Summary: This review examined home/community-based interventions for individuals with mild cognitive impairment/early dementia and found that interventions incorporating visual/written elements, technology-based training, and caregiver support were effective in improving function. Participants simulated Instrumental Activities of Daily Living and cognitive function was assessed using both objective and subjective measures. However, gaps were identified in the literature regarding the inclusion of race/ethnicity and appropriate socioeconomic status measures.

Summary: This study investigated the association between gait speed and qualitative errors on the Clock Drawing Test (CDT) in individuals with mild cognitive impairment (MCI). The results showed that conceptual deficit (CD) type errors were negatively associated with maximum gait speed. This study further supports the clinical importance of qualitative assessments of the CDT.

Summary: The study found that poor social networks are associated with higher risk of declining cognitive function, mild cognitive impairment (MCI), and dementia among older adults, independent of other lifestyle factors, depression, and genetic disposition. Older adults with better social networks have lower risks of cognitive decline and MCI. The study's inclusion of relevant covariates contributes significantly to understanding cognitive aging.

Summary: The study found that older adults with mild behavioral impairment (MBI) performed worse on tasks of executive function, attention, and episodic memory than those without MBI. Additionally, individuals with both MCI and MBI showed significantly poorer performance on episodic memory tasks compared to those with only MCI.

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: Mild cognitive impairment (MCI) is a common non-motor symptom in patients with Parkinson's disease (PD), but lacks consistent diagnostic criteria. Different types of cognitive impairments have different progression rates. This review provides an overview of the diagnostic criteria for PD-MCI and the heterogeneity of patients' cognitive function.

Summary: This study investigates the effects of virtual shopping training on executive function and instrumental activities of daily living (IADL) in patients with mild cognitive impairment (MCI). The results suggest that virtual shopping training may be clinically beneficial in enhancing executive function and IADL in patients with MCI.

Summary: This study investigated white matter microstructural integrity and cognitive correlates of memory awareness in older adults with or without mild cognitive impairment (MCI). While patients with MCI and poor awareness of memory deficits showed lower integrity in certain white matter fibers, the memory awareness deficits in MCI patients could not be solely explained by mnemonic anosognosia.

Summary: This study described seven cases from Brazil of outpatients with mild or moderate COVID-19 who developed subacute cognitive disturbances after recovery. The results suggest that these cognitive symptoms might be related to SARS-CoV-2-induced damage to cortico-subcortical associative pathways, rather than solely due to inflammation and hypoxia.

Summary: Eye movement in response to visual tasks provides insights into the cognitive processes affected in cognitive decline. By analyzing tasks such as anti-saccades and memory guided fixation, individuals with mild cognitive impairment and dementia can be differentiated from cognitively unimpaired individuals. The results of this study suggest that anti-saccade tasks hold promise in clinical practice for professionals working with individuals with cognitive decline.

Summary: Age and worsening attention, but not depression, in MCI patients were independently associated with the progression to dementia in a 6-year follow-up period. Age was identified as an independent risk factor for MCI aggravation, while attention (MoCA) was an independent protective factor for MCI progression.

Summary: The study found that in mild cognitive impairment, the semantic network is preserved but the existing associations are exploited less efficiently during long-term memory search, possibly due to deficits in executive function.

Summary: Cognitive impairment is often accompanied by gait disturbance in patients with Parkinson's disease (PD). This study aimed to investigate the association between gait parameters and mild cognitive impairment (MCI), as well as the correlation between performance on comprehensive neuropsychological tests and gait parameters in PD patients. The results showed that gait velocity and stride length were associated with MCI in PD patients, and these gait parameters were primarily influenced by attention and frontal-executive function.

Summary: The updated definition of sarcopenia by EWGSOP2 includes low muscle mass and quality, as well as poor physical performance as indicative of severe sarcopenia. The study found that individuals with any form of sarcopenia were at a higher risk of disability, with severe sarcopenia increasing the risk further. Grip strength and walking speed were negatively correlated with disability incidence.

Summary: The study aimed to investigate the prevalence of social frailty among older adults in a rural Japanese community and factors associated with social frailty status. The results showed that social frailty is increasing in Japanese rural areas, with social prefrailty potentially being associated with attentional function and GDS-15 scores.

Summary: Subjective cognitive decline (SCD) in older adults is associated with an increased risk of dementia, but the underlying mechanisms are not well understood. This study found that older adults with SCD have more modifiable protective factors against dementia and a lower risk of developing objective cognitive decline. These findings highlight the importance of addressing modifiable factors in preventing dementia.
