Abstract
OBJECTIVE: The traumatic loss of an unborn child
by induced termination of pregnancy because of fetal malformation
is a major life event that causes intense maternal grief. Increasing
evidence supports the hypothesis that the same neural structures
involved in the experience of physical pain are involved in the
experience of social pain and loss. METHOD: To investigate neural
activation patterns related to acute grief, the authors conducted
a functional MRI study of 12 post-termination women and 12 noninduced
women who delivered a healthy child. Brain activation was measured
while participants viewed pictures of happy baby, happy adult,
and neutral adult faces. RESULTS: Relative to comparison women,
post-termination women showed greater activation in the middle
and posterior cingulate gyrus, the inferior frontal gyrus, the
middle temporal gyrus, the thalamus, and the brainstem in response
to viewing happy baby faces. Functional connectivity between
the cingulate gyrus and the thalamus during the processing of
happy baby faces was significantly stronger in post-termination
women. CONCLUSIONS: Overall, acute grief after the loss of an
unborn child was closely related to the activation of the physical
pain network encompassing the cingulate gyrus, the inferior frontal
gyrus, the thalamus, and the brainstem. To the authors' knowledge,
the stronger functional thalamocingulate connectivity in post-termination
women is the first in vivo demonstration of an involvement of
the neural maternal attachment network in grief after the loss
of an unborn child.
