Filter by:This is a multi-center, observational, feasibility study, to evaluate long term passive data collection, data quality, and user experience of HealthMode Agitation (Apps) to collect motion, location, physiological, and audio data; and eCOA and EMA responses with mobile devices (iPhone, Apple Watch). The purpose of this study is to evaluate and improve HealthMode Apps data collection and usability in subjects experiencing agitation in the context of dementia.
The primary goal of this pilot project is to adapt an evidence-informed on-line psychoeducation program (Tele-Savvy) to address the unique challenges facing informal caregivers of those living with PPA and geared toward achieving caregiver mastery in this population.
Study J4B-MC-OKAA is a Phase 1/2, multi-center, open-label ascending dose, first-in-human study that will evaluate the safety and effect of intra-cisternal LY3884963 administration on progranulin protein (PGRN) levels in patients with frontotemporal dementia with progranulin mutations (FTD-GRN). Two escalating dose (low dose and medium dose) cohorts are planned, as well as one bridging cohort which will allocate patients to receive either low or medium dose. The duration of the study is 5 years. During the first year, patients will be evaluated for the effect of LY3884963 on safety, tolerability, immunogenicity, biomarkers, and efficacy. Patients will follow up for an additional 4 years to monitor safety and changes on selected biomarkers and clinical outcomes.
A phase 3 double blind, placebo controlled study evaluating the efficacy and safety of AL001 in participants at risk for or with frontotemporal dementia due to heterozygous mutations in the progranulin gene.
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.
NPC is a rare, relentlessly progressive, neurological disease and associated with serious morbidity and shortened life expectancy. The purpose of this Expanded Access Program is to provide early access to arimoclomol for patients with Niemann-Pick Type C disease who, in the opinion and the clinical judgement of the treating physician, may benefit from treatment with arimoclomol. Participants will receive treatment with arimoclomol until their doctor finds it does not help them anymore, they withdraw, or the study is stopped for any reason.
Background and objects Amyloid plaques and tau protein are the landmarks of neurodegeneration in Alzheimer's disease (AD). On the other hand, it is reported that cerebral ischemia may induce amyloid plaques and tau protein accumulation. However, it was difficult to in vivo disentangle the complex and dynamic interactions between AD pathophysiology and cerebral vascular injury during the post-stroke cognitive impairment development in the past. With the advent of novel radiotracers specific to cerebral amyloid plaques and tau protein, we aim to conduct a prospective multimodal neuroimaging cohort study to investigate the contribution of vascular injury, amyloid plaque and tau protein to cognitive impairment. Subjects and methods The prospective project plans to recruit patients with vascular cognitive impairment (VCI) (Group A, n=80), Alzheimer's disease/mild cognitive impairment (MCI) (Group B, n = 120), fronto-temporal dementia (FTD) (Group C, n =30), and progressive supranuclear palsy (PSP) (Group E, n = 80). In addition, another 30 healthy people will be recruited as the control group (Group D, n=30). [18F]AV45 and [18F]MNI-958(PMPBB3) PET will be done for imaging cerebral amyloid plaque and tau protein distribution, brain MRI for obtaining structural and functional information, and neuropsychological tests for cognitive performance. Cognitive evaluation will be repeated 18 months after recruitment. In addition, APOE genotyping will be performed as well. By obtaining the neuroimaging information, such as severity of white matter change and infarction, cortical and hippocampal atrophy, and SUVRs of [18F]AV-45 and [18F]MNI-958(PMPBB3) PET, the study will be able to investigate the composite influence of cerebrovascular disease and neurodegenerative pathology on the trajectory of cognitive impairment. Group comparisons will be performed using the Chi-square test, independent t test, Mann-Whitney U test, ANOVA test, and multiple linear regression, where appropriate. Anticipation In this project, we will be able to explore the distribution patterns of amyloid plaque and tau protein among dementia patients with different etiologies, and also evaluate their influence on cognition
This study investigates if electroencephalography (EEG) neurofeedback training is more beneficial than sham feedback training for the improvement of communication, anxiety, and sleep quality in individuals with aphasia. Half of the participants will receive active EEG neurofeedback sessions first, followed by sham feedback sessions in a crossover design. The other half of participants will undergo sham feedback sessions first, followed by active neurofeedback.
The primary objective is to assess the safety and tolerability of Metformin in subjects with C9orf72 amyotrophic lateral sclerosis administered for 24 weeks. The overall objective is to determine if Metformin is safe in C9orf72 ALS patients and is a potentially viable therapeutic treatment for C9-ALS that reduces repeat-associated non-canonical start codon - in DNA (non-ATG) (RAN) proteins that are produced by the C9orf72 repeat expansion mutation.
The purpose of this study is to investigate the feasibility of using repetitive transcranial magnetic stimulation (rTMS) - a form of non-invasive brain stimulation - to improve language functioning in individuals who have the logopenic variant of primary progressive aphasia (PPA-L) - a slowly progressive impairment of language, characterized by difficulties with word-finding, sentence repetition and sentence comprehension.
