Summary: This study compared diagnostic rates and clinical predictors between NIA-AA criteria and DSM-5 criteria, finding that discrepancies were more likely in individuals with a history of MDD or carrying at least one ApoE4 allele. Detailed neuropsychological testing and NIA-AA criteria identified a greater prevalence of cognitive impairment compared to DSM-5 criteria and the Montreal Cognitive Assessment.

Summary: This study aimed to evaluate the accuracy of self-reported and informant-reported subjective cognitive complaints and their relation to neuropsychological function in different diagnostic groups. The results showed that self-reported subjective cognitive complaints were not related to neuropsychological function in cognitively unimpaired and mild cognitive impairment populations, while informant-reported complaints were related to neuropsychological tests in the dementia population. Therefore, incorporating informant-reported subjective cognitive complaints, along with considering individual's anxiety and depressive status, is crucial in clinical practice for assessing cognitive statuses.

Summary: Cognitive impairment is a serious condition associated with aging and disruption of inflammation and innate immunity. Recent studies have shown that the innate immune system is prevalent in patients with Alzheimer's disease, and peripheral neutrophil markers can predict a decline in cognitive function in patients with mild cognitive impairment. Furthermore, altered levels of pro-inflammatory interleukins have been reported in patients with mild cognitive impairment, potentially playing a role in the progression from early cognitive impairment to dementia.

Summary: The study found that VR training has moderate to large effects on cognitive abilities in patients with MCI and dementia, improving global cognition, attention, memory, and construction and motor performance in MCI patients, as well as global cognition, memory, and executive function in dementia patients. Moderators such as immersion and training type significantly influence the effects of VR training.

Summary: Mild cognitive impairment (MCI) is a clinical condition with a high risk of progressing to dementia. Early diagnosis and intervention at the MCI stage are considered critical strategies in disease management. Lack of consensus on guidelines for routine screening of MCI leads to a considerable number of undiagnosed patients in the community.

Summary: The study examined the rate of reversion from mild cognitive impairment to normal cognition in a unidirectional manner within the Alzheimer's disease continuum. There were both non-modifiable factors (age, socioeconomic status, apolipoprotein E) and modifiable factors (cognitive training, absence of affective symptoms) associated with reversion. The likelihood of progression from MCI to dementia was found to be similar to that of reversion from MCI to NC.

Summary: The study found that participants with higher consumption levels of rice, legumes, fresh vegetables, fresh fruit, meat, and nuts tended to have higher global cognitive function scores and lower odds of mild cognitive impairment (MCI). Participants with a medium consumption level of beef or mutton had 57% higher odds of amnestic MCI-single domain (aMCI-SD), whereas they had 50% lower odds of non-amnestic MCI-multiple domain (naMCI-MD). Significant heterogeneity of associations between diet and MCI subtypes was observed among Chinese adults aged over 55.

Summary: This study examined the impact of mild behavioral impairment (MBI) on cognitive performance among cognitively healthy older adults and those with mild cognitive impairment (MCI). The results showed that individuals with MBI performed worse on tasks of attention, episodic memory, executive function, language, and processing speed, and exhibited greater decline over time. The presence of MBI was also associated with poorer performance on tasks of visuospatial ability, executive function, and processing speed among individuals with MCI.

Summary: This study found that both self-reported and informant-reported subjective cognitive complaints are associated with an increased risk of transitioning from cognitively unimpaired to mild cognitive impairment and/or dementia. The association appears to be stronger and more stable for informant-reported data, providing important information for distinguishing between normal aging and clinical states.

Summary: This study examined longitudinal changes in cognitive and physical function, as well as the associations between these changes and falls in people with and without mild cognitive impairment (MCI). The results showed that the MCI and cognitively fluctuating groups experienced declines in cognitive function, while the cognitively normal group did not. The MCI group had worse physical function at baseline but similar decline over time compared to other groups. Decline in global cognitive function and sensorimotor performance were associated with multiple falls in the cognitively normal group, and decline in mobility was associated with falls in the entire sample. Therefore, exercise should be recommended for maintaining physical function in older adults, and interventions aimed at mitigating cognitive decline should be encouraged for people with MCI.

Summary: This study scoped the international literature on registered nurses delegating care to unlicenced workers, identified gaps, and reflected on the evidence's relevance to nursing in multiple contexts. The review highlighted three models of delegation: direct, indirect, and a combination of both. It found that direct delegation mainly occurred in acute contexts, but the threshold for delegation decrease was unclear. However, there is a lack of studies focusing on patient outcomes and the legal and logistical implications of delegation practices in the literature.

Summary: This study aims to understand the perceptions of dementia symptoms, help-seeking and support in the Australian Arabic-speaking community. By conducting qualitative interviews, seven themes were identified. Dementia was described as confusion and memory loss symptoms. Barriers to help-seeking and support included cultural norms, lack of knowledge on where to seek help, and fear of community judgement. Building trust through culturally appropriate support and educating the community are two ways to facilitate help-seeking and support.
