RESUMO

OBJECTIVE: The aim of this study was to assess the prevalence of brain injury (BI) and its relationship to cognitive and psychological outcomes in women survivors of intimate partner violence (IPV) in Colombia, South America. SETTING: Women's shelters and organizations in Barranquilla, Colombia. PARTICIPANTS: Seventy women from the city of Barranquilla, Colombia, who experienced any form of IPV. DESIGN: Cross-sectional, retrospective. MAIN MEASURES: Participants were administered the computerized EMBRACED neuropsychological battery to assess learning, working and long-term memory, cognitive flexibility, and processing speed. Participants also completed measures of psychological symptoms. Partner violence severity was assessed with a semistructured interview for survivors of domestic violence. Presence and severity of IPV-related BI were assessed using the Brain Injury Severity Assessment (BISA). RESULTS: Thirty-one percent of women sustained at least one BI during an abusive relationship, and 10% sustained repetitive BIs. Furthermore, BI was negatively associated with measures of long-term and working memory, cognitive flexibility, as well as a trending ( P = .05) positive association with depression. With the exception of the relationship between BI and cognitive flexibility, which was substantially reduced and no longer significant, all of these relationships were nearly identical in strength when controlling for abuse severity, socioeconomic status, and educational level. CONCLUSION: These data are the first to specifically examine IPV-related BI in relation to cognitive and psychological functioning in a sample of Colombian women. These data add cross-cultural knowledge to the limited work in this area that has largely focused on women in North America.

RESUMO

National-level monitoring of quality of early childhood education (ECE) is key to achieving inclusive and equitable education. Most countries report structural quality while process characteristics are rarely observed at the national level. This study examined the associations between ECE and children's development in a middle-income country using data from a nationally representative sample of public centers serving Colombian children (N = 3163; M = 4.3 years, 50% girls; 42% Mestizo, 16% White, 15% Afro-Colombian, 4% Indigenous, 23% not reported). Descriptive findings evidenced low to moderate quality. Multilevel models showed several positive associations between structural and process quality and child outcomes. Results have implications for the existing literature and highlight the feasibility of quality monitoring in low- and middle-income countries.

RESUMO

Children with attention-deficit/hyperactivity disorder (ADHD) present a deficit in inhibitory control. Still, it remains unclear whether it comes from a deficit in reactive inhibition (ability to stop the action in progress), proactive inhibition (ability to exert preparatory control), or both.We compared the performance of 39 children with ADHD and 42 typically developing children performing a Simon choice reaction time task. The Simon task is a conflict task that is well-adapted to dissociate proactive and reactive inhibition. Beyond classical global measures (mean reaction time, accuracy rate, and interference effect), we used more sophisticated dynamic analyses of the interference effect and accuracy rate to investigate reactive inhibition. We studied proactive inhibition through the congruency sequence effect (CSE).Our results showed that children with ADHD had impaired reactive but not proactive inhibition. Moreover, the deficit found in reactive inhibition seems to be due to both a stronger impulse capture and more difficulties in inhibiting impulsive responses. These findings contribute to a better understanding of how ADHD affects inhibitory control in children.

RESUMO

There is an urgent need to strengthen early childhood development and education in emergencies (ECDEiE) globally. Colombia has faced protracted and acute crises for decades. Also, the country has applied a unique approach to holistic and integrated ECDE policy formulation. We argue that these characteristics offer a valuable country-case to identify barriers and levers to the operationalization of ECDEiE. We applied a sector-wide analysis protocol that harmonized components of the Humanitarian Programme Cycle by the Inter-Agency Standing Committee and of a framework to characterize the governance of ECDE systems. The study outlines how the policy and program characteristics identified may represent levers or barriers to the effective operationalization of ECDEiE in Colombia. We discuss how these attributes could be considered in the trans-sectoral dialogue between ECDE and humanitarian actors with the aim of strengthening ECDEiE systems globally.

RESUMO

BACKGROUND: Ethanol (EtOH), one of the most widely consumed substances of abuse, can induce brain damage and neurodegeneration. EtOH is centrally metabolized into acetaldehyde, which has been shown to be responsible for some of the neurophysiological and cellular effects of EtOH. Although some of the consequences of chronic EtOH administration on cell oxidative status have been described, the mechanisms by which acute EtOH administration affects the brain's cellular oxidative status and the role of acetaldehyde remain to be elucidated in detail. METHODS: Swiss CD-I mice were pretreated with the acetaldehyde-sequestering agent d-penicillamine (DP; 75 mg/kg, i.p.) or the antioxidant lipoic acid (LA; 50 mg/kg, i.p.) 30 minutes before EtOH (2.5 g/kg, i.p.) administration. Animals were sacrificed 30 minutes after EtOH injection. Glutathione peroxidase (GPx) mRNA levels; GPx and glutathione reductase (GR) enzymatic activities; reduced glutathione (GSH), glutathione disulfide (GSSG), glutamate, g-L-glutamyl-L-cysteine (Glut-Cys), and malondialdehyde (MDA) concentrations; and protein carbonyl group (CG) content were determined in whole-brain samples. RESULTS: Acute EtOH administration enhanced GPx activity and the GSH/GSSG ratio, while it decreased GR activity and GSSG concentration. Pretreatment with DP or LA only prevented GPx activity changes induced by EtOH. CONCLUSIONS: Altogether, these results show the capacity of a single dose of EtOH to unbalance cellular oxidative homeostasis.

RESUMO

BACKGROUND: It is well known that cryopreserving seeds with high water content is detrimental to survival, but biochemical and structural parameters of cryostored hydrated common bean seeds have not been published. OBJECTIVE: The objective of this work was to study the effect of liquid nitrogen exposure on selected biochemical and structural parameters of hydrated Phaseolus vulgaris seeds. MATERIALS AND METHODS: We cryopreserved seeds at various moisture contents and evaluated: germination; electrolyte leakage; fresh seed weight; levels of chlorophyll pigments, malondialdehyde, other aldehydes, phenolics and proteins; thickness of cotyledon epidermis, parenchyma, and starch storage parenchyma; and radicle and plumule lengths. RESULTS: Germination was totally inhibited when seeds were immersed in water for 50 min (moisture content of 38%, FW basis) before cryopreservation. The combined effects of seed water imbibition and cryostorage decreased phenolics (free, cell wall-linked, total), chlorophyll a and protein content. By contrast, electrolyte leakage and levels of chlorophyll b and other aldehydes increased as a result of the combination of these two experimental factors. These were the most significant effects observed during exposure of humid seed to liquid nitrogen. CONCLUSION: Further studies are still required to clarify the molecular events taking place in plant cells during cryostorage.

RESUMO

Existing published studies about health-related quality of life (HRQOL) in caregivers of dementia patients living in Latin American countries are very limited. However, cultural aspects, personal values, and social structure may affect the way caregivers experience their role in different societies. The current study investigated the relationship between HRQOL and psychological factors using a cross-sectional design. The sample consisted of 102 informal caregivers of patients with dementia from Bogotá, Colombia, South America. Measures included the Patient Health Questionnaire (PHQ-9) for depression, the Satisfaction with Life Scale (SWLS), the Zarit Burden Interview, and the Short Health Questionnaire (SF36) for HRQOL. Canonical correlations revealed that there was a significant relationship between caregivers' mental health and HRQOL, such that caregivers with better satisfaction with life and less symptoms of depression had more vitality and better general health. There is a strong relationship between mental health and health-related quality of life in Colombian caregivers of dementia patients living in their country of origin. Specific aspects of mental health, including satisfaction with life and depression, need to be addressed in order to improve caregivers' quality of life. Given that mental health care resources may be scarce in Latin American countries, culturally appropriate interventions should focus on preventing/treating depression and promote life satisfaction, as a way to improve their quality of life.

RESUMO

Sticholysin I and Sticholysin II (StI and StII) are two potent hemolysins which form pores in natural and model membranes at nanomolar concentrations. These proteins were purified from the aqueous extract of the sea anemone Stichodactyla helianthus, Ellis 1768, by gel filtration and ionic exchange chromatography. This procedure rendered StI and StII with high purity (purification factors: 36 and 50, respectively) but a low yield of hemolytic activity, HA (<3%). Additionally, these toxins exhibited very low phospholipase activity (10(-3)U/mg of protein). In this work, a mixture StI-StII was obtained (yield >95%, with an increase in specific activity: 14 times) from the animal extract using an oxidized phospholipid-based affinity chromatographic matrix binding phospholipases. Cytolysin identification in the mixture was performed by immunoblotting and N-terminal sequence analyses. Phospholipase A2 (PLA2) activity of StI-StII was relatively high (1.85U/mg) and dependent of Ca(2+). The activity resulted optimum when was measured with the mostly unsaturated soybean phosphatidylcholine (PC), when compared to the less unsaturated egg PC or completely saturated dipalmitoyl PC, in the presence of 40mM Ca(2+) at pH 8.0. This Ca(2+) concentration did not exert any effect on binding of StI-StII with soybean PC monolayers. Then, PLA2 activity seems not be required to binding to membranes.

RESUMO

BACKGROUND: The cAMP-dependent protein kinase (PKA) signaling transduction pathway has been shown to play an important role in the modulation of several ethanol (EtOH)-induced behavioral actions. In vivo, short-term exposure to EtOH up-regulates the cAMP-signaling cascade. Interestingly, different Ca(2+) -dependent cAMP-PKA cascade mediators play a critical role in the neurobehavioral response to EtOH, being of special relevance to the Ca(2+) -dependent adenylyl cyclases 1 and 8. We hypothesize an intracellular PKA activation elicited by EtOH administration, which may be regulated by a Ca(2+) -dependent mechanism as an early cellular response. Thus, the present work aims to explore the role of Ca(2+) (internal and external) on the EtOH-activated PKA cascade. METHODS: Swiss male mice received an intraperitoneal injection of EtOH (0 or 4 g/kg), and brains were dissected following a temporal pattern (7, 15, 30, 45, 90, or 120 minutes). Either the enzymatic PKA activity or its fingerprint was analyzed on different brain areas (cortex, hypothalamus, hippocampus, and striatum). To explore the role of Ca(2+) on the EtOH-activated PKA cascade, mice were pretreated with diltiazem (0 or 20 mg/kg), dantrolene (0 or 5 mg/kg), or 3,7-Dimethyl-1-(2-propynyl)xanthine (0 or 1 mg/kg) 30 minutes before EtOH (4 g/kg) administration. After 45 minutes of EtOH administration, brains were removed and dissected to measure the PKA activity or its fingerprint. RESULTS: Results from these experiments showed an EtOH-dependent activation of PKA in different brain areas. Manipulations involving a disruption of intracellular Ca(2+) release from the endoplasmic reticulum resulted in a decreased EtOH-induced activation of PKA. On the contrary, extracellular-to-cytoplasm Ca(2+) manipulations did not prevent the PKA activation by EtOH. CONCLUSIONS: Altogether, these results show the critical role of stored Ca(2+) as an intracellular mediator of different neurobiological actions of EtOH and provide further evidence of a possible new target for EtOH within the central nervous system.

RESUMO

BACKGROUND: Hydrogen peroxide (H2 O2 ) is the cosubstrate used by the enzyme catalase to form Compound I (the catalase-H2 O2 system), which is the major pathway for the conversion of ethanol (EtOH) into acetaldehyde in the brain. This centrally formed acetaldehyde has been shown to be involved in some of the psychopharmacological effects induced by EtOH in rodents, including voluntary alcohol intake. It has been observed that different levels of this enzyme in the central nervous system (CNS) result in variations in the amount of EtOH consumed. This has been interpreted to mean that the brain catalase-H2 O2 system, by determining EtOH metabolism, mediates alcohol self-administration. To date, however, the role of H2 O2 in voluntary EtOH drinking has not been investigated. METHODS: In the present study, we explored the consequence of a reduction in cerebral H2 O2 levels in volitional EtOH ingestion. With this end in mind, we injected mice of the C57BL/6J strain intraperitoneally with the H2 O2 scavengers alpha-lipoic acid (LA; 0 to 50 mg/kg) or ebselen (Ebs; 0 to 25 mg/kg) 15 or 60 minutes, respectively, prior to offering them an EtOH (10%) solution following a drinking-in-the-dark procedure. The same procedure was followed to assess the selectivity of these compounds in altering EtOH intake by presenting mice with a (0.1%) solution of saccharin. In addition, we indirectly tested the ability of LA and Ebs to reduce brain H2 O2 availability. RESULTS: The results showed that both LA and Ebs dose-dependently reduced voluntary EtOH intake, without altering saccharin consumption. Moreover, we demonstrated that these treatments decreased the central H2 O2 levels available to catalase. CONCLUSIONS: Therefore, we propose that the amount of H2 O2 present in the CNS, by determining brain acetaldehyde formation by the catalase-H2 O2 system, could be a factor that determines an animal's propensity to consume EtOH.

RESUMO

INTRODUCTION: Heart-lung transplantation has shown a progressive decrease in the number of procedures. There is a lack of information about this field in Spain. The main goal of this study is to analyze the experience of a national reference hospital. METHODS: We performed a retrospective study of a historical cohort of heart-lung transplanted patients in a single center, during a 30 years period (from 1990 to 2021). The associations between variables were evaluated using the χ2 test or Fisher's exact test. Survival was analyzed using the Kaplan-Meier method. Differences were evaluated using the log-rank test and multivariate analysis with the Cox method. RESULTS: A decrease in the number of procedures performed in the last decade was observed [2000-2009: 19 procedures (44.2%); 2010-2021: 15 procedures (34.8%)]. Early postoperative mortality was 23.3%, falling to 13.3% from 2010. In-hospital mortality was 41%, falling to 33% from 2010. Main factors related to higher mortality: previous thoracic surgery, corticosteroid therapy, extracorporeal circulation (ECLS) greater than 200 min, ischemia time greater than 300 min, and tracheal dehiscence (p < 0.005). Overall survival at one, five, and ten years was 58%, 44.7%, and 36.1%, respectively. Factors associated with lower survival rates: previous thoracic surgery, male donor, extracorporeal circulation greater than 200 min, ischemia time greater than 300 min, tracheal dehiscence and weight difference (p < 0.005). CONCLUSIONS: There has been a progressive decrease in the number of heart-lung transplantations, being more evident in the last decade, but showing an improvement in both mortality and survival.

RESUMO

At least one in three women experience intimate partner violence (IPV) in their lifetime. The most commonly sustained IPV-related brain injuries include strangulation-related alterations in consciousness (S-AICs) and traumatic brain injuries (TBIs). Moreover, survivors of IPV-related S-AICs and/or TBIs often demonstrate psychological distress such as depression, anxiety, and post-traumatic stress. However, the co-occurrence of S-AICs and TBIs, and whether such TBIs may be moderate to severe, has not been systematically examined, and most data have been collected from women in North America. The purpose of this study was to examine the co-occurrence of IPV-related S-AICs and TBIs across a range of geographical locations and to determine the extent to which these S-AICs are related to psychological distress. Women who had experienced physical IPV (n = 213) were included in this secondary analysis of retrospectively collected data across four countries (Canada, the United States, Spain, and Colombia). The Brain Injury Severity Assessment (BISA) was used to assess IPV-related BI across all sites. Because various questionnaires were employed to assess levels of depression, anxiety, and post-traumatic stress disorder at each site, we created a standardized composite score by converting raw scores into Z-scores for analysis. Mann-Whitney U tests and chi-square tests were conducted to examine differences between women with and without experience of S-AICs and to discover if there was a relationship between the occurrence of S-AICs and TBIs. Analysis of variance and analysis of covariance (to control for the potential confounding effects of age, education, and non IPV-related TBI) were used to compare levels of psychological distress in women who had or had not experienced S-AICs. Approximately, 67% of women sustained at least one IPV-related BI (i.e., TBI and/or S-AIC). In a subsample of women who sustained at least one IPV-related BI, approximately 37% sustained both S-AICs and TBIs, 2% sustained only S-AICs (with no TBIs), and 61% sustained TBIs exclusively (with no S-AICs). Furthermore, women who had sustained S-AICs (with or without a TBI) were more likely to have experienced a moderate-to-severe BI than those who had not sustained an S-AIC (BISA severity subscale: U = 3939, p = 0.006). In addition, women who experienced S-AICs (with or without a TBI) reported higher levels of psychological distress compared with women who never experienced S-AICs, irrespective of whether they occurred once or multiple times. These data underscore the importance of assessing for S-AIC in women who have experienced IPV and when present, to also assess for TBIs and the presence of psychological distress. Unfortunately, there were methodological differences across sites precluding cross-site comparisons. Nonetheless, data were collected across four culturally and geographically diverse countries and, therefore, highlight IPV-related BIs as a global issue that needs to be aggressively studied with policies established and then implemented to address findings.

RESUMO

The 7-item Functionality Appreciation Scale (FAS) measures the extent of an individual's appreciation of their body for what it can do and is capable of doing. Although the FAS has been widely used in diverse linguistic contexts, it has not been previously translated into Spanish. Here, we examined the psychometric properties of a novel Spanish translation of the FAS in Colombian adults. A total of 1420 university students from Colombia (804 women, 616 men) completed the FAS, as well as additional validated measures. Exploratory and confirmatory factor analyses in separate subsamples supported a unidimensional model of FAS scores. The FAS evidenced scalar invariance across gender identity, with men having significantly higher FAS scores than women (Cohen's d = 0.18). FAS scores were also found to have adequate composite reliability, as well as adequate convergent (significant associations with body appreciation, appearance evaluation, and eating disorder psychopathology) and concurrent validity (significant associations with self-esteem, life satisfaction, and gratitude). Functionality appreciation incrementally predicted life satisfaction in women, but not in men. Overall, these results suggest that the Spanish FAS is a psychometrically valid and reliable tool for the assessment of functionality appreciation in university-aged populations from Colombia.

RESUMO

OBJECTIVE: To assess health-related quality of life (HRQoL) of individuals with traumatic brain injury (TBI) in Barranquilla, Colombia. PARTICIPANTS/METHODS: Thirty-one individuals with TBI and 61 healthy controls completed the SF-36, a self-report HRQoL measure composed of eight component areas: physical health problems, pain, role limitations due to physical problems or due to emotional problems, emotional well-being, social functioning, energy/fatigue and general health perceptions. RESULTS: The samples were statistically similar with respect to age, gender and education and statistically different with respect to depression, SES, social support and cognition. Compared to healthy controls, individuals with TBI had significantly lower means on all SF-36 sub-scales. However, after adjusting for depression, SES, social support and cognitive performance, significant differences remained on three of the SF-36 sub-scales. Specifically, individuals with TBI had lower adjusted means on Role-Physical (p-value < 0.005), Role-Emotional (p-value < 0.005) and Bodily Pain (p-value < 0.05). CONCLUSION: Even after controlling for depression, SES, social support and cognitive performance, individuals with TBI living in Barranquilla Colombia report having poorer quality of life across various domains, including Role-Physical, Role-Emotional and Bodily Pain. These findings suggest the need for rehabilitation health professionals to develop and implement culturally-appropriate interventions to improve quality of life in Colombian individuals with TBI.

RESUMO

Toll-like receptors (TLRs) play an important role in the innate immune response, and emerging evidence indicates their role in brain injury and neurodegeneration. Our recent results have demonstrated that ethanol is capable of activating glial TLR4 receptors and that the elimination of these receptors in mice protects against ethanol-induced glial activation, induction of inflammatory mediators and apoptosis. This study was designed to assess whether ethanol-induced inflammatory damage causes behavioral and cognitive consequences, and if behavioral alterations are dependent of TLR4 functions. Here we show in mice drinking alcohol for 5months, followed by a 15-day withdrawal period, that activation of the astroglial and microglial cells in frontal cortex and striatum is maintained and that these events are associated with cognitive and anxiety-related behavioral impairments in wild-type (WT) mice, as demonstrated by testing the animals with object memory recognition, conditioned taste aversion and dark and light box anxiety tasks. Mice lacking TLR4 receptors are protected against ethanol-induced inflammatory damage, and behavioral associated effects. We further assess the possibility of the epigenetic modifications participating in short- or long-term behavioral effects associated with neuroinflammatory damage. We show that chronic alcohol treatment decreases H4 histone acetylation and histone acetyltransferases activity in frontal cortex, striatum and hippocampus of WT mice. Alterations in chromatin structure were not observed in TLR4(-/-) mice. These results provide the first evidence of the role that TLR4 functions play in the behavioral consequences of alcohol-induced inflammatory damage and suggest that the epigenetic modifications mediated by TLR4 could contribute to short- or long-term alcohol-induced behavioral or cognitive dysfunctions.

RESUMO

BACKGROUND: Increasing evidence indicates that mu- and delta-opioid receptors are decisively involved in the retrieval of memories underlying conditioned effects of ethanol. The precise mechanism by which these receptors participate in such effects remains unclear. Given the important role of the proopiomelanocortin (POMc)-derived opioid peptide beta-endorphin, an endogenous mu- and delta-opioid receptor agonist, in some of the behavioral effects of ethanol, we hypothesized that beta-endorphin would also be involved in ethanol conditioning. METHODS: In this study, we treated female Swiss mice with estradiol valerate (EV), which induces a neurotoxic lesion of the beta-endorphin neurons of the hypothalamic arcuate nucleus (ArcN). These mice were compared to saline-treated controls to investigate the role of beta-endorphin in the acquisition, extinction, and reinstatement of ethanol (0 or 2 g/kg; intraperitoneally)-induced conditioned place preference (CPP). RESULTS: Immunohistochemical analyses confirmed a decreased number of POMc-containing neurons of the ArcN with EV treatment. EV did not affect the acquisition or reinstatement of ethanol-induced CPP, but facilitated its extinction. Behavioral sensitization to ethanol, seen during the conditioning days, was not present in EV-treated animals. CONCLUSIONS: The present data suggest that ArcN beta-endorphins are involved in the retrieval of conditioned memories of ethanol and are implicated in the processes that underlie extinction of ethanol-cue associations. Results also reveal a dissociated neurobiology supporting behavioral sensitization to ethanol and its conditioning properties, as a beta-endorphin deficit affected sensitization to ethanol, while leaving acquisition and reinstatement of ethanol-induced CPP unaffected.

RESUMO

BACKGROUND: Lung retransplantation (LR) is a valid choice with a significant risk of perioperative morbidity and mortality in selected patients with graft dysfunction after lung transplantation. Our goal is to analyse our experience in LR in terms of survival and lung function. METHODS: Retrospective study of patients undergoing LR (1990-2019). VARIABLES: recipients and procedure, early mortality, survival and lung function in patients with CLAD. Quantitative variables (mean±SD); qualitative (%). Student's t test or χ2 was used. Survival was estimated using Kaplan-Meier, compared with Log Rank. A p < 0.05 was established as significant. RESULTS: Of 784 transplanted patients, 25 patients (mean age 38.41-16.3 years, 12 men and 13 women) were LR; (CLAD (n = 19), pulmonary infarction (n = 2), airway complications (n = 2), graft dysfunction (n = 1), hyperacute rejection (n = 1), mean time to retransplantation: 5.41 ± 3.87 years in CLAD and 21.2 ± 21.4 days in non-CLAD. The 90-day mortality was 52% and 36.8% in the second period (p = 0.007), being higher in patients who required preoperative ECMO (80 vs. 20%, p = 0.04). The 1- and 5-year survival was 53.9% and 37.7%, respectively (p = 0.016). Survival of the CLAD group was greater (p = 0.08). Pre LR ECMO decreased survival (p = 0.032). After LR, FEV1 improved an average of 0.98 ± 0.13L (25.6 ± 18.8%) (p = 0.001). CONCLUSIONS: LR is a high mortality procedure that requires careful selection of patients with better results in patients with CLAD. The lung function of patients with CLAD improved significantly.

RESUMO

The number of computerized and reliable performance validity tests are scarce. This study aims to address this issue by validating a free and computerized performance validity test: the Coin in Hand-Extended Version (CIH-EV). The CIH-EV test was administered in four countries (Colombia, Spain, Portugal, and the United States) and performance was compared with other commonly used validated tests. Results showed that the CIH-EV has at least 95% specificity and 62% sensitivity, and performance was highly correlated with scores on the Test of Memory Malingering, Victoria Symptom Validity Test, and Digit Span of the Wechsler Adult Intelligence Scale. There were no significant differences in scores across countries, suggesting that the CIH-EV performs similarly in a variety of cultures. Our findings suggest that the CIH-EV has the potential to serve as a valid validity test either alone or as a supplement to other commonly used validity tests.

RESUMO

Intrathoracic goitre is defined as that goitre which is partially or totally found in the anterior or posterior mediastinum, and its incidence is associated with multinodular goitre. The diagnosis is relatively easy, mainly with imaging tests, and treatment varies, but of choice, surgical treatment is recommended. This article attempts to present a review of the literature on the diagnosis and management of this disease.

RESUMO

We compared the performance of children with ADHD and typically developing children on two temporal tasks, a bisection task and a reproduction task, in auditory and visual modalities. Children with ADHD presented a larger variability when performing auditory and visual temporal tasks. Moreover, they overestimated the durations in bisection tasks and underproduced duration intervals in the visual reproduction task. In the context of the pacemaker-accumulator model, these results suggest that temporal deficits might result from a dysfunction in the switch and/or memory impairment.
