Beta ‐amyloid PET imaging for Alzheimer's dementia diagnosis

Alzheimer's dementia is the most commonly diagnosed dementia. Despite this, diagnosis can be especially complex in certain circumstances. Any additional, novel diagnostic aids can positively add to the diagnostic process, overall accuracy and ultimately to patient care and treatment. Beta ‐amyloid (Aβ) positron emission tomography (PET) imaging is utilised as an important diagnostic tool in NHS dementia research in the UK and worldwide. Aβ PET imaging is now licensed for clinical use in the UK. This review explores the potential for the use of Aβ PET imaging in clinical practice highlighting recent evidence base followed by a discussion of potential benefits in the context of important clinical and practical considerations.

Conclusion: These data suggest that ART exposure is associated with increased levels of Aβ1–42 and Aβ1–40 in the CSF. Also, HAD, but not ANI/MND diagnosis is associated with decreased levels of Aβ1–42 and Aβ1–40 in CSF, potentially suggesting impaired clearance. These data suggest that HIV infection and ART may impact pathogenic mechanisms involving Aβ1–42 and Aβ1–40, but not p-tau.

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

Conclusions: The findings suggest that people with Alzheimer's dementia and their caregivers regard mobility aid use as increasing independence. There is a role for healthcare professionals to be involved in the prescription, provision and training for use of mobility aids among people living with dementia to ensure uptake and safety.IMPLICATIONS FOR REHABILITATIONMobility aid use is regarded as increasing independence by people with Alzheimer's disease and their caregivers.Falls risk associated with mobility aid use was not well known and caregivers perceived mobility aids as a means to reduce falls.Most people do not see...

CONCLUSIONS: Use of HAs is associated with delayed diagnosis of AD, dementia, depression, anxiety, and injurious falls among older adults with HL. Although we have shown an association between use of HAs and reduced risk of physical and mental decline, randomized trials are needed to determine whether, and to what extent, the relationship is causal. The Study in Context: Hearing aids, by reducing cognitive load, can improve brain function in persons with hearing loss 46.7 million Americans have Alzheimer’s Disease brain pathology today, so it’s urgent to prevent or at least delay progression to clinical disea...

DISCUSSION: In the future, managers and employees in acute care hospitals will be able to find a wide range of suggestions in comprehensive guidelines from the iso-Institute on the modular implementation of dementia-sensitive hospitals, which is backed up by tried and tested and effective aids to action, instruments, process descriptions, etc. The guidelines will also be available in the form of a comprehensive list of recommendations.
