Cognitive impairment and neurocognitive profiles among people living with HIV and HIV-negative individuals older over 50 years: a comparison of IHDS, MMSE and MoCA.

We aimed to examine the l differences in the assessment of neurocognitive impairment (NCI) using cognitive screening tools between PLWH and HIV-negative individuals and further compare the neurocognitive profiles between the two groups. This was baseline evaluation of Pudong HIV Aging Cohort, including 465 people living with HIV (PLWH) and 465 HIV-negative individuals aged over 50 years matched by age (± 3 years), sex and education. NCI was assessed using the Chinese version of Mini-mental State Examination (MMSE), the International HIV Dementia Scale (IHDS) and Beijing version of Montreal Cognitive Assessment (MoCA). In total, 258 (55.5%), 91 (19.6%), 273 (58.7%) of PLWH were classified as having NCI by the IHDS, MMSE and MoCA, compared to 90 (19.4%), 25 (5.4%), 135 (29.0%) of HIV-negative individuals, respectively (p < 0.05); such associations remained significant in multivariable analysis. PLWH showed a larger overlap of NCI detected by IHDS, MMSE, and MoCA. IHDS and MoCA detected almost all of the NCI detected by MMSE. IHDS-motor and psychomotor speeds and MoCA-executive function showed the greatest disparities between two groups. In multivariable analysis, older age and more depressive symptoms were positively associated with NCI regardless of the screening tools or HIV serostatus. PLWH over 50 years old display a higher prevalence of NCI and distinct neurocognitive profiles compared to HIV-negative individuals, despite viral suppression. Given the more considerable overlap in NCI classification in PLWH, it is advisable to choose one screening tool such as IHDS or MoCA to identify those potentially having NCI and then refer to more comprehensive neuropsychological assessment.

The utility of remote cognitive screening tools in identifying cognitive impairment in older surgical patients: An observational cohort study.

STUDY OBJECTIVES: To determine the prevalence of suspected cognitive impairment using the Centers for Disease Control and Prevention (CDC) cognitive question, Ascertain Dementia Eight-item Questionnaire (AD8), Modified Telephone Interview for Cognitive Status (TICS-M), and Telephone Montreal Cognitive Assessment (T-MoCA), the agreement between each tool beyond chance, and the risk factors associated with a positive screen. DESIGN: Multicenter prospective study. SETTING: Remote preoperative assessments. PATIENTS: 307 non-cardiac surgical patients aged ≥65 years. MEASUREMENTS: Prevalence, Cohen's kappa (κ). MAIN RESULTS: The T-MoCA detected the highest prevalence of suspected cognitive impairment (28%), followed by the AD8 (17%), CDC cognitive question (9%), and TICS-M (6%). The four screening tools showed poor agreement beyond chance with one another, with the CDC cognitive question and AD8 approaching the threshold for weak agreement (κ = 0.39). Depression was associated with screening positive on the CDC cognitive question (OR: 2.81; 95% CI: 1.04, 7.68). Obstructive sleep apnea (OSA) (OR: 3.10; 95% CI: 1.26, 7.71) and functional disability (OR: 3.74; 95% CI: 1.34, 11.11) were associated with a positive AD8 screen. Older age (OR: 1.56; 95% CI: 1.01, 2.41), male sex (OR: 3.08; 95% CI: 1.09, 9.40), and higher pain level (OR: 1.21; 95% CI: 1.01, 1.47) were associated with a positive TICS-M screen. Similarly, older age (OR: 1.33; 95% CI: 1.03, 1.73), male sex (OR: 2.02; 95% CI: 1.09, 3.83), and higher pain level (OR: 1.15; 95% CI: 1.02, 1.30) were associated with a positive T-MoCA screen. CONCLUSIONS: The CDC cognitive question, AD8, TICS-M, and T-MoCA were easily implemented during preoperative assessment among older surgical patients. OSA, functional disability, and depression were associated with complaints on the CDC cognitive question and AD8. Older age, male sex, and higher pain level were associated with screening positive on the TICS-M and T-MoCA. Early remote cognitive screening may enhance risk stratification of vulnerable patients.

Rapid cognitive assessment tools for screening of mild cognitive impairment in the preoperative setting: A systematic review and meta-analysis.

IMPORTANCE: Mild cognitive impairment (MCI) is a high-risk precursor to dementia, post-operative delirium, and prolonged hospitalization. There is a need for preoperative rapid cognitive screening tools. STUDY OBJECTIVE: To evaluate the predictive parameters of rapid MCI screening tools in different clinical settings for preoperative application. DESIGN: Systematic review and meta-analyses searching Medline, and other databases from inception to May 26, 2021. The Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines were followed for data curation and quality assessment. Title and abstract screening were conducted independently via Rayyan. Data was curated through a random-effects model and statistical analysis used R-software. SETTING: Community, memory clinic, emergency, long-term care, and in-patient settings. There were no studies in the preoperative setting. PATIENTS: Twenty-three studies with 9973 patients (≥ 60 years old) undergoing rapid MCI screening. INTERVENTION: Rapid (≤ 5 min) MCI screening tools. MEASUREMENTS: Pooled predictive parameters (sensitivity, specificity) of screening tests. MAIN RESULTS: Eighteen screening tools, compared to neuropsychological tests, were identified. The overall prevalence of MCI among the Rapid Cognitive Screen (RCS), Six-item Screener (SIS), Mini-Cog, and Clock Drawing Test (CDT) studies were 24.6%, 28.3%, 40.9%, and 20.7%, respectively. RCS has 82% sensitivity and 79% specificity in detecting MCI. SIS has 61% sensitivity and 89% specificity. Mini-Cog has 52% sensitivity and 80% specificity. CDT has 56% sensitivity and 59% specificity. Seven other index tools had high sensitivities of 97%-82% and specificities of 90%-73% but were studied only once. CONCLUSION: No rapid screening tools had been validated in the surgical population. In other populations, RCS may be a promising screening tool for MCI with stronger sensitivity and specificity than Mini-Cog, SIS, and CDT. CDT alone is ineffective for MCI detection. Further validation in the preoperative setting is required to determine the efficacy of these screening tools.

The usfulness of the SLUMS test for diagnosis of mild cognitive impairment and dementia. / Przydatnosc testu SLUMS w diagnostyce lagodnych zaburzen poznawczych i otepien.

OBJECTIVES: To compare Polish version of the The Saint Louis University Mental Status Examination test (SLUMS) to generally used psychometric screening tools for detecting mild cognitive impairment and dementia. METHODS: The total number of 58 nursing home residents were divided into 3 groups: 1) people showing no symptoms of dementia, 2) people with mild cognitive impairment and 3) people with suspected dementia. The Saint Louis University Mental Status Examination (SLUMS), Mini Mental State Examination (MMSE), Short Test of Mental State (STMS) and Test Your Memory (TYM) were administered for comparison. RESULTS: Mean age was 81.7 ± 8.62. Regarding the education, 37.9% of the sample was educated at the primary school level, 31% completed high school and 22.4 % had higher education. The SLUMS internal consistency was 0.7031. The mean of total SLUMS score was 23.3 in no demented residents, 19.3 among those identified as having cognitive impairments and 13.1 residents with suspected dementia. The statistical analysis illustrated that SLUMS differentiate the dementia residents from those considered as having cognitive impairment (p = 0.01), as well as from non demented participants (p = 0.0001). Moreover, it seems to be useful for detecting mild cognitive impairment in non demented participants (p=0.017), while MMSE does not offer such a possibility (p = 0.51). CONCLUSIONS: The SLUMS is not just another screening tool that can complement the range of existing cognitive tests in Polish clinical practice, but according to statistical analysis it demonstrates superior capabilities in the screening diagnosis compared to the most famous scale used in Poland - MMSE.

A Serious Game for Clinical Assessment of Cognitive Status: Validation Study.

BACKGROUND: We propose the use of serious games to screen for abnormal cognitive status in situations where it may be too costly or impractical to use standard cognitive assessments (eg, emergency departments). If validated, serious games in health care could enable broader availability of efficient and engaging cognitive screening. OBJECTIVE: The objective of this work is to demonstrate the feasibility of a game-based cognitive assessment delivered on tablet technology to a clinical sample and to conduct preliminary validation against standard mental status tools commonly used in elderly populations. METHODS: We carried out a feasibility study in a hospital emergency department to evaluate the use of a serious game by elderly adults (N=146; age: mean 80.59, SD 6.00, range 70-94 years). We correlated game performance against a number of standard assessments, including the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and the Confusion Assessment Method (CAM). RESULTS: After a series of modifications, the game could be used by a wide range of elderly patients in the emergency department demonstrating its feasibility for use with these users. Of 146 patients, 141 (96.6%) consented to participate and played our serious game. Refusals to play the game were typically due to concerns of family members rather than unwillingness of the patient to play the game. Performance on the serious game correlated significantly with the MoCA (r=-.339, P <.001) and MMSE (r=-.558, P <.001), and correlated (point-biserial correlation) with the CAM (r=.565, P <.001) and with other cognitive assessments. CONCLUSIONS: This research demonstrates the feasibility of using serious games in a clinical setting. Further research is required to demonstrate the validity and reliability of game-based assessments for clinical decision making.
