King’s Staging of ALS Linked to Distinct Brain Connectivity Changes on FDG-PET
Key Highlights
Medicine · Neurology
A large cross-sectional study of 832 ALS patients used 18F-FDG-PET to investigate brain connectivity correlates of King’s clinical staging. The researchers identified a decreasing metabolic gradient from King’s stage 1 to stage 3 in a cluster encompassing both motor and cognitive areas, with progressive loss of connectivity. This work suggests that FDG-PET imaging could be integrated with King’s staging to better assess the extent of the pathogenic process in clinical trials, offering a potential biomarker for disease spread and compensatory mechanisms.
