“…These results are different from previous research examining the diagnostic accuracy of other language versions of the Qmci, especially the English version, which show that the Qmci screen is more accurate in discriminating MCI (equivalent of PSCIND) from both normal controls and dementia than the MoCA and the MMSE (17)(18)(19)(20). These studies also generally show that the MMSE is less accurate than both the MoCA and Qmci screen (15). The reasons for why this study differs from others is most likely related to its very small sample size.…”

“…The Quick mild cognitive impairment (Qmci) screen is a new, short cognitive screening instrument originally designed to identify mild cognitive impairment (MCI), which is highly accurate in differentiating between normal cognitive function, subjective cognitive disorders, MCI and early dementia (15,16). The Qmci screen is more accurate than MMSE in detecting early cognitive changes (17)(18)(19) and when compared to the MoCA, it has similar accuracy and better specificity but a shorter administration time (20)(21)(22).…”

Background: Screening for post-stroke cognitive impairment (PSCI) is necessary because stroke increases the incidence of and accelerates premorbid cognitive decline. The Quick Mild Cognitive Impairment (Qmci) screen is a short, reliable and accurate cognitive screening instrument but is not yet validated in PSCI. We compared the diagnostic accuracy of a Chinese version of the Qmci screen (Qmci-CN) compared with the widely-used Chinese versions of the Montreal Cognitive Assessment (MoCA-CN) and Mini-Mental State Examination (MMSE-CN).Methods: We recruited 34 patients who had recovered from a stroke in rehabilitation unit clinics in 2 university hospitals in China: 11 with post-stroke dementia (PSD), 15 with post-stroke cognitive impairment no dementia (PSCIND), and 8 with normal cognition (NC). Classification was made based on clinician assessment supported by a neuropsychological battery, independent of the screening test scores. The Qmci-CN, MoCA-CN, and MMSE-CN screens were administered randomly by a trained rater, blind to the diagnosis.Results: The mean age of the sample was 63 ± 13 years and 61.8% were male. The Qmci-CN had statistically similar diagnostic accuracy in differentiating PSD from NC, an area under the curve (AUC) of 0.94 compared to 0.99 for the MoCA-CN (p = 0.237) and 0.99 for the MMSE-CN (p = 0.293). The Qmci-CN (AUC 0.91), MoCA-CN (AUC 0.94), and MMSE-CN (AUC 0.79) also had statistically similar accuracy in separating PSD from PSCIND. The MoCA-CN more accurately distinguished between PSCIND and normal cognition than the Qmci-CN (p = 0.015). Compared to the MoCA-CN, the administration times of the Qmci-CN (329s vs. 611s, respectively, p < 0.0001) and MMSE-CN (280 vs. 611s, respectively, p < 0.0001) were significantly shorter.Conclusion: The Qmci-CN is accurate in identifying PSD and separating PSD from PSCIND in patients post-stroke following rehabilitation and is comparable to the widely-used MoCA-CN, albeit with a significantly shorter administration time. The Qmci-CN had relatively poor accuracy in identifying PSCIND from NC and hence may lack accuracy for certain subgroups. However, given the small sample size, the study is under-powered to show superiority of one instrument over another. Further study is needed to confirm these findings in a larger sample size and in other settings (countries and languages).

“…A series of 5 neurocognitive assessments were selected to correlate with the fMRI cognitive activation tasks. Two were cognitive screening tests: Modified Mini‐Mental State Examination 92 (3MS) and Quick Mild Cognitive Impairment 93,94 (QMCI), and 3 were specific standardised neuropsychological assessments: Wechsler Adult Intelligence Scale—4th Edition (WAIS‐IV) Digit Span Task 95 (DST); Hayling Sentence Completion 96 (HSC) Test; and Trail Making Test 97,98 (TMT).…”

Background The implications of oral rehabilitation after tooth loss require further investigation. Objectives To conduct a pilot study to investigate: (a) changes in masticatory performance with progressive oral implant rehabilitation (POR); (b) association between POR and neurocognitive function using functional magnetic resonance imaging (fMRI); and (c) oral health‐related quality of life (OHQoL) outcomes. Methods Four completely edentulous patients (mean age: 73 ± 1.4 years) participated. Each received new complete removable dental prostheses (RDPs) transitioned to mandibular two implant‐retained RDPs (IR‐RDP). Assessments were performed at 4 time points for neurocognitive skills, fMRI with functional tasks (jaw clenching, working memory and sustained attention, inhibition), masticatory performance with colour‐changing gum and OHQoL. Assessments were performed with new complete RDPs (T0 as baseline data) and IR‐RDPs at 1 week (T1), 6 weeks (T2) and 12 months (T3) post‐insertion. Data analyses were based on intra‐patient and inter‐patient results. Results Masticatory performance and QoL improved with an IR‐RDP at each time point. FMRI jaw clenching sensory and motor cortical activity decreased at T1, with motor cortical activity increasing to T0 levels at T2. For cognitive fMRI activation tasks, cortical activity decreased from T0 to T1 across all regions of interests (ROI) and increased at T2 throughout the cognitive brain regions. Neurocognitive skills declined at T1, followed by improvement to or beyond T0 levels at T2. Conclusion Improvements in masticatory performance and OHQoL occurred from complete RDPs to IR‐RDP. Prosthetic adaptation was associated with neurocognitive changes to pre‐insertion activity levels or greater after 6 weeks. These pilot data suggest both behavioural and neural associations between POR and cognition; however, larger study numbers are required.

“…LM is a brief test of verbal recall for a short descriptive story; in this study the immediate version (within 30 s) was used. It has 15 items and is scored on a 30-point scale with two points given for every correct answer [32]. Administration takes less than one minute and alternate validated versions are available [33].…”

Although there is a high prevalence of delirium and cognitive impairment among hospitalised older adults, short, reliable cognitive measures are rarely used to monitor cognition and potentially alert healthcare professionals to early changes that might signal delirium. We evaluated the reliability, responsiveness, and feasibility of logical memory (LM), immediate verbal recall of a short story, compared to brief tests of attention as a bedside “cognitive vital sign” (CVS). Trained nursing staff performed twice-daily cognitive assessments on 84 clinically stable inpatients in two geriatric units over 3–5 consecutive days using LM and short tests of attention and orientation including months of the year backwards. Scores were compared to those of an expert rater. Inter-rater reliability was excellent with correlation coefficients for LM increasing from r = 0.87 on day 1 to r = 0.97 by day 4 (p < 0.0001). A diurnal fluctuation of two points from a total of 30 was deemed acceptable in clinically stable patients. LM scores were statistically similar (p = 0.98) with repeated testing (suggesting no learning effect). All nurses reported that LM was feasible to score routinely. LM is a reliable measure of cognition showing diurnal variation but minimal learning effects. Further study is required to define the properties of an ideal CVS test, though LM may satisfy these.
