Alzheimer's disease is the most common form of dementia and is characterized by a progressive loss of cognitive functions. As the result of predicted demographic changes over the next decades, Alzheimer's disease is expected to be one of the most pressing medical and social challenges facing our generation. Current treatment strategies remain symptomatic. However, new approaches have shown promise in clinical trials, particularly in patients with only mild or moderate symptoms. Early detection of Alzheimer's disease is therefore of critical importance. Currently available diagnostic approaches (such as protein analysis in cerebrospinal fluid or neuroimaging), however, are expensive and invasive and therefore unsuitable for the screening of a large population. Consequently, Alzheimer's disease is generally diagnosed too late for effective intervention. MicroRNAs-readily measurable in biofluids and resistant to freeze-thaw and pH changes, have shown encouraging diagnostic potential in Alzheimer's disease. Several studies have attempted to correlate changes of specific microRNAs to disease progression using different approaches and profiling platforms including micro-arrays, RNA sequencing, and qPCR-based systems. In the present book chapter, we will describe the different steps involved in how to determine the microRNA profile in plasma samples from patients using the OpenArray platform.

Alzheimer's disease (AD) is the most common neurodegenerative disease and the early diagnosis and intervention are important for valid treatment of AD. However, there are few biomarkers for the diagno...

The overall goal of the Alzheimer's Disease Neuroimaging Initiative (ADNI) is to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI is a multisite, longitudinal, observational stud...
Cerebrospinal fluid (CSF) biomarkers have the potential to improve the diagnostic accuracy of Alzheimer's disease, yet there is a lack of harmonized preanalytical CSF handling protocols.
Agitation is one of the most challenging neuropsychiatric symptoms to treat in Alzheimer's disease and has significant implications for patient and caregiver. A major source of difficulty in identifyi...

MicroRNAs found in cell-free BODY FLUIDS such as SERUM; PLASMA; SALIVA; OR URINE.
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.

A factor associated with the well-being of living organisms that is used as a measure of environmental change and or influence. For example, aldehyde dehydrogenase expression in earthworm tissue is used as an indication of heavy metal pollution in soils. Distinguish from BIOMARKERS.

Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
