Genetic Characterization of Movement Disorders and Dementias

Background: There are two basic types of movement disorders. Some cause excessive movement, some cause slowness or lack of movement. Some of these are caused by mutations in genes. On the other hand, dementia is a condition of declining mental abilities, especially memory. Dementia can occur at any age but becomes more frequent with age. Researchers want to study the genes of families with a history of movement disorders or dementia. They hope to find a genetic cause of these disorders. This can help them better understand and treat the diseases. This study will not be limited to a particular disorder, but will study all movement disorders or dementias in general. This study will perform genetic testing to identify the genetic causes of movement disorders and dementia. Today, genetic testing can be done to analyze multiple genes at the same time. This increases the chances of finding the genetic cause of movement disorders and dementias. Objectives: To learn more about movement disorders and dementia, their causes, and treatments. Eligibility: Adults and children with a movement disorder or dementia, and their family members. Healthy volunteers. Design: Participants will be screened with medical history and blood tests. Some will have physical exam. Participants will give a blood sample by a needle in the arm. This can be done at the clinic, by their own doctor, or at home. Alternatively, a saliva sample may be provided if a blood sample cannot be obtained. Participants can opt to send an extra blood sample to a repository for future study. Genetic test will be done on these samples. The samples will be coded. The key to the code will remain at NIA. Only NIA investigators will have access to the code key. Participants can request to receive results of the tests. Participation is generally a single visit. Participants may be called back for extra ...

PET Imaging of Cyclooxygenases in Neurodegenerative Brain Disease

Background: About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation. Objective: To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers and to determine retest variability and reliability for each radioligand and the possibility of avoiding arterial sampling by using a bolus + constant infusion (B/I) paradigm. Eligibility: Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, or Huntington s disease and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181. Design: Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured. Participants will have a magnetic resonance imaging (MRI) scan. The MRI scanner is a metal tube surrounded by a strong magnetic field. Participants will lie on a table that slides in and out of the tube. The machine makes noise. Participants will get earplugs. Participants will have 2 PET scans. They will be injected with the study drugs through an intravenous catheter placed in an arm vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A plastic mask will be molded to their head to keep them from moving. A thin plastic tube will be put into an artery at the wrist or elbow crease area. This will be used to draw blood during the scan. Participants will have 2-3 study visits. Participation lasts 1 week to 4 months, depending on scheduling.

Project to Improve Communication About Serious Illness--Hospital Study: Comparative Effectiveness Trial (Trial 2)

The objective of this protocol is to test the effectiveness of a Jumpstart intervention on patient-centered outcomes for patients with chronic illness by ensuring that they receive care that is concordant with their goals over time, and across settings and providers. This study is particularly interested in understanding the effect of the intervention to improve quality of palliative care for patients with Alzheimer's disease and related dementias (ADRD) but will also include other common chronic, life-limiting illnesses. The specific aims are: 1) To evaluate the effectiveness of a survey-based patient/clinician Jumpstart guide compared to an EHR-based clinician Jumpstart guide for improving quality of care; the primary outcome is documentation of a goals-of-care discussion during the hospitalization. Secondary outcomes include: intensity of care (ICU use, ICU and hospital length of stay, costs of care during the hospitalization, and 30-day hospital readmission); patient- and surrogate/family-reported outcomes assessed by survey at 1 and 3 months after randomization including occurrence and quality of goals-of-care communication in the hospital, goal concordant care, psychological symptoms, quality of life, and palliative care needs. 2) To conduct a mixed-methods evaluation of the implementation of the intervention, guided by the RE-AIM framework for implementation science, incorporating quantitative evaluation of the intervention's reach and adoption, as well as qualitative analyses of interviews with participants, to explore barriers and facilitators to future implementation and dissemination.

MEMORI Corps: Activity-based Companion Care for Dementia

This is a single blind, intention-to-treat, randomized controlled trial design to evaluate the feasibility and efficacy of a 12-week, evidence-based, individualized MEMORI Corps program delivered by trained older volunteers (n=80) to community-living PWD/CG dyads (n=240). Eligible PWD/CG dyads will be randomized to receive 12-weeks intervention group (n=120), or 12-week augmented waitlist control group (n=120) followed by 12-weeks of intervention. Eligible volunteers will be randomized to 12 months of MEMORI Corps active duty (n=40) where the participants will be matched to three families over the course of a year, or a 12-month augmented waitlist control group (n=40) followed by opportunity to serve 12 months active duty in MEMORI Corps. Program goals are to address unmet respite care needs for family caregivers, provide persons with dementia meaningful evidence-based activity programming, as well as provide health benefits, meaningful productive engagement, and peer support opportunities for senior volunteers.

Inhalational Anesthesia and Precipitation of Dementia: is There a Link?

Many elderly patients undergoing surgical procedures already have impaired cognitive (memory/concentration) status. Patients with pre-existing cognitive impairment, or dementia, may benefit from modified anesthesia techniques. It is estimated that one in eight people age 65 and older has Alzheimers disease. More so, nearly half of people that are 85 years or older have Alzheimers disease. Currently, both spinal (regional) and inhalational (general) anesthesia, are used in patients undergoing common urological, orthopedic, and general surgical procedures. Inhalational anesthesia has been associated with higher risk of memory impairment in experimental (animal) and human studies. However, currently, there are simply no large or good enough studies to be sure that inhalational anesthesia is responsible for causing dementia and Alzheimers disease.The proposed study investigates if elderly patients (65 years and older) undergoing spinal anesthesia (patient is awake or slightly sedated) are less likely to develop dementia and Alzheimers disease for up to 2 years after surgery, when compared to inhalational anesthesia (patient is kept asleep with gas anesthetic). The investigators will also test all patients for the presence of apolipoprotein (ApoE-Î?4 type of gene that is present in 15-20% of patients), and beta-amyloid tau protein (present in cerebrospinal fluid) that are known risk factors for Alzheimers disease. The particular strength of this study is that it takes into account whether the frequency and/or severity of dementia and Alzheimers disease is different in patients with and without these markers. The investigators believe that this study will make a major contribution to better understanding of development of Alzheimers disease.

Virtual Individual Cognitive Stimulation Therapy: a Proof of Concept Study

Due to COVID-19, the routine treatment for dementia, Cognitive Stimulation Therapy (CST), is currently suspended in multiple countries. Access to treatment is, therefore, paramount. The investigators seek to bridge the current treatment gap with a virtual and individual form of CST, called Virtual Individual Cognitive Stimulation Therapy (viCST). This psychosocial intervention was adapted from the key principles of CST and developed within the Medical Research Council (MRC) framework for complex interventions. The investigators aim to evaluate the feasibility and acceptability of viCST in a Randomized Controlled Trial. This is a feasibility randomized controlled trial (RCT) for Virtual Individual Cognitive Stimulation Therapy (viCST), an evidence-based teletherapy for people with mild to moderate dementia. This psychosocial intervention is adapted from a routine and established dementia treatment, Cognitive Stimulation Therapy, and developed within the Medical Research Council (MRC) framework for complex interventions.

Fasudil fOr redUcing elopemeNt and Spatial Disorientation

Fasudil, a Rho kinase inhibitor, is believed to reduce wandering behaviors of elopement and getting lost by improving spatial memory and navigation through improvements in hippocampal blood flow. Fasudil is non-sedating. The aim of the study is to assess the effectiveness of oral fasudil in reducing wandering behaviors of elopement and/or getting lost in subjects with dementia. In addition, effects on wandering behaviors of excess movement and pacing, cognition, memory, neuropsychiatric symptomatology, caregiver/nursing staff burden, and the safety and tolerability of fasudil treatment will be assessed.

Physical Activity, Alzheimer's Disease and Cognition Relative to APOE Genotype

Physical activity and Alzheimer's disease (PAAD-2) is a randomized control trial that will assess the effects of exercise on middle-aged (40-65 years) cognitively normal adults who have a heightened risk of Alzheimer's disease (AD) due to family history (FH+). The investigators will also assess the extent to which this effect is moderated by apolipoprotein epsilon-4 (APOE4) carrier status, and will gather critical new experimental evidence on the use of physical activity to improve cognitive performance by persons at the greatest risk of Alzheimer's disease.
