Active clinical trials for "Alzheimer Disease"

The purpose of this study is to determine whether the anti-inflammatory drug celecoxib can delay the onset of Alzheimer Disease (AD) in people with Age Associated Memory Impairment (AAMI). This study will also evaluate genetic risk and brain structure as potential predictors of mental decline.

This study is a prospective observational study, which involves a cohort of 2000 all-sex and all-ethnic people aged 60 years and above with permanent residence in Tianma area, SheMountain Town, Songjiang District (suburban area), Shanghai. Demographic information, neuropsychiatric scale, peripheral blood, APOE genotype, brain MRI, speech information, AV45-PET, FDG-PET, Tau-PET, GLP-1R PET, and cholinergic receptor probe (ASEM) PET were collected and analyzed. Follow-up visits were performed twice a year for 4 visits, and neuropsychiatric scales and biological samples were collected at each follow-up visit to construct a diagnostic model for patients with mild cognitive impairment, or Alzheimer's disease, as well as a predictive model for the progression of cognitive impairment.

Tests will be performed in individuals with Alzheimer's dementia to compare dual-task and gait with healthy geriatric individuals.

In France, an estimated 860 000 patients are affected by Alzheimer Disease (AD) which represents, as in other developed countries, a major public health issue. In many cases, AD diagnosis is uncertain and its clinical evolution unpredictable. The exactitude of the diagnosis is however particularly important in the perspective of the validation and use of new therapeutic strategies in AD. Detection of cerebrospinal fluid (CSF) diagnosis biomarkers fell short in the detection, of atypical/mixed cases, of some differential diagnosis, and in differentiating rapid or slow clinical evolutions. Hence, CSF analysis gives a unique opportunity to detect and validate biomarkers in many neurological disorders. Nevertheless, in medical practice, CSF biological analysis is currently limited to a small number of analytes.Quantitative and targeted mass spectrometry, especially operated in the Multiple reaction monitoring mode (MRM), represents an alternative to immunodetection and could be used to detect specific biomarkers in complex matrices such as plasma by specifically discriminating the proteotypic peptides corresponding to each proteins. Mass spectrometry has also the ability to distinguish and quantify isotopically labelled and unlabeled selected targets. This ability was used in a publication by the group of R. Bateman (Washington University, St Louis, USA) who could, after administering stable isotope-labelled leucine, evaluate Ab synthesis and clearance in humans. This approach has an enormous potential to study the metabolism of proteins within the human CNS and consequently help in the understanding and diagnosis of neurological disorders.The main objective of this program is set up a targeted quantitative mass spectrometry method for existing and stable isotope-labelled CSF biomarkers in the neurological field; exploit this approach for diagnostic purpurses and to gain knowledge in the pathophysiology of diseases.

The role of disorders of socio-emotional processes in cerebral diseases such as Alzheimer's disease, frontal temporal dementia, Parkinson's disease, Huntington's disease, traumatic brain injury, stroke, focal lesions, has been recognized recently. Social cognition refers to a large group of emotional and cognitive abilities regulating inter-individuals relationships and it includes mainly theory of mind, emotional information processing and empathy. However, assessment of socio-emotional processes is still largely based on experimental tests that are not validated for clinical purpose. In addition their long duration of administration is not adapted to clinical examination. Finally these tests have not been standardized and normalized in French-speaking population.

This study is being done to learn about tau tangles in Alzheimer's disease. A type of PET scan is used to measure the abnormal accumulation of protein called tau in the brain. These are thought to be involved in Alzheimer's disease. The investigators will also perform brain MRI and to tests to measure the participant's memory and thinking.

The primary purpose of this study is to identify participants with or without symptoms of Alzheimer's Disease (AD) that are at high risk for brain amyloid pathology using blood-based biomarkers.

IONA LCS is a research project that will allow the testing of multiple new therapies as well as diagnostic tests for neurodegenerative diseases. IONA LCS acts primarily as a readiness cohort for interventional studies targeting the treatment of neurodegenerative disease but also provides data as the reference standard to validate new diagnostic tests. As such, it is a foundational element to support a range of research projects undertaken by Scottish Brain Sciences and our partners.

This project's main goal is to use state-of-the-art passive sensing techniques to identify digital biomarkers that relate to bioenergetic changes in the brain due to nicotinamide riboside supplementation in those with mild cognitive impairment and mild Alzheimer's dementia.

To determine if low level magnetic fields can help to improve memory in patients diagnosed with Alzheimer's disease.
