Key Highlights
•
A new gene therapy approach using a virus to deliver targeted microRNAs successfully silenced a harmful viral protein linked to ALS in mice, reducing motor neuron loss and improving movement. This provides a promising new strategy for treating forms of ALS that are driven by this specific viral protein.

Children and teenagers with multiple sclerosis (MS) have shorter telomeres—a marker of biological aging—than healthy children of the same age, suggesting the disease itself may accelerate the body’s aging process. This finding strengthens the idea that MS is not just an immune attack but also impacts fundamental cellular aging.

Subtle language difficulties, like forgetting names, appear in the earliest biological stages of Alzheimer’s disease, even before memory problems are noticeable on standard tests. This means that tracking language changes could help detect Alzheimer’s much earlier, aligning cognitive symptoms with the underlying brain pathology.

An international panel of experts has established the first consensus guidelines for evaluating and managing hypothalamic hamartomas, rare brain growths that cause severe seizures. This provides a much-needed standardized roadmap for doctors worldwide to diagnose and treat this complex condition more effectively.

Brain activity patterns measured by EEG show a significant imbalance in people with obesity, pointing to altered brain dynamics that may be linked to appetite and impulse control. This evidence suggests that obesity involves changes in fundamental brain network organization, not just behavior or metabolism.
