Summary: Women born in states with higher structural sexism experience faster memory decline later in life, with effects equivalent to nine years of cognitive aging. Structural sexism encompasses societal inequities like unequal labor force participation and underrepresentation in government, which create systemic barriers to health.The impact is particularly pronounced among

Summary: Researchers have linked chronic intestinal infections caused by cytomegalovirus (HCMV) to a unique subtype of Alzheimer’s disease. The virus may travel from the gut to the brain via the vagus nerve, altering immune responses and contributing to hallmark Alzheimer’s changes like amyloid plaques and tau tangles.While HCMV infection is

Summary: Researchers used AI to analyze brain images from 70-year-olds, estimating their biological brain age and uncovering connections to lifestyle and health factors. Diabetes, inflammation, and high glucose levels were linked to older-looking brains, while regular exercise and healthy habits were associated with younger-looking brains.The study highlights the importance of

Summary: A new study has revealed how brain circuits and neurotransmitters regulate meal initiation, offering insights into obesity management.Researchers identified serotonin neurons in the midbrain’s dorsal Raphe nucleus (DRN) as key players, inhibited by GABA and dopamine when hunger strikes. This inhibition lowers serotonin levels, triggering feeding behavior, while satiety

Summary: Alcohol use disorder (AUD) disrupts cognitive flexibility, crucial for learning and adapting to change. New research reveals that chronic alcohol exposure alters the firing patterns of cholinergic interneurons (CINs), key neurons in the brain’s striatum that regulate dopamine and influence reward-driven learning.Normally, CINs fire in a burst-pause pattern vital

Summary: A study highlights significant improvements in the physical and mental functioning of older adults in England compared to previous generations. Using data from the English Longitudinal Study of Aging, researchers found that advancements in education, nutrition, sanitation, and medical care have likely contributed to better health outcomes.For instance, a
