The Role of Cognitive Reserve in Protecting Cerebellar Volumes of Older Adults with mild Cognitive Impairment.

The present study aims to investigate the relationship between cerebellar volumes and cognitive reserve in individuals with Mild Cognitive Impairment (MCI). A description of proxies of cerebellar cognitive reserve in terms of different volumes across lobules is also provided. 36 individuals with MCI underwent neuropsychological (MoCA, MMSE, Clock test, CRIq) assessment and neuroimaging acquisition with magnetic resonance imaging at 3 T. Simple linear correlations were applied between cerebellar volumes and cognitive measures. Multiple linear regression models were then used to estimate standardized regression coefficients and 95% confidence intervals. Simple linear correlations between cerebellar lobules volumes and cognitive features highlighted a significant association between CRIq_Working activity and specific motor cerebellar volumes: Left_V (ρ = 0.40, p = 0.02), Right_V (r = 0.42, p = 0.002), Vermis_VIIIb (ρ = 0.47, p = 0.003), Left_X (ρ = -0.46, p = 0.002) and Vermis_X (r = 0.35, p = 0.03). Furthermore, CRIq_Working activity scores correlated with certain cerebellar lobules implicated in cognition: Left_Crus_II, Vermis VIIb, Left_IX. MMSE was associated only with the Right_VIIB volume (r = 0.35, p = 0.02), while Clock Drawing Test scores correlated with both Left_Crus_I and Right_Crus_I (r = -0.42 and r = 0.42, p = 0.02, respectively). This study suggests that a higher cognitive reserve is associated with specific cerebellar lobule volumes and that Working activity may play a predominant role in this association. These findings contribute to the understanding of the relationship between cerebellar volumes and cognitive reserve, highlighting the potential modulatory role of Working activity on cerebellum response to cognitive decline.

The University of Padua salivary-based SARS-CoV-2 surveillance program minimized viral transmission during the second and third pandemic wave.

BACKGROUND: The active surveillance of students is proposed as an effective strategy to contain SARS-CoV-2 spread and prevent schools' closure. Saliva for molecular testing is as sensitive as naso-pharyngeal swab (NPS), self-collected and well accepted by participants. This prospective study aimed to verify whether the active surveillance of the Padua University employees by molecular testing of self-collected saliva is an effective and affordable strategy for limiting SARS-CoV-2 spread. METHODS: A surveillance program based on self-collection of saliva every 2 weeks (October 2020-June 2021) was conducted. Among 8183 employees of the Padua University, a total of 6284 subjects voluntarily took part in the program. Eight collection points guaranteed the daily distribution and collection of barcoded salivary collection devices, which were delivered to the laboratory by a transport service for molecular testing. Quarantine of positive cases and contact tracing were promptly activated. RESULTS: Among 6284 subjects, 206 individuals were SARS-CoV-2 positive (99 by salivary testing; 107 by NPS performed for contact tracing or symptoms). The cumulative SARS-CoV-2 incidence in this cohort was 3.1%, significantly lower than that of employees not in surveillance (8.0%), in Padua (7.1%) and in the Veneto region (7.2%). Employees with positive saliva results were asymptomatic or had mild symptoms. The levels of serum antibodies after 3 months from the infection were correlated with age and Ct values, being higher in older subjects with greater viral loads. CONCLUSIONS: Salivary-based surveillance with contact tracing effectively allowed to limit SARS-CoV-2 contagion, also in a population with a high incidence.

Acetylcholinesterase inhibitors and cognitive stimulation, combined and alone, in treating individuals with mild Alzheimer's disease.

BACKGROUNDS: Acetylcholinesterase inhibitors (AChEI) and cognitive stimulation (CS) are the standard pharmacological and non-pharmacological treatments for Alzheimer's disease (AD). AIMS: The aim of this study was to investigate the effects of these treatments, alone or combined, on the neuropsychological profiles of patients with AD. METHODS: Forty participants were assigned to three groups receiving either only AChEI (n = 14), AChEI + CS (n = 15), or only CS (n = 11). Cognition was evaluated at baseline and after three months. Linear mixed-effects models were used to investigate differences among the treatments in terms of changes in the patients' neuropsychological profiles. RESULTS: Results, although preliminary because of the small sample size, suggest that a general improvement was found in patients who received AChEI + CS and those who received only CS compared with those who received only AChEI. Interestingly, individuals who received only CS showed a significant improvement in immediate memory recall than those who received only AChEI. Furthermore, the group receiving AChEI + CS showed an improvement in delayed recall than the other two groups. DISCUSSION: The combination of AChEI and CS seems to have the greatest benefit for patients with mild AD. More interestingly, CS alone is more effective than AChEI alone, even in improving memory, considered to be the "lost" cognitive domain in AD.

Religious assessment in Italian older adults: psychometric properties of the Francis Scale of Attitude toward Christianity and the Behavioral Religiosity Scale.

OBJECTIVES: Studies have shown that religiosity (R) and spirituality (S) can positively impact older adults' life. Nevertheless, no validated tools for measuring these constructs in the older Italian population are currently available. This study investigates the psychometric properties of two of the most common measures of R and S in the literature: the Francis Scale of Attitude toward Christianity short form (FSACsf) and the Behavioral Religiosity Scale (BRS). METHOD: 313 older Italians completed the questionnaires anonymously. The functioning of the items and the response scales, the factor structure, age invariance and internal consistency of both scales were investigated. RESULTS: Each scale defines a substantively unidimensional variable. Moreover, items seem, on the whole, to be well formulated. The values of the Rasch-Andrich thresholds suggest that the response scale of the FSACsf was adequate for measuring spirituality. However, this was not the case for BRS, where the response categories needed to be collapsed to measure behavioral religiosity properly. Age invariance was confirmed for each scale. Cronbach's α, composite reliability and person separation reliability revealed both scales to be internally consistent. DISCUSSION: The results suggest that the scales have solid psychometric properties, and can therefore be considered valid, reliable tools for investigating religiosity and spirituality in older people.

Investigating the Accessibility of Voice Assistants With Impaired Users: Mixed Methods Study.

BACKGROUND: Voice assistants allow users to control appliances and functions of a smart home by simply uttering a few words. Such systems hold the potential to significantly help users with motor and cognitive disabilities who currently depend on their caregiver even for basic needs (eg, opening a door). The research on voice assistants is mainly dedicated to able-bodied users, and studies evaluating the accessibility of such systems are still sparse and fail to account for the participants' actual motor, linguistic, and cognitive abilities. OBJECTIVE: The aim of this work is to investigate whether cognitive and/or linguistic functions could predict user performance in operating an off-the-shelf voice assistant (Google Home). METHODS: A group of users with disabilities (n=16) was invited to a living laboratory and asked to interact with the system. Besides collecting data on their performance and experience with the system, their cognitive and linguistic skills were assessed using standardized inventories. The identification of predictors (cognitive and/or linguistic) capable of accounting for an efficient interaction with the voice assistant was investigated by performing multiple linear regression models. The best model was identified by adopting a selection strategy based on the Akaike information criterion (AIC). RESULTS: For users with disabilities, the effectiveness of interacting with a voice assistant is predicted by the Mini-Mental State Examination (MMSE) and the Robertson Dysarthria Profile (specifically, the ability to repeat sentences), as the best model shows (AIC=130.11). CONCLUSIONS: Users with motor, linguistic, and cognitive impairments can effectively interact with voice assistants, given specific levels of residual cognitive and linguistic skills. More specifically, our paper advances practical indicators to predict the level of accessibility of speech-based interactive systems. Finally, accessibility design guidelines are introduced based on the performance results observed in users with disabilities.

Reward motivation and neurostimulation interact to improve working memory performance in healthy older adults: A simultaneous tDCS-fNIRS study.

Several studies have evaluated the effect of anodal transcranial direct current stimulation (tDCS) over the prefrontal cortex (PFC) for the enhancement of working memory (WM) performance in healthy older adults. However, the mixed results obtained so far suggest the need for concurrent brain imaging, in order to more directly examine tDCS effects. The present study adopted a continuous multimodal approach utilizing functional near-infrared spectroscopy (fNIRS) to examine the interactive effects of tDCS combined with manipulations of reward motivation. Twenty-one older adults (mean age = 69.7 years; SD = 5.05) performed an experimental visuo-spatial WM task before, during and after the delivery of 1.5 mA anodal tDCS/sham over the left prefrontal cortex (PFC). During stimulation, participants received performance-contingent reward for every fast and correct response during the WM task. In both sessions, hemodynamic activity of the bilateral frontal, motor and parietal areas was recorded across the entire duration of the WM task. Cognitive functions and reward sensitivity were also assessed with standard measures. Results demonstrated a significant impact of tDCS on both WM performance and hemodynamic activity. Specifically, faster responses in the WM task were observed both during and after anodal tDCS, while no differences were found under sham control conditions. However, these effects emerged only when taking into account individual visuo-spatial WM capacity. Additionally, during and after the anodal tDCS, increased hemodynamic activity relative to sham was observed in the bilateral PFC, while no effects of tDCS were detected in the motor and parietal areas. These results provide the first evidence of tDCS-dependent functional changes in PFC activity in healthy older adults during the execution of a WM task. Moreover, they highlight the utility of combining reward motivation with prefrontal anodal tDCS, as a potential strategy to improve WM efficiency in low performing healthy older adults.

Diagnosing mild cognitive impairment in Parkinson's disease: which tests perform best in the Italian population?

Mild cognitive impairment (MCI) is common in patients with Parkinson's disease (PD) and should be recognized early because it represents a predictor of PD-related dementia and worse disease course. Diagnostic criteria for PD-related MCI (PD-MCI) have recently been defined by a Movement Disorders Society (MDS) task force. The present study explored which neuropsychological tests perform best for a level II (i.e., comprehensive neuropsychological assessment) diagnosis of PD-MCI according to the MDS task force criteria in Italian-speaking PD patients. To this aim, we assessed a comprehensive 23-item neuropsychological battery, derived the best-performing 10-test battery (i.e., two tests per domain for each of the five cognitive domains), and explored its accuracy for diagnosing PD-MCI in comparison to the full battery in a group of PD patients. A secondary aim was to explore the role of this battery for subtyping PD-MCI according to single-domain vs. multiple-domain involvement. The 10-test battery showed 73% sensitivity and 100% specificity for diagnosing PD-MCI, and 69% sensitivity and 100% specificity for PD-MCI subtyping. In patients older than 70 years, we derived a slightly different 10-test battery with 84% sensitivity and 100% specificity for PD-MCI diagnosis, and 86% sensitivity and 100% specificity for PD-MCI subtyping. These 10-item neuropsychological batteries might represent a good trade-off between diagnostic accuracy and time of application, and their role in PD-MCI diagnosis and subtyping should be further explored in future prospective studies.

Cognitive reserve is a resilience factor for cognitive dysfunction in hepatic encephalopathy.

Cognitive Reserve (CR) modulates symptoms of brain disease. The aim of this study was: to evaluate the effect of CR on cognition in cirrhosis and on the mismatch between cognitive and neurophysiologic assessment of hepatic encephalopathy (HE). Eighty-two outpatient patients with cirrhosis without overt HE were studied [73% males; age: 62 (54-68) (median, interq. range) yrs.; education: 8 (6-13) yrs.]. The Psychometric Hepatic Encephalopathy Score (PHES) was used as cognitive measure of HE. The spectral analysis of the electroencephalogram (EEG) was used as neurophysiologic measure of HE. The CR was assessed by the CR Index (CRI), which was measured by the CRI questionnaire (CRIq) ( http://cri.psy.unipd.it ). The PHES was altered in 28% of patients and the EEG in 41%. Altered PHES was related to the severity of cirrhosis as assessed by Child-Pugh classification (R = 0.31, p < 0.005). Patients with maintained PHES had higher CRI than those with altered PHES (CRI = 100 ± 20 vs. 88 ± 12 vs., p < 0.01), but not the ones with normal EEG compared to those with abnormal EEG (CRI = 96 ± 17 vs. 98 ± 17 vs. p: n.s.).The PHES, but not the EEG, was found to be related to the CRI (r = 0.35, p < 0.01). The mismatch between cognitive and neurophysiologic evaluation of non-overt HE (the ratio between PHES and the mean dominant frequency -MDF- of the EEG i.e., cognitive performance normalized by EEG speed) was found to be correlated to the CRI (r = 0.36, p < 0.005). CR is a resilience factor for cognitive dysfunction in cirrhosis, and is easily measurable by CRIq.

A transcranial magnetic stimulation study on response activation and selection in spatial conflict.

In choice reaction tasks, subjects typically respond faster when the relative spatial positions of stimulus and response correspond than when they do not, even when spatial information is irrelevant to the task (e.g. in the Simon task). Cognitive models attribute the Simon effect to automatic response activation elicited by spatial information, which facilitates or competes with the controlled selection of the correct response as required by task demands. In the present study, we investigated the role of the dorsal premotor cortex (PMd) in response activation and selection during spatial conflict. We applied single-pulse transcranial magnetic stimulation (TMS) to the PMd of the right and left hemispheres during the execution of a Simon task, at different times after the onset of the visual stimulus. The results showed that TMS produced a different effect on subjects' performance in two separate time windows. When TMS was applied at an early time [160-ms stimulus onset asynchrony (SOA)], we observed suppression of the Simon effect, resulting from a delay of corresponding trials. When TMS was applied at a late time (220 and 250-ms SOA), we observed an increase in the Simon effect, resulting from a delay of non-corresponding trials. These outcomes revealed that the PMd is involved both in the activation of the spatially triggered response and in response selection during spatial conflict.

Confounders in the detection of minimal hepatic encephalopathy: a neuropsychological and quantified EEG study.

BACKGROUND & AIMS: Chronic alcohol misuse, HCV infection and cirrhosis may cause cognitive alterations. The aim of the present study was to assess the influence of alcohol misuse, HCV infection and cirrhosis per se on the neuropsychological and electroencephalogram (EEG) profile and to evaluate the role of alcohol misuse and HCV infections as potential confounding factors in the detection of minimal hepatic encephalopathy. METHODS: A comprehensive neuropsychological profile and EEG spectral parameters were obtained in six age-matched groups of 30 subjects each: (i) HCV-related hepatitis without cirrhosis, (ii) chronic alcohol abusers, (iii) patients with HCV-related cirrhosis, (iv) alcohol-related cirrhosis, (v) cirrhosis not related to alcohol or HCV and (vi) healthy subjects. Cirrhotic patients were matched for MELD score. RESULTS: The factor 'cirrhosis' was associated with low Phonemic Verbal Fluency (PVF) and Difference between Trail Making Test B and A (TMT) (B-A) (P < 0.001). Chronic alcohol misuse was associated with low PVF, TMT (B-A), Memory with Interference Task at 10 (ITM 10) and 30 s (ITM 30) (all P < 0.05). An interaction was found between the factors 'cirrhosis', 'alcohol misuse' and tests (P < 0.01). HCV hepatitis reduced ITM 10 (P < 0.05), but no interaction was found between 'cirrhosis', 'HCV infection' and tests (P = 0.14). The EEG parameters were mainly influenced by 'cirrhosis' (P < 0.05), and EEG alterations were more pronounced in patients with alcoholic cirrhosis (P = 0.04). CONCLUSIONS: Cirrhosis per se, chronic alcohol misuse and HCV infection were found to be associated with cognitive dysfunction. In patients with cirrhosis, the interaction with alcohol misuse further impinged on brain dysfunction.

The Italian version of the Brain Injury Rehabilitation Trust (BIRT) personality questionnaires: five new measures of personality change after acquired brain injury.

The aim of this study was to describe the translation and adaptation of the BIRT personality questionnaires for the Italian population. This included the replication of validity testing and the collection of normative data. Following translation and adaptation according to cross-cultural guidelines, the questionnaires were administered as a pre-test to a sample of 20 healthy subjects and then to 10 patients. The questionnaires were then administered to 120 healthy subjects equally distributed by sex, education, and age, to collect normative data from an Italian population. The questionnaires were easily administered to both healthy subjects and patients. Statistical analysis on normative data was conducted to find the mean value for each questionnaire. This study lays the foundations for using a new instrument to assess behavioral changes after acquired brain injury on the Italian population.

Psychometric and EEG changes after carotid endarterectomy.

The influence of carotid stenosis and its surgical treatment on brain function is still poorly defined. We therefore performed a study to assess psychometric and quantified EEG findings after carotid endarterectomy (CEA). Sixty-nine non-demented patients (aged 72 ± 7 years) with severe carotid stenosis (≥ 70%) eligible for CEA were studied. Forty patients (group A) had unilateral stenosis, and 29 patients (group B) had bilateral stenosis. Before and 5 months after CEA all the patients were evaluated by the Trail Making Test A, the Symbol Digit Test, and spectral EEG analysis. At baseline, compared to group A, group B patients performed slowly the Trail Making Test A (Z: 1.45 ± 1.4 vs. 0.76 ± 1.3; p < 0.05), but not the Symbol Digit Test (Z: 0.83 ± 1.38 vs. 0.64 ± 1.26; p = 0.59). Altogether, the patients with at least one abnormal psychometric test were 29% (group A: 26%; group B: 33%, p = 0.56). The EEG did not differ significantly between patients of group A compared to group B. After CEA, psychometric tests improved (mean Z score from 0.73 ± 1.12 to 0.45 ± 1.15, p < 0.05). The improvement was similar in group A and B. The EEG mean dominant frequency improved only in group B patients and it was related to the improvement in psychometric tests (r = 0.43, p = 0.05). Low psychometric performance was detectable in about 1/ 3 of non-demented patients with severe carotid stenosis. CEA improved mental performance and, in patients with severe bilateral stenosis, accelerated the EEG frequency.

Motivation-cognition interaction: how feedback processing changes in healthy ageing and in Parkinson's disease.

BACKGROUND: Several studies have investigated the interaction between motivation and cognition in both young and older adults, but with inconsistent results. A recent hypothesis suggests exploring the role of dopamine to study this interaction. AIMS: To explore how different motivational states can modulate cognitive control, as well as investigate the hypothesis of a dopaminergic role in this phenomenon. METHODS: 27 young subjects, 15 healthy old subjects, and 15 Parkinson's disease (PD) patients took part in this study. The motivational Simon task-a new paradigm in which rewards and punishments are delivered to promote fast and accurate responses-was employed. The participants' performance was evaluated by analysing their reaction times and accuracy, while employing a diffusion model analysis. RESULTS: The employment of positive and negative feedback significantly modulated performance in a conflict task. In both, the young and older participants, the speed-accuracy trade-off significantly changed in response to different motivational incentives (p < .005), although in opposite ways. On the contrary, PD patients showed an absence of performance modulation in response to positive and negative feedback. DISCUSSION AND CONCLUSIONS: In normal conditions, motivation interacts with cognitive control to modulate decisional aspects of a response in a conflict task. The elderly modulate their performance in response to positive and negative feedback differently from young adults, showing a classical positivity effect. The impairment manifested by PD patients, which is compatible with the literature about feedback processing deficits in this clinical condition, can support the hypothesis that the interaction between motivation and cognitive control is mediated by dopaminergic functionality.

Cognitive impairment and electroencephalographic alterations before and after liver transplantation: what is reversible?

The influence of liver transplantation (LT) on mental performance is debated, as is the role of pretransplant overt hepatic encephalopathy (OHE). The aim of this study was to evaluate the time course of the neuropsychological and electroencephalogram (EEG) features of patients with cirrhosis before and after LT with respect to prior OHE. The study population included 65 patients with cirrhosis on the transplant waiting list; 23 had a history of OHE. Each patient underwent an extensive psychometric assessment (10 tests, including paper and pencil tests and a computerized test) and an EEG before and 9 to 12 months after LT. For a subgroup of 11 patients, the assessment was also performed 3 and 6 months after LT. EEGs were analyzed spectrally, and the mean dominant frequencies were obtained. Both psychometric tests and EEGs improved 9 to 12 months after LT. Patients with a history of OHE before LT had worse cognitive performances (P < 0.001) and EEG performances in comparison with their counterparts with a negative history. They also showed greater cognitive improvement after LT (P < 0.01); however, their global cognitive performance remained slightly impaired (P < 0.01). After LT, EEGs normalized for 98% of the patients (P < 0.01), regardless of any history of OHE. In the subgroup of patients evaluated every 3 months, psychometric and EEG findings showed deterioration at 3 months and subsequently steady improvements from 6 months onward. In conclusion, both neuropsychological and EEG performances had significantly improved 1 year after LT. Patients with a history of OHE showed greater improvements after LT than patients with a negative history, but their global cognitive function remained slightly worse; in contrast, EEGs normalized in both groups.

Cognitive reserve in a cross-cultural population: the case of Italian emigrants in Montreal.

BACKGROUND: Cognitive reserve could be defined as the accumulation of experiences, abilities, knowledge and changes that occur throughout the lifespan. One of the most difficult changes in life is the experience of emigrating to a foreign country. AIMS: The present investigation aimed to compare the cognitive reserve of two paired groups of elderly: Italians living in Italy and Italians who in adult age (around 20 years) emigrated to Montreal. Both groups attended the same years of school, in Italy. METHODS: Cognitive reserve was measured in the two groups by a structured and standardised questionnaire, the cognitive reserve questionnaire. RESULTS: Cognitive reserve showed to be significantly higher in the Italian-Canadian individuals (i.e. Italians who emigrated). CONCLUSIONS: Emigration might act as an environmental factor that enriches people's lifestyle and reflects itself in the amount of their cognitive reserve.

Mood moderates the effects of prefrontal tDCS on executive functions: A meta-analysis testing the affective state-dependency hypothesis.

BACKGROUND: In recent decades, numerous studies have investigated the effects of transcranial direct current stimulation (tDCS) on cognitive functioning. However, results of these studies frequently display inconsistency and pose challenges regarding replicability. The present work aimed at testing the hypothesis of mood as potential moderator of prefrontal tDCS effects on executive functions (EF). This hypothesis refers to the relationship between mood and EF, as well as to the association of mood with the dorsolateral prefrontal cortex (dlPFC) activity. METHODS: We conducted a meta-analysis of 11 articles where the dlPFC was stimulated with anodal tDCS, EF were measured, and mood was assessed prior to the stimulation. We then conducted a meta-regression to examine whether mood moderated the tDCS effects on EF. RESULTS: While no significant effect of tDCS on EF emerged from the meta-analysis, the meta-regression indicated that mood plays a significant role as moderator, with greater tDCS effects on EF in individuals with higher depressive symptoms. LIMITATIONS: The limited number of studies included, the heterogeneous samples considered, and the limited generalizability to other non-invasive brain stimulation techniques and affective states. CONCLUSIONS: Findings suggest that evaluating mood prior to stimulation could increase the sensitivity and specificity of tDCS application, and provide the first meta-analytic evidence in favor of the affective state-dependency hypothesis.

A meta-analysis of non-invasive brain stimulation (NIBS) effects on cerebellar-associated cognitive processes.

Non-invasive brain stimulation (NIBS) techniques, including transcranial magnetic stimulation (TMS) and transcranial electrical stimulation (tES), have provided valuable insights into the role of the cerebellum in cognitive processes. However, replicating findings from studies involving cerebellar stimulation poses challenges. This meta-analysis investigates the impact of NIBS on cognitive processes associated with the cerebellum. We conducted a systematic search and analyzed 66 studies and 91 experiments involving healthy adults who underwent either TMS or transcranial direct current stimulation (tDCS) targeting the cerebellum. The results indicate that anodal tDCS applied to the medial cerebellum enhances cognitive performance. In contrast, high-frequency TMS disrupts cognitive performance when targeting the lateral cerebellar hemispheres or when employed in online protocols. Similarly, low-frequency TMS and continuous theta burst stimulation (cTBS) diminish performance in offline protocols. Moreover, high-frequency TMS impairs accuracy. By identifying consistent effects and moderators of modulation, this meta-analysis contributes to improving the replicability of studies using NIBS on the cerebellum and provides guidance for future research aimed at developing effective NIBS interventions targeting the cerebellum.

Eye-to-Hand Coordination in Obstructive Sleep APNEA Syndrome: a Descriptive Study.

OBJECTIVE: Psychomotor slowdown was observed in individuals with Obstructive Sleep Apnea Syndrome (OSAS). Previous studies evaluated separately cognitive and motor reaction times, finding that OSAS individuals show a specific impairment in the latter. The present study investigates whether eye-to-hand coordination (EHC), a specific psychomotor ability, is compromised in OSAS. METHOD: The EHC was measured in 30 OSAS individuals who were matched with 30 healthy controls by the Two-Hand Coordination Test analyzing the speed, accuracy, and coordination; the role of these variables was investigated in predicting the group they belonged to. RESULTS: The OSAS participants showed poorer performance in the execution accuracy (t(55) = -3.36, d'Cohen = -0.89, p ≤ .001), which was also found to be the only predictor of the belonging to group (ß = 0.43 (0.18), p < .05). CONCLUSIONS: The OSAS individuals show impairments in EHC and in correcting their error (executive slowdown). This is the first investigation exploring EHC coordination in this population and contributes in understanding the psychomotor slowness characterizing OSAS.

Trauma Shaping the Psychopathological Correlates of Patients with Long-COVID: A 6-Months Longitudinal Study with Repeated Measures Mixed Models.

This research aimed at investigating how the experience of trauma can influence the psychological correlates of long-COVID over time in a clinical sample of patients hospitalized because of COVID-19. Through a longitudinal research design, 70 post-acute patients with COVID-19 were followed-up after hospital discharge in 3-time points up to 6 months and completed the Post-traumatic Stress Disorder Checklist for DSM-5 (PCL-5) and the Symptoms Checklist-90-Revised (SCL-90 R). Repeated measures mixed models with random intercept were used to evaluate the effect of trauma (yes/no) over time (T1, T2, T3) on the SCL-90-R scales. Results showed that patients with trauma display significantly worse psychological outcomes in all the SCL-90-R dimensions [all padj < .05 for the principal effects of trauma(y)], especially in symptoms of depression [time 2 vs time 1*trauma(y): b = -3.86, 95%CI (-7.18, -0.53), padj = .035; time 3 vs time 1*trauma(y): b = -4.77, 95%CI (-8.10, -1.45), padj = .011], anxiety [time 3 vs time 1*trauma(y): b = -4.54, 95%CI (-7.72, -1.37), padj = .011], and obsessive-compulsive difficulties [time 3 vs time 1*trauma(y): b = -4.03, 95%CI (-7.20, -0.86), padj = .027]. These findings shed light on the long-term psychological consequences of COVID-19 among hospitalized patients and highlight the key role of trauma, suggesting its assessment to tailor psychological interventions.
