Key differences in male and female mice brains provide new insights into how sex determines the mechanisms by which distinct synapses monitor and regulate dopamine signaling. The impact of sex differences is particularly pronounced when the mice express a human genetic variant found in boys with either ADHD or autism. Behavioral generalizations across the sexes may limit diagnosis of mental illness, especially if one sex translates alterations into outward signs such as hyperactivity and aggression vs. more internal manifestations such as learning, memory and mood, even when the same molecular pathology is at work.

Since the early 1990s, federal support of research has increased to understand minority health and identify and address health disparities. Research in these areas has evolved from a starting point of developing a basic descriptive understanding of health disparities and who is most affected. Now, it is discovering the underlying complexity of factors involved in health outcomes to inform interventions and reduce these disparities. One of these many factors is where we live, learn, work, and play and how that affects different people. A group of NIH scientists and their colleagues recently published a study in the journal The Lancet that they hope is a step toward better understanding geographic disparities and their role in health equity.

An advanced computer program was able to identify people with Parkinson’s disease from their breathing patterns during sleep. The program was able to track small changes in the disease over time, and was more accurate than the tools used regularly by doctors.

Cardiovascular disease, which affects the heart and blood vessels, is the nation’s leading cause of death, and Black Americans bear a disproportionate burden. Nearly half of Black adults in this country have cardiovascular disease. Their risk of dying from the condition is 30% higher than the overall U.S. population’s.
