Factors linked to mortality after traumatic brain injury

Exercise may sharpen the mind by repairing the brain's protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein, causing the blood-brain barrier to become leaky with age.

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of the index and ring fingers, a marker of prenatal exposure to oestrogen and testosterone, researchers found that higher prenatal oestrogen exposure was associated with larger head size in newborn boys.

New research suggests that consistent aerobic exercise can help keep your brain biologically younger. Adults who exercised regularly for a year showed brains that appeared nearly a year younger than those who didn't change their habits.

The scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons.

A massive international brain study has revealed that memory decline with age isn't driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time.

When two people work on a shared task, they process information alike, a new study revealed.

A new study led by researchers at University College London (UCL) shows that chronic exposure to toxic air can significantly diminish the health benefits of regular physical activity.

Scientists discovered that more muscle and less hidden abdominal fat are linked to a younger biological brain age.

Researchers discovered that raising the protein Sox9 can help the brain's astrocytes clear out toxic plaque buildup linked to Alzheimer's.

Hypertension may impair the brain far earlier than previously understood -- even before a measurable rise in blood pressure occurs -- according to a new preclinical study from Weill Cornell Medicine. The changes help explain why hypertension is a major risk factor for developing cognitive disorders, such as vascular cognitive impairment and Alzheimer's disease.
