IQ predicts many measures of life success, as well as trajectories of brain development. Prolonged cortical thickening observed in individuals with high IQ might reflect an extended period of synaptogenesis and high environmental sensitivity or plasticity. We tested this hypothesis by examining the timing of changes in the magnitude of genetic and environmental influences on IQ as a function of...

Cognitive intelligence is rarely discussed in the context of digital inequality for practical and normative reasons: substantial difficulties around measurements fact that it cannot (easily) be changed. In current contribution, cognitive studied relation to resources appropriation theory which explains as a process four successive phases Internet access: motivational, material, skills, usage. F...

Ten years follow-up investigation of intellectual development of 250 persons from Belarus exposed in utero following the Chernobyl accident has been conducted. Exposed cohort was compared with a control group of 250 persons in the same age from nonand slightly contaminated regions. For each study subject, individual antenatal doses were reconstructed for the following pathways of exposure: (1) ...

The issue of transplantation for patients affected by mental retardation (MR) has been and continues to be a matter of discussion. The recent policy of the Veneto region, a highly populated area in northern Italy, indicates that patients with MR are not eligible for any transplant of solid organs, indicating intelligence quotient (IQ) <50 as absolute and IQ <70 as a relative exclusion criteria....

A linkage study using two different restriction fragment length polymorphisms (RFLPs) identified with cloned DNA sequences has failed to provide evidence for genetic heterogeneity in Duchenne muscular dystrophy (DMD) when tested against intelligence quotient (IQ). Analysis of data for age of confinement to a wheelchair against IQ gave no evidence for heterogeneity. These results are of a practi...

OBJECTIVE Prevalence of allergies is different around the world. Allergic rhinitis is a common chronic disease in children. Intelligence quotient (IQ) is an indicator of efficacy and many factors including chronic diseases may affect it. This study compares the IQs of children diagnosed with persistent or perennial allergic rhinitis with healthy children. MATERIAL & METHODS This was a compara...

Studies of amniotic testosterone in humans suggest that fetal testosterone (fT) is related to specific (but not all) sexually dimorphic aspects of cognition and behaviour. It has also been suggested that autism may be an extreme manifestation of some male-typical traits, both in terms of cognition and neuroanatomy. In this paper, we examine the possibility of a link between autistic traits and ...

AIMS To prospectively study the surgical outcomes of unilateral anterior temporal lobectomy (ATL) in patients with intractable bilateral temporal lobe epilepsy (TLE) as well as two-staged contralateral hippocampal stimulation in patients after failed unilateral ATL. METHODS Eighteen carefully selected patients with bilateral TLE underwent unilateral ATL. Five cases with failed ATL underwent t...

General cognitive abnormalities Most patients with schizophrenia perform poorly on standard tests of intelligence. Several studies have shown that this general cognitive impairment reflects a decline from premorbid levels.’ In a study of a large population of patients in Harrow, the average discrepancy between estimates of current and premorbid intelligence was 16 intelligence quotient (IQ) poi...
