BACKGROUND A number of studies have investigated cognitive impairment in paediatric patients with multiple sclerosis (MS) but deficits regarding executive functions have not been comprehensively assessed up to now. This study was meant to explore cognitive impairment in German paediatric MS patients with a focus on deficits in executive functions and relate these to clinical disease parameters....
Background and Objective: Evaluation of neurocognitive mechanism involved in smoking can be helpful in the treatment of this dependence .The aim of this study was to compare the cognitive executive functions in frontal lobe of brain in male smokers and non-smokers. Materiasl and Methods: The method of research was causative-comparitive. In this regard, 40 male smokers and 40 male non-smokers...
Cognitive disorders are one of the major public health issues in older population worldwide. Problems in forming and storing new memories, short-term memory impairment, and other cognitive problems are common symptoms of cognitive disorders that have no definite treatment yet. Recent studies have shown an association between gut microbiota and cognitive impairments described as microbiota-gut-...
‎The complex system containing n elements‎, ‎each having three dependent components‎, ‎is described‎. ‎The reliability function of such systems is investigated using a trivariate binomial model‎. ‎In addition‎, ‎the mean residual life function of a complex system with intact components at time t is derived‎. ‎The results are simplified for a t...
Objective: Methadone maintenance treatment is one of the most common methods of substance abuse treatment. There is conflicting evidence of the effect of methadone on behavior and cognition. The aim of this study was to evaluate the effect of methadone maintenance treatment on executive functions. Method: A quasi-experimental research design along with pretest and posttest stages was used for t...
Introduction: Previous findings from our laboratory indicated that exercise alleviates the deficits in cognitive and anxiety disorders in healthy female rats. But the effect of exercise on cognitive and anxiety disorders induced by chronic morphine in experimental monopose of rats (ovariectomized) not known. Aim of this study was to investigate the effects of mild and modorate forced exercise o...
A central question in cognitive neuroscience concerns the extent to which language enables other higher cognitive functions. In the case of mathematics, the resources of the language faculty, both lexical and syntactic, have been claimed to be important for exact calculation, and some functional brain imaging studies have shown that calculation is associated with activation of a network of left...
Prefrontal cortex (PFC) supports flexible behavior by mediating cognitive control, though the elemental forms of control supported by PFC remain a central debate. Dorsolateral PFC (DLPFC) is thought to guide response selection under conditions of response conflict or, alternatively, may refresh recently active representations within working memory. Lateral frontopolar cortex (FPC) may also adju...
