“…In this regard, our sample significantly differs from stroke studies carried out in Europe and North America. Conversely, it is in line with neuroepidemiological studies from Brazil and other developing countries 27,28 . This aspect highlights the need for local studies, and a more critical view of overseas studies.…”

“…As we also excluded patients with aphasia due to its influence on cognitive tests that are based on verbal skills, patients with right hemisphere lesions were overrepresented in our sample, limiting the generalizability of the current findings. It is worth mentioning that laterality may affect the efficiency of cognitive functions 27 . Formal education is an important variable to be considered in the evaluation of cognitive functions, especially in the elderly population [18][19][20] .…”

Purpose To investigate potential associations among executive, physical and food functions in the acute phase after stroke. Methods This is a cross-sectional study that evaluated 63 patients admitted to the stroke unit of a public hospital. The exclusion criteria were other neurological and/or psychiatric diagnoses. The tools for evaluation were: Mini-Mental State Examination and Frontal Assessment Battery for cognitive functions; Alberta Stroke Program Early CT Score for quantification of brain injury; National Institutes of Health Stroke Scale for neurological impairment; Modified Rankin Scale for functionality, and the Functional Oral Intake Scale for food function. Results The sample comprised 34 men (54%) and 29 women with a mean age of 63.6 years. The Frontal Assessment Battery was significantly associated with the other scales. In multivariate analysis, executive function was independently associated with the Functional Oral Intake Scale. Conclusion Most patients exhibited executive dysfunction that significantly compromised oral intake.

“…It is important to note that, although sensitivity levels were 7% greater in right-handers, the difference was non-significant. This finding supports previous results that left-handers represent a more heterogeneous population in terms of cerebral lateralization for handedness [65, 66]. …”

Using Bishop’s Card Reaching Task to Assess Hand Preference in 8- to 10-Year-Old Czech Children

2016

Hand preference is one of the most apparent functional asymmetry in humans. Under contralateral control, performance is more proficient with the preferred hand; however, the difference between the two hands is greater in right handers, considering left handers generally display less cerebral lateralization. One method of evaluating hand preference is Bishop’s card reaching task; however, information regarding validity and sensitivity with children in limited. This study assessed the relationship between Bishop’s card reaching task and five hand preference tasks in 8- to 10-year-old typically-developing children from the Czech Republic (N = 376). Structural equation modelling identified a one factor model as the most suitable, including Bishop’s card reaching task and three hand preference tasks (ringing, throwing, and rolling with dice). The factor validity (.89) and sensitivity of Bishop’s card reaching task (90% to 97%) provided a very good identification of hand preference. These results support the suitability of Bishop’s card reaching task as a separate test for determining hand preference in children. Accordingly, we suggest that the assessment of handedness, particularly in neurodevelopmental disorders where the proportion of right-handers and left-handers is disrupted (e.g., children with DCD or ADHD), should make use of Bishop’s card reaching task alongside other unimanual tasks.

“…Functional cerebral asymmetries (FCAs) have been observed in all vertebrate classes [43,81,82,95,108,116] and are of central importance for the functional organization of several cognitive systems in the human brain [80]. While some authors assume that FCAs are mostly determined by genetic factors [2] and thus should be constant over time, evidence is accumulating that FCAs are to some extent plastic and can change over the lifetime of an individual as well as within shorter timeframes [89].…”
