MARBLES is a longitudinal study for pregnant women who have previously given birth to a child with autism. The MARBLES study, which began in 2006, investigates possible pre-natal and post-partum exposures and risk factors that may contribute to the development of autism.

Why is MARBLES unique?
MARBLES gathers information over a long range of time, during both pre-natal and post-partum time periods. As a result, MARBLES is able to gather accurate information about the conditions to which the baby is exposed.

Our Study Goals:
MARBLES seeks to identify early markers of autism. By doing so, MARBLES eventually hopes to develop early diagnostic protocols and early intervention strategies to limit the effects of autism or to prevent it altogether.
