Active clinical trials for "Alzheimer Disease"

To investigate the safety of deep brain stimulation in the treatment of severe Alzheimer's disease (AD); to investigate the effectiveness of deep brain stimulation in the treatment of severe AD, i.e., effects of deep brain stimulation on cognitive function in patients with severe AD and dementia grading; to investigate the effects of deep brain stimulation on cerebral glucose metabolism in patients with severe AD.

This 3-phase research plan to employ Behavioral and Environmental Sensing and Intervention (BESI) will overcome the fundamental scientific barriers to realizing prediction of agitation episodes and detection early stages of dementia related agitation. The goal of which is empowering caregivers to intervene early and ultimately reduce agitation, thus reducing caregiver burden and extending aging-in-place and improving the associated quality-of-life and cost benefits.

The Evidence Amyloid Study EEG (EASE) establishes an open-label, longitudinal cohort study to measure of neurological functioning during the onset and progression of cognitive decline in preclinical Alzheimer's patients using quantitative electroencephalography (qEEG) measures (P300, P50, and reaction time). Participants will be scanned using the ElectroCap (FDA Class II) and/or the WAVi headset with the WAVi EEG P300/P50 system, along with the structured clinical interviews and assessments for baseline screening or mild cognitive impairment which are standard of care.

In this study, the investigators will be looking at results of tests of memory and thinking and daily activities in a group of people without known chronic kidney disease (CKD) , and a group of CKD patients, and follow the participants for up to four more years, including after the participants start dialysis or receive a transplant. The investigators are doing this study to compare how often memory loss, confusion and difficulty with daily activities occur in those without and those with CKD. Additionally, the investigators are doing this study to identify risk factors for memory and thinking problems in CKD patients. The information received through the NDI will be utilized to help track our study population and help provide useful information regarding cause of death of those in our study.

The purpose of this research is to compare the effectiveness of a continuous monitoring system to assess Activities of Daily Living (ADLs) over time compared to the traditional assessments used by medical professionals as Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD) progresses.

Correlation of musicality, brain atrophy in brain areas relevant for music processing and the stage of Alzheimer´s disease.

The most common symptoms associated to senile dementia disease are confusion about schedules, hyperactivity... In this sense, these patients have frequently poor nutrition, resulting in malnutrition problems or malnutrition high risk.

The purpose of the study is to compare the concentrations of Vitamin B1 (thiamine), Vitamin B6 (pyridoxal-5-phosphate), folate, Vitamin B12 (cobalamin), Vitamin C (ascorbic acid), Vitamin A (retinol), Vitamin E (alfa-tocopherol), homocystein, uric acid, F2 8-α-isoprostane, 8-deoxyguanosine, retinoids, tau-protein and β-amyloid in spinal fluid, metabolomics, proteomics, m-RNA for DNA repair enzymes and DNA in patients who suffer from mild cognitive impairment (MCI) or mild dementia of Alzheimers type, with healthy controls. A second aim is to explore the association between vitamin and nutrient reductions, if any, and cognitive function as well as vascular score and possible changes in the MRI.

The purpose of this study is to determine response to pain in Alzheimer's disease.We plan to study the effect of diffuse noxious inhibitory controls(counterirritation phenomenon)and the autonomic nervous system reaction(reflected by the heart rate) in Alzheimer's disease. The study's hypothesis is that pain perception and autonomic nervous system reaction are altered in Alzheimer's disease.

The purpose of this study is to determine whether asymptomatic older individuals with high amyloid burden will subsequently manifest cognitive impairment and eventually progress to clinical Alzheimer's Disease (AD).
