“…In conclusion, the present study demonstrates that Italian alternate MoCA forms show differences in some domain scores, as recently reported in other languages [17]. Since MoCA is particularly suited for detection of MCI [38] and encompasses tasks tapping executive abilities [11], it is important to adopt alternate versions of the test to assess changes in general cognitive abilities over time reliably.…”

Objective. The Montreal Cognitive Assessment (MoCA) is a screening test widely used in clinical practice and suited for detection of Mild Cognitive Impairment. Alternate forms of the MoCA were developed to avoid "learning effect" in serial assessments, and the present study aimed at investigating inter-form parallelism and at providing normative values for the Italian versions of MoCA 2 and 3. Method. Three separate convenience samples were recruited: the first (n= 78) completed three alternate MoCA versions for ascertaining inter-form parallelism; the second (n= 302) and the third (n= 413) samples were administered MoCA 2 or 3 to compute normative data. Results. A three-step procedure complemented by confirmatory factor analysis and a mixed factorial ANOVA suggested that the three MoCA versions are not strictly parallel. Multiple linear regression analysis revealed that age and education significantly influenced MoCA 2 and 3 total scores. No significant effect of sex was found. From the derived linear equation, correction grids for MoCA 2 and 3 raw scores were built and equivalent scores computed. Inferential cutoff for adjusted scores, estimated using a non-parametric technique, were 17.49 for MoCA 2 and 18.34 for MoCA 3. Correlation analysis showed strong correlations of MoCA 2 (r= 0.69, p< .001) and MoCA 3 (r= 0.61, p< .001) adjusted total scores with MMSE adjusted scores. Conclusion. The three MoCA forms are not strictly parallel. Specifically developed normative data must be adopted for using MoCA in serial cognitive assessments for clinical and research studies.

“…16 With the help of Deluxe Multi-Choice Reaction Time Apparatus (Lafayette Instrument Company), tests were conducted on students who also did not reveal significant statistical differences in reaction time. 17 The number of studies on gender differences and lack of sleep and its effects is small and the results are contradictory. However, authors of existing studies on experimental sleep deprivation rarely consider gender as a potential variable.…”

Background: The number of studies on gender differences in psychomotor performance and sleepiness is small and the results are contradictory. The aim of this study was to assess the changes in psychomotor performance, due to 24 h of sleep deprivation in young women and men. Participants: Eighty-nine students (49 women and 40 men) took part in the study. Participants were randomized into two groups: experimental (sleep deprived) and control (non-sleep deprived). Methods: The research was carried out using computer-based tests of the Vienna Test System (COG, DT, WAFF) and pupillography (F 2 D Fit-For-Duty). Results: There were no statistically significant effects of the main genders and groups on sleepiness measured by the pupillography. There was no deterioration in the results after deprivation among women and men in the COG test. Changes were noted in the DT and WAFF tests, and their size depended on the test. The number of false responses in psychomotor test was higher in women after sleep deprivation. Conclusion: One night of sleep deprivation may not have been a negative enough stimulus for young, healthy women and men to reveal gender differences in psychomotor tests. Low sleep levels can lead to low productivity at work and accidents due to reduced vigilance. Insufficient sleep in the long term can lead to poor health, resulting in hypertension, obesity and depression.

Normative data for the Montreal Cognitive Assessment in an Italian population sample

The Montreal Cognitive Assessment (MoCA) is a rapid screening battery, also including subtests to assess frontal functions such as set-shifting, abstraction and cognitive flexibility. MoCA seems to be useful to identify non-amnestic mild cognitive impairment (MCI) and subcortical dementia; it has high sensitivity and specificity in distinguishing MCI from mild Alzheimer's Disease. Previous studies revealed that certain items of MoCA may be culturally biased and highlighted the need for population-based norms for the MoCA. The aim of present study was to collect normative values in a sample of Italian healthy subjects. Four hundred and fifteen Italian healthy subjects (252 women and 163 men) of different ages (age range 21-95 years) and educational level (from primary to university) underwent MoCA and Mini Mental State Examination (MMSE). Multiple linear regression analysis revealed that age and education significantly influenced performance on MoCA. No significant effect of gender was found. From the derived linear equation, a correction grid for MoCA raw scores was built. Inferential cut-off score, estimated using a non-parametric technique, is 15.5 and equivalent scores were computed. Correlation analysis showed a significant but weak correlation between MoCA adjusted scores with MMSE adjusted scores (r = 0.43, p < 0.001). The present study provided normative data for the MoCA in an Italian population useful for both clinical and research purposes.
