Benefits of Yoga practice on body posture and on psychological and cognitive functions in children aged 8-10 years

Background. Many authors have reported benefits related to yoga practice. In particular, the scientific literature showed the influences of yoga on physical performance and cognitive functions. However, only few researches have examined the role of this training practice in children. For this reason, the purpose of the present study was to investigate the effects on body posture and features as self-esteem and attention in children aged 8-10 years. Materials and method. Sixty-five subjects (male n=28, female n=37) aged 8-10 years and attending primary school were enrolled for the study and randomly assigned into an experimental group (EG) which included 28 participants and a control group (…

Se professionnaliser dans un dispositif de formation spécialisée

2013

Les nouvelles modalités de scolarisation des élèves handicapés interrogent les enseignants dans l’exercice de leur métier, en particulier ceux qui sont confrontés aux inscrits dans les troubles importants des fonctions cognitives. Les dispositifs de formation et d’accompagnement aident à identifier les compétences constitutives d’une nouvelle identité professionnelle enseignante et contribuent à initier et à enrichir ce processus de transformation identitaire. L’analyse des regards portés par les enseignants inscrits en formation spécialisée par alternance permet de mieux cerner les conditions requises afin que les leviers de transformation des postures et des pratiques professionnelles se …

Updated overview on interplay between physical exercise, neurotrophins, and cognitive function in humans

2019

Highlights • Physical exercise maintains or improves cognitive functions, and neurotrophin receptor signaling may play an important role. • A positive relationship exists between physical exercise and circulating brain-derived neurotrophic factor levels. • Less clear evidence has been found for a relationship between physical exercise and other neurotrophin levels, such as nerve growth factor, neurotrophin-3, and neurotrophin-4. • The postexercise variation of brain-derived neurotrophic factor might be associated with improvement of neurocognitive functioning. • Physical exercise may be an inexpensive and safe strategy for boosting brain-derived neurotrophic factor release, thus preserving …

Sequence Learning in a Single Trial: A Spiking Neurons Model Based on Hippocampal Circuitry.

2020

ABSTRACTIn contrast with our everyday experience using brain circuits, it can take a prohibitively long time to train a computational system to produce the correct sequence of outputs in the presence of a series of inputs. This suggests that something important is missing in the way in which models are trying to reproduce basic cognitive functions. In this work, we introduce a new neuronal network architecture that is able to learn, in a single trial, an arbitrary long sequence of any known objects. The key point of the model is the explicit use of mechanisms and circuitry observed in the hippocampus, which allow the model to reach a level of efficiency and accuracy that, to the best of our…

Social networks and social activities promote cognitive functioning in both concurrent and prospective time: evidence from the SHARE survey

2018

The study aimed to investigate the role of social activities, social networks as well as socioeconomic status (SES) in influencing some aspects of cognitive functioning (immediate and delayed verbal recall tests and semantic verbal fluency) in elderly people over time. This analysis was conducted on a sample of 31,954 healthy elderly people (58% female, mean age 65.54 ± 9.74) interviewed in both the fourth and sixth waves of the Survey on Health, Aging and Retirement in Europe (SHARE), in 2011 and 2015. A structural equation model with measurement component was used to assess the relationship between cognitive function, social life and SES over time. Multilevel ordinal logistic regression w…

Adverse Clinical Events and Mortality During Hospitalization and 3 Months After Discharge in Cognitively Impaired Elderly Patients

2012

BACKGROUND: Controversial findings are reported on hospital outcome in cognitively impaired patients. The aim of this study was to explore mortality risk according to cognitive status during hospitalization and after 3 months in elderly patients. METHODS: Sixty-six internal medicine and geriatric wards in Italy participated in the "Registry Politerapie SIMI (REPOSI)" during 2010. Of the 1,380 in-patients, aged 65 and older enrolled, 1,201 were included. Cognition was evaluated with the Short Blessed Test (SBT). Logistic regression was used to evaluate the association of questionable and impaired cognition (according to SBT cutoff points) with mortality during hospitalization and at follow-u…

Stroke is increasingly recognized as an important cause of cognitive problems and has been implicated in the development of both Alzheimer's disease and vascular dementia. Th…

Specialised English Lexicography. A Contrastive Analysis of two Monolingual Medical Dictionaries

2020

Today information tends to be increasingly specialised. Moreover, English is the language of most scientific literature worldwide. Within this framework, English dictionaries are very important reference tools which help improve exchange among members of a given professional community. Of the different specialised languages, the medical one perhaps undergoes the fastest changes parallel to the continuous and rapid advances in medical sciences. However, research on medical lexicography seems to lack studies on monolingual medical dictionaries – especially from a comparative synchronic and diachronic point of view. This paper intends to offer a contrastive analysis of some features of two of …

Effects on executive functions of antiepileptic monotherapy in pediatric age.

2020

Abstract Objectives Cognitive abilities and executive functions in children and adolescents are important indicators of quality of life as well as academic and social achievements. Cognitive and executive functioning are often impaired in patients with epilepsy and can be exacerbated by seizures and antiseizure drugs. The aim of our observational retrospective study was to assess executive functioning in patients with pediatric epilepsy, currently taking a single antiseizure medication. Materials and methods Records of 172 children and adolescents aged between 6 and 18 years (mean age = 12 ± 3.4 years) with newly diagnosed epilepsy who had not yet commenced an antiepileptic treatment were i…

Memory for time intervals is impaired in left hemi-Parkinson patients.

2004

The basal ganglia have been proposed as one of the neural correlates of timekeeping functions. Both encoding and memory retrieval components for time perception are impaired in Parkinson's disease (PD). The aim of our study was to investigate in hemi-Parkinsonian patients the existence of a specific alteration in memory for time depending on the affected side, to better understand the contribution of the left or right basal ganglia circuits in different components of time perception. Right and left hemi-PD patients performed a time reproduction task in which they were required to reproduce in the same session short (5 s) and long (15 s) time intervals, in off- and on-therapy condition. Whil…
