Uvod: Prefrontalni asocijativni korteks je sjedište izvršnih funkcija ("executive functions") među kojima je ipažnja. Preko talamičke radijacije i pedunculi thalami anterior, talamus je u značajnoj mjeri povezan sa čeonimrežnjem i zonama koje regulišu izvršne funkcije i pažnju. Cilj ovog rada je bio da se ispita uloga talamusa ukontroli i modulaciji psihičke funkcije pažnje posmatranjem korelacije veličine talamusa i intenzitetapsihopatoloških fenomena kod pacijenata sa poremećajem pažnje i hiperaktivitetom odraslih (ADHD) (F90.0).Ispitanici i metode: Istraživanje je obuhvatilo ukupno trideset i jednu osobu oboljelu od poremećaja pažnje ihiperaktiviteta odraslih (ADHD). Dijagnoza poremećaja pažnje je postavljana na osnovu DSM-V kriterijuma, aintenzitet pormećaja je procjenjivan primjenom skale za procjenu intenziteta poremećaja pažnje i hiperaktivitetaodraslih (Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist). Veličina talamusa određivana je naaksijalnim nekontrasnim CT snimcima na površini najvećeg poprečnog presjeka primjenom AutoCAD 2007digitalne morfometrije. Statistički podaci su obrađivani u SPSS 16.0 programskom paketu. Statistički zaključciizneseni su na osnovu dvosmjernog p < 0.05. Rezultati: Uočili smo negativnu korelaciju površine najvećegpoprečnog presjeka talamusa lijevo i intenziteta poremećaja pažnje (regresioni koeficijent B = -0.042, p =0.009). Negativna korelacija površine najvećeg poprečnog presjeka talamusa i intenziteta poremećaja pažnjeuočena je i na desnoj hemisferi mozga (regresioni koeficijent B = -0.027, p = 0.012). Ispitivanjem povezanostiobima presjeka talamusa i intenziteta poremećaja pažnje, nije uočena statistički značajna korelacija obostrano(p > 0.05). Zaključak: Rezultati našeg istraživanja ukazuju da je veći intenzitet poremećaja pažnje bio udružensa manjim presjekom talamusa. Nalazi u literaturi koji negiraju takvu povezanost obavezuju nas na istraživanjesuptilnijih mehanizama regulacije psihičke funkcije pažnje od strane talamusa i drugih regiona mozga.

The aim of the research is to explore the psychometric characteristics of the Serbian adaptation of the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist and Screener, as well as the Adult ADHD Self-Report Screening Scale for DSM-5 (ASRS-5). In addition to these scales, the Depression Anxiety Stress Scale-21 (DASS-21), Dickman Impulsivity Inventory (DII) and the questions about frequency of risky behaviours (use of alcohol, cigarettes and drugs, overeating, and physical aggression) were administrated on the sample of 226 adults from the general population (43.8% males). The results of confirmatory factor analysis supported the one-factor structure of the ASRS-5. The three-factor structure had the best fit indices for the ASRS-v1.1 Symptom Checklist (inattention, hyperactivity, and impulsivity factors), while the two-factor structure was the best for the ASRS-v1.1 Screener (inattention and hyperactivity factors). However, there was a large profile similarity between factors, which calls into question their discriminant validity. All scales correlated significantly with dysfunctional impulsivity and aspects of psychological distress, with ASRS-5 having the largest number of correlations with risky behaviours. There were no sex differences, and correlations with age were negative. It can be concluded that, although all scales show satisfactory psychometric characteristics, ASRS-5 is the preferred one, given its clear one-dimensional structure and somewhat better validity.

Objectives: (a) Evaluate the efficacy and duration of effect of lisdexamfetamine dimesylate (LDX) in adult ADHD. (b) Assess the reliability and validity of the Adult ADHD Medication Smoothness of Effect Scale (AMSES) and Adult ADHD Medication Rebound Scale (AMRS). Method: Adults ( N = 40) with ADHD were treated with LDX for up to 12 weeks. The primary efficacy measure was the ADHD Rating Scale (ADHD-RS). The psychometric properties of the AMSES and AMRS are analyzed and compared with the ADHD-RS, ADHD Self-Report Scale (ASRS) v1.1 Symptom Checklist, and Time-Sensitive ADHD Symptom Scale (TASS). Results: ADHD-RS scores were significantly improved with LDX. The AMSES and AMRS had high internal consistency and were correlated with the ADHD-RS, ASRS v1.1 Symptom Checklist, and TASS. Conclusion: LDX is effective in treating adult ADHD and has a smooth drug effect throughout the day with limited symptom rebound. The AMSES and AMRS are valid and reliable measures.

AbstractAlthough attention deficit hyperactivity disorder (ADHD) in adulthood is associated with marked cognitive impairment, research on metacognition in adult ADHD is scarce. Deficits in metacognition may have a negative impact on treatment adherence, functional outcomes, and everyday life. This study explores metacognition, specifically self-awareness of cognitive performance, in adults with ADHD by combining objective and subjective assessments. Forty-seven patients with ADHD and 47 control individuals completed a neuropsychological assessment battery including tests for attention, executive functions and memory (objective assessment), as well as questionnaires for cognitive functioning and symptom severity (subjective assessment; self- and informant-report). Participants evaluated their test performance of the objective assessment after test completion by selecting a percentile rank which was subtracted from their normed test result, yielding a discrepancy score. Compared to controls, adults with ADHD showed impairments in attention (medium effects) and memory (small and medium effects), but not in executive functions. The discrepancy scores between self-evaluation and cognitive performance revealed deficits in self-awareness of attentional functions (small effects), but not in executive functions and memory in patients with ADHD compared to controls. Discrepancy scores between self- and informant-reports of cognitive functioning revealed no significant differences. Adults with ADHD show impairments in metacognition in attentional functions, but may have intact metacognitive abilities in other domains. Patients with ADHD tend to overestimate their abilities, especially in attentional functions. Subjective and objective measures of metacognition may not correspond, highlighting the need for clinicians to not solely rely on patients’ self-report in their assessment.

Background: There has been marked rise in use of internet over the last decade, with increasing internet use people are more prone to psychological disorders. This has markedly hit the population of young adults as they are the ones who maximum use internet. These users are also prone to develop Attention deficit hyperactive disorder(ADHD) and other behavioural problems.Methods: The study was conducted by the Department of Psychiatry, 900 (design effect=2) students were randomly selected (620 from Medical College and 280 from Dental College). Out of 900, 618 students answered the questionnaire completely which included Young’s Internet Addiction Test (IAT) and the Adult ADHD Self-Report Scale (ASRS-v1.1). Subjects who came positive for ASRS were asked to undergo a test for DSM-V. Independent t-test was used to assess the outcomes and p<0.05 was considered significant.Results: The mean age of the participants were 20.03±1.45 years. It was found that people from age group 19-20 were addicted the most (240 students), coming next were from age group 21-22 (162 students). The prevalence rate of self-reported ADHD symptoms using the ASRS screener was 20.2%. Out of these ADHD suspects 39(31.45%) were moderately addicted and 73(58.87%) were mildly addicted, and this association was found to be statistically significant (p<0.001).Conclusions: Thus, with modernization it is seen that internet use has dramatically increased, which has various kinds of behavioural, psychological, mental effects on one's life. Moreover, students who were more addicted to internet were found to be more susceptible to ADHD.

Abstract. The Pediatric Symptom Checklist-Youth self-report (PSC-Y) is a 35-item measure of adolescent psychosocial functioning that uses the same items as the original parent report version of the PSC. Since a briefer (17-item) version of the parent PSC has been validated, this paper explored whether a subset of items could be used to create a brief form of the PSC-Y. Data were collected on more than 19,000 youth who completed the PSC-Y online as a self-screen offered by Mental Health America. Exploratory factor analyses (EFAs) were first conducted to identify and evaluate candidate solutions and their factor structures. Confirmatory factor analyses (CFAs) were then conducted to determine how well the data fit the candidate models. Tests of measurement invariance across gender were conducted on the selected solution. The EFAs and CFAs suggested that a three-factor short form with 17 items is a viable and most parsimonious solution and met criteria for scalar invariance across gender. Since the 17 items used on the parent PSC short form were close to the best fit found for any subsets of items on the PSC-Y, the same items used on the parent PSC-17 are recommended for the PSC-Y short form.
