Active clinical trials for "Alzheimer Disease"

The objectives of this project are to examine amyloid burden and cognition in a group of subjects diagnosed with Alzheimer's Disease (AD) or Mild Cognitive Impairment (MCI) before and after a six month course of insulin delivered weekly in a controlled pulsatile intravenous fashion in a clinical setting. The investigators central hypothesis is straightforward: The investigators predict that controlled pulsed IV infusion of insulin will improve cognition in patients with AD, and that this improvement will be correlated with a decrease in amyloid burden in these patients.

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.

The main objective of this study is to assess whether Periodontal Disease is more prevalent in adult patients diagnosed with Alzheimer's Disease compared to adult patients without Alzheimer's Disease. The secondary objective is to describe and characterize the microbiological and biochemical profile of adult patients diagnosed with Alzheimer's Disease and compare with adult patients without Alzheimer's Disease.

Damages in frontal area present in neurodegenerative disease (frontotemporal degeneration, frontal variant of Alzheimer disease) and in psychiatric disease (bipolar disorder) can affect behavior and cognition including social cognition. Symptoms vary both quantitatively and qualitatively from disease to another and from person to person. It cannot be completely excluded that in some cases, factors of susceptibility such as premorbid personality traits lead to frontal fragility. The study will assess the relationship between premorbid profile using NEO-PI 3 inventory and cognitive and behavioral/psychobehavioral manifestations in patients with behavioral variant of frontotemporal disorder (bvFTD), phenocopy frontotemporal dementia (phFTD), frontal variant of Alzheimer disease, bipolar disorder characterized with frontal damages.

The physio-pathology of Alzheimer's disease (AD) remains unknown and there is no cure. Thus, the search for objective markers of preclinical first signs of cognitive impairment, is currently a major public health issue. Early detection of the disease is a major challenge to hope to slow or even stop the neurodegenerative process before the stage of dementia. In AD the investigators observe: A reduction in the volume of brain hippocampi associated with an alteration of the diffusion of water molecules in the white matter. A structural brain degeneration coupled with a decrease in cerebral glucose metabolism. Recent publications show that cerebrospinal fluid (CSF)flow is also altered, probably due to dysfunction of the choroid plexus. Hence the potential interest to study is, in addition to conventional imaging, the imaging of CSF dynamics and choroid plexus metabolism. In that aim,the investigators use two imaging modalities: Magnetic resonance imaging (MRI) is used to assess blood and CSF flow in the brain Positron emission tomography (PET) is used to assess glucose metabolism in grey/white matter and also in choroid plexus. The investigators expect that, because of choroid plexus atrophy in AD, CSF flow would be altered as well as glucose metabolism dynamic in choroid plexus.

Personalized Integrated Care Promoting Quality of Life for Elderly People (ProCare4Life, PC4L) project was created to finalize a digital platform with integrated sensors , for monitoring the health status of the elderly subjects with neurodegenerative diseases and comorbidities. In fact, an integrated care platform - able to establish correlations between comorbidities, investigate the intake of different drugs, mitigate potential health risks, study the social variables and promote unified therapeutic procedures or social services - could help patients, caregivers, healthcare professionals and social health workers to monitor various diseases parameters. The main contribution of the PC4L project is to propose an integrated, scalable and interactive care system that can be easily adapted to the reality of various chronic diseases, care institutions and end-user needs, for the benefit of all the actors involved. The main expected results are to improve patients' quality of life, enable an active life and better disease management, support professionals in decision making, facilitate efficient communication between all stakeholders and ensure reliable and secure access to data at the within Europe.

The purpose of this study is to evaluate the PK, safety, and tolerability of a new liquid formulation of tricaprilin.

The proposed research project aims to answer the question "Are immersive technology systems effective in the management and treatment of patients with BPSD?". This project is composed of three phases and the current study is the first phase. The phase 1 trial aims to create an immersive technology system for managing the behavioral and psychological symptoms of dementia and determine its acceptability, usability, and safety in the healthy adult population.

The 'Western diet' characterized by high fat feeding (HFF) is a risk factor for Alzheimer's disease (AD); however, little is known about mechanisms. Paradoxically, individuals who carry the AD risk gene APOE E4 cognitively improve after HFF and show different metabolic responses to fat intake. These responses include a more pronounced drop in systolic blood pressure and a decrease in cerebrospinal fluid glucose and lactate levels. This proposal will further examine the brain metabolic response to HFF using non-invasive imaging. Cerebral blood flow (CBF) as assessed by functional MRI is increasingly utilized to investigate brain function, given that CBF is tightly coupled to brain metabolism. Acute changes in CBF have been described in response to carbohydrate ingestion in regions important for learning and memory; however, no one has yet assessed CBF response to lipid. Here investigators propose to characterize CBF changes to a high fat drink in older adults. This study will include a time course assessment as well as analyses of global and regional change in CBF. These data would serve as feasibility pilot data for an R01 application which would include cognitive and peripheral metabolic data. These types of studies will provide a clearer picture of acute brain metabolic response to HFF in older adults, including the effects of APOE.

The purpose of this study is to test the psychoeducational program "Tele-Savvy." Tele-Savvy is an internet based, group education program developed from an in person program called Savvy Caregiver. Participants will be randomly assigned to either the Tele-Savvy group (receiving only the Tele-Savvy education) or the Healthy Living Education Program (receiving healthy lifestyle education and then Tele-Savvy education 6 months later) or a usual care group (receiving Tele-Savvy education 6 months later). Each program takes 43 days to complete.
