This study compared the neuropsychological performance of two post-stroke groups, one undergoing rehabilitation and the other not receiving any intervention, on the acute and chronic stroke phases, and explored sociodemographic and neurological variables associated with changes in performance over time. Sixty-three adults underwent neuropsychological assessment with the Cognitive Screening Instrument (TRIACOG) less than thirty days after having a stroke and were reassessed three to six months after stroke. Thirty-eight participants did not undertake rehabilitation and twenty-five did physiotherapy and/or speech therapy between the two time points.

Introduction Rapid automatized naming (RAN) is the ability to name, as fast as possible, symbols such as letters, digits and figures. The present study aimed to investigate intragroup performance patterns on RAN tasks in children with attention deficit hyperactivity disorder (ADHD) symptoms alone, children with reading disability (RD) alone and controls with typical development. Methods A total of 216 Brazilian children between 8 to 11 years old were selected from public schools located in two Brazilian capitals, namely Porto Alegre and Belo Horizonte, to participate in the study.

Methods: The present study evaluated the performance of 216 Brazilian children from 3 and 4 grades on "cool" executive function (EF) abilities and phonological processing. The children were divided into three groups: those with ADHD symptoms only, those with RD only, and controls.
Purpose: The study presents the process of developing of an instrument for collective evaluation of reading fluency and comprehension of secondary elementary school students in grades 6-9 and verifies the effect of schooling on performance in the instrument.
Methods: 100 students regularly enrolled in grades 6-9 in secondary elementary public schools participated in the study. The construction of the instrument involved seven steps, with the participation of two judges.
Unlabelled: Memory problems are common in stroke patients, although little is known about how accurately chronic stroke patients can monitor and control memory processes.
Objective: The performance of memory and metamemory in stroke patients and healthy controls were investigated, as well as dissociation between performances.
Methods: 10 adults with right hemisphere lesion (mean [M] age=53.
Unlabelled: Screening instruments are ideal for acute clinical settings because they are easy to apply, fast, inexpensive and sensitive for specific samples. However, there is a need to verify the psychometric properties of screening in stroke patients.
Objective: This study investigated the psychometric properties (methodological procedures) of cognitive screening for patients with cerebrovascular diseases.
This study aimed to develop a short version of an instrument to detect cognitive impairment in stroke patients, investigate which cognitive dimensions best discriminate between stroke patients and healthy adults and to graphically analyze the relationships among the neuropsychological variables and groups. This pilot study included 94 adults (49 post-stroke and 45 neurologically healthy) who answered the Brief Neuropsychological Assessment Battery NEUPSILIN for patients with expressive aphasia (NEUPSILIN-Af) to assess orientation, perception, memory, praxis, executive functions, oral language, and academic achievement (written language and arithmetic). The IRT Rasch model for dichotomous data indicated the exclusion of items that could not be used to discriminate performances.

Introduction: Previous studies have implicated impaired verbal fluency as being associated with anxiety disorders in adolescents.
Objectives: To replicate and extend previously reported evidence by investigating whether performance in phonemic verbal fluency tasks is related to severity of anxiety symptoms in young children with anxiety disorders. We also aim to investigate whether putative associations are independent from co-occurring attention deficit hyperactivity disorder (ADHD) symptoms.
Introduction: According to the literature, children's overall reactivity to stress is associated with their socioeconomic status and family environment. In turn, it has been shown that reactivity to stress is associated with cognitive performance. However, few studies have systematically tested these three constructs together.

Methods: The profiles of six adults with acquired dysgraphia in left- or right-hemisphere strokes were investigated by comparing their performance on word and pseudoword writing tasks against that of neurologically healthy adults. A case series analysis was performed on the patients whose impairments on the task were indicative of acquired dysgraphia.
Background: Anxiety disorders typically begin in childhood and adolescence and predict risk for many problems throughout life. Although some neuropsychological correlates have been described, more research is needed, particularly in adolescents. This study compares neurocognitive characteristics of anxious adolescents with and without comorbidity to externalizing disorders to those of typically developing comparison (TDC) adolescents and adolescents with externalizing disorders alone.

Unlabelled: The role of the right cerebral hemisphere (RH) associated with semantic priming effects (SPEs) must be better understood, since the consequences of RH damage on SPE are not yet well established.
Objective: The aim of this article was to investigate studies analyzing SPEs in patients affected by stroke in the RH through a systematic review, verifying whether there are deficits in SPEs, and whether performance varies depending on the type of semantic processing evaluated or stimulus in the task.
Methods: A search was conducted on the LILACS, PUBMED and PSYCINFO databases.
Neuropsychological assessment reveals that certain cognitive changes that take place during the neural development process may be associated with biopsychosocial issues. A substantial body of research has focused on cognitive development in children and adults, but few such studies have been carried out on adolescents. Therefore, research into the processing of neuropsychological functions in adolescents, taking into account the role of major socio-cultural factors such as school type (public vs.
