A low-cost, noninvasive eye scan could help detect Alzheimer’s disease earlier than current methods. The technique may expand access to early diagnosis, especially in underserved communities, and provide a valuable tool for intervention before irreversible brain damage occurs.

New findings suggest that dysfunction in the brain’s glymphatic system—a key waste clearance pathway—may contribute to cognitive impairments in adults with ADHD, shedding light on a lesser-known biological mechanism behind the disorder.

A new study shows that parents who experience pride and awe in everyday moments with their children report higher life satisfaction, deeper meaning, and greater emotional richness—highlighting the powerful psychological benefits of these emotions in family life.

Scientists have discovered that increasing levels of a protein called Hevin in the brain reverses memory loss in aging and Alzheimer’s model mice. The findings suggest a new way to improve cognition without targeting amyloid plaques.

Vaporized DMT produced fast and lasting improvements in depression symptoms and suicidal ideation, according to a new phase 2a trial, highlighting its potential as a scalable, non-invasive alternative to conventional and long-acting psychedelic treatments for severe depression.

A brain scan study comparing dementia patients to healthy individuals reveals how frontotemporal dementia impairs emotional empathy. The findings could help scientists understand the disease’s early progression and eventually guide development of targeted interventions.

New research reveals that serotonin in the gut lining can reduce anxiety and depression symptoms in mice—without the side effects of traditional antidepressants—and may offer a safer alternative for treating mood disorders during pregnancy.

Research on adolescents exposed to early trauma reveals impaired fear learning: those with childhood adversity showed less ability to distinguish safety from threat and were more prone to overgeneralize fear, highlighting a possible pathway to future mental health problems.

A recent review published in Cureus explores the relationship between caffeine and Alzheimer’s disease. The findings suggest that higher caffeine intake may reduce the risk of cognitive decline, especially in people with early symptoms of memory impairment.

A new study finds that postnatal depression may impair the body’s hormonal response to breastfeeding. While oxytocin nasal spray boosted breast milk levels in healthy mothers, the same effect was not seen in those experiencing depressive symptoms after childbirth.

Researchers have found that women who exhibit inattentive ADHD symptoms report lower orgasmic consistency during partnered sex, while those with hyperactive-impulsive symptoms may experience more consistent orgasms—underscoring the relationships between attention, distraction, and sexual satisfaction.

A new study suggests that girls whose parents fail to reciprocate eye contact or positive facial expressions during conflict may be more likely to experience suicidal thoughts later. These subtle interaction patterns could serve as early behavioral indicators of risk.

Researchers analyzed wearable device data, brain scans, and genetic profiles to explore links between physical activity and mental health in adolescents. Moderate levels of activity were associated with lower symptom scores, while excessive activity showed no added benefit.

In a rodent model of childhood adversity, escitalopram treatment during adolescence reduced signs of emotional distress. The study also found gene-level changes in the endocannabinoid system, pointing to a possible biological mechanism for the drug’s effectiveness.
