XX. SCF LAYMAN’S SUMMARY
GLUT1 deficiency syndrome is a rare genetic disorder in which the brain cannot efficiently transport glucose across the blood–brain barrier. Because glucose is the brain’s primary fuel, affected individuals experience chronic cerebral energy deprivation that leads to seizures, developmental delays, cognitive difficulties, and movement disorders. One of the most effective treatments is a ketogenic diet, which provides ketones as an alternative fuel source for the brain. SCF interprets GLUT1 deficiency as a systems-level cerebral fuel-delivery disorder involving nutrient-transport failure, neuroenergetic instability, synaptic dysfunction, and loss of synchronized brain energy management.
