Attention Modulation for Treatment of Parkinson's Disease and Dementia With Lewy Bodies

Parkinsons DiseaseLewy Bodies Disease

The purpose of this study is to evaluate if a drug commonly used to treat excessive day-time sleepiness, called armodafinil (Nuvigil), is also effective in improving the impairment in the attention commonly reported by patients with more advanced Parkinson's disease (PD) and Lewy body disease (LBD).

Diagnostic Evaluation of Dementia With Lewy Bodies Using a Multimodal Approach

Lewy Bodies DiseaseAlzheimer Disease1 more

Dementia with Lewy body disease (DLB) is the second leading cause of degenerative cognitive disorder after Alzheimer's disease (AD). Its variable clinical expression makes diagnosis difficult. To date, there is no validated DLB diagnostic biomarker, despite several biomarkers in development (EEG, MRI, biology). Studies have shown that an improvement in diagnostic performance could be obtained by combining different modalities biomarkers using machine learning. The aim of this research is to identify the best combination of multimodal biomarkers for the diagnosis of DLB (EEG, MRI, biology, cognitive scores), using a machine learning approach applied to a clinical cohort.

A Study of Neurodegeneration and Neuronal Fluctuations in Lewy Body Disease and Alzheimer's Disease...

Lewy Body DiseaseAlzheimer Disease1 more

The purpose of this research study is to investigate how the brain, memory, thinking, and motor behavior change both in individuals with movement and/or cognitive disorders, as well as healthy individuals. Researchers will look at measurements of memory, thinking, brain wave and muscle activity, daily functioning, and brain scans to learn more about brain disorders such as Alzheimer disease and Lewy body disease.

Optical Neuroimaging and Cognition

Dementia With Lewy BodiesAlzheimer Disease1 more

Dementia is associated with a variety of neurovascular and neurometabolic abnormalities. Traditional imaging techniques used to investigate such abnormalities, such as Positron Emission Tomography and functional Magnetic Resonance Imaging, are not always well tolerated, have expensive start up and running costs, and are limited with regards to the types of experiments that can be performed as they can be highly sensitive to movement, are noisy, and have physical restrictions. Near-infrared spectroscopy (NIRS) is a non-invasive neuroimaging technique which uses light in the near-infrared spectrum to detect relative changes in concentration of oxygenated and deoxygenated haemoglobin, and the oxidation state of Cytochrome C Oxidase. As such, NIRS can provide measures of brain oxygenation and metabolism. NIRS is less sensitive to movement, is well tolerated and has few contraindications. It is thus a promising candidate for use in clinics or in peoples' homes for monitoring dementia. In the present study, the investigators aim to use both dual-wavelength and broadband NIRS in a range of dementia subtypes, including Alzheimer's Disease and Dementia with Lewy Bodies, and severities, including Mild Cognitive Impairment, to identify how brain oxygenation and metabolism is altered in dementia and across various clinical subgroups. The investigators also aim to determine the relationship between brain oxygenation and metabolism in dementia, and use machine learning approaches to identify optical biomarkers for dementia.

Investigating Genetic Status in Patients Presenting to Clinic

DementiaFrontotemporal2 more

The causes of neurodegenerative dementias such as Frontotemporal Dementia, Lewy Body Disease and Alzheimer's disease are still largely unknown. While the contribution of some genetic mutations and polymorphisms is associated with autosomal dominant patterns of inheritance of these dementias, in many cases, the specific causative mutation in these families is not yet identified. Further, in many patients, polygenic risk is thought to give rise to pathophysiologic changes, but which specific genes affect risk are largely yet unknown. By examining genotypes in patients that present to our Cognitive Neurology and Alzheimer's Research Clinic with suspected or confirmed neurodegenerative dementia, or have a history of a familial dementia, we aim to help identify and characterize genetic mutations or polymorphisms that give rise to neurodegenerative diseases.

Learning to PERSEVERE: Peer Mentor Support and Caregiver Education in Lewy Body Dementia

Lewy Body DiseaseParkinson Disease Dementia1 more

The investigators propose to adapt, improve, and implement a peer mentor support and caregiver education (PERSEVERE) program to improve LBD-specific caregiving mastery. Lewy body dementia (LBD) is the second most common dementia, comprising Parkinson's Disease (PD) dementia and Dementia with Lewy Bodies. LBD causes deterioration in multiple cognitive, motor, and neuropsychiatric domains, leading to heavy reliance on family caregivers. Patients with LBD are at a far greater risk of hospitalizations for falls, neuro-psychiatric symptoms, and infections, which are often preventable or treatable at home if recognized. Studies cite a crucial need for education and support of LBD caregivers, who face high rates of caregiver strain and adverse outcomes. Evidence from other chronic conditions supports peer mentoring as a potentially effective intervention to provide education and social support. PERSEVERE builds on our team's ongoing work of creating and testing a peer mentoring program for homebound PD patients' caregivers that has shown promising feasibility and acceptability. In the proposed project, the investigators will convene focus groups of former mentors and mentees, along with current caregivers, to provide formative information to shape the revised PERSEVERE curriculum that will include in-person mentor training and a comprehensive mentoring handbook. The curriculum will focus on key areas of LBD caregiving mastery, including: fall prevention, infections, neuropsychiatric symptoms (particularly hallucinations, delusions, anxiety, and depression), and advance directives. The investigators will enroll and train a new cohort of 36 LBD caregiver peer mentors who will be matched with 30 current LBD caregivers. Each pair will be instructed to speak on a weekly basis, using the 16-week structured curriculum as a framework. The study team will support the mentors with monthly conference calls and day-to-day availability for concerns. The investigators will assess the feasibility and fidelity of the intervention via online study diaries tracking the frequency, duration, and content of calls. During mentor training, the investigators will assess the change in mentors' caregiver mastery and LBD knowledge pre- and post-training. During the PERSEVERE intervention, the investigators will determine the change in mentees' caregiver mastery, LBD knowledge, and loneliness.

Care Ecosystem: Navigating Patients and Families Through Stages of Care

DementiaAlzheimer Disease5 more

This is a randomized clinical trial evaluating the benefits of a program that supports model care for persons with dementia and their family caregivers. Subjects were recruited from California, Nebraska and Iowa. Subjects determined to be eligible were consented and randomized into one of two groups. Two thirds of patients were enrolled into Navigated Care that provided them with assistance in meeting important benchmarks in their care, for example completion of legal and financial planning and strategies for minimizing caregiver burden. One third of patients were enrolled to a control group, entitled Survey of Care. Outcomes include quality of life, health care utilization, caregiver burden, satisfaction with care, caregiver depression, and caregiver self-efficacy.

A Relational Research Recruitment and Engagement Intervention for Cognitive Aging Research

DementiaCognitive Dysfunction3 more

Despite well-documented disparities in Alzheimer's disease and related dementia (AD) prevalence, incidence, treatment, and mortality, individuals from disadvantaged backgrounds (e.g. racial/ethnic minorities and socioeconomically disadvantaged persons) are under-represented in clinical research. Existing research recruitment approaches are rarely designed to accommodate the priorities, concerns, and constraints relevant to participants from diverse backgrounds. To address these gaps, the investigators developed a research recruitment and engagement model, the Participant Oriented Research Engagement Model that centers and prioritizes relational aspects of research engagement, research participant needs, and systematically address socioeconomic determinants (i.e. unmet needs) that may limit accessibility of research. The investigators propose to test the effectiveness of the Brain Health Community (BHC) Registry recruitment and engagement intervention, as compared to standard research recruitment strategies in modifying enrollment rates, participant satisfaction, and engagement. The investigators hypothesize that the BHC Registry will yield greater enrollment rates, higher satisfaction, and better ratings of relational engagement.

Home-based Family Caregiver-delivered Music and Reading Interventions for People With Dementia

DementiaDementia8 more

This international study evaluates the impact of home-based caregiver-delivered music and reading interventions for people with dementia. The project aims to address the need for improved informal dementia care by training family caregivers to utilise a music or reading intervention with the person they are caring for. The interventions aim to decrease behavioural and psychological symptoms of dementia as well as improve quality of life and well being of both people living with dementia and their caregivers. Participants will be allocated into a music intervention group, a reading intervention group or standard care group. In addition, the researchers will seek to determine the cost-effectiveness of using the music intervention.
