Mother infant interaction in depressive mothers using Near-infrared spectroscopy(NIRS)

The objective of this study was to examine differences in the prefrontal cortex blood flow in babies when cuddled by their depressed mothers and their normal mothers. The depressive emotions of the mothers were measured using the Edinburgh PostnatalDepression Scale (EPDS). Then, by using near infrared spectroscopy (NIRS), the changes in the cerebral blood flow were measured while mothers with high EPDS scores and those with low scores interacted with their babies. The results showed that when mothers with high depression scores interacted with their babies, no major changes in hemoglobin concentrations occurred before and after the interaction; however, the oxyhemoglobin concentrations increased immediately after the interaction began. This suggests that changes in the cerebral blood flow duringmother-child interactions vary depending on the level of depression that the mother is experiencing. However, further data are required to carefully verify the reproducibility of these results.
