Do you think moms who suffer from PPD inadvertently has a negative effect on the children as well?

An article in Scientific American discusses how PPD can affect more than the mother. The article states that ...

The consequences of depression inevitably reach beyond the mother. In a fog of sadness, a mother often lacks the emotional energy to relate appropriately to her baby. Overwhelming grief prevents her from properly perceiving a child’s smiles, cries, gestures and other attempts to communicate with her. Getting no response from mom, the child quits trying to relate to her. Thus, three-month-old infants of depressed mothers look at their mothers less often and show fewer signs of positive emotion than do babies of mentally healthy moms.

Do you agree with this statement? And if you've experienced PPD yourself and found the above treatment true, what did you do to reconnect with your child?
