Using Mahalanobis Distance to Evaluate Recovery in Acute Stroke.
Discussion: In the acute phase of stroke using Mahalanobis distance it is possible to distinguish between recovery, normal learning, and gerneralized learning deficits thereby identifying likely candidates for further cognitive assessment and rehabilitation.

The Role of Apathy and Depression on Verbal Learning and Memory Performance After Stroke.
Conclusions: These results suggest that apathy, not depression, is related to verbal memory performance in stroke patients. Future research should explore whether treatment of apathy (e.g., improving motivation) could be a novel target for improving cognition after stroke. Researchers should also examine whether this model can be applied to other aspects of cognition, including executive function and other areas of memory including autobiographical and working memory.

Children with perinatal stroke are at increased risk for autism spectrum disorder: Prevalence and co-occurring conditions within a clinically followed sample
DISCUSSION: Children with perinatal stroke have an increased prevalence of ASD (11.4%) than in the general population. ASD concerns arise at a similar age as the general population, yet ASD is diagnosed almost two years later than the general population and 3.60 years after first concerns present. Co-occurring neurological conditions are common. Clinicians must be aware of increased prevalence and implement screening as part of routine care for all pediatric patients with perinatal stroke.PMID:34308766 | DOI:10.1080/13854046.2021.1955150

Neuropsychological outcome following thalamic stroke in adolescence: an identical twin comparison.
CONCLUSIONS: These results suggest risk for deficits in encoding of new verbal information following bilateral thalamic stroke in adolescence, as well as risk for persistent cognitive deficits despite initial improvements. This is consistent with descriptions of anterograde memory impairments in adults with similar lesions. PMID: 30472911 [PubMed - as supplied by publisher]

Visual short-term memory and attention: An investigation of familiarity and stroke count in Chinese characters.
Using Chinese characters, we investigated how stroke count and frequency of use influence attention and short-term memory (STM) encoding in Mainland Chinese speakers. To isolate specific components of attention we employed the Theory of Visual Attention (TVA), which allowed estimates of STM capacity, processing speed, and the threshold of visual perception. An analysis of TVA parameters revealed that familiarity affects both the memory capacity and processing speed of objects, whereas the threshold for visual perception remained unaffected. Interestingly, our results also indicate that modulation of attention is driven sol...

The elaboration of motor programs for the automation of letter production.
Abstract We investigated how children learn to write letters. Letter writing evolves from stroke-by-stroke to whole-letter programming. Children of ages 6 to 9 (N=98) wrote letters of varying complexity on a digitizer. At ages 6 and 7 movement duration, dysfluency and trajectory increased with stroke number. This indicates that the motor program they activated mainly coded information on stroke production. Stroke number affected the older children's production much less, suggesting that they programmed stroke chunks or the whole letter. The fact that movement duration and dysfluency decreased from ages 6 to 8, and...

Task-appropriate visualizations: Can the very same visualization format either promote or hinder learning depending on the task requirements?
In a series of experiments, we tested a recently proposed hypothesis stating that the degree of alignment between the form of a mental representation resulting from learning with a particular visualization format and the specific requirements of a learning task determines learning performance (task-appropriateness). Groups of participants were required to learn the stroke configuration, the stroke order, or the stroke directions of a set of Chinese pseudocharacters. For each learning task, participants were divided into groups receiving dynamic, static-sequential, or static visualizations. An old/new character recognition ...

Impairment of brain plasticity by brain inflammation.
The ability to learn and the ability to reshape brain circuits are regarded as some of the most remarkable and important features of the brain. This ability declines with age due to largely unknown reasons, and it also is altered following stroke. Brain aging is associated with a progressive increase of the levels of inflammatory cytokine in the brain. Likewise, stroke causes pronounced increases of inflammatory cytokines in the brain. Following stroke, plasticity of the cortical representation following sensory deprivation and visualized with [14C]-2-deoxyglucose autoradiography is impaired for several weeks. Likewise, pl...

Assessment and Functional Impact of Allocentric Neglect: A Reminder from a Case Study.
We report here that SR suffers from both viewer-centered (i.e., egocentric) and object-centered (i.e., allocentric) spatial neglect. Notably, unlike most neuropsychological and functional assessments that focus on egocentric deficits, a specialized neuropsychological figurative discrimination test (the Apples test) revealed SR's allocentric neglect. Further, using assessments sensitive to detect functional deficits related to allocentric neglect, we observed SR's difficulty in reading and using clocks, reflecting his object-centered errors in these everyday activities. SR's case suggests that allocentric-specific assessmen...

Preliminary Evidence of Disparities in Physical Activity among Adolescents with Bipolar Disorder
Conclusions Frontal-executive dysfunction implicates frontal brain regions, which are known to be susceptible to oxidative damage. Further studies are needed, and those examining psychiatric populations may be especially fruitful. Focusing on youth may yield enhanced signal detection. Further study is needed to identify which antioxidant interventions work best for which cognitive functions and for which patients.

Cultural entrainment of motor skill development: Learning to write hiragana in Japanese primary school
Abstract The aim of the present study was to examine how the social norms shared in a classroom environment influence the development of movement dynamics of handwriting of children who participate in the environment. To look into this issue, the following aspects of the entire period of classroom learning of hiragana letters in Japanese 1st graders who had just entered primary school were studied: First, the structure of classroom events and the specific types of interaction and learning within such environment were described. Second, in the experiment involving 6‐year‐old children who participated in the class, writi...

Motor control of handwriting in the developing brain: A review.
Abstract This review focuses on the acquisition of writing motor aspects in adults, and in 5-to 12-year-old children without learning disabilities. We first describe the behavioural aspects of adult writing and dominant models based on the notion of motor programs. We show that handwriting acquisition is characterized by the transition from reactive movements programmed stroke-by-stroke in younger children, to an automatic control of the whole trajectory when the motor programs are memorized at about 10 years old. Then, we describe the neural correlates of adult writing, and the changes that could occur with learn...

Test Validity and Performance Validity: Considerations in Providing a Framework for Development of an Ability-Focused Neuropsychological Test Battery.
Abstract Literature on test validity and performance validity is reviewed to propose a framework for specification of an ability-focused battery (AFB). Factor analysis supports six domains of ability: first, verbal symbolic; secondly, visuoperceptual and visuospatial judgment and problem solving; thirdly, sensorimotor skills; fourthly, attention/working memory; fifthly, processing speed; finally, learning and memory (which can be divided into verbal and visual subdomains). The AFB should include at least three measures for each of the six domains, selected based on various criteria for validity including sensitivi...
