Filter by:This study will evaluate a new form of non-invasive deep brain therapy for individuals with Alzheimer's disease. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The trial will evaluate brain target engagement using magnetic resonance imaging, PET imaging, and numerical scales of cognitive performance.
The intervention being tested, CONFIDENCE-AI is a refined version of the original CONFIDENCE intervention made to reduce psychological financial strain and improve management of out-of-pocket care costs while increasing caregiver resourcefulness skills. Participants will be asked to participate in a 4-week intervention that includes participation in four, synchronous group-based Zoom sessions as well as between-session activities to apply learning. Participants will also receive tailored text message notifications from the NeuViCare AI-powered app via text and will be able to submit questions to the app to receive financial well-being information related to caregiving.
This study involves a brain positron emission tomography (PET) scan with a new, investigational radioactive tracer called [11C]-CS1P1 to identify inflammation in the brain by testing with healthy older adults and with cognitively impaired older adults.
This study is to evaluate the safety and tolerability of single dose of GB-5001 (donepezil) IM and SC depot in healthy male Adults. And, It is to evaluate pharmacokinetic characteristics of GB-5001 (donepezil) IM and SC single dose injection vs. active comparator.
This is a Phase 3, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of KarXT in male and female subjects who are aged 55 to 90 years and have mild to severe Alzheimer's Disease (AD) with moderate to severe psychosis related to AD. The primary objective of the study is to evaluate the efficacy of KarXT compared with placebo in the treatment of subjects with psychosis associated with AD as measured by the Neuropsychiatric Inventory-Clinician (NPI-C): Hallucinations and Delusions (H+D) score.
Xanamem® is being developed as a potential treatment for symptomatic, early stages of Alzheimer's Disease (AD) and Major Depressive Disorder (MDD). This XanaMIA Phase 2b study is to investigate the safety, tolerability, and efficacy of Xanamem in in mild or moderate dementia due to AD. Trial participants will be randomized to either receive 10mg of Xanamem once daily or a placebo for 36 weeks at a 1:1 ratio in a double-blinded fashion.
The diagnosis of diseases causing memory difficulties or dementia is often challenging. Without the use of advanced methods such as cerebrospinal fluid tests, approximately 25-30% do not receive a correct diagnosis today. However, the investigators have recently developed new blood biomarkers with high diagnostic accuracy, and the investigators now want to investigate whether they can eventually replace cerebrospinal fluid tests. This is because blood tests are much more cost-effective and significantly easier for patients compared to cerebrospinal fluid tests. In this study, 1200 patients undergoing clinical evaluations at the Memory Clinic, Skåne University Hospital in Malmö, are included for blood and cerebrospinal fluid sample collection. The blood samples are sent for analysis using the new blood biomarkers. Subsequently, the results are compared with those from the clinical analysis of cerebrospinal fluid to determine how well they perform in routine clinical practice as an alternative to cerebrospinal fluid tests and whether the blood test improves patient care. This comparison is carried out by the attending physician in three steps: 1. Assessment without access to the results of either the blood test or cerebrospinal fluid test. 2. Assessment with access to only the results of the blood test. 3. Assessment with access to the results of both the blood test and cerebrospinal fluid test. Aim 1) To prospectively validate plasma Alzheimer's disease (AD) biomarkers for diagnosis of patients with cognitive symptoms who are evaluated in a specialist memory clinic. Aim 2) Determine whether blood AD biomarkers improve patient management in specialist memory clinic settings.
Objective 1: To scale-up the nutrition adherence intervention for testing in predominantly Black and African-American rural communities in North Florida. The investigators hypothesize that: 1. The protocol will produce at least 75% of participants obtaining measurable levels of urine ketones (e.g., good adherence) in the Mediterranean-Ketogenic nutrition (MKN) group and an average score of >9 on the MEDAS questionnaire in the Mediterranean group during the 10-week program. Objective 2: To evaluate the effects of adherence to Mediterranean versus Mediterranean-Ketogenic nutrition on novel gut-brain axis markers of Alzheimer's disease pathogenesis in individuals with mild cognitive impairment compared to cognitively normal older adults. The investigators hypothesize that individuals with mild cognitive impairment will: 1. Have greater evidence of gut dysbiosis at baseline than cognitively normal controls and 2. Will demonstrate greater increases in beneficial gut microbial metabolites in response to adherence to Mediterranean-Ketogenic nutrition and the Mediterranean diet compared to CN controls.
This research study aims to examine biomarkers of Alzheimer's disease (AD) as early as possible which could potentially be a screening tool for the general population. This observational study will take place at the Skåne University Hospital in Sweden. The study will enroll up to 600 cognitively healthy subjects aged 50 to 80 years with 3/4 having preclinical Alzheimer's disease. Recruitment and enrollment will be ongoing for 2-3 years, and subject participation will be lasting approximately 4 years. Disclosure of AD risk assessments will be an optional procedure.
The overall aim of the study is to improve the diagnostic accuracy of AD and cognitive impairment in primary care settings to ensure better care and treatment as well as facilitate correct referrals to specialized memory clinics. The investigators will strive to recruit diverse and representative populations of patients with subjective cognitive decline (SCD), mild cognitive impairment (MCI) and mild dementia. The specific aims of the study are to: 1. Improve the detection of mild cognitive impairment (MCI) and dementia in primary care. 2. Develop and evaluate cognitive tests, blood-based biomarkers and brain imaging methods that are suitable for accurate and early diagnosis of Alzheimer's disease (AD) in primary care. 3. To prospectively validate plasma AD biomarkers for diagnosis of patients with cognitive symptoms who are evaluated in primary care. 4. Determine whether blood AD biomarkers improve patient management in primary care.
