The research suggests that both ApoE4 and poor vascular health independently increase depression risk, not a compounded effect.
A new study suggests that maternal postpartum depression is associated with difficult infant temperaments when maternal sensitivity is low, but not when it is high. Family functioning also plays a critical role in shaping an infant's behavioral style.

The study analyzed 12 studies and found no correlation between exercise intensity or frequency and the effectiveness of exercise in reducing postpartum depression.
