NCT01202994
Alzheimer's disease (AD) is the most common cause of progressive cognitive decline in the United States. AD is characterized by severe impairments in learning, memory and other cognitive abilities that significantly interfere with daily functioning. The neuropathologic hallmarks of AD consist of neuritic plaques, neurofibrillary tangles, and selective neuronal cell loss. Amyloid plaques, which contain Abeta protein, are believed to play an integral role in the development of AD. Elevated levels of Abeta in the brain are also correlated with cognitive decline. Alzheimer's (AD) develops insidiously, making it difficult to identify early, yet treatment is most effective when begun during the early stages of the disease. Thus, it has become important for researchers to identify markers of early AD. This project will examine the relationship between four potential markers that may indicate the early development of AD: 1. Mild cognitive impairment (MCI)or normal cognition 2. Practice effects 3. Amyloid plaque binding on 18F-PIB PET 4. Glucose hypometabolism on FDG PET This project will recruit 25 subjects from an ongoing community-based study of memory and practice effects in cognitively normal, community-dwelling individuals who are age 65 and over (NIA #5K23AG028417-05). Each subject will undergo positron emission tomography (PET) with both 18F-Flutemetamol and FDG. The overall objective of this companion project is to study the biodistribution and binding of 18F-Flutemetamol in these subjects using PET imaging, which will provide biological evidence to support the overall hypothesis that failure to benefit from practice on a learning paradigm is an early marker of AD.
NCT05845736
Neurocognitive disorders and hypertension occur commonly with aging. While, by definition, older adults are at high cardiovascular risk, there is no guideline exist currently on blood pressure management of elderly hypertension. However, studies have shown that in aging adults, high blood pressure helps prevent against cognitive decline, and low blood pressure on antihypertensive drugs could accelerate it. This study aims at investigating if pharmacological treatment of hypertension in the very elderly is influenced by presence and severity of neurocognitive disorders. Our research hypothesis is that the drug management of hypertension in patients 80 years of age or older more is all the less aggressive as the neurocognitive disorders are advanced.
NCT04588649
Stroke can lead to signficiant neurological deficits, and about one-third of stroke patients will be diagnosed of vascular mild cognitive impairment or post-stroke dementia. Post-stroke dementia includes all types of dementia that happen after stroke, irrespective of their cause, and vascular dementia (VaD), degenerative dementia (especially Alzheimer's disease), or mixed dementia (dementia as a result of the coexistence of vascular lesions of the brain and neurodegenerative lesions) are the most common causes of post-stroke dementia. However, it is difficult to determine to what extent cognitive impairment may be attributable to stroke versus concomitant Alzheimer disease. With the advent of PET imaging technique, we are able to conduct a multi-modal neuroimaging study to explore the composite influence of vascular injury, amyloid plaque and Tau protein the the cognitive performance after stroke.

There are 3 periods in this study: Screening to confirm suitability, Treatment to receive study medication, and Follow-up to check overall health post-participation
NCT00811122
Alzheimer's disease (AD) is characterized by neuritic plaques, neurofibrillary tangles, and neuronal cell loss. Amyloid plaques are believed to play an integral role in AD. Elevated levels of Aβ in the brain are correlated with cognitive decline. There are no approved ways to measure amyloid load in humans. Several compounds are under investigation. All of these compounds use radioactive chemical tags for positron emission tomography (PET) imaging. The most promising compound is 11C-PIB, or Pittsburgh Compound-B. This compound can be injected and a PET scan performed. This allows doctors to see the amyloid plaques in the brain, and to use this information to look at other types of dementia to see if there are differences and/or similarities in the plaques. We will recruit a total of 30 subjects, 10 from each of the following three diagnostic categories: frontotemporal dementia (FTD), Alzheimer's disease, and normal volunteers. All subjects will be given an \[18F\]fluorodeoxyglucose or FDG-PET scan (if they haven't had one in the past) and a PIB-PET scan. The overall objective of this project is to study the biodistribution of 11C-PIB using PET imaging in normal elderly volunteers and relevant patient groups.
NCT02778971
The main purpose of this study is to explore the impact of an amyloid positron emission tomography and computed tomography (PET/CT) scan on physician diagnosis and management, including drug management and care practices, for patients with a diagnosis of cognitive impairment. This study also intends to capture specific patient-reported outcomes related to patient burden, confidence and satisfaction. The hypothesis is that to aid early diagnosis, individuals with a diagnostically uncertain etiology for their dementia will benefit from knowledge of amyloid plaque burden status, through an alteration of patient diagnosis and management, which will lead to significant changes in patient and care partner reported outcomes.
NCT05821153
Neuroinflammation is a significant component of Alzheimer disease (AD). Our data demonstrated compromised regulatory T cells (Tregs) phenotype and suppressive function in AD patients, skewing the immune system toward a proinflammatory status and potentially contributing in disease progression. Low dose interleukin-2 (IL-2) is now viewed as a very promising immunoregulatory drug having the capacity to selectively expand and restore functional Tregs. This study is a phase I open-label study to assess subcutaneous interleukin-2 (IL2) safety and potential efficacy as a Treg inducer in AD. 8 Alzheimer dementia patients with mild clinical dementia will be recruited into the study. The baseline cognitive status will be evaluated in these patients. Monthly five-day-courses of subcutaneous IL2 (1MUI/day) will be administered for a total of 4 months. Changes in Tregs from pre to post injections will be measured during the study period. The expected time participants will be in the study is 6 months.

NCT05814276
The goals of this clinical trial are 1) to estimate the number of professional caregivers and the time spent to carry out the non-pharmacological therapies for people with dementia and 2) to evaluate differences between professional caregivers trained and non-trained to non-pharmacological therapies for people with dementia in term of caregivers' burnout and well-being of people with dementia living in nursing home. The main questions it aims to answer are: * How long does it take professional caregivers to implement and carry out non-pharmacological therapies? * How many caregivers are needed to start and carry out non-pharmacological therapies? * Do the non-pharmacological therapies improve the quality of life of people with dementia? * Do the non-pharmacological therapies reduce behavioral and psychological symptoms of dementia? * Do the non-pharmacological therapies improve professional caregiver burnout, sense of competence and ethical climate in nursing home? * Do the non-pharmacological therapies reduce family caregivers' stress? Participants will attend ten sessions: * five theoretical meetings on dementia and non-pharmacological therapies; * five supervision meetings on the methodology for implementing non-pharmacological therapies based on discussions of cases. The investigators will compare the experimental group with an usual care control group to see if there are improvements in term of the quality of life of the resident perceived by the team, professional caregivers burnout, sense of competence of the carers and the ethical climate at the workplace.

NCT04276610
Age-related vision impairment and dementia both become more prevalent with increasing age. Research into the mechanisms of these conditions has proposed that some of their causes (e.g., macular degeneration/glaucoma and Alzheimer's disease) could be symptoms of an underlying common cause, or may be equally linked to a multifactorial context in frailty and aging. Research into sensory-cognitive aging has provided preliminary data that sensory decline may be linked to the progression of dementia through the concept of sensory deprivation. Preliminary data in hearing loss rehabilitation support the idea that improved hearing may have a beneficial effect on cognitive functioning; however, there are to date no data available to examine whether low vision rehabilitation, specifically for reading, could have an equally protective or beneficial effect on cognitive health. The present proposal aims to fill this gap.

NCT05785156
A large series of recent studies have documented the frequency of the slowing of the action in brain diseases, especially vascular and neurodegenerative diseases. In stroke, the predictive value of action slowing at the acute phase for predicting post-stroke functional outcome remains poorly investigated. In neurodegenerative diseases, the diagnostic relevance of the slowing at the prodromal stage remains unknown and this diagnostic requires new tests. Finally, in terms of anatomical determinants, few studies have studied the determinants of action slowing. The objectives of this project are to Determine the diagnostic and prognostic value of action slowing assessed with new quick tests in patients with acute stroke (Neurovascular Unit) and cognitive neurodegenerative disorders (Alzheimer Disease (AD), Lewy Body disease (LBD), Fronto Temporal lobar degeneration (FTLD), Cortico Basal Degeneration (CBD) and Progressive Supra Nuclear Palsy (PSNP)) and to define the lesion determinants with VBM and VLSM
