Active clinical trials for "Alzheimer Disease"

Ultimately a marker of microglial activation could be used for large-scale quantitative brain imaging trials in Alzheimer Disease (AD), Parkinson Disease (PD) or Multiple Sclerosis (MS), specifically to investigate the agent as an objective biomarker in treatments aimed at reducing inflammatory changes in these conditions. The significance of this work lies in applying state-of-art quantitative neuroimaging tools to develop a relevant biomarker in individuals with neurodegenerative diseases with the intention of using this efficiently in large clinical imaging trials.

The purpose of this trial is to test the ability of the non-steroidal anti-inflammatory medications naproxen and celecoxib to delay or prevent the onset of AD and age-related cognitive decline.

This study will evaluate the performance of Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) in patients with Alzheimer's disease (AD).

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 study will evaluate whether visual interpretation of flortaucipir-PET (positron emission tomography) scans, examining patterns of tracer uptake at baseline, can predict the rate of clinically-meaningful cognitive decline due to AD after 18 months. All scans are acquired from cohorts of a previously completed study, I8D-MC-AZES (NCT02245737, lanabecestat, Eli Lilly and Company sponsor).

By doing this study, researchers hope to learn if older adults with and without cognitive impairment can adhere to a Mediterranean diet.

Alzheimer disease is hard, long and expensive to diagnose. In order to help the clinician, a new biomarker in Alzheimer disease seems to be very useful. The retina, as a window of the brain, could offer a new way to diagnose this common disease. Indeed, a retinal atrophy could especially appear in Alzheimer disease. Besides, many aspects about retinal alteration, visual function and their link with the disease deserve to be more explored. So as to fill these gaps, a new study about retinal specificity in Alzheimer disease appears to be relevant.

The investigators will compare cognitition, mood (depression), ADL, and brain structural and functional MRI before and after 4-week transcranial magnetic stimulation in patients with mild to moderate Alzheimer's disease. The investigators also compare the change of cognitition, mood (depression), ADL, and brain structural and functional MRI between TMS group and sham coil group.

When older patients develop cognitive problems - like memory loss - there may be any of several underlying causes, sometimes occurring in combination. Clinicians have a better chance of providing appropriate treatment if they understand what the cause of the problem is. A diagnostic tool can help the patient by helping the clinician to make a more accurate diagnosis. This study investigates whether a new diagnostic tool - beta amyloid imaging - may potentially improve medical practice. The tool can potentially improve practice only if it can influence clinical judgment. This study investigates whether the provision of beta amyloid imaging information influences clinical judgment. The investigators will conduct a survey that presents clinicians with descriptions of hypothetical older patients with cognitive complaints. Some of the respondents also receive beta amyloid imaging information. The investigators will test the investigators hypothesis that the information will affect diagnostic judgment and management recommendations by comparing the responses of clinicians who receive the beta amyloid information to the responses of clinicians who do not.
