Filter by:The investigators explore the presence of AD factors beta-amyloid and tau in CSF and plasma to verify AD diagnosis in patients with acute hip fracture. Clinical dementia test is performed prior to operation. Blood samples and CSF samples are collected at surgery and blood samples are collected postoperatively at intervals. Mortality is assessed at 30 days, 3 months and 1 year. Morbidity is assessed at , 3 months and >1 year. Neuromarkers specifically addressing the inflammatory component are to be analyzed and correlated to outcome together with AD markers, as above.
A total of 200 home dwelling participants, who fulfil the inclusion criteria, Alzheimer's disease, will be recruited from three hospitals in Norway. The intervention is based on a standardized manual, and consists of 11 weekly one-hour sessions, which are organized into six thematic modules. The content of each session is specified by a treatment manual, which additionally consists of worksheets, suggestions for homework in between sessions and letters to the caregivers (the German manual: Werheid & Thöne-Otto, 2010; the Norwegian manual: Ulstein, Gordner & Tonga, not published). The treatment will be conducted by experienced health staff (nurses, psychologist, doctors) with formal training in Cognitive Behavioural Therapy, and knowledge about Alzheimer's Disease. Furthermore, the health staff will be familiarised with the manual before study inception, participate in a two-day training seminar and will regularly be supervised. The control condition will be offered treatment as usual at the participating the memory clinics. The hypothesis is that the participants in the intervention group will report less depression and increased self efficacy as compared with the control group. We conducted a pilot study with 10 patients, 5 in each group, from March to June 2013 to examine the feasibility of the study protocol and do want to include these patients in the study population.
This study will examine the hypothesis that changes in the cognition (i.e. thinking and memory) after anesthesia and surgery are correlated with changes in markers of Alzheimers Disease in the fluid around the brain and spinal cord (i.e. cerebrospinal fluid, or CSF), and/or changes in brain connectivity. The investigators will also examine whether different types of anesthesia have different effects on these CSF markers of Alzheimers disease, or different effects on thinking and memory after anesthesia and surgery, or differential effects on the correlation between cognitive changes and CSF marker changes.
The overall objective of the study is to assess the feasibility of implementing a quantitative process of florbetapir F 18 scan interpretation. The hypothesis is that the use of quantitative analysis will increase the accuracy of florbetapir F 18 scan interpretation.
The purpose of this study is to assess the safety, tolerability, biomarker, cognitive and clinical efficacy of investigational products in participants with an Alzheimer's disease-causing mutation by determining if treatment with the study drug slows the rate of progression of cognitive/clinical impairment or improves disease-related biomarkers.

Alzheimers disease (AD) is the most common course of cognitive decline and thereby the course of more than half of all cases of dementia. A proper AD diagnosis is rested on a number of examinations and tests, which combined can make AD diagnosis likely. But no single test or examination can unambiguous determine whether the patient has AD or not. Comparatively no examination or test can with accuracy predict whether a healthy person or a person with only mild cognitive (MCI)impairment in time will evolve AD. Quantitative Electroencephalography (qEEG), cerebrospinal fluid (CSF) biomarkers, linear CT analyses and Timed Up and Go - Dual Task (TUG-DT) are relatively inexpensive and and widely available diagnostic methods, which have the potential to diagnose AD at an early stage in a reliable accurate way. But they also have the potential to predict which patients diagnosed with MCI have particular risk of developing dementia. The purpose of the study is to investigate the relations between qEEG, CSF biomarkers, CT analyses and TUG-DT outcome and clinical features in healthy persons as well as patients with MCI and AD Furthermore to investigate whether qEEG or CSF biomarkers can predict which patients with MCI will in time evolve AD.
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.
Today Alzheimers disease can not be cured. Animal experiments have shown that the hormone GLP-1 can improve memory in Alzheimer-prone mice. The investigators hypothesis is that a 6-month treatment with the GLP-1 receptor stimulating drug liraglutide will reduce the intracerebral amyloid deposition in the central nervous system (CNS) in patients with Alzheimer's disease (AD) and thereby reduce the clinical symptoms of the disease.
