Full textAbstract:
Introdução: Prejuízos na atenção, concentração e execução de tarefas, entre outras funções cognitivas, parecem ser frequentes em doentes com câncer e em cuidados paliativos e podem comprometer o cotidiano desses pacientes. No entanto, há poucos estudos sobre o tema e desconhecem-se testes validados para essa população no Brasil. Objetivo: Validar o Teste de Trilhas B (TT-B) para uso em pacientes com câncer em cuidados paliativos. Método: Trata-se de estudo metodológico, de validação de instrumento, que envolveu pacientes (n=94) em tratamento paliativo no Ambulatório de Quimioterapia do Instituto do Câncer do Estado de São Paulo e seus acompanhantes (n=39). Os avaliados realizaram o TT-B e responderam dados sócio-demográficos, sobre a presença e intensidade de dor, de fadiga, sobre a qualidade do sono, ansiedade e depressão, em dois momentos, com intervalo máximo de sete dias. Os doentes também foram caracterizados quanto à doença e tratamento. As validades convergente e divergente foram testadas pela correlação entre o desempenho no TT-B, mensurado pelo tempo para a realização do teste e o número de erros cometidos, com a intensidade da dor, da fadiga, da ansiedade, da depressão e do repouso atribuído ao sono da noite anterior às avaliações. A validade discriminante foi testada pela comparação do TT-B entre doentes e sadios. A estabilidade do TT-B, em doentes e sadios, foi avaliada por meio de teste e reteste. Resultados: Os doentes tinham câncer colo-retal (47,8%), câncer de mama (15,9%), a totalidade apresentava metástase, foram homens (52,1%), com idade média de 53 anos. Para os doentes, o tempo médio de realização do TT-B foi de 147,5 segundos na primeira e 132 segundos na segunda avaliação e o número de erros médio foi de 1 na primeira e 0,8 na segunda avaliação. Para os acompanhantes o tempo de realização do TT-B foi de 127,3 e 110,7 segundos na primeira e segunda avaliação respectivamente e o número de erros foi 0,9 na primeira e 0,6 na segunda avaliação. O instrumento discriminou doentes de sadios em relação ao tempo utilizado para a realização do teste na primeira (p=0,014) e na segunda (p=0,035) avaliação, indicando melhor desempenho para os sadios, mas não em relação ao número de erros. O teste foi estável entre os sadios nas duas avaliações, tanto em relação ao tempo (p=0,071) quanto em relação ao número de erros (p=0,352) e entre os doentes o instrumento foi estável apenas em relação ao número de erros (p=0,913). O TT-B não demonstrou correlações significativas com dor, fadiga, depressão, ansiedade e descanso, o que causou estranheza. Conclusão: O TT-B está em processo de validação. Mostrou-se capaz de discriminar doentes de sadios e foi estável entre os saudáveis. Recomenda-se a continuidade de estudos com amostras maiores e a utilização do TT-B em paralelo a outro instrumento que avalie a função executiva.<br>Introduction: Impairments in attention, concentration and execution of tasks, among other cognitive functions, seem to be frequent in patients with cancer in palliative care and they can affect patients daily life. However, there are few studies about the theme and to our knowledge there are no validated tests for this population in Brazil. Objective: To validate Trial Making TestB (TMT-B) for assessment of patients with cancer in palliative care. Methods: Methodological study to validate an instrument that involved patients (n=94) in palliative treatment at the Clinic of Chemotherapy of the Instituto do Câncer do Estado de São Paulo and their healthy accompanying person (n=39). Patients were tested on TMT-B and answered demographic data, questions about the presence of pain and intensity, fatigue, quality of sleep, anxiety and depression, in two moments, with maximum interval of seven days. The patients were also characterized according to disease and treatment. The convergent and divergent validities were tested by the correlation between the performance on TMT-B, measured by the amount of time required to complete the task and the number of mistakes, and pain intensity, fatigue, anxiety, depression and the rest attributed to sleep in the previous night before assessments. The discriminate validity was tested by the comparison of TMT-B between patients and healthy accompany persons. The stability of TMT-B, in patients and healthy companions was evaluated through test and re-test. Results: The patients had colorectal cancer (47.8%), followed by breast cancer (15.9%), the totality presented metastasis, most patients were men (52.1%), mean age was 53 years. For patients, mean time required to complete TMT-B was 147.5 seconds in the first and 132 seconds in the second assessments and the mean number of mistakes was 1 in the first and 0.8 in the second assessments. For the healthy accompany person, the time required to complete TMT-B was respectively 127.3 and 110.7 seconds in the first and second assessments and the number of mistakes was 0.9 in the first and 0.6 in the second assessments. The instrument discriminated patients from healthy accompany persons regarding time required to complete the test in the first (p=0.014) and second (p=0.035) assessments, indicating better performance for the healthy ones, but not in relation to the number of mistakes. The test was stable among healthy people in the two assessments regarding time (p=0.071) and number of mistakes (p=0.352); for patients, the instrument was stable only in relation to the number of mistakes (p=0.913). TMT-B did not demonstrate significant correlations with pain, fatigue, depression, anxiety and rest. Conclusion: TMT-B is in validation process. It was able to discriminate between patients and healthy accompany persons and was stable for the healthy ones. Further studies are recommended with larger samples as well as the use of TMT-B in parallel to other instrument that evaluates the executive function.

Full textAbstract:
This study examined the utility of the Trail Making Test Quotient (Trails B/ Trails A) in assessing executive functioning relative to that of common tests of executive function such as the Wisconsin Card Sorting Test, Category Test, and the Stroop Test. The purpose of the current study was to investigate the relationship of the Trail Making Test Quotient (Trails B/ Trails A) with other common tests of executive functioning (i.e., Wisconsin Card Sorting Test, Stroop, Category Test) to determine whether these tests are measuring similar domains of functioning or whether Trail Making Test Quotient (Trails B/ Trails A) offers a more pure measure of executive functioning over and beyond that of Trail Making Test B alone or the difference score, Trail Making Test (Trails B- Trails A).
A series of partial correlations were conducted involving the Trail Making Test scores (Quotient, Difference, and B [Raw]), and the scores of the executive functioning measures (Wisconsin Card Sorting Test, Category Test, and Stroop), controlling for age, education, and gender. Trails Quotient, Trails B Raw, and Trails Difference were found to significantly negatively correlate with WCST Total # of Categories. Only Trails B Raw and Trails Difference were found to significantly positively correlate with WCST Perseverative Responses and Category Error. None of the Trail Making Test measures used in this study were found to significantly correlate Stroop Interference. Correlation coefficients were compared to determine the strength of Trails Quotient's relationship with
the aforementioned executive functioning measures relative to that of Trails Difference and Trails B Raw.
Contrary to the hypotheses of the current study, the Trails Quotient demonstrated a significantly weaker correlation with WCST Total # of Categories, WCST Perseverative Responses, and Category Error than that of Trails Difference and Trails B Raw. Additionally, there were no significant differences in the correlation coefficients of Trails Quotient, Trails Difference, and Trails B Raw with Stroop Interference. However, upon further investigation using exploratory factor analyses, it was discovered that Trails Quotient may have represented a particular component of executive functioning more so than the Trails Difference and Trails B Raw. The results suggest that Trails Quotient offers a unique estimate of executive skill specific to cognitive organization, whereas Trails B Raw and Trails Difference represent multiple executive domains including regulatory and organizational abilities.
Clinical practice will benefit from the current study's findings in that assessment of complex executive functioning will be more precise. Future research is needed to determine the utility of the Trails Quotient in identifying specific types and locations of brain injury. Assessment of specific impaired frontal skills common to degenerative dementias and traumatic brain injury may be possible with the use of Trails Quotient contingent upon further research. Future research into the domains of executive functioning and the Trail Making Test should focus on specific skills within regulatory and organizational components, and the development of normative data for Trails Quotient.

Full textAbstract:
La notion de "fonctions exécutives" est complexe et revêt de multiples dimensions. Pour mesurer de façon objective et reproductible ces fonctions, nous disposons d'outils dont le Trail Making Test (TMT) est un exemple. Afin d'appréhender les performances au TMT dans ses deux formes A et B, les cliniciens s'appuient sur les indices B-A ou B/A, supposés refléter le poids du processus d'alternance. L'objectif de notre étude est d'une part, de vérifier la validité de l'utilisation du TMT en pratique clinique à partir de l'indice B-A, et d'autre part, d'évaluer si le procesus d'alternance est le seul impliqué dans cette épreuve. Les résultats montrent que l'indice B-A ne permet pas d'évaluer de manière univoque le coût de l'alternance entre les deux lexiques impliqués et ceci pour trois raisons : les différences de longueur et d'organisation spatiale entre les parties A et B du TMT ont un effet sur les temps de réalisation, au détriment de la partie B. De plus, le type de lexique influence les performances, le lexique alphabétique étant plus long d'accès que le lexique numérique. Enfin la partie B du TMT apparaît multifactorielle : les performances à cette épreuve sont liées aux performances à différentes tâches évaluant des aspects distincts de l'administrateur central. Celui-ci semble jouer un rôle important dans la recherche en mémoire à long terme impliquée par l'accès au lexique alphabétique, alors que la procédure d'alternance semble pouvoir être réalisée sans l'intervention d'un contrôle exécutif<br>The concept of executive functions is complex and includes various aspects. We can use different tools to get an objective and reproductible evaluation of these functions, including the TMT. TMT can be assessed in the two forms, A and B, and psychologists used B-A or B/A indexes which represent the switching procedures. The first aim of our study is to examine the validity of TMT used in clinical practice with the B-A index, and the second objective is to assess if only the switching process is included in this task. Results showed the B-A index does not allow a non equivocal evaluation of the switching cost for three reasons : length and spatial organization between part A and B and lexicon types are sufficient to induce significant time differences in test performances, affecting more the part B. In addition the type of lexicons influences the performances. TMT part B performances are linked to task, exploring various components of the CE. Central Executive seems to have an important part in long term memory research associated with alphabetical lexicon access whereas switching operation could be performed without the involvement of an executive control

Includes bibliography.<br>This study provides a provisional normative range of performance for the South African semi- and unskilled black and coloured population groups on the Trail Making Test. One hundred and six black and coloured semi- and unskilled workers from the Groote Schuur Hospital in Cape Town, satisfying the criteria of 8 years or less of formal education, with no neurological impairment or psychopathology, and some degree of literacy, were randomly selected. Parts A and B of the Trail Making Test were then administered and scored, and the scores reported in tabular form, broken up in terms of race, age and education. A statistical analysis (multiple linear regression) was applied to the data and additional information on the effects of age, education and sex on test performance briefly discussed in terms of previous research findings. The results of this study add weight to Dugmore's (1987) assertion that existing norms currently in use for the Trail making Test are invalid for these population groups. Limitations of the study and suggestions for further research were also briefly discussed.

Full textAbstract:
Numerous studies have suggested that neuropsychological test performance is affected by demographic variables such as age and education. This study examined the effects of age and education on the Trail Making Test, the Digit Symbol Sub-Test, and the Finger Tapping Test in a non-clinical sample of community dwellers with a relatively low level of education (8 to 12 years) in South Africa. The sample consisted of 161 participants across six age groups: 20-39, 40-59, 69-69, 70-79, 80-89 and 90-95 years. Results were examined for mean age effects and variability trends. Highly significant age effects were present across the age groups for all tests, however, there was no uniform pattern of variability across the tests. The Digit Symbol Substitution Test and the Finger Tapping Tests showed a pattern of increasing variability with increasing age, followed by a decrease in very old age while no trend was evident for the Digit Symbol extensions (the Immediate and Delayed Recall tests). The Trail Making Test, Parts A and B, showed a consistent trend of increasing variability across the age groups. Data from the present study was compared with existing data from two relatively high education samples, with equivalent age groupings, to examine education effects. Results showed an education effect for all tests with the high education groups outperforming the low education groups. Although the effects of education became less potent with advancing age, the mean performance of the oldest (80-89 years) high education age group was superior to that of the equivalent low education age group. Comparison of variability trends across both samples showed that the highest variability (the shuttle bulge) was present at the same point along the age axis, or at a later point, for the low education group, as that for the high education group. This finding is inconsistent with Jordan's (1997) 'shuttle model of variability' which predicts an earlier occurrence of the shuttle bulge (left shuttle shift effect) for a low education sample. This study demonstrated that performance on neuropsychological tests is influenced by age and education and highlighted the dangers inherent in unquestionably applying norms, which have not been corrected for age and education, when assessing the older adult.

Thesis, Linköpings universitet, Institutionen för datavetenskap, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-141836.
Full textAbstract:
In this thesis, the relationship between cognition and speech-in-noise recognition, in normally-hearing Swedish students, is examined. The Trail Making Test, hypothesized to measure a wide range of cognitive functions, including executive function and working memory, has been criticized for being a culturally biased measure, hence the need for a culturally unbiased version. A between-group experiment was conducted in which a non-semantically dependent version of the Trail Making Test was compared to the original Trail Making Test in order to test for psychometric equivalence. A total of 21 young normally-hearing Swedish students were given three tests: TMT or TMT (non-semantically dependent version), a Swedish Reading Span Task and a Swedish speech-in-noise recognition task. The B parts of the two Trail Making Test versions differed significantly and both were moderately to highly correlated to speech-in-noise and reading span performance. The results indicates that the original Trail Making Test is a more plausible index for executive function and strengthens the relationship between executive function, working memory and speech-in-noise recognition.

The aim of the study was to produce preliminary normative indications for the Trail Making Test and the Stroop Test, administered in English, on a non-clinical sample of black, Xhosa-speaking, unskilled individuals (N = 33), with an educational level of 11 – 12 years, in two age categories (18 –29 and 30 – 40 years). The sample was equally distributed for gender and level of education. Participants, who were required to have a basic proficiency in English, were from traditionally black township schools with relatively disadvantaged quality of education. Within-sample age and gender effects were investigated. There were no significant age effects on the Trail Making Test, whereas there was one significant difference between age groups on the Stroop Test with respect to the Color-Word task, and a result that strongly approached significance on the Word task, with the younger group performing better than the older group. There were no significant gender effects on the Trail Making Test, whereas there was one significant difference between genders on the Stroop Test with respect to the Word task, and a result that approached significance on the Color task, with females performing better than males. Normative indications for both measures were compared to available normative data on western populations with higher levels and more advantaged quality of education. This comparison revealed consistently poorer performances for both the Trail Making Test and the Stroop Test, confirming the need for localised normative datasets to facilitate accurate neuropsychological diagnoses on culturally disadvantaged individuals.

Full textAbstract:
Mild Cognitive Impairment is a condition that affects an individual's thinking and decision making capabilities. Specifically, it is one where an individual's capabilities of memorizing, thinking and decision making are less efficient when compared to others. In order to diagnose this condition, a conventional method is to provide the subject with a small challenge they should be completed using pen and paper. This thesis focuses on how this method can be converted to a computer based test. A data visualization tool named Processing has been used to develop a system that runs a game-like test, which is completed by individuals using a mouse. The system then saves the individual's mouse movements in the form of a CSV file. This files are used for further analyzed using JMP Pro on how this data can be used for determining cognitive abilities via computing a metric called Fractal, and what conclusions can be drawn. In order to achieve comparable results, readings from two diverse age groups have been collected. The results using a total of 12 subjects are convincing in that the tool can be used to as a marker for detecting cognitive impairment.

This dissertation examines predictors of juror-determined damage awards among 377 juror eligible mock jurors. Citizens reporting for jury duty in a large metropolitan county on five days when the study was conducted were invited to participate. Scenarios were created that varied both case facts and witness emotion during trial testimony. Results indicate that Affect Control Theory can be applied to the situation of juror-determined damage awards and is helpful in scientifically explaining some of the variation of both compensatory and punitive damage awards.

Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>A população de idosos cresce rapidamente no Brasil. A prevalência de hipertensão arterial sistêmica (HAS) e distúrbios cognitivos é elevada nesta população. Testamos a hipótese de que a HAS reduz o desempenho cognitivos em idosos. Foram selecionamos idosos hipertensos e normotensos com idade ≥ 60 < 80. O desempenho cognitivo foi avaliado pelo Cambridge Cognitive Examination Revised (CAMCOG-R), por subtestes do Wechsler Adult Intelligence Scale v.3 (WAIS III), além do Rey Auditory Verbal Learning Test (RAVLT), e o dos Trail Making Tests A/B (TMT-A/B). O desempenho cognitivo avaliado pelo escore global do CAMCOG-R e do QI estimado do WAIS III está reduzido nos idosos hipertensos mesmo quando controlado pela escolaridade, depressão, estado geral de saúde e qualidade de vida. O desempenho cognitivo em diversos domínios específicos controlados para a escolaridade, depressão, estado geral de saúde e qualidade de vida, e avaliados pelo CAMCOG-R, WAIS III, TMT-A e RAVLT também está reduzido nos idosos hipertensos. O presente estudo sugere que a HAS está associada ao declínio do desempenho cognitivo global em idosos. Notadamente, o desempenho das funções executivas está reduzido nos idosos hipertensos. Especula-se que a HAS seja um fator de risco para o declínio progressivo do desempenho cognitivo e, portanto, para o desenvolvimento de demência.<br>The elderly population is growing rapidly in Brazil. The prevalence of hypertension and cognitive disorders is high in this population. We tested the hypothesis that hypertension is associated with decreased cognitive performance in the elderly. We selected normotensive and hypertensive subjects aged ≥ 60 <80 years old. Cognition was assessed through Cambridge Cognitive Examination Revised (CAMCOG-R), subtests of the Wechsler Adult Intelligence Scale v.3 (WAIS III), the Rey Auditory Verbal Learning Test (RAVLT), and the Trail Making Tests A/B (TMT-A/B). The cognitive performance assessed by the CAMCOG-R global score and the estimated WAIS III. QI is reduced in elderly hypertensives even when controlled for education, depression, health status and quality of life. The cognitive performance in diverse cognitive domains assessed through CAMCOG-R, WAIS III, TMT-A e RAVLT is also reduced in elderly hypertensives when contolled for education, depression, health status and quality of life. These results suggest that hypertension is associated with reduced global cognitive performance in eldely hypertensives. Notably, executive functions are reduced in eldely hypertensives. We speculate that hypertension might be a risk factor for the progressive decline in cognitive function and, therefore, for the development of dementia.

Thesis, Linnéuniversitetet, Institutionen för idrottsvetenskap (ID), 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-63849.
Full textAbstract:
Bakgrund: Placebo finns i en mängd olika former, allt från läkemedel till manipulation av utrsutning. Hur placebo fungerar i kroppen är svårt att fastslå, trots detta har positiva effekter påvisats genom minskad kronisk smärta (Finnis et al., 2010), sömnlöshet (Belanger et al., 2007) och depression (Kirsch et al., 2008). Tidigare studier visar även att styrkelyftare ökar sin maximala styrka med hjälp av placebo. Metod: Studien är en cross-over experimentell design där totalt 19 deltagare medverkat. Två stycken kapslar, en på 300 mg och en större på 450 mg används för att se skillnader i ett trial making test och ett beeptest. Syftet med studien är att undersöka och kvantifiera placeboeffekten. Studien baseras på hypotsen att priset på, och mängden av ett placebopreparat påverkar resultatet i ett test för fysisk prestation (beeptest) och i ett test som mäter koncentrationsförmågan (Trial making test). Resultat: Trial making test del a visade ingen signifikant skillnad mellan kapsel a och kapsel b (p=0,699). Trial making test del b rapporterade inte någon signifikant skillnad mellan kapsel a och b (p=0,161). Vid beeptestet rapporterades det även här ingen signifikant skillnad mellan kapsel a och b (p=0.839). Slutsats: Det är svårt att dra en slutsats om vi lyckats övertala deltagarna tillräckligt för att bevisa att en placeboeffekt påverkar resultatet i ett beeptest och i ett trial making test. En annan fråga vi ställer oss är om beeptestet är rätt val av test för att testa placebons effekt eftersom mycket runt omkring kan ha påverkat deltagarna, exempelvis av varandra och hur de presterar. Detta är något som vi tror kan ha påverkat resultatet.

Full textAbstract:
The Aronson Cognitive Residual Evaluation Scale (ACRES) is a new, relatively short neuropsychological test which attempts to measure residual cognitive skills. This study evaluated the ACRES test-retest reliability over a one to twelve month interval. The Trail Making Test (TMT) was included as a validation measure. Subjects were 58 males and females, aged 68 to 94, living in a retirement center or in the community. The ACRES exhibited moderate to strong reliability correlations and the TMT demonstrated low to moderate correlations with the ACRES. There was no time interval effect. Age had a negative effect on four of five ACRES subtests and gender was significant for one ACRES subtest and the TMT Part B. Percent of subjects classified as brain impaired using traditional cutoffs was higher than when age-corrected norms were used. Clinical utility of the ACRES and the TMT is discussed regarding need for age-corrected norms.

L'obiettivo del presente elaborato di tesi è lo studio dell'associazione tra variabili di neuroimaging e variabili neuropsicologiche, tramite analisi statistiche, con particolare attenzione agli indici strutturali in grado di interpretare i punteggi di test neuropsicologici ottenuti da pazienti affetti da deterioramento cognitivo lieve di origine vascolare e patologia dei piccoli vasi cerebrali. I metodi statistici impiegati consistono in analisi di regressione lineare multipla, sviluppati ed automatizzati nel pacchetto SPSS (Statistical Package for Social Science) e classificazione grazie ad algoritmi di machine learning, implementati in ambiente R. Le analisi sono state applicate ad un dataset costituito da 64 pazienti inclusi nel progetto VMCI-Tuscany. Le analisi di regressione e classificazione sono state applicate a tre modelli diversi, in funzione delle variabili esplicative considerate: il primo modello è costituito da variabili volumetriche, mentre gli altri due modelli includono anche indici di diffusione cerebrale, quali Mean Diffusivity (MD) e Fractional Anisotropy (FA). I risultati evidenziano l'importanza dell'indice di diffusione MD della sostanza bianca come predittore significativo del deterioramento cognitivo: in particolar modo la sostanza bianca apparentemente normale e la sostanza bianca totale presentano MD simili, mostrando, come, in questa coorte di pazienti, la segmentazione semi-automatica delle lesioni non sia necessaria. L'applicazione di tecniche di machine learning al test MoCA permette di ottenere un coefficiente di correlazione di Pearson tra i punteggi osservati e quelli stimati dall'algoritmo di Support Vector Machine pari a 0.62. I risultati migliori delle analisi di classificazione, invece, corrispondono a valori di sensibilità e di specificità pari al 71.44% e al 80.56% per il test MoCA e valori di sensibilità e di specificità pari al 71.79% e al 72% per il test TMT-A.

Full textAbstract:
The 85th percentile off-road glances while performing three tasks on an in-vehicle system while driving in a simulator was investigated. The tasks were a radio task, a telephone task and a sound settings task which were performed at three occasions each. The distribution of 85th percentile off-road glance durations for each subject and task showed that durations differed between individuals rather than between tasks. It also turned out that durations longer than 2.00 seconds were not rare and 2 of 16 subjects had durations longer than 2.00 seconds in the radio task. Even though the distribution showed small differences between tasks on an individual level, differences on a group level were found between the tasks. A tendency of a learning effect was found, which implied a decrease in 85th percentile off-road glance durations as the tasks were performed at several occasions. A tendency of a floor effect in 85th percentile off-road glance durations, when the subjects are familiarized with tasks, was also found. Performance on a computerized trail-making test, measuring ability of visual search, motor speed and mental flexibility, was found not to be related with 85th percentile off-road glance durations.

INTRODUÇÃO: A Estimulação Magnética Transcraniana repetitiva (EMTr) é uma técnica que possibilita a aplicação de campos magnéticos com capacidade excitatória ou inibitória, em determinadas áreas corticais e sub-corticais adjacentes, facilitando a compreensão da relação existente entre a cognição e o córtex (funções executivas e áreas corticais específicas) podendo essa avaliação ser efectuada através de testes neuropsicológicos.
OBJECTIVOS: Através da aplicação do Trail Making Test e do Teste Stroop de Cores e Palavras, realizados em duas fases, antes e após uma sessão de EMTr, pretendeu-se recolher dados normativos para uma amostra de adultos jovens e comparar os resultados obtidos entre os diferentes grupos de indivíduos, tendo em conta o tipo de estimulação a que foram sujeitos (iTBS excitatória ou cTBS inibitória), comparando os resultados com os obtidos pelo grupo de controlo, submetido a estimulação placebo. Pretende-se também analisar se os resultados são influenciados pelo efeito de género e pela habituação.
MATERIAIS E MÉTODOS: A amostra foi constituída por 40 indivíduos voluntários, saudáveis, com idades compreendidas entre os 18 e os 30 anos, seleccionados através de um inquérito. Foram previamente estabelecidos critérios de inclusão e exclusão. A avaliação neuropsicológica foi efectuada através da aplicação do Trail Making Test e Teste Stroop de Cores e Palavras.
RESULTADOS: Os resultados revelaram existir diferenças estatisticamente significativas entre as médias obtidas nas duas fases de realização da Parte A do TMT e na variável “interferência” do Teste Stroop, resultante da diferença verificada entre os Grupos A (excitatório) e Grupo B (inibitório). Em relação ao género, verificou-se a existência de diferenças estatisticamente significativas nas duas partes do TMT, tendo os elementos do género masculino obtido melhores resultados. Nas variáveis do Teste Stroop, não se observaram diferenças estaticamente significativas.
CONCLUSÕES: Foi possível verificar que uma sessão de EMTr (TBS) – inibitório e excitatória - exerce efeito sobre determinadas funções executivas. Através da aplicação de testes psicológicos em duas fases de avaliação, antes e depois da estimulação, é possível analisar as alterações provocadas. Os resultados sugerem que, quando aplicada uma estimulação inibitória, no hemisfério esquerdo, esta promove a melhoria das funções predominantes no hemisfério direito e, por sua vez, quando a estimulação aplicada no hemisfério esquerdo é de carácter excitatório são impulsionadas as funções dominantes nesse hemisfério.<br>INTRODUCTION: Repetitive Transcranial magnetic stimulation (TMS) is a technique that allows the
aplication of magnetic fields with capacity, excitatory or inhibitory, in certain cortical and
subjacents subcortical areas, facilitating the comprehension of the relationship between
cognition and the cortex (executive functions and specific cortical areas) which can be evaluated
by neuropsychological tests.
OBJECTIVES: Through the application of the Trail Making Test and Stroop Test Color and Word,
conducted in two phases, before and after a session of rTMS, we intend to collect normative data
for a sample of young adults and compare the results between different groups of individuals,
taking into account the type of stimulation to which they are subjected (excitatory iTBS
excitatory or inhibitory cTBS) by comparing the results with those obtained with a control group
subject to placebo stimulation. We also intend to examine whether the results are influenced by
gender.
MATERIALS AND METHODS: The sample was constituted by 40 volunteers, healthy, aged between
18 and 30 years, originally selected through a survey. We previously established criteria for
inclusion and exclusion. The neuropsychological evaluation was carried out by applying the trail
making test and test Stroop Color and Word.
RESULTS: The results revealed a statistically significant difference between the means obtained
in the two phases of implementation of Part A of the TMT and in the Stroop Test interference
variable, resulting from the difference observed between Group A (excitatory) and Group B
(inhibitory). Regarding the gender, observing the existence of a statistically significant difference
in the two parts of the TMT, having the males elements obtained better results.
CONCLUSIONS: A session of EMTr (TBS) - inhibitory and excitatory - has an effect on certain
executive functions. Through the application of psychological tests in two phases of the
evaluation, before and after the stimulation it is possible to analyze this effect. The results
suggest that when applying inhibitory stimulation in the left hemisphere there is an increase in
the functions predominant in the right hemisphere, and in turn, when applying the excitatory
stimulation to the left hemisphere the predominant functions in this hemisphere are improved.

The role of executive functioning in substance dependence and addiction has received
increased attention in recent years; however, the findings of empirical studies are at times
contradictory and difficult to compare at face value. To address the current state of
fragmentation and to delineate the current body of knowledge a systematic review of
existing studies was conducted. The synthesis of the findings from these studies confirmed
that lower neuropsychological performance scores of executive functioning are observed
in substance dependent populations. Furthermore, the synthesis of the components of these
studies provided a comprehensive overview and revealed a number of critical gaps in the
current body of knowledge. The gaps include limitations concerning specific
demographics of the samples studied (under-representation of females, adolescents, the
elderly, individuals with limited education, and individuals from Africa, Oceania, Asia,
Latin America and the Caribbean), as well as the scarce number of studies investigating
specific substances; insufficient longitudinal studies; and the fragmentation of executive
functioning as a theoretical construct.<br>Psychology<br>M.A. (Psychology)

This diploma thesis is introducing Trail Making Test - Part A as a tool for assessment of cognitive deficit in schizophrenia. Cognitive deficit is one of the core symptoms of schizophrenia which plays a key role in the final psychosocial functioning in the life of people with schizophrenia. Therefore, it is important to pay attention to the efficiency of interventions focused on improving cognitive functions and the quality of diagnostics. In this paper we were verifying a validity of TMT-A in use of cognitive deficit in schizophrenia. We have found out that the test discriminates between clinical and healthy population (n=332) quite well. Participants with schizophrenia scored significantly worse than the healthy volunteers in the time variable. We have not found any difference in the number of errors in TMT-A between the groups. In the ROC analysis we were verifying if the TMT-A has enough good sensitivity and specificity and we found positive results. The AUC value was large for the age category of 18-44 as well as for particular age subgroups. Using the regression analysis we controlled for the demographic differences of the clinical and healthy groups and we estimated the difference between the performance of clinical and healthy population of about 11,9 seconds. Due to the general nature of...

Full textAbstract:
Attention is one of the key competencies which has to be adequately developed in preschool children to support their good school adaptation and acceptation of school demands. This work describes current approaches to assessment of attention and related cognitive functions in children at preschool and early school years. On the basis of the methods which are accessible we introduce a new assessment tool, which could serve as screening of attention and other necessary competencies of children aged 5-7 years. The empirical part of this work shows results of a validization study of our method (Coloured trail making test for children), and its reliability the tool. Results proved strong correlations among our method and three other assessment tools from larger batteries of tests (Woodcock - Johnson Tests of Cognitive Abilities, IDS and CAS II). However, the outcomes of the tests are also different enough to conclude that each of four methods which we used can be important in the process of attention assessment in preschool children; and each of these methods can bring valid information about children's abilities. The work also includes normative data for Coloured trail making test for children, which can be used as a screening tool to detect minor difficulties of children's attention or it can help to...
