance Counseling (TTDC), and online technology developed as part of this overall effort, will connect skilled providers to the families of persons with dementia without regard to geographic location. The related online clinical modules (i.e., interactive, computer-based educational materials) developed as a part of this grant effort will prepare counselors to provide the intervention, and caregivers to utilize the internet software, to be able to participate in counseling. The TTDC will include a scheduling system to link counselors to families at their mutual convenience and assure delivery in a cost-effective manner. The TTDC has the additional potential to transform ADRD care in ethnic and culturally diverse communities by connecting highly trained NYUCI counselors with specialized language and cultural skills to families who would not have access to these resources locally. In this study investigators will have 240 caregivers navigate the online educational module and the online reservation system for connecting caregivers with social workers. Half of the caregivers will then be paired with social service providers to receive counseling over the telephone, and the other half with be paired with social service providers to receive counseling via Zoom, a video conferencing program.

Apathy in Dementia Methylphenidate Trial 2 (ADMET 2) is a Phase III, placebo-controlled, masked, 6 month, multi-center randomized clinical trial sponsored by National Institutes of Aging involving 200 participants with Alzheimer's disease (AD). ADMET 2 is designed to examine the efficacy and safety of methylphenidate as treatment for clinically significant apathy in AD participants. ADMET 2 will enroll participants from real world settings such as outpatient, nursing home, and assisted living facilities and will examine the effects of methylphenidate on apathy and cognition. ADMET 2 will also conduct careful safety monitoring.
This study will obtain data from urine in subjects administered flortaucipir in an Avid-sponsored study to augment the calculation of radiation dosimetry estimates.
This study evaluates the effectiveness of Behavioral Activation (BA) therapy vs Support and Information for reducing risk for emotional and cardiovascular diseases in Alzheimer's caregivers. Half of participants will receive BA and the other half will receive support and information.
When older patients develop cognitive problems - like memory loss - there may be any of several underlying causes, sometimes occurring in combination. Clinicians have a better chance of providing appropriate treatment if they understand what the cause of the problem is. A diagnostic tool can help the patient by helping the clinician to make a more accurate diagnosis. This study investigates whether a new diagnostic tool - beta amyloid imaging - may potentially improve medical practice. The tool can potentially improve practice only if it can influence clinical judgment. This study investigates whether the provision of beta amyloid imaging information influences clinical judgment. The investigators will conduct a survey that presents clinicians with descriptions of hypothetical older patients with cognitive complaints. Some of the respondents also receive beta amyloid imaging information. The investigators will test the investigators hypothesis that the information will affect diagnostic judgment and management recommendations by comparing the responses of clinicians who receive the beta amyloid information to the responses of clinicians who do not.
The purpose of this study is to refine and test the web-based delivery of a well-established in-person group program that provides information and education to informal caregivers (family and friends) of persons with Alzheimer's disease (or related illnesses).
General Investigational Plan Study Objectives The goal of this proposal is to determine whether enhancing brain glucose utilization minimizes cognitive decline in patients with Amnestic Mild Cognitive Impairment (AMCI) or mild Alzheimer's disease (AD) dementia. We propose a proof of concept double-blind, placebo controlled pilot study to determine if increasing brain thiamine availability with the investigational new drug benfotiamine, will minimize the decline in glucose utilization and slow the cognitive decline associated with the progression AMCI/AD dementia. Specifically, our objectives are two-fold: - To test whether increasing brain thiamine by administering 600 mg per day (300 mg/morning and 300 mg/evening) of benfotiamine for one year can slow cognitive decline in these patients as measured with the Alzheimer's Disease Assessment Scale (ADAS-COG). - To determine whether increasing brain thiamine availability with 600 mg (300 mg/morning and 300 mg/evening) per day of benfotiamine for one year can slow the decline in brain glucose metabolism in these patients as measured with Fluorodeoxyglucose Positron Emission Tomography(FGPET) in the posterior cingulate. We will also carry out the following secondary objectives: - Assess if there are differences in secondary clinical outcome measures (NPI, ADCSADL, CDR, Buschke) between benfotiamine and placebo groups and whether specific cognitive domains (ie: activities of daily living, learning and memory verbal memory, behavioral, etc.) are driving these changes. - Compare ADAS-COG change scores in the benfotiamine and placebo groups within and between strata that were defined by initial cognitive impairment, to attempt to identified the population that most benefits from benfotiamine. - Compare changes in glucose utilization between the benfotiamine and placebo groups in secondary Regions of Interest (ROIs) including the hippocampus, prefrontal regions and entorhinal cortex. - Compare changes in whole brain glucose utilization between the benfotiamine and placebo groups using statistical parametric mapping (SPM). - Assess the correlation between changes in glucose utilization with changes in ADAS Cog. - Determine if ApoE4 genotype alters the response to benfotiamine.
