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.
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 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.
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 randomized clinical trial is to compare the efficacy of the use of a diary to record behavioral and psychological symptoms of dementia (BPSD) in persons with dementia. The main questions it aims to answer are: - Does the use of a diary lead to a reduction of the caregiver's burden at 3 months, compared with standard care? - Does the use of a diary lead to a reduction of the neuropsychiatric inventory (NPI) score at 3 months, compared with standard care? - Does the use of a diary result in less psychotropic drugs prescribed to the patient at 3 months compared with standard care? - Are physicians and caregivers satisfied with managing patients with the use of a diary? - Does the use of a diary reduce the caregiver's stress related to BPSD at 3 months, compared with standard care? Participants will be randomly assigned to either the use of a diary or a control group. Caregivers in the diary arm will be asked to fill in a diary with BPSD including triggers, severity, day and hour, to be analyzed by physicians to prescribe appropriate pharmacological or non-pharmacological interventions. The control group will receive usual care (i.e., appropriate interventions will be applied after interviewing the caregiver and/or visiting the patient).
The CIRCAME study is a bicentric study of patients from 2 memory clinics in Paris. The main objective is to identify circadian rhythm components and other individual risk factors (sociodemographic, behavioral, and health related factors) associated with the diagnosis of subtypes (AD, Lewy bodies, vascular, frontotemporal dementia) and stages (cognitively healthy, mild cognitive impairment, clinical dementia) of dementia, independent of known risk factors (sociodemographic and genetic) and assess the relevance of use of these factors in primary care for screen of dementia including subtypes and stages. A secondary objective is to determine factors associated with progression of the disease, in terms of cognitive decline and limitations in activities of daily living, as well as progression to dementia among cognitively healthy controls and patients with mild cognitive impairment, up to 15 years after the inclusion period.
This project aims to explore the feasibility and effects of a symptom-specific, brain-circuit-based, home-based neuromodulation therapy for addressing mood and memory symptoms in older adults with major depressive disorder (MDD) in the context of dementia.
The purpose of this study is to compare patient priorities care (PPC) and usual care (UC) patients to identify differences in post-encounter medication changes, treatment burden (TBQ), and shared decision making in Older Patient Assessment of Chronic Illness Care (OPACIC), to understand PPC participant's sense-making and communication approaches related to deprescribing decisions in relation to the identified health priorities and to identify and categorize adverse drug withdrawal events (ADWEs)
Scalp to cortex distance (SCD), as a key technological parameter of brain stimulation, has been highlighted in the guidelines of non-invasive brain stimulation. However, in the context of age-related brain changes, the region-specific SCD and its impact on stimulation-induced electric field in different types of neurodegenerative diseases remain unclear.
