Active clinical trials for "Alzheimer Disease"

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.

The purpose of this study is to identify association between cerebrospinal fluid Alzheimer's Disease's neurodegenerescence biomarkers (tau, ptau, Aß40 and Aß1-42) and occurrence of cognitive deficits in older patients with bipolar disorders.

Alzheimer's Disease is a neurodegenerative disease age related caused by neurofibrillary tangles misfolding and Beta-amyloid protein accumulation. In the last decade several findings showed the role of biophenols present in diary intake such as extra virgin olive oil as potential antagonist of neurodegeneration. Two population studies (The Seven Countries Study and Three-City-Study) and four clinical trials (PREDIMED, PREDIMED - NAVARRA, ACTRIN and ISRCTN) have already suggested that mediterranean diet or other diets supplemented with extra virgin olive oil could improve cerebral performance.

Along with population ageing, the association of chronic conditions such as Alzheimer's Disease and Related Syndromes (ADRS) and diabetes mellitus is increasing in clinical practice. According to ADRS severity, guidelines of diabetes care may be adapted for a personalized monitoring and treatment. The consequences on diabetes complications are not known and can also threaten dementia progression. Based on a nationwide healthcare reimbursement database, the present study aimed to compare diabetes care and the incidence of acute complications between patients with or without ADRS, in a longitudinal perspective focusing on the pivotal period of ADRS identification by the healthcare system.

Alzheimer disease (AD) is a neurodegenerative disorder with a poorly understood pathology. It is an irreversible progressive brain disease that slowly deteriorates memory, thinking and behavior. It affects the elderly population and is also hereditary. The incidence doubles with every decade after sixty with no signs of leveling off. More than 35 million people Worldwide, including 5.5 million living in the United States, suffer from AD. As the United States population ages, it is expected that the number of people with AD will increase, reaching 13.2 to 16.0 million by the year 2050. The cost of care for patients with AD in the United States is expected to rise as well, from $172 billion a year in 2010 to a trillion dollars a year by 2050. Although the exact etiopathology is not known there are several lines of evidence that suggest that metabolic and inflammatory features are important. It also has been known for many years that the Blood Brain Barrier (BBB) of Alzheimer's patients allow more harmful particles to cross into the brain than the BBBs of those without the disease do. It's known that this barrier, which is regulating transfer of molecules between the brain and blood, and vice versa blood and brain, can become leaky and dysfunctional (in particular capillaries dysfunction) and lead to subsequent problems likely contributing to onset and progression of dementia. This protocol will explore several of the most promising putative factors that cause AD.

Initiatives have been taken hotline in France and abroad for other conditions, they provide support to patients and their caregivers.

Prospective study on patients enrolled in the ReCODE treatment protocol

This study attempts to replicate the findings published in Nature Medicine by Nation and colleagues (2019). By using a large observational cohort (DZNE - Longitudinal Cognitive Impairment and Dementia Study; DELCODE) consisting of cognitively healthy individuals, individuals with subjective cognitive decline, mild cognitive impairment, and dementia due to Alzheimer's disease, an association between the blood-brain barrier and cognitive dysfunction is investigated. The integrity of the blood-brain barrier is investigated by using a novel MRI protocol as well as a novel biomarker in the cerebrospinal fluid.

Dementia; It is a chronic syndrome characterized by a general and progressive deterioration in cognition, including memory, orientation, language, and comprehension. The prognosis of this progressive and neurodegenerative disease after diagnosis may differ between individuals. In its broadest sense, the prognosis after a diagnosis of dementia; can be defined by shortening of life span, high level of cognitive and functional loss, decrease in quality of life and increased need for care. However, the prognosis of different types of dementia is highly variable. Because it is the most common type of dementia, studies are usually on Alzheimer's disease. It constitutes 50-75% of total dementia cases. Vascular dementia is the second most common cause of dementia and accounts for approximately 15% of dementia cases. Dementia with Lewy bodies constitutes 10-20% of the total dementia patients and ranks second among degenerative dementia types. Frontotemporal dementia, which mimics psychiatric disorders and has prominent behavioural problems, and Parkinson's disease-associated dementia, which is characterized by cognitive impairment that can be added to the existing picture in Parkinson's patients, are also counted among other types of dementia. Prognosis-related data on dementia types other than Alzheimer's disease are limited in the literature. Determining the prognosis is important to support patients, anticipate long-term health problems, plan physician and healthcare provision, and support patients with dementia.In view of the lack of sufficient data on dementia types other than Alzheimer's disease, it is aimed to contribute to the literature on this subject and to determine the factors that may affect prognosis, morbidity and mortality in patients belonging to all dementia types.

The Infinitome Program from Omniscient has the ability to identify abnormal brain networks or connectomes using resting state functional MRI (rs-fMRI). This technology, which visualizes brain networks in three dimensions, was originally developed to ensure neurosurgeons avoid inadvertently lesioning cognitively eloquent brain regions during surgical operations. The potential of Infinitome in identifying connectome dysfunction for neurodegenerative diseases such as Alzheimer's disease has yet to be explored. This diagnostic technique may play a critical role for identifying disease brain networks that may benefit from targeted interventions in clinical trials.
