The study hypothesizes that donepezil will have a positive impact on brain blood flow deficits in subjects with memory deficits and/or mild dementia and that improvements in brain blood flow will be accompanied by improvements in memory.

Primary Aim To determine whether; - Donepezil is significantly better than placebo in the management of agitation in Alzheimer's Disease that has not responded to, or is in...
This 4 arm study will assess the efficacy and safety of RO5313534 (MEM3454) versus placebo added to donepezil, in patients with mild to moderate Alzheimer's disease. Following a screening ...
This study aims to determine whether the Cogstate testing battery can detect improvements in cognitive function in participants with mild AD. The primary hypothesis is that the standard de...
The purpose of the study is to examine patterns of brain activity in people who are at risk for memory problems (e.g., Alzheimer's disease or dementia)before and after the medication donep...
This study will evaluate the safety and tolerability of donepezil in treatment of AD patients in China, and also investigate the relationship between Apo-E gene type with adverse events of...
Currently, five pharmacotherapeutic options are available to treat Alzheimer's disease: memantine; the three cholinesterase inhibitors donepezil, galantamine, and rivastigmine; and combination treatme...
Alzheimer's disease (AD) is one of the most common neurodegenerative disorders in elderly people. Considering the multifactorial nature of AD, the concept of multi-target-directed ligands (MTDLs) has ...
This study aimed to establish a non-linear mixed effects model to quantitatively analyze the placebo responses of neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD).
To evaluate the efficacy of oral Chinese medicine (CM) in comparison with donepezil, a cholinesterase inhibitor (ChEI), for the treatment of Alzheimer's disease (AD).
The discovery of acetylcholine and acetylcholinesterase provided the first insight into the intricacies of chemical signal transduc-tion and neuronal communication. Further elucidation of the underlyi...
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 carbamate-derived reversible CHOLINESTERASE INHIBITOR that is selective for the CENTRAL NERVOUS SYSTEM and is used for the treatment of DEMENTIA in ALZHEIMER DISEASE and PARKINSON DISEASE.
A biochemical phenomenon in which misfolded proteins aggregate either intra- or extracellularly. Triggered by factors such as MUTATION, POST-TRANSLATIONAL MODIFICATIONS, and environmental stress, it is generally associated with ALZHEIMER DISEASE; PARKINSON DISEASE; HUNTINGTON DISEASE; and TYPE 2 DIABETES MELLITUS.
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...
