Filter by:This protocol is designed to serve as a pre-screening study for subjects who are potentially eligible for Alzheimer's Disease (AD) therapeutic trials that require tau imaging for inclusion by means of a flortaucipir F18 Positron Emission Tomography (PET) scan.
This is a proof of concept study to determine if changes in brain amyloid levels are evident three months after infusion of 0.4 g/kg of IVIG every 14 days x 5 infusions. Amyloid levels will be measured by Florbetapir PET and retinal scan.
The aim of this study is to evaluate the oxidative stress and brain damage biomarkers induced by tDCS in patients with AD and to assess the long term neurophysiological and behavioral effects after repeated daily tDCS sessions for 10 days. Thirty AD patients diagnosed according to 2011 McKhann criteria will be randomly assigned to receive 10 real anodal tDCS or sham at 2mA intensity for 20 minutes per session daily. All patients will be evaluated at baseline, at the end of the sessions and 1, 2, and 3 months later with neurophysiological and behavioral examination.
A randomized placebo-controlled trial to evaluate the safety and efficacy of three doses of study drug LY3154207 treated for 12 weeks in participants with mild-to-moderate dementia associated with LBD (PDD or DLB).
The purpose of this study is to examine cross-sectional associations between CSF markers of synaptic injury (Ng and SNAP-25) and functional connectivity in default and semantic memory networks using 3T- fMRI in individuals with MCI (i.e. the earliest clinically detectable stage of cognitive impairment) due to AD or mild AD dementia (CDR 0.5-1; n=20) and cognitively normal controls (CDR 0; n=20).
This study will measure the risks and benefits of early screening of Alzheimer's disease. Early diagnosis through screening may enhance the family member's transition to a family caregiver and reduce caregiver burden by providing an opportunity for the family member to learn about the syndrome, receive interventions, and to prepare for their new care giving role.
Degenerative dementias including Alzheimer's Disease (AD), Parkinson's Disease with Dementia (PDD), Dementia with Lewy Bodies (DLB), Frontotemporal Dementias (FTLD), Corticobasal Degeneration (CBD) and Progressive Supranuclear Palsy (PSP) constitute a significant, and growing burden with an estimated cost to the US healthcare system for 2016 of $236 Billion (1). Definitive diagnosis of these dementias is based on pathological criterion upon autopsy, which presents a significant challenge to establish diagnosis in living patients. Although clinical diagnostic criteria have been developed for several of these disorders, including for Alzheimer's Disease (AD) by the National Institute of Neurological and Communicative Disorders and Stroke and Alzheimers Disease and Related Disorders Association (NINCDS-ADRDA) , Parkinson's Disease (PD) by the United Kingdom Parkinson Disease Brain Bank Diagnostic Criteria (UKPDBB) diagnostic criteria for Parkinson Disease(4) and others, the currently available tests, including the use of imaging markers and Cerebrospinal Fluid (CSF) biological markers do not provide a definite diagnosis since this requires the observation of characteristic neuropathological changes in specific regions of the brain.
This Phase 1 randomized, placebo-controlled, double-blinded, first-in-human study will evaluate safety, tolerability, and pharmacokinetics of single and multiple ascending doses of NDX-1017 in healthy young and elderly subjects, and elderly subjects with amnestic mild cognitive impairment (MCI), Alzheimer's disease (mild, mild-to-moderate, or moderate), or mixed dementia with Alzheimer's and vascular components (mild, mild-to-moderate, or moderate).
Alzheimer's Disease (AD) is characterized by amyloid-β (Aβ) plaque buildup and phosphorylated tau (p-tau) in the brain, as well as widespread neurodegeneration. The evidence suggests that both amyloid and tau play a critical role in AD and interventions that reliably and safely decrease the intracerebral burden of amyloid or tau could potentially be of marked clinical importance. Currently, therapeutic options are very limited and while there are pharmacologic interventions that transiently improve cognitive function, there are no treatments that alter disease progression. The current study seeks to use a novel therapeutic intervention that uses noninvasive brain stimulation to target amyloid in the brain. The investigators anticipate this will decrease the amyloid levels in the brain, as evidence by Positron Emission Tomography (PET) imaging.
The research program explores how aging influences brain function in test-persons from a Danish birth cohort of men born in 1953.
