Christensen, PhD, of The Australian National University, says, "If you read pregnancy manuals and listen to pregnant mothers -- yes, there is such a thing as pregnancy brain or momnesia. And there is also evidence from research showing deficits in memory." But, she adds, "the evidence from our study shows that the capacity of the brain is unaltered in pregnancy."
