Social factors such as social distancing and reduced social support were associated with these decreases, while stress-related factors played a lesser role for most students.

Loss of placental hormone linked to brain and social behavior changes

A new study in mice suggests that preterm birth may alter long-term brain development due to the loss of placental hormone allopregnanolone. Reduced ALLO levels led to changes in brain structure and behavior, including autism-like behaviors, which were prevented with a single injection of ALLO.
