This study seeks to translate a proven cognitive treatment for Spanish-speaking Hispanics with subjective memory/cognitive complaints or a diagnosis of mild cognitive impairment (MCI) and their care partners. MCI causes cognitive changes that are noticed by the individual or others. These changes do not significantly interfere with independence. MCI also increases the risk of developing Alzheimer's or another dementia, particularly in Hispanics/Latinos. There is no medication that improves cognition or delays MCI. However, providing cognitive treatment can alleviate the effects of MCI. Only a few cognitive interventions have been proven effective in the U.S., but none has been adapted to the Spanish-speaking Hispanic community. Our proposed cognitive treatment uses effective strategies (e.g., calendar and notetaking) to compensate for memory loss. The investigators will first follow international guidelines to ensure proper translation of our treatment into Spanish. Then, the investigators will pilot test our translated intervention in 20 Spanish-speaking Hispanic participants with subjective memory/cognitive complaints or a diagnosis of MCI and their care partners (40 participants total). The investigators will also assess the degree to which participants follow medical advice; their beliefs in their ability to succeed in and do daily activities, including managing medications; their feelings and potential burden associated with caregiving before and after the treatment as well as 8 weeks later. Results will allow the investigators to determine whether our treatment was effective and to calculate the number of participants required for larger studies. Overall, the study represents an important step to respond to the needs of the Hispanic community.
The three primary goals of this pilot will be followed by a secondary goal to test if dental intervention improves brain health in terms of sleep and cognition. The primary and secondary goals are 1. Explore the ratios of brain energy (ATP/PCr, Pi/PCr) and phospholipids (PME/PDE) metabolites as measured by magnetic resonance spectroscopy at 7 Tesla, and compare the differences in them with the performance of episodic memory, attention, language, and executive functions (abstraction, reasoning, verbal fluency, working memory) in three groups: cognitively normal adults, mild cognitive impairment (MCI) and Alzheimer's disease (AD). 2. Investigate the differences in sleep patterns measured by the ratio sleep quality index (Stable/ Unstable sleep) in cognitively normal adults, MCI and AD and its relation to the performance of episodic memory, attention, language, and executive functions (abstraction, reasoning, verbal fluency, working memory) in three groups. 3. Investigate the differences in the variations of two genes, APOE-E4 and ABCA7, in relationship to the changes in the brain energy metabolites and its relation to the performance of episodic memory, attention, language, and executive functions (abstraction, reasoning, verbal fluency, working memory) in those with cognitively normal adults, MCI and AD. 4. Investigate if dental intervention improves sleep patterns and overall cognitive behavior in the three cohorts.
The purpose of this study is to examine therapeutic efficacy of cognitive Training based on location information and activity in people with mild cognitive impairment
The aim of the study is to determine: (1) the effects of combined physical exercise and cognitive training versus exercise or cognitive training alone on cognition, physical function, daily function, quality of life and social participation outcomes, (2) determine the relative effects of simultaneous vs. sequential combination of physical exercise and cognitive training on these health-related outcomes, (3) determine the long-term effects of different types of trainings on these outcome measures.
This protocol is designed to assess the utility of a new positron emission tomography (PET) radiopharmaceutical to image tau, [18F] JNJ067, invented by Janssen Pharmaceutical companies of Johnson & Johnson. To date, the radiopharmaceutical has been used in a small group of patients and controls (<20). The study plans to expand the range and number of subjects, to examine a total of 18 participants including controls and patients with Alzheimer's disease (AD) and other dementias. All patients will be recruited from the University of California, San Francisco (UCSF) Memory and Aging Center (MAC) and controls will be recruited from the University of California, Berkeley Aging Cohort Study (BACS). Patients will undergo a multidisciplinary clinical evaluation for diagnosis and a cognitive assessment at the MAC; controls will undergo the usual BACS cognitive assessment performed on the Berkeley campus. Following these evaluations UCSF subjects will undergo magnetic resonance imaging (MRI) scanning at the UCSF Neuroimaging Center and blood sampling for genetic testing also at UCSF, and BACS subjects will undergo an MRI at the University of California Berkeley 3T Brain Imaging Center (in Li Ka Shing hall on the Berkeley campus) and blood sampling for genetic testing at the time of the PET scan. All subjects will come to Lawrence Berkeley National Law (LBNL) where they will have, on the same day, a C-11 Pittsburgh compound B (PIB) PET scan to measure brain amyloid, and an F-18 JNJ067 PET scan to measure brain tau. These scans will be examined and analyzed by LBNL staff, and data will be processed to examine basic questions about the quantitative behavior of JNJ067. Scan results will not be returned to control subjects, but physicians at UCSF will receive scan results on MAC patients and will share results with participants. As part of this protocol, the investigators also plan to share the acquired data widely. All data will be de-identified. Data will be shared with the inventors (Janssen/Johnson & Johnson) as well as other scientists worldwide. As this is a new radio tracer, the investigators anticipate that there will be interest in seeing the actual data to answer questions about uptake and application of the method in future studies in many different laboratories. Shared data will include PET scans, MRI scans, genetic testing, and neuropsychological results.
The aim of this study is the efficacy of a docosahexaenoic acid (DHA)-rich dietary supplement in improving key dementia-related mechanisms and cognitive function in older people at risk for dementia. This is a randomized placebo-controlled, 24 weeks, phase 2 study of Omega 3 in people with increased risk of dementia. The aim is to explore the effects of DHA on cognitive performance (CERAD 10 word memory tests, TMT A/B, Stroop Color-Word, FAS, VOSP silhouettes, Cantab-test (RT, PAL, SWT)), biological markers (blood: CRP, NLF, TNF-alpha, MCI-1, PBMC Abeta middomain, Omega-3-index, IL, CSF: NLF, sTREM2, Ab 1-42, total and -phospho-tau) and imaging (MRI: standard structural DDI protocol including Freesurfer and WML measurements, DTI and ASL).
This project aims to examine the effect of a 5-month period supervised exercise intervention on brain, cognition, OMICs, Molecular Markers and functional status in older people at risk of mild cognitive impairment. Secondarily, the effect of this intervention on antioxidant capacity, lipid metabolism and glucose, physical health (functional capacity, blood pressure, body composition) and mental (quality of life and depression) will be studied, as well as other factors risk (genetic and biological) for the development of Alzheimer. A total of 100 people aged between 65 and 75 years old at risk of mild cognitive impairment will be randomly distributed in the supervised exercise intervention group (n = 50) and control group (n = 50). The design will include a 5-month intervention with measurements at pre and post intervention and a third measurement (retest) after 3 months of completion. The multicomponent supervised exercise program will include aerobic, strength, cognitive and coordinative-agility-balance works, and progression will be established in different load parameters (frequency, volume, intensity, density). Therefore, randomized controlled studies are needed to know the specific effect of dose-response considering the various dimensions in parallel such as neuroimaging, cognitive status and OMICS. This will allow us to understand from a comprehensive perspective the causes and mechanisms underlying the response. This project will significantly increase scientific knowledge about the role of exercise on brain as a therapeutic measure in people at risk of mild cognitive impairment from a multidimensional perspective. The project will have a significant impact at social and economic level by transferring the study findings to social and health setting by means of agents and networks provided for the project.
This is a longitudinal, observational study evaluating the imaging characteristics of the tau PET radioligand [18F]MK-6240 in Alzheimer's disease (AD), Mild Cognitive Impairment (MCI) and Healthy Volunteer (HV) subjects. Up to 42 subjects, including approximately 28 MCI/mild AD subjects, up to 5 moderate AD subjects, and 9 similarly aged HV subjects will be consented and screened. Imaging procedures include [11C]PiB to evaluate amyloid deposition, [18F]MK-6240 PET, and structural MRI. All subjects complete an evaluable baseline [18F]MK-6240 PET scan, as well as scans at 6, 12 and 24 months post-baseline. If unable to complete the 6 month, 12 month, or 24 month visit, an 18 month and/or 30 month visit may instead be scheduled, totaling a maximum of four time points.
Loss of cognitive abilities leading to Alzheimer's disease is progressive and destructive, leaving older adults disabled and unable to recall their past. The number of older adults with Alzheimer's disease is expected to triple by the year 2050, yet little research examines amyloid beta deposition, executive function, and progression of disability. This study will test the influence of a novel and promising non-pharmacological intervention, Strategy Training, on the progression of disability in a sample of 150 older adults with Mild Cognitive Impairment who have the option to complete a Positron Emission Tomography (PET) Imaging with Pittsburgh Compound B (PiB).
