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
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.

Apolipoprotein E4 (ApoE4) has been considered to have detrimental effects on the age of onset and progression in Alzheimer's disease. Evidence continues to accumulate regarding the effects of ApoE isoforms in a number of other neurological diseases. ⋯ It further provides evidence of the effect neuroinflammation has in increasing susceptibility to cognitive decline in younger patients. Determining where these diverse diseases intersect and diverge in their relationship to ApoE provides insight into the two-hit mechanism in cognitive decline.

Alzheimer's disease (AD) is a progressive, neurodegenerative disease characterized by an increasing incidence. One of the pathologic processes that underlie this disorder is impairment of brain microvasculature. ⋯ With transcranial ultrasound, the most frequently studied parameters are cerebral blood flow velocities and pulsatility indices, cerebrovascular reserve capacity, and cerebral microembolization. On the basis of current knowledge, we recommend using as a transcranial Doppler sonography screening method of choice the assessment of cerebrovascular reserve capacity with breath-holding test.
