Communicating Risk: Developing an “Efficiency Index” for Dementia Screening Tests
Brain Sciences, 2021 Diagnostic and screening tests may have risks such as misdiagnosis, as well as the potential benefits of correct diagnosis. Effective communication of this risk to both clinicians and patients can be problematic.

The reliability of assigning individuals to cognitive states using the Mini Mental-State Examination: a population-based prospective cohort study. [PDF]
, 2011 BACKGROUND: Previous investigations of test re-test reliability of the Mini-Mental State Examination (MMSE) have used correlations and statistics such as Cronbach's α to assess consistency.

Masticatory function and cognitive function
Okajimas Folia Anatomica Japonica, 2010 Recent studies have suggest that masticatory (chewing) function is useful for maintaining neurocognitive function in the elderly. For example, a reduced ability to masticate, such as that resulting from toothlessness or soft-diet feeding, causes learning and memory deficits in aged animals and pathologic changes in the hippocampus.

Slow Is Also Fast: Feedback Delay Affects Anxiety and Outcome Evaluation
Frontiers in Human Neuroscience, 2018 Performance-related feedback plays an important role in improving human being’s adaptive behavior. Using event-related potentials (ERPs), previous studies have associated a particular component, i.e., reward positivity (RewP), with outcome evaluation ...

Determinants of Activity Levels in African Americans With Mild Cognitive Impairment. [PDF]
, 2016 Engaging in cognitive, social, and physical activities may prevent cognitive decline. In a sample of older African Americans with mild cognitive impairment (MCI; N=221), we investigated the cross-sectional relationships between activity levels and ...

Symphony of Well-Being: Harmony Between Neural Variability and Self-Construal
Frontiers in Human Neuroscience, 2021 Both neural activities and psychological processes vary over time. Individuals with interdependent self-construal tend to define themselves and adjust their behaviors to social contexts and others.

Function-Theoretic Explanation and the Search for Neural Mechanisms [PDF]
, 2017 A common kind of explanation in cognitive neuroscience might be called functiontheoretic: with some target cognitive capacity in view, the theorist hypothesizes that the system computes a well-defined function (in the mathematical ...

Circadian rest-activity rhythms predict cognitive function in early Parkinson's disease independently of sleep [PDF]
, 2018 BACKGROUND: Cognitive impairment is a common and debilitating symptom of Parkinson's disease (PD), and its etiology is likely multifactorial. One candidate mechanism is circadian disruption. Although there is evidence of circadian abnormalities in PD, no
