The objective of this study is to identify early and accurate semantics markers of Alzheimer's disease (AD) by using two types of methods. First, the investigator will evaluate semantic processing of patients with AD or related disorders which will be compared to age matched controls by taking neuropsychological tests. Then, the investigator will analyze the effect of contextual word predictability on eye movements in reading sentences with the help of the same participants by...
Unrandomized, unblinded, monocentric comparative Functional Magnetic Resonance Imaging study.
This study will evaluate the performance of the CogState computerized neuropsychological battery, ADAS-cog and ADCS-ADL in patients with mild-to-moderate Alzheimer's disease.
Alzheimer's disease often manifests as a memory disorder before dementia develops. Dementia is considered to be present when a person can no longer handle complex activities of daily living, such as managing finances. This study will investigate the relationship between changes in the ability to manage finances and brain perfusion, which will be measured using continuous arterial spin-labeling (an experimental MRI). Subjects will also undergo neuropsychological tests focusing o...
Cognitive disorders in Parkinson's disease (PD) are not as obvious as cognitive disorders in Alzheimer disease and their diagnosis tends to be delayed. If neuropsychological assessment of cognitive decline in Parkinson's disease is well established, the thresholds of cognitive testing corresponding to a dementia are unknown. Recently, new diagnosis criteria of dementia associated with PD have been proposed by the movement disorder society. In this study two groups of patients w...
The purpose of this study is to test whether two new cognitive "stress tests" may help distinguish between people at lower or higher genetic risk of Alzheimer's Disease. The investigators are trying to understand how these cognitive "stress tests" work in people who have not been diagnosed with Alzheimer's Disease and are not exhibiting symptoms of Alzheimer's Disease. Study subjects will undergo testing of memory and executive function during functional magnetic resonance imag...
Aims 1. To determine whether the 4 Mountains test of allocentric (i.e. viewpoint-independent) spatial memory, and tests of memory for a recent experience (e.g. watching a brief video), to diagnose the early stages of Alzheimer's disease. 2. We operationalise this as the ability of these tests to predict whether or not an individual progresses from having some cognitive difficulties (diagnosed as 'mild cognitive impairment' MCI) to subsequently de...
In AD (Alzheimer disease), the anatomic correlates of attention disorders (as evaluated by motor slowing) have not been thoroughly characterized.
Currently, no cures or disease modifying therapies exist for Alzheimer's disease (AD). This is partially due to the inability to detect the disease before it has progressed to a stage where there are clinical manifestations. The identification and validation of high throughput biomarkers to measure disease progression (as well as identify pre-clinical disease onset) is critical to the development of disease-modifying or even preventative therapies. In this study, we are testing...
This study is being done to learn about tau tangles in Alzheimer's disease. A type of positron emission tomography (PET) scan is used to measure the abnormal accumulation of protein called tau in the brain. These are thought to be involved in Alzheimer's disease. The investigators will also perform brain MRI and to tests to measure the participant's memory and thinking.
Background: - Individuals who demonstrate symptoms of Alzheimer's disease, such as progressive memory loss, may be eligible to participate in National Institutes of Health research studies. However, other physical and psychological conditions may produce symptoms similar to those of Alzheimer's disease. To determine whether a patient meets the eligibility criteria to participate in a research protocol, researchers must perform a series of diag...
The purpose of the study is to investigate the effect of High Density- tDCS (HD- tDCS) on cognitive function in Alzheimer's Disease. One anode and four return electrodes are placed over DLPFC, where low intensity current (2mA) is induced to the surface of the scalp. Electrode placement is individualized for each participant. Participants will undergo 15 stimulations, with a duration of 20 minutes each. All patients will undergo neuropsychological assessment and MRI evaluation.
The purpose of this study is to test the efficacy and safety of an investigational medication for improving symptoms of Alzheimer's Disease. Subjects will receive either active medication or placebo for 28 days. Tests of memory, concentration will be included. Safety will be monitored using routine clinical and laboratory tests.
Investigators propose in this study to evaluate prospective memory (MP) in all its complexity as well as the processes, cognitive and brain, the underlying. Specifically, investigators propose to evaluate the evolution of the MP during normal aging and Alzheimer's disease (AD) to identify the cognitive and brain processes underlying this development. To do this, this study will have to include healthy subjects, 18 to 95 years, patients with Mild Cognitive Impairment (MCI) and ...
We are studying subjects with mild to moderate Alzheimer's disease who have been on a stable dose of any cholinesterase inhibitor [donepezil (Aricept), rivastigmine (Exelon), or galantamine (Razadyne)] for at least 3 months, and have not previously taken memantine (Namenda). This is an open-label study, with magnetic resonance spectroscopy (MRS) as the primary outcome measure, along with neuropsychological testing, and optional lumbar puncture, evaluating patients on their stab...
Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.
In a previous study, NCT00582127, two age-matched cohorts, one clinically diagnosed with mild Alzheimer's disease and the other healthy controls, were tested with a hand-held EEG/ERP system to determine if the cohorts could be discriminated using the EEG/ERP measures. This study proposes to retest the AD cohort 18-60 months after their first test to characterize the change in EEG/ERP measures correlated with the longitudinal change in neuropsychological testing.
This is a multi-center study that has three cohorts: 1) cognitive normal cohort (CN), 2) Alzheimer's disease cohort (AD) and 3) vascular cognitive impairment cohort (VCI). The goal of this study is to understand the risk factors of AD and VCI and to identify high risk patients for early intervention. It will collect demographic information, family history, medical history, neuropsychological tests, imaging studies and biological samples through standard and uniform procedures.
The purpose of this study is to evaluate the efficacy of NKO™ softgels in reducing decline of global cognitive function as measured by the Neuropsychological Test Battery (NTB), in patients diagnosed with early stage Alzheimer's disease when compared to fish oil and a placebo after 24 weeks of treatment.
This was a 52-week, multicentric, phase II, pilot study conducted in 40 subjects with early-onset alzheimer's disease (AD) to evaluate safety, tolerability and clinical efficacy of interferon (IFN) beta-1a [Rebif 22 mcg, three times per week (tiw)] in the treatment of AD by comparing the neuropsychological performance changes into placebo and treatment arms from screening/baseline to 52 week.
The objective of this study is therefore to compare the results obtained with these two screening tests, using as gold standard the results obtained by the battery of neuropsychological reference tests.
The Atlas of Retinal Imaging in Alzheimer's (ARIAS) study is a 5-year study examining the natural history of retinal imaging biomarkers associated with disease risk, disease burden, and disease progression in Alzheimer's disease (AD). The objective of this project is to create a 'gold standard' reference database of structural anatomic and functional imaging of the retina, in order to enable the identification and development of both sensitive and reliable markers of AD risk an...
The goal of this proposal is to collect normative data from a sample of ethnically diverse Florida elders on a brief, standardized neuropsychological test battery . The norms collected in this multi-cultural dataset will provide appropriate corrections for demographic and sociocultural variables that contribute to performance variance on neuropsychological tests. By accounting for these variables, the normative corrections will improve specificity and eliminate disparities in d...
The purpose of this study is to identify association between cerebrospinal fluid Alzheimer's Disease's neurodegenerescence biomarkers (tau, ptau, Aß40 and Aß1-42) and occurrence of cognitive deficits in older patients with bipolar disorders.
The purpose of this study is to see if an intense two-week long cognitive training program helps the thinking ability of adults with very mild Alzheimer Disease. We anticipate that scores on clinical cognitive tests will be better after the training.
