Filter by:In a society with increased life expectancy, the economic, social and personal burden of dementia increases. Dementia is often caused by a combination of neurovascular and neurodegenerative diseases. Impaired brain clearance is suggested to be closely related to dementia development, as waste products (e.g. amyloid beta) accumulate in the brain, leading to neurodegeneration. Cerebral small vessel disease (SVD) is the most common neurovascular disease that even contributes to about 45% of dementia pathophysiology in patients with a diagnosis of Alzheimer's dementia. White matter hyperintensities of presumed vascular origin (WMH) are the key brain MRI manifestation of cerebral SVD. There is evidence that the currently known and MRI-visible WMH are landmarks of an already progressed stage of the underlying pathology. The pathophysiology of WMH has been attributed to multiple underlying mechanisms, such as hypoperfusion, defective cerebrovascular reactivity and blood-brain barrier dysfunction. Furthermore, different anatomical locations and different types of WMH are related to different underlying pathological changes. Using ultra-high field 7T MR imaging techniques WMH lesions can be detected with a higher sensitivity and resolution than on 3T MRI. The hypothesis is that different pathological mechanisms of cerebral SVD lead to variations in WMH shape. Moreover, the brain clearance ('glymphatic') system of the brain appears to be tightly connected to dementia pathology. Thus, novel markers of glymphatic activity could aid to describe and understand the pathology.
Building upon the HEARS audiologist-community health worker (CHW) model, this study intervention will be delivered by a speech-language pathologist (SLP). The primary objective of the study is to develop and test an affordable and accessible hearing rehabilitative intervention that will be delivered by a SLP to individuals with cognitive impairment.
To observe the clinical efficacy of TCM acupuncture combined with western medicine nimodipine for prevention of post-stroke dementia by comparing with clinical conventional treatment methods.
The goal of this survey study is to identify environmental, occupational and reproductive health risk factors for Lewy body dementia, which includes Parkinson's disease dementia and dementia with Lewy bodies. Participants will complete a one-time survey online or over the phone that includes questions on environmental, occupational factors they may have been exposed to and on medical history including reproductive health. Researchers will then compare the responses of people with Lewy body dementia and people without Parkinson's or memory/thinking problems to see which factors play a role in Lewy body dementia. Identifying risk factors can guide future treatment efforts and provide more insight to this dementia.
The goal of this intervention study is to test whether the educational intervention work well or not on informal caregiver of person with dementia. The main question it aims to answer is does the educational intervention will help to reduce the caregiver burden experience by the informal caregiver. Participants will be given an educational module and short videos that they can refer to gain more knowledge and skills in caring for the person with dementia.
The goal of this pragmatic, embedded clinical trial is to analyze the implementation of Patient Priorities Care in primary care and geriatrics clinics with patients living with dementia or mild cognitive impairment. This study aims are: - demonstrate the feasibility of using the electronic health record to identify a diverse cohort of eligible patient and patient-care partner dyads who will engage in a Patient Priorities Care conversation with a trained facilitator. - demonstrate feasibility of pragmatically assessing clinical outcomes using the electronic health record, including a) number of days at home, b) total medications, and c) new referrals to specialist physicians. - examine key feasibility measures across racial, ethnic, and socioeconomic subgroups. Participants will receive a packet of information about Patient Priorities Care from their primary care clinic, in advance of their next upcoming clinic appointment. Individuals who receive a packet will have the opportunity to engage in a conversation about what matters most to them and what their priorities are, with trained facilitators at the clinic.
Depending on the YASAM project which was established to home-visit evaluate community-dwelling older adults (80 years of age and over), we aimed to determine the prevalence (prevalence) of geriatric syndromes (dependence, frailty, malnutrition, depression, dementia, comorbidity burden, polypharmacy) in these individuals and to determine possible changes in the follow-up of the patients during the 2-year follow-up period. (HEAVEN trial)
This study aims to pilot test a culturally tailored behavioral intervention called "WECARE" to enhance caregiving mastery and improve psychosocial wellbeing of Chinese American family caregivers of persons with Alzheimer's Disease and related dementia.
The purpose of this single arm study is to evaluate the feasibility and safety of treatments with a non-invasive neuromodulation device in adults diagnosed with mild/moderate Parkinson's disease dementia (PDD). A non-invasive device is a device that stays outside of the body and is not implanted and does not penetrate the skin. Neuromodulation means that the device stimulates activity in the brain.
The goal of this clinical trial is to test the feasibility of the Individualized Positive Psychosocial Interaction (IPPI) with 108 nursing home residents living with dementia and distress or depressive symptoms. The main questions it aims to answer are: •is it feasible to deliver the IPPI and track impact through data collected in the electronic medical records. Care partners will engage eligible residents in 2 brief preference-based IPPIs per week over the course of 6 months.
