Filter by:This study will re-read 10-minute positron emission tomography (PET) scans acquired in previous clinical studies of AV-45 at 30 and 50 minutes after injection and compare the results.
This study will test if two AV-45 PET scans up to 4 weeks apart in AD subjects and healthy volunteers provide the same results. The study will also test two different AV-45 injection methods in a small subgroup of enrolled AD subjects (slow vs. fast bolus group).
This study will test two different doses of florbetapir F 18 to determine which dose is best to image amyloid plaques in the brains of Alzheimer's Disease (AD) patients using a positron emission tomography (PET) scanner.
A preliminary study to test how florbetapir F 18 (18F-AV-45) acts in the brains and bodies of healthy elderly people and patients with Alzheimer's Disease (AD) by using a positron emission tomography (PET) scanner.
This study will determine how florbetapir F 18 (18F-AV-45) radioactivity is distributed throughout the body.
The purpose of this study is to evaluate the changes in the cognitive, functional, behavioral and global domains based on the different applicable psychometric batteries and scales.
The purpose of this clinical study is to investigate the safety and efficacy of deep brain stimulation (DBS)as a treatment option for patients with cognitive, behavioral, and functional disability of Alzheimer's disease.
A few studies suggest that patients suffering from neurodegenerative diseases (such a multiple sclerosis or Alzheimer's disease (AD)) show decreased thickness of the retinal nerve fiber layer (RNFL), indicating axonal degeneration. High-definition spectral domain optical coherence tomography (SD-OCT), performed without radiation in a few seconds per eye, offers a precise and standardized estimation of this parameter, which could constitute a biomarker for cerebral axonal degeneration. These RNFL deficits might even be the earliest sign of AD, prior to damage of the hippocampal region that impacts memory. Besides, some associations of AD with some degenerative diseases of the eye (glaucoma, microvascular abnormalities, age-related macular degeneration (AMD)) have also been reported. It therefore seems interesting to determine whether RNFL thickness, and other ocular parameters, may give some indications for a better detection of AD and cognitive decline in the elderly.
The main purpose of this research project is to study how seizure-like activity affects the blood flow in the brain of patients with Alzheimer's disease (AD). Changes in blood flow can change memory and thinking ability, as happens in Alzheimer's disease. The investigators are using a study drug called Levetiracetam, which helps control seizure-like activity to see if it can help change the abnormal blood flow in the brain that is seen in some people with Alzheimer's disease.
This study was planned 1) to identify individuals with Mild Cognitive Impairment (MCI) who convert to Alzheimer's Disease (AD), and 2) to explore factors associated with the conversion.
