objective: the aim of present research is to investigate the effects of neurofeedback on cognitive function with emphasis on memory. method: this study is an experimental study. for this reason using a stratified sampling procedure sample of 30 subjects in 2 groups of experimental and placebo was selected. investigated subjects were assessed with the wechsler memory scale in two stages (pretest...

objective: suicide rate is unfortunately increasing in recent years and its assessment is a must. most studies have evaluated different factors like personality, depression, or environment in suicide attempters but cognitive functions have been overlooked in suicide attempters. the current research aimed to evaluate a kind of cognitive function, namely attention in survivors of suicide.  method...

Introduction Adenotonsillar hypertrophy is a common disorder among children which, without proper treatment, may lead to considerable problems. Although the consequences of this disorder have been studied in other articles, we decided to evaluate the changes in pulmonary function tests in these children after adenotonsillectomy, and the correlation between clinical and spirometric parameters.  ...

objective: memory and concentration may be affected by hemodialysis in end-stage renal disease. in this study, changes in cognitive function parameters such as attention, impulsiveness, and reaction time were measured and evaluated in the iranian hemodialysing patients. methods: in this analytic observational study, cognitive function of 38 hemodialysis patients was measured before and after he...

a characteristic of data envelopment analysis (dea) is to allow individual decision making units (dmus) to select the factor weights which are the most advantageous for them in calculating their efficiency scores. this flexibility in selecting the weights, on the other hand, deters the comparison among dmus on a common base. for dealing with this difficulty and assessing all the dmus on the sam...
