Children with sickle cell disease, silent strokes show some relief with blood transfusions

A Phase II study found that blood transfusion therapy helped shrink brain lesions caused by silent strokes in children with sickle cell disease. The therapy eliminated one lesion completely and showed no new silent strokes after two years. Researchers hope to preserve cognitive function in these children through prolonged transfusions.

Is there a developmental component to the risk for depression?

Researchers identified six courses of mental health, with poorer outcomes associated with smaller birth weight and delayed developmental milestones. The study suggests a 'fetal programming' model for depression and anxiety, where prenatal stress may result in permanent maladaptive changes to the developing fetal brain.
