The purpose is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Stage 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Stage 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.

The purpose of this research study is to test the study drug, referred to as remternetug, to determine its effectiveness for the study treatment of asymptomatic (at risk) Alzheimer disease in individuals with AD-causing mutations. This study will also investigate the effects of remternetug on biomarkers (measures of the disease including brain scans, blood and spinal fluid tests), examine safety data to identify any potential benefits or risks, and examine how well participants can tolerate remternetug. Stage 1 will determine if treatment with the study drug prevents or reverses amyloid beta (Aβ) accumulation compared with placebo in participants with dominantly inherited Alzheimer's disease (DIAD). Stage 2 will evaluate the effect of early anti-amyloid treatment on downstream biomarkers of AD in treated participants compared to external control groups. Read Less

Up to 25% of intensive care unit (ICU) survivors experience cognitive impairment comparable in severity to mild Alzheimer's disease and related dementias after hospital discharge. Older ICU survivors (ages 60 and older) are at highest risk for delirium and subsequent cognitive impairment, which contribute to higher risk for cognitive decline related to Alzheimer's disease and related dementias. Sleep and activity are essential for recovery from critical illness, yet ICU survivors experience both sleep deficiency and profound inactivity. About 75-80% of ICU patients experience circadian dysrhythmia, which contributes to cognitive decline and increases likelihood of developing Alzheimer's disease and related dementias. The scientific premises of the proposed study are: 1) a combined sleep promotion and cognitive training intervention will have synergistic effects to mitigate the risk of cognitive impairment and development of Alzheimer's disease and related dementias in older ICU survivors; and 2) chronotherapeutic timing of interventions (i.e., adjusting timing of interventions according to circadian rhythm) may improve intervention efficacy.

ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) represents the formalized integration of ARTFL (U54 NS092089; funded through 2019) and LEFFTDS (U01 AG045390; funded through 2019) as a single North American research consortium to study FTLD for 2019 and beyond. Read Less

The goal of this clinical trial is to improve communication among clinicians, patients with memory problems, and their family members. We are testing a way to help clinicians have better conversations to address patients' goals for their healthcare. To do this, we created a simple, short guide called the "Jumpstart Guide." The goal of this research study is to show that using this kind of guide is possible and can be helpful for patients and their families. Patients' clinicians may receive a Jumpstart Guide before the patient's clinic visit. Researchers will compare patients whose clinician received a Jumpstart Guide to patients whose clinician did not receive a guide to see if more patients in the Jumpstart Guide group had conversations about the patient's goals for their healthcare. Patients and their family members will also be asked to complete surveys after the visit with their clinician. Read Less

Alzheimer's Disease and related dementias (AD/ADRD) are common and debilitating conditions. Financial hardship, a multidimensional construct of financial strain, financial stress and asset depletion, is common in AD/ADRD due to exorbitant out-of-pocket spending such as for long-term care, lower work productivity and income for their caregivers that can last for decades after disease onset, and difficulty deciding between nursing home care or home-based care while negotiating insurance coverage. People from historically marginalized groups can experience a double disparity with fewer financial resources to manage AD/ADRD and a greater risk of AD/ADRD. Screening for financial hardship in AD/ADRD is key for addressing the needs of patients and caregivers but critical barriers include a lack of suitable screening measures. Current measures are very general and meant for people without chronic medical conditions or are specific to other diseases. To fill this gap, this study will create a suite of measures that can screen for financial hardship in people with AD/ADRD and their families and caregivers. The measures will include a set to assess caregiver burden; a set to assess patient hardship as reported by the caregiver for patients who cannot report for themselves; and a set of patient-reported measures for patients that are able to report for themselves. To create these financial hardship screening measures, the project will conduct the following aims. Aim 1- Develop financial hardship screening measures for Alzheimer's Disease and related dementias: Using interviews with both caregivers and people with AD/ADRD, key indicators of financial hardship that are unique to AD/ADRD and the point in the lifespan in which it occurs will be identified. The ways that social and caregiver network size affect financial hardship will also be explored. Using the interviews and previous measures, preliminary measures will be created and will be reviewed by experts and a patient and caregiver advisory board. Aim 2- Create item response theory-based screening measures for financial hardship measures in Alzheimer's Disease and related dementias: Large samples of people with AD/ADRD (n=1000) and caregivers (n=1000) will be surveyed and item response theory will be used to evaluate and revise the measures and create scoring algorithms. A sample of additional caregivers matched to primary caregivers (n=400) will also be recruited to evaluate interrater reliability of the measures. Aim 3- Evaluate the financial hardship measures across patient and caregiver populations: Using the sample from Aim 2 and item response theory, we will evaluate the financial hardship screening measures across the following groups to ensure they are unbiased and reflect true differences: race/ethnicity; patient comorbidities; stage of AD/ADRD; caregiver relationship; social network size; number of caregivers; financial support provided; and caregiver's own health status (disability, comorbidities). The resulting measures will improve identification of financial hardship in AD/ADRD. Read Less

The goal of this research is to educate people about different technologies to support care at home when someone is experiencing memory difficulties. "Let's Talk Tech" is a new tool to educate people about technologies commonly used to support care and monitor safety, and help families talk about their feelings about them to understand each other's perspectives. The goal of this clinical trial is to learn if "Let's Talk Tech" helps people feel more prepared to make decisions about technologies. Researchers will compare Let's Talk Tech to usual care (no intervention) to see if Let's Talk Tech increases peoples' preparedness and confidence to make decisions about technologies. Participants will: * Use the Let's Talk Tech web application together with their study partner that takes up to an hour or do nothing. * Complete three surveys. The second survey will be taken within 2 weeks of the first and the last survey will be taken 3 months after the first. Read Less

The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.

High fat feeding (HFF) increases the risk of Alzheimer's disease (AD) but individuals who carry the AD risk gene E4 paradoxically improve after acute HFF. The investigators propose to further study this phenomenon with a clinical study to assess cerebral blood flow which can be measured by a technique called arterial spin labeling (ASL) on an MRI and is tightly related to brain metabolism.
