Background: About 5 million adults in the United States have age-related brain disorders. These include Alzheimer disease (AD), mild cognitive impairment (MCI), and other dementias. The number of people with these disorders will likely increase as the population ages and life span increases. Inflammation is thought to play a role in AD and MCI. Researchers want to know if an enzyme called PDE4B increases inflammation in people with AD or MCI. Objective: To test whether medical imaging using a new radiotracer (\[18F\]PF-06445974) can measure PDE4B in the brains of people with AD or MCI. Eligibility: People aged 50 years and older with AD or MCI. Healthy volunteers are also needed. Design: Participants will have up to 5 clinic visits with 3 imaging scans of the brain. They will have be screened. They will have a physical exam with blood tests. This will include tests of their heart and nerve function, including memory. Participants will have 2 positron emission tomography (PET) scans. One will use a standard radiotracer. The other will use the study radiotracer. They will receive each tracer through a tube attached to a needle inserted into a vein. During the scan with the study tracer, participants will have a second tube inserted into a vein in the wrist; this tube will be used to draw blood during the scan. Participants will lie on a bed that slides into a doughnut-shaped machine. These visits will take about 6 hours each. Participants will have 1 magnetic resonance imaging (MRI) scan. They will lie on a bed that slides into a cylinder. This visit will take up to 2 hours....
Bio-Hermes-002 is a 120-day cross-sectional study that will result in a blood, CSF, retinal, digital, MRI, and PET brain imaging biomarker database that can be used to determine the primary objective. Digital biomarkers and blood-based biomarkers will be tested to determine whether a meaningful relationship exists between biomarkers alone or in combination with tau or amyloid brain pathology identified through PET images.
The purpose of this study is to evaluate the effect of atorvastatin on brain vessel reactivity and with it on blood flow in people with mild cognitive impairment.
This study compares different music therapy (MT) experiences and their impact on memory and language in patients with Alzheimer's disease and Mild Cognitive Impairment. The 12-month study will assess the role of common experiences involving familiar music and other pleasant events (blinded control) to benefit cognition and measure the quality of life for people with Alzheimer's disease and Mild Cognitive Impairment. Following screening, all participants will meet with a licensed music therapist at the first study visit. Thereafter, each group will have an individualized schedule of follow-up telephone calls and visits. Screening for the study and participation in the study intervention can be completed in-person or from your home, if you do not live in the area.
The goal of this observational study is to evaluate the functionality and usability of Indivi mobile application-based cognitive activities in people with mild cognitive impairment/mild Alzheimer's disease (PwMCI/AD) and healthy controls (HC). This application uses a dynamic difficulty adjustment (DDA) system that customizes the level of the cognitive activities to each user. The main questions it aims to answer are: * Does the DDA system reach a stable difficulty level at the same rate for both PwMCI/AD and HC? * Is the stable difficulty level reached by the DDA system different for PwMCI/AD compared to HC? Researchers will also compare cognitive activities results and other aspects of the mobile application's performance to see if the application can validly distinguish between the two groups. Participants will use the Indivi mobile application, with its embedded DDA system, for a 6-week period.
The Memory Support System (MSS) from the Healthy Action to Benefit Independence \& Thinking® (HABIT) Program is an evidence-based, non-pharmacological intervention for mild cognitive impairment (MCI). Despite the clinical benefits and feasibility, the MSS was primarily developed and used with non-Hispanic White, English-speaking adults. Racial/ethnic minority groups are chronically under-enrolled in clinical trials for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD) due to lack of linguistically and culturally appropriate adaptation of assessment measures and intervention protocols. The purpose of this research study is to examine whether the MSS from HABIT can help Chinese American older adults with mild thinking and memory problems. Target recruitment is 60 Chinese American adults who are primarily Mandarin- (n=30) and Cantonese-speaking (n=30). Forty participants will participate in the trainer-led day planner training and 20 will participate in self-study of the day planner and receive brain health education. Each participant will also be asked to identify a study partner to participate with them.
Older adults with Mild Cognitive Impairment (MCI) often show less brain activity in a specific range (8-13 Hz, known as alpha power) compared to healthy older adults. Those with lower alpha activity, especially in the front part of the brain, usually have problems with executive functions like planning and multitasking. Our research has shown that older adults with lower alpha power in these areas also struggle more with balance when they have to do two things at once (like standing and performing a cognitive task simultaneously). The investigators believe that increasing alpha power in older adults with MCI could improve their balance and executive function, helping them stay independent longer. In early studies, the investigators found that using transcranial alternating current stimulation (tACS) at 10 Hz on the front part of the brain can boost alpha power and balance immediately after a single session in older adults with MCI. The effect was stronger in those whose natural brain activity was close to the 10 Hz stimulation. Based on these findings, the investigators plan to conduct a pilot study with older adults aged 65-85 years with MCI. Participants will be randomly assigned to receive either real tACS or a sham (placebo) treatment. Our main hypothesis is that real tACS will improve balance when multitasking, and these improvements will last for 1 to 3 months after the treatment. The investigators also believe that tACS will enhance other aspects of executive function and mobility and that these improvements will be linked to increased alpha activity in the brain. Through this study, we aim to gather strong evidence that tailored tACS is a promising treatment to improve cognitive and motor functions and overall brain activity in older adults with MCI.
The goal is to assess the accuracy of an application that analyzes voice characteristics to diagnose patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). The main question is whether the application's diagnosis is the same as the clinician's for MCI and AD patients.
The goal of this pilot clinical trial is to learn if older adults with mild cognitive impairment (MCI) find two music programs equally acceptable. This pilot study will help researchers prepare for a future, large-scale clinical trial to learn if music training can slow cognitive decline and promote emotional well-being in those at risk for Alzheimer's disease and related dementias. The main questions this pilot study aims to answer are: * Do participants like the music programs? * Do participants stay enrolled in the study? * Do participants report perceived benefits of the programs for their emotional well-being or everyday memory? Participants will: * Participate in 12-weekly sessions of piano lessons or music lessons, with group and individual lessons alternating each week. * Have home practice in between lessons, with a keyboard or other instruments provided. * Keep a diary of their home practice and their mood before and after practice. * Participate in interviews before and after the 12-week programs.
Mild Cognitive Impairment (MCI) in older adults is linked to muscle loss (sarcopenia) and can lead to dementia, with pain further impacting cognitive and physical performance. Tai Chi, a mind-body exercise, is recommended for managing MCI as it supports cognitive function, mood, and physical health. The investigators' first goal is to characterize the correlation of heart rate variability and cortical activity on cognitive function and the psychosocial correlates of pain interference and social isolation on cognitive function at baseline and post-intervention (8 weeks of Tai Chi). The second goal is to explain the role of sarcopenia and obesity in the relationship between pain interference and cognitive function. The investigators also want to examine the index of the predictive capacity regarding sarcopenia and obesity on cognitive function outcomes.
