Comparing Detection of Alzheimer's and Vascular Disease-Related Cognitive Impairment With Brief Cognitive Screens.

Objectives: The study compared the accuracy of the Mini-Mental State Examination (MMSE) with its modified version (3MS) in distinguishing healthy older adults from adults with cognitive impairment due to suspected Alzheimer's disease (AD) or vascular disease (VaD). Method: Participants were 98 veterans who underwent comprehensive neuropsychological evaluation due to concern for cognitive decline. Participants were selected via retrospective chart review on the basis of diagnosis. They had diagnoses of mild or major neurocognitive disorder due to suspected AD (N=20), mild or major neurocognitive disorder due to suspected VaD (N=44), or no neurocognitive diagnosis (i.e., healthy adult comparisons; HC, N=34). Results: The 3MS demonstrated superior detection of cognitive impairment. The extent of this enhanced detection was influenced by the suspected etiology of cognitive impairment. The 3MS and MMSE had comparable discrimination of AD and HC. With respect to VaD, the 3MS showed superior discriminability compared to the MMSE. Conclusions: Overall, results support the adoption of the 3MS over that of the MMSE. The 3MS is a superior (and free) tool for detecting cognitive impairment in geriatric populations. Its use is recommended for first-line screening of cognitive symptoms in older adult populations, especially those with concern for VaD.

Neuropsychology of COVID-19: Anticipated cognitive and mental health outcomes.

OBJECTIVE: Discuss anticipated patterns of cognitive and emotional dysfunction, prognostic indicators, and treatment considerations based on review of (a) neuroinvasive properties of prior human coronaviruses and (b) extensively researched disorders which share similar neurological mechanisms. METHOD: A web-based comprehensive search of peer-reviewed journals was conducted based on a variety of key terms (and variants of) including coronavirus, neuroinvasion, cognitive dysfunction, viral pandemics, respiratory illness, critical illness, and metabolic disease. Articles were chosen based on relevance to the current topic and ability to provide unique thematic information. Historical articles were included if these added scientific merit to recent literature. Review of information in widely disseminated news articles was followed-up with direct review of cited scientific literature. Databases searched included Google Scholar, PubMed, and Ovid Medline. RESULTS: Based on neuroinvasive properties of prior coronaviruses and existing research on similar neurophysiological conditions with detrimental cognitive effects, COVID-19-especially those with severe symptoms-are at risk for cognitive decline and significant psychiatric/behavioral sequela. CONCLUSIONS: There are few studies examining cognitive outcomes in COVID-19. This review argues that neuropsychological sequelae are to be expected in patients with COVID-19. Considerations for clinicians working with this unique population are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Unmet Rehabilitation Needs Indirectly Influence Life Satisfaction 5 Years After Traumatic Brain Injury: A Veterans Affairs TBI Model Systems Study.

OBJECTIVE: To describe the association between unmet rehabilitation needs and life satisfaction 5 years after traumatic brain injury (TBI). DESIGN: Prospective observational cohort. SETTING: Five Veterans Affairs (VA) Polytrauma Rehabilitation Centers. PARTICIPANTS: VA TBI Model Systems participants (N=301); 95% male; 77% white; average age, 39±14y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Satisfaction With Life Scale (SWLS). RESULTS: Average SWLS score was 22±8. Univariable analyses demonstrated several statistically significant predictors of life satisfaction, including employment status, participation, psychiatric symptom severity, past year mental health treatment, and total number of unmet rehabilitation needs (all P<.05). Multivariable analyses revealed that depression and participation were each associated with life satisfaction. An ad hoc mediation model suggested that unmet rehabilitation needs total was indirectly related to life satisfaction. Total unmet rehabilitation needs ranged from 0-21 (mean, 2.0±3.4). Correlational analyses showed that 14 of the 21 unmet rehabilitation needs were associated with life satisfaction. CONCLUSIONS: Findings support the need for rehabilitation engagement in later stages of TBI recovery. Ongoing assessment of and intervention for unmet rehabilitation needs in the chronic phase of recovery have the potential to mitigate decline in life satisfaction.
