Long COVID Brain Fog Linked to Inflammation and Stress Markers

A new study comparing long COVID patients with fully recovered individuals has found that those with persistent cognitive symptoms, like brain fog, show higher brain inflammation and reduced capacity to handle stress. The study revealed lower levels of nerve growth factor and elevated inflammatory markers in the long COVID group.

New Insights Into Why Stress Is So Hard to Treat

A new review reveals key differences in how stress hormone systems function in primate versus rodent brains, offering insight into why treatments for stress-related disorders often fail in humans. Researchers found that corticotropin releasing factor (CRF) interacts with dopamine circuits in more complex and widespread ways in primates, with dopamine neurons often releasing multiple neurotransmitters.

Dopamine’s Hidden Role in Anxiety Revealed

Dopamine receptors in the ventral hippocampus play a critical role in balancing approach and avoidance behaviors, expanding understanding beyond dopamine’s known functions in reward and motivation. By studying D1 and D2 receptor-expressing neurons in mice, researchers found these receptors govern opposing emotional responses under stress.

Prenatal Stress Leaves Lasting Molecular Imprints on Babies

A new study reveals that stress during pregnancy can molecularly reprogram newborns' stress response systems, with significant differences between boys and girls. Researchers found that maternal stress altered entire families of tRNA fragments in umbilical cord blood, particularly those regulating acetylcholine, a key neurotransmitter.

Only Children Face Unique Struggles as Parental Caregivers

As single-child families rise in the U.S., more adults are navigating the intense responsibility of caregiving without the support of siblings. A new study reveals that only children experience greater emotional and financial stress when caring for aging parents, and support from friends or extended family doesn't offer the same relief it does for those with siblings.

Nearly Half of U.S. Adults Report Weekly Stress from News

A new national survey reveals that 45% of U.S. adults experience stress at least once a week due to news or social media, with 16% feeling stressed daily. While stress is a natural response to caring deeply about issues or people, chronic exposure without relief can negatively affect both mental and physical health.

Fear Sync: How Males and Females Respond to Stress Together

When mice face fear, they often freeze—and when paired, they typically freeze together. A new study reveals that male-female pairs maintain synchronized fear responses even under stress, unlike same-sex pairs.

Prenatal Stress Timing Shapes Infant Stress Response

New research reveals that the timing of stress during pregnancy has gender-specific effects on infants, altering how boys and girls respond to stress differently. Scientists found mid-pregnancy stress has a stronger impact on girls' stress reactivity, while boys are more sensitive to stress experienced in late gestation.

Brain Changes From Early-Life Stress May Be Reversible

A new study reveals how prenatal infections followed by early-life stress—known as "two-hit stress"—can lead to brain dysfunction and psychiatric-like behaviors. Researchers found that affected mice showed abnormal cerebellar activity, increased microglial turnover, and impaired brain-wide connectivity.

Early Life Stress Rewires Brain Circuits Linked to Social Motivation

New research shows that early life stress disrupts dopamine signaling, altering social motivation and behavior. Scientists found that mice raised in stressful conditions were less likely to engage in social interactions compared to those with enriched experiences.

Prenatal Stress Hormones Alter Brain Development

Environmental factors like stress and medication exposure during pregnancy can shape brain development, but the mechanisms remain unclear. Researchers used brain organoids to study the effects of synthetic glucocorticoids, commonly given to prevent complications in premature births.
