introduction: intelligence is the ability of using the different powers and effective behaviors or adapting to new situations or diagnosing conditions and qualities of the environment. it seems that a considerable damage to the brain as a result of premature birth in the last weeks of pregnancy in the maturational - structuring process of the brain can be correlated with intelligent quotient (i...

Neuroimaging research indicates that human intellectual ability is associated to brain structure including the thickness of the cerebral cortex. Most studies show that general intelligence is positively associated with cortical thickness in areas of association cortex allocated throughout both brain hemispheres. Changes in cortical thickness over time have been related to intelligence, but whet...

Mental retardation(MR) was defined by the World Health Organisation as an intelligent quotient (IQ)<70 that is accompanied by adaptive limitations in two or more key skills areas, before the age of 18. General intellectual functioning is expressed by IQ. Typically, in chil‐ dren younger than 5 years old who present delays in the attainment of developmental mile‐ stones at the expected age, the ...

This study was designed to compare the Intelligence Quotient (IQ) among 3 to 7-year-old strabismic and nonstrabismic children in an Iranian population. In this cross-sectional study, 108 preschool children with equal numbers of strabismic/non-strabismic disorder (age 3-7 years) were randomly selected from exceptional strabismus clinics of Ahvaz and were evaluated with the preschool and primary ...

Introduction: Attention Deficit Hyeperactivity Disorder (ADHD) is a relatively prevalent disorder in children and is associated with some other disorders including depression. This problem also affects the emotional characteristics and intelligence quotient. The aim of this study was to examine the relationship of Emotional Characteristics (EC) and depression with Intelligence Quotient (IQ) in ...

background: lead still remains an important problem for poor, inner-city, ethnic minority children, with a particular emphasis on lead paint and dust. in egypt, there is no national survey about the prevalence of elevated blood lead level among children. objective: to assess the environmental lead level as well as to determine blood lead level among primary school children and find out its rela...

SUMMARY In order to evaluate psychomotor activity and intelligent quotient in schoolchildren of iodine deficient region, 95 children from Kiga and 103 from Keshar villages and 73 from Razi school in Tehran were studied. In Kiga there is moderately severe iodine deficiency with retarded physical growth and decreased thyroid function. These students had more errors in Bender-Gestalt (BG) test an...

Changes in cortical thickness over time have been related to intelligence, but whether changes in cortical surface area are related to general cognitive functioning is unknown. We therefore examined the relationship between intelligence quotient (IQ) and changes in cortical thickness and surface over time in 504 healthy subjects. At 10 years of age, more intelligent children have a slightly thi...

background and objectives : considering the effect of heavy metals (particularly lead) on intelligent quotient level , it was measured in children living in high lead areas in angouran district of zanjan province . material and methods : in this historical cohort study all( n=64 ) grade – one students living in angouran village were selected as case group. 62 other students living in low lead a...
