poor brain development, delayed anatomical development, an enlarged and dysfunctional placenta,

There are much finer medical minds than mine on this board but I can certainly see how #3 could cause #'s 1 and 2.  I don't know if this will help but you might look it over.

Outlook

Placental insufficiency can’t be cured, but it can be managed. It’s extremely important to receive an early diagnosis and adequate prenatal care. These can improve the baby’s chances of normal growth and decrease the risks of birth complications. According to Mount Sinai Hospital, the best outlook occurs when the condition is caught between 12 and 20 weeks. 

Your OB-GYN should be your first point of contact.

Good luck, dear.
