Unraveling Long COVID: Inflammation and Tiny Clots Behind Prolonged Symptoms
What Long COVID Might Be Telling Us About Our Bodies While most people recover from acute COVID-19 within a few weeks, a significant subset experiences lingering symptoms that can persist for months. Scientists are racing to understand the biology behind long COVID, and the leading theories point to several overlapping problems. Inflammation that stubbornly lingers,…

Long COVID: How Inflammation and Tiny Clots Might Drive Persistent Symptoms
Understanding Long COVID: Beyond the Initial Infection Long COVID remains a complex and evolving condition. While many people recover from the acute phase of COVID-19, a subset experiences persistent symptoms that linger for weeks or months. Scientists are now piecing together a multifaceted picture: lingering virus particles in the body, ongoing low-grade inflammation, and tiny…

Fetal Brain Development and Memory: Sex Differences in Aging
Overview: Why fetal development matters for memory aging Memory decline and Alzheimer’s disease (AD) loom large as the population ages. New evidence underscores a surprising source of risk that starts long before birth: the fetal brain’s exposure to the maternal immune environment. In particular, elevated pro-inflammatory cytokines during pregnancy may sculpt memory circuits in ways…

Fetal Immune Activation Shapes Memory Aging: Sex Differences
Intro: How early brain development influences aging and memory Population aging in the United States is accelerating, with projections showing a growing share of adults aged 65 and older. While lifestyle, genetics, and health conditions influence memory in later life, mounting evidence points to prenatal periods as a foundational phase that can shape memory circuits…

Fetal Origins of Memory Impairment: Sex Differences in Aging
Overview: How early-life factors shape memory in later life New evidence suggests that critical processes during fetal brain development can influence memory and cognitive resilience decades later. Researchers led by Jill Goldstein, PhD, MPH, from the Innovation Center on Sex Differences in Medicine at Mass General are examining how sex and reproductive history modulate the…
