Dl-3-n-Butylphthalide Protects against Memory Deficits in Vascular Dementia Rats by Attenuating Pyroptosis via TLR-4/NF- κB Signaling Pathway
Conclusion: These findings demonstrate that NBP protects against memory deficits in permanent bilateral common carotid artery occlusion-induced VD rats by attenuating pyroptosis via the TLR-4/NF- κB signaling pathway.Neuropsychobiology

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

At the Heart of Neurological Dimensionality: Cross-Nosological and Multimodal Cardiac Interoceptive Deficits
Conclusions Our result suggests a diffuse pattern of interoceptive alterations across neurological conditions, highlighting their potential role as dimensional, transdiagnostic markers.

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 relationship of cognitive change over time to the self-reported Ascertain Dementia 8-item Questionnaire in a general population.
CONCLUSIONS: Incident cognitive impairment and high depression risk were the strongest predictors of self-reported positive AD8 in this population-based sample. Our results inform the utility of the AD8 as a self-report measure in a large, national sample that avoids selection biases inherent in clinic-based studies. The AD8 is screening measure and should not be used to diagnose dementia clinically. PMID: 32613226 [PubMed - as supplied by publisher]

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]

Use of the parallel beam task for skilled walking in a rat model of cerebral ischemia: A qualitative approach
Publication date: February 2018Source: Learning and Motivation, Volume 61Author(s): Brian Ficiur, Jamshid Faraji, Gerlinde A.S. MetzAbstractThe parallel beam task (PBT), in which animals walk across two elevated parallel beams, is commonly used to assess motor deficits in laboratory rodents. Performance of the PBT challenges postural balance, inter-limb coordination and skilled walking abilities, and is typically assessed by quantitative measures such as number of foot slips and/or successful traversals. We proposed that including qualitative movement analysis of skilled walking would increase resolution and sensitivity of...

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.

The Chinese Australian Neuropsychological Normative Study: Neuropsychological Test Norms for Chinese Australians Aged 55 –90 Years
ConclusionThe influence of demographic variables and reliability coefficients of neuropsychological tests developed for dominant western cultural groups cannot be assumed to be the same across CALD groups. Use of CALD‐specific norms is recommended to increase the reliability and validity of neuropsychological testing.

Learning to write: The role of handwriting for Chinese spelling in kindergarten children.
Given the orthographic complexities of Chinese characters, handwriting skills may play an important role in how children learn to write Chinese. The present study includes a comprehensive battery of handwriting measures in relation to Chinese spelling in young children. Measures of handwriting, including stroke order, visual-motor integration (Hebrew and Vietnamese copying) and handwriting fluency, along with other reading-related cognitive skills, were administered to 141 kindergartners in Hong Kong schools. We assessed the extent to which these handwriting measures are associated with spelling. A series of regression ana...

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...

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.
