Given changes in prescribing practices in epilepsy over the past 2 decades, we enrolled a new cohort of the Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study to determine whether fetal exposure to newer generation ASMs is associated with altered cerebral lateralization in children at age 6\u2009years and to assess exposure\u2010dependent effects on handedness, manual dexterity, and verbal\/nonverbal abilities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The MONEAD multicenter prospective cohort study followed children of women with epilepsy (WWE) on ASMs and healthy women (HW) until age 6\u2009years.
