A Kaiser Permanente Southern California cohort involving 294,937 children linked extreme prenatal nighttime heat to autism diagnosis by age 5, with stronger associations at the 99th percentile than the 90th percentile.1 Compared with nighttime minimum temperature, daytime maximum temperature did not show the same confirmed whole-pregnancy pattern.

Restless legs syndrome (RLS), now also called Willis-Ekbom disease (WED), is a sleep-disrupting neurologic disorder that affects roughly 20–30% of pregnancies in some series and is linked to preeclampsia, increased cesarean delivery, and perinatal depression. A 2026 Nature and Science of Sleep synthesis turned 9 source documents into 27 practice recommendations across 5 domains, ending …
The depression-inflammation literature has firmly established that elevated inflammatory markers track with mood symptoms, but a 2026 study of 14,419 postpartum women from Xie et al. found the opposite pattern for postpartum anxiety: women with higher second-trimester platelet-neutrophil products and related immune-inflammation indices had substantially lower postpartum anxiety risk.1 Research Highlights Higher second-trimester PPN was …

Most popular framing still treats lithium as a uniquely dangerous fetal exposure to be avoided when possible. The new Chauhan UK cohort shows what …
For two decades, headlines have linked autism to maternal obesity, depression, anxiety, gestational diabetes, infection, autoimmune disease, and antidepressant use. The studies behind those headlines are well-replicated registry associations. A new design from the Aarhus University iPSYCH group offers the most careful answer yet to what they mean for an individual pregnancy. Most “maternal X …
Postpartum depression (PPD) is a serious mental health issue affecting many new mothers, impacting their well-being and their ability to bond with their child. Recent research suggests that inflammation could play a crucial role in the development of depression, opening the door to innovative treatments. A new case report highlights the potential of celecoxib, an …
New research has just surfaced from Johns Hopkins indicating that there is likely a link between prenatal exposure to antidepressant drugs and autism spectrum disorder (ASD) as well as other developmental delays (DD) among boys.
