Active clinical trials for "Aphasia, Primary Progressive"

Study 18F-AV-45-010 is designed to evaluate the cerebral uptake of florbetapir 18F as measured by PET imaging in frontotemporal disorder (FTD) in comparison to cognitively normal volunteers and subjects with Alzheimer's disease (AD).

Pick's disease, also known as Pick disease,or FTD is a rare fronto-temporal neurodegenerative disease. This study will investigate the use of far infrared radiation for the control, management and treatment of Pick's disease.

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.

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.

The overall goal of this imaging trial is to evaluate [18F]PI-2620, a tau targeted positron emission computed tomography radioligand, in individuals with tauopathies and healthy volunteers (HV).

The study is designed to assess the demographic, clinical and imaging associations with the presence of microbleeds in atypical Alzheimer's disease. The primary hypothesis is that cognitive and functional performance will be poorer in atypical Alzheimer's subjects with microbleeds compared to those without microbleeds.

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.

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.

Analysis of gaze patterns during social cognition tasks and standardised exploration of a specific artwork, between elderly subjects without cognitive disorders and subjects with neurodegenerative diseases such as Fronto-Temporal Dementia, Alzheimer's Dementia or Parkinson's Disease

Alzheimer's disease (AD) and frontotemporal dementia (FTD) are two of the most common types of age-related neurodegenerative disorders. Identifying at-risk patients and gauging disease progression in a non-invasive manner would be invaluable. Early and correct diagnosis is crucial for coordinating supportive care, patient expectations, caregiver arrangements and family planning. In addition, as treatments become available, beginning therapy early in the disease before symptoms become severe will be important. Multimodal ocular imaging (MOI) includes an ophthalmic (eye) exam and eye photographs to evaluate different layers of the retina, which is the light sensing layer of the eye. Newer technologies make it possible to visualize the disease process occurring in AD and FTD by using MOI to look at the retina, since the retina is fundamentally an outward extension of the brain itself. This study will attempt to correlate signs of disease in the retina, as determined by MOI, with plaque buildup in the brain as seen by imaging. This will demonstrate the sensitivity and specificity of MOI for diagnosing AD and FTD in a noninvasive manner.
