Key Highlights
•
A new study shows that specific combinations of proteins in the blood can predict the buildup of harmful plaques and tangles in the brain, which are hallmarks of Alzheimer’s disease. This means a simple blood test could one day help doctors detect Alzheimer’s early and monitor its progression, offering a cheaper and more accessible alternative to brain scans.

Researchers have successfully used a gene therapy approach to silence a specific virus-like protein in the brain and spinal cord of mice, which slowed down the loss of motor neurons and improved their movement. This finding is a promising step toward a potential new treatment for ALS (Lou Gehrig’s disease), a devastating condition with no current cure.

A large study found that higher levels of certain proteins in the blood that indicate brain cell damage are linked to a higher risk of death from any cause, including dementia. This suggests that these blood markers could be used to identify people at greater risk of severe health decline, allowing for earlier monitoring and care.

Scientists have discovered that a specific genetic variant, previously thought to cause disease only when inherited from both parents, can also cause a common inherited nerve disorder when inherited from just one parent. This expands the genetic testing needed for patients with nerve damage, ensuring more people get an accurate diagnosis.

The severity of bronchiolitis, a common lung infection in infants, is connected to problems with the body’s immune “brakes,” known as checkpoints. Understanding this link could lead to new ways to predict which babies will get very sick and potentially to treatments that calm the overactive immune response.
