19 Clinical Trials for Various Conditions
The goal of this clinical trial is to learn if vortioxetine improves mood symptoms and cognition in patients with early-stage behavioral variant Frontotemporal Dementia (bvFTD). The main questions this study aims to answer are: 1. Do individuals with mood symptoms and bvFTD have brain changes and cognitive profiles that differ compared to individuals without bvFTD? 2. Do mood symptoms and cognition improve following treatment with vortioxetine? Researchers will also determine whether there are changes in the brain associated with vortioxetine treatment. Participants will: * Undergo a screening visit that involves clinical assessments and laboratory tests * Undergo an initial brain magnetic resonance imaging (MRI) and fluorodeoxyglucose (18F) Positron Emission Tomography (FDG PET) scan before starting treatment with vortioxetine * Undergo memory and problem-solving tests before starting treatment with vortioxetine * Undergo approximately 12 weeks of treatment with vortioxetine, during which time there will be regular contact and assessments with the study psychiatrist * Undergo a repeat PET scan and repeat memory and problem-solving tests after 12 weeks of treatment with vortioxetine
The primary objective of this study is to enroll an observational cohort of approximately 60 patients with PSP over the course of 24 months using a multicenter study design and to follow each of them for 12 months. The secondary objective of this study is to develop a robust solution for multi-modal remote monitoring of motor symptoms and function in PSP that can be applied to other Frontotemporal lobar degeneration (FTLD) syndromes.
Aims: The study will contribute to our understanding of how the cultivation of caregiver mindfulness might improve their overall relational well-being (Primary Outcome), their psychological well-being (Secondary Outcome), and have an impact on dementia patients' lifestyles (Other Outcome). Overall, this study will investigate the idea that the fruits of mindfulness training can be leveraged by both the caregiver and the care-recipient, improving the quality of relationship by making their interactions more mutual, connected, empathic and positive. This study aims to additionally elucidate which facets of mindfulness account for caregiver's happiness and psychological well-being. Sample: In this study 40 dementia caregivers will be recruited to participate; 20 will be allocated to the clinical intervention group (i.e., adapted MBSR for caregivers) and 20 to the active control group. Data will be collected pre-post the start of intervention, and at a 3 month follow up. Future orientation: This study may contribute to evidence-based knowledge concerning the efficacy of mindfulness based interventions to support caregiver empowerment, via regaining relationship satisfaction and achieving greater equanimity in the face of stressors.
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.
Frontotemporal Lobar Degeneration (FTLD) is the neuropathological term for a collection of rare neurodegenerative diseases that correspond to four main overlapping clinical syndromes: frontotemporal dementia (FTD), primary progressive aphasia (PPA), corticobasal degeneration syndrome (CBS) and progressive supranuclear palsy syndrome (PSPS). The goal of this study is to build a FTLD clinical research consortium to support the development of FTLD therapies for new clinical trials. The consortium, referred to as Advancing Research and Treatment for Frontotemporal Lobar Degeneration (ARTFL), will be headquartered at UCSF and will partner with six patient advocacy groups to manage the consortium. Participants will be evaluated at 14 clinical sites throughout North America and a genetics core will genotype all individuals for FTLD associated genes.
This study is being performed to generate data regarding brain vibration /oscillation differences between individuals with dementia and normal controls. The purpose of this study is to compare signal patterns generated from the impact on the scalp from these brain oscillation patterns from individuals with Alzheimer's disease, Frontotemporal Lobar Degeneration, Mild Cognitive Impairment and Age-Matched Normal Controls.
Background: - Some people have a mutation in the C9ORF72 gene that causes amyotrophic lateral sclerosis (ALS) or frontotemporal dementia (FTD). The mutation causes a small piece of DNA to repeat itself thousands of times. The C9ORF gene mutation mostly occurs in families. In those families, some persons have ALS and others have FTD. Occasionally the C9ORF gene mutation occurs in persons without a family history. Researchers want to understand how this gene causes different diseases. They will study how symptoms caused by the C9ORF gene develop and change over time. They will measure symptoms that occur in ALS and in FTD. In particular, they will measure strength, ability to move, thinking, and memory. They will also see if other tests are associated with progression of disease. These tests, called biomarkers, may help detect or measure C9ORF72 disease in the future. Objectives: - To understand how symptoms change over time in people with mutations in a gene called C9ORF72, which causes ALS and FTD. Eligibility: - Adults over age 18 who have this genetic mutation Design: * Participants will have up to 4 in-person visits and 3 telephone interviews over 3 years. Each in-person visit may take place over several days. They may be either inpatient or outpatient visits. * At each visit, participants will undergo a series of brain, language, and behavior tests. These will include: * Magnetic resonance imaging (MRI) of the brain. This uses magnets, radio waves, and computers to produce detailed pictures of the brain. * Collecting spinal fluid. The clinician will make the participant s back numb and then insert a needle to collect fluid. \<TAB\>- Blood samples will be taken. \<TAB\>- Participants will be asked to perform several language and movement tests. \<TAB\>- Small skin samples will be taken on one visit - Between visits, participants will answer questions about their health over the phone 3 times.
This study measures whether the symptoms of frontotemporal dementia (FTD) can be successfully treated by (a) biofeedback training to increase brain blood flow, (b) biofeedback to increase the frequency of the brain's dominant brainwave rhythm, and (c) rhythmic stimulation to increase the brain's dominant brainwave frequency.
This study will use positron emission tomography (PET) imaging to measure a receptor in the brain that is involved in inflammation. Certain neurological disorders, possibly including frontotemporal dementia (FTD), are associated with increased inflammation in the brain. This study may help elucidate the relationship between FTD and inflammation. Patients with FTD and healthy volunteers who are 35 years of age or older may be eligible for this study. Candidates are screened with a medical history, physical examination, electrocardiogram, and blood and urine tests. Participants undergo the following procedures: * Whole body PET scan: PET uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. The tracer used in this study is \[11C\]PBR28. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. Pictures are taken for 1 hour. This short scan is done to determine if \[11C\]PBR28 binds to the subject s receptors, since a number of people do not have binding. Subjects who have binding continue with brain PET and MRI scans, described below. * Brain PET imaging: Before starting the scan, a catheter is placed in a vein in the arm to inject the tracer,\<TAB\> and another catheter is placed in an artery in the wrist to obtain blood samples during the scan. The subject lies on the scanner bed. A special mask is fitted to the head and attached to the bed to help keep the person s head still during the scan so the images will be clear. An 8-minute transmission scan is done just before the tracer is injected to provide measures of the brain that are helpful in calculating information from subsequent scans. After the tracer is injected, pictures are taken for about 2.5 hours, while the subject lies still on the scanner bed. * Blood and urine tests are done the day of and the day following each PET scan. * Magnetic resonance imaging (MRI): An MRI scan is done within 1 year (before or after) of the PET scan. This procedure uses a magnetic field and radio waves to produce images of the brain. The subject lies on a table that is moved into the scanner (a tube-like device), wearing earplugs to muffle the noise of the machine during the scanning process. The test takes about 1 hour....
This study will test the effects of a medication called tolcapone on cognitive, behavioral, and language problems seen in patients with frontotemporal dementia (FTD). Tolcapone increases the amount of dopamine, a brain chemical that may be lowered in FTD. The study will see if tolcapone can improve thinking, behavior, and language in people with FTD and will look at the effects of the drug on brain activity. Patients with FTD who are between 40 and 85 years of age may be eligible for this study. Participants will be seen as outpatients at the Columbia University Medical Center approximately one a week for 4 weeks. They take tolcapone or a placebo (a look-alike pill with no active ingredient) during study week 1. During study week 3, those who took placebo during week 1 now take tolcapone for 1 week and those who took tolcapone now take placebo. In addition, patients undergo the following tests and procedures: * Neurological tests to evaluate attention, problem-solving and memory. These tests are repeated several times during the course of the study. * Test to look for a gene that affects the amount of dopamine in the brain, using blood samples collected in a previous study. * Blood draws four times during the study. * Functional MRI (fMRI) to learn about changes in brain regions that are involved in performing tasks. For fMRI, the patient lies on a table that can slide in and out of the scanner, a narrow metal cylinder surrounded by a magnetic field. The procedure takes about 60 minutes and is performed four times over the course of the . FMRI involves taking pictures of the brain during MRI while the subject performs a task so that changes in the brain that occur during these tasks can be studied.
Objectives. The proposed clinical study has two goals: First, to assess the efficacy of a central nervous system stimulant and an atypical antipsychotic in treating the behavioral symptoms of FTD and second, to further characterize the biological markers, including genetic, imaging, and CSF proteins, of FTD in relation to our existing group of Alzheimer's patients. Rationale. Frontotemporal dementia (FTD) is increasingly recognized as an important neuropsychiatric disorder. Symptoms of FTD include disinhibition, impulsivity, apathy, affective lability, and language dysfunction. The clinical syndrome is associated with frontal and/or anterior temporal atrophy on imaging and autopsy. Levels of the CSF proteins tau and (Beta)-amyloid 1-42, shown to have diagnostic utility in patients with Alzheimer's Disease (AD), have also been found to be abnormal in FTD. FTD is less associated with APOE genotype than AD, however some familial cases of FTD are associated with specific mutations in the gene encoding the tau protein. Currently, no treatments have been proven to be effective for altering the course or clinical symptoms of FTD. Design. Study subjects will include 50 male and female patients with mild-moderate frontotemporal dementia recruited from participants in NINDS protocol 02-N-0001. In a double-blinded crossover 11-week study without a placebo control, patients will be treated with a stimulant (dextroamphetamine) and an atypical antipsychotic (quetiapine). The primary outcome measures will be the Neuropsychiatric Inventory and the Clinical Global Impression of Change. Cerebrospinal fluid, cognitive and genetic measures, brain MRIs, and side effects scales will also be collected.
This is a biomarker study designed to collect and analyze blood specimens from individuals carrying known familial frontotemporal lobar degeneration (f-FTLD) mutations compared to a control group of individuals without known f-FTLD mutations. The NSP is an ancillary study to the ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration" (ALLFTD) study, NCT04363684. More information can be found at https://www.allftd.org/.
The study will investigate the ability of a new PET tracer, 18F-AV-1451, to detect depositions of a protein, called tau, in the brains of people with a mutation in the tau gene that causes deposition of the protein, and in people without the mutation. Up to three 18F-AV-1451 scans will be performed (one per year) on control subjects without MAPT mutations, presymptomatic mutation carriers, and symptomatic mutation carriers.
This is a randomized clinical trial evaluating the benefits of a program that supports model care for persons with dementia and their family caregivers. Subjects were recruited from California, Nebraska and Iowa. Subjects determined to be eligible were consented and randomized into one of two groups. Two thirds of patients were enrolled into Navigated Care that provided them with assistance in meeting important benchmarks in their care, for example completion of legal and financial planning and strategies for minimizing caregiver burden. One third of patients were enrolled to a control group, entitled Survey of Care. Outcomes include quality of life, health care utilization, caregiver burden, satisfaction with care, caregiver depression, and caregiver self-efficacy.
The general purpose of this observational study is to examine biomarkers associated with the pathology of neurodegenerative diseases to potentially develop novel therapeutic approaches.
Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA. The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.
This is a study on Internet-based video-practice speech and language therapy for persons with primary progressive aphasia (PPA), behavioral-variant frontotemporal dementia (bvFTD), or related conditions.
This study will measure the function of a protein called P-glycoprotein (P-gp), which is found at the blood-brain barrier, a membrane that normally prevents toxic material from entering the brain. Impaired P-gp function may allow toxins to enter the brain and cause some people to develop certain brain diseases. Healthy subjects and people with Alzheimer s disease, Parkinson s disease or frontotemporal dementia who are 35 years of age or older and in overall good health may be eligible for this study. Participants undergo the following procedures during three outpatient visits to the NIH Clinical Center: * Medical history, psychological evaluation, physical examination and blood and urine tests, including tests for illegal and addictive drugs. * PET scan: This test uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. The subject lies on the scanner bed, with a special mask fitted to the head and attached to the bed to help keep the head still during the scan so the images obtained are clear. A brief initial scan is done to calibrate the scanner. Then, a radioactive tracer called \[(15)O\]H(2)O is injected into the catheter and the PET camera takes pictures of blood flow to the brain for about 60 seconds. Next, another tracer, \[(11)C\]dLop, is injected into the catheter and pictures are taken for about 2 hours to determine how much of this tracer is allowed to enter the brain. * Magnetic resonance imaging (MRI): This procedure is done within 1 year (before or after) the PET scan. MRI uses a magnetic field and radio waves to produce images of the brain. For this procedure, the patient lies on a table that can slide in and out of the scanner (a tube-like device), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scan.
The purpose of this study is to further define the neurological and linguistic deterioration in primary progressive aphasia.
