Blood tests are best at detecting Alzheimer's disease: Study

Health experts warn that interpreting the advice literally can lead to excessive calorie intake, unhealthy weight gain and a higher risk of Gestational Diabetes Mellitus (GDM), a condition that affects blood sugar levels during pregnancy.

A new study suggests that eating more fat rather than less could help the body gain greater benefits from exercise when blood sugar levels are high, offering an unexpected perspective on how diet and physical activity work together to support metabolic health.

Living at high altitude appears to protect against diabetes, and scientists have finally discovered the reason. When oxygen levels drop, red blood cells switch into a new metabolic mode and absorb large amounts of glucose from the blood.

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.

Alzheimer's has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain's energy supply help drive the disease, and restoring that balance can reverse damage, even in advanced cases.

Scientists have discovered new anti-ageing compounds produced by a little-studied blood bacterium, opening up promising avenues for future skin-rejuvenation therapies.

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.

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.

In a study published November 5 in Nature, the team found that microglia with lower levels of a transcription factor called PU.1 and higher expression of a receptor known as CD28 help reduce brain inflammation.
