OBJECTIVES: To study the intellectual level and the factors influencing the intelligence in children aged 6-16 years with attention deficit hyperactivity disorder (ADHD). METHODS: A retrospective study was conducted on 2 861 children who were diagnosed with ADHD according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition between October 2014 and September 2022 at Henan Children's Hospital. The Wechsler Intelligence Scale for Children-Fourth Edition was used to assess the intellectual levels of the ADHD children. Based on intelligence quotient (IQ) scores, the intellectual levels were classified into five categories: borderline (70-79), low average (80-89), average (90-109), high average (110-119), and superior (≥120). The intellectual levels among the children of different genders, grades, and parental education levels were compared. RESULTS: Among the 2 861 ADHD children, 569 (19.89%) were classified as borderline, 846 (29.57%) as low average, 1 304 (45.58%) as average, 111 (3.88%) as high average, and 31 (1.08%) as superior. The boys had lower scores in working memory, processing speed, and overall IQ than the girls (P<0.05). There were significant differences in perceptual reasoning, working memory, processing speed, and overall IQ scores among different grade groups (P<0.05). The scores in language comprehension, perceptual reasoning, working memory, processing speed, and overall IQ were found to be associated with parental education level in ADHD children (P<0.05). CONCLUSIONS The proportion of ADHD children with low average and borderline intellectual levels is relatively high. The IQ level of ADHD children is influenced by gender, grade level and parental education level.

OBJECTIVE: To study the intellectual characteristics of children with attention deficit hyperactivity disorder (ADHD) and developmental dyslexia (DD). METHODS: A total of 55 children with ADHD and DD (ADHD+DD group), 150 children with ADHD alone (ADHD group), and 22 children with DD alone (DD group) were enrolled as subjects. Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) was used to evaluate and compare intellectual characteristics among the three groups. RESULTS: There were significant differences in the scores of full-scale intelligence quotient (FSIQ), verbal comprehension index, perceptual reasoning index, and working memory index among the three groups ( CONCLUSIONS Compared with the children with ADHD alone, the children with ADHD and DD have more severe impairment of FSIQ, verbal comprehension, perceptual reasoning, and working memory, and therefore, it is suggested to enhance the training on similarities, vocabulary, matrix reasoning, picture concepts, and recitation for children with ADHD and DD in clinical practice.

OBJECTIVES: To study the difference in cognitive impairment between the children with benign childhood epilepsy with centrotemporal spikes (BECT) and attention deficit hyperactivity disorder (ADHD) and those with BECT or ADHD alone. METHODS: A prospective study was performed on 80 children with BECT and ADHD, 91 children with BECT, and 70 children with ADHD , who were diagnosed with the diseases for the first time. Seventy children of the same age who underwent physical examination were enrolled as the healthy control group. Event-related potential P300, Wechsler Intelligence Scale for Children, and integrated visual and auditory continuous performance test were used to measure and compare each index between groups. RESULTS: Compared with the healthy control group, the BECT+ADHD group, the BECT group, and the ADHD group had a significantly prolonged P300 latency, a significant reduction in the amplitude of P300, and significant reductions in the scores of verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), processing speed index (PSI), full scale intelligence quotient (FSIQ), auditory response control quotient (ARCQ), visual response control quotient, full response control quotient (FRCQ), auditory attention quotient (AAQ), visual attention quotient, and full attention quotient ( CONCLUSIONS Compared with the children with BECT or ADHD alone, the children with both BECT and ADHD have basically the same fields of cognitive impairment but a higher degree of cognitive impairment in some fields.

Bronchial asthma is a common chronic respiratory disease,and its diagnosis is mainly based on symptoms,signs,and pulmonary function test.Wheezing is a major symptom of asthma attack,which shows no obvious sign in the early stage while appears after the disease has progressed.Therefore,bronchial asthma is difficult to be detected in early stages,which often leads to worsening of the disease conditions.Pulmonary function test can effectively monitor upper and lower airway abnormalities and is currently the main means for monitoring asthma.However,its accuracy is highly dependent on patient's motivation and cooperation,which obviously limits the scope of application,especially for preschoolers and infants.Hence,there is an urgent need for a new technology with the function of long-term breath sound monitoring and automatic breathing detection to overcome the existing clinical deficiencies.Breath sound analysis emerges in the era of medical artificial intelligence,which can digitally process and convert the collected respiratory sounds by using a variety of different methods to form characteristic signal parameters and model the relationship between parameters and diseases.As we know,breath sounds are closely related to airway changes,and thus the detection and analysis of the sounds can provide reliable clinical information for the progress and control evaluation of asthma.This review mainly summaries the research progress of respiratory sound analysis in recent years,hoping to provide reference for further research.

Objective To analyze the differences in accuracy of different eye movement parameters in distinguishing the cooperation and non-cooperation during image completion test of patients with mental disorders caused by craniocerebral trauma. Methods One hundred and forty cases of patients with mental disorders caused by craniocerebral trauma who took psychiatric impairment assessments were collected. The 21 pictures from "image completion" of Wechsler intelligence test were used as stimulating pictures, then divided into cooperation group and non-cooperation group according to binomial forced-choice digit memory test and expert opinions. The eye movement parameters of research subjects during completion of images were obtained by the SMI eye-tracker. The accuracy of eye movement parameters in distinguishing the cooperation or non-cooperation of patients with mental disorders caused by craniocerebral trauma in psychiatric impairment assessments were evaluated by the ROC curve. Results During the process of the image completion test, the area under curve （AUC） value of frequency of blink, frequency of fixation, pupil size, frequency of saccade, latency of saccade, average acceleration of saccade, the average and peak longitudinal velocity of saccade was above 0.5. When it comed to a specific stimulating picture, the AUC value of frequency of blink in looking at a specific stimulating picture could be above 0.8, and the AUC value of X axis diameter of pupil size could be above 0.7. Conclusion The accuracy of eye movement parameters in distinguishing the cooperation or disguise of patients with mental disorders caused by craniocerebral trauma is related with the stimulating picture. The accuracy of frequency of blink in distinguishing cooperation and non-cooperation is better than that of other eye movement parameters.

PURPOSE: The purpose of this study is to determine whether there is any change in the empathy scores of third-year medical graduate students after they have taken a clerkship and have begun gaining more opportunities to meet patients through the clerkship. METHODS: The participants were 109 third-year students in 2014 and 110 fourth-year students in 2015 at Kyungpook National University, School of Medicine. The author measured empathy using a modified and expanded version of the Korean version of the Jefferson Scale of Empathy of Physician Empathy-Student version and used the Holland-III aptitude test-S to assess vocational aptitude. RESULTS: As a results, male students in their third year exhibited higher scores, but there was no significant difference in the fourth year. The empathy score increased slightly when third-year students became fourth-year students, but the difference was not statistically significant. There was no statistically significant change in the scores of both male and female students between the 2 years. The results of the vocational aptitude test showed that students who preferred person-oriented specialties had higher empathy scores when they entered their fourth academic year compared to objectively-oriented students. CONCLUSION: In this study, male students showed higher empathy scores than female students, an atypical finding that was inconsistent with the results of previous studies. However, the distribution of scores among male students was wider than that of female students, a finding consistent with previous studies. As such, individual differences need to be considered when developing curriculum in order to improve the empathy of medical students.

OBJECTIVE: Alcohol-induced blackout (blackout) is a typical early symptom of cognitive impairment caused by drinking. However, the first onset age of blackout or the duration after onset of blackout has not been directly compared in previous studies. The purpose of this study was to investigate the differences in cognitive function to the first start age of blackouts and their duration. METHODS: Thirty-one male subjects were included in this study. Their age at the first blackout and the duration after the onset of blackout were investigated. Neuropsychological tests were conducted to determine their attention, memory, and executive function. Subjects were divided into three groups according to their age of the first onset blackout (group O1, < 20 years; group O2, 21–39 years; and group O3, > 40 years). Subjects were also divided into three groups by duration after the onset of blackout (P1, < 10 years; P2, 10–29 years; and P3, > 30 years). We then examined differences in neurocognitive function among these groups. RESULTS: O1 tended to have a lower memory score than O2 (F = 3.28, p = 0.053). Significant differences were observed in attention and executive function between groups P1 and P3 (Digit Span_backward: F = 6.07, p < 0.05; visual span_forward: F = 4.19, p < 0.05; executive intelligence quotient: F = 3.55, p < 0.05). CONCLUSION: Greater memory impairment was detected in subjects having an earlier age of the first blackout. The longer the duration after the onset of blackout, the more impaired their attention and executive function skills.

BACKGROUND: In this study, we aimed to identify cognitive function and neuropsychological comorbidities in children with newly diagnosed idiopathic epilepsy. METHODS: We retrospectively reviewed the records of 97 antiepileptic drug-naïve children (9.7 ± 2.9 years; 54 males and 43 females) with newly diagnosed idiopathic epilepsy, all of whom underwent a neuropsychological battery. The battery consisted of the Korean Wechsler Intelligence Scale, Attention Deficit Hyperactivity Disorder (ADHD) Rating Scale, ADHD Diagnostic System, Children's Depression Inventory, and State-Trait Anxiety Inventory for Children. We investigated association between scores of the neuropsychological battery and epilepsy classification, lateralization of interictal epileptiform discharges (IEDs) on electroencephalography (EEG), and variables related to seizures. RESULTS: Thirteen patients (14.3%) had ADHD symptoms. Three patients (4.1%) had depressive symptoms, and 9 (12.3%) had anxiety symptoms. Patients with idiopathic generalized epilepsy (IGE) had significantly lower full-scale intelligence and performance intelligence quotient scores than patients with idiopathic localization-related epilepsy (ILRE) (89.0 ± 17.6 vs. 96.3 ± 14.8; P = 0.030 and 88.9 ± 16.3 vs. 97.0 ± 16.4; P = 0.016, respectively). Patients with ILRE having unilateral IEDs had significantly higher full-scale intelligence quotient scores than patients with ILRE having bilateral IEDs and patients with IGE (99.9 ± 12.2 vs. 93.7 ± 16.1 vs. 89.0 ± 17.6; P = 0.039, respectively). CONCLUSION: Our results suggest that idiopathic epilepsy may be accompanied by various neuropsychological comorbidities even at initial diagnosis. Patients with IGE and ILRE having bilateral IEDs on EEG appear more likely to be at high risk of decreased cognitive function.

PURPOSE: The aim of this study was to investigate the safety and the effects of elevated doses of solifenacin and trospium on cognitive function and health-related quality of life (HRQoL) in elderly women receiving treatment for urinary incontinence. METHODS: The study included 312 women aged 60–83 years (mean age, 69.4 years). All participants had scored at least 24 points on the Mini-Mental State Examination (MMSE) scale, and all of them had been diagnosed with urge urinary incontinence (UUI) or mixed urinary incontinence (MUI). The women were randomly assigned to 3 groups: group A, individuals who were simultaneously administered solifenacin at a high dosage of 20 mg per day and trospium at a high dosage of 60 mg per day; group B, persons taking solifenacin and trospium at the usual dosage of 10 and 30 mg per day, respectively; and group C, persons who received a placebo. Participants’ cognitive status was assessed by the MMSE, Controlled Oral Word Association Test, Wechsler Adult Intelligence Scale-Revised, Wechsler Memory Scale III, Colour Trails Test, and California Verbal Learning Test scales. The HRQoL assessment was performed using the Medical Outcomes Study 36-Item Health Survey. RESULTS: The cognitive function parameters did not differ at the start and end of the study across the groups (P>0.05). Additionally, the cognitive function parameters did not differ significantly within each group between the start and end of the study (P>0.05). The values of most HRQoL parameters regarding the functional state of the lower urinary tract (LUT) after the termination of treatment significantly improved in groups A and B (P < 0.05). A significant correlation between cognitive status and HRQoL or LUT parameters was absent (r < 0.3), while the correlations between HRQoL and LUT parameters were r=0.31–0.83, P < 0.05. CONCLUSIONS: The use of elevated doses of solifenacin and trospium did not increase the risk of cognitive impairment in women with UUI and MUI. The combination of solifenacin and trospium at a double dosage may be recommended to elderly women with treatment-resistant symptoms of UUI and MUI. However, the safety of combining antimuscarinic drugs in women with an increased volume of residual urine requires further study.

OBJECTIVE: This study examined the association between the wave form in quantitative electroencephalography (QEEG) and the cognitive and behavioral characteristics measured by the Korean version of Wechsler Intelligence Scale for Children 4th edition (K-WISC-IV), Korean version of the attention deficit/hyperactivity disorder Rating Scale (K-ARS), and Korean version of Child Behavior Checklist (K-CBCL) in children diagnosed with ADHD. METHOD: A retrospective cross-sectional study was performed on children aged 8 to 13 years, who were diagnosed with ADHD at Samsung Medical Center from November 2011 to March 2017. A total of 57 ADHD children were selected by a medical chart review. Their QEEG findings and psychological test results, including K-WISC-IV, K-CBCL, and K-ARS (n=42), were collected. The QEEG was analyzed by the ranges of Hz: delta (1–4 Hz), theta (4–8 Hz), alpha (8–12 Hz), and beta (12–25 Hz) and transformed to the z-scored relative power. The collected data were analyzed using Pearson and Partial correlation analysis. RESULTS: The Letter-Number Sequencing scores of K-WISC was positively correlated with fronto-central alpha. The hyperactivity/impulsivity scores of K-ARS were positively correlated with the theta/beta ratio. Among the items of K-CBCL, social immaturity was positively correlated with delta and theta, and negatively correlated with alpha. Social competence was negatively correlated delta and theta, and positively correlated with alpha. CONCLUSION: These results suggest that the resting state QEEG results of children with ADHD may reflect their cognitive and behavioral characteristics, especially in working memory/executive function, hyperactivity/impulsivity, and sociality.
