Exposure During Pregnancy
Links to Learning Disabilities, ADD and Behavior Disorders
The following is one chapter from a 1997 Graduate Student Research Project conducted at the University of South Florida. The project involved locating published peer reviewed medical journal articles which have shown various environmental and chemical exposure factors can cause learning disabilities, hyperactivity and other disorders by damaging the delicate brain growth process in the unborn child during pregnancy.

New warnings should be given to pregnant women taking the heart arrhythmia drug "Amiodarone" (AMD). Researchers at the Department of Medicine, Mount Sinai Hospital, Toronto, ON, Canada have found when this drug was taken during pregnancy that there was an observed increase in language disorders at a later age for children exposed to the drug during pregnancy. In the research project, the offspring of 12 mothers were followed after giving birth while taking the drug.
A sophisticated battery of tests were given to determine neurological function of the offspring. Tests included - Bayley Behavior Scales - Reynell Developmental Language Test - Toddler Temperament Test - WISC-R - WRAT-R and Gilmore Oral Reading Test.
While there were no deficits detected in IQ scores, there was an observed significant delay in speech acquistition and lower scores on tests of reading comprehension, written language, arithmetic skills and/or attention.
