Ethical issues in early diagnosis and prevention of Alzheimer disease.
Ethical issues in early diagnosis and prevention of Alzheimer disease. Dialogues Clin Neurosci. 2019 Mar;21(1):101-108 Authors: Whitehouse PJ Abstract This paper considers ethical issues related to early diagnosis and all forms of prevention of Alzheimer disease and related conditions. It offers a critical view of the current state of scientific, clinical, and social responses to the growing number of older people with cognitive challenges, and suggests how priorities going forward should be different from those receiving most attention today. We begin with a review of global policy efforts, consider the fundamental goals of prevention, examine issues surrounding early diagnosis, explore more deeply values associated with efforts to prevent age associated cognitive decline, and conclude by considering often unexplored ethical issues that contextualize the field and should influence our approaches to the future.

DEMENTIA is a progressive neurological condition that mainly affects people over the of 65, although it is not a natural part of ageing. Spotting the early warning signs is key to maintaining quality of life for as long as possible. A recent study suggests that Alzheimer ’s disease, the most common form of dementia, can be signalled by a change in your eyes.

METHODS: Randomized, double-blind, 4-week trial of suvorexant 10 mg (could be increased to 20 mg based on clinical response) or placebo in patients who met clinical diagnostic criteria for both probable AD dementia and insomnia. Sleep was assessed by overnight polysomnography in a sleep laboratory. The primar...

ConclusionThese results demonstrate that vortioxetine may improve cognitive impairment in 5 ×FAD mice. The role in cognitive improvement may be related to the beneficial effects of vortioxetine on synaptic function.
CONCLUSIONS: ¹⁸F-FC119S PET provides high sensitivity and specificity in detecting AD and therefore may be considered a useful diagnostic tool for AD. PMID: 31942769 [PubMed]

In the present study, we sought to investigate whether defective mitophagy is tightly related to amyloid-β (Aβ)-induced mitochondrial dysfunction.Main methodsImmunofluorescence, western blot and transmission electron microscopy were used to examine mitophagy. Mitochondrial membrane potential was assessed using the JC-1 dye. Mitochondrial ROS was detected using Mit...
