Key Highlights
•
A new, simpler method for measuring pain modulation in the body uses a TENS unit and a blood pressure cuff, showing better consistency between different testers compared to older methods. This could make it easier for doctors to identify patients whose nervous systems don’t dampen pain effectively, which is linked to worse outcomes in chronic pain conditions.

A large genetic study in an East Asian population has identified new genes linked to key Alzheimer’s disease blood markers, including a gene called DACT1 that appears to regulate a specific tau protein in brain cells called oligodendrocytes. This discovery helps explain the biological roots of these biomarkers and could lead to better, ancestry-specific tools for early detection and tracking of Alzheimer’s.

The risk of a disease relapse after receiving a meningococcal vaccine appears to be very low for patients with a specific autoimmune disorder of the nervous system (anti-AQP4 antibody-positive NMOSD). This is important safety information for patients and doctors, suggesting vaccination can be considered with a low expected risk of triggering a flare-up.
