High-Fat diet tested as emergency brain fuel for injured kids

This small pilot study is checking if a special high-fat, low-carbohydrate diet (called a ketogenic diet) is safe and practical to use for children in intensive care with serious, sudden brain injuries like stroke or severe head trauma. The idea is that after an injury, the brain struggles to use sugar for energy, so this diet might provide an alternative fuel source called ketones. The study will monitor a few children on this special tube-feeding formula for two weeks to see if ketones appear in their blood and brain, and to watch for any side effects.
