Experiencing complications during pregnancy is linked with a higher risk of stroke before age 50, according to a study published August 6, 2025, in Neurology^®, the medical journal of the American Academy of Neurology. Researchers found female participants who had certain pregnancy complications were more likely to have an early stroke. These included preeclampsia, preterm birth, gestational diabetes, miscarriage and stillbirth. The study does not prove that pregnancy complications cause stroke. It only shows an association.

Mount Sinai researchers have demonstrated the effectiveness of teaching surgical trainees a difficult procedure using artificial intelligence (AI) algorithms and an extended-reality headset without the presence of an instructor. All of the 17 trainees in the study achieved surgical success. The novel study, published in Journal of Medical Extended Reality, drew highly favorable reviews from student participants who tested the deep learning model. The results carry significant implications for future training of residents and surgeons, as well as for the even broader field of autonomous learning within medicine.
