Results of studies investigating the long-term effects of intra-uterine exposure to antiepileptic drugs (AEDs) on cognitive functioning are limited and conflicting. To estimate intellectual development of children prenatally exposed or unexposed to AEDs by assessing IQ scores in a systematic review and meta-analysis.

Brief Report: Relationship between non-verbal IQ and gender in autism.

It has been proposed that females at risk for autism are protected in some way, so that only those with the greatest genetic liability are affected. Consequently, affected male siblings of females with autism should be more impaired than affected male siblings of male probands. One hundred and ninety-four (194) families with a single child with autism (simplex, SPX) and 154 families with more than one child with autism (multiplex, MPX) were examined on measures of severity, including non-verbal IQ.
