Review
Factors associated with initiation of advance care planning in dementia: a systematic review.
Planning ahead may be particularly relevant in dementia considering patients' cognitive decline and difficulty to predict the course of the dementia. ⋯ Professional caregivers may initiate ACP early if strategies carefully consider timing and family and patient receptiveness or reluctance, and are family and patient-centered. Interventions should address the complexity of interrelated system and personal factors affecting initiation of ACP.

Review Meta Analysis
Efficacy and safety of donepezil, galantamine, rivastigmine, and memantine for the treatment of Alzheimer's disease: a systematic review and meta-analysis.
The role of currently available drugs for Alzheimer's disease (AD) has been controversial, with some national formularies restricting their use, and health economists questioning whether the small clinical effects are economically worthwhile. ⋯ Cholinesterase inhibitors and memantine are able to stabilize or slow decline in cognition, function, behavior, and global change.

Alzheimer's disease (AD) is a major social and clinical burden in the elderly, affecting 5% of people aged over 65 and 20% aged over 80. Despite improved management, a cure has not been found and hence analysis of predisposing factors to identify preventive strategies has become increasingly important. Surgery and anesthesia have been proposed to increase the incidence of post-operative cognitive decline (POCD) and AD. ⋯ Therapeutic success is, however, often not achieved, since these treatment methods do not address the ongoing neuroinflammatory processes and hence novel therapeutic and protective strategies are urgently needed. This review provides an insight into the current understanding of age-related cognitive impairment post-surgery and reflects on novel markers of AD pathogeneses exploring their use as targets for treatment. It gives a summary of recent efforts in preventing and treating POCD or AD with regards to the choice and depth of anesthesia, surgical strategy, and peri-operative medication, and discusses the mechanism of action and therapeutic prospects of novel agents.

Mitochondria are essential cytoplasmic organelles, critical for cell survival and death. Recent mitochondrial research revealed that mitochondrial dynamics-the balance of fission and fusion in normal mitochondrial dynamics--is an important cellular mechanism in eukaryotic cell and is involved in the maintenance of mitochondrial morphology, structure, number, distribution, and function. ⋯ Attempts have been made to develop molecules to reduce mitochondrial fission while maintaining normal mitochondrial fusion and function in those diseases that involve excessive mitochondrial fission. This review article discusses mechanisms of mitochondrial fission in normal and diseased states of mammalian cells and discusses research aimed at developing therapies, such as Mdivi, Dynasore and P110, to prevent or to inhibit excessive mitochondrial fission.

Review
Influence of anesthetics on Alzheimer's disease: biophysical, animal model, and clinical reports.
Since the finding in the 1880 s that elderly patients may experience cognitive decline following surgery, the search for an understanding of this phenomenon has been underway. In the last decade, evidence from biophysical (light scattering and nuclear magnetic resonance), in vitro, in vivo animal studies, retrospective evaluations of human registries, and recently prospective randomized trials have explored the idea that various anesthetic agents play a role in this phenomenon by interacting with the biochemical mechanisms that are also responsible for the development of Alzheimer's disease. In the current review, we examine the evidence available and conclude that there is significant evidence to suggest an important role for this mechanism.
