BACKGROUND: Word reading and linguistic comprehension skills are two crucial components in reading comprehension, according to the Simple View of Reading (SVR). Some researchers have posited that a third component should be involved in reading and understanding texts, namely executive function (EF) skills. AIM: This study was novel in two ways. Not only did we tested EF skills as a predictor of reading comprehension in a non-alphabetic language (i.e., Chinese) to extend the theoretical model of SVR, we also examined reading comprehension further in kindergarten children (age 5) in Hong Kong, in the attempt to reveal possible early precursors of reading comprehension...

OBJECTIVES: Generalized tonic-clonic status epilepticus (GTC-SE) is considered a risk for cognitive impairment. Research with standardized tools is scarce and non-conclusive. We systematically assessed short-term and long-term cognitive function after GTC-SE. MATERIALS AND METHODS: Thirty-three patients were tested after the clinical post-ictal phase of GTC-SE (timepoint 1) and again after 1 year (timepoint 2). Twenty controls were examined with the same tests...

Memories of fearful events can be maintained throughout the lifetime of animals. Here we showed that lesions of the lateral nucleus (LA) performed shortly after training impaired the retention of long-term memories, assessed by the concomitant measurement of two dissociable defensive responses, freezing and avoidance in rats. Strikingly, when LA lesions were performed four weeks after training, rats did not show freezing to a learned threat stimulus, but they were able to direct their responses away from it...

DHA is an important component of neural lipids accumulating in neural tissue during development. Inadequate DHA in gestation may compromise infant development, but it is unknown whether there are lasting effects. We sought to determine whether the observed effects of fetal DHA inadequacy on infant development persist into early childhood. This follow-up study assessed children (5-6 years) whose mothers received 400 mg/d DHA or a placebo during pregnancy. Child neurodevelopment was assessed with several age-appropriate tests including the Kaufman Assessment Battery for Children...

In this pilot study, we investigate whether a routine cycle ergometry training programme has therapeutic potential in individuals with multiple sclerosis (MS) by improving quality of life (QOL) and depressive symptomatology, while ameliorating cognitive disturbances. Healthy volunteers and MS patients cycled for 30 min at 65-75% age-predicted maximal heart rate on a recumbent ergometer, with this session repeated twice a week for 8 weeks. QOL, depressive symptomatology and cognitive function were assessed pre- and post-exercise using the MS Quality of Life-54 (MSQOL-54) questionnaire, 16-item Quick Inventory of Depressive Symptomatology (QIDS-SR16) questionnaire and the Cambridge Neuropsychological Test Automated Battery (CANTAB), respectively...

Exposure to enriched environment (EE) is known to promote sensory, cognitive, and motor stimulation with intensified levels of novelty and complexity. In this study, we investigated the positive regulatory effect of short-term exposure to EE on establishing functional recovery in monosodium glutamate (MSG)-induced obese rats. Unless treated, MSG rats exhibited peripheral insulin resistance, cognitive deficits, and a reduction in the total hippocampal volume with decreased neuron count in the DG, CA3, and CA1 subfields...

Recent studies suggest that the mechanisms involved in the short-term retention of serial order information may be shared across short-term memory (STM) domains such as verbal and visuospatial STM. Given the intrinsic sequential organization of musical material, the study of STM for musical information may be particularly informative about serial order retention processes and their domain-generality. The present experiment examined serial order STM for verbal and musical sequences in participants with no advanced musical expertise and experienced musicians...

Evidence in the literature suggests that listening to music can improve cognitive performance. The aim of the present study was to examine whether the short- and long-term gains of a working memory (WM) training in older adults could be enhanced by music listening-the Mozart's Sonata K448 and the Albinoni's Adagio in G minor-which differ in tempo and mode. Seventy-two healthy older adults (age range: 65-75 years) participated in the study. They were divided into four groups. At each training session, before starting the WM training activities, one group listened to Mozart (Mozart group, N = 19), one to Albinoni (Albinoni group, N = 19), one to white noise (White noise group, N = 16), while one served as an active control group involved in other activities and was not exposed to any music (active control group, N = 18)...

Background: Attentional dysfunctions constitute core cognitive symptoms in schizophrenia, but the precise underlying neurocognitive mechanisms remain to be elucidated. Methods: In this randomized, double-blind, sham-controlled study, we applied, for the first time, a theoretically grounded modeling approach based on Bundesen's Theory of Visual Attention (TVA) to (i) identify specific visual attentional parameters affected in schizophrenia and (ii) assess, as a proof of concept, the potential of single-dose anodal transcranial direct current stimulation (tDCS; 20 min, 2 mA) to the left dorsolateral prefrontal cortex to modulate these attentional parameters...

Parkinson's disease (PD) is a dopaminergic neurodegenerative disorder, which presents motor and non-motor symptoms.7-Fluoro-1,3-diphenylisoquinoline (FDPI) is an isoquinoline compound with antioxidant and antidepressant properties. This study investigated whether FDPI reverses motor and non-motor symptoms in an acute mouse model of PD induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). It was also assessed the anti-inflammatory mechanisms in FDPI pharmacological action. C57Bl/6 male adult mice received four MPTP (20mg/kg, intraperitoneal) or saline (vehicle) injections to induce an acute PD model...

BACKGROUND: Previous research has suggested that there is a degree of variability among older adults' response to memory training, such that some individuals benefit more than others. The aim of the present study was to identify the profile of older adults who were likely to benefit most from a strategic memory training program that has previously proved to be effective in improving memory in healthy older adults. METHOD: In total, 44 older adults (60-83 years) participated in a strategic memory training...

BACKGROUND: The incidence of proximal humeral fractures increases with age. The functional recovery of the upper arm after such fractures is slow, and results are often disappointing. Treatment is associated with long immobilisation periods. Evidence-based exercise guidelines are missing. Loss of muscle mass as well as reduced range of motion and motor performance are common consequences. These losses could be partly counteracted by training interventions using robot-assisted arm support of the affected arm derived from neurorehabilitation...
