Active clinical trials for "Alzheimer Disease"

The aim of the study is the analysis of two inhibitors of Ach-E: galantamine and donépézil in over 65 years' old patients suffering from Alzheimer disease (MMSE between 20 and 26) without Alzheimer's medication.

This study attempts to differentiate the clinical responses of Choline Acetyltransferase and Apolipoprotein Epsilon gene polymorphism to donepezil in Alzheimer's Disease patients.

This is a prospective, multicenter, open-label study. Following screening and baseline assessments, eligible patients will be switched to rivastigmine and will enter the 16 week run-in rivastigmine treatment phase. After completion of assessments at the end of the run-in phase, patients who were not sufficiently stabilized on rivastigmine alone will receive add-on memantine to their rivastigmine treatment; patients who were stabilized on rivastigmine alone will have completed and be discontinued from the study.

This is a Phase II, ascending dose study of CPC-201 in patients with dementia of Alzheimer's type to determine the optimal dose titration schedule.

It is widely believed that inflammation contributes to the pathogenesis of AD. TNF has been implicated in both AD and neurological inflammation. Anti-TNF therapy is therefore surmised to be of potential benefit for treating AD.

The primary specific aim of this clinical trial is to determine whether treatment with rofecoxib or naproxen for one year will slow the rate of decline of cognitive function in patients with Alzheimer's disease (AD) as measured by ADAScog.

Memory for action is especially important in everyday life although current literature is not very abundant. The enactment effect (i.e. better memory for performed actions than for verbally encoded sentences) is usually described as a robust effect in aging and can be found in many diseases. Although the enactment effect has been studied for three decades, there is still no consensus on how it enhances memory. Therefore, in order to gain additional insight into the representational basis of the enactment effect, in the present study, the investigators propose to test neurological patients. The investigators suggested that memory for action should be better than memory for verbally encoded information in Alzheimer's disease and Parkinson's disease. If patients with Alzheimer's disease (AD) and Parkinson's disease (PD) have no cognitive assessment during the last 6 months, then they will realize different tests: MMSE (1), HAD (2), a cognitive assessment (3); (4); BREF (5); Assessment of apraxia, (6). Controls will perform the same tests to verify that they have no cognitive impairment. Then, two experimental conditions will be presented in all patients and controls: a first in which participants will have to name drawings (verbal learning) and a second in which they will have to reproduce an action associated with drawings (action learning). Immediately after this learning phase, a recognition task will be available and therefore participants will have to recognize drawings that had been presented previously. The main criteria used in the statistical analysis will be the correct recognition score.

Previous studies showed that anodal tDCS applied over the dorsolateral prefrontal cortex (DLPFC) improved episodic memory performance, indicating a possible use as an intervention for patients suffering from memory impairments. At the same time, only scant evidence (provided by functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS)) exists regarding the underlying mechanisms, thus hindering a more targeted application. The present study aims at establishing a connection between the stimulation-induced change in episodic memory performance on the behavioural level and neurophysiological parameters. TDCS effects and the underlying mechanisms will be compared between different study conditions, receiving either real anodal tDCS or sham stimulation over the left dorsolateral prefrontal cortex during an episodic memory task.

This study is being performed in order to learn more about a new drug (possible as treatment for people with Alzheimer's Disease and other conditions with cognitive dysfunction (memory and attention problems)) and how it is handled by the body by giving the drug to healthy volunteers with different genotypes.

The purpose of this study is to evaluate the pharmacokinetics, safety, and tolerability of new liquid formulations of tricaprilin, with the aim of finding a suitable formulation to advance in development. This is a three-part, part-randomised study that include single-dose, food effect, and titration tolerability in up to 80 healthy participants.
