The Difference

Abstract Introduction Sleep disturbance in children with attention-deficit/hyperactivity disorder (ADHD) is frequent, and lead to shorter sleep duration which has been associated with lower performance on sustained attention tasks. However, no study has investigated this association in adolescents with ADHD. We sought to explore whether the association between sleep and sustained attention performance of children with ADHD is similar in adolescents with ADHD given that sleep patterns are different. Methods Parents of 32 children (mean age = 8.0; SD = 1.3) and 10 adolescents (mean = 15.2; SD = 1.3) with ADHD completed a developmental questionnaire including sleep questions. Children and adolescents were medication free and underwent a comprehensive neuropsychological evaluation. Three sleep variables were extracted from the questionnaire, namely the duration of the sleep period during week nights and weekends as well as the difference between the two (“weekend shift”). The Continuous Performance Test was used to measure sustained attention (omission, commission, hit reaction time). Pearson correlations between sleep variables and sustained attention measures were calculated. Results Children showed a positive correlation between hit reaction time and the duration of the sleep period during week nights (r = 0.37; p =0.04), weekends (r = 0.51; p = 0.004) and the weekend shift (r = 0.37; p =0.04). No significant correlations were found in the adolescent group. Conclusion The fact that no significant associations were found in the adolescent group suggest an improvement of the arousal system through brain development in ADHD, or that other mechanisms could be involved in the etiology of ADHD in adolescents.

The Difference

We studied groups of 39 schizophrenic subjects, 35 schizotypic subjects, and 33 control subjects, comparing them on a standard sustained attention task called the Continuous Performance Test (identical pairs version). The expected negative relationship between performance on sustained attention and psychopathology was confirmed by differences among the three groups which were in the direction predicted, although only the difference between the schizophrenic group and the other two groups was significant. This finding adds evidence to the view from research on high risk and attention with schizophrenic subjects that subtle attention deficits are present among subjects within the schizophrenia spectrum. Consequently, our results can be understood as supporting a dimensional theory of psychopathology.

This study investigated the performance of children with attention deficit hyperactivity disorder (ADHD) and dyslexia using Conners' Continuous Performance Test (CCPT). The clinical groups were composed of 52 children with ADHD and 32 children with dyslexia. Performance in the CCPT was evaluated using ANCOVA to compare the clinical groups with the normative Brazilian sample. The ADHD group performed worse than the normative sample in almost all of the measurements, except for reaction time and response style. The dyslexia group scored higher on commissions, variability, perseverations and inconsistency in the reaction time over the six time blocks (Hit SE Block Change) than the children in the normative Brazilian sample. The ADHD and dyslexia groups differed in omission measurements, Hit RT SE, variability, perseverations, Hit RT Interstimulus Intervals (ISI) Change and Hit SE ISI Change. We thus found that the dyslexia group had specific deficit patterns, with greater response to non-target stimuli, greater perseveration and response variability, and difficulties in hit reaction time as the test progressed.

The Impact

IntroductionSome studies have related processing speed with functionality. A more discriminative analysis of different components of this neuropsychological construct is needed.Objectives/AimsTo measure the performance of a group of patients with schizophrenia in reaction time, processing velocity and sustained attention. To compare the impact on functioning of these three measures.MethodsNinety-eight outpatients between 18 and 65 years diagnosed with schizophrenia, based on the DSM-V, with a 3-month period of clinical stability, were recruited. Sociodemografic and clinical data were collected: PANSS scale, Akathisia Simpson-Angus Brief Scale, State-Trait Anxiety Inventory (STAI) and Global Functioning Scale (GAF). The following variables were measured: reaction time (SUPERLAB PRO), processing speed (TMT-A, subtest of symbol coding BACS, verbal fluency) and sustained attention (Continuous Performance Test).ResultsFunctionality of patients was correlated to Elective Reaction Time (the subject must react to different types of stimuli and to choose between several possible answers) [P = −0.205; P = 0.047], but NOT with Simple Reaction Time [P = 0.109; P = 0.293)]. Functionality was significantly correlated to Symbols Coding (P = 0.328; P = 0.001), and a trend was observed regarding semantic fluency (P = 0.190; P = 0.06) and the TMT-A (P = −0.179; P = 0.08). In CPT, Correct Detection was correlated with GAF score (P = 0.380; P = 0.000) but not omission errors. The model of lineal regression shows a differential impact of every measure in global functioning.ConclusionsReaction time, processing speed and sustained attention are different variables and each of them have impact on functioning in schizophrenia.Disclosure of interestThe authors have not supplied their declaration of competing interest.

There are known relationships between psychopathology, personality, and executive function (EF), though the association between personality and EF, independent of psychopathology, remains understudied. The present study investigated relationships between Five Factor Model personality traits and indices of response inhibition, sustained attention, and response variability on a continuous performance test (CPT) among 50 healthy adults (male = 27, female = 23; Mage = 19.9 years, range 18–24 years) of primarily Caucasian descent (58.0%). Participants performed an open-source CPT, the Psychology Experiment Building Language Battery Test of Attentional Vigilance (TOAV), and completed self-ratings of conscientiousness, extraversion, and neuroticism on an inventory developed from the public-domain International Personality Item Pool. After controlling for the influences of age, gender, and other personality traits, neuroticism was significantly associated with faster error reaction time and a higher frequency of multiple responses. Neuroticism was also nominally predictive of more frequent commission errors and faster correct and mean reaction time. The present findings indicate that neuroticism is associated with error-prone behavioral performance on a CPT, suggesting that a propensity to experience negative emotions may manifest as impulsivity and hyperactivity on performance-based measures of EF.

Abstract. Several studies have shown that Continuous Performance Tests (CPT) can diagnose Attention Deficit Hyperactivity Disorder (ADHD) better than other tests. Research reporting comparisons of two or more CPT-type tests is scarce. The purpose of the study was to compare the Mathematics Continuous Performance Test (MATH-CPT) with another CPT-type test (CPT II) and a questionnaire (the Brown Scale). The comparison was carried out by looking at correlations among subscales and checking the precision of detecting ADHD. Ninety-five high school and college students participated in the study, 41 with ADHD were the research group and 54 were the control group. The participants performed the two tests and answered the questionnaire. The results showed that the MATH-CPT correctly identified 74.50% of the participants of both groups as compared to the 71.60% of the CPT II. Correlations between the two CPT-type tests were moderate; however, they were similar to correlations found in other studies comparing similar tools. The MATH-CPT, final attention formula, showed significant correlations with the Brown scales, while the CPT II, confidence index associated with ADHD assessment, showed nonsignificant correlations with the questionnaire. The study indicated that MATH-CPT can be used with a clinical population of ADHD and for research purposes.

DNA methylation levels are associated with neurodevelopment. Attention-deficit/hyperactivity disorder (ADHD), characterized by attention deficits, is a common neurodevelopmental disorder. We used methylation microarray and pyrosequencing to detect peripheral blood DNA methylation markers of ADHD. DNA methylation profiling data from the microarray assays identified potential differentially methylated CpG sites between 12 ADHD patients and 9 controls. Five candidate CpG sites (cg00446123, cg20513976, cg07922513, cg17096979, and cg02506324) in four genes (LIME1, KCNAB2, CAPN9, and SPTBN2) were further examined with pyrosequencing. The attention of patients were tested using the Conners’ Continuous Performance Test (CPT). In total, 126 ADHD patients with a mean age of 9.2 years (78.6% males) and 72 healthy control subjects with a mean age of 9.3 years (62.5% males) were recruited. When all participants were categorized by their CPT performance, the DNA methylation levels in LIME1 (cg00446123 and cg20513976) were found to be significantly higher and those in SPTBN2 (cg02506324) were significantly lower in children with worse CPT performance. Therefore, DNA methylation of two CpG sites in LIME1 and one CpG site in SPTBN2 is associated with attention deficits in children. DNA methylation biomarkers may assist in identifying attention deficits of children in clinical settings.

AbstractAttention is a complex cognitive function that is necessary for learning, for following social norms of behaviour and for effective performance of responsibilities and duties. It is especially important in sensitive occupations requiring sustained attention. Improvement of dietary diversity (DD) is recognised as an important factor in health promotion, but its association with sustained attention is unknown. The aim of this study was to determine the association between auditory and visual sustained attention and DD. A cross-sectional study was carried out on 400 women aged 20–50 years who attended sports clubs at Tehran Municipality. Sustained attention was evaluated on the basis of the Integrated Visual and Auditory Continuous Performance Test using Integrated Visual and Auditory software. A single 24-h dietary recall questionnaire was used for DD assessment. Dietary diversity scores (DDS) were determined using the FAO guidelines. The mean visual and auditory sustained attention scores were 40·2 (sd35·2) and 42·5 (sd38), respectively. The mean DDS was 4·7 (sd1·5). After adjusting for age, education years, physical activity, energy intake and BMI, mean visual and auditory sustained attention showed a significant increase as the quartiles of DDS increased (P=0·001). In addition, the mean subscales of attention, including auditory consistency and vigilance, visual persistence, visual and auditory focus, speed, comprehension and full attention, increased significantly with increasing DDS (P<0·05). In conclusion, higher DDS is associated with better visual and auditory sustained attention.
