A new study argues that attention impairment, not memory loss, should be the central focus for early dementia diagnosis. The research highlights how “attentional overload” impacts daily life and suggests new ways to improve care.

A new meta-analysis reveals no link between hormonal contraception and idiopathic intracranial hypertension (IIH). The findings offer reassurance to women using birth control, as the study found no increased risk across pills, IUDs, or implants.

Researchers have shown that the primary visual cortex (V1) computes statistical summaries of complex motion, such as mean and variance. This “ensemble perception” starts early in the visual hierarchy, allowing the brain to rapidly grasp the gist of a scene.

A massive study of 700,000 people shows that ADHD medication in childhood does not increase the risk of psychosis. In fact, starting treatment before age 13 may help protect against schizophrenia in adulthood.

Does infection cause dementia? New research shows severe bacterial infections and UTIs are linked to increased dementia risk, independent of other health factors. Learn how infections might accelerate brain aging.

Immersive dreaming, rather than just slow-wave brain activity, is what makes us feel well-rested. Vivid, bizarre dreams provide a higher sense of sleep depth by better disconnecting the brain from the outside world.

A new study finds that AI-generated “deepfake” X-rays are realistic enough to deceive both radiologists and top-tier AI models. Researchers warn that these synthetic images pose a major risk for medical fraud and hospital cybersecurity.
