This trial will determine the pharmacokinetics of Posiphen® in both plasma and CSF after a 10-day treatment period with Posiphen® in subjects with amnestic MCI. The effects of this treatment on biomarkers will also be determined in CSF, whole blood, and plasma or serum as primary pharmacodynamic (PD) objectives.
Control: Uncontrolled, Endpoint Classification: Pharmacokinetics/Dynamics Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

This study will use two doses of rivastigmine transdermal patch (5cm2, 10cm2) to establish the feasibility of 2 switch schedules (with transdermal patch one-step dose titration or without ...
This is a prospective, 26-week, open-label, single-arm multi-center pilot study. Eligible patients will receive open-label treatment with rivastigmine capsules plus memantine tablets as ad...

A dose ranging study to evaluate the safety, tolerability and efficacy of arformoterol (given once or twice a day) in subjects with COPD.
Neuroimaging modalities can measure different aspects of the disease process in Alzheimer's disease, although the relationship between these modalities is unclear.
Chronic neuroinflammation has been implicated in Alzheimer's disease (AD) pathology.
Exploring the role of Alzheimer's disease (AD) implicated pathways in the predementia phase may provide new insight for preventive and clinical trials targeting disease specific pathways.
Cortical mean diffusivity (MD) and free water (FW) changes are proposed biomarkers for Alzheimer's disease (AD).
The clinical benefit of memantine for Alzheimer's disease (AD) remains inconclusive.
An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. Most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.
One of several acid phosphatases in humans, other mammals, plants, and a few prokaryotes. The protein fold of tartrate-resistant acid phosphatase (TRAP) resembles that of the catalytic domain of plant purple acid phosphatase and other serine/threonine-protein phosphatases that also contain a metallophosphoesterase domain. One gene produces the various forms which include purple acid phosphatases from spleen and other tissues. Tartrate-resistant acid phosphatase is a biomarker for pathological states in which it is over-expressed. Such conditions include GAUCHER DISEASE; HODGKIN DISEASE; BONE RESORPTION; and NEOPLASM METASTASIS.
Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.
Vaccines or candidate vaccines used to prevent or treat ALZHEIMER DISEASE.
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.

Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
