Episode Highlights
Parkinson's
Dr. George Brooks discusses the potential of lactate in treating Parkinson's disease. He highlights studies showing that forced exercise in Parkinson's patients improves motor and memory tasks, likely due to lactate fueling neurons in the brain. Brooks also mentions research on lactate's positive effects on mitochondrial function in animal models of Parkinson's disease 1.
Alzheimer's
Lactate's role in treating Alzheimer's disease is another area of interest. Dr. Brooks explains that higher lactate levels in patients with moderate to severe traumatic brain injury correlate with better recovery outcomes. This suggests lactate's potential in aiding brain recovery and function 2.
Neuroprotection
Lactate serves as a neuroprotective agent by acting as both an energy source and a signaling molecule. Dr. Brooks describes how lactate regulates gene transcription related to mitochondrial function and muscle adaptation. He also discusses the potential benefits of lactate infusion in traumatic brain injury patients, emphasizing the importance of early intervention 3 4.
