Filter by: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.
Primary progressive aphasia (PPA) is a neurodegenerative disease that affects first and foremost language abilities. Mild cognitive impairment (MCI) is slowly progressive decline in a single domain of cognition (e.g. language) not attributable to motor or sensory loss, without impediment of social or occupational function. MCI can be an early sign of neurodegenerative disease, or can be due to normal aging. When language is the prominent affected domain in MCI, the person may later meet criteria for PPA or may progress to the clinical syndrome of Alzheimer's dementia. Spelling, naming, and working memory (e.g. repetition) are among the language abilities affected early in the course of PPA or language-centered MCI, and different variants have distinct deficits in these domains. This research project investigates the behavioral and neuromodulatory effects of high definition transcranial direct current stimulation (HD-tDCS) during language therapy in PPA participants over time. Anodal HD-tDCS targeting the left inferior frontal gyrus (IFG) administered in combination with language therapy is expected to be more beneficial when compared to language therapy alone. It will 1) improve language performance or decrease rate of decline, 2) have better-sustained effects at 2 weeks and 2 months post-treatment, and 3) produce generalization to untrained language items and some other cognitive functions. Resting-state fMRI, diffusion tensor imaging (DTI), and volumetric data are also collected to investigate changes in functional brain connectivity associated with HD-tDCS in individuals with PPA. A better understanding of the therapeutic and neuromodulatory mechanisms of HD-tDCS as an adjunct to language therapy in PPA may have a significant impact on the development of effective therapies for PPA and MCI, and may offer insight into ways of impeding neurodegeneration that may improve patients' quality of life, as well as extend their ability to work and manage their affairs.
This study will establish factors fundamental to the improvement in communication and quality of life for people with dementia known as primary progressive aphasia (PPA). PPA is a type of dementia in which language declines but other cognitive skills (including memory) are preserved in the first several years after the onset. This makes those in the initial stages of PPA excellent candidates for treatment and creates a window of time (2-7 years) whereby they can lead independent lives with minimal support. However, currently, no communication therapy is available to people with PPA due to the progressive nature of the disorder and lack of awareness of available options for professionals willing to treat it. Participants with PPA in our study will receive two kinds of therapy for the words they cannot recall spontaneously, and will be trained to maintain them through social interaction. The type of training will be based on the most successful interventions the investigators provided to people with PPA in our previous work. The investigators expect that successful re-learning of forgotten words and practicing them in a group setting will facilitate retention of communication skills leading to greater personal independence and increased/maintained quality of life for people with PPA. Our study represents natural combination of two novel approaches for PPA that ultimately will lead to lower demands on the health care system.
Due to different study designs, the sponsor separated Part C into a separate registration (NCT04958642), leaving Parts A/B here in NCT02534844. This study is to find out how safe and effective VTS-270 is for patients with Niemann-Pick Type C1 (NPC1) disease who have neurologic symptoms (listed under Keywords). In Parts A/B, two out of every three patients will receive the study drug. The third patient will receive 1 to 2 small needle pricks at the location where the LP and IT injection is normally made (sham control). In Part C, all participants will receive study drug, as described in the Part C registration record. Start date for this record is the first day a participant was enrolled in Parts A/B. The trial is actually continuing until the last primary outcome measure of safety data are collected from Part C participants. The last primary outcome measure of safety, along with final adverse events results will be posted in the separate Part C registration record.
This study is being done to test the feasibility and effectiveness of web-based social-cognitive training exercises in treating social-emotional deficits in patients with stroke or frontotemporal dementia (FTD).
The purpose of this study is to provide relevant quantitative evaluation of apathy close to real life situation by means of a multimodal sensor system integrated.
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 is a prospective non-therapeutic observational study in NP-C patients. The aim is to characterize the individual patient disease progression profile through the historical and 6 months prospective evaluation of clinical, imaging, biological(biomarkers) and quality of life data. Patients will be offered enrollment into a Phase II/III study on arimoclomol at the end of the study.
This study is being done to learn more about normal thinking and behavior, mild thinking and behavior problems, Frontotemporal Dementia and other forms of dementia in families in which one or more relatives have a mutation associated with Frontotemporal Dementia.
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.
